title: Prevalence of Helicobacter pylori in neonates and young infants undergoing ERCP for diagnosis of neonatal cholestasis.
abstract: This study was carried out to determine the prevalence of Helicobacter pylori infection in 20 neonates and young infants from lower socioeconomic background undergoing endoscopic retrograde cholangiopancreatography (ERCP) examination for diagnosis of neonatal cholestasis. One young asymptomatic infant (5%) who was breast-feeding with complementary formula had H. pylori infection. Endoscopy showed a normal appearing mucosa and histology demonstrated mild superficial acute gastritis. A follow-up gastroscopy performed 14 months after the initial study showed normal histology without evidence of H. pylori, suggesting that the infection was transient. Nineteen (95%) of the 20 mothers had H. pylori infection, including the mother with the infant positive for H. pylori. All mothers had gastritis on biopsy specimens. Despite the high prevalence of H. pylori in the mothers, infection in neonates and young infants was uncommon.
