| Popis: | A positive association between Helicobacter pylori antibodies and food allergy presenting with gastrointestinal symptoms has recently been reported. A subset of a H. pylori strain possesses an antigen, CagA, as a virulence factor. Anti-H. pylori and anti-CagA IgG titre have been determined in children with atopic dermatitis (AD) as the sole clinical manifestation of food allergy. In this study, thirty patients with AD as the sole clinical manifestation of food allergy were examined (group A). For comparative purposes, 30 patients affected by food allergy with gastrointestinal symptoms (group B) and 30 affected by atopic asthma (group C) were studied. Anti-H. pylori and anti-CagA immunoglobulin G (IgG) were determined in all individuals by means of the enzyme-linked immunosorbent assay. The anti-H. pylori IgG titre was significantly higher in group A and group B vs. group C (p 0.05). No significant difference in anti-CagA titre was found between the groups. These data demonstrate a positive association between H. pylori antibodies and AD as the sole manifestation of food allergy. Further investigations are needed to evaluate the cause-effect relationship between H. pylori seropositivity and AD. |
