BACKGROUND AND AIMS: This observational study assessed the long-term clinical benefit of infliximab (IFX) in 614 consecutive patients with Crohn's disease (CD) from a single centre during a median follow-up of 55 months (interquartile range (IQR) 27-83). METHODS: The primary analysis looked at the proportion of patients with initial response to IFX who had sustained clinical benefit at the end of follow-up. The long-term effects of IFX on the course of CD as reflected by the rate of surgery and hospitalisations and need for corticosteroids were also analysed. RESULTS: 10.9% of patients were primary non-responders to IFX. Sustained benefit was observed in 347 of the 547 patients (63.4%) receiving long-term treatment. In 68.3% of these, treatment with IFX was ongoing and in 31.7% IFX was stopped, with the patient being in remission. Seventy patients (12.8%) had to stop IFX due to side effects and 118 (21.6%) due to loss of response. Although the yearly drop-out rates of IFX in patients with episodic (10.7%) and scheduled treatment (7.1%) were similar, the need for hospitalisations and surgery decreased less in the episodic than in the scheduled group. Steroid discontinuation also occurred in a higher proportion of patients in the scheduled group than in the episodic group. CONCLUSIONS: In this large real-life cohort of patients with CD, long-term treatment with IFX was very efficacious to maintain improvement during a median follow-up of almost 5 years and changed disease outcome by decreasing the rate of hospitalisations and surgery.

Background: Infliximab (IFX) treatment induces mucosal healing (MH) in patients with Crohn's disease (CD) but the impact of MH oil the long-term outcome of IFX treatment in CID is still debated. Methods: We studied MH during long-term treatment with IFX in 214 CID patients. A total of 193 patients (85.5%) responded to induction therapy and 31 patients (14.5%) were primary nonresponders. They underwent lower gastrointestinal (GI) endoscopy within a median of 0.7 months (interquartile range [IQR] 0.1-6.9) prior to first IFX and after a median of 6.7 months (IQR 1.4-24.6) after start of IFX and were further analyzed. The relationship between the outcome of IFX treatment long-term and MH was studied. Results: MH was observed in 67.8% of the 183 initial responders (n = 124), with 83 patients having complete healing (45.4%) and 41 having partial healing (22.4%). Scheduled IFX treatment from the start resulted in MH more frequently (76.9% MH rate) than episodic treatment (61.0% MH rate; P = 0.0222, odds ratio [OR] 2.14, 95% confidence interval [CI] 1.11-4.12). Concomitant treatment with corticosteroids (CS) had a negative impact on MH (37.9% in patients with CS versus 63.2% in patients without CS; P = 0.021, OR 0.36, 95% CI 0.16-0.80). MH was associated with a significantly lower need for major abdominal surgery (MAS) during long-term follow-up (14.1% of patients with MH needed MAS versus 38.4% of patients Without MH: P < 0.0001). Conclusions: MH induced by long-term maintenance IFX treatment is associated with an improved long-term outcome of the I disease especially with a lower need for major abdominal surgeries. [less ▲]

Background and aims: Infliximab (IFX) has been shown efficacious for moderate-to-severe ulcerative colitis (UC), but data on long-term efficacy are tacking. We investigated long-term outcome including colectomy rates in outpatients treated with IFX for refractory UC in a single referral centre, and evaluated if predictors could be identified. Methods: The first 121 outpatients (median age 38.0 years) with refractory UC treated with IFX were included. The primary outcome was colectomy-free survival. Secondary measures were sustained clinical response and serious adverse events. Results: From the 81 patients (67%) with an initial clinical response to IFX, 68% had a sustained clinical response. No independent predictors of sustained clinical response could be identified. Over a median (IQR) follow-up period of 33.0 (17.0-49.8) months, 21 patients (17%) came to colectomy. Independent predictors of colectomy were absence of short-term clinical response [Hazard ratio 10.8 (95% Cl 3.5-32.8), p < 0.001], a baseline CRP level >= 5 mg/L [Hazard ratio 14.5 (95% Cl 2.0-108.6), p=0.006] and previous IV treatment with corticosteroids and/or cyctosporine [Hazard ratio 2.4 (95% Cl 1.1-5.9), p=0.033]. Six patients developed a serious infection, three a malignancy, two a post-operative complication and one patient died (suicide). Conclusions: With a median follow-upof 33.0 months after start of IFX, 17% of patients with refractory UC needed colectomy, while sustained clinical response was present in 68% of initial responders.
