BACKGROUND: Immune deficiencies have been associated with inflammatory bowel disease (IBD), and are reported to be particularly enriched in patients with very early-onset IBD (VEO-IBD). However, the actual frequency of primary immune deficiencies in an unselected cohort of patients with VEO-IBD is not known, nor is the optimal screening approach for this population. This study was undertaken to identify a diagnostic approach that will enhance identification of children with primary immune deficiencies who present with VEO-IBD...

BACKGROUND: Very early onset inflammatory bowel disease (VEOIBD) (inflammatory bowel disease [IBD] before 6 years of age) may manifest as a monogenic disease affecting the gastrointestinal tract. Syndromic diarrhea/trichohepatoenteric syndrome (SD/THE), a rare disorder caused by alteration of a complex involved in RNA degradation, has been reported to present with some degree of colitis and in some cases an IBD-like presentation. METHODS: We reviewed clinical and biological data of 4 previously published cases and added detailed data of 2 new cases of SD/THE with an IBD-like presentation...

Mice deficient in glutathione peroxidase (GPx)-1 and -2 (GPx1(-/-)GPx2(-/-) double knockout or DKO mice) develop very-early-onset (VEO) ileocolitis, suggesting that lack of defense against reactive oxygen species (ROS) renders susceptibility to intestinal inflammation. Two members of ROS-generating NADPH oxidase family, NOX1 and DUOX2, are highly inducible in the intestinal epithelium. Previously, we reported that Nox1 deficiency ameliorated the pathology in DKO mice (Nox1-TKO). The role of Duox2 in ileocolitis of the DKO mice is evaluated here in Duoxa-TKO mice by breeding DKO mice with Duoxa(-/-) mice (Duoxa-TKO), which do not have Duox2 activity...

BACKGROUND AND AIMS: Very-early-onset inflammatory bowel disease [VEO-IBD] is a form of IBD that is distinct from that of children with an older onset. We compared changes over time in the incidence and phenotype at diagnosis between two groups according to age at IBD diagnosis: VEO-IBD diagnosed before the age of 6 years, and early-onset IBD [EO-IBD] diagnosed between 6 and 16 years of age. METHODS: Data were obtained from a cohort enrolled in a prospective French population-based registry from 1988 to 2011...

PURPOSE: Pediatric inflammatory bowel disease (IBD) is a heterogeneous disorder caused by multiple factors. Although genetic and immunological analyses are required for a definitive diagnosis, no reports of a comprehensive genetic study of a Japanese population are available. METHODS: In total, 35 Japanese patients <16 years of age suffering from IBD, including 27 patients aged <6 years with very early-onset IBD, were enrolled in this multicenter study. Exome and targeted gene panel sequencing was performed for all patients...

Alterations of immune homeostasis in the gut may result in development of inflammatory bowel disease. A five-month-old girl was referred for recurrent respiratory and genitourinary tract infections, sepsis in neonatal period, chronic diarrhea, perianal abscess, rectovaginal fistula, and hyperemic skin lesions. She was born to second-degree consanguineous, healthy parents. Her elder siblings were lost at 4 months of age due to sepsis and 1 year of age due to inflammatory bowel disease, respectively. Absolute neutrophil and lymphocyte counts, immunoglobulin levels, and lymphocyte subsets were normal ruling out severe congenital neutropenia and classic severe combined immunodeficiencies...

BACKGROUND: Most cases of inflammatory bowel disease (IBD) are caused by complex host-environment interaction. There are a number of conditions associated with a single-gene mutation, most cases are very early onset (aged < 6 yr), present with a unique form of disease and often have atypical features. METHODS: Whole-exome data for 147 pediatric patients with IBD were interrogated for a panel of 51 genes associated with monogenic IBD. Observed variation was categorized according to the American College of Medical Genetics (ACMG) guidelines to identify rare, novel, and known variants that might contribute to IBD...

