New biomarkers are required to detect acute rejection (AR) in kidney transplant recipients (KTRs) to avoid invasive kidney biopsies. We assess whether a 5-gene panel (DUSP1; NKTR; PBEF1; MAPK9; and PSEN1) in whole blood samples that has previously been shown to identify AR in a paedriatric KTR population is able to distinguish AR in a UK population of adult Caucasian KTR patients.

Abstract Background and Aims Both under and over-dosing of tacrolimus may compromise clinical outcomes by exposing patients to either the risks of graft rejection or adverse events (AEs) associated with immunosuppressive therapy. This study is designed to compare the clinical follow-up of our kidney transplant recipients receiving once-daily, prolonged-release (PR-T; Advagraf) and twice-daily, immediate-release (IR-T; Prograf) tacrolimus in the early posttransplant period. Method This randomized study included 78 de novo, adult kidney transplant recipients to PR-T 0.15 mg/kg/day (Group I=39) and IR-T 0.15 mg/kg/day (Group II=39) for seven days in the posttransplant period. Demographic features and clinical parameters regarding levels of whole blood tacrolimus and serum creatinine were compared between the two groups. Presence of acute rejection and AEs were investigated. Dose adjustments were permitted to target a pre-defined therapeutic range based on measured trough blood concentrations in all patients. SPSS 15 for Windows was used for statistical analysis. Results None of the patients suffered from acute rejection and there were no AEs in the early posttransplant period. However, Group II patients were found to have higher whole blood tacrolimus levels on the posttransplant 1st, 4th and 7th days (p=0.02, p=0.009 and p=0.013 respectively). Also serum creatinine levels were significantly increased in Group II patients on the posttransplant 7th day (p=0.02). Conclusion Prolonged release tacrolimus seems promising in preventing acute transplant rejection with adequate blood levels, as well as making it possible to avoid the interindividual variation in absorption and early calcineurin inhibitor toxicity.

SummaryWe analysed whether the factor V Leiden mutation – the most common hereditary predisposing factor for venous thrombosis – is associated with early and long-term graft dysfunction after kidney transplantation in 394 Caucasian kidney transplant recipients. The presence of factor V Leiden mutation was identified by allele specific PCR. The prevalence of the factor V Leiden mutation was compared to 32216 unselected neonates. The prevalence of the factor V Leiden mutation (GA genotype) was similar in 394 kidney transplant recipients and 32216 neonates. The frequency of known factors predicting long-term graft function were similar in patients with the GA genotype and with the normal factor V gene (GG genotype). The GA genotype was associated with the occurrence of no primary graft function (risk: 2.87; 95% confidence interval: 1.01-8.26; p < 0.05), the number of dialysis after transplantation in patients with no primary graft function until graft function (7.5 ± 2.06 dialysis in GA patients; 4.2 ± 0.36 dialyses in GG patients; p < 0.05), and the risk for at least one acute rejection episode (risk: 3.83; 95% confidence interval: 1.38-10.59; p < 0.02). The slope of 1/creatinine per year was significantly lower in patients with the GA genotype (GA patients: – 0.0204 ± 0.008 dl/mg per year; GG patients: 0.0104 ± 0.004 dl/mg per year; p < 0.02). The annual enhancement of the daily protein excretion rate was elevated in patients with the GA genotype (GA patients: 38.5 ± 16.6 mg/24 h per year; GG patients: 4.9 ± 4.4 mg/24 h per year; p < 0.02). Our study showed that the factor V Leiden mutation is associated with the occurrence of delayed graft function, acute rejection episodes and chronic graft dysfunction after kidney transplantation.

Background: Antiretroviral therapy (ART) poses challenging drug-drug interactions with immunosuppressant agents in transplant recipients.  We aimed to determine the impact of specific antiretroviral regimens in clinical outcomes of HIV+ kidney transplant recipients. Methods: A single-center, retrospective cohort study was conducted at a large academic center. Subjects included 58 HIV- to HIV+ adult, first-time kidney transplant patients. The main intervention was ART regimen used after transplantation.  The main outcomes assessed at one- and three-years were: patient survival, death-censored graft survival, and biopsy-proven acute rejection; we also assessed serious infections within the first six months post-transplant. Results: Patient and graft survival at three years were both 90% for the entire cohort. Patients receiving protease inhibitor (PI)-containing regimens had lower patient survival at one and three years than patients receiving PI-sparing regimens: 85% vs. 100% (p=0.06) and 82% vs. 100% (p=0.03), respectively. Patients who received PI-containing regimens had twelve times higher odds of death at 3 years compared to patients who were not exposed to PIs (odds ratio, 12.05; 95% confidence interval, 1.31-1602; p=0.02).  Three-year death-censored graft survival was lower in patients receiving PI vs. patients on PI-sparing regimens (82 vs 100%, p=0.03). Patients receiving integrase strand transfer inhibitors-containing regimens had higher 3-year graft survival. There were no differences in the incidence of acute rejection by ART regimen. Individuals receiving PIs had a higher incidence of serious infections compared to those on PI-sparing regimens (39 vs. 8%, p=0.01). Conclusions: PI-containing ART regimens are associated with adverse outcomes in HIV+ kidney transplant recipients.
