Comparison of serum level of 25(OH) vitamin D3 in brucellosis patients with healthy persons in Hamadan, west of Iran

Abstract

Introduction: The human immune system including phagocytosis, has anessential role in pathogenesis, relapse and improvement of infectious diseases. The immune cells have vitamin D receptor, and vitamin D deficiency causes impaired immune system, specifically macrophages. The aim of study was to compare serum levelof 25-hydroxyvitamin D3 (25-OH-VitD3) among the patients with acute brucellosis and relapsed brucellosis with healthy individuals. Methodology: In this case-control study, 92 patients with acute brucellosis, 92 cases with relapsed brucellosis and 107 healthy persons who referred to Sina hospital and Imam Khomeini clinic were enrolled, and all groups were matched based on age, gender and habitat. The study was done from March 2016 to June 2017. The serum levels of 25-OH-VitD3 were measured based on the Enzyme Linked Fluorescent Assay (ELFA) technology, Vidassystem (France, Biomerieux Kit). The data were analyzed by using SPSS version 16 software. Results: The mean serum levels of 25-OH-VitD3 in acute brucellosis, relapsed brucellosis and healthy persons were 22.55 ± 15.72, 26.82 ± 20.78, 24.44 ± 17.29, respectively.In addition, the mean serum levels of 25-OH-VitD3 by male gender in acute brucellosis, relapsed brucellosis and healthy control groups were 20.35 ± 13.10, 24.88 ± 20.89 and 22.52 ± 13.79, respectively. However, there was no statistically significant difference among three groups (P = 0.275). Conclusions: According to the results, the prevalence of vitamin D deficiency was high in patients with acute or relapsed brucellosis and also healthy persons; however, there was no meaningful difference among three groups and between the patients and healthy persons.
