Sot infection

BACKGROUND: The prevalence and outcomes of COVID-19-associated invasive fungal infections (CAIFIs) in solid organ transplant recipients (SOTRs) remain poorly understood. METHODS: A retrospective cohort study of SOTRs with COVID-19 admitted to 5 hospitals within Johns Hopkins Medicine was performed between March 2020 and March 2022. Cox regression multilevel mixed-effects ordinal logistic regression was used. RESULTS: In the cohort of 276 SOTRs, 22 (8%) developed IFIs...

Viral infections are a major source of morbidity and mortality in the context of immune deficiency and immunosuppression following allogeneic hematopoietic cell (allo-HCT) and solid organ transplantation (SOT). The pharmacological treatment of viral infections is challenging and often complicated by limited efficacy, the development of resistance, and intolerable side effects. A promising strategy to rapidly restore antiviral immunity is the adoptive transfer of virus-specific T cells (VST). This therapy involves the isolation and ex vivo expansion or direct selection of antigen-specific T cells from healthy seropositive donors, followed by infusion into the patient...

Epstein-Barr Virus (EBV) diseases, including EBV-associated post-transplant lymphoproliferative disorder (PTLD) remain important causes of morbidity and mortality in children undergoing solid organ transplantation (SOT) and hematopoietic cell transplantation (HCT). Despite progress in the prevention of EBV disease including PTLD (EBV/PTLD) in HCT, key questions in the prevention, and management of these infectious complications remain unanswered. The goal of this manuscript is to highlight key points and recommendations derived from the consensus guidelines published by the International Pediatric Transplant Association and the European Conference on Infections in Leukemia for children undergoing SOT and HCT, respectively...

Despite current prophylaxis regimens, cytomegalovirus (CMV) is common in hematopoietic cell transplantation (HCT) and solid organ transplantation (SOT) and remains a significant cause of morbidity and mortality. Newer antiviral medications are reshaping the landscape for prevention and treatment of CMV DNAemia, infection, and disease. Letermovir is approved for CMV prevention in adult HCT patients and is attractive due to the absence of marrow suppression seen with ganciclovir/valganciclovir. Letermovir should not be routinely used for CMV treatment due to its low threshold for resistance...

Respiratory viral infections (RVIs) are among the leading cause of morbidity and mortality in pediatric hematopoietic stem cell transplant (HCT) and solid organ transplant (SOT) recipients. Transplant recipients remain at high risk for super imposed bacterial and fungal pneumonia, chronic graft dysfunction, and graft failure as a result of RVIs. Recent multicenter retrospective studies and prospective studies utilizing contemporary molecular diagnostic techniques have better delineated the epidemiology and outcomes of RVIs in pediatric transplant recipients and have advanced the development of preventative vaccines and treatment interventions in this population...

PURPOSE OF REVIEW: Infections in lung transplant recipients remain a major challenge and can affect lung allograft function and cause significant morbidity and mortality. New strategies for the prevention and treatment of infection in lung transplantation have emerged and are reviewed. RECENT FINDINGS: For important vaccine preventable infections (VPIs), guidance has been updated for at risk solid organ transplant (SOT) recipients. However, data on the efficacy of newer vaccines in lung transplant, including the respiratory syncytial virus (RSV) vaccine, are limited...

Neurologic complications, both infectious and non-infectious, are frequent among hematopoietic cell transplant (HCT) and solid organ transplant (SOT) recipients. Up to 46% of HCT and 50% of SOT recipients experience a neurological complication, including cerebrovascular accidents, drug toxicities, as well as infections. Defects in innate, adaptive, and humoral immune function among transplant recipients predispose to opportunistic infections, including central nervous system (CNS) disease. CNS infections remain uncommon overall amongst HCT and SOT recipients, compromising approximately 1% of total cases among adult patients...

Human adenovirus (HAdV) and cytomegalovirus (HCMV) are cause of high morbidity and mortality in patients receiving solid organ (SOT) and hematopoietic stem cell transplantations (HSCT). Immunosuppressors are universally used to prevent graft-versus-host disease (GVHD) in HSCT and graft rejection in SOT. The long-term use of these drugs is associated with a high risk of infections, but there are also evidences of their specific interference with virus infection. The antiviral activity of immunosuppressors commonly used in the clinical practice in SOT and HSCT recipients has been evaluated in vitro to determine whether their use could be associated with less risk of HAdV and HCMV infection...

BACKGROUND: The diagnosis of tuberculosis (TB) in solid organ transplant (SOT) recipients presents challenges that may lead to treatment delay. These include atypical clinical presentations, increased likelihood of negative tuberculin skin test or/and interferon-gamma release assays, and negative sputum smear results despite active disease. The treatment poses challenges due to pharmacokinetic interactions, allograft-related toxicity, and inadequate immune response. CASE REPORT: We report the case of a 70-year-old man after kidney transplantation in 2012...

OBJECTIVE: Solid organ transplant (SOT) recipients have a poorer SARS-CoV-2 vaccine response and higher risk for COVID-19-associated complications. However, there is no consensus on the current management of COVID-19 and data on persistent COVID-19 rates in SOT recipients are lacking. METHODS: An electronic survey concerning the management of COVID-19 in SOT recipients was distributed among all members of the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) Study Group for Infections in Compromised Hosts (ESGICH) and of the European Society for Organ Transplantation (ESOT)...

