BACKGROUND: miR-122 is an important host factor for hepatitis C virus (HCV) replication. The aim of this study was to assess the safety and tolerability, pharmacokinetics, and antiviral effect of a single dose of RG-101, a hepatocyte targeted N-acetylgalactosamine conjugated oligonucleotide that antagonises miR-122, in patients with chronic HCV infection with various genotypes. METHODS: In this randomised, double-blind, placebo-controlled, multicentre, phase 1B study, patients were randomly assigned to RG-101 or placebo (7:1)...

OBJECTIVES: HIV/hepatitis C virus (HCV) coinfection is associated with insulin resistance, but the mechanism is unclear. We hypothesized that intestinal epithelial damage and the consequent monocyte/macrophage activation and inflammation explain this perturbation. DESIGN: Cross-sectional study of 519 adults (220 HIV+/HCV-; 64 HIV-/HCV+; 89 HIV+/HCV+; 146 HIV-/HCV-). METHODS: We used multivariable linear regression to evaluate associations of HIV and HCV with the homeostasis model assessment of insulin resistance (HOMA-IR) and if intestinal fatty (FA) acid binding protein (I-FABP, a marker of gut epithelial integrity), soluble CD14 (sCD14) and soluble CD163 (sCD163) (markers of monocyte/macrophage activation), and IL-6 (an inflammatory cytokine) mediated this association...

The aim of the study was to characterize HCV infection in Northwest Spain and assess the impact of the Spanish Strategic Plan to cure HCV infection. Overall, 387 patients were included (60.9% HIV/HCV coinfected and 28.2% cirrhotic). Of these, 72.9% of patients that were recognized as priority for HCV treatment according to the Spanish Strategic Plan (≥F2, transplant or extrahepatic manifestations), initiated treatment during 2015. Globally, SVR12 was achieved in 96.5% of patients. The implementation of the Spanish Strategic Plan has been critical to advance in HCV cure, but 27...

BACKGROUND: Second-generation direct-acting antiviral agents are integral to treatment of hepatitis C (HCV) infection. Eight-week courses of ledipasvir/sofosbuvir (LDV/SOF) have been supported in some studies, but data are limited on efficacy in real-world use. Controversy exists regarding applicability of clinical trials to real-world effectiveness. We report virologic responses of patients with HCV genotype 1 infection receiving LDV/SOF for 8 or 12 weeks in a large integrated healthcare system...

: In contrast to other available next generation sequencing platforms, Pacbio Single Molecule, Real-Time (SMRT) sequencing has the advantage of generating long reads, albeit with a relatively higher error rate in unprocessed data. Using this platform we longitudinally sampled and sequenced the hepatitis C virus (HCV) envelope genome region (1680 nt) from individuals belonging to a cluster of sexually-transmitted cases. All five subjects were HIV-1 coinfected and infected with a closely related strain of HCV genotype 4d...

HIV and HCV share transmission routes including contaminated blood transfusion, sexual intercourse, and needle-sharing in injection drug users (IDUs). We obtained five near full-length genome sequences (NFLGs) of HCV isolated from five HIV-1 coinfected IDUs in Sichuan and Xinjiang province, China. By conducting reconstruction of neighbor-joining (NJ) phylogenetic tree, our results revealed that the five isolates are different genotypes (1b, 3a, 6a and 6n). The amino acid substitutions(170I) in XJN0021 related to resistant to protease inhibitors (Grazoprevir) were also identified...

The genetic analysis of THE natural protease inhibitors (PI) resistance of HCV genotype (GT)1 involves subtypes 1a and 1b. NS3 protease domain was sequentially analysed in 10 HIV/HCV GT1-coinfected individuals naïve to HCV treatment. Analysis at different time points showed that 2/3 GT1b patients were infected by a GT1a clade1 during follow-up. In one patient a switch from clade1 to clade2 and in one other patient a switch from clade2 to clade1 was revealed. Four out of ten patients had resistance-associated substitutions (RASs) at baseline...

Coinfection of hepatitis B virus (HBV) or hepatitis C virus (HCV) with HIV is common and associated with increased mortality and increased risk of progression to chronic liver disease. We aimed to study long-term liver diseases after initiation of antiretroviral therapy (ART) in HIV-infected patients with and without HBV or HCV coinfection. A retrospective cohort of 92 patients (32 patients with HBV and/or HCV coinfection) was analyzed. Overall mean age was 38.3 years, and 54.3% were males. Immunological and virological responses were similar between the 2 groups ( P > ...

The US Food and Drug Administration has now approved 10 direct-acting antivirals (DAAs) for the management of hepatitis C virus (HCV). These therapies are combined into 6 regimens that are given for varying durations, with or without ribavirin, depending on the viral genotype, the presence or absence of baseline resistance-associated variants (RAVs), and the patient type. RAVs may be present before exposure to a drug or may become detectable de novo during exposure to a drug. Emerging resistant strains are the most common cause of failure of HCV DAA regimens...

BACKGROUND: The viral RNA-dependent RNA polymerase (RdRp) enzymes of the Flaviviridae family are essential for viral replication and are logically important targets for development of antiviral therapeutic agents. Zika virus (ZIKV) is a rapidly re-emerging human pathogen for which no vaccine or antiviral agent is currently available. METHODS: To facilitate development of ZIKV RdRp inhibitors, we have established an RdRp assay using purified recombinant ZIKV NS5 polymerase...

The Scientific Registry of Transplant Recipients (SRTR) serves to collect data on organ transplants done in the United States. Although the infectious diseases data are limited and include mostly pretransplant serologies and other non-specific infection related outcomes, such multicenter data collection allows for insightful national data and the ability to monitor trends over time. We reviewed the published concise reports for each organ type in SRTR reports containing data from 2005-2014, and summarized our findings with respect to cytomegalovirus (CMV), Epstein-Barr virus, posttransplant lymphoproliferative disorder (PTLD), hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodefiency virus (HIV), general infection, and prophylaxis...

BACKGROUND: Immune thrombocytopenic purpura (ITP) is a hemorrhagic diathesis, characterized by platelets destruction alongside impaired production. Patients from Asian regions often exhibit distinctive characteristics in comparison to the western patients. We accomplished this study to evaluate the prevalence of primary versus secondary ITP along with the comparative analysis between them. The secondary objective was to determine the etiological spectrum of secondary ITP. METHODS: We illustrate the results of a large cohort of newly diagnosed adults ITP from southern Pakistan...

The genetic background of human populations can influence the susceptibility and outcome of infection diseases. Toll-like receptors (TLRs) have been previously associated with susceptibility to human immunodeficiency virus (HIV) infection, disease progression and hepatitis C, virus (HCV) co-infection in different populations, although mostly in Europeans. In this study, we investigated the genetic role of endosomal TLRs on susceptibility to HIV infection and HCV co-infection through the analysis of TLR7 rs179008, TLR8 rs3764880, TLR9 rs5743836 and TLR9 rs352140 polymorphisms in 789 Brazilian individuals (374 HIV+ and 415 HIV-), taking into account their ethnic background...
