OBJECTIVE:The prevalence of gastroesophageal reflux disease (GERD) was randomly investigated among Dutch and Belgian intellectually disabled individuals.METHODS:In six institutes including 1607 residents, 435 persons with IQ <50 underwent 24-h esophageal pH-metry and were scored for possible predisposing factors and characteristic reflux symptoms. In 49 (11.2%) cases the test failed because of technical reasons. A pathological pH test was defined as a pH <4 for > 4.5% of the measured time. Subjects with a pathological pH test (patients) were compared with those with a normal pH test (controls).RESULTS:Of the remaining individuals, 51.8% (200/386) showed a normal pH test, whereas 186 showed a pathological pH test (median duration pH <4: 14.2%, range: 4.5–78.4%). As possible predisposing factors scoliosis, cerebral palsy, use of anticonvulsant drugs or other benzodiazepines, and IQ <35 were found, whereas symptoms such as vomiting, hematemesis, rumination, and depressive symptoms were indicative for reflux. At endoscopy reflux esophagitis was diagnosed in 129 of the 186 patients (69.4%). In 61 (47.3%) of 129 patients, grade I, 43 (33.3%) grade II, 25 (19.4%) grade III/IV (Savary-Miller) were found. Barretts esophagus was found in 18 (14.0%) and peptic strictures in five (3.9%) cases.CONCLUSIONS:An abnormal 24-h pH-metry and symptoms suggestive for GERD were documented frequently in a large cohort of institutionalized intellectually disabled individuals. Further endoscopical evaluation confirmed the diagnosis of reflux esophagitis in the majority of these individuals.

Gastroesophageal reflux disease (GERD) is an important and frequently occurring problem among intellectually disabled individuals (IDI). Early suspicion and recognition of the presence of GERD in IDI is the cornerstone of adequate management of these patients. The prevalence of GERD among institutionalized IDI with an IQ < 50 is about 50%, with 70% of these reflux patients having endoscopically established reflux esophagitis. In case of symptoms as hematemesis, rumination, or dental erosions, there is an increased risk for GERD. GERD has also been shown to be associated with cerebral palsy, an IQ < 35, scoliosis, and the use of anticonvulsant drugs or benzodiazepines. To establish the diagnosis, 24-h pH measurement or endoscopy should be used in all those intellectually disabled individuals in whom GERD clinically is suspected. The efficacy of proton-pump inhibitors (PPIs) in IDI with GERD is indisputable. In IDI, adults as well as children, PPIs are highly effective, independent of the severity of esophagitis. Marked improvement of symptoms and quality of life can be noticed after medical treatment, thereby decreasing the need for surgery in this complicated group of patients.

BACKGROUND The prevalence of reflux oesophagitis (RO) in the normally intellectual population is about 2%, while this condition in the intellectually disabled has an estimated prevalence of 10%. METHODS We investigated the presence of RO among 1687 intellectually disabled, with an IQ < 50, from 5 different institutes in the Netherlands. All were scored for possible associated factors and reflux symptoms, and compared with the overall population (n = 1580) from the same institutes (controls). Also, the effect of treatment on symptoms was evaluated after at least one year of therapy. RESULTS Gastro-oesophageal reflux disease (GORD) was suspected clinically in 169 patients based on the following symptoms: vomiting, haematemesis, anaemia, rumination or behaviour problems. At endoscopy RO was diagnosed in 107 of 1687 patients (6.4%): 17 (15.9%) grade I, 34 (31.8%) gr. II, 42 (39.3%) gr. III and 14 (13.1%) gr. IV RO (Savary-Miller classification). Cerebral palsy, constipation, anticonvulsant drugs, an IQ < 35, underweight and gastrostomy feeding appeared to be possible associated factors, while as reflux symptoms persistent vomiting, haematemesis, iron deficiency anaemia, rumination, and behaviour problems were found. Concerning therapy, surgery was found to be effective in 38%, H2 receptor antagonists in 60% and the proton-pump inhibitor omeprazole in 96%. CONCLUSIONS In this group of Dutch intellectually disabled patients with IQ < 50 RO was diagnosed in about 6% (107 of 1687), mostly severe grades of oesophagitis. Several possible associated factors were significantly present. From non-specific reflux symptoms persistent vomiting was the most indicative factor. In this population the most effective treatment of RO was long-term omeprazole therapy.

The prevalence of gastro-oesophageal reflux disease (GERD) has been suggested to be high in persons with an intellectual disability (ID). However, this has never been randomly investigated. Also, the therapeutic approach to GERD in IDI has not been studied extensively. Therefore, we studied the prevalence of GERD among IDI and the effects of omeprazole on healing and symptom relief. Four hundred and thirty-five persons with an IQ < 50 underwent 24 hour oesophageal pH testing, and after endoscopy the effects of omeprazole were evaluated. Almost 50% showed a pathological pH test. In almost 90% the treatment scheme was effective in healing the oesophagitis and keeping the patients in remission, independent of the severity of the oesophagitis. A marked improvement in symptoms was seen. GERD is a major clinical problem in IDI, and is frequently overlooked and underrated. The prevalence of GERD is high. In this difficult group of patients it appeared to be relatively easy to diagnose GERD by pH testing and/or endoscopy. Also, it was demonstrated that in IDI, omeprazol is highly effective with only a few minor side-effects.
