Vitamin D status in Pulmonary Tuberculosis : a case control study

Pulmonary tuberculosis is the major cause of morbidity and mortality in the developing world. In South Asia, 80% of the apparently healthy population have vitamin D deficiency ( 30ng/ml as normal. Thirty partici- pants in each group were enrolled, from whom serum vitamin D concentration was measured, analyzed and interpreted. Mean serum vitamin D level was significantly low in case group than control group (p <0.05). The odds ratio corresponding to vitamin D deficiency in case group compared to control was 5.21 [95% CI (1.12 –27.53), (p= 0.015)]. Result indicates patients having vitamin D level <20 ng/ml has 5.21 times more risk to develop pulmonary tuberculo- sis. In conclusion, Vitamin D deficiency was significantly low in pulmonary tuberculo- sis patients and supplementation is required for them.BSMMU J 2021; 14(3): 85-91
