How Can Genetics Influence Cholesterol Levels?

Aira on February 2, 2024

Understanding Cholesterol

Cholesterol is indispensable for human life, orchestrating various roles behind the scenes to ensure the smooth functioning of our cells. Serving as a fundamental structural component of cell membranes, it also takes center stage in the creation of vitamin D, and essential hormones, and plays a pivotal role in the digestion process.

This vital molecule, due to its aversion to water, relies on lipoproteins as its transport vehicles within the bloodstream, hitching a ride alongside triglycerides. Lipoprotein analysis in clinical settings aids in estimating the cholesterol levels in our blood. Additionally, maintaining the delicate balance of cholesterol is paramount for heart health.

Elevated cholesterol levels, along with markers like C-reactive protein (CRP), can have significant implications, underscoring the importance of actively managing and sustaining optimal cholesterol levels.

Good vs. Bad Cholesterol

Good and bad “cholesterol” actually refer to two types of lipoproteins that carry cholesterol in the blood.

LDL (low-density lipoprotein) is sometimes called “bad cholesterol” because it can build up in the walls of the arteries and form plaques, which can narrow the blood vessels and increase the risk of heart disease and stroke.
HDL (high-density lipoprotein) is sometimes called “good cholesterol” because it can help remove excess cholesterol from the blood and carry it back to the liver, where it is broken down and eliminated from the body. This can lower the risk of heart disease and stroke.

Additionally, triglycerides are another type of fat in the blood that can also affect the risk of heart disease and stroke. High levels of triglycerides, especially when combined with low HDL or high LDL, can increase the risk of fatty buildup in the arteries.

The Role of Cholesterol in the Body

Cholesterol is not always the villain it is portrayed to be. It is a vital substance that our bodies produce and use for various functions. Cholesterol is also found in some foods, mainly animal products, that we consume.

The body relies on cholesterol to:

Contribute to the construction of new tissue and mend damage in existing tissue
Play a role in the production of steroid hormones, including estrogen
Assist in the creation of bile in the liver
Facilitate the production of vitamin D

However, despite these vital roles, an excess of (“bad”) cholesterol can pose serious risks, potentially leading to life-threatening conditions like cardiovascular disease and kidney issues. Balancing cholesterol levels is essential for overall health.

Genetics of Cholesterol Levels

Genetic factors may play a crucial role in determining cholesterol levels and inflammation in the body, both of which are linked to cardiovascular health.

Previous studies have identified several genes that influence the levels of high-density lipoprotein (HDL) and low-density lipoprotein (LDL) cholesterol, as well as C-reactive protein (CRP), a marker of inflammation.

ABO Gene

Interestingly, while ABO gene variation is more known as forming the basis for ABO blood groups, The ABO gene also plays a crucial role in regulating LDL cholesterol levels, as indicated by a genome-wide association study (GWAS) involving 94,674 individuals. This study revealed evidence of genetic dominance and epistatic interaction with the FUT2 gene at the ABO gene (at SNP rs2519093), highlighting its impact on the complexity of genetic influences on lipid metabolism.

STAG1 Gene

STAG1 reveals potential pleiotropic effects, influencing both the CRP and HDL cholesterol levels. The bivariate GWAS revealed the SNP rs7621025, located near STAG1, as a significant player in the shared biology of chronic inflammation and lipid metabolism. The subsequent replication analysis validated its association with both CRP and HDL cholesterol, emphasizing its role in orchestrating genetic harmony between these two crucial physiological markers.

FTO Gene

The FTO gene plays a role in cholesterol levels. Through a comprehensive GWAS analysis, the SNP rs1558902 near FTO emerged as a significant genetic marker influencing HDL. The FTO gene is known as the “obesity gene” and this finding highlights the importance of the FTO gene variation and the total lipid status for overall health.

These genetic insights offer a direct view into the genes influencing HDL and LDL cholesterol, as well as the known inflammation marker CRP levels, contributing to a deeper understanding of the genetic foundations of cardiovascular health.

Non-Genetic Factors Influencing Cholesterol Levels

While genetics play a role in cholesterol levels, there are also several other factors that genes can interact with. Understanding these factors is crucial for proactive health management. Below are some key contributors to be mindful of.

Lifestyle Habits

Unhealthy lifestyle habits significantly contribute to imbalanced cholesterol levels. Consuming foods high in saturated fats, such as fatty cuts of meat and certain dairy products, elevates LDL cholesterol. It is recommended that no more than 10% of daily calories come from saturated fats. Lack of physical activity, smoking, chronic stress, and excessive alcohol consumption further disrupt cholesterol balance. Adopting heart-healthy lifestyle changes, including a balanced diet and regular exercise, is pivotal in managing and preventing unfavorable cholesterol levels.

Medications

Certain medications prescribed for various health concerns can influence cholesterol levels. Medications such as beta-blockers, diuretics, immunosuppressive drugs, chemotherapy agents, retinoids, and steroids may raise LDL cholesterol or lower HDL cholesterol. Individuals taking these medications should be aware of their potential impact on cholesterol and work with healthcare providers to monitor and manage cholesterol levels effectively.

Age

Age-related changes in metabolism can affect cholesterol regulation. As individuals age, the liver may become less efficient at removing LDL cholesterol, increasing the risk of high cholesterol. High total cholesterol can affect individuals of all ages, including young children, but it is most commonly diagnosed in people between the ages of 40 and 59. Understanding the normal age-related changes in cholesterol metabolism is essential for addressing cholesterol concerns as one gets older.

Race or Ethnicity

Race or ethnicity can influence cholesterol levels, with variations observed among different groups. Non-Hispanic white individuals are more likely to have high total cholesterol, while Asian Americans may have elevated levels of LDL cholesterol. Hispanic Americans often exhibit lower levels of HDL cholesterol, and African Americans are more likely to have higher levels of HDL cholesterol but may face other risk factors, such as high blood pressure and diabetes.

Gender

Cholesterol levels vary between genders and across different life stages. Men between the ages of 20 and 39 generally have a higher risk of high total cholesterol. However, women’s risk increases after menopause, as hormonal changes lead to higher total and LDL cholesterol levels, along with lower levels of protective HDL cholesterol. Understanding these gender-specific patterns is crucial for tailoring cholesterol management strategies.

Lifestyle Changes to Manage Cholesterol Levels

Managing cholesterol levels involves a combination of dietary changes, physical activity, and lifestyle modifications. Here are some ways to manage your cholesterol levels:

Eat heart-healthy foods: A few changes in your diet can reduce total cholesterol and improve your heart health:
- Reduce saturated fats – Found primarily in red meat and full-fat dairy products, these raise your total cholesterol.
- Eliminate trans fats – Often used in margarine and store-bought cookies, crackers, and cakes, trans fats raise overall cholesterol levels.
- Eat foods rich in omega-3 fatty acids – Foods with omega-3 fatty acids, such as salmon, mackerel, herring, walnuts, and flaxseeds, have heart-healthy benefits, including reducing blood pressure.
- Increase soluble fiber – Soluble fiber, found in foods like oatmeal, kidney beans, Brussels sprouts, apples, and pears, can reduce the absorption of cholesterol into your bloodstream.
Exercise regularly: Moderate physical activity can help raise high-density lipoprotein (HDL) cholesterol, the “good” cholesterol. Aim for at least 30 minutes of exercise five times a week or vigorous aerobic activity for 20 minutes three times a week.
Quit smoking: Quitting smoking improves your HDL cholesterol level.
Maintain a healthy weight: Carrying even a few extra pounds can contribute to high total cholesterol.
Drink alcohol only in moderation: Excessive drinking can lead to serious health problems, including high blood pressure, heart failure, and strokes.

The Genetics Of CoQ10 Requirements

Aira on January 30, 2024

Overview

What is CoQ10?

Coenzyme Q10 (CoQ10) is a naturally occurring antioxidant produced by the body, essential for cell growth and maintenance. It plays a crucial role in energy production and protects cells from oxidative damage. CoQ10 levels naturally decrease with age and can be lower in individuals with certain health conditions, particularly heart disease.

