    Background: There is a lack of predictive biomarkers for the onset or activity of protein-losing enteropathy (PLE), a Fontan procedure-associated complication. Here, we aimed to identify the gut microbiota composition of patients with active PLE and investigate its relationship with PLE activity. Methods: This multicenter case–control study involved patients who developed PLE (n = 16) after the Fontan procedure and those who did not (non-PLE; n = 20). Patients with PLE who maintained a serum albumin level of ≥3 g/dL for >1 year were included in the remissive-stage-PLE group (n = 9) and those who did not maintain this level were included in the active-PLE group (n = 7). 16S rRNA gene sequencing analysis of fecal samples was performed using QIIME2 pipeline. Alpha (Shannon and Faith's phylogenetic diversity indices) and beta diversity was assessed using principal coordinate analysis based on unweighted UniFrac distances. Results: Shannon and Faith's phylogenetic diversity indices were lower in the active-PLE group than in the remissive-stage- (q = 0.028 and 0.025, respectively) and non-PLE (q = 0.028 and 0.017, respectively) groups. Analysis of beta diversity revealed a difference in the microbiota composition between the active-PLE and the other two groups. Linear discriminant effect size analysis demonstrated differences in the relative abundance of Bifidobacterium and Granulicatella spp., and Ruminococcus torques between patients with active- and those with remissive-stage-PLE. Conclusions: Gut microbiota dysbiosis was observed in patients with active PLE. Changes in the bacterial composition of the gut microbiota and decreased diversity may be associated with the severity of PLE.

    Background: In limited resource settings, identification of factors that predict the occurrence of pulmonary hypertension(PH) in children with atrial septal defect(ASD) is important to decide which patients should be prioritized for defect closure to prevent complication. Echocardiography and cardiac catheterization are not widely available in such settings. No scoring system has been proposed to predict PH among children with ASD. We aimed to develop a PH prediction score using electrocardiography parameters for children with ASD in Indonesia. Methods: A cross-sectional study reviewing medical record including ECG record was conducted among all children with newly diagnosed isolated ASD admitted to Dr Sardjito Hospital in Yogyakarta, Indonesia during 2016–2018. Diagnosis of ASD and PH was confirmed through echocardiography and/or cardiac catheterization. Spiegelhalter Knill-Jones approach was used to develop PH prediction score. Accuracy of prediction score was performed using a receiver operating characteristic (ROC) curve. Results: Of 144 children, 50(34.7%) had PH. Predictors of pulmonary hypertension were QRS axis ≥120°, P wave ≥ 3 mm at lead II, R without S at V1, Q wave at V1, right bundle branch block (RBBB), R wave at V1, V2 or aVR > normal limit and S wave at V6 or lead I > normal limit. ROC curve from prediction scores yielded an area under the curve (AUC) 0.908(95% CI 0.85–0.96). Using the cut-off value 3.5, this PH prediction score had sensitivity of 76%(61.8–86.9), specificity 96.8%(91.0-99.3), positive predictive value 92.7%(80.5–97.5), negative predictive value 88.4%(82.2–92.6), and positive likelihood ratio 23.8(7.7–73.3). Conclusions: A presence of PH in children with ASD can be predicted by the simple electrocardiographic score including QRS axis ≥120°, P wave ≥3 mm at lead II, R without S at V1, Q wave at V1, RBBB, R wave at V1, V2 or aVR > normal limit and S wave at V6 or lead I > normal limit. A total score ≥ 3.5 shows a moderate sensitivity and high specificity to predict PH among children with ASD.

    Background Coronary arterial aneurysms (CAAs) associated with Kawasaki disease (KD) significantly affect prognosis. However, the clinical course of CAAs and factors associated with CAA regression have not been well analyzed. Methods and Results The cohort of the Z-Score 2nd Project Stage study, a multicenter, retrospective, cohort study involving 44 institutions in Japan including 1006 patients with KD, was examined. CAAs were classified by the z score of their internal diameter in the acute phase: small (z<5), medium (5≤z<10), and large (z≥10). The lower limit of small CAA was based on the Japanese Ministry of Health, Labour and Welfare criteria. In the right coronary artery, the CAA regression rates 10 years after diagnosis were 95.5% for small, 83.2% for medium, and 36.3% for large. In the proximal left anterior descending artery, the regression rates 10 years after diagnosis were 95.3% for small, 80.1% for medium, and 28.8% for large. Cox regression analysis showed that diagnosis under the age of 1 year and onset of KD in 2010 to 2012 for the right coronary artery and the left anterior descending artery, and female for the right coronary artery were significantly associated with a high regression rate, whereas large CAAs for the right coronary artery and the left anterior descending artery were significantly associated with a low regression rate. Conclusions The current study, the largest Japanese study of its kind, found that small aneurysm, recent onset, and diagnosis under the age of 1 year predict regression, and that even giant aneurysms could regress. These data may contribute to long-term management of coronary aneurysms. Registration URL: https://www.umin.ac.jp/ctr/; Unique identifier: UMIN000010606.

