Gastroduodenal lesions and Helicobacter pylori in children with end-stage renal disease

Thirty-seven children with end-stage renal disease were evaluated for gastroduodenal lesions by upper gastrointestinal endoscopy between January 1993 and January 1998. The mean (+/-SD) age of the patients was 14.3+/-2.4 years (range 9-17 years). Endoscopic examination was abnormal in 17 patients (46%). The lesions were antral gastritis plus bulbitis (n=6), nodular bulbitis (n=4), antral gastritis (n=4), and duodenal ulcer (n=3). Fifteen patients had symptoms related to gastroduodenal disease, whereas 22 patients were asymptomatic at the time of endoscopic examination; 80% of the symptomatic and 23% of the asymptomatic patients had gastroduodenal lesions on endoscopy. Antral mucosal biopsy was taken from 26 of 37 children for the detection of Helicobacter pylori by the urease test. H. pylori was detected in 10 of 16 patients with gastroduodenal lesions (8 symptomatic, 2 asymptomatic). None of the patients with normal endoscopic examination were positive for H, pylori. Thus, we have demonstrated a significant number of gastroduodenal lesions and their frequent association with H. pylori in our pediatric renal transplant candidates. Our results emphasize the importance of gastrointestinal evaluation in these patients. Endoscopic examination should be considered in symptomatic patients and in areas where H. pylori is endemic.
