Acquired pure red cell aplasia (PRCA) and autoimmune hemolytic anemia (AIHA) are rare complications of immunosuppression in pediatric solid organ transplant patients. We report a 14-month-old female child who developed Coombs positive hemolytic anemia and reticulocytopenia while on tacrolimus after cardiac transplantation. She was successfully treated with rituximab after failing treatment with corticosteroids and intravenous immunoglobulins. Clinicians should consider PRCA differential diagnosis in a patient presenting with reticulocytopenia and hemolysis...

BACKGROUND: Bacterial infections represent a major cause of morbidity and mortality in heart transplant recipients. However, data describing the epidemiology and outcomes of these infections in children are limited. METHODS: We analyzed the Pediatric Heart Transplant Study database of patients transplanted between 1993 and 2014 to determine the etiologies, risk factors and outcomes of children with bacterial infections post-heart transplantation. RESULTS: Of 4,458 primary transplants in the database, there were 4,815 infections that required hospitalization or intravenous therapy, 2,047 (42...

Fibrosis is commonly described in heart allografts lost late after transplantation. CMR-derived ECV is a validated measure of DMF in native adult hearts that may predict heart failure and mortality. We explored associations of ECV with histologic myocardial fibrosis and clinical features after pediatric heart transplantation. Twenty-five recipients (7.0±6.3 years at transplant and 10.7±6.5 years post-transplant) were prospectively recruited for CMR and BNP measurement at the time of surveillance biopsy...

Acute cellular rejection (ACR) compromises graft function after heart transplantation (HTX). The purpose of this study was to describe systolic myocardial deformation in pediatric HTX and to determine whether it is impaired during ACR. Eighteen combined cardiac magnetic resonance imaging (CMR)/endomyocardial biopsy (EMBx) examinations were performed in 14 HTX patients (11 male, age 13.9 ± 4.7 years; 1.2 ± 1.3 years after HTX). Biventricular function and left ventricular (LV) circumferential strain, rotation, and torsion by myocardial tagging CMR were compared to 11 controls as well as between patients with and without clinically significant ACR...

Adults with arterial hypertension (HTN) have stroke, myocardial infarction, end-stage renal disease (ESRD), or die at higher rates than those without. In children, HTN leads to target organ damage, which includes kidney, brain, eye, blood vessels, and heart, which precedes "hard outcomes" observed in adults. Left ventricular hypertrophy (LVH) or an anatomic and pathologic increase in left ventricular mass (LVM) in response to the HTN is a pediatric surrogate marker for HTN-induced morbidity and mortality in adults...

BACKGROUND: Extracorporeal membrane oxygenation is a resource-intensive mode of life-support potentially applicable when conventional therapies fail. Given the initial success of extracorporeal membrane oxygenation to support neonates and infants in the 1980s, indications have expanded to include adolescents, adults, and selected moribund patients during cardiopulmonary resuscitation. This single-institution analysis was conducted to evaluate programmatic growth, outcomes, and risk for death despite extracorporeal membrane oxygenation across all ages and diseases...

Extracorporeal membrane oxygenation (ECMO) was developed initially in the 1960s to support refractory respiratory failure in addition to the cardiac support inherent in a venoarterial bypass circuit. Early successes occurred predominantly in the neonatal population with subsequent randomized controlled trials and comprehensive reviews concluding therapeutic efficacy for ECMO in neonatal respiratory failure. In contrast, the evidence supporting ECMO for respiratory failure in children is less definitive. However, although pediatric randomized controlled trials have not been completed, sufficient evidence in support of ECMO as a beneficial therapy for pediatric respiratory failure exists...

Hypertension after kidney transplant is a frequent occurrence in pediatric patients. It is a risk factor for graft loss and contributes to the significant burden of cardiovascular disease (CVD) in this population. The etiology of posttransplant hypertension is multifactorial including donor factors, recipient factors, medications, and lifestyle factors similar to those prevalent in the general population. Ambulatory blood pressure monitoring has emerged as the most reliable method for measuring hypertension in pediatric transplant recipients, and many consider it to be essential in the care of these patients...

Non-ischemic dilated cardiomyopathy (DCM) has been recognized as a heritable disorder for over 25 years, yet clinical genetic testing is non-diagnostic in > 50% of patients, underscoring the ongoing need for DCM gene discovery. Here, whole exome sequencing uncovered a novel molecular basis for idiopathic end-stage heart failure in two sisters who underwent cardiac transplantation at three years of age. Compound heterozygous recessive mutations in TAF1A, encoding an RNA polymerase I complex protein, were associated with marked fibrosis of explanted hearts and gene-specific nucleolar segregation defects in cardiomyocytes, indicative of impaired ribosomal RNA synthesis...

BACKGROUND: There is inadequate power to perform a valid clinical trial in pediatric heart transplantation (HT) using a conventional end-point, because the disease is rare and hard end-points, such as death or graft loss, are infrequent. We sought to develop and validate a surrogate end-point involving the cumulative burden of post-transplant complications to predict death/graft loss to power a randomized clinical trial of maintenance immunosuppression in pediatric HT. METHODS: Pediatric Heart Transplant Study (PHTS) data were used to identify all children who underwent an isolated orthotopic HT between 2005 and 2014 who survived to 6 months post-HT...

Cardiomyopathy is common in long-term survivors of pediatric hematopoietic stem cell transplant (HSCT). Events occurring before and after HSCT when combined with specific insults during HSCT likely contribute to long-term risk. Strategies for detecting subclinical cardiomyopathy prior to patients developing overt heart failure are under investigation. Changes in HSCT preparative regimens and cardioprotective medications administered during chemotherapy may alter the risk for cardiomyopathy. Interventions in long-term survivors such as lifestyle modification and cardioactive medications are of increasing importance...

Background -Supraventricular tachycardia (SVT) is common after heart transplant. Adenosine, the standard therapy for treating SVT in children and adults without transplant, is relatively contraindicated post-transplant due to a presumed risk of prolonged atrioventricular (AV) block in denervated hearts. This study tested whether adenosine caused prolonged asystole after transplant and if it was effective in blocking AV nodal conduction in these patients. Methods -This was a single center prospective clinical study including healthy heart transplant recipients ages 6 months - 25 years presenting for routine cardiac catheterization during 2015 - 2016...

The techniques and outcomes of heart transplantation in the pediatric population continue to improve over the years, although the supply of organs remains limited. Donor-to-recipient size matching is critical, especially in neonates and small infants. We present a novel strategy for heart transplantation that includes the Lecompte maneuver because of the features of the donor allograft available in a 8-month-old patient with a cardiac fibroma. We discuss the basis principles for extending the indication of this procedure to exceptional transplantation scenarios and describe the results at long-term follow-up...

Dilated cardiomyopathy in children still has a poor prognosis with high rates of mortality and cardiac transplantation (resp. around 20 and 25%). Awaiting transplantation or possible recovery, these pediatric patients are mechanically supported with extracorporeal membrane oxygenation or a paracorporeal ventricular assist device, both resulting in higher survival rates but also entailing considerable risks of infection, thrombosis, or bleeding. A new indication for an old technique, i.e., pulmonary artery banding, presents itself as an interesting alternative to mechanical circulatory support in selected infants and small children with dilated LV cardiomyopathy and preserved RV function...
