BACKGROUND: Anti-TNF agents are the only effective biological agents for the prevention of postoperative recurrence (POR) in Crohn's disease (CD). However, they are contraindicated or have been shown to fail in some patients. Although ustekinumab and vedolizumab were licensed for CD some years ago, data in this setting are scarce.; METHODS: All CD patients in whom ustekinumab or vedolizumab was prescribed for the prevention of POR within three months of ileocolonic resection with anastomosis were identified from the ENEIDA registry. The development of endoscopic, clinical and surgical POR was registered.; RESULTS: Forty patients were treated for the prevention of POR with ustekinumab and 25 were treated with vedolizumab. Eighty per cent had at least one risk factor for POR (prior resections, active smoking, perianal disease or penetrating disease behaviour). All the patients had been exposed to anti-TNF therapy. After a median follow-up of 17 and 26 months, the cumulative probability of clinical POR at 12 months after surgery was 32% and 30% for ustekinumab and vedolizumab, respectively. Endoscopic assessment within the first 18 months after surgery was available for 80% of the patients on ustekinumab and 70% for those on vedolizumab. The rate of endoscopic POR was 42% for ustekinumab and 40% for vedolizumab. One patient treated with ustekinumab and two with vedolizumab underwent a new intestinal resection.; CONCLUSIONS: Ustekinumab and vedolizumab seem to be effective in the prevention of POR in patients at high risk. Our results warrant controlled trials comparing these drugs with conventional therapies. Copyright © 2022. Published by Elsevier Ltd.

Background: Although the early outcomes of ulcerative colitis after a first course of corticosteroids are well known, data on long-term disease evolution in patients responding to a first corticosteroid course are scarce. Aims: To evaluate the long-term clinical evolution in ulcerative colitis patients responding to a first course of corticosteroids and to identify those factors associated with a poorer outcome. Methods: Retrospective review of 114 patients diagnosed with ulcerative colitis who responded to the first corticosteroid course, and did not start thereafter maintenance therapy with thiopurines were included. Results: Corticosteroids were prescribed because of a moderate (78%) or a severe flare (22%). All but two patients followed maintenance treatment with mesalazine after corticosteroid discontinuation. After a median follow-up of 83 months (7-156), 72% of patients suffered new relapses leading to corticosteroid reintroduction in 65% of patients. The earlier corticosteroids were introduced in the course of ulcerative colitis, the higher the risk of relapse and corticosteroid reintroduction. Thiopurines were started in 51%, and infliximab in 19%. Eleven percent of patients underwent colectomy. No predictors of thiopurine use or colectomy were found. Conclusions: Half of the ulcerative colitis patients responding to a first course of corticosteroids will require immunosuppressors mainly because of steroid-dependence.
