title: Helicobacter pylori, hypergastrinaemia, and recurrent abdominal pain in children.
abstract: The association between Helicobacter pylori and recurrent abdominal pain (RAP) is controversial. In this cross-sectional study, the authors aim to determine whether hypergastrinaemia causes RAP in children with H pylori gastritis. In 439 children age 4 to 13 years (mean 7.3 years) attending for nongastrointestinal day-case surgery, anti-Helicobacter immunoglobulin G (IgG) was identified in serum by an enzyme-linked immunosorbent assay (ELISA) method validated in children and fasting plasma gastrin was measured. A history of RAP was sought. One hundred twenty-seven children (29%) tested seropositive for H pylori. Fifty-one seronegative children (16.3%) and 22 seropositive children (17.3%) gave a history of RAP. The mean fasting gastrin in seronegative children was 52 ng/L compared with 117 ng/L in seropositive children (P < .001). The mean fasting gastrin in seropositive children with RAP (124 ng/L) was not significantly different from that of seropositive children without RAP (115 ng/L). The high prevalence of H pylori seropositivity in this study is at variance with other reported paediatric data from the developed world. No association between childhood H pylori gastritis, hypergastrinaemia, and RAP was found. In children with H pylori gastritis, the increase in circulating gastrin (mean 140% increase) is greater than that seen in adults (50% increase).
