Background: Type 2 diabetes is a metabolic disorder that is associated with several complications. Recently it was suggested that vitamin D deficiency may play a vital role in the development and progression of diabetes and may impact the outcome of the disease and its associated co-morbidities as sepsis and cardiovascular disease. This study aimed to evaluate the anti-inflammatory role of vitamin D in patients with type 2 diabetes mellitus having infection and determine the effects of vitamin D supplementation on serum 25-(OH) vit. D, the metabolic profile, and inflammatory markers. Subjects and Methods: A sample of 170 patients having type 2 diabetes with infection were involved in the study. They were divided into control group receiving appropriate antibiotic therapy and intervention group receiving vitamin D supplementation (10,000 IU daily for three months) beside the antibiotic therapy. Serum 25-(OH) vitamin D, glycemic profile, random blood glucose level (RBG) and glycated hemoglobin (HbA1c) and inflammatory markers, (C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and tumor necrosis factor-alpha (TNF-α) were done at the start of the study and after three months. The outcome in the two groups was assessed at the end of the study. Results: Vitamin D is negatively correlated with RBG, HbA1c, body mass index, CRP, ESR, TNF-α. The intervention group had a better outcome at the end of the three months than the control group in terms of higher serum 25-(OH) vitamin D, good glycemic control, decreased serum levels of ESR, CRP, and TNF-α. Conclusion: Vitamin D has a strong anti-inflammatory effect and positively impacts the glycemic profile and clinical condition of patients with type 2 diabetes having infection.
