Immune thrombocytopenia complicating pulmonary tuberculosis: Case report and investigation of mechanisms

Immune thrombocytopenia and pulmonary tuberculosis presented concurrently in a 20 year old Thai man as a bleeding diathesis. Intravenous immunoglobulin rapidly corrected the thrombocytopenia. Immunofluorescence and immunoblot studies with platelets and mycobacteria showed the presence of platelet surface membrane IgG.
