This study aims to assess vitamin D deficiency-induced dyslipidemia and cardiovascular disease (CVD) risk in poor glycemic control among type 2 diabetes mellitus (T2DM) patients. This study was carried out among 455 T2DM patients involving poor glycemic control (n = 247) and good glycemic control (n = 208). Fasting plasma glucose (FPG) and HbA1c were measured to assess glycemic control. Cardiac risk ratio, atherogenic index plasma, and atherogenic coefficient were calculated to assess and compare the CVD risk in different groups. Patients with poor control had a significantly higher level of total cholesterol (TC), triglyceride (TG), and non-high-density lipoprotein lipase cholesterol (non-HDL-C), atherogenic variables, and lower level of high-density lipoprotein lipase cholesterol (HDL-C) as compared to patients with good glycemic control. We also observed significant negative correlation of vitamin D with lipid markers and atherogenic variables in poor glycemic control diabetic population. The serum vitamin D levels were inversely associated with HbA1c, FPG, TG, TC, and non-HDL-C. Furthermore, hypercholesterolemia, hypertriglyceridemia, and elevated non-HDL-C were the independent risks in hypovitaminosis D population. Vitamin D deficiency in poor glycemic control is likely to develop dyslipidemia as compared to vitamin D insufficient and sufficient groups. Thus, vitamin D supplementation and an increase in exposure to sunlight may reduce the risk of cardiovascular complications in diabetes.
Every day we hear more and more about free radicals and how they are linked with innumerable diseases and health conditions from ageing to muscular degeneration and even some forms of cancer. The problem is not in knowing that these microscopic enemies exist. We know that they do! The problem is how to fight them so that they are rendered harmless. Under normal metabolic conditions each cell of human body is exposed to about 10 10 molecules of superoxide anions (primary free radical) each day. For a person weighing 150 pounds, this amounts to about 4 pounds of superoxide per year, a substantial amount! Once formed, superoxide can react through catalytic pathways in the cell to form many other reactive oxygen/nitrogen species (ROS/RNS). The antioxidant defense system in the human body is extensive and consists of multiple layers, which protect against different types of ROS/RNS. Many of the biological effects of antioxidants appear to be related to their ability not only to scavenge the deleterious free radicals but also to modulate cell signalling pathways.
Background. Subclinical hypothyroidism (SCH) is a common endocrine disorder prevalent in the Nepalese female population. Dyslipidemia, a prerequisite to the development of cardiovascular disease, links the thyroid profile and cardiovascular disease risk. This study is aimed at assessing the cardiovascular disease risk in females with SCH. Methods. This laboratory-based cross-sectional study was carried out at Manmohan Memorial Teaching Hospital, Kathmandu, Nepal, where 100 females with SCH and 100 euthyroid controls were included. Estimates of thyroid and lipid profiles were made, and lipid variables were used to calculate lipid indices. Results. In comparison to controls, females with SCH had significantly higher lipid profiles, thyroid profiles, and lipid indices but significantly lower HDL-C. The TSH ( p < 0.001 ), TG ( p = 0.039 ), VLDL ( p = 0.039 ), and AIP ( p = 0.031 ) were significantly associated with mild and severe SCH. AIP was significantly correlated with TSH ( r = 0.256 , p = 0.010 ) among SCH females. Conclusion. Our findings suggest that women with SCH are more likely to get CVD. Hence, timely monitoring of cardiovascular status among females with SCH is crucial, and it can be performed using simple lipid indices like AIP, AI, and LCI.
