Abstract:
Ixekizumab is a selective monoclonal antibody targeting interleukin-17A, approved for the treatment of chronic plaque psoriasis. It has rarely been associated with inflammatory bowel disease (IBD) in randomized trials only. We report a unique case of severe new-onset ulcerative colitis in a young male complicated by cytomegalovirus infection who was on ixekizumab therapy for plaque psoriasis. We recommend that clinicians should exercise caution before prescribing ixekizumab as it seems to induce and exacerbate IBD.

Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
