    Abstract:
    BACKGROUND: Cardiovascular disease is the leading cause of death in patients with chronic kidney disease (CKD). Single nucleotide polymorphisms (SNPs) in ANRIL gene have been associated with higher cardiovascular morbidity and mortality in general population. The main objective was to ascertain whether ANRIL polymorphisms could identify risk of major adverse cardiovascular event (MACE) in patients starting on hemodialysis (HD). METHODS: This was a prospective observational cohort study. 284 CKD patients starting on HD were included in the study and followed until achievement of the primary end-point (MACE) or end of the study. All patients were genotyped for four ANRIL SNPs (rs10757278, rs4977574, rs10757274 and rs6475606). Kaplan-Meier curves and multivariate Cox survival analyses, together with multiple logistic regression were used to analyze the association between ANRIL SNPs and MACE. RESULTS: We found that ANRIL SNP rs10757278 was a representative SNP of a strong linkage disequilibrium block and showed significant genotypic associations with MACE in hemodialysis patients. Homozygous patients for the risk allele (GG) showed 2.17 (1.05-4.49) fold increased risk of MACE during hemodialysis than carriers of the protective allele (AA or AG). Diabetes mellitus was a strong enhancer of this effect. CONCLUSIONS: Our results indicate that ANRIL polymorphisms may confer risk to development of MACE in incident patients on hemodialysis.