    Research question: What is the proportion of infants born as a result of assisted reproductive technology ART across different types of neonatal critical congenital heart disease (CCHD) in a Japanese population? Design: A retrospective analysis of 418 consecutive infants with CCHD that required catheter treatment or surgery within the first 28 days of life or ductal-dependent lesions, in two paediatric centres in Japan, between January 2014 and December 2019. The proportion of ART in infants with each type of CCHD was evaluated. The proportion of ART in infants with univentricular heart defect (UVH) compared with those with biventricular heart defect (BVH) was evaluated. Results: The study group included 229 boys and 189 girls, with a gestational age of 38 ± 2 weeks. Overall, 61 infants (14.6%) were conceived by fertility treatment with 46 (11.0%) conceived by ART. Univentricular heart defect and BVH were identified in 111 infants (26.6%) and 307 infants (73.4%), respectively. The proportion of infants conceived by ART was significantly higher in UVH (16.2%) than in BVH (9.1%) (OR 2.28, 95% CI 1.11 to 4.68, P = 0.025), regardless of maternal age and maternal history of miscarriage. Conclusions: The proportion of ART in infants with CCHD, especially UVH, was high. These findings could form the basis of a rationale for carrying out fetal echocardiography in fetuses conceived by ART.

    <p><b><i>Background:</i></b>The usefulness of electrocardiographic (ECG) voltage criteria for diagnosing hypertrophic cardiomyopathy (HCM) in pediatric patients is poorly defined.</p><p><b><i>Methods and Results:</i></b>ECGs at the 1st grade (mean [±SD] age 6.6±0.3 years) were available for 11 patients diagnosed with HCM at around the 7th grade (13.2±0.3 years). ECGs were available for another 64 patients diagnosed with HCM in the 1st (n=15), 7th (n=32), and 10th (n=17) grades. Fifty-one voltage criteria were developed by grade and sex using 62,841 ECGs from the general population. Voltage criteria were set at the 99.95th percentile (1/2,000) point based on the estimated prevalence of childhood HCM (2.9 per 100,000 [1/34,483]) to decrease false negatives. Conventional criteria were from guidelines for school-aged children in Japan. Of 11 patients before diagnosis, 2 satisfied conventional criteria in 1st grade; 5 (56%) of the remaining 9 patients fulfilled 2 voltage criteria (R wave in limb-lead I [RI]+S wave in lead V3 [SV3] and R wave in lead V3 [RV3]+SV3). Robustness analysis for sensitivity showed RV3+SV3 was superior to RI+SV3. For all patients after diagnosis, RI+SV4 was the main candidate. However, conventional criteria were more useful than voltage criteria.</p><p><b><i>Conclusions:</i></b>Early HCM prediction was possible using RV3+SV3 in >50% of patients in 1st grade. Voltage criteria may help diagnose prediagnostic or early HCM, and prevent tragic accidents, although further prospective studies are required.</p>

    Background: Tenascin-C (TN-C) is an extracellular matrix glycoprotein related to tissue inflammation. Our previous retrospective study conducted in 2016 revealed that the serum tenascin-C level was higher in patients with Kawasaki disease (KD) who were resistant to intravenous immunoglobulin (IVIG) and developed coronary artery lesions (CALs). The present study is a prospective cohort study to assess if the serum level of tenascin-C could be used as a novel biomarker to predict the risk of resistance to initial treatment for high-risk patients. Methods: A total of 380 KD patients were registered and provided serum samples for tenascin-C measurement before commencing their initial treatment. Patients who did not meet the inclusion criteria were excluded from analysis; of the 181 remaining subjects, there were 144 low-risk patients (Kobayashi score: ≤4 points) and 37 high-risk patients (Kobayashi score: ≥5 points). The initial treatments for low-risk patients and high-risk patients were conventional therapy (IVIG with aspirin) and prednisolone combination therapy, respectively. The patient clinical and laboratory data, including the serum tenascin-C level, were compared between initial treatment responders and non-responders. Results: In the low-risk patients, there was no significant difference in the median levels of serum tenascin-C between the initial therapy responders and non-responders. However, in the high-risk patients, the median serum tenascin-C level in initial therapy non-responders was significantly higher than that in initial therapy responders (175.8 ng/ml vs 117.6 ng/ml). Conclusions: Serum tenascin-C could be a biomarker for predicting the risk of high-risk patients being non-responsive to steroid combination therapy. Trial registration: This study was a prospective cohort study. It was approved by the ethics committee of each institute and performed in accordance with the Declaration of Helsinki.

