To gain a clearer understanding of the rate progression to cirrhosis and its determinants in chronic hepatitis C virus (HCV) infection, systematic review published epidemiologic studies that incorporated assessment for has been undertaken. Inclusion criteria were more than 20 cases HCV information on either age subjects or duration infection. Of 145 examined, 57 fulfilled inclusion criteria. Least-squares linear regression was employed estimate rates cirrhosis, examine factors associated...

Substantial reductions in hepatitis C virus (HCV) prevalence among people who inject drugs (PWID) cannot be achieved by harm reduction interventions such as needle exchange and opiate substitution therapy (OST) alone. Current HCV treatment is arduous uptake low, but new highly effective tolerable interferon-free direct-acting antiviral (DAA) treatments could facilitate increased uptake. We projected the potential impact of DAA on PWID three settings. A dynamic transmission model was...

Objectives: To determine the protective efficacy of highly active antiretroviral therapy (HAART) against AIDS dementia complex (ADC) relative to other initial AIDS-defining illnesses (ADIs), Australian notification data over recent years were examined. Methods: All ADIs in Australia period 1992-1997 included. Three ADI groups established: ADC; predominantly central nervous system (CNS) (toxoplasmosis and cryptococcosis); non-CNS ADIs. For each grouping, proportion total ADIs, median CD4 cell...

Glecaprevir and pibrentasvir are direct-acting antiviral agents with pangenotypic activity a high barrier to resistance. We evaluated the efficacy safety of 8-week 12-week courses treatment 300 mg glecaprevir plus 120 in patients without cirrhosis who had hepatitis C virus (HCV) genotype 1 or 3 infection.We conducted two phase 3, randomized, open-label, multicenter trials. Patients infection were randomly assigned 1:1 ratio receive once-daily glecaprevir-pibrentasvir for either 8 12 weeks....

The aim of this study was to systematically evaluate state Medicaid policies for the treatment hepatitis C virus (HCV) infection with sofosbuvir in United States. reimbursement criteria were evaluated all 50 states and District Columbia. authors searched Web sites between 23 June 7 December 2014 extracted data duplicate. Any differences resolved by consensus. Data on whether covered coverage based following categories: liver disease stage, HIV co-infection, prescriber type, drug or alcohol...

Although 20%-40% of persons with acute hepatitis C virus (HCV) infection demonstrate spontaneous clearance, the time course and factors associated clearance remain poorly understood. We investigated to predictors among participants HCV using Cox proportional hazards analyses. Data for this analysis were drawn from an international collaboration nine prospective cohorts evaluating outcomes after infection. Among 632 HCV, 35% female, 82% Caucasian, 49% had interleukin-28 (IL28)B CC genotype...

Hepatitis C virus (HCV) infection is common in persons who inject drugs (PWID).To evaluate elbasvir-grazoprevir treating HCV PWID.Randomized, placebo-controlled, double-blind trial. (ClinicalTrials.gov: NCT02105688).Australia, Canada, France, Germany, Israel, the Netherlands, New Zealand, Norway, Spain, Taiwan, United Kingdom, and States.301 treatment-naive patients with chronic genotype 1, 4, or 6 were at least 80% adherent to visits for opioid agonist therapy (OAT).The immediate-treatment...

The phase IIb, double-blind, placebo-controlled PILLAR trial investigated the efficacy and safety of two different simeprevir (SMV) doses administered once-daily (QD) with pegylated interferon (Peg-IFN)-α-2a ribavirin (RBV) in treatment-naïve patients HCV genotype 1 infection. Patients were randomized to one five treatments: SMV (75 or 150 mg QD) for 12 24 weeks placebo, plus Peg-IFN RBV. arms stopped all treatment at week if response-guided therapy (RGT) criteria met; not meeting RGT...

Patients with hepatitis C virus (HCV) genotype 3 infection, especially those advanced liver disease, are a challenging population in urgent need of optimally effective therapies. The combination daclatasvir (DCV; pangenotypic nonstructural protein 5A inhibitor) and sofosbuvir (SOF; nucleotide 5B for 12 weeks previously showed high efficacy (96%) noncirrhotic infection. phase III ALLY-3+ study (N = 50) evaluated DCV-SOF ribavirin (RBV) treatment-naïve (n 13) or treatment-experienced 37)...
