BACKGROUND: The prevalence of duodenal ulcer (DU) has been considered high in patients with chronic pancreatitis; however, its pathogenesis is unclear. We hypothesized that Helicobacter pylori infection plays the major pathogenetic role.
STUDY: One hundred seven cases (97 men, 10 women) of chronic alcoholic pancreatitis (CAP) were prospectively investigated from 1997 to 2001. One hundred thirty-seven DU patients and 59 nonulcer dyspepsia patients formed the two control groups. Pancreatic function was evaluated by determination of fecal fat excretion and fasting blood glucose concentration. Upper gastrointestinal endoscopy was performed in all patients, and gastric mucosal biopsies were taken for assessment of H. pylori infection with a modified Giemsa stain and rapid urease test.
RESULTS: Fifteen (14%) of the 107 patients with CAP had active DU. There was a trend toward an association between the presence of diabetes mellitus and/or steatorrhea and the occurrence of DU in patients with CAP (p = 0.06). The rate of H. pylori infection was significantly higher in patients with CAP and DU than in those with only CAP (86.7% vs. 54.3%, p = 0.02) but the rate similar to that in patients with simple DU (75.2%). Trends toward higher prevalence of H. pylori infection in CAP with DU were noticed when they were compared with the nonulcer dyspepsia group (86.7% vs. 66.1%). There was no significant difference in prevalence of H. pylori between CAP patients without DU and dyspeptic patients (54.3% vs. 66.1%).
CONCLUSIONS: These data demonstrate that the prevalence of DU in CAP is relatively high. H. pylori infection seems to play the major pathogenetic role in DU associated with CAP.
