Evidence on serological responses to vaccination in children exposed to ustekinumab (UST) or vedolizumab (VDZ) in utero is lacking. This multicentre prospective study aimed to assess the impact of prenatal exposure to UST or VDZ due to maternal inflammatory bowel disease (IBD) on serological responses to vaccination and other immunological parameters in exposed children. Children aged ≥ 1 year who were exposed in utero to UST or VDZ and completed at least 1-year of mandatory vaccination were included. We assessed the serological response to vaccination (non-live: tetanus, diphtheria, and Haemophilus influenzae B; live: mumps, rubella, and measles), whole blood count, and immunoglobulin levels. The control group comprised unexposed children born to mothers without IBD. A total of 23 children (median age, 25 months) exposed to UST (n = 13) or VDZ (n = 10) and 10 controls (median age, 37 months) were included. The serological response to vaccination was comparable between the UST and VDZ groups and controls, with an adequate serological response rate of ≥ 80%. Only children exposed to UST showed a slightly reduced serological response to mumps (67% vs. 86% in controls), whereas all children exposed to VDZ showed an adequate response. The majority of the exposed children had normal levels of individual immunoglobulin classes, similar to the controls. No severe pathology was observed in any of the children.Conclusion: Despite the limited sample size, our findings suggest that in utero exposure to VDZ or UST does not significantly impair the vaccine response or broader immunological parameters in exposed children.

BACKGROUND/AIMS: Originator-adalimumab, an established treatment for patients with Crohn's disease (CD), showed no difference in efficacy or adverse events versus adalimumab biosimilar SB5 (SB5-adalimumab) over 10 weeks (W) of treatment. To understand the long-term effectiveness of SB5-adalimumab in CD, patients switched from originator-adalimumab to SB5-adalimumab were compared with patients remaining on originator-adalimumab over 104 W. METHODS: Data on patients aged ≥18 years, diagnosed with CD and treated at ISCARE, were collected prospectively from July 2018 to January 2021. Primary outcome: clinical disease activity at W52, measured by Harvey-Bradshaw index (HBI). Secondary outcomes: C-reactive protein (CRP), faecal calprotectin (FC) and adalimumab concentrations at W10, 26, 52 and 104, and treatment persistence. To ensure comparable cohorts, patients were propensity score (PS)-matched for age, gender and disease activity. RESULTS: After matching, 54 patients remained per cohort. At W52, mean (SD) HBI score was 3.2 (2.5) for originator-adalimumab and 4.0 [3.6] for SB5-adalimumab (difference [95% CI] -0.78 [-2.8, 1.3]; n = 18/cohort); no clinically meaningful differences in CRP, FC or drug concentrations were noted. Kaplan-Meier's estimates (95% CI) of remaining on treatment were originator-adalimumab: 0.870 (0.785-0.965) versus SB5-adalimumab: 0.648 (0.533-0.789) at W52 and significantly lower for SB5-adalimumab versus originator-adalimumab (p < .001) over 104 W. Local skin reaction events/pain was the main reason for treatment discontinuation in the SB5-adalimumab cohort (n = 20/54 [37%]). CONCLUSIONS: These long-term results of CD patients receiving originator-adalimumab or following nonmedical switch to SB5-adalimumab show similar therapeutic effects on clinical disease activity, biological parameters and pharmacokinetic profile in both cohorts from 52 to 104 W. A separation in persistence was observed beyond W26, mainly due to differences in local reactions at the injection site.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic poses a challenge to healthcare. Staff and patients are at increased risk during an examination or intervention, so certain restrictions ought to be introduced. Hence, we aimed to measure the effect of the pandemic on endoscopy units in real-life settings. Methods: This was an observational, cross-sectional, questionnaire-based study, carried out between 7 April and 15 June 2020. Responds came from many countries, and the participation was voluntary. The survey contained 40 questions, which evaluated the effect of the COVID-19 pandemic on the endoscopy units and assessed the infection control. Results: A total of 312 questionnaires were filled, 120 from Hungary, and 192 internationally, and 54 questionnaires (17.3%) were sent from high-risk countries; 84.9% of the gastroenterologists declared that they read the European Society of Gastrointestinal Endoscopy (ESGE) statement, while only 32.1% participated in any advanced training at their workplace. Overall, 92.1% of gastroenterologists realized risk stratification, and 72.1% claimed to have enough protective equipment. In 52.6% of the endoscopy units, at least one endoscopist had to discontinue the work due to any risk factor, while 40.6% reported that the reduced staff did not affect the workflow. Gastroenterologists considered that the five most important examinations both in low and high-risk patients are the following: lower/upper gastrointestinal (GI) bleeding with hemodynamic instability, endoscopic retrograde cholangiopancreatography (ERCP) in obstructive jaundice, foreign body in the esophagus, ERCP in acute biliary pancreatitis, and iron deficiency anemia with hemodynamic instability, which correlates well with the ESGE recommendation. Significant correlation was found in the usage of the necessary protective equipment in high-risk patients depending on the countries (p < 0.001). Conclusions: The survey found weak correlation in preliminary training depending on countries; nevertheless, in Hungary during the examined period, endoscopists considered the recommendations more strictly than in other countries. Although many physicians left the endoscopy lab, the workflow was not affected, probably due to the reduced number of examinations.

