Is It a Coincidence or Secondary Immune Thrombocytopenic Purpura? A Case of an 11-Year-Old Male Patient at Hawassa University Comprehensive Specialized Hospital, Hawassa, Sidama, Ethiopia

BACKGROUND: Isolated thrombocytopenia with normal levels of other cell lines in the absence of other reasons is referred to as “immune thrombocytopenic purpura” (ITP). Tuberculosis has been associated with a variety of hematologic abnormalities, although severe thrombocytopenia and tuberculosis presenting as immune thrombocytopenic purpura are extremely uncommon. CASE PRESENTATION: We discuss a case of an 11-year-old male adolescent who came with epistaxis and petechial rash lasting one day, as well as severe thrombocytopenia. Following the clinical diagnosis of ITP, the patient was started on prednisone, transfused with platelets, and later started on antituberculosis (ATT) after confirmation of tuberculosis. The patient had a satisfactory response during the course of treatment, and the platelet level was fully recovered after 6 months. CONCLUSION: Tuberculosis (TB) should be recognized as a cause of immunological thrombocytopenia in tuberculosis-endemic areas. Our patient’s platelet count improved after 1 week of ATT and 2 weeks of prednisolone, and it was entirely restored after 6 months of ATT treatment. Unfortunately, there are no clear guidelines for treating TB-related immune thrombocytopenia or determining the cause of TB-related immune thrombocytopenia. Tuberculosis-induced ITP resolves with the ATT, even though more investigation is warranted.
