Background. Helicobacter pylori infection has been associated with an increased risk of thyroid diseases (TDs), although scientific evidence is conflicting. In the present study the relationship between TDs, including both autoimmune (AI) and non-autoimmune TD, and H. pylori infection was investigated. Methods: Data from records of patients undergoing upper endoscopy and histologically evaluated for H. pylori infection were retrieved. In addition to demographic information, the features of gastritis based on non-targeted biopsies collected from the antrum, angulus, and corpus were analyzed. The presence of H. pylori infection and atrophy and/or metaplasia and/or dysplasia in at least one gastric specimen was defined as a long-lasting H. pylori infection and the presence of a chronic-active gastritis as a current infection. Hashimoto's and Graves' diseases were included in the AITD group, and thyroid nodules, goiter, iatrogenic thyroid hypo/hyper function, and thyroidectomy in the non-autoimmune TD group. Results: A total of 8322 records from adult patients from Northern Sardinia, characterized by a similar genetic background, was analyzed. Participants were aged 18-93 years (females 5339, 64.1%), and more specifically, 562 (6.7%) had a diagnosis of AITD and 448 (5.4%) of non-autoimmune TD. A significant association between long-lasting H. pylori and AITD (OR 1.34; 95%CI 1.13-1.60) was found, irrespective of age, sex, body mass index, and smoking status, while it was not associated with non-autoimmune TD. Current H. pylori infection did not show significant ORs for AITD (OR 0.99; 95%CI 0.64-1.57) and non-autoimmune TD (OR 0.86; 95%CI 0.66-1.15). The association with long-lasting H. pylori infection was confirmed to be significant for both Hashimoto's thyroiditis and Graves' disease by multivariable regression analysis. Stratification according to sex revealed a significant association only for females (OR 1.39; 95%CI 1.12-1.72). Conclusions. Our results indicate that long-lasting H. pylori infection is associated with AITD in the female adult population of Northern Sardinia.

Abstract

Background. Helicobacter pylori infection has been associated with an increased risk of thyroid diseases (TDs), although scientific evidence is conflicting. In the present study the relationship between TDs, including both autoimmune (AI) and non-autoimmune TD, and H. pylori infection was investigated. Methods: Data from records of patients undergoing upper endoscopy and histologically evaluated for H. pylori infection were retrieved. In addition to demographic information, the features of gastritis based on non-targeted biopsies collected from the antrum, angulus, and corpus were analyzed. The presence of H. pylori infection and atrophy and/or metaplasia and/or dysplasia in at least one gastric specimen was defined as a long-lasting H. pylori infection and the presence of a chronic-active gastritis as a current infection. Hashimoto's and Graves' diseases were included in the AITD group, and thyroid nodules, goiter, iatrogenic thyroid hypo/hyper function, and thyroidectomy in the non-autoimmune TD group. Results: A total of 8322 records from adult patients from Northern Sardinia, characterized by a similar genetic background, was analyzed. Participants were aged 18-93 years (females 5339, 64.1%), and more specifically, 562 (6.7%) had a diagnosis of AITD and 448 (5.4%) of non-autoimmune TD. A significant association between long-lasting H. pylori and AITD (OR 1.34; 95%CI 1.13-1.60) was found, irrespective of age, sex, body mass index, and smoking status, while it was not associated with non-autoimmune TD. Current H. pylori infection did not show significant ORs for AITD (OR 0.99; 95%CI 0.64-1.57) and non-autoimmune TD (OR 0.86; 95%CI 0.66-1.15). The association with long-lasting H. pylori infection was confirmed to be significant for both Hashimoto's thyroiditis and Graves' disease by multivariable regression analysis. Stratification according to sex revealed a significant association only for females (OR 1.39; 95%CI 1.12-1.72). Conclusions. Our results indicate that long-lasting H. pylori infection is associated with AITD in the female adult population of Northern Sardinia.