Although found in food items like meat, fish, and nuts, dietary sources are generally insufficient to increase body levels significantly. CoQ10 is available in supplement capsules and tablets, offering potential health benefits, especially for those with heart-related conditions.

CoQ10 level refers to the amount of Coenzyme Q10 present in the body and is typically measured in blood. Appropriate levels are important because CoQ10 is crucial for cell energy production and has antioxidant properties. Adequate levels are necessary for overall health and vital for the functioning of major organs like the heart.

Factors such as aging, certain health conditions, and the use of statins can lead to reduced CoQ10 levels. Monitoring these levels can be important in assessing an individual’s health status, especially in certain diseases or conditions.

What is the Difference Between Ubiquinol and Coenzyme Q10?

CoQ10 has two main forms: ubiquinone (oxidized) and ubiquinol (reduced). Ubiquinol is the active antioxidant form of CoQ10, and is more readily usable by the body. It plays a key role in cellular energy production and protecting cells from oxidative damage.

On the other hand, ubiquinone is the form more typically found in dietary supplements and it needs to be converted into ubiquinol in the body to exert its antioxidant effects. The body’s ability to convert ubiquinone to ubiquinol may decrease with age.

How Do You Know if Your CoQ10 Levels are Low?

Determining low CoQ10 levels typically involves symptom observation and clinical testing. Symptoms of low CoQ10 might include fatigue, muscle weakness, and high blood pressure, although these symptoms can be non-specific.

The most definitive way to ascertain CoQ10 levels is through a blood test, often used in clinical studies or specialized medical evaluations. This test measures the concentration of CoQ10 in the blood and can help diagnose deficiencies, particularly in individuals with certain medical conditions or those on statin therapy.

Is There a Blood Test to Check CoQ10 Levels?

Yes, a blood test is available to measure CoQ10 levels. This specialized test assesses the concentration of CoQ10 in the bloodstream, providing valuable insights into an individual’s CoQ10 status.

Such testing is particularly relevant for those with conditions potentially linked to CoQ10 deficiency, such as heart disease, or for individuals taking statins which are known to lower CoQ10 levels. The test can guide healthcare providers in diagnosing deficiencies and recommending appropriate interventions, including supplementation.

Do Statins Deplete CoQ10 Levels?

Statins, commonly prescribed cholesterol-lowering medications, are known to deplete CoQ10 levels in the body. This depletion occurs because statins inhibit the pathway synthesizing both cholesterol and CoQ10. Reduced CoQ10 levels can lead to various side effects, including muscle pain and weakness, which statin users commonly report.

Understanding this interaction is important for managing the potential side effects of statin therapy, and CoQ10 supplementation is often considered to mitigate these effects.

Genetics Of CoQ10 Levels

A 2011 pilot study examined the influence of genetic variations on CoQ10 levels. CoQ10 is crucial for mitochondrial energy production and acts as an antioxidant. The research focused on non-synonymous single-nucleotide polymorphisms (SNPs) in genes related to CoQ10 biosynthesis, reduction, and metabolism.

Initial CoQ10 levels in heterozygous NQO1 P187S carriers were notably lower compared to homozygous carriers. After CoQ10 supplementation, individuals with the APOE4/E4 genotype showed a significant increase in CoQ10 levels compared to those with the APOE2/E3 genotype. The study suggests that NQO1 P187S and certain APOE polymorphisms may impact CoQ10 status in humans.

A 2016 study investigated the genetic factors influencing serum CoQ10 levels. A meta-analysis of two Northern German cohorts identified two significant genetic loci linked to CoQ10 levels. The COLEC12 gene on chromosome 18 and the NRXN-1 gene on chromosome 2, previously associated with neuronal diseases, showed the strongest associations. This research suggests that common genetic variants, particularly those linked to neurological conditions, may significantly impact serum CoQ10 levels.

Non-Genetic Factors Affecting CoQ10 Levels

Non-genetic factors affecting CoQ10 levels include age, as levels naturally decrease with advancing age. Certain medical conditions, especially those affecting the heart or muscles, can also lower CoQ10 levels.

Dietary intake can influence levels, though food sources generally provide limited amounts. Lifestyle factors, such as physical activity and stress, might have an impact. Additionally, medications, particularly statins used for cholesterol management, are known to reduce CoQ10 levels in the body.

How Do Genes Influence Your Vitamin C Needs?

Aira on December 4, 2023

Overview

Vitamin C, also known as ascorbic acid, is an essential water-soluble nutrient and powerful antioxidant. It plays a crucial role in several bodily functions:

Immune Function

Vitamin C supports the immune system by stimulating the production and function of white blood cells and acting as an antioxidant.

Collagen Synthesis

Vitamin C is vital for collagen synthesis, healthy skin, wound healing, and maintaining the integrity of connective tissues.

Antioxidant Function

As an antioxidant, vitamin C helps combat free radicals in the body, reducing oxidative stress and potentially lowering the risk of chronic diseases.

Iron Absorption

Vitamin C enhances the absorption of non-heme iron, the form of iron found in plant-based foods, which is critical for preventing anemia among vegetarians.

The recommended daily intake of vitamin C is 90mg for men and 75 mg per day for women. However, for women, the need increases to 85 mg during pregnancy and 120 mg while breastfeeding.

While vitamin C is generally safe, excessive intake (usually from supplements, not food) can lead to adverse effects like diarrhea, nausea, and stomach cramps. The upper limit for adults is 2,000 mg per day. Taking too much over a prolonged period can lead to more health issues.

Vitamin C intake depends on age, sex, and specific health conditions. Adhering to the recommended dietary allowances through a balanced diet or standard supplements is sufficient and safe.

Genetics Of Vitamin C Needs

Before we get into the genetics of vitamin C status, it is essential to understand how the body absorbs it.

Vitamin C absorption in the body primarily occurs in the small intestine through a mechanism involving sodium-dependent vitamin C transporters (SVCT1 and SVCT2). SVCT1, located in the small intestine, is responsible for the uptake of vitamin C from dietary sources. Once absorbed, vitamin C moves via the bloodstream to various tissues, where SVCT2 aids cell uptake.

The body regulates vitamin C absorption, and its efficiency can decrease as intake increases, meaning that very high doses are not effectively absorbed. Excess vitamin C gets excreted in the urine.

Genetics in Vitamin C Bioavailability

SLC23A1

The SLC23A1 gene encodes the SVCT1 protein. Predominantly located in the epithelial cells of the small intestine and kidneys, SVCT1 plays a vital role in absorbing vitamin C from dietary sources and reabsorbing it from the kidneys, thus regulating its levels in the body.

In 2010, a two-stage study evaluated the connection between genetic variations in the SLC23A1 gene and the levels of l-ascorbic acid (vitamin C) in the bloodstream. The first stage used the British Women’s Heart and Health Study as the discovery cohort, followed by a series of follow-up cohorts. The second stage was a meta-analysis that included a total of 15,087 participants.

The study found that a specific genetic variant, rs33972313 (C/T), located in the SLC23A1 gene (which encodes a vitamin C transporter), is associated with lower levels of l-ascorbic acid in the blood. Each additional copy of the minor allele (T) was linked to a decrease in l-ascorbic acid levels by approximately 5.98 μmol/L.

The significance of the rs33972313 variant in plasma vitamin C levels was further confirmed in a 2021 GWAS.

SLC23A2

The SLC23A2 gene encodes the SVCT2 protein. This transporter is expressed in almost all body tissues, particularly in areas with high metabolic activity, like the brain, eyes, and adrenal glands. SVCT2 ensures the delivery of vitamin C to these essential tissues, supporting its role in antioxidant protection and enzyme function.

In a 2011 case-control study conducted in the Mediterranean population, researchers identified a significant association between the rs1279386 (A>G) SNP in the SLC23A2 gene and the risk of primary open-angle glaucoma (POAG).

In their analysis, individuals homozygous for the G allele (GG) showed a higher risk of developing POAG when compared to other genotypes. Additionally, the study found that POAG patients generally had lower plasma vitamin C levels than control subjects.

Other Genes

In a 2021 GWAS, the researchers found a significant genetic association involving the SLC23A3 gene on chromosome 2. This gene encodes the sodium-dependent vitamin C transporter 3 (SVCT3), which is part of the same transporter family as SLC23A1. The SNP rs13028225 displayed a strong association with plasma vitamin C levels.

