Michael O Killian
Few studies have identified the psychosocial characteristics of those children and their families associated with future non-adherence to immunosuppressive medications following a heart or lung transplant. UNOS data and medical records information were used to test the association between patient and family psychosocial characteristics and medication adherence. Medication adherence outcomes were obtained using the physician assessments in the UNOS data and measured through patient-level standard deviation scores of immunosuppressive medication blood levels...

We aimed to analyze characteristics of encephalopathy after both hematopoietic stem cell and solid organ pediatric transplantation. We retrospectively reviewed medical records of 662 pediatric transplant recipients (201 with liver transplantation [LT], 55 with heart transplantation [HT], and 67 with kidney transplantation [KT], 339 with allogeneic hematopoietic stem cell transplantation [HSCT]) who received their graft organs at Asan Medical Center between January 2000 and July 2014. Of the 662 patients, 50 (7...

The objective of this study is to assess changes in cardiac deformation during acute cellular- and antibody-mediated rejection in pediatric HT recipients. Pediatric HT recipients aged ≤18 years with at least one episode of biopsy-diagnosed rejection from 2006 to 2013 were included. Left ventricular systolic S (SS) and SR (SSr) data were acquired using 2D speckle tracking on echocardiograms obtained within 12 h of right ventricular endomyocardial biopsy. A mixed effect model was used to compare cardiac deformation during CR (Grade ≥ 1R), AMR (pAMR ≥ 2), and mixed rejection (CR and AMR positive) versus no rejection (Grade 0R and pAMR 0 or 1)...

Early primary graft failure after pediatric orthotopic heart transplantation (OHT) has a high mortality rate and can occur due to several causes including but not limited to prolonged graft ischemia time, suboptimal preimplant myocardial preservation, hyperacute rejection, and maladaptation of the graft to the host's hemodynamic status. Mechanical circulatory support with either extracorporeal membrane oxygenation (ECMO) or ventricular assist device has been used for the rescue of primary graft failure in pediatric patients after heart transplant...

Heart rate variability is primarily regulated by the autonomic nervous system. Heart transplant recipients undergo surgical denervation of the graft, which results in interruption of autonomic innervation with resultant diminished heart rate variability although some degree of autonomic control may return. This study aimed to characterize heart rate variability in this population. We report a retrospective review of Holter monitor data from transplanted patients between 2005 and 2013. Studies with significant atrial or ventricular arrhythmias were excluded...

The process of pediatric solid organ transplantation (SOT) places new and increased stressors on patients and family members. Measures of family functioning may predict psychological and health outcomes for pediatric patients and their families, and provide opportunity for targeted intervention. This systematic review investigated parent and family functioning and factors associated with poorer functioning in the pediatric SOT population. Thirty-seven studies were identified and reviewed. Studies featured a range of organ populations (eg, heart, liver, kidney, lung, intestine) at various stages in the transplant process...

Myocardial dysfunction and heart failure are common in pediatric patients with congenital and acquired heart disease. Alkaline phosphatase (AP) has been suggested as a biomarker for myocardial dysfunction after Fontan operation. We hypothesized that pediatric patients with myocardial dysfunction requiring orthotopic heart transplant (OHT) have diminished AP compared to normal. A retrospective review was performed in all patients who underwent OHT at Arkansas Children's Hospital between January 2007 and October 2012...

As methods for human leukocyte antigens (HLA) antibody detection have evolved and newer solid phase assays are much more sensitive, the last 15 years has seen a renewed focus on the importance of HLA antibodies in solid organ transplant rejection. However, there is still much controversy regarding the clinical significance of antibody level as depicted by the mean fluorescence intensity of a patient's neat serum. Emerging techniques, including those that identify antibody level and function, show promise for the detection of individuals at risk of allograft rejection, determination of the effectiveness of desensitization prior to transplant, and for monitoring treatment of rejection...

