Characterization of Clinical and Genetic Risk Factors Associated with Dyslipidemia after Kidney Transplantation

Abstract

We determined the prevalence of dyslipidemia in a Japanese cohort of renal allograft recipients and investigated clinical and genetic characteristics associated with having the disease. In total, 126 patients that received renal allograft transplants between February 2002 and August 2011 were studied, of which 44 recipients (34.9%) were diagnosed with dyslipidemia at 1 year after transplantation. Three clinical factors were associated with a risk of having dyslipidemia: a higher prevalence of disease observed among female than male patientsP=0.021and treatment with high mycophenolate mofetilP=0.012and prednisoloneP=0.023doses per body weight at 28 days after transplantation. The genetic association between dyslipidemia and 60 previously described genetic polymorphisms in 38 putative disease-associated genes was analyzed. The frequency of dyslipidemia was significantly higher in patients with the glucocorticoid receptor (NR3C1)Bcl1G allele than in those with the CC genotypeP=0.001. A multivariate analysis revealed that theNR3C1 Bcl1G allele was a significant risk factor for the prevalence of dyslipidemia (odds ratio = 4.6; 95% confidence interval = 1.8–12.2). These findings may aid in predicting a patient’s risk of developing dyslipidemia.
