411 pediatrics1/7/2024 Monogenic or Mendelian disorder-associated IBD (MD-IBD) is a term used to represent IBD caused by genetic mutations. Recent advances in genetic evaluation have enabled the identification of gene mutations that are responsible for some forms of IBD. However, some children with VEO-IBD are known to also have diseases with monogenic etiologies. IBD, in general, is regarded as a polygenic disease, and a genome-wide association study revealed >230 known disease-associated genes. Given their phenotypic heterogeneity and various responses to the conventional IBD treatments, differentiating VEO-IBD as Crohn's disease (CD) or ulcerative colitis (UC) posed a challenge for pediatric gastroenterologists. Some studies define VEO-IBD as IBD with an onset before 6 years of age, probably because the duration between the onset and diagnosis of IBD varies depending on the level of suspicion and availability of medical resources. Furthermore, IBD cases with an onset by 2 years and 28 days of age were classified as infantile- and neonatal-onset IBDs, respectively. Among A1a cases, those diagnosed before 6 years of age are classified as very early-onset IBD (VEO-IBD). ![]() In the Paris classification, the pediatric classification created by the Porto group of the European Society for Paediatric Gastroenterology Hepatology and Nutrition, A1 is further divided into A1a (diagnosed before 10 years of age) and A1b (diagnosed between 10 and 17 years of age). In the Montreal classification, cases diagnosed before 17 years of age were distinguished as pediatric-onset IBD, A1. Patients with IBD can be categorized by age at diagnosis. Owing to the atypical phenotypes and clinical course, and the increasing number of children with inflammatory bowel disease (IBD), patients who had an onset of IBD during infancy or young childhood were regarded as a unique group. Multidisciplinary team care would contribute to early diagnosis, proper therapeutic interventions, and improved quality of life in patients and their families. Social and psychological support systems for both children and their families should also be provided to improve their quality of life. With an understanding of the affected gene functions, targeted therapies are being developed. Some MD-IBDs can be curable by allogenic hematopoietic stem cell transplantation. Proper management of VEO-IBD by pediatric gastroenterologists constitutes a challenge. As a result of the use of targeted gene panels covered by the national health insurance and the nationwide research project investigating inborn errors of immunity, an efficient approach for the diagnosis of MD-IBD has been developed in Japan. Both genetic and immunological approaches are necessary for the diagnosis of MD-IBD, which can differ among countries according to the available resources. ![]() However, satisfactory small bowel imaging studies may not be feasible in this small population. ![]() The diagnosis of VEO-IBD requires endoscopic and histological evaluations. Advances in genetic testing have enabled the diagnosis of IBD caused by gene mutations, also known as monogenic or Mendelian disorder-associated IBD (MD-IBD), with approximately 60 causative genes reported to date. to 5 p.m.With the increasing number of children with inflammatory bowel disease (IBD), very early-onset IBD (VEO-IBD), defined as IBD that is diagnosed or that develops before 6 years of age, has become a field of innovation among pediatric gastroenterologists. University of Iowa Stead Family Children’s Hospital All evening/weekend urgent visits are seen at 411 10th Street S.E. Our pediatricians are members of the University of Iowa Stead Family Children’s Hospital team, which means they work hand-in-hand with all pediatric specialists at UI Stead Family Children’s Hospital. Pediatricians provide a range of services from well-child care, to basic childhood immunizations and illnesses, to managing complex medical conditions and chronic disorders. Pediatricians specialize in the care of infants, children, and adolescents.
