ABSTRACT Clinical significance of autoantibodies to parietal cells (PCA) in patients with autoimmune thyroid diseases (ATD) remains contradictory. AIM: To characterize the frequency of PCA in patients with ATD; to clarify the role of gender and age in PCA positivity; to analyze the association of PCA with gastric or haematologic symptoms and with the levothyroxine dose required to achieve a serum TSH level within the normal range in treated Hashimoto’s thyroiditis (HT) patients. PATIENTS AND METHODS: PCA were measured using ELISA in 137 HT patients, divided into tree subgroups according to the thyroid function: group I included subjects with normal thyroid function; group II included patients with hypothyroidism, in group III were enrolled subjects treated with levothyroxine (LT4). We also studied the PCA positivity in 14 patients with active Graves’ disease and in 23 healthy controls. RESULTS: PCA positivity was found in 51 patients with autoimmune thyroid diseases, with an overall prevalence of 33.8%. No significant differences in PCA were observed between the groups of HT patients. The frequency of PCA in both genders was similar and there were no difference depending on age. In 7.3% of HT patients in different stages of disease we found clinically relevant gastric and/or haematologic symptoms; in 70% of them PCA were positive (OR = 5.5; 95% CI: 1.2 - 28.4; p = 0.009). PCA positive hypothyroid HT patients required higher LT4 doses than PCA negative (1.46 μg/kg vs 1.24 μg/kg, p = 0.04). CONCLUSIONS: PCA may be present in different stages in HT patients; this does not depend on the severity of disease. PCA concentrations may predict symptoms of atrophic gastritis in patients with Hashimoto’s thyroiditis. PCA positive HT patients require higher replacement doses of LT4. Presence of anemia, particularly microcytic anemia, was suggestive of undiagnosed atrophic gastritis.

The human microbiota is an integral component in the maintenance of health and of the immune system. Microbiome-wide association studies have found numerous diseases associated to dysbiosis. Studies are needed to move beyond correlations and begin to address causation. Autoimmune thyroid diseases (ATD) are one of the most common organ-specific autoimmune disorders with an increasing prevalence, higher than 5% worldwide. Most frequent manifestations of ATD are Hashimoto’s thyroiditis and Graves’ disease. The exact etiology of ATD remains unknown. Until now it is not clear whether bacterial infections can trigger ATD or modulate the efficacy of treatment and prognosis. The aim of our review is to characterize the microbiota and in ATD and to evaluate the impact of dysbiosis on treatment and prognosis. Moreover, variation of gut microbiome has been associated with thyroid cancer and benign nodules. Here we will characterize the microbioma in benign thyroid nodules, and papillary thyroid cancer to evaluate their implications in the pathophysiology and progression.
