[Bronchial asthma and duodenal ulcer and erosive bulbo-duodenitis in children: report of 6 cases].

The coexistence of moderate and severe asthma and duodenal ulcer is not very well established as yet. We started a protocol trying to establish the presence of reflux esophagitis in children with moderate or severe asthma. Thirty two patients underwent upper digestive endoscopy and, surprisingly, we found six children (18.7%) with the following digestive aspects: four children had duodenal ulcer, and two had erosive duodenitis. We report these cases and discuss some etiopathogenic aspects about these possible association, and beware the clinician to pay attention to abdominal pain in children with bronchial asthma.