SVCT3 has a largely unknown functional role. However, existing evidence indicates that SVCT3 is primarily expressed in the kidneys. It suggests that genetic variations in SLC23A3 could influence circulating vitamin C levels by impacting renal function and consequently affecting vitamin C reabsorption in the kidneys.

The study also uncovered other candidate SNPs affecting vitamin C levels:

RER1: The rs6693447 variant in the RER1 gene, encoding the retention in endoplasmic reticulum sorting receptor 1, showed a significant association with vitamin C metabolism.
GSTA5: The rs7740812 variant in the GSTA5 gene, encoding glutathione S-transferase α 5.
SNRPF: The rs117885456 variant in the SNRPF gene, encoding small nuclear ribonucleoprotein polypeptide F.
CHPT1: The variant rs2559850 in the CHPT1 gene encodes choline phosphotransferase 1.
BCAS3: The rs9895661 variant in the BCAS3 gene, encoding microtubule-associated cell migration factor.

Non-Genetic Factors Affecting Vitamin C Levels

Diet: We get vitamin C from fruits and vegetables, with some of the richest sources being citrus fruits, berries, kiwi, bell peppers, and dark green leafy vegetables like kale and spinach. Notably, the vitamin C content in food can be reduced by prolonged storage and cooking, as vitamin C is water-soluble and sensitive to heat. Eating fresh and minimally cooked fruits and vegetables maximizes vitamin C intake.

Age and Gender: Vitamin C requirements vary across different ages and genders. For instance, infants have lower needs, while pregnant and breastfeeding women require higher amounts. Men generally require slightly more vitamin C than women. As people age, their ability to absorb vitamin C can decrease, potentially increasing their need for this nutrient.

Lifestyle Habits: Smoking significantly increases oxidative stress and metabolic demand for antioxidants. Hence, smokers require more vitamin C than non-smokers. Similarly, excessive alcohol consumption can impair the body’s ability to absorb and store vitamin C. It leads to reduced vitamin C levels.

Health Conditions: Certain illnesses, particularly those causing inflammation or fever, can increase the body’s need for vitamin C. Stress, both physical and emotional, elevates cortisol levels, which can deplete vitamin C stores. Chronic conditions, like diabetes and heart disease, may also increase the demand for vitamin C due to heightened oxidative stress.

Medications: Some medications, including certain types of birth control and aspirin, can lower vitamin C levels in the body. Diuretics, used for high blood pressure, increase the excretion of vitamin C, potentially leading to lower levels.

Environmental Factors: Exposure to pollutants and toxins, such as cigarette smoke (even second-hand) and heavy metals, can increase oxidative stress in the body, thereby increasing the need for vitamin C. Urban environments with higher pollution levels might contribute to a greater demand for antioxidants, including vitamin C, compared to less polluted areas.

Recommendations To Improve Vitamin C Levels

To improve vitamin C levels, consider these recommendations:

Increase Dietary Intake: Incorporate a variety of fruits and vegetables rich in vitamin C into your diet. Citrus fruits, strawberries, kiwi, bell peppers, broccoli, and spinach are excellent sources.
Opt for Raw or Lightly Cooked Foods: Since vitamin C is sensitive to heat, light, and air, eat fruits and vegetables raw or cook them lightly to preserve their vitamin C content.
Regular Supplementation: If dietary intake is insufficient, consider vitamin C supplements. It’s essential to stick to the recommended dosages unless advised otherwise by a healthcare provider.
Quit Smoking: Smoking significantly depletes vitamin C levels. Quitting smoking can help improve these levels. Smokers generally require higher amounts of vitamin C.
Limit Alcohol Consumption: Excessive alcohol can impair vitamin C absorption. Moderating alcohol intake can help maintain adequate vitamin C levels.
Manage Stress: Chronic stress can deplete vitamin C levels. Doing stress-reducing activities like exercise, meditation, or hobbies can be beneficial.
Regular Health Check-ups: Some health conditions and medications can affect Vitamin C levels. Regular check-ups can help manage these factors effectively.
Awareness of Environmental Factors: Be mindful of environmental pollutants and minimize exposure. You may want to consider using air purifiers, face masks, and ensuring adequate ventilation.

Understanding the Genetics Behind Your Glomerular Filtration Rate

Aira on December 1, 2023

Overview

What is the Glomerular Filtration Rate?

If you’ve ever had your blood drawn for tests, you would have noticed many components in the results. One of them is your body’s (estimated) glomerular filtration rate or eGFR. Glomerular filtration is a fundamental process within the human kidneys, playing a crucial role in the body’s ability to regulate fluid balance and eliminate waste products.

Situated in the renal corpuscle, the glomerulus is a network of tiny blood vessels tasked with filtering the blood to form urine. This filtration process, driven by the pressure gradient across the glomerular capillaries, allows essential substances like water, electrolytes, and small molecules to pass through the filtration barrier while retaining larger molecules like proteins and blood cells.

Fundamentally, glomerular filtration is an intricately calibrated system that preserves homeostasis by guaranteeing the removal of metabolic waste products without jeopardizing essential elements required for physiological processes. One of the most important markers of kidney function is the glomerular filtration rate (GFR), which measures the amount of fluid filtered by the glomerulus in a given amount of time.

Since differences in the genes linked to this process can affect an individual’s vulnerability to kidney disorders, understanding the genetic foundations of glomerular filtration has become a focus of nephrology studies.

Glomerular filtration is essentially the cornerstone of kidney function, demonstrating the complex interactions between filtration barriers, blood arteries, and genetic factors in the coordination of this essential physiological function.

Why is Glomerular Filtration Important?

The preservation of the body’s internal environment and general health depend critically on glomerular filtration. This process, which takes place in the kidneys and is the main means of eliminating waste and regulating fluid balance, is essential in preventing the build-up of toxic compounds in the blood.

Glomerular filtration maintains the body’s delicate balance by allowing just those vital elements—water, electrolytes, and tiny molecules—to flow through while trapping larger molecules and cells.

One important metric for evaluating renal function is the GFR. When the GFR deviates from the normal range, it may be a sign of possible kidney disease. This information can help with early renal problem identification and prompt action. Moreover, individual differences in kidney function and susceptibility to renal disorders are influenced by the hereditary components of glomerular filtration.

Comprehending these hereditary foundations is essential for customizing therapeutic strategies and creating focused treatments, ultimately improving our capacity to treat and avoid kidney-related illnesses.

What Affects Glomerular Filtration Rate?

Glomerular filtration rate (GFR) is influenced by various factors, including blood pressure, blood volume, and the permeability of the filtration barrier. Conditions such as hypertension can alter the pressure within the glomerular capillaries, impacting GFR. Changes in blood volume affect the rate at which blood is filtered in the kidneys.

Additionally, alterations in the permeability of the glomerular filtration barrier, influenced by factors like inflammation, can impact GFR. Hormonal regulation, especially through the renin-angiotensin-aldosterone system, also plays a crucial role.

Genetic Factors

Genetic markers associated with glomerular filtration rate (GFR) provide valuable insights into the individual variability in kidney function and susceptibility to renal diseases.

Several genetic factors contribute to the regulation of GFR, influencing the efficiency of the glomerular filtration process. While the genetic landscape of GFR is complex and involves numerous genes, some key markers have been identified through research.

SHROOM3 Gene

The SHROOM3 gene is involved in the regulation of cell shape and structure. Genetic variants in SHROOM3, such as the SNP rs17319721, have been linked to an increased risk of Chronic Kidney Disease (CKD) and reduced GFR. This gene is thought to play a role in the maintenance of the glomerular filtration barrier and overall kidney function.

APOL1 Gene

The APOL1 gene has been implicated in kidney disease susceptibility. Variants in this gene are associated with an increased risk of chronic kidney disease (CKD) and end-stage renal disease (ESRD). These variants may impact the permeability of the glomerular filtration barrier, influencing GFR.

