Serum 25(OH)D Concentration and Cardiovascular Disease Risk Markers Among Middle-Aged Healthy and Type 2 Diabetic Subjects

Abstract

AbstractVitamin D deficiency is a major widespread health concern and is linked to a high risk of cardiovascular disease (CVD). Thus, we have investigated the association of vitamin D with various CVD risk markers. The present study comprises 90 control and 90 type 2 diabetes mellitus (T2DM) subjects of both sexes (age range, 30–50 years). The 25 hydroxyvitamin D [25(OH)D] and CVD risk markers including high sensitive C-reactive protein (hs-CRP), monocyte chemoattractant protein-1 (MCP-1), intact parathyroid hormone (I-PTH), fibroblast growth factor (FGF)-23, erythrocyte sedimentation rate (ESR), and fibrinogen were measured by using standard assays. Blood viscosity and atherogenic index of plasma calculated using standard formulae. The ten-year cardiovascular risk was assessed using the Framingham risk score (FRS). 25(OH)D, hs-CRP, MCP-1, FGF-23, ESR, fibrinogen, atherogenic index of plasma and FRS were significantly different between control and T2DM groups (p<0.05). 25(OH)D showed a significant negative correlation with MCP-1, ESR, blood viscosity, atherogenic index of plasma and FRS among total study subjects. Further, logistics regression analysis showed an association of 25(OH)D with MCP-1, hematocrit, fibrinogen, and blood viscosity. The association between 25(OH)D and various CVD risk markers suggests that 25(OH)D might help in the prediction of CVD risk.