The presence of CD may be viewed as a relative contraindication to transplantation; however, its impact on pediatric HTx outcomes is poorly characterized. The aim of this study was to assess the impact of CD on pediatric HTx outcomes using academic progress as a surrogate measure of cognitive performance. The OPTN database was queried for all pediatric HTx recipients (2004-2014) with reported academic progress. Multivariable analysis assessed the impact of DGL and the need for SE on post-HTx graft survival...

BACKGROUND: Research comparing the survival of children with familial dilated cardiomyopathy (FDCM) to that of children with idiopathic dilated cardiomyopathy (IDCM) has produced conflicting results. METHODS AND RESULTS: We analyzed data from children with FDCM or IDCM using the National Heart, Lung, and Blood Institute-funded Pediatric Cardiomyopathy Registry. Compared to children with IDCM (n=647), children with FDCM (n=223) were older (mean 6.2 versus 4.5 years, P<0...

Purpose. The most recent International Society for Heart and Lung Transplantation (ISHLT) biopsy scale classifies cellular and antibody-mediated rejections. However, there are cases with acute decline in left ventricular ejection fraction (LVEF ≤ 45%) but no evidence of rejection on biopsy. Characteristics and treatment response of this biopsy negative rejection (BNR) have yet to be elucidated. Methods. Between 2002 and 2012, we found 12 cases of BNR in 11 heart transplant patients as previously defined. One of the 11 patients was treated a second time for BNR...

BACKGROUND: Combined heart and liver transplantation (CHLT) in the pediatric population involves a complex group of patients, many of whom have palliated congenital heart disease (CHD) involving single ventricle physiology. OBJECTIVE: The purpose of this study was to describe the perioperative management of pediatric patients undergoing CHLT at a single institution and to identify management strategies that may be used to optimize perioperative care. METHODS: We did a retrospective database review of all patients receiving CHLT at a children's hospital between 2006 and 2014...

Diabetes mellitus is a recognized complication of SOT in adults and is associated with decreased graft and patient survival. Little is known about NOD in pediatric HT recipients. We aimed to characterize the incidence and describe risk factors for development of NOD after HT in children. Children who developed diabetes after HT were identified from the OPTN database. Demographic and clinical data before and after transplant were compared between patients with and without NOD. A total of 2056 children were included, 56% were male, 54% were Caucasian, and 62% had cardiomyopathy prior to HT...

BACKGROUND: Current knowledge of antibody-mediated rejection (AMR) after heart transplantation (HT) stems largely from adult data. Using the Pediatric Heart Transplant Study (PHTS) database, we report the incidence of AMR, describe treatment, and evaluate outcomes for treated AMR in children after HT. METHODS: We queried the PHTS database for patients <18 years of age undergoing primary HT between January 2010 and December 2014. An AMR episode was defined as either a biopsy consistent with pathologic AMR or a rejection event based on immunotherapy augmentation directed against antibody production...

BACKGROUND: With advances in immunosuppressive therapy, heart transplantation is currently recommended as the only established surgical treatment for refractory heart failure. However, chronic immunosuppression increases the risk for malignancy. Everolimus (EVR) is a potent mammalian target of rapamycin inhibitor that is used after transplantation and to treat advanced malignancies, as we have done in Taiwan after heart transplantation since 2004. Mycophenolate mofetil (MMF) and EVR are frequently used as cell-cycle inhibitors to optimize post-transplantation outcomes...

Heart failure is a progressive and fatal disease impacting millions of American each year. Divided into stages, heart failure presents with progressive symptoms requiring a wide range of medical treatments. Treatments include diet and lifestyle changes, medications, electrical therapies (defibrillator and/or cardiac resynchronization therapy), as well as mechanical circulatory support. Cardiac transplant is the gold standard treatment of heart failure, although the availability of donors limits the utility of a cardiac transplant...

Heart failure impacts a multitude of individuals each year. Treatment is based on the progression of the disease and severity of symptoms. Cardiac transplant is the gold standard treatment of advanced heart failure, although the availability of organs limits the number of transplants received each year. Postoperative care and monitoring for cardiac transplant is complex and requires specialized nurses and providers at transplant centers for successful outcomes. This article outlines cardiac transplant from preoperative care through transplant, as well as posttransplant monitoring and care including discharge...
