Background: Proton pump inhibitors (PPIs) are the most commonly used first-line therapy for patients with eosinophilic oesophagitis (EoE). However, many aspects related to PPIs in EoE are still unknown. Aims:To assess the effectiveness of PPI therapy for EoE in real-world practice. Methods:This cross-sectional study collected data on PPI efficacy from the multicentre EoE CONNECT database. Clinical remission was defined as a decrease of ≥50% in dysphagia symptom score; histological remission was defined as a peak eosinophil count below 15 eosinophils per high-power field. Factors associated with effectiveness of PPI therapy were identified by binary logistic regression multivariate analyses.Results: Overall, 630 patients (76 children) received PPI as initial therapy (n = 600) or after failure to respond to other therapies (n = 30). PPI therapy achieved eosinophil density below 15 eosinophils per high-power field in 48.8% and a decreased symptom score in 71.0% of patients. More EoE patients with an inflammatory rather than stricturing phenotype accomplished clinico-histological remission after PPI therapy (OR 3.7; 95% CI, 1.4-9.5); as well as those who prolonged treatment length from 8 to 12 weeks (OR 2.7; 95% CI, 1.3-5.3). After achieving clinico-histological remission of EoE, PPI dosage reduction was effectively maintained in 69.9% of patients, but tended to be less effective among those with a stricturing phenotype.Conclusions: Inflammatory EoE phenotype and treatment duration up to 12 weeks correlated with greater chance for inducing remission of EoE. A stricturing phenotype decreased response rates to PPI therapy both initially and in the long term.

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 Empiric triple therapy for Helicobacter pylori should be abandoned when clarithromycin resistance rate is >15–20%. Optimisation of triple therapy (high‐dose acid suppression and 14‐day duration) can increase eradication rates by 10%. Aim To compare the efficacy and safety of optimised triple (OPT‐TRI) and nonbismuth quadruple concomitant (OPT‐CON) therapies. Methods Prospective multicentre study in 16 Spanish centres using triple therapy in clinical practice. In a 3‐month two‐phase fashion, the first 402 patients received an OPT‐TRI therapy [esomeprazole (40 mg b.d.), amoxicillin (1 g b.d) and clarithromycin (500 mg b.d) for 14 days] and the last 375 patients an OPT‐CON treatment [OPT‐TRI therapy plus metronidazole (500 mg b.d)]. Results Seven‐hundred seventy‐seven consecutive patients were included (402 OPT‐TRI, 375 OPT‐CON). The OPT‐CON therapy achieved significantly higher eradication rates in the per‐protocol [82.3% (95% CI = 78–86%) vs. 93.8% (91–96%), P < 0.001] and intention‐to‐treat analysis [81.3% (78–86%) vs. 90.4% (87–93%), P < 0.001]. Adverse events (97% mild/moderate) were significantly more common with OPT‐CON therapy (39% vs. 47%, P = 0.016), but full compliance with therapy was similar between groups (94% vs. 92%, P = 0.4). OPT‐CON therapy was the only significant predictor of successful eradication (odds ratio, 2.24; 95% CI: 1.48–3.51, P < 0.001). The rate of participating centres achieving cure rates ≥90% favoured OPT‐CON therapy (OPT‐TRI 25% vs. OPT‐CON 62%). Conclusions Empiric OPT‐CON therapy achieved significantly higher cure rates (>90%) compared to OPT‐TRI therapy. Addition of metronidazole to OPT‐TRI therapy increased eradication rates by 10%, resulting in more mild adverse effects, but without impairing compliance with therapy.
