The efficacy of niacin supplementation in type 2 diabetes patients Study protocol of a randomized controlled trial

Background: Dyslipidemia is a main risk factor of cardiovascular disease in the diabetic patients. Niacin was found acutely to decrease the plasma concentration of free fatty acids by inhibiting their mobilization from adipose tissue. This present study is a double blinded, randomized, and prospective trial to determine the effect of niacin during dyslipidemia in type 2 diabetic patients. Methods: This randomized controlled, double-blinded, single center trial is carried out according to the principles of Declaration of Helsinki. This present study was approved in institutional review committee of the Second Affiliated Hospital of Dalian Medical University. All the patients received the informed consent. Diabetic patients were randomized (1:1) to receive 3-month treatment with extended-release niacin or matching placebo. The major outcome of our present study was the change in the level of HbA1c from the baseline to week 12. Secondary outcome measures contained the levels of fasting blood glucose, the concentrations of serum transaminase, the other laboratory variables, and self-reported adverse events. The P Results: We assumed that adding the niacin to the medication in patients with type 2 diabetes would reduce dyslipidemia and achieve target lipid levels.
