Acute Immune Thrombocytopenia Secondary to Helicobacter Pylori Infection in a Child: A Case Report

Helicobacter pylori (H. pylori) infection is increasingly recognized as a trigger for secondary immune thrombocytopenia (ITP). We report the case of a 4-year-old boy with acute ITP refractory to first-line immunosuppressive therapy who showed significant clinical improvement following the detection and eradication of an H. pylori infection. This case underscores the importance of considering H. pylori as an underlying etiology in pediatric patients presenting with ITP, particularly those with gastrointestinal symptoms or a suboptimal response to standard treatment.
