The aim was to investigate the effect of proton pump inhibitors on remission rates in patients with inflammatory bowel disease treated with the gut-selective vedolizumab. Patients from the Hungarian nationwide, multicenter vedolizumab cohort were selected for post hoc analysis.

Real-Life Efficacy of Tofacitinib in Various Situations in Ulcerative Colitis: A Retrospective Worldwide Multicenter Collaborative Study.

Background And Aims: Tofacitinib (TFB) appears to be effective in the treatment of ulcerative colitis (UC); however, available real-world studies are limited by cohort size. TFB could be an option in the treatment of acute severe ulcerative colitis (ASUC). We aimed to investigate efficacy and safety of TFB in moderate-to-severe colitis and ASUC.

Ustekinumab is associated with superior treatment persistence but not with higher remission rates vedolizumab in patients with refractory Crohn's disease: results from a multicentre cohort study.

Background: Treatment with antitumor necrosis factor alpha (anti-TNF-α) is safe and effective as first-line therapy; however, its efficacy is limited due to primary nonresponse (PNR) and secondary loss of response (LOR), resulting in treatment discontinuation in approximately 40%-50% of cases. Vedolizumab (VDZ) and ustekinumab (UST) therapies could be good alternatives in patient with anti-TNF failure; however, no head-to-head randomized comparison of these drugs as second- or third-line treatments has been made.

Objectives: This study aimed to assess the treatment persistence and comparative effectiveness of UST and VDZ in patients with refractory Crohn's disease (CD).

Background: The TRANS-IBD study examines the superiority of joint transition visits, with drug adherence and patient satisfaction among the outcome measures. Our aim was a cross-cultural, age- and disease-specific adaptation of the 'Medication Adherence Rating Scale' (MARS) and 'Patient satisfaction with health care in inflammatory bowel disease questionnaire' (CACHE) questionnaires in patients with inflammatory bowel disease (IBD).

Methods: Linguistic and cultural adaptation using test and re-test procedures were performed.

Intravenous versus subcutaneous delivery of biotherapeutics in IBD: an expert's and patient's perspective.

Several biologic treatments are available in addition to intravenous also in subcutaneous form for treatment of chronic diseases. Benefits of the subcutaneous application of drugs include self-administration by the patient, shorter time of application process with less infusion related adverse events and consequently lower healthcare costs. With appropriate education and support patients are able to administer their treatments at home.

Characteristics of adult patients with chronic intestinal failure due to short bowel syndrome: An international multicenter survey.

Background And Aims: The case-mix of patients with intestinal failure due to short bowel syndrome (SBS-IF) can differ among centres and may also be affected by the timeframe of data collection. Therefore, the ESPEN international multicenter cross-sectional survey was analyzed to compare the characteristics of SBS-IF cohorts collected within the same timeframe in different countries.

Methods: The study included 1880 adult SBS-IF patients collected in 2015 by 65 centres from 22 countries.

Introduction: Although efficacy of ustekinumab (UST) has been demonstrated through randomized trials, data from real-life prospective cohorts are still limited. Our aim was to evaluate clinical efficacy, drug sustainability, dose intensification and results from therapeutic drug monitoring in UST treated patients with Crohn's disease (CD) using a prospective, nationwide, multicenter cohort.

Methods: Patients from 10 Inflammatory Bowel Disease centers were enrolled between 2019 January and 2020 May.

[Management of acute gastrointestinal bleeding. Multidisciplinary guideline proposal].

Gastrointestinal bleeding has a profound impact on public health due to its high prevalence and severity. With the elderly population taking more anticoagulants/antiaggregants/non-steroid anti-inflammatory drugs, the digestive bleeding will certainly raise more and more challenges in quantity as well as in severity for the public healthcare system. The emergency medicine specialists and gastroenterologists have a central role in the management of patients presenting with gastrointestinal bleeding.

Real-life efficacy of vedolizumab on endoscopic healing in inflammatory bowel disease - A nationwide Hungarian cohort study.

: GEMINI trials demonstrated the therapeutic efficacy of vedolizumab (VDZ) in Crohn's disease (CD) and ulcerative colitis (UC).: Aim of this study was to determine the real-life effectiveness of VDZ on endoscopic healing in the Hungarian nationwide cohort of inflammatory bowel disease (IBD) patients based on the changes on clinical and endoscopic scores. Every adult IBD patient in the country (121 UC and 83 CD) who completed the short-term VDZ therapy was enrolled, of which 72 UC and 52 CD patients could complete the long-term therapy.

Patient and general population values for luminal and perianal fistulising Crohn's disease health states.

