The incidence rate of psoriasis induced by anti-TNF therapy is higher in women and in smokers/former smokers. In most patients, skin lesions were controlled with topical steroids. More than half of patients switching to another anti-TNF agent had recurrence of psoriasis. In most patients, the anti-TNF therapy could be maintained.

Background The development program (UNIFI) has shown promising results of ustekinumab in ulcerative colitis (UC) treatment that should be confirmed in clinical practice. Aims To evaluate the durability, effectiveness and safety of ustekinumab in UC in real-life. Methods Patients included in the prospectively maintained ENEIDA registry who received at least one intravenous dose of ustekinumab due to active UC [Partial Mayo Score (PMS) >2] were included. Clinical activity and effectiveness were defined based on PMS. Short-term response was assessed at week 16. Results A total of 95 patients were included. At week 16, 53% of patients had response (including 35% of patients in remission). In the multivariate analysis, elevated serum C-reactive protein was the only variable significantly associated with lower likelihood of achieving remission. Remission was achieved in 39% and 33% of patients at weeks 24 and 52, respectively. Thirty-six percent of patients discontinued the treatment with ustekinumab during a median follow-up of 31 weeks. The probability of maintaining ustekinumab treatment was 87% at week 16, 63% at week 56, and 59% at week 72; primary failure was the main reason for ustekinumab discontinuation. No variable was associated with risk of discontinuation. Three patients reported adverse events; one of them had a fatal severe SARS-CoV-2 infection. Conclusions Ustekinumab is effective both in the short and the long-term in real-life, even in a highly refractory cohort. Higher inflammatory burden at baseline correlated with lower probability of achieving remission. Safety was consistent with the known profile of ustekinumab.

Summary Background Effectiveness of vedolizumab in real world clinical practice is unknown. Aim To evaluate the short and long‐term effectiveness of vedolizumab in patients with inflammatory bowel disease (IBD). Methods Patients who received at least 1 induction dose of vedolizumab were included. Effectiveness was defined based on Harvey‐Bradshaw index (HBI) in Crohn's disease (CD) and Partial Mayo Score (PMS) in ulcerative colitis (UC). Short‐term response was assessed at week 14. Variables associated with short‐term remission were identified by logistic regression analysis. The Kaplan‐Meier method was used to evaluate the long‐term durability of vedolizumab treatment. Cox model was used to identify factors associated with discontinuation of treatment and loss of response. Results 521 patients were included (median follow‐up 10 months [interquartile range 5‐18 months]). At week 14, 46.8% had remission and 15.7% clinical response. CD (vs UC), previous surgery, higher CRP concentration and disease severity at baseline were significantly associated with impaired response. The rate of vedolizumab discontinuation was 37% per patient‐year of follow‐up (27.6% in UC and 45.3% in CD, P < 0.01). CD (vs UC), anaemia at baseline, steroids during induction and CRP concentration were associated with lower durability of treatment. Seven per cent of patients developed adverse events, infections being the most frequent. Conclusions Over 60% of IBD patients respond to vedolizumab. Many patients discontinue treatment over time. CD and disease burden impair both short‐ and long‐term response. Vedolizumab seems to be safe in clinical practice.

IBD is a highly prevalent disorder in our region, reaching the incidence of CD similar to the figures provided for Northern Europe. Changes in IBD localization, behavior, and age at diagnosis were documented during the period 2000-2012.

Background The effectiveness of the switch to another anti–tumor necrosis factor (anti-TNF) agent is not known. The aim of this study was to analyze the effectiveness and safety of treatment with a second and third anti-TNF drug after intolerance to or failure of a previous anti-TNF agent in inflammatory bowel disease (IBD) patients. Methods We included patients diagnosed with IBD from the ENEIDA registry who received another anti-TNF after intolerance to or failure of a prior anti-TNF agent. Results A total of 1122 patients were included. In the short term, remission was achieved in 55% of the patients with the second anti-TNF. The incidence of loss of response was 19% per patient-year with the second anti-TNF. Combination therapy (hazard ratio [HR], 2.4; 95% confidence interval [CI], 1.8–3; P < 0.0001) and ulcerative colitis vs Crohn’s disease (HR, 1.6; 95% CI, 1.1–2.1; P = 0.005) were associated with a higher probability of loss of response. Fifteen percent of the patients had adverse events, and 10% had to discontinue the second anti-TNF. Of the 71 patients who received a third anti-TNF, 55% achieved remission. The incidence of loss of response was 22% per patient-year with a third anti-TNF. Adverse events occurred in 7 patients (11%), but only 1 stopped the drug. Conclusions Approximately half of the patients who received a second anti-TNF achieved remission; nevertheless, a significant proportion of them subsequently lost response. Combination therapy and type of IBD were associated with loss of response. Remission was achieved in almost 50% of patients who received a third anti-TNF; nevertheless, a significant proportion of them subsequently lost response.