AIM: To perform sequencing analysis in patients with very early-onset inflammatory bowel disease (VEO-IBD) to determine the genetic basis for VEO-IBD in Chinese pediatric patients. METHODS: A total of 13 Chinese pediatric patients with VEO-IBD were diagnosed from May 2012 and August 2014. The relevant clinical characteristics of these patients were analyzed. Then DNA in the peripheral blood from patients was extracted. Next generation sequencing (NGS) based on an Illumina-Miseq platform was used to analyze the exons in the coding regions of 10 candidate genes: IL-10, IL-10RA, IL-10RB, NOD2, FUT2, IL23R, GPR35, GPR65, TNFSF15, and ADAM30...

OBJECTIVES: Inflammatory bowel disease [IBD] presenting in early childhood is extremely rare. More recently, progress has been made to identify children with monogenic forms of IBD predominantly presenting very early in life. In this study, we describe the heterogeneous phenotypes and genotypes of patients with IBD presenting before the age of 2 years and establish phenotypic features associated with underlying monogenicity. METHODS: Phenotype data of 62 children with disease onset before the age of 2 years presenting over the past 20 years were reviewed...

INTRODUCTION: The incidence of inflammatory bowel disease (IBD) has increased over the last 50 years. It is now recognized that several genetic defects can express an IBD-like phenotype at very early onset (<6 years). AREAS COVERED: The aim of this review was to update knowledge concerning the specificity of IBD at onset <6 years, which can include conventional/standard IBD as well as monogenic IBD-like diseases. Expert commentary: We found that females are less prone than males to develop monogenic disorders, which have X-linked heritability in several cases...

Interleukin-10 receptor [IL10R] mutations are associated with severe childhood inflammatory bowel disease [IBD]. Two unrelated patients who died of very early-onset severe IBD and sepsis were identified as harbouring the same compound heterozygous mutations in IL10RA [p.R101W; p.T179T]. A third patient was found to be homozygous for p.T179T. The missense change of p.R101W has been reported. The synonymous change of p.T179T, with a minor allele frequency of 0.035% in the population, was novel. The p.T179T mutation was located before the 5' splice donor site, leading to exon skipping and out-of-frame fusion of exons 3 and 5, causing altered STAT3 phosphorylation in IL10-induced peripheral blood mononuclear cells...

BACKGROUND: The objectives of this multicenter national study were to compare the clinical phenotype of early-onset inflammatory bowel disease (IBD) (EO-IBD) with IBD in older children and to examine whether there is any variability in consanguinity rate and familial aggregation in EO-IBD compared with later onset IBD. METHODS: A retrospective analysis was performed on children aged 0 to 14 years with IBD in 17 centers located in geographically distinct regions in Saudi Arabia, from 2003 to 2012...

BACKGROUND: Very early onset inflammatory bowel disease (VEO-IBD) is frequently considered a different disease process than older onset IBD. The severe phenotype and young age of onset suggest a more pronounced genetic susceptibility and dysregulated immune response. We hypothesized that rare or novel variants involving pathways in barrier defense, autoimmunity as well as both B and T cell development and activation, were enriched in patients with VEO-IBD. In turn, these variants result in altered gene expression, impaired immunological responses, and aberrant host-microbe interactions...

BACKGROUND & AIMS: Severe forms of inflammatory bowel disease (IBD) that develop in very young children can be caused by variants in a single gene. We performed whole-exome sequence (WES) analysis to identify genetic factors that might cause granulomatous colitis and severe perianal disease, with recurrent bacterial and viral infections, in an infant of consanguineous parents. METHODS: We performed targeted WES analysis of DNA collected from the patient and her parents...

BACKGROUND: Aggressive course and resistance to treatments usually characterize very early onset inflammatory bowel disease (VEO-IBD). Some VEO-IBD cases are due to monogenic immune defects and can benefit from hematopoietic stem cell transplantation (HSCT).