UMOD Gene

The UMOD gene encodes uromodulin, a protein expressed in the kidneys. Uromodulin plays a role in regulating water and electrolyte balance. Genetic variations (such as SNP rs11864909) in UMOD have been linked to changes in GFR. Certain UMOD mutations are associated with a higher risk of CKD, emphasizing the gene’s relevance to kidney function.

EGFR Gene

The epidermal growth factor receptor (EGFR) gene is involved in cell growth and differentiation. Variations in this gene have been linked to changes in GFR, impacting renal function. EGF is part of the complex interplay of growth factors influencing the maintenance of glomerular structure and function.

NOS3 Gene

Nitric oxide synthase 3 (NOS3) produces nitric oxide, a molecule involved in blood vessel dilation. Genetic variations in NOS3 have been associated with endothelial dysfunction and altered renal blood flow, potentially impacting GFR. Dysfunction in nitric oxide signaling can contribute to the development of renal disorders.

LifeDNA’s GFR Genetic Markers

A study with 432 participants with Chronic Kidney Disease (CKD) identified eight gene variants (SNPs) linked to CKD risk, including CX3CR1, MTTP, PIP5K1B, APOA5, BRAP, SPATA5L1, and MCP1. Notably, specific SNPs in BRAP and SPATA5L1 were significantly associated with the eGFR. Furthermore, a genetic risk score (GRS) using the 8 SNPs was developed, and it could indicate up to a 17% higher risk for CKD.

Understanding genetic factors for GFR and CKD is crucial for personalized medicine and targeted interventions in the realm of nephrology. Genetic testing and research continue to unveil the intricate relationship between genetic variants and renal function, paving the way for advancements in the diagnosis, treatment, and prevention of kidney diseases.

Environmental Factors

Numerous non-genetic factors can affect the glomerular filtration rate (GFR), a crucial measure of kidney function. The intricate interplay of physiological systems that control renal function can also be influenced by these extrinsic factors. For the purpose of understanding kidney health and developing strategies to maintain optimal filtration rates, it is imperative to appreciate how environmental influences affect GFR.

Hydration Status

Drinking adequate amounts of water is essential to preserving GFR. Dehydration can cause blood volume to drop and blood viscosity to rise, which can change the pressure inside glomerular capillaries. This pressure change might affect the rate of filtration, which highlights how crucial it is to stay properly hydrated for the best possible kidney function.

Blood Pressure

Systemic blood pressure is a major factor in the control of GFR. Over time, glomerular capillaries may sustain damage from hypertension, or high blood pressure, which could result in a reduction in GFR. On the other hand, decreased blood pressure can lower the glomerulus’s filtration pressure, which would be detrimental to GFR.

Blood Glucose Levels

High blood sugar, which is a symptom of diabetes, can affect GFR and cause renal injury. Reduced GFR is frequently caused by diabetic nephropathy, a kidney condition associated with diabetes. Maintaining blood glucose control is essential for avoiding problems associated with diabetes, such as reduced kidney function.

Medications and Toxins

Nephrotoxic effects can be caused by some drugs and environmental pollutants, which can affect GFR directly. Substances that can impair renal function include exposure to heavy metals, some medicines, and nonsteroidal anti-inflammatory medications (NSAIDs). Maintaining GFR requires reducing exposure to nephrotoxic chemicals and being aware of the negative effects of medications.

Dietary Habits

Dietary choices influence GFR through their impact on blood pressure and metabolic factors. High-sodium diets can contribute to hypertension, affecting GFR. Additionally, excessive protein intake may increase the glomerular filtration load, potentially straining the kidneys over time.

Physical Activity

Frequent exercise is linked to cardiovascular health, which has an impact on GFR. Exercise supports good kidney function by promoting healthy blood pressure and cardiovascular health in general. Dehydration can result from strenuous physical activity without adequate hydration, which may have an impact on GFR.

Infections and Inflammation

Infections and inflammatory conditions can affect GFR by triggering immune responses and altering the permeability of the glomerular filtration barrier. Inflammatory kidney conditions, such as glomerulonephritis, can lead to decreased GFR.

Temperature and Climate

Environmental temperature can impact fluid balance and, consequently, GFR. Extreme heat can lead to increased fluid loss through sweating, potentially causing dehydration and affecting renal blood flow.

Altitude

Changes in altitude can influence oxygen levels in the blood and systemic blood pressure, which may impact GFR. Individuals living at higher altitudes may experience adaptations in renal function to compensate for lower oxygen levels.

Stress

Chronic stress and the associated activation of the sympathetic nervous system can lead to changes in blood pressure and systemic vascular resistance, potentially affecting GFR. Stress management strategies are crucial for overall health, including kidney function.

Numerous environmental and lifestyle factors that impact general health and well-being can have an impact on the eGFR. Maintaining kidney function and stopping the onset or progression of renal diseases need effective management of these outside factors.

Maintaining optimal GFR requires a comprehensive approach to health that includes blood pressure management, a balanced diet, lifestyle choices, and adequate hydration.

Is the Glomerular Filtration Rate Reversible?

Although some elements that affect GFR, including blood pressure fluctuations or dehydration, can be corrected with the right treatments, the GFR itself cannot be changed.

Dehydration is one of the factors that might cause a transient drop in GFR because it changes the filtration pressure and blood volume. Rehydrating and treating the underlying cause are frequently sufficient to return GFR to normal. Similar to this, some drugs or lifestyle modifications may have a favorable effect on GFR.

However, structural damage to the kidneys in situations of chronic kidney disease (CKD) or other persistent renal diseases may result in a persistent decline in GFR that is not entirely reversible. In these situations, the main goals of treatment are usually to control the underlying illness, reduce the rate at which the disease progresses, and treat the symptoms.

Some influences on GFR are reversible through appropriate measures but the overall GFR is a dynamic parameter influenced by various factors, and its reversibility depends on the underlying cause and the extent of structural damage to the kidneys.

Ways to Maintain Good Glomerular Filtration Rate

Maintaining a healthy Glomerular Filtration Rate (GFR) is essential for kidney function and overall well-being. While individual factors can vary, there are several lifestyle modifications and habits that may contribute to improving GFR and supporting optimal kidney health.

Hydration

Adequate hydration is crucial for optimal kidney function. Staying well-hydrated helps maintain blood volume and supports the kidneys in efficiently filtering waste products. Water intake should be adjusted based on individual needs, considering factors like climate, physical activity, and overall health.

Balanced Diet

Adopting a balanced and nutrient-rich diet is vital for kidney health. Focus on consuming a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit salt intake, as excessive sodium can contribute to hypertension and impact GFR. Additionally, moderate protein intake is recommended, as very high protein diets may strain the kidneys.

Regular Physical Activity

Engaging in regular exercise contributes to cardiovascular health and helps maintain optimal blood pressure levels. Cardiovascular activities, such as walking, jogging, or swimming, can support overall kidney function. However, intense and prolonged exercise without adequate hydration should be avoided to prevent dehydration-related stress on the kidneys.

Control Blood Pressure

Hypertension is a significant risk factor for kidney disease and reduced GFR. Monitoring and controlling blood pressure within the recommended range can help preserve kidney function. Lifestyle modifications, including a low-sodium diet, regular exercise, and stress management, are effective in managing blood pressure.

Manage Blood Sugar Levels

It’s critical for diabetics to keep their blood sugar levels steady. Diabetic nephropathy, a disorder that can eventually deteriorate kidney function, is a result of uncontrolled diabetes. To manage diabetes and maintain kidney health, lifestyle changes, medication adherence, and regular blood sugar testing are crucial.

Avoid Nephrotoxic Substances

Certain medications, including nonsteroidal anti-inflammatory drugs (NSAIDs), some antibiotics, and excessive use of certain other over-the-counter medications, can have nephrotoxic effects. It’s crucial to use medications as directed by healthcare professionals and avoid unnecessary exposure to substances that may harm kidney function.

Quit Smoking

Smoking has been linked to a higher risk of kidney disease and can contribute to the progression of existing renal conditions. Quitting smoking is a positive step toward improving overall kidney health and preserving GFR.

Limit Alcohol Intake

Excessive alcohol consumption can contribute to high blood pressure and liver disease, both of which can impact kidney function. Moderating alcohol intake supports overall health and kidney function.

