Abstract
BACKGROUND AND AIM Even with increasing numbers of biologic agents available for management of ulcerative colitis (UC), infliximab (IFX) retains an important place in treatment of pediatric patients with this disease. As few reports have addressed outcomes in pediatric UC patients who had to discontinue IFX, we examined clinical course and prognosis after IFX failure in pediatric UC. METHODS A prospective cohort study of pertinent cases enrolled in the Japanese Pediatric Inflammatory Bowel Disease Registry between 2012 and 2020 was conducted to determine outcomes for pediatric UC patients who received IFX but required its discontinuation during follow-up (IFX failure). RESULTS Of the 301 pediatric UC patients in the registry, 75 were treated with IFX; in 36 of these, IFX was discontinued during follow-up. Severity of UC at onset and absence of concomitant immunomodulator therapy were significant risk factors for IFX failure (P = 0.005 and P = 0.02, respectively). The cumulative colectomy rate after IFX failure was 41.3% at 1 year and 47.5% at 2 years. Colectomy was significantly more frequent when IFX was discontinued before June 1, 2018, than when IFX was discontinued later (P = 0.013). This difference likely involves availability of additional biologic agents for treatment of UC beginning in mid-2018 (P = 0.005). CONCLUSION In pediatric UC patients, approximately 50% underwent colectomy during a 2-year interval following IFX failure. Prognosis after IFX failure appeared to improve with availability of new biologic agents and small-molecule drugs in mid-2018.

Abstract
BACKGROUND SLCO2A1 encodes a prostaglandin (PG) transporter, and autosomal recessive pathogenic variants of this gene cause chronic enteropathy associated with SLCO2A1. It is unclear whether a heterozygous pathogenic variant of SLCO2A1 has a role in the pathogenesis of other types of inflammatory bowel disease (IBD). In this study, we investigated the possible involvement of a local epigenetic alteration in SLCO2A1 in patients with a heterozygous pathogenic variant. METHODS We conducted whole-exome sequencing of samples from 2 sisters with suspected monogenic IBD. In addition, we performed bisulfite sequencing using DNA extracted from their small and large intestine samples to explore epigenetic alterations. RESULTS A heterozygous splicing site variant, SLCO2A1:c.940 + 1G > A, was detected in both patients. To explore the possible involvement of epigenetic alterations, we analyzed protein and messenger RNA expression of SLCO2A1, and observed attenuated SLCO2A1 expression in the inflamed lesions of these patients compared with that in the control individuals. Furthermore, bisulfite sequencing indicated dense methylation in the promoter region of SLCO2A1 only in the inflamed lesions of both patients. The urinary PG metabolite levels in these patients were comparable to those in patients with chronic enteropathy associated with SLCO2A1 and higher than those in the control individuals. We found considerably higher levels of the metabolites in patient 1, who showed more severe symptoms than patient 2. CONCLUSIONS Local DNA methylation attenuated SLCO2A1 expression, which may evoke local inflammation of the mucosa by the unincorporated PG. These findings may improve our understanding of the epigenetic mechanisms underlying IBD development.

Abstract
INTRODUCTION The pathophysiology of irritable bowel syndrome (IBS) remains unknown. This study aimed to evaluate colonic motility and serotonin system response to restraint stress (RS) among adolescent rats who underwent neonatal maternal separation (NMS) to clarify the features of pathogenesis in adolescents with IBS. METHODS Male rats were exposed to NMS as chronic stress, and a normally handled (NH) group was used as control. Four groups were created by adding RS as acute stress treatment to the NMS and NH groups. To realize the RS treatment, the subjects were restrained for 1 h at the age of 5 weeks, and hourly fecal pellet discharge was determined. After euthanization and proximal colon intestinal tissue collection, 5-hydroxytryptamine (5-HT) and 5-hydroxytryptamine receptor 3 (5-HT3R) concentrations, enterochromaffin (EC) cell density, and the expression of mRNA-encoding slc6a4 were examined. RESULTS The amount of fecal pellet discharge during RS increased significantly in the RS and NMS+RS groups compared with that in the NH and NMS groups, respectively. The 5-HT concentration in the intestinal tissue of rats in the RS and NMS groups increased significantly compared with that of rats in the NH group. EC cell density also increased significantly in the NMS and NMS+RS groups compared with that in the NH and RS groups. However, combined stress did not result in any significant differences in the expression of 5-HT3R and mRNA-encoding slc6a4. CONCLUSIONS The combination of juvenile and acute stress effectively induced increased 5-HT concentration or EC cell density via the 5-HT pathway in the proximal colon of adolescent rats.

Abstract
BACKGROUND Patients with inflammatory bowel disease (IBD) are at a higher risk of developing cardiovascular diseases than healthy individuals, owing to persistent chronic inflammation and treatment effects. This study aimed to assess left ventricular function in patients with childhood-onset IBD using layer-specific strain analysis and to identify early indicators of cardiac dysfunction in them. METHODS A total of 47 patients with childhood-onset ulcerative colitis (UC), 20 patients with Crohn's disease (CD), and 75 age- and sex-matched healthy control subjects were included in this study. Conventional echocardiographic measurements of layer-specific (ie, endocardium, midmyocardium, and epicardium) global longitudinal strain and global circumferential strain (GCS) were evaluated in these participants. RESULTS Layer-specific strain analysis showed that global longitudinal strain was lower in all layers for the UC (P < .001) and CD (P < .001) groups, regardless of the age at onset, but that GCS was only lower in the midmyocardial (P = .032) and epicardial (P = .018) layers in the CD group than in the control group. Although the mean left ventricular wall thickness was not significantly different among the groups, it was significantly correlated with the GCS of the endocardial layer in the CD group (ρ= -0.615; P = .004), suggesting that thickening of the left ventricular wall occurred as a compensatory mechanism to maintain the endocardial strain in the CD group layer. CONCLUSIONS Children and young adults with childhood-onset IBD displayed decreased midmyocardial deformation. Layer-specific strain could also be useful to identify indicators of cardiac dysfunction in patients with IBD.

Abstract
We investigated the effectiveness of cap-assisted colonoscopy conducted with the patient in the left lateral decubitus position at both the colonoscope's insertion and withdrawal timepoints compared to the effectiveness of colonoscopy without a cap conducted in the supine position at withdrawal. This was a case-control study, based on historical comparisons of patients over 2 time periods. The first group of patients underwent colonoscopies with a transparent cap and the patient was in the left lateral decubitus position at both the insertion and withdrawal timepoints from April to June 2019. The subsequent group underwent colonoscopies without a cap and with the patient in the supine position at withdrawal from July to September 2019. The rates of successful intubation, cecal intubation time, and number, size, shape, and location of the detected adenomas and sessile serrated lesions were compared between the 2 groups. Data from 644 colonoscopies (cap-assisted colonoscopy + left lateral decubitus position, n=320; other colonoscopies, n=324) were analyzed. The demographic characteristics and technical performances were similar. The SSL detection rate was significantly higher with cap-assisted colonoscopy and the left lateral decubitus position than with other colonoscopies (3.4% vs 0.93%, P=.029). The adenoma detection rates in the 2 groups were similar (31% and 28%, respectively, P=.43).Cap-assisted colonoscopy in the left lateral decubitus position may increase the detection rate of sessile serrated lesions compared to colonoscopy without a cap and supine position at withdrawal.

