ABSTRACT
Over the past few decades, there has been extensive research on the use of vitamin D as an adjunctive therapy in the treatment and prevention of tuberculosis. In vitro studies have provided valuable insights into the mechanisms by which vitamin D activates the immune response to combat Mycobacterium tuberculosis. These encouraging findings have spurred clinical investigations globally to assess the effectiveness of vitamin D as a preventive measure and as an adjunctive treatment for tuberculosis. However, the results from these clinical studies have been contradictory, with some demonstrating clear efficacy while others report only modest or no activity. In this review, we aim to analyze the clinical studies on vitamin D and examine the possible discrepancies observed in their outcomes.
