Moreover, an attempt to introduce a novel customized method of histopathological evaluation could be carried out.\n* To correlate the clinical and endoscopic follow up data of patient on treatment with the histopathological evaluation. This will be done in order to evaluate the possible predictive effect of histopathological evaluation on the disease course and hence as a tool to drive possible modification of the therapeutic choices', 'detailedDescription': 'Ulcerative colitis (UC) is a chronic inflammatory disease of idiopathic origin affecting the rectum and colon. Patients classically manifest with rectal bleeding, diarrhea, tenesmus, urgency, abdominal pain, weight loss, fever, and malaise. Pathologically, it is defined by a continuous mucosal inflammation of the rectum and a variable extent of the colon, without granulomas on mucosal biopsies. The course of UC is characterized by periods of remission and relapsing. In patients with extensive or severe inflammation, acute complications such as severe bleeding and toxic megacolon, which can lead to perforation, may occur. Patients newly diagnosed with UC have a 5-year risk of colectomy of 10-35%, and ultimately, persistent and extensive inflammatory activity increases the long-term risk of dysplasia and colorectal cancer.\n\nWhile treatment of patients with UC is primarily aiming to achieve clinical remission (CR) and endoscopic remission (ER), there is now interest in targeting histological healing (HH) in addition to CR, as symptoms may not reliably correlate with histological activity. Moreover, ER is not always an accurate indicator of histological healing. Furthermore, histological changes tend to lag behind CR after treatment. Accordingly, histological remission may be considered as an independent predictor of clinical relapse better than endoscopic appearances.\n\nThe Selecting Therapeutic Targets in Inflammatory Bowel Disease (STRIDE) II committee introduced a treat-to-target approach and proposed that the therapeutic target in UC should include clinical and patient-reported outcome remission, alongside endoscopic remission, with Mayo endoscopic subscore of 0. Histologic remission is not a formal target of medical therapy, but it is considered an "adjunct to endoscopic remission to represent a deeper level of healing.\n\nHowever, Various studies have elucidated that histologic remission serves as a distinct treatment objective from endoscopic remission, offering a superior prediction of clinical remission. In few studies, histological remission seems to correlate with long-term clinical remission, better clinical outcomes, and a lower risk of intestinal dysplasia, even though significant data are still lacking.\n\nCurrently, about 30 histologic scoring systems in UC have been described and used for quantitative assessment, but 3 have recently undergone scientific validation namely the Gobeos score (GS), Nancy Index (NI) and Robarts Histopathologic Index (RHI). For histologic measurements of disease activity to affect clinical decision making, pathologists should agree upon which standardized features to report and the definitions of these parameters.\n\nGS evaluates all aspects of mucosal injury seen in UC including crypt architecture, lamina propria chronic inflammation, lamina propria eosinophils, lamina propria neutrophils, intraepithelial neutrophils, crypt destruction, and surface epithelial injury.\n\nThe RHI was developed based on several reproducible features included in the final index (lamina propria chronic inflammation, lamina propria neutrophils, neutrophils in the epithelium, and surface epithelial injury). Although the RHI was specifically designed to be responsive and reproducible, it requires assessment of 4 features to arrive at a calculated score, which may reduce its clinical usefulness.\n\nThe NI is a stepwise 5-item index that evaluates lamina propria chronic inflammation (defined as lymphocytes, plasma cells, and eosinophils), neutrophilic inflammation, and ulcers.\n\nIt is unclear which of these histologic scoring indices is most useful in clinical practice. In this context, it is important that pathologists to include important, reproducible histologic features in a pathology report that could be correlated better with clinical management. In addition, the development and validation of novel histologic scoring systems, better correlate with CR and ER, should be tried out.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': '\\- The study will include 60 cases of patients diagnosed clinically and pathologically as ulcerative colitis and received therapeutic regimen at Department of Internal medicine ,Gastroenterology unit .- Biopsies of those patients will be reevaluated using the three histopathological indices; Gobeos score, Nancy Index and Robarts Histopathologic Index on hematoxylin and eosin stained slides', 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Adult patients \\>18 years diagnosed with ulcerative colitis based on standard clinical, endoscopic, and histological criteria\n\nExclusion Criteria:\n\n* Patients lost to follow-up and those with insufficient data'}, 'identificationModule': {'nctId': 'NCT06918093', 'briefTitle': 'A Comparative Evaluation of Different Histopathological Indices of Mucosal Healing in Ulcerative Colitis', 'organization': {'class': 'OTHER', 'fullName': 'Assiut University'}, 'officialTitle': 'A Comparative Evaluation of Different Histopathological Indices of Mucosal Healing in Ulcerative Colitis, and Their Correlation With Clinical Follow-up Data', 'orgStudyIdInfo': {'id': 'UC STUDY'}}, 'contactsLocationsModule': {'centralContacts': [{'name': 'Aya Mahmoud, demonestrator', 'role': 'CONTACT', 'email': 'AyaMahmoudMohamed@aun.edu.eg', 'phone': '+201159392242'}, {'name': 'Noha Abd El Rahim, Assistant Professor', 'role': 'CONTACT', 'email': 'nohah@aun.edu.eg', 'phone': '+201007509759'}], 'overallOfficials': [{'name': 'Thanaa Sotouhy, Professor', 'role': 'STUDY_DIRECTOR', 'affiliation': 'Assiut University'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Assiut University', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Principal Investigator', 'investigatorFullName': 'Aya Mahmoud Mohamed', 'investigatorAffiliation': 'Assiut University'}}}}
