Pediatric Infectious Disease (ID) clinicians play a critical role in helping prevent and mitigate infectious risks in children peri- and post-transplantation. Prevention starts during the pre-transplant evaluation and persists throughout the solid organ transplant and hematopoietic cell transplant continuum. The pre-transplant evaluation is an opportunity to screen for latent infections, plan preventative strategies, optimize immunizations, and discuss risk mitigation practices. An ideal...

The present AST-IDCOP guidelines update information on strategies for safe living after organ transplantation. While transplantation carries an increased risk for infection from the recipient's environment due to lifelong immunosuppression, the goal is for the recipient to be able to return to their home and live as normal a life as possible with a functioning graft. The current guideline provides updates to prior recommendations including additions on infections from water and food sources,...

Infections are an important cause of morbidity and mortality after transplantation. Some of these infections are environmental and geographically or seasonally important. West Nile virus is one such infection, tied to the epidemiology of infected mosquitos which varies over time. It can cause disease for a transplant recipient either from direct inoculation from an infected mosquito or as a donorderived infection. This chapter reviews current data about the epidemiology of West Nile virus,...

Transplant infectious diseases is a rapidly emerging subspecialty within pediatric infectious diseases reflecting the increasing volumes and complexity of this patient population. Incorporating transplant infectious diseases into the transplant process would provide an opportunity to improve clinical outcome and advocacy as well as expand research. The relationship between transplant physicians and infectious diseases (ID) specialists is one of partnership, collaboration, and mutual...

Pediatric solid organ transplant (SOT) recipients with splenic dysfunction are at increased risk for infections, and tailored guidance on the management of asplenia/hyposplenism among SOT recipients is often lacking. The purpose of this article is to provide practice recommendations via a frequently asked questions (FAQs) format that focuses on three main domains: the identification of asplenia/hyposplenism among SOT recipients/candidates, prophylactic strategies for mitigating the risk of...

The Practice Guidelines Committee of the American Society for Transplantation and Cellular Therapy partnered with its Transplant Infectious Disease Special Interest Group to update its 2009 compendium-style infectious diseases guidelines for the care of hematopoietic cell transplant (HCT) recipients. A new approach was taken with the goal of better serving clinical providers by publishing each standalone topic in the infectious disease series as a concise format of frequently asked questions...

Despite clinical and laboratory screening of potential donors for transmissible disease, unexpected transmission of disease from donor to recipient remains an inherent risk of organ transplantation. The Disease Transmission Advisory Committee (DTAC) was created to review and classify reports of potential disease transmission and use this information to inform national policy and improve patient safety. From January 1, 2008 to December 31, 2017, the DTAC received 2185 reports; 335 (15%) were...

Abstract The COVID-19 pandemic continues to generate challenges for pediatric solid organ transplant (SOT) recipients and their families. As rates of COVID-19 fluctuate, new SARS-CoV-2 variants emerge, and adherence to and implementation of mitigation strategies vary from community to community, questions remain about the best and safest practices to prevent COVID-19 in vulnerable patients. Notably, decisions about returning to school remain difficult. We assembled a team of...

Cryptococcus species can cause serious life-threatening infection in solid organ transplant recipients by reactivation of prior infection, post-transplant de novo infection, or donor transmission from the transplanted organ. Although previously reported in the literature, the extent of donor-derived cryptococcosis in the United States has not been documented. We analyzed potential donor-derived Cryptococcus transmission events reported to the Organ Procurement and Transplantation Network...

Mycobacterium tuberculosis can be transmitted via organ donation and result in severe outcomes. To better understand donor-derived tuberculosis (DDTB), all potential transmissions reported to the Organ Procurement and Transplantation Network (OPTN) Ad Hoc Disease Transmission Advisory Committee between 2008 and 2018 were analyzed. Among 51 total reports, nine (17%) (9 donors/35 recipients) had ≥ 1 recipient with proven/probable disease transmission. Of these, eight were reported due to...

SARS-CoV-2 is transmissible through lung transplantation, and outcomes among SARS-CoV-2-infected solid organ transplant (SOT) recipients may be severe; however, transmission risk to extrapulmonary organ recipients and recent (within 30 days of transplantation) SARS-CoV-2-infected recipient outcomes are unclear.During March 2020-March 2021, potential SARS-CoV-2 transmissions through SOT reported to the Organ Procurement and Transplantation Network were investigated. Laboratory and...

Background: Norovirus (NoV) can cause chronic relapsing and remitting diarrhea in immunocompromised patients. Few multicenter studies have described the clinical course, outcomes, and complications of chronic NoV in transplant recipients.

Hepatitis B virus (HBV) can be transmitted from organ donor to recipient, but details of transmission events are not widely published. The Disease Transmission Advisory Committee (DTAC) evaluated 105 cases of potential donor derived transmission events of HBV between 2009-2017. Proven, probable or possible transmission of HBV occurred in 25 (23.8%) cases. Recipients of liver grafts were most commonly infected (20 of 21 exposed recipients) compared to 9 of 21 exposed non-hepatic recipients....

The International Pediatric Transplant Association (IPTA) convened an expert consensus conference to assess current evidence and develop recommendations for various aspects of care relating to post-transplant lymphoproliferative disorder after solid organ transplantation in children. In this report from the Prevention Working Group, we reviewed the existing literature regarding immunoprophylaxis and chemoprophylaxis, and pre-emptive strategies. While the group made a strong recommendation...

The International Pediatric Transplant Association convened an expert consensus conference to assess current evidence and develop recommendations for various aspects of care relating to post-transplant lymphoproliferative disorders after solid organ transplantation in children. In this report from the Viral Load and Biomarker Monitoring Working Group, we reviewed the existing literature regarding the role of Epstein-Barr viral load and other biomarkers in peripheral blood for predicting the...

The International Pediatric Transplant Association convened an expert consensus conference to assess current evidence and develop recommendations for various aspects of care relating to post-transplant lymphoproliferative disorders (PTLD) after pediatric solid organ transplantation. This report addresses the outcomes of deliberations by the PTLD Management Working Group. A strong recommendation was made for reduction in immunosuppression as the first step in management. Similarly, strong...

Background Decisions to transplant organs from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid test-positive (NAT+) donors must balance risk of donor-derived transmission events (DDTE) with the scarcity of available organs. Methods Organ Procurement and Transplantation Network (OPTN) data were used to compare organ utilization and recipient outcomes between SARS-CoV-2 NAT+ and NAT– donors. NAT+ was defined by either a positive upper or lower respiratory tract (LRT)...
