Abstract
Dyspepsia is poorly characterized in the pediatric population. The goal of the current study was to describe the clinical constellation and natural history of dyspepsia in children and adolescents seen in a pediatric gastroenterology practice. A standardized questionnaire was administered by a pediatric gastroenterologist to all subjects 5 or more years of age (and their parents or guardians) treated in a referral pediatric gastroenterology practice for 1 month or more of abdominal pain or discomfort, nausea, or vomiting. Subjects with dyspepsia and dyspepsia subtypes (ulcer-like, dysmotility-like) were identified by using previously defined adult criteria. Evaluation and treatment were performed at the discretion of the attending pediatric gastroenterologist. During a 1-year period, 257 patients were screened with 127 subjects fulfilling criteria for dyspepsia (59% girls, 85% white; median age, 11.7 years; median duration of symptoms, 8 months). Symptoms were ulcer-like in 26% and dysmotility-like (nausea predominance) in 15% of subjects. In those with dyspepsia, irritable bowel syndrome and gastroesophageal reflux were noted in 24% and 43%, respectively. Esophagogastroduodenoscopy and biopsy were performed in 56 subjects with 21 (38%) having mucosal inflammation (Helicobacter pylori in 5). The remaining 35 subjects (62%) were considered to have functional dyspepsia. Duration of symptoms less than 1 year and vomiting were risk factors for mucosal inflammation. Follow-up at 6 months to 2 years revealed 70% of subjects were either asymptomatic or much improved regardless of the cause of dyspepsia. Most children and adolescents with dyspepsia do not have serious disease. In our referral population H. pylori infection was unusual, and no peptic ulceration was found. Most subjects with functional dyspepsia have improvement of symptoms over time.