Abstract
BACKGROUND Transabdominal ultrasonography and transperineal ultrasonography (TPUS) appear correspond to colonoscopy (CS) for evaluating ulcerative colitis (UC) activity, but their utility in UC diagnosis remains unclear. This research compared the accuracy of TPUS and CS for assessing rectal activity and differentiating noninflammatory bowel disease proctitis from UC in pediatric cases. METHODS The study is a blinded, prospective, and controlled trial. Prospectively, values of fecal calprotectin (FCP) and findings of the TPUS and CS were compared between child cases of UC and non-IBD proctitis. Findings of rectal wall thickening (RWT), rectal wall flow (RWF) on power Doppler, and microvascular signal at wall circumference (MSWC) on monochrome superb microvascular imaging assessed using TPUS were compared with the CS. RESULTS Thirty patients with Mayo endoscopic subscore (MES) 0 to 1 UC, 57 with MES 2 to 3 UC, and 44 with proctitis were registered. Fecal calprotectin, RWF, and MSWC indicated significant differences among the groups (P < .05). Rectal wall thickening showed no significant difference between MES 0-1 and proctitis (P = .76). Rectal wall thickening and MSWC were independent predictors of endoscopic activity of UC, resulting in a sensitivity and specificity of 100% for RWT ≥4.5 mm and positive MSWC. Fecal calprotectin and RWF were independent predictors for differentiating MES 0 to 1 and proctitis, and FCP and RWT were independent predictors for differentiating MES 2 to 3 and proctitis. Sensitivity and specificity were 77.2% and 80.9%, respectively, for FCP >242.5 μg/g and RWF negative; and they were both 100% for RWT >4.1 mm and MSWC positive. CONCLUSIONS Transperineal ultrasonography with mSMI may enable the evaluation of rectal activity and differentiation of UC from non-IBD proctitis with accuracy comparable to endoscopy.

Abstract
BACKGROUND Vedolizumab (VDZ) is a humanized monoclonal antibody that binds to α4β7 integrin expressed in T-lymphocytes and is gut selective. Few studies have evaluated the safety and efficacy of VDZ in pediatric ulcerative colitis (UC) patients, especially from Asia. METHODS A longitudinal multicenter retrospective study was conducted at 10 Japanese tertiary medical institutions. Patients aged ≤18 years old who received VDZ for UC between January 2019 and July 2021 were enrolled. Information on the clinical characteristics, prior/concomitant treatment, and safety during the observation period was collected. RESULTS The data obtained from 48 patients (males, n = 30; females, n = 18) were analyzed. The median age at VDZ induction was 14 (range 4-18) years old. VDZ was indicated in 73% of patients as switching from previous biologics due to primary failure, loss of response, and adverse events (AEs) and was the first biologic in 27%. Remission was achieved or maintained at weeks 14, 30, and 54 in 79.2%, 75.0%, and 65.8% of patients, respectively. There were no significant differences between the number of previous biologics exposures and VDZ effectiveness. The hematocrit, serum albumin concentrations, and erythrocyte sedimentation rate (ESR) at baseline differed significantly by VDZ effectiveness. Nine AEs, including infusion reaction, were noted in seven (14.3%) patients. There were no severe AEs related to VDZ administration. CONCLUSIONS VDZ was safe and effective in children with UC. The hematocrit, albumin, and ESR at VDZ initiation might be predictors for VDZ effectiveness. VDZ may be an important option for pediatric patients and can be used as an alternative to immunomodulators.

Abstract
Reports of food protein-induced enterocolitis syndrome (FPIES) in Japan have been increasing. However, the disease itself and the treatment options are poorly understood by both patients and medical professionals. The objective of this study is to develop an action plan for acute FPIES in Japan. We prepared a single-sheet action plan that describes the management of acute FPIES episodes for caregivers on one side and medical professionals on the reverse side. To evaluate the content of the action plan, we distributed a questionnaire to caregivers of patients with FPIES and to physicians who would encounter patients with FPIES. Changes to the FPIES action plan were made based on the feedback from the participants. The Delphi method was utilized to finalize the action plan. The participants of the initial survey found the action plan to be useful but the process for determining severity to be impractical. After discussion, the authors made appropriate improvements. By the Delphi method, consensus was reached on the revised FPIES action plan. In conclusion, this Japanese FPIES action plan was created by physicians from multiple subspecialties and caregivers of patients with FPIES. The action plan may improve the management of acute FPIES reactions in the Japanese community.

Abstract
BACKGROUND The use of grafts from donors after cardiac death (DCD) would greatly contribute to the expansion of the donor organ pool. This study aims to determine the benefits of extracorporeal membrane oxygenation (ECMO) and hypothermic oxygenated machine perfusion (HOPE) in a large animal model of DCD liver. METHODS After cardiac arrest, the abdominal aorta and the inferior vena cava were cannulated and connected to an ECMO circuit. Porcine livers were perfused in situ with ECMO at 22°C for 60 minutes after 45 minutes of cardiac death. Then, the livers were perfused for 4 hours by cold storage (CS) or HOPE. In group 1, non-in situ ECMO and grafts were preserved by HOPE. In group 2, in situ ECMO and grafts were preserved by HOPE. In group 3, in situ ECMO and grafts were preserved by CS. After preservation, all grafts were evaluated using an isolated reperfusion model (IRM) with autologous blood for 2 hours. RESULTS During HOPE, aspartate aminotransferase (AST) levels and hepatic arterial pressure in group 2 tended to be lower than in group 1. Hematoxylin-eosin staining findings after HOPE showed more massive sinusoidal congestion and hepatocyte cytoplasmic vacuolization in group 1 than in group 2. The AST and LDH levels in group 2 at the start-up of IRM tended to be lower than in group 1. CONCLUSIONS The combined use of in situ subnormothermic ECMO and HOPE is essential for the functional recovery of DCD liver grafts.

Abstract
The frequency of split cord malformation (SCM) is approximately 1 in 5000 births; however, patients are rarely diagnosed with SCM in the neonatal period. Moreover, there have been no reports of SCM with hypoplasia of the lower extremities at birth. A 3-day-old girl was transferred to our hospital for a thorough examination of hypoplasia of the left lower extremity and lumbosacral abnormalities detected after birth. The spinal magnetic resonance imaging (MRI) revealed a split spinal cord in a single dural tube. Based on the MRI findings, the patient was diagnosed with SCM type II. Following discussions with the parents, pediatricians, neurosurgeons, psychologists, and social workers, we decided to perform untethering to prevent further neurological impairment after achieving a sufficient body weight. The patient was discharged on day 25 of life. Early diagnosis and intervention may improve the neurological prognosis in terms of motor function, bladder and bowel function, and superficial sensation; thus, clinicians should report infrequent findings that may lead to SCM diagnosis. SCM should be differentiated in patients with left-right differences in the appearance of the lower extremity, particularly in those with lumbosacral abnormalities.

Abstract
BACKGROUND Eosinophilic gastrointestinal disease (EGID) is a disorder characterized by infiltration of eosinophils causing mucosal damage and dysfunction of the gastrointestinal tract. The endoscopic findings of eosinophilic enteritis (EoN), an EGID variant, are nonspecific and occasionally difficult to diagnose. In contrast, chronic enteropathy associated with SLCO2A1 (CEAS) is a chronic persistent small intestinal disorder characterized by endoscopic findings such as multiple oblique and circular ulcers.
CASE SUMMARY We report the case of a 10-year-old boy who had suffered abdominal pain and fatigue for the preceding 6 mo. He was referred to our institute for investigation of suspected gastrointestinal bleeding because of severe anemia with hypoproteinemia and positive fecal human hemoglobin. The upper and lower gastrointestinal endoscopic findings were normal; however, double-balloon small bowel endoscopy showed multiple oblique and circular ulcers with discrete margins and mild constriction of the intestinal lumen in the ileum. The findings were highly consistent with CEAS, but urine prostaglandin metabolites were within normal limits, and no previously reported mutations in the SLCO2A1 gene were identified. Histological evaluation demonstrated moderate to severe eosinophilic infiltration localized to the small intestine suggesting a diagnosis of EoN. Clinical remission was maintained with montelukast and a partial elemental diet, but emergent surgery for bowel obstruction due to small intestinal stenosis was performed two years after the initial treatment.
CONCLUSION EoN should be considered in the differential diagnosis of CEAS-like small intestinal ulcerative lesions and normal urinary prostaglandin metabolite levels.

