Helicobacter pylori; organ-specific autoantibodies
Background. We compared the prevalence of organ-specific autoantibodies in a group of Helicobacter pylori infected children and a group of uninfected children and investigated the relationship between the presence of relevant autoantibodies and the status of the target organs. Patients and Methods. One hundred and twenty-four children with dyspepsia (54 boys, 70 girls; mean age 10.5 years; range 4-19) underwent gastroscopy: 56 had H. pylori infection (31 girls, 25 boys), while 68 (37 girls and 31 boys), were H. pylori-negative. All sera were tested for the presence of: parietal cell autoantibodies (PCA), intrinsic factor autoantibodies (IFA), microsomial autoantibodies, thyroglobulin autoantibodies, islet cell autoantibodies, glutamic acid decarboxylase autoantibodies, adrenal cortex autoantibodies, steroid-producing cell autoantibodies; gastrin, pepsinogen A, pepsinogen C and anti-H. pylori antibodies. The histological features and the ureA and cagA genes were also considered. Results. The frequency of organ-specific autoantibodies was higher in patients with H. pylori infection than in uninfected patients (chi(2)-test p < .0001). Specifically gastric autoantibodies were significantly higher: seven of the 56 H. pylori-positive children were PCA-positive and one was IFA-positive (chi(2)-test p = .0004). The presence of autoantibodies was not associated with any clinical or biohumoral signs of disease. Conclusions. Our study detected a relationship between H. pylori infection in childhood and the presence of organ-specific autoantibodies unassociated with any clinical or biohumoral signs of disease. Helicobacter pylori infection in childhood could trigger the onset of clinical autoimmune gastritis, and/or other clinical autoimmune diseases.