    BACKGROUND: A gain-of-function mutation in germline ABL1 causes a syndrome including congenital heart defects. However, the molecular mechanisms of this syndrome remain unknown. In this study, we found a novel ABL1 mutation in a Japanese family with ventricular septal defect, finger contracture, skin abnormalities and failure to thrive, and the molecular mechanisms of these phenotypes were investigated. METHODS AND RESULTS: Whole-exome sequencing on several family members revealed a novel mutation (c.1522A > C, p.I508L) in the tyrosine kinase domain of ABL1, and complete co-segregation with clinical presentations was confirmed in all members. Wild-type and mutant ABL1 were transfected into human embryonic kidney 293 cells for functional analysis. Western blotting confirmed that tyrosine phosphorylation in STAT5, a substrate of ABL1, was enhanced, and the novel mutation was proved to be a gain-of-function mutation. Since this novel mutation in ABL1 enhances tyrosine kinase activity, phosphorylated proteome analysis was used to elucidate the molecular pathology. The proteome analysis showed that phosphorylation in proteins such as UFD1, AXIN1, ATRX, which may be involved in the phenotypes, was enhanced in the mutant group. CONCLUSIONS: The onset of congenital heart defects associated with this syndrome appears to involve a mechanism caused by UFD1 common to 22q.11.2 deletion syndrome. On the other hand, AXIN1 and ATRX may be important in elucidating the mechanisms of other phenotypes, such as finger contracture and failure to thrive. Verification of these hypotheses would lead to further understanding of the pathophysiology and the development of treatment methods.

    The aim of this study was to investigate whether a dual endothelin receptor antagonist bosentan modulates the kinetics of bone marrow-derived stem cells in inhibiting the development of pulmonary hypertension. Bone marrow chimeric mice, transplanted with enhanced green fluorescent protein (eGFP)-positive bone marrow mononuclear cells, were exposed to hypobaric hypoxia or kept in the ambient air, and were daily treated with bosentan sodium salt or saline for 21 days. After the treatment period, right ventricular pressure was measured and pulmonary vascular morphometry was conducted. Incorporation of bone marrow-derived cells was analyzed by immunohistochemistry. Gene expression and protein level in the lung tissue were evaluated by quantitative real-time PCR and western blotting, respectively. The results showed that, in hypoxic mice, right ventricular pressure and the percentage of muscularized vessel were increased and pulmonary vascular density was decreased, each of which was reversed by bosentan. Bone marrow-derived endothelial cells and macrophages in lungs were increased by hypoxia. Bosentan promoted bone marrow-derived endothelial cell incorporation but inhibited macrophage infiltration into lungs. Quantitative real-time PCR analysis revealed that interleukin 6, stromal cell-derived factor-1, and monocyte chemoattractant protein-1 were upregulated by hypoxia, in which interleukin 6 and monocyte chemoattractant protein-1 were downregulated and stromal cell-derived factor-1 was upregulated by bosentan. Protein level of endothelial nitric oxide synthase (eNOS) in the whole lung was significantly upregulated by hypoxia, which was further upregulated by bosentan. Bosentan modulated kinetics of bone marrow-derived ECs and macrophages and related gene expression in lungs in ameliorating pulmonary hypertension in mice. Altered kinetics of bone marrow-derived stem cells may be a novel mechanism of the endothelin receptor blockade in vivo and confer a new understanding of the therapeutic basis for pulmonary hypertension.

    Dysregulated bone morphogenetic protein (BMP) signaling in endothelial cells (ECs) is implicated in vascular diseases such as pulmonary arterial hypertension (PAH). Here, we showed that the transcription factor ATOH8 was a direct target of SMAD1/5 and was induced in a manner dependent on BMP but independent of Notch, another critical signaling pathway in ECs. In zebrafish and mice, inactivation of <italic>Atoh8</italic> did not cause an arteriovenous malformation–like phenotype, which may arise because of dysregulated Notch signaling. In contrast, <italic>Atoh8-</italic>deficient mice exhibited a phenotype mimicking PAH, which included increased pulmonary arterial pressure and right ventricular hypertrophy. Moreover, <italic>ATOH8</italic> expression was decreased in PAH patient lungs. We showed that in cells, ATOH8 interacted with hypoxia-inducible factor 2α (HIF-2α) and decreased its abundance, leading to reduced induction of HIF-2α target genes in response to hypoxia. Together, these findings suggest that the BMP receptor type II/ALK-1/SMAD/ATOH8 axis may attenuate hypoxic responses in ECs in the pulmonary circulation and may help prevent the development of PAH.

