Chronic inflammatory demyelinating polyradiculoneurophathy and Graves' disease in an adolescent with Crohn's disease

Concomitant Thyroid Disorders and Inflammatory Bowel Disease: A Literature Review

The aim of this report was to review and summarize the literature on cases of concomitant inflammatory bowel disease (IBD) and thyroid diseases. We included the following previous case reports of concomitant IBD and thyroid diseases: 16 cases of ulcerative colitis (UC) and Graves' disease (GD), 3 cases of Crohn's disease (CD) and GD, 10 cases of CD and Hashimoto's thyroiditis (HT), 4 cases of IBD and subacute thyroiditis (SAT) or SAT-like symptoms, and 13 cases of IBD (12/13 cases were CD) and amyloid goiter. There might be no obvious differences of prevalence of thyroid dysfunction (hyper- or hypothyroidism), GD, and thyroid cancer between IBD patients and general populations. However, concomitant UC and HT might be relatively common in patients with multiple autoimmune disorders, and AG is one of the complications with CD patients. There might be no obvious differences of fatal prognoses between IBD patients with thyroid diseases and patients with thyroid diseases without IBD.

Autoimmune thyroid disease (Graves' disease and hashimoto's thyroiditis) in two patients with Crohn's disease: case reports and literature review

An increased prevalence of the association between autoimmune thyroid diseases and ulcerative colitis has been suggested, however, not with Crohn's disease, as only 7 cases of thyroid disease coexisting with Crohn's disease have been reported. Herein, we describe 2 patients with Crohn's disease complicated with Graves' disease or autoimmune thyroiditis, and also review other cases with those complications. Some immunological processes are suggested to be implicated in the pathogenesis of this association, however, the exact mechanism remains unclear.
