The incidence of Crohn disease (CD) has been increasing and surgery needs to be contemplated in a substantial number cases. relevant advent biological treatment changed but not eliminated the need for many patients. Despite previous publications on indications CD, there was comprehensive review existing evidence role elective options pediatric patients affected with CD. We present an expert opinion critical literature provide evidence-based guidance manage these Indications, surgical...

Inflammatory bowel disease–unclassified (IBD-U) is diagnosed in ∼10% of pediatric and adolescent onset IBD patients. The EUROKIDS registry (2004) initiated by the Porto working group ESPGHAN prospectively monitors diagnostic workup newly We aimed to describe workup, phenotype, change diagnosis over time IBD-U Data were collected on children from 52 centers across 20 European countries Israel, with May 2005 through November 2013. Full endoscopy plus small radiology was considered complete...

Most inflammatory bowel diseases (IBDs) are classic complex disorders represented by common alleles. Here we aimed to define the genetic architecture of pediatric and adult-onset IBDs for Polish population. A total 1495 patients were recruited, including 761 with Crohn's disease (CD; 424 pediatric), 734 ulcerative colitis (UC; 390 934 healthy controls. Allelotyping employed a pooled-DNA genome-wide association study (GWAS) was validated individual genotyping. Whole exome sequencing (WES)...

Abstract Primary biliary cholangitis (PBC), primary sclerosing (PSC), and inflammatory bowel diseases (IBDs), including Crohn’s disease (CD) ulcerative colitis (UC), are heterogeneous chronic autoimmune that may share underlying pathogenic mechanisms. Herein, we compared simultaneously analyzed blood transcriptomes from patients with PBC, PSC, IBD. Microarray-based measurements were conducted using RNA isolated whole samples 90, 45, 95 93 CD, UC, respectively, 47 healthy controls. Expression...

The aim of this study was to evaluate the influenza vaccination status among paediatric patients with inflammatory bowel disease (IBD) in Poland. This a questionnaire-based study. 242 IBD and 142 controls were enrolled Of IBD, 7.8% received an vaccine, compared 18.3% (P = 0.0013). There no statistically significant differences time from diagnosis, activity drugs, between vaccinated non-vaccinated children. In conclusion, data our demonstrate alarmingly poor majority children IBD. Therefore,...

<i>Background:</i> Prevention of <i>Helicobacter pylori</i> infection may help to control related gastritis, peptic ulcer and cancer. Of the possible preventive measures, immunization was successfully employed in various animal studies. However, no protocol has been accepted for humans. A better characterization immune response against pathogen be required before a human vaccine is developed. <i>Aim:</i> To identify bacterial proteins which induce an...
