Protease inhibitors (PIs) to treat hepatitis C (HCV) virus infection have been approved and others are under development. The aims of this study were to illustrate natural polymorphisms in the HCV protease and measure the frequency of PI resistance mutations in different HCV genotypes from PI-naïve patients. Direct sequencing of HCV NS3/4A protease was(More)
BACKGROUND Human immunodeficiency virus (HIV) infection is increasingly recognized as an important cause of dilated cardiomyopathy. However, the pathogenesis of the heart-muscle disease in the acquired immunodeficiency syndrome is unclear. METHODS We performed a prospective, long-term clinical and echocardiographic follow-up study of 952 asymptomatic(More)
Direct-acting antiviral (DAA) agents target HCV proteins; some of these have already been approved for the treatment of HCV infection, while others are in development. However, selection of DAA-resistant viral variants may hamper treatment. The aim of this study was to illustrate potential natural DAA-resistance mutations in the HCV NS5A and NS5B regions of(More)
BACKGROUND/AIMS Increased serum ferritin is thought to be responsible for activation of glutathione turnover in patients with chronic hepatitis C. The aim of the study was to evaluate a possible correlation between levels of serum ferritin and concentrations of hepatic, plasmatic and lymphocytic glutathione in a selected cohort of chronic hepatitis C(More)
The heart is frequently involved in the acquired immunodeficiency syndrome (AIDS). This study was planned to assess the prevalence of cardiac involvement in a large and selected population of patients who died of AIDS. Of 440 AIDS patients who underwent autopsy, cardiac involvement was documented in 82 patients. Dilated cardiomyopathy was found in 12(More)
OBJECTIVE The purpose of this article is to evaluate the diagnostic performance of transient elastography, real-time strain elastography, and aspartate-to-platelet ratio index in assessing fibrosis in patients with chronic hepatitis C by using histologic Metavir scores as reference standard. SUBJECTS AND METHODS Consecutive patients with chronic hepatitis(More)
BACKGROUND In patients with chronic hepatitis C virus (HCV) genotype 2 or 3, 24 weeks' treatment with pegylated interferon alfa (PEG-IFN-alpha) and ribavirin induces a sustained virological response (SVR) in almost 80% of cases. Evidence suggests that a similar response rate may be obtained with shorter treatment periods, especially in patients with a rapid(More)
BACKGROUND High cardiovascular risk and accelerated atherosclerosis are associated with human immunodeficiency virus (HIV). Recently, the use of highly active antiretroviral therapy (HAART) for the treatment of HIV infection is correlated with the development of HAART-associated metabolic syndrome and lipodystrophy (LDS). Detection of epicardial fat(More)
BACKGROUND The association of highly active antiretroviral therapy (HAART) regimens that include protease inhibitors (PIs) with metabolic and somatic disorders has raised concerns about the possibility of an increased risk of coronary artery disease (CAD) in patients with HIV infection. OBJECTIVE The aim of this study was to assess the incidence of CAD in(More)
AIM To evaluate if indolent B cell-non Hodgkin's lymphoma (B-NHL) and diffuse large B-cell lymphoma (DLBCL) in hepatitis C virus (HCV) positive patients could have different biological and clinical characteristics requiring different management strategies. METHODS A group of 24 HCV related B-NHL patients (11 indolent, 13 DLBCL) in whom the biological and(More)