Abstract
BACKGROUND Sedating children for magnetic resonance imaging (MRI) requires special consideration. The 2018 revision of social insurance allows additional fees to be calculated for pediatric MRIs performed under sedation in Japan. The number and trend of actual claims since this addition was established is unknown. METHODS To analyze the claims of additional fees for pediatric sedated MRI imaging after fiscal year (FY) 2018, the actual claims of the addition in inpatient and outpatient practice was analyzed using publicly-available data from the Ministry of Health, Labour and Welfare (MHLW). We analyzed the calculation rate for all MRI scans. Annual changes in the actual number and calculation rate were analyzed. The ratio of the number of additional fees to the overall number of pediatric radiological procedures was used to examine the geographic disparity. RESULTS The number of calculations from FY 2018 to FY 2020 was available; in FY 2020, only 1347 additions were calculated, corresponding to 0.35% of the total number of MRI scans. The number of fees showed a decreasing trend. Most cases were in the 0-4 years age group: however, there were a few cases in the 10-14 years age group without such a decrease. The relative number of calculations by prefecture showed a disparity of up to 14 times. CONCLUSIONS The requirements for the addition of pediatric MRI sedation are strict and not fully utilized in pediatric sedation for MRI. Measures such as relaxing the requirements for the fee are needed to make MRI-related sedation safer. (249/250words) .

Abstract
BACKGROUND AND AIMS Transabdominal ultrasonography (TAUS) appears comparable to colonoscopy for evaluating ulcerative colitis (UC) activity, but it has low accuracy in rectal evaluation. In this study, the accuracy of transperineal ultrasonography (TPUS) for evaluating rectal activity was compared to that of colonoscopy in pediatric UC cases. METHODS Fecal calprotectin (FCP) values and TPUS and colonoscopic findings were compared prospectively in pediatric UC cases. Rectal wall thickening (RWT) and rectal wall flow (RWF) on power Doppler evaluated by TPUS were compared with the colonoscopy findings and were also measured on TAUS and assessed for the concordance rate of each finding. RESULTS Thirty UC [Mayo endoscopic sub-score (MES) 0-1] cases and 57 UC (MES 2-3) cases were enrolled. FCP, RWT, and RWF showed significant differences between the two groups (p<0.05). RWT and RWF were independent predictors of UC endoscopic activity, showing sensitivity of 95.8% and specificity of 100% with RWT≥4.5 mm and positive RWF. The concordance rates between TPUS and TAUS findings in MES 2-3 were moderate to fair, whereas those in MES 0-1 were fair to poor. The concordance rates between ultrasonic examiners were good for both TAUS and TPUS. CONCLUSIONS TPUS may evaluate rectal activity of UC with accuracy comparable to endoscopy. If accurate ultrasonic screening for the total colon can be performed by TPUS and TAUS, repeated evaluation of short-term treatment response may be possible.

Abstract
BACKGROUND As best practices for treating children with severe-onset ulcerative colitis remain controversial in the era of biologic agents, we prospectively investigated treatments and outcomes in a multicenter cohort. METHODS Using a Web-based data registry maintained in Japan between October 2012 and March 2020, we compared management and treatment outcomes in an S1 group defined by a Pediatric Ulcerative Colitis Activity Index of 65 or more points at diagnosis with those in an S0 group defined by an index value below 65. RESULTS Three hundred one children with ulcerative colitis treated at 21 institutions were included, with follow-up for 3.6 ± 1.9 years. Among them, 75 (25.0%) were in S1; their age at diagnosis was 12.3 ± 2.9 years, and 93% had pancolitis. Colectomy free rates in S1 were 89% after 1 year, 79% after 2, and 74% after 5, significantly lower than for S0 (P = 0.0003). Calcineurin inhibitors and biologic agents, respectively, were given to 53% and 56% of S1 patients, significantly more than for S0 patients (P < 0.0001). Among S1 patients treated with calcineurin inhibitors when steroids failed, 23% required neither biologic agents nor colectomy, similarly to the S0 group (P = 0.46). CONCLUSIONS Children with severe ulcerative colitis are likely to require powerful agents such as calcineurin inhibitors and biologic agents; sometimes colectomy ultimately proves necessary. Need for biologic agents in steroid-resistant patients might be reduced to an extent by interposing a therapeutic trial of CI rather than turning to biologic agents or colectomy immediately.

Abstract
BACKGROUND AND AIM Serum leucine-rich alpha-2 glycoprotein (LRG) and calprotectin have been studied as disease activity markers in adults with inflammatory bowel disease (IBD). We evaluated them in pediatric IBD patients. METHODS Subjects under 17 years old undergoing care at 11 Japanese pediatric centers were retrospectively assigned to 3 groups representing Crohn's disease (CD), ulcerative colitis (UC), and normal controls (NC) with irritable bowel syndrome or no illness. Serum LRG and calprotectin were measured using commercial enzyme-linked immunosorbent assay kits. RESULTS We enrolled 173 subjects, including 74 with CD, 77 with UC, and 22 NC. Serum LRG concentrations in active CD (median, 200 μg/mL) were significantly greater than in remission (81 μg/mL; P < 0.001) or NC (69 μg/mL; P < 0.001). Serum calprotectin concentrations in active CD (2941 ng/mL) also were significantly greater than in remission (962 ng/mL; P < 0.05) or NC (872 ng/mL; P < 0.05). Serum LRG concentrations in active UC (134 μg/mL) were significantly greater than in remission (65 μg/mL; P < 0.01) but not significantly greater than in NC (69 μg/mL); serum calprotectin concentrations in active UC (1058 ng/mL) were not significantly different from those in remission (671 ng/mL) or NC (872 ng/mL). In receiver operating characteristic analyses of LRG, calprotectin, C-reactive protein, and erythrocyte sedimentation rate for ability to distinguish active IBD from remission, CD and UC showed areas under receiver operating characteristic curves for LRG (0.77 and 0.70, respectively), exceeding those for calprotectin, C-reactive protein, or erythrocyte sedimentation rate. CONCLUSIONS In pediatric IBD, serum LRG may better reflect disease activity than serum calprotectin, particularly in CD.

Abstract
Inflammatory bowel disease (IBD) is characterized by chronic inflammation of the gastrointestinal tract in chronic or recurrent remission phase and is classified as Crohn's disease (CD) and ulcerative colitis (UC). IBD is a multifactorial disease that results from genetic and environmental factors, immunological disorders, and gut microbiota dysregulation called dysbiosis. Recently, the number of patients with IBD in Japan has been increasing. This review describes studies of T cells such as type 1 helper T (Th1) and type 1 cytotoxic T (Tc1) cells, and cytokines such as IL-17, IL-26 as representatives of mucosal immunity in IBD. It also describes genetic analysis studies on the cause of very early-onset IBD (VEO-IBD). Th1 cells and Tc1 cells are involved in Peyer's patches of CD. IL-12 significantly reduced the production of IL-17 but significantly increased that of IFN-γ, and IL-21 reduced IL-17 production. Furthermore, 11.6% of patients with VEO-IBD presented with monogenic IBD in Japan. Genetic analysis for patients with VEO-IBD and suspected monogenic IBD was investigated. XIAP and heterozygous SLCO2A1 were detected owing to the result of functional confirmation, and several candidate genes were detected. Cytokine analysis and genetic analysis studies have revealed several pathophysiology of IBD. Clinical and basic studies on mucosal immunity, as well as immunological and genetic analyses are currently ongoing, are anticipated to provide an elaborate understanding of the pathophysiology of IBD.