Maintain a Healthy Weight

Being overweight is associated with an increased risk of kidney disease. Adopting a healthy lifestyle that includes a balanced diet and regular physical activity can help achieve and maintain a healthy weight, reducing the risk of kidney-related complications.

Regular Health Check-ups

Regular monitoring of kidney function through routine health check-ups, including blood tests to assess GFR and other kidney markers, allows for early detection of potential issues. Timely intervention can help manage and slow the progression of kidney disease.

Personalized Nutrition: How Your Genes Affect Vitamin K Levels

Aira on December 1, 2023

Overview

What is Vitamin K?

Ever heard your parents tell you to eat your fruits and veggies for more Vitamin K? If not, you’re not the only one. Vitamin K is not as popular among the necessary vitamins to get but it is no less important than Vitamins A, B, and C when it comes to keeping the body healthy.

Vitamin K is a fat-soluble vitamin that plays a crucial role in blood clotting, bone metabolism, and cardiovascular health. It exists in two primary forms: K1 (phylloquinone) and K2 (menaquinone). Phylloquinone is found in green leafy vegetables, while bacteria synthesize menaquinone in the human gut, and is also present in fermented foods.

The main function of vitamin K is to activate proteins involved in blood clotting, such as prothrombin. Without sufficient vitamin K, the blood clotting process would be impaired, leading to increased bleeding tendencies. Vitamin K also contributes to bone health by regulating calcium within the bones and arteries. It helps to prevent the calcification of arteries and soft tissues, reducing the risk of cardiovascular diseases.

Vitamin K deficiency is relatively rare, but it can occur in individuals with malabsorption issues, certain medical conditions, or those taking medications that interfere with vitamin K metabolism. Symptoms of deficiency include easy bruising, bleeding, and impaired bone health. In some cases, supplements may be recommended, particularly for individuals with specific health conditions or those taking medications that interfere with vitamin K absorption.

Where Can You Find Vitamin K?

There are many sources of Vitamin K. Vitamin K1, also known as phylloquinone, is abundant in green leafy vegetables such as kale, spinach, broccoli, and lettuce. These vegetables are potent sources that contribute significantly to daily vitamin K intake.

Vitamin K2, or menaquinone, is found in fermented foods like kefir and natto (fermented soybeans), cheeses, and certain other animal products. The human gut microbiota also synthesizes a portion of vitamin K2, enhancing overall availability.

To maintain optimal vitamin K levels, incorporating a diverse range of foods into the diet is crucial. As with any nutrient, balance is key, and consulting with a healthcare professional can help tailor dietary choices to individual needs, ensuring adequate vitamin K intake for blood clotting, bone health, and overall well-being.

What Can Affect Vitamin K Levels?

Diet, problems with absorption, interactions between medications, and gastrointestinal health can all affect vitamin K levels. Optimal vitamin K levels are supported by a diet high in fermented foods, green leafy vegetables, and sufficient gut flora. Functional Vitamin K deficits may result from some medicines that interfere with its activity, such as blood thinners.

Vitamin K absorption may be impacted by conditions that influence fat absorption, such as inflammatory bowel disorders or celiac disease. Maintaining healthy bones, appropriate blood coagulation, and general vitamin K-dependent bodily processes all depend on these variables.

Genetic Factors

The way a person gets this vital nutrient is influenced by genetic factors associated with vitamin K metabolism. Although this area of study is still developing, some genetic variants have been shown to affect the way the body metabolizes and uses vitamin K.

A more complete picture of the effects of individual genetic variants on vitamin K metabolism is likely to emerge as genetic research progresses. With the ability to customize interventions based on each person’s distinct genetic composition, this knowledge could advance precision medicine and lead to better health outcomes.

VKORC1 Gene

Vitamin K is crucial for bone health, and its processing depends on a gene called VKORC1. One study shows that those with a specific VKORC1 variation (9041 GG and GA) were more likely to have low bone density, suggesting a higher risk for them. The study indicates that a genetic difference in the VKORC1 gene may be associated with low bone density, possibly influencing osteoporosis.

GGCX Gene

Another significant genetic component is the GGCX gene, which encodes an enzyme that activates vitamin K-dependent proteins. Changes in GGCX, such as those associated with the SNP rs10187424, may have an impact on how well this activation mechanism works, which may have an impact on bone metabolism and blood coagulation.

CYP4F2 Gene

The CYP4F2 gene has been associated with vitamin K metabolism. This gene codes for an enzyme involved in the breakdown of vitamin K. Polymorphisms in CYP4F2 may influence how quickly the body clears vitamin K, impacting its availability for various biological functions.

Understanding one’s genetic predisposition can have implications for personalized nutrition and healthcare. Individuals with certain genetic variations may benefit from tailored dietary approaches, supplementation, or adjusted medication regimens to optimize their vitamin K status.

Environmental Factors

Genetic factors represent just one aspect of the complex interplay influencing active vitamin K levels. Environmental factors, overall health, and lifestyle choices also play significant roles.

Diet

Variety of Foods: A diverse diet rich in green leafy vegetables, such as kale, spinach, and broccoli, provides ample vitamin K1. Cheese, meat, and fermented foods like natto or sauerkraut contribute to vitamin K2. A balanced and varied diet helps ensure sufficient vitamin K intake.

Gut Health

Microbiota: The gut microbiota plays a crucial role in synthesizing vitamin K2. Individuals with imbalances in gut bacteria or those taking antibiotics that disrupt the microbiota may experience altered vitamin K metabolism.

Medications

Antibiotics: Certain antibiotics can affect the gut microbiota, potentially impacting vitamin K synthesis. Individuals on prolonged or frequent antibiotic courses may need to monitor their vitamin K levels.

Liver Function

Liver Diseases: Since the liver is crucial for synthesizing clotting factors dependent on vitamin K, liver diseases can affect vitamin K metabolism. Individuals with liver disorders may have altered vitamin K levels.

Age and Life Stage

Infants: Newborns may have lower vitamin K levels, as they are born with limited stores and their gut microbiota is still developing. Vitamin K supplementation is often recommended for newborns to prevent bleeding disorders.

Lifestyle Choices

Alcohol Consumption: Excessive alcohol intake can impact liver function, potentially affecting the synthesis of vitamin K-dependent proteins involved in blood clotting.

Weight Loss Surgeries

Bariatric Surgery: Procedures that involve the removal or bypass of parts of the gastrointestinal tract can lead to malabsorption of fat-soluble vitamins, including vitamin K.

Smoking

Tobacco Use: Some studies suggest that smoking may be associated with lower vitamin K levels. The exact mechanisms are not fully understood, but smoking-related oxidative stress could be a contributing factor.

Physical Activity

Exercise: Regular physical activity has been associated with improved vitamin K status. However, extreme exercise or training may increase the risk of vitamin K deficiency due to increased metabolic demands.

Understanding and addressing these environmental factors are crucial for maintaining optimal vitamin K levels. Individuals with specific health conditions, those taking medications, or those undergoing significant lifestyle changes should consult healthcare professionals to assess and manage their vitamin K status effectively. Regular monitoring and adjustments to dietary habits or supplementation may be recommended based on individual needs and circumstances.

Why is Vitamin K Given to Newborn Babies?

Vitamin K is routinely administered to newborn babies shortly after birth to prevent a rare but potentially serious condition known as Vitamin K Deficiency Bleeding (VKDB) or Hemorrhagic Disease of the Newborn (HDN). This practice has become a standard part of newborn care in many countries.

Newborns are born with limited stores of vitamin K, and their ability to produce it through their gut microbiota is not fully developed in the early days of life. Vitamin K is essential for the synthesis of clotting factors in the liver. Without sufficient vitamin K, newborns are at risk of bleeding disorders, which can lead to serious complications, including internal bleeding in the brain.

The most severe form of VKDB, known as early onset VKDB, can occur within the first 24 hours to the first week of life. Since newborns may not have enough vitamin K to prevent bleeding during this critical period, a single intramuscular vitamin K injection is commonly administered shortly after birth. In some cases, oral vitamin K may be given as an alternative.

