BACKGROUND The CXCL9, CXCL10 and CXCL11 (CXCL9-11) chemokines play a critical role in eradication of hepatitis C virus (HCV), although HCV-specific immunity often fails to eradicate the HCV, allowing the chronicity of hepatitis C. OBJECTIVE To examine the association between CXCL9-11 polymorphisms and the sustained virological response (SVR) following(More)
BACKGROUND The adiponectin (ADIPOQ) rs2241766 polymorphism is related to metabolic abnormalities. The aim of this study was to evaluate the association of the ADIPOQ rs2241766 polymorphism with serum dyslipidemia and insulin resistance (IR) in human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients. METHODS We carried out a(More)
OBJECTIVE To analyze the relationship of SLC30A8 rs13266634 polymorphism with insulin resistance and dyslipidemia in HIV/hepatitis C virus (HCV)-coinfected patients. DESIGN Cross-sectional study in 260 HIV/HVC-coinfected patients. METHODS SLC30A8 polymorphisms were genotyped by GoldenGate assay. Genetic data were analyzed under the dominant inheritance(More)
BACKGROUND  Hepatic venous pressure gradient (HVPG) is the best indicator of prognosis in patients with compensated cirrhosis. We compared HVPG and transient elastography (TE) for the prediction of liver-related events (LREs) in patients with hepatitis C virus (HCV)-related cirrhosis with or without human immunodeficiency virus (HIV) coinfection. METHODS(More)
The multisubunit RNA polymerase (RNAP) in bacteria consists of a catalytically active core enzyme (alpha(2)beta beta'omega) complexed with a sigma factor that is required for promoter-specific transcription initiation. During early elongation the stability of interactions between sigma and core decreases, in part because of the nascent RNA-mediated(More)
BACKGROUND We compared the prognostic value of liver biopsy (LB) and FIB-4 index in patients with human immunodeficiency virus (HIV)/hepatitis C virus (HCV) coinfection. METHODS We studied patients from the Grupo de Estudio del SIDA 3603 study cohort, in whom fibrosis was evaluated at baseline using both LB (Metavir score) and FIB-4 index. We assessed(More)
Interleukin-7 (IL-7) is a critical factor in maintaining or inducing effective antiviral CD4+ and CD8+ T-cell responses. The aim of this study was to examine the association of interleukin-7 receptor-α (IL7RA) polymorphisms with a sustained virologic response (SVR) after hepatitis C virus (HCV) therapy with pegylated interferon-alpha plus ribavirin(More)
OBJECTIVE To analyze the association between patatin-like phospholipase domain-containing 3 gene (PNPLA3) rs738409 polymorphism and severity of liver disease in HIV/hepatitis C virus-coinfected patients. METHODS We performed a cross-sectional study of 215 patients who underwent a liver biopsy. PNPLA3 rs738409 polymorphism was genotyped using GoldenGate(More)
BACKGROUND CXCR3A-associated chemokines (CXCL9-11) are implicated in the pathogenesis of hepatitis C virus (HCV) infection. We analyzed the association between CXCL9-11 polymorphisms and significant liver fibrosis in human immunodeficiency virus (HIV)/HCV-coinfected patients. METHODS We performed a cross-sectional study in 220 patients who were genotyped(More)
BACKGROUND The Fat Mass and Obesity-Associated Protein (FTO) gene rs9939609 single nucleotide polymorphism (SNP) has been associated with obesity, metabolic syndrome, insulin resistance (IR), and type 2 diabetes mellitus in the general population. The aim of our study was to examine for the first time the association of the rs9939609 polymorphism with(More)
