Comparison of chronic autoimmune urticaria with chronic idiopathic urticaria

Abstract

The authors observed a relationship between autoimmune urticaria and autoimmune thyroiditis. The results strengthen the possibility of cross-reactivity being triggered between CagA plus H. pylori strains and some other organ-specific autoimmune diseases such as autoimmune urticaria and autoimmune thyroiditis. This indicates a possible role of H. pylori in triggering autoimmune urticaria in at least a select group of patients.
