Background/Aims. To investigate the role of Helicobacter pylori infection in the development of enteritis (small intestinal mucosal injury). Methodology. Between April 2007 and January 2013, 99 patients undergoing capsule endoscopy (CE) were tested for anti-H. pylori immunoglobulin G antibody (Hp-IgG) using an enzyme-linked immunosorbent assay (ELISA). None of the patients had been treated for H. pylori infection or diagnosed as having Crohn’s disease or any other clinically apparent small intestinal disorders prior to the CE. Results. The overall Hp-IgG-positive rate was 26.3%. The incidence of enteritis, as diagnosed by CE, tended to be lower in the Hp-IgG-positive patients (23.1%) than in the Hp-IgG-negative patients (38.4%) (). When patients receiving aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs), well-known causes of enteritis, were excluded, the incidence of enteritis in the Hp-IgG-positive patients (11.7%) was significantly lower than that in the Hp-IgG-negative patients (43.7%) (). A binomial logistic regression analysis revealed a significant negative relationship between Hp-IgG positivity and the presence of enteritis in patients receiving neither aspirin nor NSAIDs (). Conclusions. Our data indicated that H. pylori positivity was inversely associated with the prevalence of enteritis.

Thirty infants with intractable diarrhea of infancy (IDI) underwent small bowel biopsies in order to determine the extent and duration of small intestinal mucosal injury. The onset of the persistent diarrhea occurred prior to 3 months of age and continued for an average of 48 days prior to investigation. In 18 cases, no associated entities were found. Mucosal injury was invariably found in all 30 infants: grade IV injury in 11, grade III in eight, grade II in nine, and grade I atrophy in one. Disaccharidase activities were diminished and corresponded to the degree of atrophy. Lactase activity was diminished to a greater extent than sucrase and maltase. Significant, persistent mucosal injury existed for an average of six months in 16 of the 23 (70%) repeat biopsies. All infants were given an elemental diet (ED). Twelve of the 30 infants required parenteral nutrition (PN). These infants were gradually advanced to an oral elemental diet and maintained on this diet until histologic findings and disaccharidase levels were normal. Eighteen infants were fed and maintained on an elemental diet by mouth from time of admission until normal histologic findings and disaccharidases were found. No mortality occurred during management and follow-up. Twenty-two of the 28 infants in whom follow-up growth data were available excelled in weight and height velocity. The data suggest that prolonged injury to the small intestinal mucosa is a common finding in many cases of intractable diarrhea of infancy. Elemental diets should be started early in the course of protracted diarrhea in young infants, and may need to be continued for several months since histologic and enzymatic changes of the small intestine may persist for extended periods.

Celiac disease is a disorder characterized by a permanent sensitivity to gluten, such that its presence in the diet induces an enteropathy. Exposure of susceptible individuals to gluten-containing foods causes small intestinal mucosal injury associated with malabsorption of variable severity. The association between the occurrence of malabsorption and the presence of wheat or rye in the diet was first recognized by Dicke in 1950. Subsequently, barley was also shown to be toxic. The role of oats in producing disease remains controversial, but rice and maize are known not to cause disease. EPIDEMIOLOGY Celiac disease is one of the most frequent causes of malabsorption during childhood, with prevalence rates of between 1:500 and 1:3000 commonly quoted in the literature. Although the exact prevalence in any particular region is difficult to determine, marked geographical variations do appear to exist. A preyalence rate of 1:300 has been reported in western Ireland. Similarly, celiac disease is reported more frequently in patients from European countries than from North America. There is some evidence that the incidence may also be changing. Based on studies from the United Kingdom, it has been suggested that the incidence of childhood celiac disease may have been declining in recent years, following a peak in the early 1970s.
