Effect of Adding Folic Acid on Lipid Parameters in Population With Dyslipidemias

Study Overview
=================
Brief Summary
-----------------
Background: Homocysteinemia is associated with increased risk of stroke, dyslipidemias, dementia, peripheral vascular disease and coronary artery disease. folic acid is involved in the metabolism of homocysteine. Folic acid supplementation helps to reduce homocysteine levels and lowering of homocysteine may cause improvement in serum lipid profile. In this study we will assess the effect of folic acid supplementation for 6 weeks, on lipid parameter in patients who have dyslipidemia. Methods: It is a placebo controlled randomized trial, consisting of two groups, Group A (n=34) and Group B (n=34). Group A (intervention group) will be given Folic acid supplements and the second group will be given a placebo. After 6 weeks changes in lipid parameters, will be measured in both groups. Discussion: Folic acid is water soluble vitamin also known as vitamin B-9. Folic acid works as co-factor in many biochemical enzymatic reactions. Homocysteine metabolism also requires folic acid, homocysteinemia may worsen renal function, lipid parameter, accelerate atherosclerosis, angiopathies, and progression of dementia, also increase the risk of stroke and coronary artery disease. In this study, Group A (treatment Group) will be given folic acid supplementation while the Group B (Placebo Group) will be given placebo and at the end of 6 weeks, HDL, LDL, Triglycerides and serum cholesterol levels will be measured and compared with the pre-treatment levels. If Post-treatment group shows significant decrease in serum LDL, total cholesterol, triglycerides and increase in HDL then Folic acid supplementation may be routinely recommended for patient with dyslipidemias.

Detailed Description
-----------------
Hyperlipidemia, increases the risk of stroke, hypertension, coronary artery disease and other associated disorders. World-wide about one-third of coronary artery disease is attributed high cholesterol. Overall it has been estimated that elevated blood cholesterol causes 26 million deaths (4.5% of the total deaths) world-wide. Hyperlipidemias is a major cause of morbidity in both developed and developing countries as a risk factor for stroke and coronary artery disease. The prevalence of raised total cholesterol increased noticeably according to the income level of the country. In low income countries around a quarter of adults had raised total cholesterol, in lower middle income countries this rose to around a third of the population for both sexes. In high-income countries, over 50% of adults had raised total cholesterol; more than double the level of the low-income countries. Homocysteine, on the other hand, is a sulfur amino acid, which is metabolized by two pathways, either it is re-methylated to methionine or it undergoes trans-sulfuration to cystathionine which is eventually converted into cysteine, an amino acid. Folic acid is involved in remethylation of homocysteine to methionine. Thus, folic acid supplementation may enhance the metabolism of homocysteine level and thereby may decrease its level in blood. Homocysteine in blood is termed as homocysteinemia. Homocysteinemia is associated with dyslipidemias, increased risk of atherosclerosis, micro-angiopathies, coronary artery disease, stroke, dementia and also found to be associated with suppressed immunity. Supplementation with folic acid may lower homocysteine level by accelerating its metabolism to methionine. In this study investigators will be assessing the effect of folate supplementation on the lipid profile, particularly on the blood levels of HDL, LDL, Triglycerides and total cholesterol. The HDL has cardio-protective effect, while on the other hand, the higher level of LDL, total cholesterol and triglycerides may accelerate atherosclerosis, angiopathies and increases the risk of stroke and heart diseases. Research question: Does addition of folic acid supplementation decrease LDL, total cholesterol, triglycerides and increase HDL in patients with dyslipidemias. OBJECTIVE: To assess the effect of folic acid supplementation on HDL, LDL, total cholesterol and triglycerides in patients with dyslipidemias. HYPOTHESIS Addition of folic acid supplementation will improve lipid parameters (HDL, total cholesterol, triglycerides & LDL) in patients with dyslipidemias.