    ORAI1 encodes a calcium channel essential in the store-operated calcium entry mechanism. A previous genetic association study identified a rare in-frame insertion variant of ORAI1 conferring Kawasaki disease (KD). To deepen our understanding of the involvement of rare variants of ORAI1 in KD pathogenesis, we investigated 3812 patients with KD and 2644 healthy individuals for variations in the protein-coding region of ORAI1. By re-sequencing the study participants’ DNA, 27 variants with minor allele frequencies (MAFs) < 0.01 that had not been examined in the previous study were identified. Although no significant association with KD was observed either in single-variant analyses or in a collapsing method analysis of the 27 variants, stratification by MAFs, variant types, and predicted deleteriousness revealed that six rare, deleterious, missense variants (MAF < 0.001, CADD C-score ≥ 20) were exclusively present in KD patients, including three refractory cases (OR = ∞, P = 0.046). The six missense variants include p.Gly98Asp, which has been demonstrated to result in gain of function leading to constitutive Ca2+ entry. Conversely, five types of frameshift variants, all identified near the N terminus and assumed to disrupt ORAI1 function, showed an opposite trend of association (OR = 0.35, P = 0.24). These findings support our hypothesis that genetic variations causing the upregulation of the Ca2+/NFAT pathway confer susceptibility to KD. Our findings also provide insights into the usefulness of stratifying the variants based on their MAFs and on the direction of the effects on protein function when conducting association studies using the gene-based collapsing method.

    <p><b>Background</b>: The number of patients with trisomy 18 undergoing cardiac surgery has recently been increasing. In our institute, the primary purpose of treatment in patients with trisomy 18 is to facilitate discharge and cardiac surgery has not yet been performed in such cases. In the present report, we reviewed patients treated at our institute to demonstrate the prognosis of patients with trisomy 18 without cardiac surgery.</p><p><b>Methods</b>: We collected detailed clinical information from the medical records of 17 patients with trisomy 18 from April 2005 to December 2015. We retrospectively studied the neonatal condition, survival rate, and cause of death. We also reviewed patients with a high pulmonary flow, the large left-to-right shunt (LS) group, who were at a potential risk of heart failure.</p><p><b>Results</b>: All patients had congenital heart disease (CHD). The 1-year survival rate was 64.7%, with 70.6% of patients discharged at a median age of 129 days (range, 16–285 days). The median survival time of patients who died during the present study was 104.5 days (range, 0–1,054 days). In the LS group, 62.5% of patients survived for one year with no evidence of heart failure. Two patients in the LS group died in hospital from heart failure.</p><p><b>Conclusions</b>: Favorable survival was achieved through standard neonatal intensive treatment without cardiac surgery. Patients with trisomy 18 complicated by CHD with a high pulmonary flow should be maintained in a stable condition without cardiac surgery due to persistent pulmonary hypertension resulting from vascular abnormalities. Further studies are required to evaluate the long-term effectiveness of cardiac surgery for patients with trisomy 18.</p>

    Background: There is no gold standard sedation method for pediatric cardiac catheterization. In congenital heart diseases with intracardiac shunts, hemodynamic parameters are prone to change depending on the ventilation conditions and anesthetics, although few studies have examined these effects. The purpose of this study was to investigate the effects of two different sedation methods on the hemodynamic parameters. Methods: This study retrospectively evaluated consecutive patients with ventricular septal defect (VSD) below 1 year of age who underwent cardiac catheterization at Aichi Children’s Health and Medical Center, who were divided into age-and VSD diameter-matched general anesthesia (GA) and monitored anesthesia care (MAC) under the natural airway groups (n = 40 each), for comparison of hemodynamic parameters. Results: In the GA group, arterial blood pH and arterial partial pressure of oxygen were significantly higher (p < 0.01), whereas arterial partial pressure of carbon dioxide was significantly lower than in the MAC group (p < 0.01). Mean pulmonary artery pressure (p < 0.05) and systemic blood pressure (p < 0.01) were lower in the GA group. Pulmonary vascular resistance index (p < 0.01) and systemic vascular resistance index (p < 0.01) were also significantly lower in the GA group than the MAC group. There were no significant differences in pulmonary blood flow index, systemic blood flow index, and pulmonary/systemic blood flow ratio between the two groups. Conclusions: Cardiac catheterization under GA in VSD patients results in different hemodynamic parameters compared to that under MAC. In par-ticular, when using pulmonary artery pressure and pulmonary vascular resistance measured under GA for judg-ment regarding the surgical indications or perioperative management, consideration should be given to the fact that these parameters might be lower compared to those measured under MAC.

