curcumin and Polyneuropathies

Diabetic Sensorimotor Polyneuropathy (DSPN) is a common complication of diabetes mellitus. Curcumin is the most important ingredient found in turmeric which has a very high potential for eliminating free radicals and inhibiting oxidative stress as an antioxidant agent. The aim of this study was to determine the effect of Nano-curcumin supplementation on the severity of sensorimotor polyneuropathy in patients with Type 2 diabetes mellitus (T2DM).. This parallel, double-blind randomized, placebo-controlled clinical trial was conducted on 80 diabetic patients. Participants were allocated randomly to the intervention (n = 40) and the control group (n = 40). They received 80 mg of nano-curcumin or placebo capsules for 8 weeks. Anthropometric measurements, dietary intake, physical activity, glycemic indices and the severity of DSPN were measured before and after the intervention.. Supplementation of nano curcumin was accounted for a significant reduction in Glycated hemoglobin(HbA1c) (p < 0.001) and Fast Blood Sugar(FBS) (p = 0.004), total score of neuropathy (p < 0.001), total reflex score (p = 0.04) and temperature (p = 0.01) compared to placebo group.. Our findings indicated that curcumin supplementation for 2 months improved and reduced the severity of DSPN in patients with T2DM.