Úvod: Tofacitinib je léčivo ze skupiny inhibitorů Janusovy kinázy v perorální formě, které je určeno pro léčbu ulcerózní kolitidy (UC – ulcerative colitis). Účinnost přípravku byla prokázána v registračních studiích, avšak data o účinnosti a bezpečnosti z klinické praxe jsou dosud zřídkavá. Cílem této práce bylo posoudit klinickou odpověď na 8týdenní indukční léčbu tofacitinibem u pacientů s UC. Metodika: Do hodnocení byli zařazeni konsekutivní pacienti, u kterých byla zahájena léčba tofacitinibem v dávce 2 × 10 mg denně. Aktivita onemocnění byla posuzována indexem aktivity Mayo vč. endoskopického subskóre na počátku léčby a v týdnu 8, spolu s hodnocením zánětlivých parametrů v podobě C-reaktivního proteinu (CRP) a fekálního kalprotektinu (FC – fecal calprotectin). Jako odpovídající na léčbu byli v týdnu 8 hodnoceni pacienti s celkovým indexem Mayo 0–5 spolu s endoskopickým subskóre 0–1. Při každé návštěvě byly hodnoceny nežádoucí účinky léčby. Výsledky: Hodnocení proběhlo u 24 pacientů (41,7 % muži, 58,3 % ženy) o průměrném stáří 35,3 ± 11,8 let. Průměrná doba trvání choroby byla 8,3 ± 5,2 let. Průměrný pacient souboru byl v minulosti léčen dvěma biologiky, nicméně 25 % bylo zcela naivních k biologické léčbě. V týdnu 0 byla souběžná léčba kortikoidy přítomna u 41,7 % pacientů, jiná imunosupresvní nebo biologická léčba podávána nebyla. Po 8 týdnech odpovědělo na léčbu 52,9 % pacientů. Celkové Mayo skóre pokleslo u respondérů z hodnoty 5,9 ± 3,5 na 1,1 ± 1,3 (p = 0,01), zatímco u nonrespondérů došlo k nesignifikantní změně z 8,0 ± 2,5 na 8,9 ± 2,1 (p = 0,86). Zlepšení endoskopického skóre z 2,0 ± 1,0 na 0,6 ± 0,7 (p = 0,02) u respondérů kontrastuje se zcela nezměněnou hodnotou u pacientů bez odpovědi (2,9). Významný pokles hodnot CRP (6,7 ± 6,2 vs. 2,0 ± 2,2 mg/l; p = 0,04 a FC (1 195 ± 1 189 vs. 578 ± 654 μg/g; p = 0,05) byl zaznamenán rovněž pouze v kohortě s klinickou odpovědí. Všechny hodnocené parametry v týdnu 0 byly v obou kohortách srovnatelné, s výjimkou triacylglycerolů, jejichž vstupní hodnota byla u nonrespondérů vyšší. Léčba byla do 8 týdnů ukončena u 23,5 % pacientů, u všech z důvodu nedostatečné odpovědi. Byly zaznamenány dvě stížnosti na bolesti hlavy po zahájení léčby a po jednom výskytu cytomegalovirové kolitidy, klostridiové kolitidy a orální kandidózy. Závěr: Účinnost indukční fáze léčby tofacitinibem byla pozorována přibližně u poloviny pacientů s UC. S ohledem na omezený vzorek pacientů a délku terapie nutno získat dlouhodobá data o účinnosti a bezpečnosti léku.