    Pulmonary hypertension (PH) with developmental lung disease is a life-threatening disease and accounts for 10%–12% of pediatric PH patients. Administration of specific pulmonary vasodilators to pediatric PH patients has brought about improvement of their long-term prognosis. Intravenous epoprostenol therapy is a gold standard therapy for severe idiopathic pulmonary arterial hypertension (IPAH), but there are few reports demonstrating the efficacy of epoprostenol for pediatric PH patients with developmental lung disease, especially when treating with high doses of epoprostenol. Two cases of pediatric PH patients with alveolar capillary dysplasia with misalignment of pulmonary veins (ACD/MPV) and congenital diaphragmatic hernia (CDH) with bronchopulmonary dysplasia (BPD), respectively, treated with epoprostenol above 100 ng/kg/min are presented. In these two cases, severe PH was improved significantly by an aggressive increase of the epoprostenol infusion rate with administration of oral pulmonary vasodilators and appropriate respiratory management, without any significant adverse effects. High-dose epoprostenol therapy may be one of the therapeutic options in pediatric PH patients with developmental lung disease.

    Pulmonary hypertension (PH) is associated with high morbidity in children undergoing hematopoietic stem cell transplantation (HSCT). However, owing to the lack of sequential echocardiography, the nature of the condition is not fully understood. This study was conducted to investigate whether routine echocardiography performed after HSCT could detect patients with PH at an earlier stage and elucidate the role of intervention using tadalafil. The study population comprised 93 consecutive children age <18 years who underwent a total of 109 HSCTs. All patients underwent routine transthoracic echocardiography during HSCT. Four children (4%) with a median age of 4 years (range, 0.7 to 6 years) were found to have PH, and their median tricuspid regurgitation peak velocity (TRV) was 4.1 m/s (range, 3.5 to 4.2 m/s). PH was diagnosed at a median of 52 days (range, 21 to 118 days) after HSCT. Three of them were diagnosed with neuroblastoma, and 1 was diagnosed with infantile leukemia. One patient developed PH after autologous HSCT, and 3 received killer immunoglobulin-like receptor ligand-mismatched cord blood. Busulfan was used for conditioning in all patients, and the proportion of patients receiving this medication was significantly higher in the PH group compared with the non-PH group (100% versus 30%; P = .011). Three of the 4 patients had a durable response (TRV ≤2.8 m/s) at a median of 46 days (range, 14 to 79 days) after starting treatment with tadalafil. No patient experienced exacerbation of PH, and treatment was completed at median of 96 days (range, 46 to 212 days). Our data suggest that routine echocardiography monitoring after HSCT should be considered in children receiving busulfan, although the precise follow-up timing needs further study. In addition, safe and effective administration of tadalafil must be ensured by close monitoring.

    BACKGROUND: Type I interferonopathies are a recently established subgroup of autoinflammatory diseases caused by mutations in genes associated with proteasome degradation or cytoplasmic RNA- and DNA-sensing pathways. OBJECTIVE: This study aimed to unveil the molecular pathogenesis of a patient with novel type I interferonopathy, for which no known genetic mutations have been identified. METHODS: We performed the whole-exome sequencing of a 1-month-old boy with novel type I interferonopathy. We also investigated proteasome activities using patient-derived B lymphoblastoid cell lines (LCLs) and normal LCLs transduced with the mutant gene. RESULTS: Whole-exome sequencing identified a de novo proteasome 20S subunit beta 9 (PSMB9) p.G156D mutation in the patient who developed fever, a chilblain-like skin rash, myositis, and severe pulmonary hypertension due to the hyperactivation of IFN-α. Patient-derived LCLs revealed reduced proteasome activities, and exogenous transduction of mutant PSMB9 p.G156D into normal LCLs significantly suppressed proteasome activities, and the endogenous PSMB9 protein was lost along with the reduction of other immunoproteasome subunits, PSMB8 and PSMB10 proteins. He responded to the administration of a Janus kinase inhibitor, tofacitinib, and he was successfully withdrawn from venoarterial extracorporeal membranous oxygenation. At age 7 months, he received an unrelated cord blood transplantation. At 2 years posttransplantation, he no longer required tofacitinib and experienced no disease recurrence. CONCLUSIONS: We present the case of a patient with a novel type I interferonopathy caused by a de novo PSMB9 p.G156D mutation that suppressed the wild-type PSMB9 protein expression. Janus kinase inhibitor and stem cell transplantation could be curative therapies in patients with severe interferonopathies.