This preventive measure has proven highly effective in reducing the incidence of VKDB and its associated complications. While VKDB is rare, the potential consequences underscore the importance of this routine administration of vitamin K, ensuring the newborn’s blood-clotting system is adequately supported during the vulnerable early days of life.

What Happens if You Have Vitamin K Deficiency?

Vitamin K deficiency can lead to impaired blood clotting, potentially resulting in excessive bleeding and bruising. Since vitamin K is essential for the synthesis of clotting factors in the liver, a deficiency can compromise the body’s ability to form blood clots effectively. This may manifest as easy bruising, prolonged bleeding from wounds, or, in severe cases, spontaneous bleeding.

Vitamin K is also involved in regulating calcium in the bones and arteries. A deficiency may contribute to abnormal calcium deposition in soft tissues, potentially impacting bone health and cardiovascular function. Individuals experiencing symptoms of vitamin K deficiency should seek medical attention for proper diagnosis and intervention.

What is the Suggested Daily Intake of Vitamin K?

The recommended daily intake of vitamin K can vary based on factors such as age, sex, and life stage. Generally, the Adequate Intake (AI) levels for vitamin K established by health authorities are as follows:

Infants

0 to 6 months: 2 micrograms (mcg) per day
7 to 12 months: 2.5 mcg per day

Children

1 to 3 years: 30 mcg per day
4 to 8 years: 55 mcg per day
9 to 13 years: 60 mcg per day

Adolescents and Adults

Males 14 to 18 years: 75 mcg per day
Females 14 to 18 years: 75 mcg per day
Males 19 years and older: 120 mcg per day
Females 19 years and older: 90 mcg per day

Pregnant and Breastfeeding Women

Pregnant females 14 to 18 years: 75 mcg per day
Pregnant females 19 years and older: 90 mcg per day
Breastfeeding females 14 to 18 years: 75 mcg per day
Breastfeeding females 19 years and older: 90 mcg per day

These recommendations are based on maintaining adequate blood clotting and bone health. It’s important to note that individual needs may vary, and factors such as medical conditions, medications, and diet can influence vitamin K requirements.

Individuals with specific health concerns should consult healthcare professionals for personalized guidance on meeting their vitamin K needs.

Ways to Maintain Vitamin K Levels

Maintaining adequate vitamin K levels is crucial for overall health, especially for proper blood clotting and bone metabolism.

Dietary Sources

Proteinuria: Unraveling the Clues in Your Urine

Aira on November 15, 2023

What is Proteinuria?

Proteinuria may seem like a complex term, but it can be simplified as the presence of excessive protein in urine. It can also indicate potential kidney issues or broader health concerns.

Proteins are fundamental building blocks in the body, performing essential functions such as muscle and bone development, regulating blood fluid levels, defending against infections, and aiding in tissue repair. Ideally, these proteins should remain in the bloodstream. When they appear in urine, it could signify a problem, potentially affecting your overall health.

Proteinuria can arise from various factors, ranging from temporary and benign situations like dehydration or intense physical activity to more severe underlying conditions like kidney diseases or immune disorders. Once diagnosed through medical testing, a treatment plan can be tailored to manage proteinuria effectively, ensuring your health remains a top priority.

Understanding proteinuria is a crucial first step in maintaining your well-being.

What Causes Proteinuria?

Proteinuria stems from a complex interplay of genetic and non-genetic influences. Genetic factors encompass hereditary aspects and variations in specific genes, while non-genetic factors involve environmental elements and various external triggers. These factors collectively contribute to the development of proteinuria and its potential health implications.

Genetic Factors

Genetic factors play a relatively rare but significant role in causing proteinuria, affecting children and adults. To shed light on this complex aspect of proteinuria, researchers have made noteworthy progress by delving into the genetic and molecular underpinnings of specific syndromic and nonsyndromic proteinuric disorders. These disorders stem from mutations in genes responsible for the structural components of the glomerular filtration barrier, which plays a pivotal role in filtering the blood and retaining essential proteins.

LRP2 and CUBN

Genetic diversity has a profound influence on urinary biomarkers and their role in diagnosing kidney, urinary tract, and metabolic diseases. In a comprehensive study involving 150,274 Icelanders and their urine dipstick measurements, 20 association signals emerged, shedding light on how genetic variants impact clinical entities defined by the urine dipstick.

The study unveiled two variants associated with proteinuria, located in LRP2 and CUBN, which encode megalin and cubilin, key co-transporters responsible for the uptake of proteins in the proximal tubules of the kidneys.

These novel findings emphasize the impact of genetic factors on urinary biomarkers and further underscore the significance of genetic diversity in understanding conditions affecting the kidneys and urinary tract. The study’s results unveil the complex interplay of genetic diversity in influencing urinary biomarkers, offering valuable insights into kidney and urinary tract health.

NR3C2 and COL4A4

In a comprehensive genome-wide association study involving 382,500 participants from the UK Biobank, researchers identified genetic variants associated with albuminuria, a key marker of kidney health. Notably, the study revealed a wealth of genetic insights, uncovering 33 genome-wide significant loci, including 32 novel and one previously reported association at the CUBN locus, further enhancing our understanding of kidney-related conditions.

Among the newly discovered associations, the NR3C2 and COL4A4 loci have potential clinical significance. The NR3C2 gene encodes the mineralocorticoid receptor, and it’s worth noting that mineralocorticoid receptor antagonists like spironolactone and eplerenone have been shown to reduce albuminuria when added to other antihypertensive medications. This finding highlights the potential for targeted therapies in managing albuminuria.

Moreover, mutations in the COL4A4 gene and its neighboring counterpart, COL4A3, can lead to autosomal Alport syndrome, a condition characterized by kidney disease, which may include proteinuria. These genetic revelations provide valuable insights into the intricate genetic factors influencing kidney health, paving the way for more tailored diagnostic and therapeutic approaches.

Non-Genetic (Environmental) Factors

In addition to genetic factors, non-genetic or environmental factors contribute significantly to proteinuria. Various conditions, such as infections, lifestyle choices, and environmental exposures, can trigger proteinuria as a response to external influences. Investigating these non-genetic factors helps us understand how external elements contribute to proteinuria and the measures that can be taken to prevent or effectively manage it.

Benign Causes of Proteinuria

Among the diverse factors influencing proteinuria, there are benign causes that do not pose a significant threat to overall health and are usually reversible once the underlying issues are resolved. Such factors include acute illnesses, physical exertion, and other benign triggers. The following are some common benign causes of proteinuria:

Fever
Acute illness
Exercise/intense physical activity
Orthostatic proteinuria
Dehydration
Emotional stress
Heart injury
Inflammatory process

Transient Proteinuria

Transient proteinuria is a temporary condition characterized by elevated protein levels in the urine. This proteinuria typically occurs due to benign and reversible factors such as:

Urinary tract infection
Orthostatic proteinuria (occurs after a patient has been upright for an extended period. It is typically absent in early morning urine and is more common in individuals under 30 years of age)
Fever
Heavy exercise
Vaginal mucus
Pregnancy

Persistent Proteinuria

Persistent proteinuria, on the other hand, is a condition where elevated protein levels in the urine persist over time and may signify underlying renal or systemic health issues. Here are factors that contribute to the development of persistent proteinuria:

Primary Renal Disease (including glomerular conditions such as glomerulonephritis, as well as tubular disorders)
Secondary Renal Disease (including diabetes mellitus, connective tissue diseases, vasculitis, amyloidosis, and myeloma)
Heart Conditions
Hypertension

Is Proteinuria Serious?

Proteinuria is a common finding in urinalysis and can serve as an indicator of various medical conditions, with implications that range from benign to more serious. Some cases of proteinuria, such as orthostatic proteinuria, are relatively benign and may be associated with a favorable prognosis. However, other instances of proteinuria can be indicative of more serious underlying health issues, such as glomerular disease or multiple myeloma.

The seriousness of proteinuria often depends on its root causes and the amount of protein excreted in the urine. Several factors can contribute to increased protein levels in the urine, including changes in glomerular filtration, pathological alterations of the glomeruli, and toxic damage that increases urinary excretion of all proteins.

Since proteinuria may indicate severe renal conditions, further evaluation is crucial for diagnosis and proper medical management. It is a significant marker for potential underlying health issues needing attention and diagnosis.

