Introduction: A The effect of vitamin D deficiency in manifestation of sepsis and its role as an important mediator in the immune system has received attention. The present study was done with the aim of evaluating the correlation between serum levels of vitamin D and outcome of sepsis patients.
Methods: A The present cross-sectional study was performed on patients over 18 years of age suspected to sepsis presenting to an emergency department during 1 year using non-probability convenience sampling. For all eligible patients, blood sample was drawn for measurement of serum level of vitamin D3 and the correlation of this vitamin with outcomes such as mortality, renal failure, liver failure and etc. was assessed.
Results:Â 168 patients with the mean age of 70.8 Â± 13.3 (43.0 â€“ 93.0) years were studied (56.0% male). Mean serum level of vitamin D3 in the studied patients was 19.03 Â± 13.08 (4.0 â€“ 85.0) ng/ml. By considering 20 â€“ 50 ng/ml as the normal range of vitamin D, 61.6% of the patients had vitamin D deficiency. Only age (r=-0.261, p=0.037) and mortality (r=-0.426, p=0.025) showed a significant correlation with mean vitamin D. Sepsis patients with older age and those who died had a lower level of vitamin D. Area under the ROC curve of serum vitamin D level regarding 1-month mortality of the sepsis patients was 0.701 (95%CI: 0.439 â€“ 0.964).
Conclusion: ABased on the results of the present study, the prevalence of vitamin D deficiency in sepsis patients presenting to the ED was estimated as 61.6%. A significant and indirect correlation was found between the serum level of vitamin D3 and mortality as well as older age. It seems that consumption of vitamin D supplements might be helpful in decreasing the prevalence of infection, sepsis, and mortality caused by it, especially in older age.