Abstract
Immunosuppressive therapies can affect the immune response to or safety of vaccination in patients with inflammatory bowel disease (IBD). The appropriateness of vaccination should be assessed prior to the initiation of IBD treatment because patients with IBD frequently undergo continuous treatment with immunosuppressive drugs. This consensus was developed to support the decision-making process regarding appropriate vaccination for pediatric and adult patients with IBD and physicians by providing critical information according to the published literature and expert consensus about vaccine-preventable diseases (VPDs) [excluding cervical cancer and coronavirus disease 2019 (COVID-19)] in Japan. This consensus includes 19 important clinical questions (CQs) on the following 4 topics: VPDs (6 CQs), live attenuated vaccines (2 CQs), inactivated vaccines (6 CQs), and vaccination for pregnancy, childbirth, and breastfeeding (5 CQs). These topics and CQs were selected under unified consensus by the members of a committee on intractable diseases with support by a Health and Labour Sciences Research Grant. Physicians should provide necessary information on VPDs to their patients with IBD and carefully manage these patients' IBD if various risk factors for the development or worsening of VPDs are present. This consensus will facilitate informed and shared decision-making in daily IBD clinical practice.

Abstract
BACKGROUND In Japan there are limited opportunities for pediatricians to learn gastrointestinal (GI) endoscopy. This study investigated whether a short-term intensive training for 2 weeks in an adult GI setting enabled pediatricians to acquire basic technical competence for pediatric GI endoscopic procedures. METHODS This was a retrospective case series of pediatricians who underwent 2 weeks of intensive endoscopy training at an adult endoscopy unit in a community hospital. The numbers of esophagogastroduodenoscopy (EGD) and ileocolonoscopy procedures each pediatrician performed were evaluated. All enrolled pediatricians were asked to answer questionnaires regarding the 2 week intensive GI endoscopy training program. RESULTS There were 17 enrolled pediatricians, of whom 13 were men; average age 32 years (range 27-54). The median (range) numbers of EGDs and ileocolonoscopies performed by each pediatrician during the 2-week training period were 102 (66-144) and 14 (1-48), respectively. Fifteen out of 17 pediatricians experienced more than 100 GI endoscopies during the 2 weeks. All pediatricians performed biopsies as part of some EGD procedures. All 17 pediatricians found this program satisfactory. All pediatricians became cable of performing pediatric EGD (i.e., for children ≤15 years) after this training program. Sixteen pediatricians have continued to perform pediatric GI endoscopy since this training program. CONCLUSIONS A short-term intensive training program for 2 weeks in an adult GI setting enabled pediatricians to acquire basic technical competence for pediatric endoscopic procedures.

Abstract
Juvenile polyposis syndrome (JPS) is a rare disease characterized by multiple hamartomatous polyps within the gastrointestinal tract. SMAD4 or BMPR1A is known as a causative gene of JPS. Approximately 75% of newly diagnosed cases have an autosomal-dominantly inherited condition, whereas 25% are sporadic without previous history of polyposis in the family pedigree. Some patients with JPS develop gastrointestinal lesions in childhood and require continuous medical care until adulthood. JPS is classified into three categories according to phenotypic features of polyp distributions, including generalized juvenile polyposis, juvenile polyposis coli, and juvenile polyposis of the stomach. Juvenile polyposis of the stomach is caused by germline pathogenic variants of SMAD4 with a high risk leading to gastric cancer. Pathogenic variants of SMAD4 are also associated with hereditary hemorrhagic telangiectasia-JPS complex, inducing regular cardiovascular survey. Despite growing concerns regarding the managing JPS in Japan, there are no practical guidelines. To address this situation, the guideline committee was organized by the Research Group on Rare and Intractable Diseases granted by the Ministry of Health, Labor and Welfare involving specialists from multiple academic societies. The present clinical guidelines explain the principles in the diagnosis and management of JPS with three clinical questions and corresponding recommendations based on a careful review of the evidence and involve incorporating the concept of the Grading of Recommendations, Assessment, Development, and Evaluation system. Herein, we present the clinical practice guidelines of JPS to promote seamless implementation of accurate diagnosis and appropriate management of pediatric, adolescent, and adult patients with JPS.

Abstract
BACKGROUND In Japan, many asthma inhalers do not have formal approval for use in the pediatric population because of the lack of domestic data. In real-world settings, however, numerous off-label medications are prescribed. Currently, the nature of off-label prescriptions of asthma inhalers on pediatric patients in Japan remains unclear. METHODS Using public open-source national medical claims data, we investigated the real-world descriptive epidemiology of off-label prescriptions for asthma inhalers for pediatric patients. We obtained the number of off-label prescriptions of formulations for patients aged 0-14 years from anonymously summarized prescription data for a 7-year period starting from April 2014. The actual prescription numbers and their chronology over time were then analyzed. RESULTS In 2019, 143,439 asthma inhalers were used off label in children and adolescents. Overall, 96.1% were inhaled corticosteroids (ICSs) or long-acting beta stimulants (LABAs), and 3.9% were high-dose ICS. Of ICSs and LABAs, 18.8% were off-label prescriptions. The total number of off-label ICS/LABA prescriptions and their percentage relative to the overall formulations gradually decreased but a notable disparity was observed among inhaler types. CONCLUSIONS There was a surprisingly large number of off-label prescriptions of asthma inhalers in the pediatric population in Japan. The proper use of ICSs/LABAs and expansion of insurance coverage should be advocated to reduce off-label use.

Abstract
BACKGROUND Reports of zinc and selenium deficiencies accompanying inflammatory bowel disease (IBD) mostly have originated from Western countries and concerned adult patients. Whether Japanese children with IBD have similar deficiencies remained unclear. AIM We aimed to elucidate differences in serum zinc and selenium concentrations in Japanese children between types of IBD. METHODS Children under 17 years old undergoing care at 12 Japanese pediatric centers were retrospectively enrolled between November 2016 and February 2018 to 3 groups representing Crohn's disease (CD), ulcerative colitis (UC), and normal controls (NC) with irritable bowel syndrome or no illnesses. Serum zinc and selenium were measured by atomic absorption spectrophotometry. Zinc and selenium deficiencies were defined by serum concentrations < 70 μg/dL and < 9.5 μg/dL, respectively. RESULTS Subjects included 98 patients with CD (median age, 13 years), 118 with UC (11 years), and 43 NC (11 years). Serum zinc and selenium were significantly lower in CD (median, 64 and 12.6 μg/dL respectively) than in UC (69 and 14.6; P < 0.05 and P < 0.001) or NC (77 and 15.7; P < 0.01 and P < 0.001). Zinc deficiency was significantly more prevalent in CD (60.2%) than in NC (37.2%; P < 0.05), but not than in UC (51.7%; P = 0.22). Selenium deficiency was significantly more prevalent in CD (15.3%) than in UC (5.9%; P < 0.05) or NC (0%; P < 0.01). CONCLUSIONS In Japanese children under 17 years old, serum zinc and selenium were significantly lower in CD than in UC or NC. Zinc and selenium should be monitored, and supplemented when deficient, in children with IBD, especially CD.