    BACKGROUND: Kawasaki disease (KD) is an idiopathic systemic vasculitis that predominantly damages coronary arteries in children. Various pathogens have been investigated as triggers for KD, but no definitive causative pathogen has been determined. As KD is diagnosed by symptoms, several days are needed for diagnosis. Therefore, at the time of diagnosis of KD, the pathogen of the trigger may already be diminished. The aim of this study was to explore comprehensive pathogens in the sera at the acute stage of KD using high-throughput sequencing (HTS). METHODS: Sera of 12 patients at an extremely early stage of KD and 12 controls were investigated. DNA and RNA sequences were read separately using HTS. Sequence data were imported into the home-brew meta-genomic analysis pipeline, PATHDET, to identify the pathogen sequences. RESULTS: No RNA virus reads were detected in any KD case except for that of equine infectious anemia, which is known as a contaminant of commercial reverse transcriptase. Concerning DNA viruses, human herpesvirus 6B (HHV-6B, two cases) and Anelloviridae (eight cases) were detected among KD cases as well as controls. Multiple bacterial reads were obtained from KD and controls. Bacteria of the genera Acinetobacter, Pseudomonas, Delfita, Roseomonas, and Rhodocyclaceae appeared to be more common in KD sera than in the controls. CONCLUSION: No single pathogen was identified in serum samples of patients at the acute phase of KD. With multiple bacteria detected in the serum samples, it is difficult to exclude the possibility of contamination; however, it is possible that these bacteria might stimulate the immune system and induce KD.

    Perinatal bronchopulmonary dysplasia (BPD) is defined as lung injury in preterm infants caused by various factors, resulting in serious respiratory dysfunction and high mortality. The administration of mesenchymal stem/stromal cells (MSCs) to treat/prevent BPD has proven to have certain therapeutic effects. However, MSCs can only weakly regulate macrophage function, which is strongly involved in the development of BPD. 7ND-MSCs are MSCs transfected with 7ND, a truncated version of CC chemokine ligand 2 (CCL2) that promotes macrophage activation, using a lentiviral vector. In the present study, we show in a BPD rat model that 7ND-MSC administration, but not MSCs alone, ameliorated the impaired alveolarization evaluated by volume density and surface area in the lung tissue, as well as pulmonary artery remodeling and pulmonary hypertension induced by BPD. In addition, 7ND-MSCs, but not MSCs alone, reduced M1 macrophages and the messenger RNA expressions of interleukin-6 and CCL2 in the lung tissue. Thus, the present study showed the treatment effect of 7ND-MSCs in a BPD rat model, which was more effective than that of MSCs alone.

    <p>Percutaneous occlusion of atrial septal defect (ASD) has recently become a standard therapeutic strategy, but little is known about left atrial (LA) function thereafter. The present study aimed to determine LA function in 43 children with ASD and 13 controls based on LA strain measured by two-dimensional echocardiographic speckle tracking (2DE-ST). Among these children, 12 underwent surgery (ASD-S), 31 had device closure (ASD-D), and 13 were included as controls. LA strain was significantly decreased after ASD-D but was not significantly altered after ASD-S, indicating that percutaneous occlusion of an ASD might decrease LA function. Furthermore, the size of the ASD device negatively correlated with LA strain. These results imply that ASD occlusion devices negatively influence LA function and might be important when decided therapeutic strategies for ASD. LA strain measured by 2DE-ST should become a good indicator of LA function after ASD treatment in children.</p>

    Major aortopulmonary collateral arteries (MAPCAs) are unique vessels associated with hypoxia induced by congenital heart disease (CHD). Although MAPCAs are essential to supply blood to the lungs, their development and proliferation can induce life-threatening complications, such as rupture into the lung. Here, we describe a rare case of esophageal bleeding from MAPCAs in a CHD patient, which was successfully treated by transcatheter arterial embolization (TAE). A 16-year-old male with CHD experienced a hematemesis and melena after the Bentall procedure to treat valvular heart disease. Emergent esophagogastroduodenoscopy revealed spurting bleeding from the middle esophageal vessels; accordingly, endoscopic variceal ligation (EVL) was performed. However, he had a hematemesis again after 2 weeks of EVL. The arterial phase of dynamic computed tomography indicated that a MAPCA associated with CHD was the origin of bleeding. Hence, TAE of this MAPCA with a mixture of n-butyl-2-cyanoacrylate and ethiodized oil was performed to prevent re-bleeding. Color Doppler mode in endoscopic ultrasonography via the esophagus revealed mosaic-like signals in MAPCAs located in the esophageal wall. This finding was consistent with tortuous MAPCAs accompanied by turbulent blood flow. When clinicians encounter CHD patients with unexpected massive esophageal bleeding, bleeding related to MAPCAs should be considered.