Background: In patients with Crohn's disease (CD), luminal disease activity paralleled by perianal fistulas may seriously impair health-related quality of life (HRQoL). Health utility values are not available from patients with CD that reflect the health loss associated with both luminal and perianal CD.

Objective: To generate utilities for luminal and concomitant perianal fistulising CD health states directly from patients and from members of the general public.

Home parenteral nutrition provision modalities for chronic intestinal failure in adult patients: An international survey.

Background & Aims: The safety and effectiveness of a home parenteral nutrition (HPN) program depends both on the expertise and the management approach of the HPN center. We aimed to evaluate both the approaches of different international HPN-centers in their provision of HPN and the types of intravenous supplementation (IVS)-admixtures prescribed to patients with chronic intestinal failure (CIF).

Methods: In March 2015, 65 centers from 22 countries enrolled 3239 patients (benign disease 90.

Outcomes of Patients With Inflammatory Bowel Diseases Switched From Maintenance Therapy With a Biosimilar to Remicade.

Background & Aims: There is evidence that it is safe and effective for patients with inflammatory bowel diseases (IBD) to switch from maintenance therapy with an original infliximab drug to a biosimilar, but little is known about outcomes of reverse switches and/or multiple switches. We aimed to evaluate the effects of a reverse switch (from a biosimilar to Remicade) in a real-life cohort.

Methods: We performed a prospective observational study of 174 unselected and consecutive patients with IBD (136 with Crohn's disease [CD] and 38 with ulcerative colitis [UC]) who received maintenance therapy with the biosimilar in Hungary.

Presence and Effects of Pituitary Adenylate Cyclase Activating Polypeptide Under Physiological and Pathological Conditions in the Stomach.

Pituitary adenylate cyclase activating polypeptide (PACAP) is a multifunctional neuropeptide with widespread occurrence throughout the body including the gastrointestinal system. In the small and large intestine, effects of PACAP on cell proliferation, secretion, motility, gut immunology and blood flow, as well as its importance in bowel inflammatory reactions and cancer development have been shown and reviewed earlier. However, no current review is available on the actions of PACAP in the stomach in spite of numerous data published on the gastric presence and actions of the peptide.

Clinical classification of adult patients with chronic intestinal failure due to benign disease: An international multicenter cross-sectional survey.

Background & Aims: The aim of the study was to evaluate the applicability of the ESPEN 16-category clinical classification of chronic intestinal failure, based on patients' intravenous supplementation (IVS) requirements for energy and fluids, and to evaluate factors associated with those requirements.

Methods: ESPEN members were invited to participate through ESPEN Council representatives. Participating centers enrolled adult patients requiring home parenteral nutrition for chronic intestinal failure on March 1st 2015.

[Introduction of a quality index in a Hungarian endoscopy unit].

Unlabelled: The quality of endoscopic examinations substantially determines their value. In developed countries, Continuous Quality Management is used to improve it permanently. In Hungary there is no example for measuring quality in the field of gastrointestinal endoscopy.

Functional evaluation of multidrug resistance transporter activity in surgical samples of solid tumors.

Determination of multidrug resistance (MDR) activity of tumor cells could provide important information for the personalized therapy of cancer patients. The functional calcein assay (MultiDrug Quant Assay, Solvo Biotechnology, Budaörs, Hungary) has been proven to be clinically valuable in hematological malignancies by determining the transporter activity of MDR protein 1 (MDR1, ATP-binding cassette protein [ABC] B1, P-glycoprotein-170) and MDR-related protein 1 (MRP1, ABCC1). In this study, we evaluated if the same functional test was adaptable for the analysis of MDR activity in solid tumors.

Early diagnosis of pancreatobiliary duct malignancies by brush cytology and biopsy.

Two hundred and five preoperative intraductal samplings (brushing and biopsy) were evaluated from 113 patients with biliary or Wirsung duct strictures. One hundred and three strictures could be specified by histology of the operative specimens, autopsy, or by the patients' clinical course. Preoperative diagnostic efficacy depended on the tumor location (it was the best for ampullary and para-papillary tumors), but the average quantitative indices for sensitivity, absolute sensitivity, specificity, positive and negative predictive values, diagnostic accuracy of cytology were 53%, 20%, 100%, 100%, 25%, 59%, respectively.

Comparison of ELISA-based tyrosine kinase assays for screening EGFR inhibitors.

Receptor tyrosine kinases (PTKs) play key roles in the pathogenesis of numerous human diseases, including cancer, and therefore PTK inhibitors are currently under intense investigation as potential drug candidates. PTK inhibitor screening data are, however, poorly comparable because of the different assay technologies used. Here we report a comparison of ELISA-based assays for screening epidermal growth factor receptor (EGFR) tyrosine kinase (TK) inhibitory compound libraries to study interassay variations.
