Impaired immune regulation has been suggested as an underlying mechanism of inflammatory bowel disease. Indoleamine 2,3-dioxygenase (IDO) and regulatory T cells expressing FOXP3 are crucial elements of immune regulation. Conversion of FOXP3- lymphocytes to Tregs is one of the functions of IDO. The aim of this study was to evaluate the number of cells expressing FOXP3 and IDO in the lamina propria of intestinal mucosa and to evaluate correlations between these parameters and disease activity. Sixty-six children newly diagnosed with inflammatory bowel disease (41 patients with ulcerative colitis and 25 patients with Crohn’s disease) were included in the study...

OBJECTIVES: Patients with inflammatory bowel disease (IBD) often receive immunosuppressive therapy which may make them vulnerable to infections such as hepatitis B. We hypothesized that hepatitis B virus (HBV) titers are low in the vaccinated pediatric IBD population. The aims of our study were to identify the incidence of lower titers of hepatitis B surface antibody (HBsAb) and determine which patient factors may be associated with lower HBsAb titers. METHODS: Patients with diagnosis of IBD, ages 5-18 years, were prospectively enrolled...

BACKGROUND: Data on ocular manifestations of inflammatory bowel disease (IBD) in children are limited. Some authors have reported a high prevalence of asymptomatic uveitis, yet the significance of these observations is unknown and there are no recommendations on which ophthalmologic follow-up should be offered. METHODS: Children with IBD seen at a single referral center for pediatric gastroenterology were offered ophthalmologic evaluation as part of routine care for their disease...

Zoe, a 13-year-old white girl, presents as a new patient to your pediatric clinic with complaints of frequent emesis, anxiety, and learning problems, and previous diagnosis of cerebellar ataxia. Parents accompany Zoe and state, "it is really hard for her to go out, she gets sick and falls easily." She was born full term by vaginal delivery without complications. Given globally delayed milestones, she received early intervention services. Feeding problems began at infancy, including gastroesophageal reflux and aspiration pneumonia...

Objectives. Ulcerative colitis (UC) and Crohn's disease (CD) are chronic inflammatory bowel diseases (IBD) with unclear underlying aetiologies. Severe cardiac arrhythmias have been emphasised in a few studies on adult IBD patients. This study aimed to investigate the alteration of the P-wave and QT interval dispersion parameters to assess the risk of atrial conduction and ventricular repolarisation abnormalities in pediatric IBD patients. Patients and Methods. Thirty-six IBD patients in remission (UC: 20, CD: 16) aged 3-18 years and 36 age- and sex-matched control patients were enrolled in the study...

BACKGROUND: Proteolytic cleavage of protease-activated receptor 1 (PAR1) can result in potent downstream regulatory effects on inflammation. Although PAR1 is expressed throughout the gastrointestinal tract and activating proteases are increased in inflammatory bowel disease, the effect of PAR1 activation on colitis remains poorly understood, and has not previously been studied in pediatric disease. METHODS: Expression of PAR1 and inflammatory cytokines in colonic biopsies from pediatric patients with Crohn's disease exhibiting active moderate to severe colitis was measured by quantitative PCR...

INTRODUCTION: Inflammatory bowel disease is a chronic condition of the gastrointestinal tract, comprising mainly Crohn disease (CD) and ulcerative colitis (UC). Both of them are frequently encountered in children, being multifactorial conditions, with an unclear etiology. PATIENTS CONCERNS: We present 4 cases of inflammatory bowel disease (IBD) in children in order to underline the variable evolution depending on the patient's particularities. DIAGNOSIS, INTERVENTIONS AND OUTCOMES: The first case, a 13-year-old male patient, with a history of Henoch-Schonlein purpura, was admitted for rectal bleeding and weight loss, with normal laboratory parameters...

BACKGROUND: Inflammatory bowel disease can develop in the context of some rheumatic diseases in childhood, including juvenile idiopathic arthritis (JIA). Inflammatory bowel disease (IBD) is frequently associated with other immune-mediated diseases; however, systemic onset JIA (sJIA) has not previously been connected to IBD. Treatment of sJIA has significantly changed in recent years, possibly causing changes in inflammatory patterns. Therefore, data from the German Center for Pediatric and Adolescent Rheumtology from 2010 until 2015 were analyzed by retrospective chart review...

BACKGROUND & AIMS: Mucosal healing, determined by endoscopic evaluation, is one of the most important prognostic markers for patients with inflammatory bowel diseases. Findings from histologic evaluation, however, could complement findings from endoscopy in assessing mucosal responses to treatment. We analyzed long term results of children treated with thalidomide to determine the association between clinical response and histology and endoscopy findings. METHODS: We collected data from 2 multi-center trials of 70 children with refractory Crohn's disease (CD) or ulcerative colitis (UC) (2-18 years old; ileo-colonic or colonic disease) given thalidomide or placebo (NCT00720538)...

BACKGROUND: Magnetic resonance enterography (MRE) is increasingly relied upon for noninvasive assessment of intestinal inflammation in Crohn disease. However very few studies have examined the diagnostic accuracy of individual MRE signs in children. OBJECTIVE: We have created an MR-based multi-item measure of intestinal inflammation in children with Crohn disease - the Pediatric Inflammatory Crohn's MRE Index (PICMI). To inform item selection for this instrument, we explored the inter-rater agreement and diagnostic accuracy of individual MRE signs of inflammation in pediatric Crohn disease and compared our findings with the reference standards of the weighted Pediatric Crohn's Disease Activity Index (wPCDAI) and C-reactive protein (CRP)...

The incidence of Crohn's 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 existing evidence on the role of elective surgery and options in pediatric patients affected with CD. We present an expert opinion and critical review of the literature to provide evidence-based guidance to manage these patients...

INTRODUCTION: Eosinophilic colitis, which is a rare form of eosinophilic gastrointestinal diseases, occurs as primary and secondary allergic eosinophilic colitis of the gastrointestinal tract infection, inflammatory bowel disease, celiac disease, and vasculitis. The diagnosis is based on a significant amount of eosinophils in the inflammatory infiltrate of the colon wall. AIM: To analyze the clinical picture taking into account comorbidities and endoscopic picture in children with eosinophilic colitis...

IgA vasculitis is primarily a pediatric disease that is rarely encountered in adults. With adults, gastrointestinal manifestations are quite common, yet are nonspecific and may overlap with other diseases, particularly Crohn's disease, which can make the diagnosis a challenging task. Treatment is controversial given the disease course is usually self-limited with few serious complications. We present a case of IgA vasculitis in an adult patient with limited extraintestinal findings illustrating the complexity of arriving at the correct diagnosis...

OBJECTIVE: Intestinal surgery is an important part of Crohn's disease (CD) treatment in children. The aim of this study was to compare the rate of endoscopic recurrence at the 6 month after ileocecal resection (ICR) in children with CD treated with azathioprine (AZA) between patients who received prior anti-tumor necrosis factor alpha (anti-TNF-α) therapy and those who were not administered this therapy. Moreover, we tried to identify the potential risk factors for disease recurrence and describe the schedule of long-term follow-up after surgery...

OBJECTIVES: There is no model for the process of transition of adolescents with inflammatory bowel diseases (IBD) to the adult care protocol. We recently established a transition clinic where 17-year-old to 18-year-old IBD patients are seen by a multidisciplinary team including pediatric and adult gastroenterologists with expertise in IBD treatments, an IBD nurse, and a psychologist. We quantitatively describe this model and its benefits, and correlate demographic and transition parameters to self-efficacy in IBD adolescent patients before and after transition...