Abstract
BACKGROUND The diagnosis of Yersinia enterocolitica (Ye) enteritis is not easy because detection from stool culture is more difficult for Ye than for other bacterial enteritides. The establishment of characteristic ultrasonographic findings for Ye enteritis would help improve the detection rate of Ye enteritis along with performance of several cold cultures. This would facilitate appropriate selection of antibiotics based on antimicrobial susceptibility testing and contribute to a more accurate understanding of local public health. This study aimed to retrospectively compare ultrasonographic findings and clinical features between children with Ye enteritis and other bacterial enteritides. METHODS We identified patients treated for Ye enteritis (Ye group; n = 27) or other bacterial enteritides (Other enteritis group; n = 29) between 2014 and 2018. Ultrasonographic findings (including mean maximum diameter and mean major-minor axis ratio of ileocecal lymph nodes, wall thickness of the terminal ileum, and presence of a pericecal hyperechoic region), clinical symptoms, and laboratory findings at first visit were compared between groups. RESULTS No difference in mean maximum diameter of ileocecal lymph nodes was seen between groups. However, mean major-minor axis ratio of ileocecal lymph nodes was lower in the Ye group than in the Other enteritis group (p < 0.001). Presence of a pericecal hyperechoic region was more frequent in the Ye group than in the Other enteritis group (p < 0.001). The combined presence of a mean ileocecal lymph node major-minor axis ratio <1.51 and a pericecal hyperechoic region offered 100% sensitivity. CONCLUSION Characteristic ultrasonographic findings identified in this study may improve ultrasonographic differentiation of Y. enterocolitica enteritis from other bacterial enteritides.

Abstract
BACKGROUND Noninvasive biomarkers of intestinal inflammation can reduce the number of endoscopies in children with inflammatory bowel disease (IBD). This study aimed to prospectively investigate the usefulness of fecal calprotectin (FCP) and fecal immunochemical test (FIT) in pediatric IBD. METHODS Patients aged 6-17 years who underwent ileocolonoscopy for established or suspected IBD were eligible for this study. Fecal samples for FCP and FIT were collected before colonoscopy. RESULTS A total of 251 samples were analyzed: 88 from ulcerative colitis (UC), 74 from Crohn's disease (CD), 75 from healthy controls (HC), and 14 from children with functional gastrointestinal disorders and normal colonoscopy (NC). At IBD diagnosis, both FCP and FIT were significantly higher in the newly diagnosed UC/CD group than in the HC/NC group (P < 0.001). The optimal cutoffs of FCP and FIT to predict IBD diagnosis were 217 mg/kg and 87 ng/mL, respectively. Patients without mucosal healing (MH) showed higher FCP and FIT than those with MH in both UC and CD (P < 0.001). The FCP increased exponentially as the endoscopic activity score increased. The optimal cutoff values of FCP and FIT for predicting MH were 161 mg/kg and 106 ng/mL for UC and 367 mg/kg and 57 ng/mL for CD, respectively. FCP showed better specificity than the FIT. Patients with CD and normal ileocolonoscopy had elevated FCP during active small intestinal inflammation. CONCLUSIONS Both FCP and FIT correlate well with endoscopic activity in pediatric patients with IBD. The FCP is a superior marker for predicting MH.

Abstract
BACKGROUND AND AIM We retrospectively determined the safety and efficacy of the endoscopic delivery (ED) of capsule endoscopes. METHODS We enrolled 10,156 patients who underwent small bowel capsule endoscopy (SBCE), 3182 who underwent patency capsule (PC), and 1367 who underwent colon capsule endoscopy (CCE), at 11 gastroenterological and nine pediatric centers. RESULTS Small bowel capsule endoscopies, PCs, and CCEs were endoscopically delivered to 546 (5.4%), 214 (6.7%), and 14 (1.0%) patients, respectively. Only mild complications occurred for 21.6% (167/774), including uneventful mucosal damage, bleeding, and abdominal pain. Successful ED of SBCE to the duodenum or jejunum occurred in 91.8% and 90.7% of patients aged <16 years and ≥16 years, respectively (P = 0.6661), but the total enteroscopy rate was higher in the first group (91.7%) than in the second (76.2%, P < 0.0001), for whom impossible ingestion (87.3%) was significantly more common than prolonged lodging in the stomach (64.2%, P = 0.0010). Successful PC and CCE delivery to the duodenum occurred in 84.1% and 28.6%, thereafter the patency confirmation rate and total colonoscopy rate was 100% and 61.5%, respectively. The height, weight, and age cutoff points in predicting spontaneous ingestion were 132 cm, 24.8 kg, and 9 years 2 months, respectively, in patients aged <16 years. Patients aged ≥16 years could not swallow the SBCEs mainly due to dysphagia (75.0%); those who retained it in the esophagus due to cardiac disease (28.6%), etc. and in the stomach due to diabetes mellitus (15.7%), etc. CONCLUSIONS: This large-scale study supports the safety and efficacy of ED in adult and pediatric patients.

Abstract
INTRODUCTION Long-term disease duration of ulcerative colitis (UC) is known to increase the risk of developing colorectal cancer in adults; however, this association has not been genetically analyzed in children with UC. Herein, we examined the expression of cancer-related genes in the colonic mucosa of pediatric UC patients and their risk of developing colorectal cancer. METHODS Microarray analysis of cancer-related gene expression was conducted on rectal mucosa biopsy specimens randomly selected from pediatric cases, including 4 active-phase UC cases, 3 remission-phase UC cases, and 3 irritable bowel syndrome control cases. The subject pool was then expanded to 10 active-phase cases, 10 remission-phase cases, and 10 controls, which were analyzed by real-time polymerase chain reaction (PCR) and immunohistochemical staining. RESULTS The microarray results indicated significantly higher expression levels of cancer-related genes PIM2 and SPI1 in the active group than in the remission and control groups (p < 0.05). Real-time PCR confirmed that PIM2 and SPI1 expression levels were significantly higher, whereas TP53 and APC expression levels were significantly lower, in the active-phase group than in the remission and control groups (p < 0.05). Immunohistochemical staining for PIM2, SPI1, TP53, and APC proteins supported the real-time PCR results. CONCLUSIONS Expression levels of previously unreported cancer-related genes in adult UC patients were significantly higher in pediatric UC patients than in controls. Inflammation of the gastrointestinal mucosa increased the expression levels of cancer-related genes even in childhood-onset UC cases, suggesting that chronic inflammation from childhood may increase the risk of colorectal cancer development.

Abstract
Acute pancreatitis (AP) develops in approximately 2% of patients with the diagnosis of inflammatory bowel disease (IBD), but the characteristics and frequency of childhood-onset IBD-associated AP in Japan have not been studied. The present study aimed to clarify the characteristics of IBD-associated AP in Japan. Methods A nationwide survey of pediatric patients with IBD (age, <17 years) was conducted from December 2012 to March 2013 at 683 hospitals and medical centers in Japan. A secondary survey was also sent to the centers with the target patients to evaluate their characteristics. Results The response rate to the first part of the survey was 61.2% (n = 418). In total, 871 patients with Crohn disease and 1671 patients with ulcerative colitis were enrolled. The second part of the survey found that 11 (1.3%) patients with Crohn disease and 23 (1.4%) patients with ulcerative colitis experienced IBD-associated AP caused by medication (n = 18, 53%), a primary disease (n = 11, 32%), autoimmune pancreatitis (n = 1, 3%), or an anatomical abnormality (n = 1, 3%). All the patients had only mild AP. Conclusions IBD-associated AP was not very frequent and was generally mild. The major cause of the pancreatitis was the medication used to treat the IBD.

Abstract
Inflammatory bowel disease (IBD) is a chronic relapsing inflammatory disorder of the intestine. The incidence of IBD is increasing worldwide, including Japan, and in approximately 25% of all affected patients it is diagnosed before 18 years of age. For the health maintenance of such patients, planned transition to adult care systems is essential. Previous Japanese surveys have revealed gaps between adult and pediatric gastroenterologists with regard to their knowledge and perception of health-care transition for patients with childhood-onset IBD. In 2021-2022, several Web workshops to discuss issues related to the transitional care of IBD patients were held by the Ministry of Health, Labour and Welfare of Japan as part of their program for research on intractable diseases. Clinicians experienced in IBD treatment for pediatric and adult patients participated. As a result, this panel of adult and pediatric gastroenterologists developed five consensus statements on the issue of "transfer from pediatric to adult care" and nine statements on the issue of "addressing transitional care (transition program)." To address current gaps in health-care transition for childhood-onset IBD patients, a programmed approach to transition, and better partnerships between pediatric and adult gastroenterologists are indicated. It is hoped that this consensus statement will provide a basis for the development of appropriate guidelines for clinical practice.

