Seluang Fish (Rasbora Spp.) Oil Decreases Inflammatory Cytokines Via Increasing Vitamin D Level in Systemic Lupus Erythematosus

BACKGROUND: Systemic Lupus Erythematosus (SLE) is an autoimmune disorder mediated by inflammatory cytokines. Decreasing vitamin D levels is a common feature in SLE patients. Vitamin D has the capacity in suppressing inflammatory cascade. Seluang fish (Rasbora spp.) contained a high level of vitamin D with the potential as a new therapeutic modality. AIM: This study aimed to assess the efficacy of Seluang fish oil against proinflammatory cytokines, vitamin D levels, and clinical conditions of SLE. METHODS: A randomised, double-blind, clinical trial study design was conducted. The subjects were 16 SLE subjects treated with 500uL Seluang fish oil capsules and 16 SLE subjects with placebo capsules. Measurement of vitamin D, IL-1, IL-6 and IL-17 levels were performed with ELISA. Clinical assessment of SLE was performed with MEX-SLEDAI. Bivariate analysis, T-test, was performed. Data were presented in the form of mean ± SD. RESULTS: The administration of Seluang fish oil was clinically able to show efficacy assessed by the MEX SLEDAI score. Significant results were also shown by increased vitamin D levels and reduced levels of IL-1, IL-6 and IL-17, in Seluang fish oil group. CONCLUSION: Seluang fish oil possessed the efficacy of reducing the inflammatory response in SLE patients by increasing serum vitamin D levels.
