Special Issue Information

Dear Colleagues,

Treatment options and paradigms are shifting for ulcerative colitis. Recently licensed treatment options have increased the number of choices for clinicians and patients. Treatment targets are a topic of hot debate, and ultrasound assessment offers a new option of assessing ulcerative colitis. This Special Issue invites submissions addressing these new developments and guiding clinicians how to best approach these new challenges.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Clinical Medicine is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

JAK1 inhibitors have become an important addition to the therapeutic options for ulcerative colitis (UC), targeting key inflammatory pathways mediated by cytokines such as the IL-6 family, interferons, IL-2 family, IL-10 family, and G-CSF.

JAK1 inhibitors have become an important addition to the therapeutic options for ulcerative colitis (UC), targeting key inflammatory pathways mediated by cytokines such as the IL-6 family, interferons, IL-2 family, IL-10 family, and G-CSF. However, not all patients respond equally, and chronic inflammation persists in a subset of individuals. The variability in treatment response may reflect the heterogeneity of UC. Immune cells, epithelial cells, and stromal cells may have distinct contributions to disease pathogenesis. While JAK inhibitors were originally designed to target immune cells, their impact on non-immune cell types, such as epithelial and stromal cells, remains poorly understood. Investigating the mechanisms through which JAK1 inhibitors affect these diverse cellular populations and identifying the factors underlying differential responses is crucial to optimizing outcomes. This review explores the roles of immune, epithelial, and stromal cells in response to JAK1 inhibition and discusses potential strategies to improve treatment precision, such as predicting responders and identifying complementary therapeutic targets.

Acute severe ulcerative colitis is a medical emergency requiring inpatient treatment with intravenous steroids. Approximately one-third of patients do not respond to steroids sufficiently and require medical rescue therapy. Infliximab and cyclosporine are equally effective rescue agents, though infliximab is often preferred by clinicians for ease of use and greater familiarity. The use of cyclosporine is becoming more frequent, however, in patients previously exposed to infliximab. Those patients not exhibiting an adequate response to rescue therapy require colectomy. There is increasing interest in modified medical treatment to rescue the need for surgery. Janus kinase inhibitors may provide benefits when used alongside steroids from admission or as a rescue agent, but further randomised trials are needed to clearly establish their role. Intensified dosing of infliximab when used as a rescue therapy has shown mixed results but seems sensible in patients with low albumin and high disease burden. In this review, we describe the current established treatment pathways and report newer developments and evolving concepts that may in the future improve the care of patients with acute severe ulcerative colitis.
