Abstract
Typical as well as atypical presentations of systemic lupus erythematosus are being increasingly recognized due to improved diagnostic methods. In a tuberculosis-endemic country like India, it was traditionally believed that the occurrence of tuberculosis in lupus was due to the chronic immunosuppression caused by lupus or because of the use of steroids or isoniazid-induced lupus. Increasingly several patients with no recorded predisposition to lupus with a history of treatment for tuberculosis are coming with evidence of systemic lupus erythematosus rather than a drug-limited story. Whether the development of an autoimmune state is a mere conjecture or the presence of acid-fast bacilli in the body for a prolonged duration causes complex antigenic interactions leading to an antigenic response needs to be looked into. We present a report of three such patients and review the pathogenetic interactions that could possibly explain the role of mycobacterial antigens as a putative antigen in the pathogenesis of lupus.
