Brief summary
The study aimed to evaluate the efficacy of vitamin C supplementation compared to placebo towards IL-6 levels and disease activity with the MEX-SLEDAI score in Systemic Lupus Erythematosus (SLE) patients. The current study was designed as a single-center double-blind randomized controlled clinical trial. The participants were voluntarily recruited ≥ 18 years old SLE patients, with mild to moderate disease activity and did not consumed vitamin C 1 week prior to the trial study. Participants were randomized into two groups receiving vitamin C supplementation, or placebo. IL-6 levels and MEX-SLEDAI score were evaluated at the beginning and at the end of the 8 week trial for analysis.
Detailed description
This research is a double blind randomized controlled trial study. The study subjects were 38 patients diagnosed with mild to moderate lupus activity, randomly divided into 2 groups, who received vitamin C supplementation twice daily for 8 weeks and the group that received placebo. Serum IL-6 and the degree of disease activity using MEX-SLEDAI score were measured before and after treatment.
