Abstract

Purpose

Interleukin-1β (IL-1β) polymorphisms are associated with peptic ulcer and atrophic gastritis. This study aimed to examine effects of corpus atrophy and the genotypes of genes related to peptic ulcer, including IL-1β, on risk of aspirin ulcer.

Methods

232 patients taking 100 mg of aspirin for cardiovascular diseases, of whom 40 had peptic ulcer, were enrolled. IL1β, interleukin-1 receptor antagonist (IL-1RN), tumor necrosis factor (TNF), cyclooxygenase (COX)-1, cytochrome p450 2C9 (CYP2C9), UDP-glucuronosyltransferase (UGT1A6) genotypes were determined, and serum pepsinogen levels were measured.

Results

The polymorphisms of IL-1β-511/-31 were significantly associated with peptic ulcer, but other genotypes were not. Serum pepsinogen I and II levels and I/II ratio were significantly higher in the ulcer group than in the non-ulcer group. Taking PPI [adjusted odds ratio (OR), 0.09; 95% confidence interval (CI), 0.02–0.39], pepsinogen I of less than 50 ng/ml (OR, 0.24; 95% CI, 0.10–0.56) and IL-1β-511 T carrier (OR, 0.42; 95% CI, 0.18–0.93) were significantly associated with peptic ulcer.

Conclusions

Hypoacidity related to corpus atrophy as well as taking PPI seems to be preventively associated with development of peptic ulcer among low dose aspirin users.

Reizdarmsyndrom: Diäten wirksamer als Medikamente

29.04.2024 Reizdarmsyndrom Nachrichten

Bei Reizdarmsyndrom scheinen Diäten, wie etwa die FODMAP-arme oder die kohlenhydratreduzierte Ernährung, effektiver als eine medikamentöse Therapie zu sein. Das hat eine Studie aus Schweden ergeben, die die drei Therapieoptionen im direkten Vergleich analysierte.