What are the Symptoms of Proteinuria?

Proteinuria can manifest through various symptoms. It’s important to note that in the early stages, proteinuria may not cause visible symptoms, making regular check-ups and urinalysis crucial for early detection. However, when symptoms do occur, they can include:

Foamy Urine

One common symptom of proteinuria is the production of foamy or frothy urine. This occurs because the excess protein in the urine can become bubbly when it flows into the toilet bowl.

Swelling of the Hands, Feet, Face, and/or Abdomen

Another noticeable symptom can be swelling, also known as edema. Excess protein leaking into the urine means there is less protein in the blood to keep fluid in the blood vessels. As a result, fluid can accumulate in tissues, leading to swelling, particularly in the hands, feet, face, and abdomen.

It’s essential to be aware of these symptoms, particularly if they persist or worsen over time. Detecting and addressing proteinuria in its early stages can help prevent or manage underlying health conditions and minimize potential complications. Regular medical check-ups and urinalysis are key components of proactive healthcare, allowing for the timely evaluation of proteinuria and its associated symptoms.

Management and Considerations for Proteinuria

Proteinuria requires a comprehensive approach to its management. Treatment strategies aim at addressing the underlying cause while minimizing proteinuria levels, particularly albuminuria. Various treatment modalities have been established to manage proteinuria effectively. These treatments encompass:

Drugs Targeting the Renin-Angiotensin-Aldosterone System

In adults with over 300 mg/24 hours of persistent proteinuria, the 2013 Kidney Disease Improving Global Outcomes (KDIGO) guideline strongly recommends using ACE inhibitors or angiotensin receptor antagonists (ARB). These medications, such as ACE inhibitors, have demonstrated their efficacy in reducing proteinuria in diabetic and nondiabetic patients. Beyond their impact on proteinuria, these drugs also lower the risk of renal disease progression, reducing the need for renal replacement therapy. Achieving a 50% reduction in albuminuria within the first six months to a year has been linked to a similar decrease in the risk of renal disease progression.

Diuretics and Aldosterone Antagonists

Moderate to severe proteinuria often results in fluid overload, requiring diuretic therapy and dietary salt restriction. Aldosterone antagonists have shown benefits in proteinuria management, but close monitoring for side effects, including hyperkalemia, is crucial. Combination therapy of ACE inhibitors with aldosterone antagonists may be considered, bearing in mind potential risks and benefits, particularly for patients with heart failure.

Calcium Channel Blockers

Non-dihydropyridine calcium channel blockers (NDCCBs), such as diltiazem and verapamil, have been found to reduce proteinuria more effectively than dihydropyridine calcium channel blockers (DCCBs). Novel NDCCBs, including efonidipine and benedipine, combined with ARBs, have shown promise in reducing proteinuria.

While these treatment options are instrumental in managing proteinuria, therapeutic decisions should be tailored to individual patients, considering their specific conditions and responses to treatment. Additionally, the assessment of combination therapies and potential side effects must be conducted on a case-by-case basis to ensure the most suitable approach.

Differential Diagnosis, Prognosis, Complications, and Consultations

The presence of proteinuria requires a thorough evaluation, considering conditions such as diabetic nephropathy, orthostatic proteinuria, and infections.

Prognosis in proteinuria patients hinges on early recognition and management, offering insights into potential outcomes for conditions such as IgA nephropathy and chronic kidney disease.

Proteinuria elevates the risk of complications such as heart disease, kidney disease progression, and the need for renal replacement therapy, with severity tied to its degree and duration.

Collaboration with specialists, regular monitoring, and holistic management are vital in addressing proteinuria and associated complications, especially in patients with hypertension and diabetes.

Visual Acuity: Seeing Clearly Through Science and Genetics

Aira on November 15, 2023

What is Visual Acuity?

Visual acuity measures how well a person’s eyes can discern fine details, often referred to as having “20/20” vision. It is akin to the ability to read small text, recognize distant faces, or perceive intricate patterns. Visual acuity is assessed through various tests, commonly involving reading letters or symbols on a chart.

It is influenced by inherent eye factors like light entry and optical quality, as well as external factors such as lighting, corrective lenses, and object contrast. It also acts as an objective indicator of an individual’s capacity to perceive small details in their visual surroundings.

Factors influencing visual acuity encompass the eye’s optical properties and the interplay of external elements that collectively impact the clarity with which these details can be seen.

Measuring Visual Acuity

Measuring visual acuity (VA) is a crucial process in evaluating an individual’s ability to perceive fine details in their visual field. It helps establish a baseline recording of VA, aids in diagnosing eye diseases or refractive errors, assesses any vision changes, and even measures the outcomes of surgeries like cataract removal. The procedure involves assessing one eye at a time to ensure accuracy.

To carry out VA testing, you’ll need specific equipment, including a multi-letter Snellen or E chart, a plain occluder (like a card or tissue), a pinhole occluder, a torch or flashlight, and the patient’s documentation. It’s essential to have good natural light or illumination on the chart, providing the patient with the best chance to see and read the chart. The patient is positioned at a distance of 6 meters from the chart, and one eye is tested at a time, first without any spectacles if worn.

Record the smallest readable line, e.g., 6/18, with the upper number indicating chart distance (6 meters) and the lower number representing a ‘normal’ eye’s distance. Incomplete lines can be added to the last complete one. After testing without correction, assess VA with current distance spectacles, recording results for each eye separately.

Use a pinhole occluder if the best vision (6/6) isn’t achieved to identify possible causes of visual impairment, such as corneal irregularities, lens issues, or refractive errors that may require correction.

The same procedure is then repeated for the other eye, and the summary of VA for both eyes is recorded in the patient’s notes. It’s important to ensure that VA testing is done accurately, particularly when dealing with children, as incorrect results can lead to inappropriate decisions and management.

Genetics of Visual Acuity

The genetics of visual acuity is an intricate area of study. In the pursuit of understanding the genetic underpinnings of visual acuity, a Genome-Wide Association Study (GWAS) was conducted. This study, involving a large cohort of individuals, revealed significant genetic associations with visual acuity.

NPLOC4 Locus

Twelve Single Nucleotide Polymorphisms (SNPs) located at the NPLOC4 locus on chromosome 17 reached genome-wide significance. The strongest association was found for rs11656126, with each copy of the major allele shifting an individual towards better visual acuity. This discovery suggests that genetic variations at the NPLOC4 locus play a significant role in regulating visual acuity.

Other Loci

In a targeted replication analysis of SNPs derived from previous literature, two genomic loci reached Bonferroni-corrected significance. The first locus included SNPs from the NPLOC4 and the PDE6G gene and was associated with both reduced refractive error and visual acuity. The second locus spanned an intergenic region upstream of PRSS56, previously associated with myopia and refractive error.

Genes associated with Primary Open-Angle Glaucoma (POAG)

Several Single Nucleotide Polymorphisms (SNPs) have been associated with Primary Open-Angle Glaucoma (POAG), a condition affecting vision. Here are some notable SNPs linked to POAG:

APOE gene (rs449647)

A study involving five different research efforts found a significant association between this SNP and POAG. Apolipoprotein E (APOE) is a member of the lipoprotein class responsible for regulating lipid metabolism in the body. Numerous studies have indicated an association between apolipoprotein E and neurodegenerative diseases, including Alzheimer’s disease and glaucoma.

PLXDC2 gene (rs7081455)

This SNP was reported in three studies, and a significant association was found in the allelic model. Plexin domain-containing 2 (PLXDC2) is a transmembrane protein on the cell surface that acts as a receptor for pigment epithelium–derived factor (PEDF). The presence of a genetic variant in PLXDC2 might result in elevated intraocular pressure.

TMCO1 gene (rs4656461)

This SNP has been studied in four different investigations and was found to have a significant association with POAG in the allelic model. The TMCO1 gene produces a transmembrane protein that is capable of localizing to various cell components such as the Golgi apparatus, endoplasmic reticulum, or mitochondria in different cell types. It is suggested to play a role in apoptosis, the process of programmed cell death.

