Abstract

We investigated the clinical and endoscopic features of gastrointestinal lesions in adults with Henoch-Schönlein purpura (HSP) causing gastrointestinal bleeding. The study included 24 adult HSP patients with gastrointestinal hemorrhage who underwent both upper gastrointestinal endoscopy and colonoscopy. The controls were 27 adult HSP patients without gastrointestinal hemorrhage. Patients with gastrointestinal bleeding showed higher frequencies of purpura on the upper extremities and trunk, and of elevated serum C-reactive protein (CRP). The rate of concurrent lesions in both the upper and lower gastrointestinal tracts was 91.7 %. The second portion of duodenum and terminal ileum were most frequently and severely involved. Leukocytoclastic vasculitis was detected in severe lesions and was significantly associated with mucosal ischemic changes. Most lesions (95.7 %) dramatically improved after corticosteroid therapy. This study suggests that both upper and lower gastrointestinal examinations are necessary for proper evaluation of gastrointestinal bleeding in patients with HSP.
