The Mayo Endoscopic Subscore (MES) is commonly used for quantifying disease activity, but it has several weaknesses. Numerous new endoscopic indices have been developed but none of these have been widely implemented, likely due to limited feasibility. The primary objective of this study was thus to develop a simple, reliable, endoscopic index for ulcerative colitis. Secondary objectives were to evaluate and compare the MES, the Ulcerative Colitis Endoscopic Index of Severity (UCEIS), and the Ulcerative Colitis Colonoscopic Index of Severity (UCCIS), as well as examining the agreement between full colonoscopy and sigmoidoscopy.</p><p><strong>Methods: </strong>Consecutive adult ulcerative colitis patients had their routine colonoscopies video recorded, each edited into five shorter segment-specific video sequences. In parallel, blood, fecal, and mucosal samples were collected, together with data on symptoms and quality-of-life. The video sequences were scored by three gastroenterologists and one resident gastroenterologist according to a form comprising six endoscopic disease activity descriptors and an overall endoscopic disease severity assessment.</p><p><strong>Results: </strong>One hundred unique video sequences from twenty patients were each evaluated three times by four assessors, generating a total of 7200 unique segment-specific data-points for the six descriptors and 1200 unique assessments of overall endoscopic disease severity. The intra- and interobserver agreement for the individual descriptors were overall <i>moderate</i> to <i>very good</i>. The MES, UCEIS, and UCCIS performed similarly with the latter being slightly superior in terms of reliability and correlation to biomarkers of disease activity. The descriptor <i>vascular pattern</i> was the best discriminator at the lower end of the disease activity spectrum, whereas the descriptor <i>ulcers</i> was the best at the medium to high end. These two descriptors were combined into a new index, the Simple Endoscopic Score for Ulcerative Colitis (SES-UC), which displayed similar levels of reliability and accuracy as the established indices. Finally, comparison of sigmoidoscopy and colonoscopy showed that up to 38% of patients had their most inflamed segment located proximally to the sigmoid colon.</p><p><strong>Conclusions: </strong>We propose a new simplified endoscopic index for ulcerative colitis, the SES-UC, which is based on the two descriptors <i>vascular pattern</i> and <i>ulcers</i>. The performance of the SES-UC was similar to, and in some regards better than, that of the established indices (MES, UCEIS, and UCCIS). This together with its simplicity makes SES-UC a candidate index for use in clinical practice as well as in clinical studies.</p>","PeriodicalId":73085,"journal":{"name":"Frontiers in gastroenterology (Lausanne, Switzerland)","volume":"3 ","pages":"1468394"},"PeriodicalIF":0.0,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12952406/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147446202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review examines the complex involvement of innate immune cells in IBD, emphasizing their interactions with environmental factors and the gut microbiome. We highlight the importance of microbial dysbiosis and impaired intestinal barrier function in disease pathogenesis, and the role that innate immune cells play not only as first responders, but also as key players in maintaining intestinal barrier integrity and gut microbiome. This review provides a comprehensive summary of the role that innate immune cells play in IBD pathogenesis with emphasis on the increasingly recognized role of the gut microbiome.

The life-threatening nature of this condition requires clinicians to make prompt diagnoses and take rapid action, either directing patients towards surgical interventions or medical management. Failure to treat ASUC may lead to toxic dilation of the colon, hemorrhage, or sepsis. Current algorithms suggest the use of intravenous (IV) corticosteroids upon diagnosis, with transition to oral corticosteroids, calcineurin inhibitors or tumor necrosis factor (TNF) inhibitors upon reduction of severe symptoms for candidates deemed to be amenable to medical management. Within these classes, TNF inhibitors such as Infliximab (IFX) have proven to be the most safe, efficacious, and tolerable for patients. While IFX has much data supporting its benefits in achieving short term remission, there are still high rates of long-term need for colectomy and failure to maintain remission. This is due to interactions between the inflamed gastrointestinal tract, the increased metabolic activity seen in ASUC, and intrinsic pharmacodynamic properties of IFX. Certain novel studies suggest that Janus Kinase (JAK-STAT) inhibitors such as Tofacitinib and Upadacitinib are potent agents to salvage clinical remission achieved by IFX, upon its failure. Here we discuss methods to optimize the dosing of IFX to maximize its efficacy, while exploring recent work done on the safety and efficacy of JAK-STAT inhibitors as a salvage therapy, therefore suggesting a novel treatment algorithm to improve clinical outcomes in medically managed ASUC patients.</p>","PeriodicalId":73085,"journal":{"name":"Frontiers in gastroenterology (Lausanne, Switzerland)","volume":"3 ","pages":"1488288"},"PeriodicalIF":0.0,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12952307/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147446154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
