Background.Helicobacter pylori infection is thought to modify susceptibility to gastroenteritis.Methods.Members of northern California households with an index case of gastroenteritis were interviewed regarding recent episodes and tested forH. pylori. Conditional logistic regression was used to evaluate the risk of secondary gastroenteritis within households matched for members with secondary gastroenteritis (cases) and those without symptoms (control subjects). Case and control subjects were also tested for hepatitis A virus (HAV).Results.Of 801 households, 205 (26%) had at least 1 member with secondary gastroenteritis, of which 116 (56%) also included at least 1 member without symptoms (158 case and 285 control subjects). Compared with uninfected members and adjusting for age, those with antibodies to only 1 infection were at a decreased risk of secondary gastroenteritis (odds ratio [OR] forH. pyloriinfection, 0.25 [95% confidence interval {CI}, 0.08–0.82]; OR for HAV, 0.45 [95% CI, 0.23–0.87]). Having antibodies to bothH. pyloriand HAV did not add to this negative effect (adjusted OR, 0.39 [95% CI, 0.18–0.84]).Conclusions.H. pyloridid not increase the risk of gastroenteritis in these households. A strong negative association betweenH. pyloriinfection and gastroenteritis is likely explained by prior exposure and immunity to other enteric pathogens.