    We compared the efficacy and safety of infliximab with intravenous immunoglobulin (IVIG), a standard therapy, in a phase 3 trial (NCT01596335) for Japanese patients with Kawasaki disease (KD) showing persistent fever after initial IVIG. Patients with initial IVIG-refractory KD, aged 1-10 years, received a single dose of IV infliximab 5 mg/kg or IV polyethylene glycol-treated human immunoglobulin (VGIH) 2 g/kg on day 0. Primary outcome was defervescence rate within 48 h after the start of treatment. Safety was evaluated through day 56. Overall, 31 patients were randomized (infliximab, n = 16
    VGIH, n = 15)
    31.3% and 60.0% patients discontinued due to worsening KD. Defervescence rate within 48 h was greater with infliximab (76.7%) than VGIH (37.0%) (p = 0.023), and defervescence was achieved earlier with infliximab (p = 0.0072). Coronary artery lesions occurred in 1 (6.3%) and 3 (20.0%) patients receiving infliximab and VGIH, respectively, up to day 21. Adverse events occurred in 15 (93.8%) and 15 (100.0%) patients in the infliximab and VGIH groups, respectively. No serious adverse events in the infliximab group and one in the VGIH group were observed. Infliximab improved the defervescence rate within 48 h and time to defervescence versus standard therapy, and was well tolerated in patients with IVIG-refractory KD.

  40. Successful Infant Pneumonectomy with Unilateral Pulmonary Artery Occlusion Test.

    The use of unilateral pulmonary artery occlusion (UPAO) test for the preoperative evaluation of pneumonectomy was reported in adult patients. On the contrary, in infants, no strategies have yet been recommended to predict hemodynamics after pneumonectomy, nor has use of the UPAO test been reported. We describe the first case of infant with abnormal pulmonary circulation in whom successful pneumonectomy was performed after preoperative evaluation using UPAO test. Right pneumonectomy was planned for an 8-month-old girl, because of decreased right pulmonary function, high risk of pneumothorax, and impaired left lung expansion due to overexpansion caused by severe left bronchial stenosis and bronchomalacia. However, she had also prolonged pulmonary hypertension and there was difficulty in accurate echocardiographic evaluation of its severity due to concomitant left pulmonary artery stenosis. Furthermore, contrast-enhanced computer tomography suggested a certain degree of right pulmonary venous flow, discordant with the result showing scarce right pulmonary flow in perfusion scintigraphy. Predicting postoperative hemodynamic changes was therefore considered difficult. To evaluate these concerns, we performed cardiac catheterization and UPAO test to simulate postoperative hemodynamics. Pulmonary arteriography showed decreased but significant right pulmonary arterial and venous flows. Measurements including pulmonary artery pressure and cardiac index showed no marked changes after occlusion. Based on UPAO test results, the operation was successfully performed and hemodynamics remained stable postoperatively. The UPAO test may be useful for infants with cardiopulmonary impairment to evaluate the tolerability of pneumonectomy.

