The Assessment of Vitamin D Serum Level in Patients With Pulmonary and Extra-Pulmonary Tuberculosis in Karaj, Iran, During 2017-2018.

Background: It is important to determine the type of tuberculosis and its related factors in order for effectively treating a disease and reducing its side effects in the society. Objective: This study aimed to determine vitamin D level in patients with pulmonary and extra-pulmonary tuberculosis in Karaj, Iran in 2017-2018. Materials and Methods: In this observational study, 102 patients suffering from pulmonary and extra-pulmonary tuberculosis disease were availably selected in Karaj, Iran in 2017-2018. They were examined and, then, their vitamin D level were assessed and compared according to the type of tuberculosis. Results: The study results showed that vitamin D level was normal in 39.2% of the case study population, but it was abnormal in 60.8% of it (18.6% deficiency and 42.2% insufficiency). Vitamin D deficiency was 15.8% in pulmonary tuberculosis patients and it was 22.2% in extra-pulmonary tuberculosis ones, showing no significant difference (P>0.05) statistically. Conclusion: According to the obtained results, hypovitaminosis-D was detected in more than half of the patients with pulmonary and extra pulmonary tuberculosis, which was not associated with the type of tuberculosis. Seemingly, the patients needed the same amount of – or even more – food, medical supplements, sports, and sunlight compared to healthy people
