Abstract
Recurrent abdominal pain is a common problem in childhood
worldwide It was defmed by Apley in 1958 as a three episodes of
pain in a three month period and is severe enough to affect child
activities. H pylori is a gram negative bacterium involved in the
pathogenesis of variety of gastro intestinal diseases including peptic
ulcer and gastric cancer. H pylori infection is acquired mainly in
childhood, especially in developing countries. where the influence
of socioeconomic factors on the prevalence of H pylori has been
shown .association between RAP and H pylori is controversial.
Infection with H pylori has been shown to cause chronic gastritis in
essentially all infected. Some infected children also develop peptic
ulcer disease. Inflammatory changes occur in symptomatic as well as
asymptomatic children. Childhood is the critical time for acquisition
of H pylori infection . consequently attempts have been made to
verify or reject the hypothesis of a causal association between
infection and childhood gastrointestinal symptoms , including
recurrent abdominal pain . RAP is said to have an organic cause in
only 5% of investigated cases. The present study was intended to
assess the prevalence of H pylori infection in children with recurrent
abdominal pain attending the out patient pediatric clinic of Zagazig
university hospital.
