Abstract:
We report a 20-year-old young man with Henoch-Schönlein purpura (HSP) who presented with abdominal pain, arthralgia, and skin rash. The gastrointestinal tract was viewed by upper endoscopy and colonoscopy. We found characteristic endoscopic findings in the stomach, cecum and sigmoid colon, the combination of which has rarely been demonstrated in one patient. Histologic examination of skin biopsy specimens and gastrointestinal tract revealed leukocytoclastic vasculitis with positive staining for IgA in the capillaries. The clinical course of this patient was further improved after the combined therapy with steroids and immunosuppressive drug.

Peptic Ulcer Disease II: Pathophysiology
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
