Very early-onset inflammatory bowel disease (VEO-IBD) is defined as IBD diagnosed in children younger than 6 years of age. VEO-IBD is often associated with a monogenic etiology or primary immune deficiency. Here, we report the case of a 7-month-old Chinese girl diagnosed with VEO-IBD who had a variant in the interleukin-10 receptor A (IL-10-RA) gene. The patient presented with recurrent fevers, abdominal pain, diarrhea, perianal abscesses, and oral ulcers. Whole-exome sequencing (WES) identified a novel compound heterozygote mutation, c.395T>G (p.Leu132Arg)/ex.1del (p.?), in the IL-10RA gene of the patient. The missense mutation c.395T>G (p.Leu132Arg) was inherited from her mother, and ex.1del (p.?) was inherited from her father. Neither mutation has been reported previously. The IL-10RA function of the patient was defective, as demonstrated by a failure of signal transducer and activator of transcription 3 (STAT3) activation in peripheral blood mononuclear cells (PBMCs) stimulated with recombinant IL-10. The patient underwent matched unrelated peripheral blood hematopoietic stem cell transplantation (HSCT), and the clinical manifestations were dramatically improved. In summary, we identified a novel compound heterozygote mutation, c.395T>G (p.Leu132Arg)/ex.1del (p.?), in IL-10RA that caused VEO-IBD in a Chinese child, which further expands the mutational spectrum of IL-10RA.

Abstract Very early onset inflammatory bowel disease (VEO-IBD) is defined as IBD presenting before 6 years of age. When compared with IBD diagnosed in older children, VEO-IBD has some distinct characteristics such as a higher likelihood of an underlying monogenic etiology or primary immune deficiency. In addition, patients with VEO-IBD have a higher incidence of inflammatory bowel disease unclassified (IBD-U) as compared with older-onset IBD. In some populations, VEO-IBD represents the age group with the fastest growing incidence of IBD. There are contradicting reports on whether VEO-IBD is more resistant to conventional medical interventions. There is a strong need for ongoing research in the field of VEO-IBD to provide optimized management of these complex patients. Here, we provide an approach to diagnosis and management of patients with VEO-IBD. These recommendations are based on expert opinion from members of the VEO-IBD Consortium (www.VEOIBD.org). We highlight the importance of monogenic etiologies, underlying immune deficiencies, and provide a comprehensive description of monogenic etiologies identified to date that are responsible for VEO-IBD.

Abstract Background Inflammatory bowel diseases are characterized by chronic inflammation of the gastrointestinal tract. In particular, Crohn disease and ulcerative colitis represent the two most common types of clinical manifestations. Extraintestinal manifestations of inflammatory bowel diseases represent a common complications, probably reflecting the systemic inflammation. Renal involvement is reported in 4–23% of cases. However, available data are limited to few case series and retrospective analysis, therefore the real impact of renal involvement is not well defined. Case presentation We report the case of a 10-years old male affected by very early onset unclassified-Inflammatory bowel diseases since he was 1-year old, presenting with a flare of inflammatory bowel diseases associated with acute kidney injury due to granulomatous interstitial nephritis. Of interest, at 7-year-old, he was treated for IgA nephropathy. To our knowledge, no previous reports have described a relapse of renal manifestation in inflammatory bowel diseases, characterized by two different clinical and histological phenotypes. Conclusions The link between the onset of kidney injuries with flares of intestinal inflammation suggest that nephritis maybe considered an extra-intestinal manifestation correlated with active inflammatory bowel disease. However, if granulomatous interstitial nephritis represents a cell-mediated hypersensitivity reaction than a true extraintestinal manifestation of inflammatory bowel diseases is still not clarified. We suggest as these renal manifestations here described may be interpreted as extraintestinal disorder and also considered as systemic signal of under treatment of the intestinal disease.

Abstract Currently over 70 genes known to be causative in very early onset inflammatory bowel disease (VEOIBD) have been identified. In the current issue of Inflammatory Bowel Diseases, 2 articles describing monogenetic forms of VEOIBD are highlighted. One describes a patient with life-threatening VEOIBD and a mutation in ITGA6, illustrating the importance of the epithelial barrier in maintaining mucosal homeostasis. The other describes the presentation and management of 10 patients with VEOIBD secondary to damaging mutations in MVK, resulting in mevalonate kinase deficiency. Though most monogenic causes of VEOIBD remain “private,” understanding the different categories of pathways affected in children with VEOIBD is critical and has already resulted in invaluable insight in the management of patients with VEOIBD and may hold strong implications for the care of IBD overall.

Background: Very early-onset inflammatory bowel disease (VEO-IBD) is defined as diagnosis of Ulcerative Colitis (UC) or Crohn’s Disease (CD) in children under six years of age. Genome wide association studies have linked a strong genetic component responsible for VEO-IBD. Approximately, 30-40% children of VEO-IBD have underlying immunodeficiency states. We aimed to study the spectrum of presentation, underlying monogenetic defects and outcome in VEO-IBD. Methods: This is a prospective, observational study conducted at division of Gastroenterology, the Children's Hospital & the Institute of Child Health, Lahore, over 2 years. Children developing features of IBD under six-years of age were included. Data included demography, clinical presentation, diagnostic tools and outcome. Gastroscopy and colonoscopy were performed in all patients in addition to basic work up done for associatedimmunodeficiency states and molecular genetics.  SPSS version 21 was used for analysis.
