We performed a genome-wide association study comparing a cohort of 144 human immunodeficiency virus (HIV type 1-infected, untreated white long-term nonprogressors (LTNPs) with a cohort of 605 HIV-1-infected white seroconverters. Forty-seven single-nucleotide polymorphisms (SNPs), located from class I to class III major histocompatibility complex (MHC)(More)
There is controversy about clinical management of patients who persistently have antibodies to hepatitis C virus (anti-HCV) but who have no symptoms and signs of liver disease. We have taken liver biopsy samples from 23 such patients (16 of whom had normal alanine aminotransferase [ALT] values) to assess prevalence of liver disease and to see whether(More)
OBJECTIVE To investigate the reciprocal inhibitory effects of hepatitis B virus (HBV)/hepatitis C virus (HCV)/hepatitis D virus (HDV) infections in naive and previously antiretroviral-experienced HIV-positive patients. DESIGN This retrospective study involved 72 consecutive patients of the Italian Cohort Naive Antiretroviral cohort: 21 coinfected with(More)
The clinical correlation between the degree of HCV variability and the response to anti-HCV treatment in HIV positive patients infected with HCV genotype 3a is unknown. In this study, 27 HIV positive and 5 HIV negative patients with HCV genotype 3a infection were treated with interferon-alpha-2b with or without ribavirin. Nine patients (5 HIV positive)(More)
BACKGROUND Chronic hepatitis C virus (HCV) infection has occasionally been associated with diseases of the central nervous system, thus suggesting that the virus has a direct effect on cerebral function. OBJECTIVE To investigate the presence and heterogeneity of HCV populations in the cerebrospinal fluid (CSF), plasma and peripheral blood mononuclear(More)
Chronic hepatitis B is usually a benign disease in Caucasian children; however, the long-term prognosis remains unsettled. This report describes the results of a 29-year longitudinal study including 99 white children with chronic hepatitis B, mainly acquired horizontally: 91 were hepatitis B e antigen (HBeAg) positive (4 had cirrhosis), and 8 were HBeAg(More)
The extent of mixed hepatitis C virus (HCV) genotype in different compartments (plasma and peripheral blood mononuclear cell, PBMC) and possible association with treatment efficacy in HIV/HCV coinfected patients remains to be unknown.The objective of this study was to elucidate the frequency of mixed genotype infection (MG), its profile in different(More)
The amino terminal region of the non structural gene 3 (NS3) of hepatitis C virus (HCV) is a chymotripsinlike serine-protease responsible for cleavage of the non structural proteins of Hepatitis C virus (HCV). In order to investigate the genetic variation of this region, we developed a nested PCR to obtain NS3 protease sequences from 54 patients chronically(More)
