Helicobacter Pylori Infection: Association with Hashimoto’s Thyroiditis

Auto immune thyroid diseases (ATDS) are represented, essentially, by Hashimoto’s thyroiditis (HT), grave’s disease and atrophic thyroiditis [1]. Atypical marker of HT is the presence of autoantibodies against thyroglobulin and thyroid peroxidase (TPO Abs) [2]. Both genetic and environmental factors are involved in the pathogenesis of ATDS [3]. Some bacteria and viruses are suspected of being able to mimic the antigenic profile on the thyroid membrane and play an important role in the onset of auto immune diseases [4,5].
