Pediatr Transplant 2019; 23:e13518. [PMID: 31210404 DOI: 10.1111/petr.13518] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2018] [Revised: 04/09/2019] [Accepted: 04/26/2019] [Indexed: 02/06/2023]
Abstract
Subjective evaluation of medical care and disease outcomes from patients' perspectives has become increasingly important. Patient-reported outcome measures (PROMs) play a prominent role in engaging patients, capturing their experiences and improving patient care. This systematic review sought to identify PROMs that are used in the field of pediatric solid organ transplantation, with the aim to inform the implementation of PROMs into clinical practice for this population. A systematic review of English language, peer-reviewed articles was performed on key health science databases to identify publications using PROMs in pediatric solid organ transplantation. The search yielded 3670 articles, with a final data set of 62 articles that included 47 different PROMs. The three most frequently used PROMs included the following: (a) PedsQL™ Generic Core Scales (n = 25); (b) Children's Depression Inventory (n = 6); and (c) Child Health Questionnaire (n = 6). Of the 47 PROMs, 42 were generic and five were disease-specific; only six PROMS had a documented psychometric evaluation within a pediatric solid organ transplant population. This review outlines the attributes of the instruments (eg, domains captured), as well as the psychometric properties of those evaluated. PROMs are increasingly used in the field of pediatric transplantation; however, there are limited details in the current literature about their conceptual underpinnings and psychometric properties. This review highlights the need for additional psychometric evaluation of identified measures to establish the necessary foundation to inform the implementation of PROMs into clinical care for pediatric solid organ transplant patients.

Abstract
Transplantation outcomes are known to be affected by multiple factors, including donor and recipient sex. Aside from the physiological characteristics of male and female donor allografts, accumulating evidence suggests that additional features underlie sex-specific immune responses that affect graft survival. We discuss here aspects of innate and adaptive alloimmunity that are specific to males and females in the context of underlying genetic and hormonal factors. These differences likely contribute to the observed disparities in graft survival. Understanding these features in more detail may lead to improved strategies for optimizing the results of organ transplantation.

Abstract
BACKGROUND Despite the growing appreciation of the importance of sex and gender considerations in transplantation research, there is currently no framework or good practice guidelines for the appropriate handling of sex and gender issues in human allotransplantation research. METHODS We will conduct a scoping review to synthesize the evidence on how matters of sex and gender have been handled in human allotransplantation research. We will survey the literature discussing sex and gender in relation to transplantation, including adult and pediatric patients, hematopoietic and solid organ transplant recipients as well as organ donors. We will search MEDLINE and Embase for literature discussing sex and gender in relation to transplantation. Two reviewers will independently evaluate the eligibility of all identified titles and abstracts for inclusion in the full text review, as well as data extraction. Descriptive data and information on how sex and gender have been considered in human transplantation research will be reported. DISCUSSION This scoping review will be an important stepping stone towards the development of good practice guidelines on study design and analysis considerations when handling sex and gender issues in human transplantation research. This scoping review can also help identify methodological issues that restrict the translation of transplantation research findings into clinical practice related to underestimation of sex/gender differences. This review will ultimately identify major gaps, inform donor-recipient selection, guide personalized interventions, and prioritize research recommendations in human transplantation research.

Abstract
The 13th Banff Conference on Allograft Pathology was held in Vancouver, British Columbia, Canada from October 5 to 10, 2015. The cardiac session was devoted to current diagnostic issues in heart transplantation with a focus on antibody-mediated rejection (AMR) and small vessel arteriopathy. Specific topics included the strengths and limitations of the current rejection grading system, the central role of microvascular injury in AMR and approaches to semiquantitative assessment of histopathologic and immunophenotypic indicators, the role of AMR in the development of cardiac allograft vasculopathy, the important role of serologic antibody detection in the management of transplant recipients, and the potential application of new molecular approaches to the elucidation of the pathophysiology of AMR and potential for improving the current diagnostic system. Herein we summarize the key points from the presentations, the comprehensive, open and wide-ranging multidisciplinary discussion that was generated, and considerations for future endeavors.

Abstract
Infants with fatal cardiac disease often die awaiting transplantation because of the shortage of donor hearts. The Hospital for Sick Children (HSC), Toronto, Canada, has researched and applied the concept of crossing the blood group compatibility barrier. Heart transplantation at HSC unrestricted by ABO compatibility greatly contributed to decreasing the mortality rate among infants on the waiting list from 58% to 10%. From January 1996 to January 2002, 16 infants less than 14 months of age received ABO-incompatible heart transplants at our institution. The cardiopulmonary bypass (CPB) circuit is primed with additional volume to replace the patient’s blood volume. Packed red blood cells (PRBC) used in priming must be ABO-compatible with the recipient. All plasma components and platelets must contain no anti-A or anti-B antibodies to donor or recipient. CPB is initiated and the patient’s venous blood is collected into a transfusion bag and sent to the blood bank. The total amount collected should be one and a half to two times the patient’s blood volume. The plasma is separated and discarded, returning only the PRBC, thus reducing the concentration of circulating antibodies to blood group antigens. Our team has experienced an 87% survival rate with this technique. The success is believed to be associated with the recipients’ immunologic immaturity. Newborns do not produce isohemagglutinins, and serum anti-A and anti-B antibody titers usually remain low until 12-14 months of age. The complement system is not fully developed, therefore, the mediators of hyperacute rejection are absent during early infancy. Heart transplantation unrestricted by the need for ABO compatibility would effectively expand the available donor pool and decrease waiting times.

Abstract
Cardiac remodeling is associated with plasma biomarkers of fibrinogenesis, inflammation, and oxidative stress, and upregulation of mitogenic, pro-fibrotic, and apoptotic signaling pathways. Our primary objective was to evaluate biomarker and subcellular myocardial changes in pediatric heart transplant recipients. Fifty-two-week prospective, randomized (tacrolimus, Tac, vs. cyclosporine, CsA), open-label, parallel group study. Serial myocardial biopsies were probed for mitogenic and pro-inflammatory proteins. Plasma biomarkers of oxidative stress (F2α isoprostanes, nitrotyrosine), and inflammation and oxidation (hsCRP and cystatin-C) were measured. Nine of 11 randomized patients completed the study (four Tac, five CsA). Mean levels of F2α isoprostanes, hsCRP, and cystatin-C were maximal at Week 2. Peak activation of all MAP kinases in myocardial tissue was maximal at Week 10; no association was seen with rejection. Cardiac Bax/Bcl-2 levels (index of apoptosis) correlated negatively with F2α isoprostanes at Week 2 (r = -0.88) and with hsCRP at Week 52 (r = -0.67). At Week 52, hsCRP levels correlated positively with molecular indices of cardiac cell growth. We found evidence of systemic and myocardial oxidative damage and inflammation early posttransplant, which may be related to the remodeling process. Further study is needed to better understand the cardiac and systemic repair processes following pediatric heart transplantation.

Abstract
During the last 25 years, antibody-mediated rejection of the cardiac allograft has evolved from a relatively obscure concept to a recognized clinical complication in the management of heart transplant patients. Herein we report the consensus findings from a series of meetings held between 2010-2012 to develop a Working Formulation for the pathologic diagnosis, grading, and reporting of cardiac antibody-mediated rejection. The diagnostic criteria for its morphologic and immunopathologic components are enumerated, illustrated, and described in detail. Numerous challenges and unresolved clinical, immunologic, and pathologic questions remain to which a Working Formulation may facilitate answers.
