Previous research has suggested that vitamin D has antioxidant properties. This study aimed to evaluate the effect of vitamin D on total Antioxidant Capacity (TAC) and its relationship with ICU patients’ outcomes. Methods: In this prospective randomized clinical trial, 36 ventilated ICU patients were randomly allocated to receive either a single intramuscular vitamin D 300,000 IU or its placebo. Serum Vitamin D and TAC were measured before and on day 7 after the intervention. Clinical Pulmonary Infection Score (CPIS) and sequential organ failure assessment (SOFA) scores were measured daily for seven days and on days 14 and 28. Results: Thirty patients completed the study. The results show that injection of vitamin D leads to a significant increase in the mean changes of vitamin D level on the seventh day of the study (+3.5±1.3 vs -0.4±0.2 P=0.00) and TAC levels (3.2±3.9 vs -2.0±2.6 P=0.00. ICU length of stay was 18.3±8.4 and 25.4±6.6 days in the intervention and placebo arms of the study. Twelve patients in the placebo group and 5 in the vitamin D group died within the 28 day study period. The duration of mechanical ventilation was 15.7± 9.3 vs. 22.6± 9.1 days in vitamin D and placebo arms, respectively. Conclusion: : Administration of vitamin D may increase TAC levels and decrease the length of stay and duration of mechanical ventilation in ICU patients.
