Summary: Human cytomegalovirus (HCMV) infection is associated with renal allograft failure. CMV promotes allograft damage via cytokine-mediated Th1/17 cell recruitment. Pharmacologic inhibition of the Th17 cell signature cytokine, IL-17A, ameliorates CMV-associated allograft damage.

Summary: This study found that the risk of cytomegalovirus (CMV) transmission in solid organ transplant recipients is influenced by the type of allograft, and that the use of antiviral prophylaxis may not alter the transmission risk. Additionally, factors related to the donor may also impact the transmission outcomes.

Summary: This study aimed to compare the outcomes of kidney transplant recipients and non-transplant patients in terms of survival and severity of COVID-19. The findings suggest that the severity of COVID-19 in kidney transplant recipients is related to their associated comorbidities and not to chronic immunosuppression.

Summary: Desensitization for incompatible living donor kidney transplantation increases the risk of infections, especially in highly desensitized recipients, leading to prolonged hospitalization and graft loss. Strategies are needed to protect patients from recurrent infections and extend the survival benefit of ILDKT.

Summary: Cryptococcus gattii infection, a rare but severe pulmonary disease and meningoencephalitis, recently emerged in the southeastern United States. An organ transplant-related outbreak involved an immunosuppressed donor and three recipients, with positive CrAg testing in the donor. Two recipients developed severe infection, resulting in one death and one survival following treatment for cryptococcal meningitis. The outbreak highlights the importance of considering cryptococcosis in patients with clinical findings suggestive of CNS pathology and the potential benefit of routine pre-transplant donor CrAg screening.

Summary: The study on 148 kidney transplant recipients showed that the mRNA SARS-CoV-2 vaccine elicited either cellular or humoral response in 65.0% of the patients. Approximately 20.9% of patients were considered to have prior immunization against SARS-CoV-2, while 79.1% were deemed naïve to the virus.

Summary: A systematic review of randomized and observational studies from 2013-2023 indicated that antiviral preemptive therapy initiated at cytomegalovirus viral load thresholds between 2 and 3 log10 IU/mL had comparable cytomegalovirus disease rates. Thus, viral thresholds within this range appeared to effectively safeguard patients who did not receive prophylaxis.

Summary: Trials of short-course DAAs for HCV transmission in kidney transplant recipients showed promising results in reducing transmission rates, with all cases of transmission achieving sustained virologic response after full-course therapy. However, cost and access to treatment remain potential barriers to real-world application.

Summary: Primary CMV infection/reactivation in kidney transplant recipients may lead to rejection and mortality. T follicular helper cells (TFH) could play a protective role against CMV, with circulatory TFH (cTFH) levels affecting CMV infection rates. Monitoring cTFH levels pre- and post-transplant could improve CMV risk stratification and benefit high-risk patients.

Summary: Kidney transplant recipients show a lower anti-SARS-CoV-2 IgG seroprevalence compared to healthcare workers, with those who had SARS-CoV-2 infection being younger and more likely to receive CNI-based immunosuppression. Interestingly, kidney transplant recipients had higher levels of anti-SARS-CoV-2 IgG antibodies compared to healthcare workers, with the presence of moderate to severe symptoms being the main factor affecting IgG levels in kidney transplant recipients.

Summary: This study systematically assessed the definition and prognostic implications of HLA incompatibility in transplant outcomes, finding heterogeneity in the definition and incomplete reporting of variables. The risk of bias in studies examining the association between death-censored graft failure and HLA incompatibility was high. Therefore, optimizing HLA compatibility assessment and standardizing the reporting of variables are necessary for improving transplant outcomes and promoting international collaboration.

Summary: Well-selected patients with kidney disease and diabetes mellitus who undergo simultaneous kidney-pancreas transplantation often experience improved quality of life and long-term survival. Frailty has become increasingly important in the pancreas transplant candidate and recipient populations. This review discusses the risk factors, measurement, outcomes, and interventions related to frailty in pancreas transplant patients.

Summary: Organ procurement organizations (OPOs) in the United States face barriers in obtaining kidney biopsies and pumping due to lack of available staff and transportation. Moreover, the new allocation system has worsened transportation challenges, increased provisional acceptances of kidneys, and communication challenges with transplant centers, and worsened the efficiency of organ allocation. OPOs suggest making transplant centers more accountable, developing reliable transportation options, and removing the requirement for national sharing.

Summary: Annotation of biomedical entities with ontology classes facilitates semantic analysis and utilization of background knowledge. We have developed a new tool called Klarigi, which introduces multiple scoring heuristics to identify compositional and discriminatory classes for annotated entity groups. Klarigi utilizes semantic inference, classification, and significance testing to provide characteristic and explanatory explanations for biomedical datasets, offering a distinct perspective compared to traditional enrichment methods.

Summary: This article investigates the variation in attitudes and management of delayed graft function (DGF) in the field of kidney transplantation, revealing that DGF occurs at a rate of 20%-40% in most centers. Despite its commonality, only half of the centers reported having an established protocol to manage DGF. Kidney allograft biopsies were the only consistent management strategy observed, although the use of machine perfusion was also favored. The research suggests that sharing best practices, redefining terminology, establishing DGF dialysis guidelines, and improving access to machine perfusion across OPOs may help reduce discard and improve utilization of kidneys at risk for DGF.

Summary: In October 2021, the American Society of Transplantation (AST) held a virtual consensus conference to address barriers preventing the expansion of living donor liver transplantation (LDLT) in the United States. A multidisciplinary group of experts identified financial implications on donors, crisis management, policies and regulations, and ethical considerations as significant barriers. They proposed strategies to overcome these barriers and highlighted the importance of donor safety and the need for appropriate crisis management plans in transplant programs.
