This is the second of a series of two articles reporting the European Crohn’s and Colitis Organisation [ECCO] evidence-based consensus on the management of adult patients with ulcerative colitis [UC]. The first article is focused on medical management and the present article addresses medical treatment of acute severe ulcerative colitis [ASUC] and surgical management of medically refractory UC patients, including preoperative optimization, surgical strategies, and technical issues. The article provides advice for a variety of common clinical and surgical conditions. Together, the articles represent an update of the evidence-based recommendations of the ECCO for UC.
Background and aims
Dual Targeted Therapy (DTT) has been proposed as a novel therapeutic strategy for the management of complicated patients with Inflammatory Bowel Diseases (IBD). Our aim was to investigate the safety and effectiveness of this approach in a real-life setting.
Methods
We retrospectively extracted data from IBD patients receiving DTT in Italian IBD referral centres. Baseline characteristics, clinical activity of intestinal and extraintestinal disease and C-reactive proteins levels were recorded. All adverse events were reported. Clinical effectiveness, biochemical remission and safety of DTT were investigated.
Results
Sixteen patients were identified; indications for DTT were: “active IBD” or “active EIM” despite ongoing biological therapy. The most commonly used DTT were: vedolizumab + ustekinumab (3 patients) and vedolizumab + adalimumab (3 patients). Clinical response of intestinal or extraintestinal symptoms, according to the indication for DTT, was reported by all patients by the end of the induction. Four patients discontinued DTT during follow-up. Three patients experienced an adverse event; no serious adverse event was reported.
Conclusions
DTT seems to be an effective and safe treatment and may represent an appealing therapeutic strategy for the management of complicated IBD patients.
Ulcerative colitis (UC) is a chronic relapsing disorder of the colonic tract, characterized by a dysregulated innate and adaptive immune response to gut microbiota that contributes to the perpetuation of intestinal inflammatory processes. The Interleukin (IL) 23/IL17 axis has been reported to play a key role in UC pathogenesis promoting Th17 cells and cytokines-related immune response. Recently, the blockade of IL23/IL17 pathways has been raised enormous interest in the treatment o several chronic inflammatory disorders. In this review, we summarize the emerging results from clinical trials that evoked both promise and discouragement in IL23/IL17 axis in the treatment of UC. Targeting IL23 p40 through Ustekinumab results safe and effective to induce and maintain clinical remission, low inflammatory indexes, mucosal healing, and a better quality of life. Studies targeting IL23 p19 through Mirikizumab, Risankizumab, Brazikumab and Guselkumab are still ongoing. To date, no clinical studies targeting IL17 pathway are ongoing in UC. IL-17 targeting is thought to have a context-dependent biological effect, based on whether cytokine is selectively targeted or if its function is dampened by the upstream block of IL23.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
