Objectives. To assess the relationship between @entity281 and the risk of pediatric-onset @entity29 ( @entity29 ). Methods. We conducted a nested case-control study of 501 incident cases aged  <=17 years and 9,442 controls who were members of Kaiser Permanente Northern California for at least one consecutive year between 1996 and 2006. @entity29 was confirmed and the incidence date was adjudicated by pediatric gastroenterologists. @entity580 were identified from the principal diagnosis code of electronic inpatient records. Medications to treat @entity281 were identified during the hospitalization. Conditional logistic regression was used to assess the associations between hospitalized @entity281 , medications, and @entity30 and @entity31 . Results. In the year prior to diagnosis, both hospitalized infection of any system (OR 6.3; 95% CI 1.6-23.9) and hospitalized @entity281 (OR 19.4; 95% CI 2.6-143.2) were associated with @entity1050 . @entity580 of any system were inversely associated with UC after excluding the year prior to diagnosis (OR 0.4; 95% CI 0.2-0.9). No UC case had a hospitalized @entity344 prior to diagnosis. Conclusion. Infections appear to play opposite roles prior to the diagnosis of @entity1050 and UC. Infections may be associated with an increased risk of @entity1050 and a decreased risk of UC.
