Kidney Function Decline

Carnosine affords protection against oxidative and carbonyl stress, yet high concentrations of the carnosinase-1 enzyme may limit this. We recently reported that high urinary carnosinase-1 is associated with kidney function decline and albuminuria in patients with chronic kidney disease. We prospectively investigated whether urinary carnosinase-1 is associated with a high risk for development of late graft failure in kidney transplant recipients (KTRs). Carnosine and carnosinase-1 were measured in 24 h urine in a longitudinal cohort of 703 stable KTRs and 257 healthy controls. Cox regression was used to analyze the prospective data. Urinary carnosine excretions were significantly decreased in KTRs (26.5 [IQR 21.4–33.3] µmol/24 h versus 34.8 [IQR 25.6–46.8] µmol/24 h; p < 0.001). In KTRs, high urinary carnosinase-1 concentrations were associated with increased risk of undetectable urinary carnosine (OR 1.24, 95%CI [1.06–1.45]; p = 0.007). During median follow-up for 5.3 [4.5–6.0] years, 84 (12%) KTRs developed graft failure. In Cox regression analyses, high urinary carnosinase-1 excretions were associated with increased risk of graft failure (HR 1.73, 95%CI [1.44–2.08]; p < 0.001) independent of potential confounders. Since urinary carnosine is depleted and urinary carnosinase-1 imparts a higher risk for graft failure in KTRs, future studies determining the potential of carnosine supplementation in these patients are warranted.

Background: The implications of venous thromboembolism (VTE) for morbidity and mortality in kidney transplant recipients are not well described. Methods: We conducted a retrospective study using linked healthcare databases in Ontario, Canada to determine the risk and complications of VTE in kidney transplant recipients from 2003 to 2013. We compared the incidence rate of VTE in recipients (n = 4,343) and a matched (1:4) sample of the general population (n = 17,372). For recipients with evidence of a VTE posttransplant, we compared adverse clinical outcomes (death, graft loss) to matched (1:2) recipients without evidence of a VTE posttransplant. Results: During a median follow-up of 5.2 years, 388 (8.9%) recipients developed a VTE compared to 254 (1.5%) in the matched general population (16.3 vs. 2.4 events per 1,000 person-years; hazard ratio [HR] 7.1, 95% CI 6.0-8.4; p < 0.0001). Recipients who experienced a posttransplant VTE had a higher risk of death (28.5 vs. 11.2%; HR 4.1, 95% CI 2.9-5.8; p < 0.0001) and death-censored graft loss (13.1 vs. 7.5%; HR 2.3, 95% CI 1.4-3.6; p = 0.0006) compared to matched recipients who did not experience a posttransplant VTE. Conclusions: Kidney transplant recipients have a sevenfold higher risk of VTE compared to the general population with VTE conferring an increased risk of death and graft loss.

BackgroundThe novel SARS-CoV-2 virus has caused a global pandemic of coronavirus disease 2019 (COVID-19). Although immunosuppressed individuals are thought to be at an increased risk of severe disease, little is known about their clinical presentation, disease course, or outcomes.MethodsWe report 15 kidney transplant recipients from the Columbia University kidney transplant program who required hospitalization for confirmed COVID-19, and describe their management, clinical course, and outcomes.ResultsPatients presented most often with a fever (87%) and/or cough (67%). Initial chest x-ray most commonly showed bilateral infiltrates, but 33% had no acute radiographic findings. Patients were managed with immunosuppression reduction and the addition of hydroxychloroquine and azithromycin. Although 27% of our patients needed mechanical ventilation, over half were discharged home by the end of follow-up.ConclusionsKidney transplant recipients with COVID-19 have presentations that are similar to that of the general population. Our current treatment protocol appears to be associated with favorable outcomes, but longer follow-up of a larger cohort of patients is needed.

Abstract Background and Aims BK virus nephropathy occurs in up to 10% of kidney transplant recipients and can result in graft loss. The reactivation of BK virus is largely asymptomatic, and routine surveillance especially in the first 12-24 months after transplant is necessary for early recognition and intervention. Reduced immunosuppression and antiviral treatment in the early stages may be effective in stopping BK virus replication. This study is designed to investigate the effect of management in immunosuppressive therapy on BK virus titers and graft functions in our kidney transplant group. Method A total of 370 kidney transplant recipients between the ages of 18-69 years and receiving a triple immunosuppressive therapy (Tacrolimus+Mycophenoloic Acid+Prednisolone) were included in the study. Demographic characteristics, BK virus titers, serum creatinine and immunosuppressive drug (Tacrolimus, Everolimus) levels were measured at regular intervals in the first 24 months. Among these patients 43 of them were found to have BK virus positivity. At the time of the detection of BK virus positivity, patients were divided into three groups regarding the change in the immunosuppressive protocols: Group I: Tacrolimus + Everolimus + Prednisolone, Group II: Everolimus + Prednisolone, Group III: Tacrolimus + Prednisolone. BK virus titers and graft functions of all three groups were compared with each other. SPSS 15 for Windows was used for statistical analysis. Results The mean age of the patients was 45.3 years, and the mean duration of transplantation was 16.3 months at the time of the BK virus positivity. During the follow-up, mean Tacrolimus levels were found to be in their highest value (14.1 ng/mL) in the posttransplant three months while BK virus titer reached the highest value (1.1x106 copies/ml) in the posttransplant seven to nine months. Increased creatinine values two months after BK virus positivity were strongly correlated (p = 0.02, p = 0.008, p = 0.05, p = 0.002 at 6th, 9th, 12th and 24th months, respectively). A significant decrease in BK virus titers was observed in all three groups due to reductions in immunosuppressive treatment protocol (p = 0.005, p = 0.003, p = 0.028, in groups I, II, III respectively). Conclusion Our study favors the benefits of the prospective screening for BK virus to identify early viral replication, permit intervention, and prevent progression to nephropathy or allograft loss. The best studied treatment for BK viremia and nephropathy is careful reduction of immunosuppression
