Immune thrombocytopenic purpura secondary to Helicobacter pylori

Lintu Ramachandran et al. Proc (Bayl Univ Med Cent). .

Abstract

Immune thrombocytopenic purpura is a disorder characterized by decreased platelet count that may be secondary to infectious or autoimmune etiologies. We present a patient with upper gastrointestinal bleeding complicated by severe thrombocytopenia. Endoscopy revealed gastritis with pathology positive for Helicobacter pylori. Platelet count normalized after triple antibiotic therapy. The precise mechanism by which H. pylori causes immune thrombocytopenic purpura remains unclear; however, there are several plausible mechanisms. This case highlights the importance of keeping H. pylori in the differential in patients presenting with thrombocytopenia.

Keywords: Helicobacter pylori; immune thrombocytopenic purpura.
