Background:
The purpose was to study the epidemiology of Helicobacter-negative gastritis among a large group of patients with inflammatory bowel disease (IBD) and healthy controls.
Methods:
From a computerized database of surgical pathology reports we selected 5493 patients who underwent colonoscopy and upper gastrointestinal endoscopy with biopsy results from both procedures. The presence of gastritis and duodenitis was compared among 550 case subjects with IBD and 4943 healthy control subjects. The results are expressed as prevalence rates, as well as age- and sex-adjusted odds ratios with 95% confidence intervals.
Results:
Any type gastritis was found in 13% of controls and 25% of IBD patients (Crohn's disease [CD] 33%, ulcerative colitis [UC] 19%). Duodenitis was found in 1% of controls and 13% of IBD patients (CD 26%, UC 3%). In subjects younger than 18 years the prevalence of gastritis and duodenitis were 53% and 40% in CD, respectively, and 38% and 0% in UC, respectively. Similar prevalence rates were found in men and women. The odds ratio for Helicobacter-negative chronic active gastritis associated with CD was 11.7 (7.5-18.0) and with UC 2.8 (1.4-5.0). The corresponding values for focally enhanced gastritis were 40.1 (15.5-114.9) in CD and 0 in UC.
Conclusions:
Helicobacter-negative gastritis and duodenitis occur significantly more often in patients with IBD than healthy controls. Such upper gastrointestinal inflammation appears to be particularly common in CD and younger patients.

Inflammatory Bowel Disease I: Introduction
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
