Effects of sesame seed supplementation on lipid profile and oxidative stress biomarkers in patients with knee osteoarthritis.

BACKGROUND This study was designed to assess the effect of sesame seed on lipid profile and oxidative stress biomarkers in knee osteoarthritis (OA) patients. METHODS Fifty patients with knee OA were allocated into two groups receiving 40 g of sesame seed daily along with standard medical therapy (n=25) or stan-dard treatment (n=25) for two months. Serum total antioxidant capacity, ma-londialdehyde (MDA) and lipid profile (total cholesterol (TC), HDL-cholesterol, LDL-cholesterol, triglycerides) were measured. RESULTS After the intervention period two months of study, serum TC, LDL-cholesterol and MDA decreased significantly in the sesame group (P<0.05), while no significant difference in serum values of lipid profile and oxidative stress parameters was seen in the control group (P>0.05). There was no signifi-cant difference in pre and post-treatment values of lipid profile and oxidative parameters between the two groups (P>0.05). CONCLUSION Current study showed a positive effect of sesame seed in improv-ing lipid profile and oxidative stress in patients with knee OA and indicated the fact that sesame seed might be of help to reduce oxidative stress in OA patients.
