Weekend endoscopic retrograde cholangiopancreatography has similar outcomes as weekday procedures-a propensity score match analysis of the Hungarian ERCP Registry.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is essential for the minimally invasive management of biliary and pancreatic disorders. Under certain indications, performing ERCP without delay during the weekend can be important for improving outcomes.

Objectives: To compare the outcomes of ERCP performed on weekends and holidays with those of regular weekday ERCPs.

Get reliable laboratory findings - how to recognize the deceptive effects of angiotensin-converting enzyme inhibitor therapy in the laboratory diagnostics of sarcoidosis?

Objectives: Serum angiotensin-converting enzyme (ACE) is the only biomarker routinely used in the laboratory diagnostics of sarcoidosis, and ACE inhibitor (ACEi) drugs are among the most prescribed drugs worldwide. Taking ACEi can mislead medical teams by lowering ACE activity, delaying diagnosis and giving a false impression of disease activity of sarcoidosis. We aimed to develop a simple method to detect the presence of ACEi drugs in samples, to investigate the ACEi medication-caused interference and consequences in a retrospective study.

Chitotriosidase gene polymorphisms and mutations limit the determination of chitotriosidase expression in sarcoidosis.

Serum chitotriosidase (CTO) activity was proposed as a biomarker in sarcoidosis being potentially useful in diagnostics. Nevertheless, a common duplication polymorphism (c.1049_1072dup24, Dup24) of the CTO gene influences CTO activity and thereby compromises its use in sarcoidosis.

[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.

Combined application of angiotensin converting enzyme and chitotriosidase analysis improves the laboratory diagnosis of sarcoidosis.

Establishing the diagnosis of sarcoidosis most often requires biopsy and histopathologic evaluation, since there is no single marker with sufficient specificity and sensitivity for the disease. Our aims were to determine and compare the diagnostic accuracies of several potential biomarkers and to develop a combined biomarker analysis tool for the diagnosis of sarcoidosis. 133 healthy individuals and 104 patients with suspected sarcoidosis and diagnostic thoracic surgery were enrolled into this study.

Deleterious effect of proton pump inhibitors on the disease course of cirrhosis.

Objectives: Proton pump inhibitors(PPIs) are widely prescribed to patients with liver cirrhosis. We hypothesized that long-standing PPI use is associated with spontaneous bacterial peritonitis(SBP) and accelerated development of disease-specific complications and liver-related death.

Methods: A 5-year follow-up observational cohort study assessed the impact of long-standing PPI use on the clinical course of cirrhosis in a large referral patient cohort.

Optimized angiotensin-converting enzyme activity assay for the accurate diagnosis of sarcoidosis.

Background: Serum angiotensin-converting enzyme (ACE) activity determination can aid the early diagnosis of sarcoidosis. We aimed to optimize a fluorescent kinetic assay for ACE activity by screening the confounding effects of endogenous ACE inhibitors and interfering factors. Genotype-dependent and genotype-independent reference values of ACE activity were established, and their diagnostic accuracies were validated in a clinical study.

norUrsodeoxycholic acid improves cholestasis in primary sclerosing cholangitis.

Background & Aim: Primary sclerosing cholangitis (PSC) represents a devastating bile duct disease, currently lacking effective medical therapy. 24-norursodeoxycholic acid (norUDCA) is a side chain-shortened C homologue of UDCA and has shown potent anti-cholestatic, anti-inflammatory and anti-fibrotic properties in a preclinical PSC mouse model. A randomized controlled trial, including 38 centers from 12 European countries, evaluated the safety and efficacy of three doses of oral norUDCA (500mg/d, 1,000mg/d or 1,500mg/d) compared with placebo in patients with PSC.

Rediscovery of the Anti-Pancreatic Antibodies and Evaluation of their Prognostic Value in a Prospective Clinical Cohort of Crohn's Patients: The Importance of Specific Target Antigens [GP2 and CUZD1].

Backgrounds: Glycoprotein 2[GP2] and CUB zona pellucida-like domain 1[CUZD1] belong to protein families involved in gut innate immunity processes and have recently been identified as specific targets of anti-pancreatic autoantibodies [PAbs] in Crohn's disease[CD]. We aimed to determine the prognostic potential of novel target-specific PAbs regarding long-term disease course of an adult CD patient cohort.

Methods: Sera of 458 consecutive well-characterised IBD patients from a single referral IBD centre were tested by enzyme-linked immunosorbent assay [ELISA] with isoform 4 of recombinant GP2 [anti-MZGP2 and anti-GP2 IgA/IgG] and indirect immunofluorescence test [IIFT] system with GP2 and CUZD1 expressing transfected HEK 293 cells [anti-rPAg2 and rPAg1 IgA/IgG].

A 1-year trial of repeated high-dose intravenous iron isomaltoside 1000 to maintain stable hemoglobin levels in inflammatory bowel disease.

Objective: Iron isomaltoside 1000 (Monofer®) is a high-dose intravenous (IV) iron, which in a recent 8 weeks trial in inflammatory bowel disease (IBD) subjects with iron deficiency anemia (IDA) demonstrated good tolerability and efficacy. The present trial is an extension to this trial, which evaluates the need for additional high IV iron doses to maintain a stable hemoglobin (Hb) ≥12.0 g/dl.

