Diabetes mellitus-a true immunosuppression

Abstract

Uncontrolled diabetes mellitus predisposes to variety of infections which are very difficult to manage. Here we report a case of diabetes mellitus with pulmonary tuberculosis who did not respond to anti tubercular therapy (ATT). On further evaluation patient found to have nocardiosis co-infection which usually occurs in immunocompromised patients like malignancy/ in HIV virus infected patients. This patient did not have any such condition other than uncontrolled diabetes mellitus which predisposed to nocardiosis co-infection. This co-infection of pulmonary tuberculosis and nocardiosis is very uncommon in HIV negative individuals and is reported because of this rare presentation.
