Time course of insulin resistance during antiviral therapy in non-diabetic, non-cirrhotic patients with genotype 1 HCV infection

2009

Background Genotype 1 (G1) hepatitis C virus (HCV) is associated with insulin resistance (IR) and its clearance seems to improve insulin sensitivity. We aimed to evaluate the time course of IR in response to antiviral therapy in non-diabetic, non-cirrhotic G1 HCV patients and to assess the effect of metabolic factors on sustained virological response (SVR). Methods A total of 83 consecutive treatment-naive G1 chronic hepatitis C (CHC) patients were evaluated by anthropometric and metabolic measurements, including IR using the homeostasis model assessment (HOMA). Patients were considered to have IR if HOMA was >2.7. All cases had a liver biopsy scored for staging, grading and steatosis. A…

Early menopause is associated with lack of response to antiviral therapy in women with chronic hepatitis C.

2011

Background & Aims Chronic hepatitis C (CHC) and liver fibrosis progress more rapidly in men and menopausal women than in women of reproductive age. We investigated the associations among menopause, sustained virologic response (SVR), and liver damage in patients with CHC. Methods We performed a prospective study of 1000 consecutive, treatment-naive patients 18 years of age and older with compensated liver disease from CHC. Liver biopsy samples were analyzed (for fibrosis, inflammation, and steatosis) before patients received standard antiviral therapy. From women (n = 442), we collected data on the presence, type, and timing of menopause; associated hormone and metabolic features; serum lev…

Regression of fibrosis after HBV antiviral therapy. Is cirrhosis reversible?

2014

Long-lasting HBV-DNA suppression is considered to be the best surrogate end-point of antiviral therapy in patients with hepatitis B virus (HBV) related chronic hepatitis or cirrhosis, and it is a prerequisite to prevent liver-related complications and improve survival. Treatment with oral antiviral drugs in patients with HBV cirrhosis is effective in restoring liver function and improving survival even in those with decompensated cirrhosis. These agents are generally well-tolerated for long-term treatment, and several evidences have demonstrated that they are able to reverse liver fibrosis and prevent the occurrence of HCC.

Pulmonary cytomegalovirus (CMV) DNA shedding in allogeneic hematopoietic stem cell transplant recipients: Implications for the diagnosis of CMV pneum…

2019

Highlights • CMV DNA is frequently detected in BAL fluid specimens from allo-HSCT. • CMV DNA detection in BAL fluids is comparable across pneumonia etiologies. • CMV DNA loads in BAL fluids are comparable across pneumonia etiologies. • CMV DNA load in BAL may predict attributable-pneumonia mortality.

Multiclass HCV resistance to direct-acting antiviral failure in real-life patients advocates for tailored second-line therapies

2017

Background & Aims: Despite the excellent efficacy of direct-acting antivirals (DAA) reported in clinical trials, virological failures can occur, often associated with the development of resistance-associated substitutions (RASs). This study aimed to characterize the presence of clinically relevant RASs to all classes in real-life DAA failures. Methods: Of the 200 virological failures that were analyzed in 197 DAA-treated patients, 89 with pegylated-interferon+ribavirin (PegIFN+RBV) and 111 without (HCV-1a/1b/1g/2/3/4=58/83/1/6/24/25; 56.8% treatment experienced; 65.5% cirrhotic) were observed. Sanger sequencing of NS3/NS5A/NS5B was performed by home-made protocols, at failure (N= 200) and w…

Comments on "Real-world re-treatment outcomes of direct-acting antiviral therapy failure in patients with chronic hepatitis C".

2022

Dear Editor, Elhence et al.1 assessed the retreatment outcomes of direct‐ acting antivirals (DAAs) therapy failure in a cohort of 40 patients with chronic hepatitis C (HCV) and previous virological failure (VF) to DAAs. The results were remarkable, with an overall sustained virologic response (SVR) of 100% in patients who completed retreatment with sofosbuvir and velpatasvir (with/without ribavirin). We compared these results with our experience in the multicenter HCV‐ Surveillance Cohort Long‐Term Toxicity Antivirals (HCV‐SCOLTA) cohort, an active pharmacovigilance system supported by the CISAI group (Italian Coordinators for the Study of Allergies and HIV Infection). Since 2012, Italian i…

Characteristics of patients with hepatitis C virus-related chronic liver diseases just before the era of oral direct-acting antiviral therapy in Italy

2018

Background In 2017, oral direct-acting antiviral (DAA) therapy for chronic hepatitis C virus (HCV) infection became available free of charge for all HCV-RNA-positive patients, irrespective of their fibrosis stage. Aim The aim of this study was to evaluate the characteristics of HCV-related chronic liver disease (CLD) in Italy just before the introduction of DAA therapy. Patients and methods Patients with CLD were enrolled in two national surveys conducted in 2001 and in 2014. The two surveys prospectively enrolled patients aged older than 18 years referring to Italian liver units throughout the country using a similar clinical approach and analytical methods. Results Out of the 12 564 patie…

Who is more likely to respond to dual treatment with pegylated-interferon and ribavirin for chronic hepatitis C? A gender-oriented analysis.

2013

Summary We assessed, in real-life practice, viral, demographic, genetic and metabolic factors influencing the sustained virologic response (SVR), with a gender-oriented analysis, in patients with chronic hepatitis C virus (HCV) treated with pegylated interferon and ribavirin. Six hundred and seventy naive patients were treated with dual therapy and evaluated by gender and HCV genotype. Associations between baseline variables and SVR were assessed by multivariate logistic regression analysis. Among 362 genotype 1 patients, SVR was achieved in 158 patients (44%), and SVR was independently associated with age less than 50 years (OR 2.12; 95% CI 1.09–4.30; P = 0.039) and C/C genotype rs12979860…

Transmission of HIV Drug Resistance and the Predicted Effect on Current First-line Regimens in Europe

2016

Transmitted human immunodeficiency virus drug resistance in Europe is stable at around 8%. The impact of baseline mutation patterns on susceptibility to antiretroviral drugs should be addressed using clinical guidelines. The impact on baseline susceptibility is largest for nonnucleoside reverse transcriptase inhibitors.

Identification of Naïve Hcv-1 Patients with Chronic Hepatitis who may Benefit from Dual Therapy with Peg-Interferon and Ribavirin.

2014

Background & Aims The pool of HCV genotype 1 patients likely to be cured by peg-interferon and ribavirin remains to be quantified. Methods In 1045 patients treated with peg-interferon and ribavirin, two therapeutic strategies were confronted: the first one evaluated only baseline variables associated with sustained virological response (SVR), and the second one included the rapid virologic response (RVR) in addition to baseline predictors. An 80% SVR rate was the threshold to retain a strategy as clinically relevant. Results Overall, 414 patients (39.6%) attained SVR. In the first strategy, the hierarchy of features independently associated with SVR was IL28B CC genotype (OR 5.082; CI 3.637…
