Helicobacter pylori infection has been linked to gastritis, diarrhea, peptic ulcers, failure-to-thrive, and anemia. It has also been linked to predisposition to gastric malignancies.
Many internationally adopted children have diarrhea, failure-to-thrive, and anemia on arrival to the United States.
In this study, researchers from Boston, Massachusetts, determined the prevalence of H. pylori antibodies in internationally adopted children.
The team assessed serum samples from 226 children from 18 countries for antibodies to H. pylori.
|31% of internationally adopted children had antibodies to H. pylori.|
They analyzed the serologic results in relation to age at adoption, site of residence prior to adoption, weight and height, and the presence or absence of anemia, diarrhea, or intestinal parasites.
The researchers found that 31% of internationally adopted children had antibodies to H. pylori.
They determined that the presence of H. pylori-antibodies was associated with residence in an orphanage prior to adoption, older age at adoption, and coinfection with intestinal parasites.
The team did not identify and direct effects on height or weight.
They did not find any associations with diarrhea or anemia.
Dr Laurie Miller's team concluded, "Internationally adopted children have a high incidence of exposure to H. pylori, as diagnosed serologically".
"Residence in an orphanage (compared with foster care), older age at adoption, and coinfection with intestinal parasites were more common among children seropositive for anti-H. pylori antibodies".
