With the increasing number of children with inflammatory bowel disease (IBD), very earlyonset 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. 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. The diagnosis of VEO-IBD requires endoscopic and histological evaluations. However, satisfactory small bowel imaging studies may not be feasible in this small population. Both genetic and immunological approaches are necessary for the diagnosis of MD-IBD, which can differ among countries according to the available resources. 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. Proper management of VEO-IBD by pediatric gastroenterologists constitutes a challenge. Some MD-IBDs can be curable by allogenic hematopoietic stem cell transplantation. With an understanding of the affected gene functions, targeted therapies are being developed.Social and psychological support systems for both children and their families should also be provided to improve their quality of life. Multidisciplinary team care would contribute to early diagnosis, proper therapeutic interventions, and improved quality of life in patients and their families.

Purpose: Golimumab (GLM) is an anti-tumor necrosis factor (TNF)-α antibody preparation known to be less immunogenic than infliximab (IFX) or adalimumab. Few reports on GLM in pediatric patients with ulcerative colitis (UC) are available. This study aimed to review the long-term durability and safety of GLM in a pediatric center. Methods: The medical records of 17 pediatric patients (eight boys and nine girls) who received GLM at the National Center for Child Health and Development were retrospectively reviewed. Results: The median age at GLM initiation was 13.9 (interquartile range 12.0–16.3) years.Fourteen patients had pancolitis, and 11 had severe disease (pediatric ulcerative colitis activity index ≥65). Ten patients were biologic-naïve, and 50% achieved corticosteroid-free remission at week 54. Two patients discontinued prior anti-TNF-α agents because of adverse events during remission. Both showed responses to GLM without unfavorable events through week 54. However, the efficacy of GLM in patients who showed primary nonresponse or loss of response to IFX was limited. Four of the five patients showed non-response at week 54. Patients with severe disease had significantly lower corticosteroid-free remission rate at week 54 than those without severe disease. No severe adverse events were observed during the study period. Conclusion GLM appears to be safe and useful for pediatric patients with UC. Patients with mild to moderate disease who responded to but had some adverse events with prior biologics may be good candidates for GLM. Its safety and low immunogenicity profile serve as favorable options for selected children with UC.

Purpose: The development of assistive devices has allowed for the performance of capsule endoscopy in children. Anticipating the capsule’s transit time could affect the efficacy of the investigation and potentially minimize the fasting period. This study determined the predictors of small bowel transit time for small-bowel capsule endoscopy in children and adolescents with inflammatory bowel disease. Methods: We retrospectively examined children and adolescents with inflammatory bowel disease who underwent capsule endoscopy by the age 18 at a Japanese tertiary care children’s hospital. Small bowel transit time predictors were analyzed using multiple regression with explanatory variables. Results: Overall, 92 patients, aged 1–17 years, with inflammatory bowel disease (63 Crohn’s disease and 29 ulcerative colitis cases) were examined for factors affecting small bowel transit time. In the simple regression analysis, diagnosis, age, height, weight, serum albumin, general anesthesia, and small intestine lesions were significantly associated with small bowel transit time. In the multiple regression analyses, serum albumin (partial regression coefficient: −58.9, p=0.008), general anesthesia (partial regression coefficient: 127, p<0.001), and small intestine lesions (partial regression coefficient: 30.1, p=0.037) showed significant associations with small bowel transit time. Conclusion Hypoalbuminemia, the use of general anesthesia for endoscopic delivery of the capsule, and small intestine lesions appeared to be predictors of prolonged small bowel transit time in children and adolescents with inflammatory bowel disease. Expecting the finishing time may improve examination with a fasting period reduction, which benefits both patients and caregivers.

