Treatment of cyclic vomiting in childhood with erythromycin.
Cyclic vomiting syndrome (CVS) is an unusual cause of episodic emesis in children. It manifests as intermittent episodes of severe vomiting, similar in time of onset and duration, with no symptoms during the intervening period. Dehydration necessitating intravenous fluid therapy may occur. Most therapeutic maneuvers have proven unsuccessful. We report the use of erythromycin as a prokinetic agent in the treatment of cyclic vomiting in 24 children (10 boys, 14 girls). Many patients had mild associated abdominal pain with their vomiting. Fourteen patients had previously been given metoclopramide but none responded. Two patients were mildly developmentally delayed. Twenty-four patients were given oral erythromycin ethylsuccinate, approximately 20 mg/kg/day, in two to four divided doses for 7 days. This dose was repeated as needed when symptoms reappeared. Eighteen of 24 patients reported total resolution of symptoms when re-evaluated at 2 and 6 months. All males responded, eight of 18 responders were female, and all six with partial or no response to therapy were female. This uncontrolled trial suggests that erythromycin may be a useful prokinetic agent in the treatment of CVS in childhood. Because the study was uncontrolled, placebo effect cannot be excluded. Case-controlled, double-blinded prospective trials should be considered to evaluate the effectiveness of erythromycin in CVS.
