Globally, tuberculosis is one of the major causes of morbidity and mortality in many countries. Previous studies suggest that the incidence and severity of tuberculosis are associated with low levels of vitamin D (Vit D). Therefore, this study aimed to determine the occurrence and associated factors of vitamin D3 deficiency in pulmonary tuberculosis patients at White Nile State, Sudan. 101 individuals of diagnosed pulmonary tuberculosis patients (71 males and 30 females) and 100 non-TB controls (58 males and 42 females) were included in this study. Sputum samples were obtained from TB patients and subjected to examination for acid-fast bacilli (AFB) using Ziehl-Neelsen (ZN) stain and Gene Xpert analysis. Blood samples were collected from both groups and Serum 25(OH)-vitamin D3 was determined by an Enzyme-Linked Immunosorbent Assay. HIV infection in Tuberculosis (TB) group was also investigated using the immunochromatographic test. In our study, the majority of TB patients were suffered from TB relapse (36.6%); non-HIV infected individuals (99.1%) or showed a positive result for AFB (61.4%) in Gene Xpert analysis. Moreover, there is a significant difference in microscopy findings and bacillary levels of AFB, and Rifampicin (RIF) susceptibility pattern ofstrain among sputum samples of TB patients, P-values less 0.0001. Furthermore, we found that TB patients were suffered from vitamin D deficiency. In particular, the mean of vitamin D level was significantly much lower in TB patients (26.7± 1.6) compared to non-TB controls (117.3 ± 3.2), P-value equal 0.0001. Likewise, it's much lower in females, individuals of 21-40 years old, and patients with high bacillary levels or those infected by Rifampicin resistance strain. Accordingly, our study was highlighted the TB and Vit D deficiency relationship and showed the need for further studies to a better understanding of the impact of TB on Vit D level and investigate whether vitamin D supplementation can have a role in the prevention and treatment of tuberculosis.
