Background. Systemic lupus erythematosus (SLE) is associated with a global reduction in regulatory T cells (Tregs). Vitamin D supplementation that is efficacious, safe, and reasonably priced has the potential to reduce morbidity in SLE. This study was aimed to systematically assess the efficacy of vitamin D supplementation in enhancing Tregs concentration or Tregs-related marker. Methods. A systematic review of the literature for clinical studies was performed on Pubmed, Proquest, and Google Scholar. Studies were assessed for risk of bias using Newcastle Ottawa Scale. All clinical studies that investigated the effects of vitamin D supplementation on Tregs in SLE patients were included. Key evidence was analyzed and qualitatively synthesized. Results. Three relevant studies were included. All studies were of high-quality. Vitamin D supplementation consistently increased Tregs concentration across all included studies. Conclusion. The current study supports the evidence that vitamin D supplementation enhanced Tregs concentration in SLE patients.
