Effects of Helicobacter pylori treatment on the incidences of autoimmune diseases and inflammatory bowel disease in patients with diabetes mellitus.

Abstract

BackgroundHelicobacter pylori infection is known to decrease the incidences of autoimmune diseases and inflammatory bowel disease(IBD). Our aim was investigating the effect of H. pylori treatment in diabetes mellitus(DM) patients.MethodsAdults with newly-diagnosed H. pylori infection or peptic ulcer disease(PUD) within the general population and DM population were identified from the National Health Insurance Research Database of Taiwan from 2000-2010. 79,181 patients were assigned to the 3 groups: general population with PUD without H. pylori treatment(PUD-HPRx in general population), DM patients with PUD without H. pylori treatment(PUD-HPRx in DM), and DM patients with PUD who received H. pylori treatment(PUD+HPRx in DM).ResultsHigher incidences of autoimmune diseases and IBD were observed in the PUD+HPRx in DM group than in the PUD-HPRx in general population and PUD-HPRx in DM groups (autoimmune diseases = 5.14% vs 3.47% and 3.65%; IBD = 5.60% vs 3.17% and 3.25%; PConclusionsThe results revealed that H. pylori treatment increased the incidences of autoimmune diseases and IBD and decreased the all-cause mortality in the DM group with PUD. The effect was more significant in younger patients. This finding assists in realizing the influence of H. pylori treatment in the DM population.
