- Abstract
Objective: Data regarding Helicobacter pylori (H. pylori)-associated mucosa-associated lymphoid tissue (MALT) lymphoma in children are lacking. We aimed to characterize the diagnosis, management, and outcome of H. pylori-associated MALT lymphoma in pediatric patients., Study Design: A retrospective multicenter case series of the pediatric patients with H. pylori-associated MALT lymphoma who were diagnosed during 2010-2022., Results: Five children, of them three females, were identified. The mean age at diagnosis was 14.6 ± 2.4 years. The clinical presentation included abdominal pain (5/5), nausea (3/5), weight loss, night sweats, recurrent fever (1/5), and iron deficiency anemia (2/5). Endoscopic findings in both the stomach antrum and body included a fragile and hyperemic mucosa, large ulcers, extensive nodularity, and exudate. All the biopsies from the gastric mucosa were consistent with MALT lymphoma, and positive for H. pylori (by Giemsa stain). All the patients received triple therapy (amoxicillin, nitroimidazole, or a macrolide, and a proton pump inhibitor, for 14 days), and achieved H. pylori eradication. All had complete resolution of histological findings at the last follow-up. In one patient, the histology of MALT lymphoma persisted 12 months after H. pylori eradication, and only the 18-month-biopsy was free of residual disease., Conclusions: In this series of pediatric MALT lymphoma, complete resolution of disease occurred in all the patients, yet histological remission was delayed in one. This supports the importance of endoscopic follow-up., (© 2024 John Wiley & Sons Ltd.)
