BACKGROUND There are only a few studies on immune response to routine vaccinations in children with inflammatory bowel disease (IBD), despite a strong need for this kind of study. The aim of the study was to evaluate the immunogenicity of an inactivated hepatitis A vaccine (HAV) in IBD pediatric patients compared with healthy controls. METHODS This was an(More)
BACKGROUND 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 IBD working group of ESPGHAN prospectively monitors diagnostic workup of newly diagnosed pediatric and adolescent onset IBD patients. We aimed to describe diagnostic workup,(More)
BACKGROUND/AIMS The incidence of pediatric inflammatory bowel disease (IBD) in Western countries is on the rise. No prospective studies have been conducted on the epidemiology of pediatric IBD in Poland. The aim of the study was to define the characteristics of new pediatric IBD and assess the incidence of new IBD among children in Poland between 2002 and(More)
BACKGROUND There are only a few studies on immune response to pneumococcal vaccines in patients with inflammatory bowel disease (IBD); all of them assessed polysaccharide vaccines only. The aim of the study was to evaluate the immunogenicity and safety of 13-valent pneumococcal conjugate vaccine (PCV13) in IBD pediatric patients compared with healthy(More)
BACKGROUND The aim of this study was to confirm the role of antral nodularity in the diagnosis of Helicobacter pylori (H. pylori) infection in children. MATERIAL AND METHODS This prospective study included 107 children (58 male; 54.2%), between the ages of 3 and 18 years, infected with H. pylori, which was confirmed if the patient had at least 2 of 4(More)
INTRODUCTION No study to date has evaluated perinuclear antineutrophil cytoplasmic antibody (pANCA) and anti-Saccharomyces cerevisiae antibody (ASCA) in pediatric inflammatory bowel disease-unclassified (IBDU) as compared with Crohn's colitis (CC) and ulcerative colitis (UC), which represent the diagnostic challenge. We aimed to explore the diagnostic(More)
Gastroesophageal reflux disease is common in adult patients with interstitial lung disease. However, no data currently exist regarding the prevalence and characteristics of the disease in pediatric patients with interstitial lung disease. The aim of the present study was to prospectively assess the incidence of gastroesophageal reflux disease and(More)
BACKGROUND There are limited data on antibody response to vaccination in patients with inflammatory bowel disease (IBD). In this study, we aimed to assess the immunogenicity of a booster dose of pertussis vaccine in pediatric patients with IBD and to compare their response with healthy controls. METHODS We performed a multicenter, prospective, and(More)
The incidence of Crohn disease (CD) has been increasing and surgery needs to be contemplated in a substantial number of cases. The relevant advent of biological treatment has changed but not eliminated the need for surgery in many patients. Despite previous publications on the indications for surgery in CD, there was a need for a comprehensive review of(More)
