Cytomegalovirus (CMV) is a β-herpesvirus. CMV infections are a common complication contributing to morbidity and mortality after liver transplantation. Among organ transplant recipients, CMV can reactivate from latency during the first 6 months. This prospective study performed from February 2008 to December 2009 examined liver transplant recipients during the first 6 months. Two methods were performed to detect CMV infections: antigenemia (AGM) and nested (PCR). Ninety-four patients, including 72 men (76.6%) and 22 women (23.4%) underwent liver transplantation during this period. We analyzed 575 samples including 465 for AGM and PCR. Forty-three (9.25%) showed positive AGM as detected 2 to 179 days posttransplantation with a mean of 50 days and a median of 35 days, and 93/465 (20%) showed positive PCR at 0 to 186 days posttransplantation with a mean of 31 days and a median of 38 days. Among the 43 antigenemia patients, 38 samples were positive for up to 5 cells 18 of which were PCR-positive. Five samples were positive with more than 5 cells, including 3 that were PCR-positive. Only 4.51% had AGM and were PCR-positive in the same sample. Despite only 9.25% (43/465) showing AGM, the current study suggested the utility of routine monitoring to detect early CMV infection among liver transplantation patients seeking to reduce morbidity and mortality.

Background: The 2023 IPNA guidelines recommended a 12-h mycophenolic acid (MPA) area under the curve (AUC) estimation for managing pediatric nephrotic syndrome and MPA AUC > 50 mg * h/L for an optimal therapeutic response to mycophenolate mofetil (MMF). The IPNA guidelines endorsed two limited AUC formulae based on three-point MPA measurements to predict 12-h MPA AUC. The relative performance of these two limited AUC formulae has not been tested.

Background: Early allograft dysfunction (EAD) affects outcomes in liver transplantation (LT). Existing risk models developed for deceased-donor LT depend on posttransplant factors and fall short in living-donor LT (LDLT), where pretransplant evaluations are crucial for preventing EAD and justifying the donor's risks.
Methods: This retrospective study analyzed data from 2944 adult patients who underwent LDLT at 17 centers between 2016 and 2020.

Background: It remains unclear whether physicians should accept transplantation offers for candidates with a positive SARS-CoV-2 reverse transcription polymerase chain reaction test due to the potential risk of severe infection after initiating immunosuppressive therapy.
Methods: A multicenter observational study was conducted in 19 French solid organ transplantation units. Patients on the waiting list for liver or kidney transplants who had a positive SARS-CoV-2 reverse transcription polymerase chain reaction nasopharyngeal swab at the time of transplantation were recorded.

In the field of organ transplantation, the accurate assessment of donor organ quality is necessary to efficient organ allocation and to informed consent for recipients. A common approach to organ quality assessment is the development of statistical models that accurately predict post-transplant survival by integrating multiple characteristics of the donor and allograft. Despite the proliferation of predictive models across many domains of medicine, many physicians may have limited familiarity with how these models are built, the assessment of how well models function in their population and the risks of a poorly performing model.

Purpose Of The Review: Calcineurin inhibitors (CNIs) are central to immunosuppression in kidney transplantation (KT), improving short-term outcomes but falling short in enhancing long-term outcomes due to cardiovascular, metabolic, and renal complications. Belatacept, an FDA-approved costimulation blocker, offers a less toxic alternative to CNIs but is limited by its intravenous administration and reduced efficacy in high-immunological-risk patients.
Recent Findings: Emerging therapies target more specific pathways to improve efficacy and accessibility.
