Mucosal eosinophilia and response to H1/H2 antagonist and cromolyn therapy in pediatric dyspepsia

Clinical Pediatrics
Craig A FriesenSusan M Abdel-Rahman

Abstract

Both eosinophils and mast cells have been implicated in the generation of abdominal pain. The purposes of this retrospective study were to determine the prevalence of duodenal eosinophilia in pediatric dyspepsia and to determine the clinical response rate of these patients to combined H1 and H2 receptor antagonist and mast cell stabilizer therapy. Fifty-nine patients (ages 3.5-17.7 years) with dyspepsia undergoing endoscopy were evaluated. All patients had a minimum of 2 forceps biopsies obtained from each of the esophagus, antrum, and duodenal bulb. Routine histologic evaluation was performed and duodenal biopsies were additionally evaluated to determine eosinophil counts. Patients with > 10 eosinophils/hpf were treated with ranitidine and hydroxyzine (H1/H2). Nonresponders were then treated with oral cromolyn. Patients were followed up and response recorded in an abdominal pain database and/or medical chart, which were reviewed for this study. Forty-two patients (71%) had duodenal eosinophilia. Twenty-one (50%) of these were responders to H1/H2. The response rate did not differ between patients with and without noneosinophilic esophagitis, gastritis, or duodenitis, respectively. Two patients were lost to follow-up and conside...Continue Reading
