Transplant Complications

Dermatological manifestations following transplantation are common but important to recognize and diagnose since they may be severe and life-threatening if not adequately and promptly treated. This chapter provides a systematic overview of the types of skin disease that may be encountered in children that have received a haematological or solid organ transplant. Complications relating to immunosuppression include an increased susceptibility to bacterial, viral, and fungal infections which may be significantly more virulent and hazardous in the context of reduced host immunity. Immune suppressant drugs may also cause drug rashes and aesthetic complications such as acne, hypertrichosis, or gingival hypertrophy, as well as longer-term risks from the development of malignancy. It is also important to recognize the range of mucocutaneous signs of acute and chronic graft versus host disease following bone marrow and solid organ transplantation which, again, may be severe and associated with significant morbidity and mortality.

Malassezia Restricta

Emerging fungal infections are a major challenge in solid organ transplantation (SOT) and are associated with high morbidity and mortality. We report two cases of Malassezia restricta pneumonia in SOT recipients. Infections were diagnosed with molecular analysis and histology. Patients were treated with antifungal therapy and have fully recovered.

Solid Organ Transplant Recipients

Cytomegalovirus is the classic opportunistic infection after solid organ transplantation. This review will discuss updates and future directions in the diagnosis, prevention and treatment of CMV infection in solid organ transplant recipients. Antiviral prophylaxis and pre-emptive therapy are the mainstays of CMV prevention, but they should not be mutually exclusive and each strategy should be considered depending on a specific situation. The lack of a widely applicable viral load threshold for diagnosis and preemptive therapy is emphasized as a major factor that should pave the way for an individualized approach to prevention. Valganciclovir and intravenous ganciclovir remain as drugs of choice for CMV management, and strategies for managing drug-resistant CMV infection are enumerated. There is increasing use of CMV-specific cell-mediated immune assays to stratify the risk of CMV infection after solid organ transplantation, and their potential role in optimizing CMV prevention and treatment efforts is discussed.

Life Threatening

Despite the availability of a variety of antifungal drugs, opportunistic fungal infections still remain life-threatening for immunocompromised patients, such as those undergoing allogeneic hematopoietic cell transplantation or solid organ transplantation. Suboptimal efficacy, toxicity, development of resistant variants and recurrent episodes are limitations associated with current antifungal drug therapy. Adjunctive immunotherapies reinforcing the host defense against fungi and aiding in clearance of opportunistic pathogens are continuously gaining ground in this battle. Here, we review alternative approaches for the management of fungal infections going beyond the state of the art and placing an emphasis on fungus-specific T cell immunotherapy. Harnessing the power of T cells in the form of adoptive immunotherapy represents the strenuous protagonist of the current immunotherapeutic approaches towards combating invasive fungal infections. The progress that has been made over the last years in this field and remaining challenges as well, will be discussed.

Risk Of Cancer

IntroductionSolid organ transplant patients are counselled regarding increased risk of cancer (principally due to their need for lifelong immunosuppression) and it ranks as one of their biggest self-reported worries. Post-transplantation cancer is common, associated with increased healthcare costs and emerging as a leading cause of post-transplant mortality. However, epidemiology of cancer post-transplantation remains poorly understood, with limitations including translating data from different countries and national data being siloed across different registries and/or data warehouses.Methods and analysisStudy methodology for Epidemiology of Cancer after Solid Organ Transplantation involves record linkage between the UK Transplant Registry (from NHS Blood and Transplant), Hospital Episode Statistics (for secondary care episodes from NHS Digital), National Cancer Registry (from cancer registration data hosted by Public Health England) and the National Death Registry (from NHS Digital). Deterministic record linkage will be conducted by NHS Digital, with a fully anonymised linked dataset available for analysis by the research team. The study cohort will consist of up to 85 410 solid organ transplant recipients,who underwent a solid organ transplant in England between 1 January 1985 and 31 December 2015, with up-to-date outcome data.Ethics and disseminationThis study has been approved by the Confidentiality Advisory Group (reference: 16/CAG/0121), Research Ethics Committee (reference: 15/YH/0320) and Institutional Review Board (reference: RRK5471). The results of this study will be presented at national and international conferences, and manuscripts with results will be submitted for publication in high-impact peer-reviewed journals. The information produced will also be used to develop national evidence-based clinical guidelines to inform risk stratification to enable risk-based clinical follow-up.Trial registration numberNCT02991105.

Solid Organ Transplant Recipients

Solid organ transplant recipients are at increased risk for infections due to chronic immunosuppression. Diarrhea is a commonly encountered problem post transplantation, with infectious causes of diarrhea being a frequent complication. Viral infections/enteritides in solid organ transplant recipients often result from frequently encountered pathogens in this population such as cytomegalovirus, adenovirus, and norovirus. However, several emerging viral pathogens are increasingly being recognized as more sensitive diagnostic techniques become available. Treatment is often limited to supportive care and reduction in immunosuppression, though antiviral therapies mayplay a role in the treatment in certain diseases. Viral enteritis is an important entity that contributes to morbidity and mortality in transplant recipients.

Respiratory infections pose a significant threat to the success of solid organ transplantation, and the diagnosis and management of these infections are challenging. The current narrative review addressed some of these challenges, based on evidence from the literature published in the last 20 years. Specifically, we focused our attention on (i) the obstacles to an etiologic diagnosis of respiratory infections among solid organ transplant recipients, (ii) the management of bacterial respiratory infections in an era characterized by increased antimicrobial resistance, and (iii) the development of antimicrobial stewardship programs dedicated to solid organ transplant recipients.
