title: Effect of Sesamin Supplementation on Cardiovascular Risk Factors in Women with Rheumatoid Arthritis.
abstract: Rheumatoid arthritis (RA) is an inflammatory disease with increased mortality from cardiovascular disease (CVD). Oxidative stress has a critical role in the pathogenesis of RA and CVD. Sesamin, the main lignin constituent of sesame, has several antioxidant and anti-inflammatory effects. This study aimed to investigate the effects of sesamin supplementation on anthropometric indices, lipid profile, blood pressure, and oxidative stress markers in women with RA.
  
  
  
  In this randomized, double-blind, placebo-controlled clinical trial, 44 patients with RA were randomly divided into 2 groups (intervention and control). Patients consumed 200 mg/day sesamin supplement and placebo in the intervention and control groups, respectively, for 6 weeks (spring 2014). At baseline and at the end of the study, anthropometric indices and blood pressure were assessed. Serum concentrations of lipid profile, malondialdehyde (MDA), and total antioxidant capacity (TAC) were also determined.
  
  
  
  At the end of study, sesamin supplementation significantly decreased serum levels of MDA (p = 0.018) and increased TAC and high-density lipoprotein cholesterol (HDL-C) levels in patients with RA (p = 0.020 and p = 0.007, respectively). In the sesamin group, the mean of weight, body mass index, waist-to-hip ratio, body fat, systolic blood pressure, and the concentration of other lipid profiles (triglycerides, total cholesterol, and low-density lipoprotein cholesterol [LDL-C]) were also significantly decreased at the end of study compared to baseline values (p < 0.05). However, the difference between the 2 groups was not statistically significant in this regard (p > 0.05).
  
  
  
  Sesamin exhibited a protective effect on cardiovascular risk factors in patients with RA. However, further investigation is suggested.
