Wernicke’s Encephalopathy in a Patient With Crohn’s Disease: A Case Report

Abstract

The inflammatory bowel diseases (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), are chronic inflammatory disorders of the intestine. Both are associated with intestinal and extra-intestinal manifestations (EIM). EIM are usually related to intestinal disease activity and may precede or develop concurrently with intestinal symptoms. Although they are well documented, the association of CD with neurological and neuromuscular involvement is rare and controversial, with sporadic and contradictory data regarding its prevalence and spectrum. Neurological involvement can affect the central or peripheral nervous system, with thrombotic events being the most frequent complication. Wernicke's encephalopathy (WE) is one of the neurological complications that occurs in the general population with a clinical prevalence ranging from 0.04% to 0.13%. Although no specific data exists for IBD patients, it is imperative for clinicians to be vigilant and consider the possibility of this condition even with mild neurological symptoms and to administer vitamin B1 promptly before attempting any biological assessment. Timely treatment is essential to avoid irreversible damage or even the death of the patient.We report herein a challenging case of WE in CD and we discuss the literature.
