Supplementation of Water-Soluble Vitamins Reduces Hyperhomocysteinemia, Insulin Resistance, and High-Sensitivity C-reactive Protein in Prehypertension Subjects.

Abstract

Prehypertensives are at higher risk of developing cardiovascular diseases. Hyperhomocysteinemia, insulin resistance, and increased high-sensitivity C-reactive protein (hs-CRP) are independent risk factors for the development of cardiovascular complications. In prehypertensives, specific therapeutic approaches can be implemented at the earliest to prevent the onset of overt hypertension. So the present study was performedto study the effect of supplementation of water-soluble vitamins on cardiovascular risk factors like homocysteine, insulin resistance, and C-reactive protein in prehypertensive subjects. Sixty prehypertensive subjects were recruited into the study based on inclusion and exclusion criteria and randomized into two groups of 30 each. One group was given a placebo and the other was given water-soluble vitamins for four months. Serum homocysteine, insulin, homeostatic model assessment of insulin resistance (HOMA-IR), and hs-CRP were assayed. After four months of treatment with water-soluble vitamins, there was a significant decrease in levels of serum homocysteine, hs-CRP, and HOMA-IR when compared to placebo treatment. After four months of treatment, there was a significant decrease in the levels of hs-CRP, homocysteine, and HOMA-IR in groups treated with water-soluble vitamins compared to the basal levels. In subjects with prehypertension, supplementation of water-soluble vitamins decreases the level of homocysteine, insulin resistance, and hs-CRP.