Introduction: Tofacitinib is an oral Janus kinase inhibitor approved for the treatment of ulcerative colitis (UC). Its efficiency was proven in registration trials, however data from real clinical practice are still sparse. Our aim was to evaluate efficacy and safety of tofacitinib in UC patients within 8-week induction period. Methods: Data from consecutive UC patients who started tofacitinib 10 mg twice a day were evaluated. Disease activity was assessed by Mayo score including endoscopic Mayo at baseline and week 8 together with C-reactive protein (CRP) and fecal calprotectin (FC). At week 8, patients with total Mayo ≤ 5 with endoscopic subscore ≤ 1 were considered responders. Adverse events were registered at each visit. Results: A total of 24 patients (41.7% males), mean age 35.3 ±11.8 years were included. The mean disease duration was 8.3 ± 5.2 years. In median, the patients were previously treated with two biologic agents, however 25% of the patients were naïve to any biologic therapy. Systemic corticosteroids were present in 41.7% of patients at baseline and no patient had concomitant biologic or immunosuppressive therapy. At week 8, 52.9% of patients responded to treatment. The mean total Mayo decreased in responders from 5.9 ± 3.5 to 1.1 ± 1.3 (p = 0.01), while non-responders it changed from 8.0 ± 2.5 to 8.9 ± 2.1 (p = 0.86). Endoscopic subscore decreased from 2.0 ± 1.0 to 0.6 ± 0.7 (p = 0.02) in responders, however remained stable in non-responders (2.9). CRP and FC dropped significantly in responders (6.7 ± 6.2 vs. 2.0 ± 2.2 mg/L, p = 0.04; 1,195 ± 1,189 vs. 578 ± 654 μg/g, p = 0.05), but not in non-responders. Non-responders had significantly higher baseline triglycerides compared to responders. Tofacitinib was stopped in 23.5% of patients until week 8 due to insufficient response. Two patients reported headaches after treatment initiation and single events of Cytomegalovirus colitis, Clostridium difficile colitis and oral candidiasis occurred. Conclusion: Tofacitinib was efficient in inducing clinical response with mucosal healing in about half of UC patients after 8 weeks of therapy. A need for long-term outcomes and for safety data with emphasis on infectious complications warrant further investigation.

BACKGROUND: Discontinuation of anti-TNF therapy in patients with inflammatory bowel diseases (IBD) in remission remains a controversial issue. The aims of our study were to assess the proportion of patients who relapse after cessation of biological treatment, and to identify potential risk factors of disease relapse. METHODS: Consecutive IBD patients who discontinued anti-TNF therapy in steroid-free clinical and endoscopic remission were prospectively followed. Multiple logistic regression and Cox proportional-hazards models were used to assess the predictors of disease relapse. RESULTS: Seventy-eight IBD patients (Crohn's disease, CD 61; ulcerative colitis, UC 17) were included and followed for a median of 30 months (range 7-47). A total of 32 (53%) CD patients and nine (53%) UC patients relapsed by the end of the follow-up with a median time to relapse of 8 months (range 1-25) in CD patients and 14 months (range 4-37) in UC patients, respectively. The cumulative probabilities of maintaining remission at 6, 12, and 24 months were 82%, 59%, and 51% in CD patients, and 77%, 77%, and 64% in UC patients, respectively. Survival of CD patients who were in deep remission (clinical and endoscopic healing; faecal calprotectin <150 mg/kg; CRP ≤5 mg/l) was not better compared with those who did not fulfill these criteria. In multivariate models, only colonic CD protected patients from disease relapse. CONCLUSIONS: Approximately half of the IBD patients relapsed within 2 years after anti-TNF discontinuation. In CD patients, no difference between those who were or were not in deep remission was found. Colonic localization protected patients from relapse.

INTRODUCTION: CT-P13 is the first biosimilar to infliximab that has been approved for the same indications as its originator infliximab. No data are available on the effect of infliximab biosimilar on mucosal healing. The aim of this study was to evaluate the efficacy of CT-P13 induction therapy on mucosal healing in patients with ulcerative colitis [UC]. PATIENTS AND METHODS: UC patients, who received CT-P13 therapy from its local introduction at three Hungarian and one Czech inflammatory bowel disease centres, were prospectively enrolled. Sigmoidoscopy was performed after the end of the induction therapy at week 14. Mucosal healing was defined as Mayo endoscopic subscore 0 or 1. Complete mucosal healing was defined as Mayo endoscopic subscore 0. Trough level of CT-P13 was measured at week 14. RESULTS: Sixty-three UC patients who underwent CT-P13 induction therapy were enrolled in the study. Indication for the therapy was acute, severe flare up and chronic, refractory activity in 24 and 39 patients, respectively. Cumulative clinical response and steroid-free remission at week 14 were achieved in 82.5% and 47.6% of the patients, respectively. Sigmoidoscopy revealed steroid-free mucosal healing in 47.6% of the patients, and complete mucosal healing was present in 27%. Mayo endoscopic subscore decreased significantly at week 14 compared to baseline. Trough levels of infliximab correlated with mucosal healing. CONCLUSION: This is, to our knowledge, the first study examining the efficacy of CT-P13 induction therapy on mucosal healing in UC. The results indicate that mucosal healing is achieved in two-thirds of UC patients by the end of the induction treatment with CT-P13.