Abstract
BACKGROUND In Japan there are limited opportunities for pediatric gastrointestinal (GI) trainees to learn GI endoscopy. This study investigated whether a short-term intensive training for 3 months in an adult GI unit enabled pediatric GI trainees to acquire the required number of cases and the technical competence to perform pediatric GI endoscopic procedures. METHODS This was a retrospective case series of pediatric GI trainees who underwent 3 months of intensive endoscopy training, which also included direct observation and a questionnaire. The numbers of esophagogastroduodenoscopies (EGD), ileocolonoscopies, and snare polypectomies each trainee performed as well as cecal intubation rates were collected with the goal of meeting the standards of overseas educational guidelines. The trainees were also asked about continuing experience with pediatric endoscopic procedures after the intensive training. RESULTS There were 10 enrolled trainees, 9 men, average age, 34 (range, 29-41). The average number (range) of EGD and ileocolonoscopies that the 10 trainees had done before this training period was 52 (0-200) and 15 (0-20), respectively. The average number (range) of EGD, ileocolonoscopies and snare polypectomies per each trainee was 651.7 (485-814), 159.2 (130-195) and 25.8 (10-55), respectively, over 3 months: all trainees thus fulfilled all of the criteria of the minimal training requirements. All trainees also reached the required threshold in the cecal intubation rate (>90%). In addition, all trainees were able to perform pediatric endoscopic procedures alone after the intensive training period. CONCLUSIONS Short-term intensive training for 3 months in an adult GI setting enabled pediatric GI trainees to acquire technical competence for pediatric endoscopic procedures.

Abstract
BACKGROUND Pediatric ulcerative colitis (UC) is more challenging to treat than adult UC. Qing-Dai therapy is effective in adults but reports of its efficacy in children are unavailable. We conducted a questionnaire survey on Qing-Dai use among pediatric patients with UC in Japan to determine its efficacy and safety. METHODS Questionnaires were sent to 31 high-volume centers treating pediatric patients with inflammatory bowel disease. The number of patients using Qing-Dai, short-term and long-term effects, and adverse events were assessed. A systematic review of studies on the efficacy and safety of Qing-Dai usage for UC was also performed. RESULTS Overall, 29/31 facilities (93.5%) responded, Qing-Dai was used in 107 patients with UC, and 84/107 patients (78.5%) initiated treatment. Within 6 months, 81/101 (80.2%) patients had clinical remission, while 59/92 (64.1%) patients had no relapse and 29/92 (31.5%) experienced only one to two relapses yearly. Eighty-seven percent of the patients underwent regular follow ups for adverse events, among whom one patient was diagnosed with pulmonary arterial hypertension (PAH), five with enteritis, and one with headache. In the systematic review, the clinical remission rate was 50-80%, and PAH was observed in 14 of 1,158 patients (1.2%). CONCLUSIONS Qing-Dai is highly effective in treating pediatric UC. However, Qing-Dai should be administered with caution as it may cause adverse events such as PAH.

Abstract
BACKGROUND Inclusion of female authors has been noted as potentially beneficial in the development of medical guidelines. Japanese professional committees representing allergic subspecialties develop practical guidelines with recommendations to caregivers, but these committees may be influenced by their gender composition. The objective of our study was to examine the influence of gender in developing pediatric allergic disease guidelines in Japan from 1999 to 2020. METHODS We examined the gender parities among the guideline committee members in allergic rhinitis, atopic dermatitis, bronchial asthma, and food allergy guidelines in Japan. We examined the gender composition of the committees, annual trends, and differences in guideline content. RESULTS The median proportion of women members among the 22 guidelines committees was 6.6% (range: 0%-27.3%). The analysis of the quadrant period did not show a significant increase in the proportion of female members. The food allergy group had a significantly higher proportion of female members than other guidelines (P < 0.01), but the proportion decreased from 25% to 14.3% during the observation period. For the pediatric asthma guidelines, the proportion of female committee members decreased from 5.3% in the 2000 version to 0% in the most recent revision in 2017. CONCLUSIONS The proportion of women on the committees that develop pediatric guidelines continues to be low and has not improved over the past 20 years.

Abstract
Abstract
Background
Granulomatosis with polyangiitis (GPA) is a syndrome of refractory vasculitis involving the upper respiratory tract, lungs, kidneys, and systemic small and medium-sized arteries that affects all age groups. No pediatric case with a bloody pericardial effusion resulting in cardiac tamponade and co-existing hematochezia has been reported.
Case presentation
A 14-year-old boy was referred for evaluation of prolonged fever, chest pain, and intermittent hematochezia. Diagnostic imaging showed a prominent pericardial effusion. Immediately after admission, his systolic blood pressure decreased. Emergent pericardiocentesis resulted in aspiration of a massive amount of bloody pericardial fluid. This was diagnosed as cardiac tamponade because his blood pressure recovered immediately after the drainage. The patient had an elevated serine proteinase 3-anti-neutrophil cytoplasmic antibody (PR3-ANCA) level on serological examination. Head MRI showed thickening of nasal and sinusoidal mucosa and a cystic mass in the left sphenoid sinus. After ruling out malignancy based on the cytology of the effusion, chest MRI, and gallium scintigraphy, total colonoscopy showed multiple irregular-shaped aphthae from the right transverse colon to the cecum on the contralateral side of the mesenteric attachments. Biopsy specimens of aphthous lesions confirmed necrotizing granulomatous inflammation. A diagnosis of GPA was made based on these findings, and oral prednisolone (PSL) and azathioprine were started. The hematochezia disappeared rapidly, and no recurrence of pericardial effusion was seen after PSL tapering was completed. The PR3-ANCA level decreased into the normal range immediately after the initial therapy.
Conclusions
Pericarditis is a common cardiac complication of GPA, but there have been no reports of resultant cardiac tamponade. This is the first case of pediatric GPA with cardiac and gastrointestinal complications preceding the common symptoms such as respiratory or renal symptoms. A case of pediatric GPA with hematochezia is also extremely rare. In conclusion, serial measurement of ANCA levels is important in patients with persistent fever and bloody stool, such as in inflammatory bowel disease, to make the diagnosis of a vasculitic syndrome.

Abstract
BACKGROUND The Epstein-Barr virus (EBV) infection status in patients with inflammatory bowel disease (IBD), particularly those using thiopurines, may be associated with the risk of lymphoproliferative disorder and hemophagocytic lymphohistiocytosis. This was the first multicenter survey of EBV infection in Japanese patients with IBD. Factors related to the EBV infection status were also investigated. METHODS Five tertiary institutions in Japan participated in this study to examine pediatric and adult patients with IBD. Serum EBV anti-viral capsid antigen (VCA) IgG, EBV anti-VCA IgM, and anti-EBV nuclear antigen-antibody were measured in 495 patients with IBD. The patients' information was obtained from their medical records. Prior EBV infection was defined as anti-VCA IgM negativity and anti-VCA IgG positivity (UMIN000033004). RESULTS The patients' median age was 25 years (range 0-92 years). Of the 495 patients, nine were anti-VCA IgM-positive and 354 were anti-VCA IgG-positive (seroprevalence: 72.8%). The proportion of patients with prior EBV infection was 0% for those aged < 5 years, < 60% for those aged < 30 years, and > 90% for those aged > 30 years. The proportion of EBV-uninfected patients using thiopurines was 28.4% (52/183) for all patients and 51.8% (44/85) for pediatric patients. Age was significantly associated with anti-VCA IgG seropositivity (p < 0.01, odds ratio: 0.902, 95% confidence interval: 0.880-0.925). No cases of lymphoproliferative disorder, hemophagocytic lymphohistiocytosis, or chronic active EBV infection were reported. CONCLUSIONS Approximately 30% of Japanese patients with IBD were EBV-uninfected, including those using thiopurines. Age was a significant factor for anti-VCA IgG seropositivity.

