Summary
Gastrointestinal symptoms and lesions are common in systemic mastocytosis, often underestimated. Further research is needed to understand the causes of diarrhea and malabsorption in these patients.
Area of Science:
- Gastroenterology
- Hematology
- Internal Medicine
Background:
- Gastrointestinal (GI) involvement in systemic mastocytosis (SM) is more frequent than previously thought.
- Up to 80% of SM patients exhibit GI symptoms, with frequent abnormalities detected via endoscopy and functional studies.
Purpose of the Study:
- To review the current understanding of GI involvement in SM.
- To highlight knowledge gaps regarding GI lesions, diarrhea, and malabsorption in SM patients.
Main Methods:
- Review of existing literature on GI manifestations in systemic mastocytosis.
- Analysis of studies on endoscopic findings, functional absorption tests, and gastric acid secretion.
Main Results:
- Gastric acid hypersecretion, potentially leading to ulcer disease and malabsorption, occurs in some SM patients.
- Prevalence of peptic ulcer disease in SM is likely underestimated.
- The pathophysiology of diarrhea and abdominal pain in SM remains largely unclear.
Conclusions:
- GI involvement is a significant and often overlooked aspect of systemic mastocytosis.
- Further prospective studies are crucial to elucidate the mechanisms behind GI symptoms and lesions in SM.
