title: Wilson's Disease and Ulcerative Colitis in the Same Patient: Just A Coincidence? A Case Report and Literature Review.
abstract: Ulcerative Colitis (UC) is a chronic relapsing inflammatory bowel disease (IBD). Wilson's disease (WD) is a disorder of copper (Cu) metabolism due to inherited mutations in a gene encoding a putative Cu-transporting P-type ATPase, with a heterogeneous clinical presentation that includes hepatic, neurological, or psychiatric symptoms. The case of a 17-year-old female that presented with severe liver failure, three years after UC onset, and in which diagnosis of WD was established is reported. We review the literature and discuss the possible association between the two rare diseases. Although evidence of a common genetic background between UC and WD has not been described, high Cu serum level is present in both diseases. Cu is one of the trace elements necessary for antioxidant defenses during inflammatory processes, affecting the production of free radicals of oxygen and the levels of cellular antioxidants. The presence of both entities in the same patient may suggest abnormal metabolism of Cu or be just a coincidence.
