Summary

A 54-year-old woman was seen by her primary care internist for a general health maintenance visit. Her major chronic illness was immune thrombocytopenic purpura (ITP) for which she had been treated with prednisone therapy for the past 15 years. Recent review of possible aetiologies of her chronic thrombocytopenia revealed infection with Helicobacter pylori. Successful eradication resulted in complete resolution of her thrombocytopenia within 2 months. She was weaned from steroid therapy and at 1-year follow-up, her platelet counts remained in the normal range. This case report summarises what is known about the association of H. pylori infection and ITP.
