TyG index, HOMA score and viral load in patients with chronic hepatitis C due to genotype 1.

2011

Summary.  The triglycerides × glucose (TyG) index is a recently proposed surrogate marker of insulin resistance (IR), calculated from fasting plasma triglyceride and glucose concentrations. We tested the host and viral factors associated with Tyg and homeostasis model assessment (HOMA) scores, comparing their associations with histological features and with sustained virological response (SVR) in patients with genotype 1 chronic hepatitis C(G1CHC). Three hundred and forty consecutive patients with G1CHC were considered. All had a liver biopsy scored by one pathologist for staging and grading (Scheuer), and graded for steatosis, which was considered moderate–severe if ≥30%. Anthropometric an…

When and how to treat acute hepatitis C?

2003

Background: Appropriate treatment of acute hepatitis C is still a matter of controversy due to the lack of large controlled trials. Aim: To assess the effectiveness of interferon as treatment for acute hepatitis C by meta-analysis. Methods: MEDLINE search (1985-2002) was supplemented with manual searches of reference lists. Studies were included if they were controlled trials comparing interferon to no treatment and if they included patients with either post-transfusion or sporadic acute hepatitis C. Twelve trials were analyzed (414 patients). The outcome assessed was the sustained virological response (SVR) rate (undetectable hepatitis C virus RNA in serum at least 6 months after cessation…

Impact of body weight on virological and immunological responses to efavirenz-containing regimens in HIV-infected, treatment-naive adults

2015

Objective: The prevalence of overweight and obesity is increasing among HIV-infected patients. Whether standard antiretroviral drug dosage is adequate in heavy individuals remains unresolved. We assessed the virological and immunological responses to initial efavirenz (EFV)-containing regimens in heavy compared to normal-weight HIV-infected patients. Design: Observational European cohort collaboration study. Methods: Eligible patients were antiretroviral-naive with documented weight prior to EFV start and follow-up viral loads after treatment initiation. Cox regression analyses evaluated the association between weight and time to first undetectable viral load ( 50 copies/ml) after initial s…

Efficacy of 8 weeks elbasvir/grazoprevir regimen for naïve-genotype 1b, HCV infected patients with or without glucose abnormalities: Results of the E…

2022

Background and aim: Direct Acting Antivirals(DAAs) achieve the highest rate of sustained viral re- sponse(SVR) in patients with genotype-1b(G1b) Hepatitis C virus(HCV) infection. Reducing treatment du- ration can simplify the management and improve adherence of therapy. Patients and methods: The study evaluates the efficacy of 8 weeks of elbasvir/grazoprevir regimen in 75 treatment-naïve(TN), G1b patients with mild-moderate fibrosis(Liver Stiffness by Fibroscan®< 9.0 kPa). Viral load(VL) has been evaluated by Roche TaqMan RT-PCR(LLOQ < 15 IU/ml). Results: Mean age was 61.0 ±14.2 years, 44% were male, mean LS by Fibroscan®was 6.1 ±1.8 kPa. Twenty-eight patients(37.3%) had an HOMA > …

Adefovir for lamivudine resistant HBV: More than meets the eye

2007

– In patients with LAM resistance and high levels of HBV-DNA, especially if HBeAg positive, it may be difficult to obtain a strong virological suppression with ADV. – Restrictive criteria are needed to define virological response (HBV-DNA < 10 3 copies/ml or 200 IU/ml). – Early finding of non-response or of suboptimal response after 9–12 months of ADV therapy suggests a high risk of emergence of ADV-resistant strains and should prompt a change of treatment strategy. In patients with cirrhosis, due to the risk of liver failure, treatment changes should be considered even earlier, at 3–6 months.

Dual therapy with peg-interferon and ribavirin in thalassemia major patients with chronic HCV infection: Is there still an indication?

2016

Background: Iron overload and hepatitis C virus (HCV) infection together can lead to chronic liver damage in thalassemia major (TM) patients. Aims: We investigated viral, genetic, and disease factors influencing sustained virological response (SVR) after peg-interferon and ribavirin therapy in TM patients with HCV infection. Methods: We analyzed 230 TM patients with HCV infection (mean age 36.0 ± 6.3 years; 59.1% genotype 1; 32.2% genotype 2; 3.4% genotype 3; and 5.3% genotype 4; 28.7% carried CC allele of rs12979860 in IL28B locus; 79.6% had chronic hepatitis and 20.4% cirrhosis; 63.5% naive and 36.5% previously treated with interferon alone) treated in 14 Italian centers. Results: By mul…

Practice guidelines for the treatment of hepatitis C: recommendations from an AISF/SIMIT/SIMAST Expert Opinion Meeting.

2010

It is increasingly clear that a tailored therapeutic approach to patients with hepatitis C virus infection is needed. Success rates in difficult to treat and low-responsive hepatitis C virus patients are not completely satisfactory, and there is the need to optimise treatment duration and intensity in patients with the highest likelihood of response. In addition, the management of special patient categories originally excluded from phase III registration trials needs to be critically re-evaluated. This article reports the recommendations for the treatment of hepatitis C virus infection on an individual basis, drafted by experts of three scientific societies.

Treatment of Hepatitis C virus infection in Italy: A consensus report from an expert panel

2017

Abstract Hepatitis C virus (HCV) infection remains one of the main causes of chronic liver disease worldwide. The advent of direct-acting antivirals (DAAs) has significantly improved the course of patients with chronic HCV infection (CHC), due to the ability of these drugs to achieve high rates of sustained virological response (SVR). These exceedingly high rates of SVR and the excellent safety data have been confirmed in real life practice. Evolving guidelines have been issued by national and international scientific societies in accordance with the progression of clinical knowledge and the availability of new DAAs. These recommendations, however, may not be applied universally because of …