Purpose: The impact of coronavirus 2019 (COVID-19) on gastrointestinal (GI) endoscopy procedures in adults has been reported, with a drastic reduction in the number of procedures.However, there are no sufficient data regarding the impact on pediatric GI endoscopy. Here, we aimed to report that impact in the Asia-Pacific region. Methods: A questionnaire-based internet survey was conducted from June to November 2021 among pediatric endoscopy institutions in the Asia-Pacific region, with each institution providing a single response. Overall, 25 questions focused on the impact of the number of procedures conducted, the usage of personal protective equipment (PPE), and endoscopy training programs during the pandemic. Results: A total of 162 institutions across 13 countries in the Asia-Pacific region participated in the study, and 133 (82.1%) institutions underwent procedure changes since the emergence of COVID-19. The number of esophagogastroduodenoscopy and ileocolonoscopy procedures decreased in 118/133 (88.7%) and 112/133 (84.2%) institutions, respectively. Endoscopy for patient with positive COVID-19 in an emergency or urgent cases still carried out in 102/162 (62.9%) institutions. Screening of COVID-19 for all patients before endoscopy was done across 110/162 (67.9%) institutions. PPE recommendations varied among institutions.Pediatric gastrointestinal endoscopy training programs were discontinued in 127/162 (78.4%) institutions. Conclusion This study reports the impact of the COVID-19 pandemic on pediatric gastrointestinal endoscopy in the Asia-Pacific region. There has been a significant reduction in the number of endoscopic procedures and relevant training programs.

Purpose: The parents of adolescents with inflammatory bowel disease may experience impaired mental health and quality of life. This longitudinal study aimed to verify whether the mental health and quality of life of the parents of adolescents with inflammatory bowel disease declined when their children had active disease. Methods: Sociodemographic data, parental anxiety, depression, and quality of life were analyzed using validated questionnaires for each variable. After the baseline survey, the second and follow-up surveys were conducted at 3 and 12 months, respectively. The active disease group comprised eight parents whose children had active disease during the baseline and second surveys. The remission group comprised 14 parents whose children remained in remission during both surveys. The improved group comprised nine parents whose children experienced active disease at baseline and remission during the second survey. Parental mental health and quality of life were compared among the groups. Results: Significantly higher levels of anxiety were observed in the active disease group in all surveys (p<0.050). Although depression levels and quality of life did not differ significantly among the three groups, pairing the active disease group with other groups showed some large effect sizes. Conclusion Parents tended to experience decreased mental health and quality of life when their adolescents experienced active inflammatory bowel disease. Consequently, our hypothesis was partially verified. Therefore, parents need support when their children have active disease; this finding highlights the need for parental support systems.

Purpose: Pediatric gastrointestinal (GI) endoscopy significantly contributes to the diagnosis and management of GI diseases in children. Global data on pediatric GI endoscopy in the Asia-Pacific region are limited. We aimed to report the findings of a regional survey on pediatric endoscopy in the Asia-Pacific region. Methods: A questionnaire-based survey involving GI endoscopy centers in 13 Asia-Pacific countries (June to November 2021). The questionnaires included annual procedure volumes (from basic diagnostics to advanced therapeutic endoscopy), endoscopists, sedation procedures, and national training programs. Results: A total of 162 GI endoscopy centers completed the survey. All centers performed basic endoscopies (esophagogastroduodenoscopy and ileocolonoscopy); however, 45.1% and 59.1% of the centers performed less than 50 esophagogastroduodenoscopies and ileocolonoscopies per year, respectively. Small bowel evaluation (capsule endoscopy or balloon-assisted enteroscopy) was performed in 59.3% of the centers. Foreign body removal, polypectomy, and percutaneous endoscopic gastrostomy were performed in 89.5%, 85.8%, and 52.5% of centers, respectively. Endoscopic hemostatic interventions, which are lifesaving procedures, included glue injection (30.9%), hemostasis of nonvariceal bleeding (65.4%), and endoscopic variceal ligation (70.4%). Pediatric GI endoscopy is performed not only by pediatric gastroenterologists but also by adult gastroenterologists in 21–50% of centers for many kinds of procedures. Sedation was provided by anesthesiologists in 65.4% of the centers. Most centers offer both adult and pediatric endoscopy training. Conclusion The study highlights regional disparities in pediatric GI endoscopy services. It emphasizes the need for expanded pediatric GI training and improved access to therapeutic endoscopy, particularly for life-saving procedures.
