Golimumab has demonstrated its long-term efficacy and safety in ulcerative colitis in clinical trials, but no data of long-term persistence has been published from real world. To estimate long-term persistence of golimumab, as well as factors associated with longer persistence, in patients with ulcerative colitis in real life. Observational multicentre study including adult patients with ulcerative colitis treated with golimumab and with at least twelve months of follow-up. We included 190 patients, 105 (55.26%) naive to anti-TNF, with mean disease duration of 9.32 ± 8.09 years. Probability of persistence was 63%, 46%, 39% and 27% at 1, 2, 3 and 4 years, respectively. Persistence was lower in patients with primary failure to previous anti-TNF. Eighty-two (43.16%) patients needed dose intensification during follow-up, with a mean time until intensification of 8.03 ± 8.64 months. Dose intensification and lower disease duration predicted higher persistence with golimumab (p = 0.037 and p = 0.008, respectively). During a follow-up of 17.25 ± 15.83 months, 32 (16.5%) patients needed hospitalisation and 11 (6%) underwent colectomy. No unexpected adverse events were reported. Golimumab has demonstrated good persistence and safety profile for long treatment in ulcerative colitis patients.

Summary Background Conflicting results have been recently reported for the accuracy of the Endoscopic Reference Score (EREFS), an standardised endoscopic classification, to predict the histological activity of eosinophilic oesophagitis (EoE). Aim To evaluate the accuracy of the EREFS to predict either histological or clinical activity of EoE. Methods Prospective multicentre study conducted in eight Spanish centres evaluating adult EoE patients, either naïve or after treatment. Symptoms were evaluated before upper endoscopy through the Dysphagia Symptom Score, whereas researchers scored the EREFS immediately after the endoscopic procedure, unaware of the histological outcome. Results One hundred and forty‐five EoE patients undergoing 240 consecutive endoscopic procedures were included. Exudates (P = 0.03), furrows (P = 0.03) and a composite score of inflammatory signs (exudates, furrows and oedema) (P < 0.001) accurately predicted histological activity. Exudates were the only endoscopic sign showing a good correlation with histological outcome after therapy. Furrows and oedema persisted in 50% and 70% of patients despite histological remission. No endoscopic feature exceeded 70% accuracy to predict histological activity. Likewise, no endoscopic finding could adequately predict dysphagia severity. Crepe paper mucosa, diffuse exudates and severe rings correlated with higher symptom scores. Conclusions Endoscopic findings assessed by the Endoscopic Reference Score did not correlate with histological or clinical disease activity in adult EoE patients. Only exudates correlated with peak eosinophil count and histological outcome, whereas furrows and oedema persisted in over half of patients despite histological remission.

Background Background: The feasibility of anti-TNF discontinuation in inflammatory bowel disease (IBD) must be proven in clinical trials including patients in clinical, endoscopic, and radiologic remission at the time of anti-TNF withdrawal to make recommendations for clinical practice. Aims Primary: to compare the rates of clinical remission at 1 year in patients who discontinue anti-TNF treatment vs. those who continue treatment. Secondary objectives: to know the effect of anti-TNF withdrawal on relapse-free time, mucosal healing and safety; and to identify predictive factors for relapse. Methods Prospective, quadruple-blind, multicentre, randomised, controlled trial. Patients with ulcerative colitis (UC) or Crohn’s disease (CD) in clinical remission for &gt; 6 months were randomised to maintain anti-TNF treatment [maintenance arm (MA)] or to withdraw it [withdrawal arm (WA)]. Patients who were on infliximab (IFX) received IFX 5 mg/kg or an intravenous placebo every 8 weeks, while patients on adalimumab (ADA) received subcutaneous ADA 40 mg or placebo every other week. Patients were followed-up until month 12 or up to the time of clinical relapse, whichever came first. Inclusion and exclusion criteria, trial scheme and definitions are summarized in figures 1a, 1b and 1c. Results were analysed by intention-to-treat (ITT) and by per-protocol (PP). Local investigators were blinded to faecal calprotectin (FC) and IFX and ADA trough levels. On-site monitoring was performed to assess data quality. Results 159 patients were screened, from whom 140 were randomised and comprised the ITT cohort: 70 allocated to the MA and 70 to the WA. Fifteen patients dropped out before the end of follow-up (12 months or relapse), leaving 63 patients in the MA and 62 patients in the WA for the PP analysis. The characteristics of patients in the MA and WA were similar (figure 2). The proportions of patients who maintained clinical remission -59/70 (84%), 95% confidence interval (CI)=74-92% in the MA vs. 53/70 (76%), 95%CI=64-85% in the WA- and who remained without significant endoscopic lesions at the end of follow-up were similar between groups (figures 3a, 3b, 3c). Only the proportion of patients with FC &gt;250 mg/g was higher in the WA at the end of follow-up (figure 3d). Maintenance of clinical remission was no different between groups (figure 4). The same percentage of patients in both groups had at least one adverse event (69%). The proportion of patients with serious adverse events was also similar between groups (4% in MA vs. 7% in WA). Conclusion Anti-TNF withdrawal in selected IBD patients in clinical, endoscopic, and radiologic remission could be feasible without an increase in the risk of clinical relapse. Long-term follow-up of these patients is warranted.
