Diagnosis and treatment of tuberculosis

Summary Background Phase III trials have demonstrated the efficacy and safety of ustekinumab in ulcerative colitis (UC), but few real‐life long‐term data are currently available. Aims To assess the real‐world effectiveness and safety of ustekinumab in patients with UC. Methods From January to September 2019, all consecutive patients with active UC treated with ustekinumab in a GETAID centre were included. Patients were evaluated at week 52. Remission was defined as a partial Mayo Clinic score ≤2. Results We included 103 patients with UC (62 men; mean age: 41.2 ± 16.2 years; 52% pancolitis E3) with an insufficient response to immunosuppressants, anti‐TNFs and/or vedolizumab. At week 52, 45 (44%) patients had discontinued ustekinumab mainly due to lack of effectiveness (n = 41). The cumulative probabilities of ustekinumab persistence were 96.1%, 81.6%, 71.7% and 58.4% after 3, 6, 9 and 12 months respectively. The overall steroid‐free clinical remission rate at week 52 was 32% of whom 71% had subscores of null for rectal bleeding and stool frequency. Ten patients underwent colectomy within a median of 6.7 [4.3‐10.6] months. Adverse effects were observed in 15 (16.9%) patients; 4 (4.5%) were severe, including one patient who died from a myocardial infarction. Conclusion After 52 weeks, over one‐half of patients with refractory UC were still treated by ustekinumab and one‐third were in steroid‐free clinical remission.
