Statin use is associated with prolonged survival of renal transplant recipients.

ABSTRACT: The efficacy of statins for the prevention of cardiovascular events is well established in the general population but remains unknown in renal transplant recipients. In this study, the association of statin use with patient and graft survival was investigated in a cohort of 2041 first-time recipients of renal allografts between 1990 and 2003. Multivariable Cox regression demonstrated that statin use was independently associated with lower mortality rates. Twelve-year survival rates were 73% for statin users and 64% for nonusers (P = 0.055). The adjusted hazard ratio for all-cause mortality associated with statin use was 0.64 (95% confidence interval 0.48 to 0.86). Graft survival rates during the same time period were 76% for statin users and 70% for nonusers (P = 0.055). The adjusted hazard ratio for graft survival associated with statin use was 0.76 (95% confidence interval 0.55 to 1.04). Results from marginal structural models were virtually identical. In summary, statin use was associated with prolonged patient survival, but no difference in graft survival was detected. Although these results are encouraging, a definitive causal relationship can be determined only from randomized clinical trials.

Project description:BackgroundTransplant glomerulopathy, a common glomerular lesion observed after kidney transplant that is associated with poor prognosis, is not a specific entity but rather the end stage of overlapping disease pathways. Its heterogeneity has not been precisely characterized to date.MethodsOur study included consecutive kidney transplant recipients from three centers in France and one in Canada who presented with a diagnosis of transplant glomerulopathy (Banff cg score ≥1 by light microscopy), on the basis of biopsies performed from January of 2004 through December of 2014. We used an unsupervised archetype analysis of comprehensive pathology findings and clinical, immunologic, and outcome data to identify distinct groups of patients.ResultsAmong the 8207 post-transplant allograft biopsies performed during the inclusion period, we identified 552 biopsy samples (from 385 patients) with transplant glomerulopathy (incidence of 6.7%). The median time from transplant to transplant glomerulopathy diagnosis was 33.18 months. Kidney allograft survival rates at 3, 5, 7, and 10 years after diagnosis were 69.4%, 57.1%, 43.3%, and 25.5%, respectively. An unsupervised learning method integrating clinical, functional, immunologic, and histologic parameters revealed five transplant glomerulopathy archetypes characterized by distinct functional, immunologic, and histologic features and associated causes and distinct allograft survival profiles. These archetypes showed significant differences in allograft outcomes, with allograft survival rates 5 years after diagnosis ranging from 88% to 22%. Based on those results, we built an online application, which can be used in clinical practice on the basis of real patients.ConclusionsA probabilistic data-driven archetype analysis approach applied in a large, well defined multicenter cohort refines the diagnostic and prognostic features associated with cases of transplant glomerulopathy. Reducing heterogeneity among such cases can improve disease characterization, enable patient-specific risk stratification, and open new avenues for archetype-based treatment strategies and clinical trials optimization.
