Efficacy of Seluang Fish Oil (Rasbora Argyrotaenia) and Synbiotics Supplementation on CD4+CD25+ Foxp3+ T-regulator Cells, IL17/IL-10 Ratio, and Disease Activity in Systemic Lupus Erythematosus Patients

The study aimed to evaluate the efficacy of seluang fish oil (Rasbora argyrotaenia) and synbiotics (containing Lactobacillus helveticus R0052 60%, Bifidobacterium infantis R0033 20%, Bifidobacterium bifidum R0071 20% and frukto-oligosaccharide 80 mg) supplementation compared to placebo towards Systemic Lupus Erythematosus disease activity Index (SLEDAI)-2K score, IL-17/IL-10 ratio and CD4+ CD25+ Foxp3+T-regulator levels 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 18-55 years old SLE patients diagnosed based on SLICC criteria, with mild to moderate disease activity, were clinically stable for ≥ 4 months (on prednison ≤ 20 mg/day or equivalent) and willingly ceased vitamin D and probiotic consumption during the trial study. Participants were randomized into two groups receiving seluang fish oil and synbiotics supplementation, or placebo. Evaluations were conducted on week 4, 8 and 12 for clinical symptoms, side effects and adherence. IL-17/IL-10 ratio and CD4+ CD25+ Foxp3+T-regulator levels were evaluated at the beginning and at the end of the 12 week trial for analysis.
