Crohn's disease of the small bowel, complicated by primary biliary cirrhosis, Hashimoto thyroiditis, and Raynaud's phenomenon: favorable response of all disorders to adalimumab treatment.

We describe the case of a male patient suffering from long-lasting Crohn's disease of the small bowel who developed thyroiditis Hassimoto, Raynaud's phenomenon, and primary biliary cirrhosis, during the course of the underlying bowel disease. It is not clear whether these co-morbidities appeared coincidentally, or because they share some common immunopathogenetic mechanisms. In this patient, Crohn's disease favorably responded to the treatment with an anti-TNF-α agent (adalimumab).