These SNPs provide valuable insights into the genetic aspects of visual acuity and the risk of developing POAG. Understanding the genetic underpinnings of eye diseases like POAG is crucial in identifying at-risk individuals and developing targeted treatments to preserve and enhance visual acuity.

Non-genetic (Environmental) Factors Affecting Visual Acuity

How well a person can see is influenced by various factors beyond their genes. While genetics play a significant role in shaping our visual potential, several non-genetic factors also come into play, impacting the clarity and sharpness of our vision. Knowing what these non-genetic factors are, is essential to appreciate the full spectrum of influences on visual acuity.

Refractive Error

One significant factor is refractive error. It’s when a person’s eyes don’t focus properly. Myopia, or short-sightedness, means the image focuses in front of the retina, while hyperopia, or long-sightedness, means the image focuses behind the retina. Both of these conditions can result in blurriness.

Pupil Size

The size of the eye’s pupil is important, too. The pupil controls how much light enters the eye. Larger pupils allow more light in, which can be great for brightness but might introduce problems with clear vision. Smaller pupils reduce these issues but can limit the amount of light reaching the retina. So, a medium-sized pupil strikes a balance for good vision.

Illumination

The level of brightness in the environment also plays a role. Think of it like adjusting the brightness on a TV. In very bright conditions, our eyes can see details well. In lower light, only specific parts of our eyes are active, leading to less sharp vision. It’s about finding the right balance.

Time of Exposure of the Target

When individuals try to see something, the time they spend looking at it matters. It’s not just about the amount of light. For example, when looking at a small, bright dot, it’s more about the light itself. But when looking at a line, the longer it’s observed, the clearer it becomes. It’s a bit complex to explain.

Area of the Retina Stimulated

The center of vision, where individuals look directly, is very sharp. But as they look away from the center, things get blurrier. It’s like having a “sweet spot” in their vision. If they move too far from it, things aren’t as clear.

State of Adaptation of the Eye

Our eyes adapt to different light levels. In bright light, our vision is at its best. In the dark, not so much. Special cells help with this adaptation affecting our ability to see clearly.

Eye Movement

Even when individuals think their eyes are still, they’re making tiny movements. This affects how they see things, making them seem a bit fuzzy.

All these factors combine to determine how well people see. It’s a mix of various elements, with genetics playing a part, but these non-genetic factors are just as crucial. Understanding them can help us take care of our vision and see the world with more clarity.

Correcting Visual Acuity Problems

Visual acuity is a vital aspect of human vision, enabling individuals to achieve 20/20 clarity, and allowing them to discern fine details and navigate the world with precision.

It is pivotal in their ability to read small text, recognize distant faces, and appreciate intricate patterns. However, in the pursuit of perfecting the 20/20 vision, challenges arise, and various correction methods have been explored.

To enhance visual acuity, especially in cases of reduced clarity, several correction methods have been investigated. These methods aim to ultimately improve the overall visual experience.

Vision Correction Lenses

Vision correction methods encompass a range of options, including single-vision lenses, bifocals, progressive addition lenses (PALs), and contact lenses.

Single-vision lenses are commonly prescribed for vision issues, but their effectiveness varies based on individual needs. Bifocals and progressive addition lenses have shown promise in enhancing visual acuity, although further research is ongoing.

Contact lenses, particularly rigid gas permeable (RGP) lenses, can provide clear vision, but the potential reversibility of their effects requires further optimization through research.

Under-Correction of Visual Acuity

Some clinicians recommend under-correction as a strategy to achieve better clarity. Research suggests that under-corrected lenses may not be as effective in enhancing visual acuity as fully corrected ones. The choice between these approaches requires careful consideration and further investigation.

Pharmaceutical Agents

Atropine and pirenzepine, pharmaceutical agents, have demonstrated potential in enhancing visual acuity. Recent studies suggest their ability to significantly improve clarity when combined with specific optical interventions. However, the long-term impact and potential side effects require further investigation.

LASIK (Laser-Assisted In Situ Keratomileusis)

This surgery is a highly advanced and widely practiced medical procedure designed to enhance visual acuity by reshaping the cornea. The cornea, a clear, domed structure on the front surface of the eye, plays a crucial role in focusing light onto the retina, which then transmits visual information to the brain. The shape of the cornea directly affects how light is refracted and where it converges on the retina.

LASIK surgery is primarily employed to correct common refractive errors, including myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. By reshaping the cornea’s curvature, LASIK aims to enable the eye to focus light precisely on the retina, resulting in improved visual clarity.

How to Maintain Good Visual Acuity

Ensuring that your vision remains sharp and your eyes stay healthy is essential for a high-quality life. Here are some practical guidelines to preserve visual acuity and keep your eyes in optimal condition:

Manage Blood Sugar Levels

If you have diabetes, maintaining healthy blood sugar levels is paramount to preventing diabetes-related blindness. Consult your healthcare team to set and achieve goals for managing blood sugar, blood pressure, and cholesterol levels, often called the ABCs of diabetes.

Maintain a Healthy Weight

Staying at a healthy weight is not only beneficial for your overall health but also for your eye health. Obesity increases the risk of systemic conditions, such as diabetic eye disease or glaucoma, which can lead to vision loss.

Wear Protective Eyewear

Whenever you engage in sports or activities at home that pose a risk to your eyes, make sure to wear protective eyewear. This includes safety glasses, goggles, safety shields, and eye guards designed for specific activities. These protective eyewear options typically use exceptionally durable polycarbonate lenses.

Avoid Smoking

Smoking is detrimental to both your overall health and your eyes. It has been linked to an increased risk of age-related macular degeneration, cataracts, and optic nerve damage, which can ultimately lead to blindness.

Invest in Quality Sunglasses

Sunglasses serve as a fashionable accessory, but their primary role is to shield your eyes from harmful ultraviolet (UV) rays. Look for sunglasses that block out 99 to 100 percent of both UV-A and UV-B radiation for maximum protection.

Give Your Eyes a Break

If you find yourself spending extended periods focusing on a screen or any one task, remember to take regular breaks to reduce eyestrain. The 20-20-20 rule is a helpful guideline: every 20 minutes, shift your focus to something approximately 20 feet away from you for at least 20 seconds.

Maintain Good Hygiene for Contact Lenses

If you wear contact lenses, proper hygiene is crucial. Always wash your hands thoroughly before inserting or removing your lenses. Follow the recommended disinfection and replacement protocols to avoid the risk of eye infections.

Prioritize Workplace Eye Safety

If your job requires protective eyewear, make wearing the appropriate eyewear a routine part of your workday. Encourage your coworkers to do the same to ensure a safe work environment.

Consume a Balanced Diet

Eating a diet rich in fruits and vegetables, especially dark leafy greens like spinach and kale, is essential for eye health. Additionally, incorporating omega-3 fatty acids found in fish like salmon, tuna, and halibut can provide significant benefits for your eyes.

Schedule Comprehensive Eye Exams

Even if your vision seems fine, regular comprehensive dilated eye exams conducted by an eye care professional are crucial. These exams are the only way to detect common vision problems, and they help in the early identification of eye diseases such as glaucoma, diabetic eye disease, and age-related macular degeneration.

By following these simple yet effective guidelines, you can maintain good visual acuity and protect your eyes, ultimately ensuring a lifetime of clear and healthy vision.

Summary

Visual acuity measures a person’s ability to discern fine details and is often described as a “20/20” vision.
Comprehensive dilated eye exams are necessary to assess visual acuity, diagnose eye diseases, and detect vision changes.
Genetic factors, including Single Nucleotide Polymorphisms (SNPs), influence visual acuity, and SNPs are associated with conditions like Primary Open-Angle Glaucoma (POAG).
Non-genetic factors, such as refractive errors, pupil size, illumination, time of exposure, and eye movement, also affect visual acuity.
Correction methods include single vision lenses, under-correction, bifocals, progressive addition lenses (PALs), contact lenses, pharmaceutical agents, and LASIK surgery.
To maintain good visual acuity, manage diabetes (if relevant), maintain a healthy weight, wear protective eyewear, avoid smoking, use UV-protective sunglasses, take breaks to reduce eyestrain, practice proper contact lens hygiene, and eat a balanced diet.