Once versus three times daily dosing of oral budesonide for active Crohn's disease: a double-blind, double-dummy, randomised trial.

Background: Oral budesonide 9 mg/day represents first-line treatment of mild-to-moderately active ileocolonic Crohn's disease. However, there is no precise recommendation for budesonide dosing due to lack of comparative data. A once-daily (OD) 9 mg dose may improve adherence and thereby efficacy.

Autologous dendritic cell based adoptive immunotherapy of patients with colorectal cancer-A phase I-II study.

Dendritic cell-based active immunotherapies of cancer patients are aimed to provoke the proliferation and differentiation of tumor-specific CD4(+) and CD8(+) T-lymphocytes towards protective effector cells. Isolation and in vitro differentiation of circulating blood monocytes has been established a reasonable platform for adoptively transferred DC-based immunotherapies. In the present study the safety and tolerability of vaccination by autologous tumor cell lysates (oncolysate)- or carcinoembriogenic antigen (CEA)-loaded DCs in patients with colorectal cancer was investigated in a phase I-II trial.

A randomized, open-label, non-inferiority study of intravenous iron isomaltoside 1,000 (Monofer) compared with oral iron for treatment of anemia in IBD (PROCEED).

Objectives: In the largest head-to-head comparison between an oral and an intravenous (IV) iron compound in patients with inflammatory bowel disease (IBD) so far, we strived to determine whether IV iron isomaltoside 1,000 is non-inferior to oral iron sulfate in the treatment of iron deficiency anemia (IDA).

Methods: This prospective, randomized, comparative, open-label, non-inferiority study was conducted at 36 sites in Europe and India. Patients with known intolerance to oral iron were excluded.

High prevalence of IgA class anti-neutrophil cytoplasmic antibodies (ANCA) is associated with increased risk of bacterial infection in patients with cirrhosis.

Background & Aims: Anti-neutrophil cytoplasmic antibodies (ANCA) are a non-uniform family of antibodies recognizing diverse components of neutrophil granulocytes. ANCA formation might be induced by protracted bacterial infections or probably reflect an abnormal immune response to commensal microorganisms. Bacterial infections are common complications in cirrhosis with high incidence of episodes caused by enteric organisms, therefore, we sought to study the presence and clinical importance of ANCA in cirrhosis.

Catheter-directed thrombolysis in inflammatory bowel diseases: report of a case.

In patients with inflammatory bowel diseases (IBD) the prevalence of thrombosis is 6.2%, the average incidence of thromboembolism (TE) is 3.6 times higher compared to normal population.

[Hungarian data on inflammatory bowel diseases: analytical data on ulcerative colistis].

Unlabelled: Prospective data collection seems to be essential in evidence-based medicine. Because of the new therapeutic options, the need for standard data collection and testing has significantly increased. In Hungary, a registry for patients with inflammatory bowel disease has already been set up, which makes it possible for clinicians to collect prospective data on their patients.

Budesonide 9 mg is at least as effective as mesalamine 4.5 g in patients with mildly to moderately active Crohn's disease.

Background & Aims: Comparative data on budesonide vs mesalamine for the treatment of mild-to-moderately active Crohn's disease (CD) are sparse. We assessed the efficacy and safety of each therapy in patients with mildly to moderately active CD.

Methods: We performed a randomized, double-blind, double-dummy, 8-week, multicenter study in which 309 patients with mildly to moderately active CD received pH-modified-release oral budesonide (9 mg/day once daily or 3 mg/day 3 times daily) or Eudragit-L-coated oral mesalamine (4.

NKX2-3 and IRGM variants are associated with disease susceptibility to IBD in Eastern European patients.

Aim: To investigate variants of immunity-related GTPase family M (IRGM) and NKX2-3 genes and genotype-phenotype in Eastern European patients with inflammatory bowel disease (IBD).

Methods: We analyzed 1707 Hungarian and Czech subjects with Crohn's disease (CD) (n = 810, age: 37.1 ± 12.

Presence of anti-microbial antibodies in liver cirrhosis--a tell-tale sign of compromised immunity?

Background: Bacterial translocation plays important role in the complications of liver cirrhosis. Antibody formation against various microbial antigens is common in Crohn's disease and considered to be caused by sustained exposure to gut microflora constituents. We hypothesized that anti-microbial antibodies are present in patients with liver cirrhosis and may be associated with the development of bacterial infections.

Serum lipopolysaccharide-binding protein and soluble CD14 are markers of disease activity in patients with Crohn's disease.

Background: In inflammatory bowel disease (IBD), enhanced inflammatory activity in the gut is thought to increase the risk of bacterial translocation and endotoxemia. In the present study we investigated the association between serum level of lipopolysaccharide-binding protein (LBP), soluble CD14 (sCD14), and clinical disease activity, high-sensitivity C-reactive protein (hs-CRP), antimicrobial serology profile, NOD2/CARD15 status, and clinical phenotype in a large cohort of Hungarian Crohn's disease (CD) patients.

Methods: In all, 214 well-characterized, unrelated, consecutive CD patients (male/female ratio: 95/119; age: 35.