Abstract
Background and Aim We aimed to evaluate endoscopic findings of Helicobacter pylori (H. pylori)-positive children and young adults based on the Kyoto classification, and to examine if there are age-associated changes in H. pylori-positive gastritis. Methods H. pylori-positive patients under 40 years old who underwent upper gastrointestinal endoscopy from 1 April 2009 to 15 February 2017 were included. Subjects were classified into the Pediatric (<20 years) and Young adult groups (20-39 years). The patients' endoscopic photographs were retrospectively re-evaluated based on the Kyoto classification. We compared endoscopic findings between the two groups and examined alterations in the findings of H. pylori-associated gastritis in 5-year age groups. Results Forty-three and 163 subjects were classified into the Pediatric and Young adult groups, respectively. In the Pediatric group, nodularity was seen in the majority (93.0%); other endoscopic findings in order of decreasing frequency included mucosal swelling (32.6%), spotty redness (25.6%), diffuse redness (18.6%), and atrophy (9.3%). In the Young adult group, endoscopic findings included atrophy (66.9%), mucosal swelling (49.7%), spotty redness (39.3%), nodularity (31.9%), and diffuse redness (30.3%). The difference in prevalence of nodularity or atrophy between the two groups reached statistical significance (P < 0.0001 each). The rate of nodularity decreased with increasing age in the Young adult group. The rate of atrophy was 33% in young adult patients aged 20-24, and the rate increased to >65% in patients over age 25. Conclusion H. pylori-positive children had endoscopic findings besides nodularity based on the Kyoto classification. The prevalence of atrophy increased in patients over age 20.

Abstract
INTRODUCTION Anal fistulae have a significant impact on the quality of life of patients with Crohn's disease (CD). In this cross-sectional study, we aimed to determine whether biological agents were effective in treating anal fistulae in patients with CD. METHODS Fifty-three patients diagnosed with CD were retrospectively enrolled. Their data regarding symptoms, treatments, and disease progression from January 2007 to December 2016 were reviewed from the medical records. Fifteen (28%) patients with CD were complicated by anal fistulae. RESULTS The male-to-female ratio was 13:2, and the mean age at onset was 11 years and 6 months. Among the 15 patients, 14 (93%) had anal fistulae as an initial symptom. Almost all patients were treated by providing elemental diet, 5-aminosalicylic acid, and steroids as induction therapy. Biological agents were used in 8 patients (53.3%), and fistula closure was confirmed in all of them. Among the 7 patients not treated with biological agents, 1 (14.3%) had a recurrent anal fistula, while another had incomplete fistula closure. Regarding surgical management, 2 patients were treated using the seton method, and no patients required a colostomy. CONCLUSION Treatment with biological agents is highly effective concerning the closure of anal fistulae in patients with CD, and reducing pain may improve their quality of life.

Abstract
INTRODUCTION The incidence of early-onset inflammatory bowel disease is increasing in Japan. OBJECTIVE This study aimed to analyze the treatment and progress of early-onset inflammatory bowel disease. METHODS This prospective survey evaluated the data of 43 patients aged <8 years who were diagnosed with inflammatory bowel disease (IBD) from the time of diagnosis to 36 months after registration. RESULTS A total of 12 patients with Crohn's disease (CD), 21 with ulcerative colitis (UC), and 3 with unclassified IBD were enrolled. The mean disease onset age was 3 years and 7 months. Colon and anal lesions were present in 100 and 50% of patients with CD, respectively. Granulomas were detected in 5 patients (41.7%). Dietary elimination including elemental diet was performed in all patients. Eleven patients (91.7%) were in remission by initial induction therapy, and 72.7% maintained remission for 36 months. Three patients (14.3%) with UC had familial history, 71.4% had pancolitis-type UC, and 66.7% exhibited disease of moderate severity. Colectomy was performed in 4 patients (21.1%). Eighteen patients (85.7%) were in remission by initial induction therapy; however, only 15.8% maintained remission for 36 months. Anal complication was more prevalent in infantile-onset IBD than in childhood-onset IBD (p = 0.014). CONCLUSIONS Among Japanese patients aged <8 years who were diagnosed with IBD, colitis-type disease was more common in CD and pancolitis was more common in UC. As the courses of several patients were severe, identifying primary immunodeficiency appears to be necessary to confirm background disease.

Abstract
BACKGROUND AND AIM The implementation rates of pediatric gastrointestinal endoscopy are increasing with advancements in the devices used and pediatricians' skills. As part of the Japan Pediatric Endoscopy Study Group, we aimed to investigate the rates of pediatric gastrointestinal endoscopy use and the associated adverse events through a nationwide survey. METHODS A questionnaire was sent to 630 institutions in Japan. The numbers of pediatric gastrointestinal endoscopy cases and adverse events occurring during endoscopy, from April 2011 to March 2016, were investigated. RESULTS Responses were obtained from 445 facilities. The total number of pediatric gastrointestinal endoscopies was 37 447 and that of endoscopic examinations was 32 219 (86.0%), with esophagogastroduodenoscopy accounting for 18 484 cases; ileal colonoscopy, 11 936; endoscopic retrograde cholangiopancreatography, 389; wireless capsule endoscopy, 897; and balloon-assisted enteroscopy, 513. The number of endoscopic treatments was 5228, followed by balloon dilatation (1703), foreign body removal (989), and polypectomy (822); 201 adverse events (0.54%) occurred, 79 of which presented during endoscopic examination (0.25%). Eight serious perforations were noted in 0.0054% and 0.025% of those undergoing esophagogastroduodenoscopy and colonoscopy, respectively. Overall, 122 adverse events (2.33%) occurred in association with endoscopic treatment. One case of cardiopulmonary arrest occurred because of accidental extubation. However, no deaths occurred. CONCLUSION Endoscopic examinations had a slightly higher adverse event rate, because of an increase in endoscopic retrograde cholangiopancreatography and small intestine enteroscopy, than that reported in previous studies, but the adverse event rate of endoscopic treatment did not increase.

Abstract
BACKGROUND AND AIM Serologic markers such as myeloperoxidase (MPO) antineutrophil cytoplasmic antibodies (ANCA) (MPO-ANCA) have been used to screen patients for ulcerative colitis (UC). However, MPO-ANCA shows limited accuracy in Asians. Proteinase 3 ANCA (PR3-ANCA) has performed better at UC diagnosis in Japanese adults than MPO-ANCA. The present study aimed to evaluate usefulness of PR3-ANCA for diagnosis of UC in Japanese pediatric practice. METHODS Patients under 17 years old undergoing assessment at 12 Japanese pediatric centers between November 2016 and February 2018 were prospectively enrolled and divided into groups with UC, Crohn's disease (CD), intestinal disease control (IC), and healthy control (HC). Serum PR3-ANCA and MPO-ANCA were analyzed using chemiluminescence enzyme immunoassay kits. RESULTS Sera from 367 patients (148 with UC at a median age of 12 years; 120 with CD, 13 years; 56 with IC, 10.5 years; and 43 with HC, 10 years) were examined. Median PR3-ANCA values in UC (1.6 U/mL) were greater than in CD (0.2; P < 0.001), IC (0.15; P < 0.001), and HC (0.1; P < 0.001). In receiver operating characteristic curve analyses, the area under the curve for PR3-ANCA was 0.79, significantly greater than for MPO-ANCA (0.58; P < 0.001). Using a cut-off value of 0.8 U/mL determined from the receiver operating characteristic analyses, PR3-ANCA showed significantly greater sensitivity (64.9%) than MPO-ANCA (cut-off, 0.2 U/mL; sensitivity, 19.6%; P < 0.001) and good specificity (83.6%). CONCLUSIONS In Japanese children and adolescents, PR3-ANCA performed better as a serologic marker for diagnosis of UC than MPO-ANCA. To our knowledge, this is the first report of such a comparison.

