RESUMO

Infections attributed to Helicobacter pylori [H. pylori] involve almost half of the world's population. One of the effects is auto-antibody induction and cross-reaction with numerous proteins in the body. As a result of its widespread prevalence and importance, this study evaluates the associations between H. pylori and thyroid auto-antibodies. This study enrolled 100 patients who were candidates for gastroesophageal endoscopy that referred to the Yazd Gastrointestinal Clinic. Patients underwent the following laboratory analyses: urease test, anti-H. pylori [IgG], TSH, T4, T3 and thyroid auto-antibodies [anti-thyroglobulin, anti-thyroid peroxides]. Patients were divided into two groups of H. pylori positive and negative according to the results of the anti-H. pylori IgG and urease tests. The level of thyroid auto-antibodies and thyroid function tests were compared between groups. Data were analyzed with chi-square and t-tests. SPSS software version 17 was used for data analysis. Overall, 61% of patients were H. pylori positive. The mean anti-Thyroid peroxidase level in the H. pylori positive group was significantly more than the negative group [p<0.01]. In addition, 19.7% of H. pylori positive patients and 5.1% of H. pylori negative patients had positive anti-TPO levels, which the difference between both groups was significant [p<0.04]. There was no significant difference in thyroid function between the two groups. Although no significant difference in thyroid function was seen in the two groups more patients tested positive for anti-TPO levels in the H. pylori positive group, which was suggestive of thyroid auto-antibody induction by H. pylori.