Eucalyptus cinerea is an evergreen tree in the Myrtaceae. It is native to southern and eastern New South Wales and northern and eastern Victoria, Australia. It was introduced into China in the 1980s (Silva et al. 2011). Because of its unique shape, flexible stems, and rapid growth characteristics, it is widely used in the pulp industry and in decorative materials such as flower bouquets. In July 2022, 5- to 10-year-old E. cinerea showing symptoms of dehydration, withering and yellowing leaves, were found in forests and nurseries in Kunming and Songming, China...

OBJECTIVE: Determine the postoperative outcomes in solid-organ transplant (SOT) patients undergoing operative treatment of lower extremity fractures. METHODS: Design: Retrospective comparative study. SETTING: Academic Level 1 Trauma center. PATIENT SELECTION CRITERIA: Patients who underwent SOT and operative treatment for lower extremity fracture from 2013-2021 were identified, excluding pathologic fractures.Outcome Measures and Comparisons: postoperative complications, length of stay, time to death, 90-day and 1-year readmission rates, readmission causes, discharge location, and immunosuppressive regiments...

Epstein-Barr virus (EBV) infection and EBV-associated post-transplant lymphoproliferative disorder (EBV/PTLD) is one of the most devastating complications occurring in pediatric solid organ transplant (SOT) recipients. Observations of SOT recipients undergoing serial EBV monitoring to inform reduction of immune suppression to prevent EBV-/PTLD has identified patients who maintain chronic high EBV load (CHL) in their blood. The CHL carrier state has been seen more commonly in pediatric compared to adult transplant recipients...

BACKGROUND: Cytomegalovirus (CMV) infections are common opportunistic infections in solid organ transplants (SOT) with increased health care resource USE and costs. Costs are further increased with ganciclovir-resistance (GR). This study aimed to evaluate the real-world impact of conversion to oral step-down therapy on duration of foscarnet and hospital length of stay (LOS) for treatment of GR-CMV infections in SOT. METHODS: This study included adult recipients of kidney or lung transplants who received foscarnet for genotypically documented GR-CMV while admitted at the University of Wisconsin Hospital from October 1, 2015, to January 31, 2022...

PURPOSE OF REVIEW: Human cytomegalovirus (CMV) continues to be the most important infectious complication following solid organ transplantation (SOT). RECENT FINDINGS: Universal prophylaxis and preemptive therapy are the most adopted strategies for prevention of CMV disease globally. Prophylaxis with valganciclovir is the most widely used approach to CMV prevention, however leukopenia and late onset CMV disease after discontinuation of prophylaxis requires new strategies to prevent this complication...

This is a cross-sectional study examining kinetics and durability of immune response in children with solid organ transplants (SOTs) who had COVID-19 disease between November 2020 through June 2022, who were followed for 60-days at a single transplant center. Blood was collected between 1-14 (acute infection), and 15-60 days of a positive PCR (convalescence). SOT children with peripheral blood mononuclear cells (PBMC) cryopreserved before 2019 were non-infected controls (ctrls). PBMCs stimulated with 15-mer peptides from spike protein and anti-CD49d/anti-CD28...

SUMMARYThere is a growing need for solid organ transplantation (SOT) for people living with human immunodeficiency virus (HIV). With the advent of antiretroviral therapy, people living with HIV are experiencing increased life expectancies and are, therefore, developing more comorbidities, including end-stage organ disease. In cases of advanced organ failure, SOT is often the best therapeutic option to improve quality of life and overall survival. As organ shortages persist, transplantation of organs from donors with HIV to recipients with HIV has become a potential therapeutic option...

Cryptococcosis is the third most commonly occurring invasive fungal disease in solid organ transplant recipients (SOT). It is caused by encapsulated yeast, Cryptococcus species, predominantly Cryptococcus neoformans and Cryptococcus gattii. Though kidney transplant recipients are at the lowest risk of cryptococcosis when compared to other solid organ transplant recipients such as lung, liver or heart, still this opportunistic infection causes significant morbidity and mortality in this subset of patients. Mortality rates with cryptococcosis range from 10%-25%, while it can be as high as 50% in SOT recipients with central nervous system involvement...

BACKGROUND: Cytomegalovirus (CMV) infections among hematopoietic stem cell transplant (HSCT) and solid organ transplant (SOT) recipients impose a significant health care resource utilization (HCRU)-related economic burden. Maribavir (MBV), a novel anti-viral therapy (AVT), approved by the United States Food and Drug Administration for post-transplant CMV infections refractory (with/without resistance) to conventional AVTs has demonstrated lower hospital length of stay (LOS) versus investigator-assigned therapy (IAT; valgancilovir, ganciclovir, foscarnet, or cidofovir) in a phase 3 trial (SOLSTICE)...

INTRODUCTION: Solid organ transplant (SOT) has an anticipated higher risk of penile prosthesis (PP) complications related to immunosuppression and surgical approach post-SOT. It is still not determined if PP surgery in the SOT population incurs these same higher risks. OBJECTIVES: To observe differences in intra- and postoperative PP complications between SOT and non-SOT cases from the TriNetX US Collaborative Network, a large real-world database of deidentified patient data from 56 health care organizations within the United States...
