The association of genetic variants with hepatic steatosis in patients with genotype 1 chronic hepatitis C infection.

ABSTRACT:

Background

Single-nucleotide polymorphisms (SNPs) in the IL28B and PNPLA3 gene regions have been associated with hepatic steatosis in genotype 1 (G1) chronic HCV infection but their clinical impacts remain to be determined.

Aim

We sought to validate these associations and to explore their impact on treatment response to peginterferon and ribavirin therapy.

Methods

A total of 972 G1 HCV-infected Caucasian patients were genotyped for the SNPs rs12979860 (IL28B) and rs2896019 (PNPLA3). Multivariable analysis tested IL28B and PNPLA3 for association with the presence of any steatosis (>0 %); clinically significant steatosis (>5 %); steatosis severity (grade 0-3/4); and the interacting associations of the SNPs and hepatic steatosis to sustained viral response (SVR).
