GASTROESOPHAGEAL REFLUX - A SIGNIFICANT ASSOCIATION WITH CENTRAL-NERVOUS-SYSTEM DISEASE IN CHILDREN

An association between gastroesophageal reflux (GER) and central nervous system (CNS) disease has been suggested, but not defined clearly in children. We report on 613 children (ages 1 week to 16 years; mean, 16 months) studied at three institutions who were referred to the pediatric surgical service for documentation of GER by an abnormal pH score derived from 18- to 24-hour esophageal pH monitoring. Follow-up (range, 1 to 115 months; mean, 25 months) was obtained in 368 patients. One hundred thirty-two children had CNS disease documented prior to the evaluation for GER. In children older than 1 year, there was an increased incidence of GER ( 31 45, 69%) in those children with CNS disease compared with those without CNS disease ( 38 81, 47%; P = .014). On follow-up, only 4.6% ( 14 282) of children who were not diagnosed initially with CNS disease were found later to have overt CNS disease. There was no significant difference in the prevalance of newly diagnosed CNS disease in children with and without GER in long-term follow-up. In conclusion, in the population of children referred to the pediatric surgeon for evaluation of GER, children older than 1 year with CNS disease are at high risk to have associated GER documented by extended esophageal pH monitoring. Despite this association, those children with GER and no obvious CNS disease do not appear to be at increased risk to develop CNS disease. © 1991.
