About This Topic

Solid organ transplantation is an established life -saving therapy for end-organ diseases of the kidney, liver, heart, and lungs. The improved patient and graft survivals have been attributed to advancements in surgical techniques and effective immunosuppressive therapies. However, immune suppression, pre-existing co-morbidities, and potential surgical complications can result in infectious complications after organ transplantation. In this particular issue of OBM transplantation, solicited articles will focus on review of current approaches to the diagnosis and management of post-transplant infections in solid organ transplant recipients due to bacterial, viral and fungal pathogens. Each article will also address strategies of screening and prevention of post-transplant infections.

Title: Clinical management of bacterial and fungal infections in the early and late post-transplant
Authors: Umberto Baccarani, MD, PhD, FEBS, Elda Righi, MD
Abstract: Bacterial and fungal infections negatively impact the outcomes of liver transplant recipients, increasing mortality rates especially in the early post-transplant period. Abdominal, biliary tract, and bloodstream infections caused by Gram-negative bacteria such as Enterobacteriaceae and Pseudomonas aeruginosa and Gram-positive bacteria (e.g., Staphylococcus aureus, including methicillin-resistant strains) are commonly seen in liver transplant recipients within the first month following surgery due to the type of operation and potential surgical complications. In the late post-transplant period (> 6 months post-transplant), infections with uncommon presentations are possible and physicians should be aware of the risk of severe late bacterial and fungal infections. Due to prolonged hospitalisation and common exposure to broad-spectrum antibiotics and invasive procedures and/or devices, liver transplant recipients are at high-risk of infections caused by multidrug-resistant bacteria. The increase in antimicrobial resistance is one of the biggest challenges in managing post-transplant infections due to the lack of new targeted antimicrobial therapies against highly resistant bacteria. The main challenges from a surgical and medical point of view along with the management of bacterial and fungal infections in liver transplant recipients are discussed.

Abstract:
Background: Human Papilloma virus (HPV) infections are an increasingly concerning etiology for post-transplantation viral-related malignancies. The nonavalent HPV vaccine (Gardasil 9) affords transplant recipients the best opportunity for malignancy prevention, but remains underutilized. Not previously reported for solid organ transplant recipients, we studied influential factors for HPV vaccine non-initiation.
Methods: This survey, conducted from May to December 2017, examined influential factors for HPV vaccine non-initiation. HPV-related disease period prevalence was also analyzed in this regional survey.
Results: Of the 164 patients approached for the study, 157 participated and 154 completed the survey resulting in a 95% response rate. Twenty-nine percent of patients within the United States Food and Drug Administration (FDA) approved age range had started or completed the HPV vaccine series at survey administration. The most significant reason for HPV vaccine non-initiation among age eligible transplant patients was a reduced physician intention to recommend.
Conclusions: HPV vaccination remains underutilized in solid organ transplant patients. Emphasis on physician intention to recommend HPV vaccination will reduce vaccine non-initiation rates.

Abstract:
Lung transplant recipients are at greater risk of viral infections as compared to other solid organ transplant recipients due to constant exposure to the external environment. There are no standardized methods for surveillance, prevention, or treatment of these infections despite their association with increased morbidity and mortality. Various studies have shown linked viral infections with acute cellular rejection and chronic allograft dysfunction, and emerging data indicates a role in antibody mediated rejection. This paper will review the prevalence and impact of community acquired respiratory viruses in lung transplant recipients, review the evidence linking viral infections to long term graft dysfunction and rejection, describe existing strategies for surveillance and prevention, and list the currently available and promising investigational therapies.
