Excessive laxity of the connective tissue refers to a group of inherited abnormalities manifested by disturbances in the functioning of internal organs, including the gastrointestinal tract. Increased susceptibility to stretching of the distal part of the large intestine and abnormal colonic motor function could explain the predisposition to the development of functional constipation in some children. Our aim was to determine whether patients with functional constipation are more likely to be characterized by congenital laxity of connective tissue compared to the population of healthy children.

Introduction: In most European countries, an infliximab biosimilar (CT-P13) is currently in common use. In vitro and in vivo studies have proved a high similarity between CT-P13 and the reference infliximab. CT-P13 was licensed for use in patients with Crohn disease (CD) based on the extrapolation of data from preclinical studies and clinical trials in rheumatology indications.

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 controlled trial.

The aim of this study was to evaluate the serotype-specific pneumococcal status of children and adolescents with inflammatory bowel disease (IBD) who were naïve to pneumococcal vaccination before administering the 13-valent pneumococcal conjugate vaccine (PCV 13). This was an open, prospective study on children and adolescents aged 5-18 years who had IBD and were naïve to pneumococcal vaccination. A single dose of PCV 13 was administered to each patient.

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 controls.

Methods: This was a multicenter, prospective, and controlled study on children and adolescents aged 5 to 18 years with IBD with no history of pneumococcal immunization.

Background And Aims: Clostridium difficile is the major cause of antibiotic-associated diarrhea and is the most well known bacterial pathogen associated with inflammatory bowel disease (IBD). Enterotoxigenic Clostridium perfringens has also been detected in up to 15% of antibiotic-associated diarrhea cases, and it has not been found in healthy people. The aim of this study was to investigate the prevalence of C.

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 open, prospective, and controlled study on anti-HAV-negative children and adolescents age 2-18 years with IBD.