    蛋白漏出性胃腸症(Protein-Losing Enteropathy: 以下PLE)は単心室型の先天性心疾患に対する機能的修復術であるFontan手術後の患者に発症する予後不良な疾患である。しかし、その発症機序は解明されておらず、治療法も確立していない。近年、消化管疾患だけでなく、様々な疾患の発症や重症化と腸内細菌叢の関連が報告されているが、Fontan術後のPLEと腸内細菌叢の関連についての報告はない。本研究の目的は、次世代シークエンサーを用いたPLE患者に特異的な腸内細菌叢組成の探索と、便のメタボロームによる網羅的な解析により、PLEに関与する菌種、代謝物などの因子を同定することである。
    Fontan術後に発症するPLEはしばしば治療抵抗性で予後不良であるが、発症や活動性を予測するバイオマーカーは開発されていない。本研究はFontan術後PLE患者とPLE未発症患者の腸内細菌叢を、16S rRNAを標的とした次世代シークエンスにより網羅的に解析して比較した。その上で細菌叢の多様性や特定菌種の存在量の変動がPLEの発症や活動性と関連するか検討することを目的とした。研究開始後、計17人のPLE患者とPLE未発症の対照患者23人の患者から同意を得た。PLE患者のうち1名、対照群のうち3名は細菌叢に影響しうる抗菌薬を内服中または検体不良によって除外した。PLE患者のうち活動性PLE患者が7名、1年以上血清アルブミン値: 3.0g/dl以上を維持している寛解期PLE患者が9名であった。対照群は20例となった。便サンプルから細菌DNAを抽出した後、16S rRNA領域のPCR増幅を行い、次世代シークエンンサーMiseqを用いて配列データを得た。配列データを得た後の細菌叢に関する一連の解析を、QIIME2パイプラインにより行った。細菌叢解析の結果、α多様性の指標であるShannon indexとChao1、Faith’s PDは、活動性PLE群で低く、細菌叢の多様性低下が示唆された。各群の細菌叢を主座標分析でプロットしunweghited Unifrac距離を算出すると、活動性PLEと対照群間および活動性PLEと寛解期 PLE間に差を認め、活動性PLE患者は他2群と異なる細菌叢を持つことが示唆された。今後は異なる手法での解析を追加し、成果について学会での報告、論文での発表を計画している。
    本研究では、すでに学内での倫理審査を終えていたこともあり比較的速やかに対象患者の便検体および臨床情報の収集を開始することができた。便検体からのDNA抽出、次世代シークエンスの過程も概ね問題なく施行できている。本課題初年度としては中間解析を行うことができる状況まで進捗したため、概ね順調に進展していると判断した。
    今後は得られたシークエンスデータを元に、Linear discriminant analysis effect size (LEfSe) 解析によって活動性PLE群と寛解期PLE群、対照群の間で存在量が異なる細菌種の同定を進める予定である。また、PICRUSt2(phylogenetic investigation of communities by reconstruction of unobserved states)パイプラインとKEGG(Kyoto Encyclopedia of Genes and Genomes)データベースにより予測メタゲノム解析を行い、各群の細菌叢が持つ代謝経路の存在量を予測する計画である。同時に、現在マウスに下大静脈の部分結紮術を行い、Fontan術後の中心静脈圧上昇を再現したモデル作成を行っている。腸内細菌叢解析の結果、患者糞便やPLEの活動性への関与が疑われる細菌種を同モデルに投与することでPLEを発症または増悪するかの検証を予定している。これにより、特定の細菌叢、菌種が実際にPLE発症や増悪に関与するかを検討する。

To search these proteins, we selectively obtained tissues of obstructive lesions by laser microdissection and performed a comprehensive search using proteomic analysis. Proteome analysis revealed 29 proteins that are upregulated in non-obstructive lesions and 23 proteins that are upregulated in obstructive lesions.

    We conducted search for causal genes in 8 families with familial WPW syndrome by whole-exome sequencing. Only one family identified a pathogenic variant of PRKAG2 gene, already known as the causal gene of familial WPW syndrome. A missense mutation in a causal gene(gene X) of hypertrophic cardiomyopathy was confirmed in one family with WPW syndrome for more than 3 generations. There was no report of WPW syndrome caused by this gene variant, it was considered to be a novel phenotype. The causal gene couldn't detect in the other 6 families.
    We planned an experimental functional analysis to prove that the pathogenic variant of gene X presents with WPW syndrome. We planned to create a model mouse using CRISPER-Cas9 and detect supraventricullar tachycardia caused by WPW syndrome with an implantable electrocardiograph, but we couldn't realize due to equipment and financial problems.

    The purpose in the current study was to develop novel therapies for pulmonary hypertension (PAH) in neonates/children.
    First, we established a pediatric model of pulmonary hypertension (PH).In detail, Sugen 5416 (a VEGF antagonist) was administered subcutaneously to 14-day-old SD rats, and then the rats were put in a hypoxic chamber.Next, we created a model of PH associated with chronic lung disease (CLD), the most common cause of PH in newborns. In detail, early postnatal rats were placed in an 80% hyperoxic incubator.
    These models were treated with SHED; stem cells from human exfoliated deciduous teeth (SHED) and Muse cells, respectively, and the therapeutic effects were evaluated.

    In this study, we studied whether EGF promoted the proliferation of pulmonary alveoli and improved pulmonary hypertension using hyperoxia induced chronic lung disease rat neonate model. The time course study on the duration of hyperoxia revealed that compared to control rats, systolic right ventricular pressure (RVP) and the percentage of muscularized pulmonary vessels increased significantly in the rats after 14 days of hyperoxia challenge. Daily administration of EGF slightly decreased RVP and the percentage of muscularized pulmonary vessels and slightly improved the structure of pulmonary alveoli. Furthermore, hyperoxia decreased the expression of BMPR2, FGFR1 and MMP14 in the lung, which was not restored by EGF. These results showed chronic hyperoxia for 14 days caused chronic lung disease associated pulmonary hypertension in rat neonates. EGF administration showed only slight improvement of pulmonary hypertension and the structure of pulmonary alveoli in this model.
