Abstract
Failure of response to therapy in childhood tuberculosis may be due to resistance, paradoxical response or immunodeficiency. Interferon-γ (IFNγ) plays a major role during host defense against Mycobacterium tuberculosis (Mtb). An 8-y-old boy presented with fever, hepatosplenomegaly and parotid abscess. He had been earlier treated for BCG adenitis in infancy and at 5 y for TB osteomyelitis of iliac bone and recovered. Investigations confirmed disseminated Mycobacterium Avium Intracellulare infection. He was investigated for immunodeficiency because of recurrent mycobacterial disease and a partial defect of γ-interferon receptor was identified. He required a 2 y course of therapy with a 7 drug regimen and recovered. The authors report this case because of its rarity and to highlight the need to consider γ-interferon receptor defect in the presence of recurrent tuberculosis (TB) and also review the options for therapy.
