Relationship of TRIM5 and TRIM22 polymorphisms with liver disease and HCV clearance after antiviral therapy in HIV/HCV coinfected patients

2016 Journal of translational medicine 14;(257)

BACKGROUND AND AIMS: TRIM5 and TRIM22 are restriction factors involved in innate immune response and exhibit anti-viral activity. Single nucleotide polymorphisms (SNPs) at TRIM5 and TRIM22 genes have shown to influence several viral infections such as human immunodeficiency virus (HIV), hepatitis B, as well as measles and rubella vaccination. The aim of this study is to analyze whether TRIM5 and TRIM22 polymorphisms are associated with liver fibrosis inflammation-related biomarkers and response to pegylated-interferon-alpha plus ribavirin (pegIFNalpha/RBV) therapy in HIV/hepatitis C virus (HCV) coinfected patients. METHODS: A retrospective study was performed in 319 patients who started pegIFNalpha/RBV therapy. Liver fibrosis stage was characterized in 288 patients. TRIM5 rs3824949 and TRIM22 polymorphisms (rs1063303, rs7935564, and rs7113258) were genotyped using the GoldenGate assay. The primary outcomes were: a) significant liver fibrosis (>/=F2) evaluated by liver biopsy or transient elastography (liver stiffness values >/=7.1 Kpa); b) sustained virological response (SVR) defined as no detectable HCV viral load (
