[Seroprevalence of Helicobacter pylori among the child population of Ecuador].
OBJECTIVE
To determine the prevalence of anti-Helicobacter pylori IgG antibodies among the children population of Ecuador and the possible relation with the presence of recurring gastrointestinal symptoms.


METHODS
Children randomly selected from different geographical areas were included and the presence of serum antibodies was tested using the enzyme-linked immunosorbent assay (ELISA). The gastrointestinal symptoms between patients with serum antibodies and those without serum antibodies were analyzed, excluding children who had not been treated for intestinal parasites before.


RESULTS
A total of 257 children was studied, with a mean age of 8.3 years (age range between 6 months and 16 years). A seroprevalence of 63.03% was found, the most affected being the children from the Andes mountains, in the range 0 to 4 years old. A significant relation was found between the presence of anti-Hp antibodies and symptoms (p=0.001).


CONCLUSIONS
There is a high prevalence of anti-Helicobacter pylori IgG antibodies among the Ecuadorian children, related with the presence of recurring gastrointestinal symptoms.