Abstract
AIM Linked colour imaging is an image-enhanced endoscopy system that emphasizes the red portion of the mucosa's colour. Our aim was to compare the effectiveness of linked colour imaging with white-light colonoscopy for the detection of flat-type colorectal polyps. METHOD This was a single-centre, randomized controlled trial. Enrolled patients were those aged ≥50 years undergoing cap-assisted colonoscopy for colorectal cancer screening. They were randomized in a 1:1 ratio for observation using linked colour imaging or white-light colonoscopy. All colorectal polyps detected were removed or biopsied. The primary outcome was the number of flat-type polyps per patient in patients in whom flat polyps were detected. Secondary outcomes included adenoma and polyp detection rates. RESULTS There were 302 subjects randomized: 152 to linked colour imaging and 150 to white-light colonoscopy. There were no differences in the clinical features between the two arms. The number of flat polyps detected per patient using linked colour imaging was approximately twice that with white light (2.9 ± 3.0 vs 1.2 ± 1.6, p = 0.045). Linked colour imaging also proved superior to white-light colonoscopy in terms of adenoma and polyp detection rates [adenomas 66% (101/152) vs 49% (73/150), p = 0.0024; polyps 69% (105/152) vs 55% (82/150), p = 0.013]. The ratio of polyps detected in the right colon compared with those detected in the left colon was significantly greater using linked colour than white-light imaging (168/64 vs 93/84; p < 0.001). CONCLUSION Compared with white-light colonoscopy, linked colour imaging improved adenoma and polyp detection rates, including detection of flat-type colorectal polyps.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection causes chronic gastritis, duodenal and to a lesser extent, gastric ulcers, and gastric cancer. Most H. pylori infections are acquired in childhood, and effective treatment of childhood infection is very important. Esophagogastroduodenoscopy (EGD) is useful for endoscopic diagnosis, mucosal tissue biopsy, and culture examination for H. pylori in children and adults. In this paper, we report results of susceptibility tests and eradication rates in H. pylori-positive children who underwent EGD over a 12-year period. MATERIALS AND METHODS The subjects were H. pylori-positive pediatric patients who had gastrointestinal symptoms and underwent EGD in the Department of Pediatrics, Juntendo University Hospital (January 2007-December 2018). Patients underwent serum IgG antibody tests, fecal antigen tests, or urea breath tests, and subsequently, culture tests by gastric mucosal biopsy during EGD. H. pylori positivity was defined as a positive result on both tests. Patients received triple therapy for 14 days using our regimen, and eradication was assessed at 2, 6, and 12 months after therapy. RESULTS Forty-five patients were H. pylori-positive, and the overall clarithromycin (CAM) resistance rate was 71.1 % (32/45). The CAM resistance rate for the 2013-2018 period was significantly higher than the 2007-2012 period (52.6% vs. 84.6%, P < 0.05). According to the results of the antimicrobial susceptibility test, we prescribed effective antibiotics, and this resulted in a primary eradication rate of 97.7%. CONCLUSIONS We suggest that antimicrobial susceptibility testing can significantly improve rates of primary eradication of H. pylori infection.

Abstract
BACKGROUND AND AIM Very early-onset inflammatory bowel disease is defined as inflammatory bowel disease diagnosed before 6 years of age. Very early-onset inflammatory bowel disease has various differential diagnoses, including primary immunodeficiency disorders, and is known to be resistant to conventional treatment. Therefore, global attention is required to manage this challenging condition. We conducted a retrospective epidemiological survey of the number of patients, final diagnosis, and examinations performed to diagnose very early-onset inflammatory bowel disease in Japan. METHODS A primary questionnaire about the number of very early-onset bowel disease cases and its diagnosis was administered to 630 pediatric facilities nationwide in Japan. A secondary survey about the examinations performed to achieve diagnosis was sent to the facilities that responded to the first survey. RESULTS The answering rate was 92.2% (581/630 facilities); 81 facilities had 225 very early-onset bowel disease patients undergoing their care during the past 68 months. Twenty-six patients (11.6%) were diagnosed with immunodeficiency-associated inflammatory bowel disease. The answering rate of the secondary survey was 70.4% (57/81 facilities). Colonoscopy, esophagogastroduodenoscopy, and small bowel imaging were performed for 99.4%, 67.5%, and 28.8% of patients, respectively. Genetic analysis was performed for 26.9% (43/160 patients) of patients, and 51.2% (22/43) of patients were diagnosed with immunodeficiency-associated inflammatory bowel disease. CONCLUSIONS Approximately 40 patients are diagnosed yearly in Japan. Imaging studies, especially for small bowel lesions, can be challenging for this unique group of patients. However, a comprehensive approach including immunological and genetic analyses appears useful for diagnosing immunodeficiency-associated inflammatory bowel disease.

Abstract
BACKGROUND In 2019 we reported the results of a Japanese national survey designed to explore the views of adult gastroenterologists regarding transitional care for patients with childhood-onset inflammatory bowel disease (IBD). For the present study, we conducted a similar survey of pediatric gastroenterologists to compare the views of the two sets of specialists. METHODS The survey conducted in 2019 involved 48 representative members of the Japanese Society for Pediatric Gastroenterology, Hepatology and Nutrition. They were contacted by conventional mail and their answers were not anonymized. Respondents who had already referred patients with IBD to adult gastroenterologists were asked in a questionnaire to rank the importance of specific statements on a Likert scale. RESULTS The response rate was 79% and 29 (60%) of the respondents had experienced transitional care for patients with IBD. Transfer to adult care was considered by 90% of the respondents to be the ideal form of medical care for adolescents/young adults with IBD. However, 59% of the respondents had experienced some degree of difficulty when making referrals for such care. The majority of pediatric gastroenterologists considered that the ideal age for transfer was 18-22 years. Among the respondents, physicians at municipal hospitals considered that the presence of diseases other than IBD and a shortage of manpower were significantly more important issues than other practice settings. CONCLUSIONS The present survey revealed that the general views regarding transitional care for IBD between pediatric and adult gastroenterologists were similar, except for the appropriate time for transfer. The results underline the importance of preparing a transition program appropriate to practice settings.

Abstract
Mesenchymal cells in the crypt play indispensable roles in the maintenance of intestinal epithelial homeostasis through their contribution to the preservation of stem cells. However, the acquisition properties of the production of stem cell niche factors by the mesenchymal cells have not been well elucidated, due to technical limitations regarding the isolation and subsequent molecular and cellular analyses of cryptal mesenchymal cells. To evaluate the function of mesenchymal cells located at the large intestinal crypt, we established a novel method through which cells are harvested according to the histologic layers of mouse colon, and we compared cellular properties between microenvironmental niches, the luminal mucosa and crypts. The gene expression pattern in the cryptal mesenchymal cells showed that receptors of the hormone/cytokine leptin were highly expressed, and we found a decrease in Wnt2b expression under conditions of leptin receptor deficiency, which also induced a delay in cryptal epithelial proliferation. Our novel stratified layer isolation strategies thus revealed new microenvironmental characteristics of colonic mesenchymal cells, including the intrinsic involvement of leptin in the control of mucosal homeostasis.
