[Serum levels of IgE in children with invasive amebiasis]. / Niveles de IgE sérica en niños con amibiasis invasora.

In order to determine whether an elevation of the IgE serum level exist in children with invasive amebiasis when compared with a control group, a prospective, observational and descriptive study was performed on 20 patients from the problem group and 21 from a control group, where the possibility of other causes which could raise the IgE levels were dismissed. This antibody was measured in serum and compared with the reported levels of mexican and foreign populations. A notable elevation of the IgE level was found in the studied groups, without any significant differences between them. It wasn't demonstrated that the serum level is as high as immunological response against E. histolytica.
