About this trial
In a real-world setting, this study systematically evaluates the clinical efficacy and safety of guselkumab (GUS) in the treatment of ulcerative colitis (UC), encompassing multi-dimensional outcomes including clinical remission, biochemical remission, endoscopic remission, histologic healing, and intestinal ultrasound changes.
Eligibility criteria
Qualifiers
Age ≥ 18 years.
Diagnosis of ulcerative colitis is established based on clinical manifestations, laboratory findings, colonoscopy, radiological imaging (CT or ultrasound), and histopathological examination.
Presence of moderate-to-severe disease activity, defined as a modified Mayo score (MMS) ≥ 5 points, accompanied by a rectal bleeding subscore (RBS) ≥ 1 and a Mayo endoscopic subscore (MES) ≥ 2.
Inadequate response or intolerance to at least one conventional therapy (5-aminosalicylates, corticosteroids, or immunosuppressants), as assessed by the investigator according to clinical practice.
Disqualifiers
Diagnosed with other intestinal diseases, such as Crohn's disease, intestinal tuberculosis, infectious colitis, ischemic colitis or other chronic intestinal inflammatory diseases;
If there is an active intestinal infection, and the fecal culture or pathogen test shows positive within 8 weeks before the study (including Clostridium difficile, cytomegalovirus, etc.), and the re-examination turns negative without any signs of persistent infection, a re-evaluation can be conducted.
Combined with severe infections, malignant tumors, severe liver and kidney dysfunction, or accompanied by active autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis, sarcoidosis, and Graves' disease that may interfere with disease assessment
Those who have undergone total colorectal resection or stoma surgery in the past and whose disease activity cannot be evaluated, or are expected to undergo major intestinal surgery during the study period;
