[Antibodies to Yersinia enterocolitica in immunogenic thyroid diseases].

[Article in German]

Abstract

In 1976 Shenkman et al. revealed that in patients with thyroid disorders antibodies against Yersinia enterocolitica could be demonstrated in increased frequency. In 1983 Ingbar et al. first established that the gram-negative bacterium Yersinia enterocolitica shows on its surface saturable binding sites for thyrotropin (TSH). If such binding sites resemble immunologically human TSH receptors this would indicate that TSH receptor antibodies could be produced in selected individuals having been infected with bacteria showing TSH receptors. The aim of our study was to compare the incidence of antibodies against Yersinia enterocolitica in two groups of thyroid disorders which are either immunogenic (Graves' disease and Hashimoto thyroiditis) or non-immunogenic (toxic adenomas, endemic goitre). In our series of 111 patients antibodies against Yersinia enterocolitica were demonstrated in a significantly higher percentage (36.3%) in patients suffering from immunogenic than in patients with non-immunogenic thyroid disorders (19.6%). The antibody titres were mainly directed towards Yersinia subtypes 8 and 3. It may, therefore, be assumed that the gram-negative bacterium Yersinia enterocolitica may have an active part in triggering immunogenic thyroid diseases such as Graves' disease or Hashimoto thyroiditis.
