Case Report: Pulmonary tuberculosis and raised transaminases without pre-existing liver disease- Do we need to modify the antitubercular therapy?

We report a case of an adult female with pulmonary tuberculosis who had biochemical evidence of liver injury during the presentation manifested as raised transaminases, but without clinically obvious pre-existing liver disease nor a history of hepatotoxic drug use. This is a fairly common scenario seen in tuberculosis endemic areas; however, this is an under reported condition in the literature and guidelines for its management has not been established. Many clinicians including the authors have treated such cases with modified liver friendly regimens in fear of increasing the hepatotoxicity with standard antitubercular drugs. However, the modified regimens may not be optimal in treating the underlying tuberculosis. In this report, we gave full dose standard drugs, and the liver injury resolved as evidenced by normalization of transaminases. Further research is required in this regard, but the presence of transaminitis with no obvious common underlying etiology may not warrant a modification of standard antitubercular regimen.
