Phenylethanolamine N-methyltransferase gene polymorphisms and adverse outcomes in acute kidney injury.

ABSTRACT:

Background/aims

The catecholaminergic pathway is important in the physical stress response; however, its role is not well understood in acute kidney injury (AKI). We studied single nucleotide polymorphisms (SNPs) of phenylethanolamine N-methyltransferase (PNMT), the terminal enzyme of the catecholaminergic pathway, and their association with adverse outcomes in AKI.

Methods

We performed a case-control study of 961 Caucasian subjects (194 with AKI and 767 controls). The PNMT promoter G-161A (rs876493) and coding A+1543G (rs5638) SNPs were genotyped and haplotypes generated. The outcomes of interest were the development of AKI, in-hospital mortality, dialysis requirement, oliguria, and hemodynamic shock. Urine catecholamines were measured in cases to explore genotype-phenotype
