CD4 T cell lymphopenia predicts mortality from Pneumocystis pneumonia in kidney transplant patients.

Background: Pneumocystis jirovecii pneumonia (PcP) remains a life-threatening opportunistic infection after solid organ transplantation, even in the era of Pneumocystis prophylaxis. The association between risk of developing PcP and low CD4 T cell counts has been well established. However, it is unknown whether lymphopenia in the context of post-renal transplant PcP increases the risk of mortality.

How to Prevent Renal Cachexia? A Clinical Randomized Pilot Study Testing Oral Supplemental Nutrition in Hemodialysis Patients With and Without Human Immunodeficiency Virus Infection.

Objective: End-stage renal disease associates with catabolism and sarcopenia. Hypothetically, peroral supplemental nutrition over 6 months prevents catabolism in hemodialysis patients.

Design: Prospective randomized pilot study (ClinicalTrials.

Pretransplant human leukocyte antigen antibodies detected by single-antigen bead assay are a risk factor for long-term kidney graft loss even in the absence of donor-specific antibodies.

Clinical relevance of ELISA- and single-antigen bead assay (SAB)-detected pretransplant HLA antibodies (SAB-HLA-Ab) for kidney graft survival was evaluated retrospectively in 197 patients transplanted between 2002 and 2009 at the University Clinic Frankfurt. Having adjusted for retransplantation and delayed graft function, a significantly increased risk for death-censored graft loss was found in patients with pretransplant SAB-HLA-Ab [HR: 4.46; 95% confidence interval (CI): 1.

Transcatheter aortic valve implantation improves outcome compared to open-heart surgery in kidney transplant recipients requiring aortic valve replacement.

Background: Cardiovascular disease is the most frequent cause of mortality for kidney transplant recipients. Open heart surgery has particularly high mortality and morbidity. As an alternative to traditional aortic valve replacement (AVR) for patients with high-grade aortic stenosis, transcatheter aortic valve implantation (TAVI) was developed as an innovative therapy for patients considered at high surgical risk.

Human pregnane X receptor genotype of the donor but not of the recipient is a risk factor for delayed graft function after renal transplantation.

Delayed graft function (DGF) is an important complication in renal transplantation, contributing significantly to decrease in long-term allograft survival. In addition to donor- and recipient-related risk factors such as immunosuppression, altered renal excretion of xenobiotics by membrane transporters may influence DGF. Using DNA samples from recipients and donors, we assessed the impact on DGF of genetic variants in P-glycoprotein (ABCB1), multidrug resistance protein 2 (ABCC2), and the nuclear pregnane X receptor (PXR/NR1I2), which regulates the transcription of enzymes and transporters.
