We studied 648 hepatitis B surface antigen (HBsAg)- and/or anti-hepatitis C virus (HCV)-positive patients to evaluate the virologic and clinical characteristics of multiple hepatitis viral infection. We defined as Case B-C an HBsAg/anti-HCV positive patient and as Case b-C an anti-HCV/anti-HBc-positive, HBsAg/anti-HBs-negative patient. For each Case B-C we(More)
We enrolled 44 patients with hepatitis B virus (HBV) acute infection, 21 anti-hepatitis C virus (HCV)-positive for at least 1 year (case BC group), 20 anti-HCV-negative (control B group), and 3 with HBV/HCV acute concurrent infection. For each case BC, a subject with chronic HCV infection alone was selected (control C group). At the first observation, 85.7%(More)
OBJECTIVE To study the impact of occult hepatitis B virus (HBV) infection in 115 consecutive anti-HIV-positive, hepatitis B surface antigen-negative patients, naive for antiretroviral treatment. METHODS Of these 115, 86 patients were followed for at least 6 months (range 6-36) with serial determinations of HIV RNA and HBV DNA by polymerase chain reaction(More)
The plasma kinetics of a preparation of dilinoleoyl phosphatidylcholine (DLPC) specifically labeled with3H in the choline moiety and with14C in the 2-fatty acid (FA) were evaluated in six healthy volunteers after oral administration. Retention of both isotopes in plasma exceeded expectations, with a half-life in the elimination phase of 172.2 h for3H and(More)
Background:XIAP (X-linked inhibitor of apoptosis protein) is an anti-apoptotic protein exerting its activity by binding and suppressing caspases. As XIAP is overexpressed in several tumours, in which it apparently contributes to chemoresistance, and because its activity in vivo is antagonised by second mitochondria-derived activator of caspase (SMAC)/direct(More)
To evaluate whether HCV genotype and a "silent" HBV infection may be related to a more severe clinical presentation of liver disease, 205 anti-HCV/HCV-RNA positive, HBsAg/anti-HBs negative patients with chronic hepatitis (113 males and 92 females; median age 55 years, range 18-77), were studied on presentation at the Liver Unit from January 1993 to December(More)
Novel proapoptotic Smac mimics/IAPs inhibitors have been designed, synthesized and characterized. Computational models and structural studies (crystallography, NMR) have elucidated the SAR of this class of inhibitors, and have permitted further optimization of their properties. In vitro characterization (XIAP BIR3 and linker-BIR2-BIR3 binding, cytotox(More)
BACKGROUND Few data are available on histological features of chronic hepatitis B (HBV) and C (HCV) virus coinfection. PATIENTS AND METHODS We enrolled 142 consecutive patients with viral chronic hepatitis on their first liver biopsy: 27 HBsAg and anti-HCV positive (case BC group), 57 HBsAg positive and anti-HCV negative (control B group) and 58 anti-HCV(More)
Knowledge of the current epidemiology of chronic liver disease in Italy is mostly obsolete and fragmentary for the lack of up-to-date consistent data. In 2001, a 6-month prevalence study was undertaken in 79 hospitals to assess the characteristics of chronic liver disease in Italy. Both prevalent and incident cases were enrolled. A total of 9,997 patients(More)
Several 7-acyl cheno- and ursodeoxycholic acids were obtained in good yields starting from the corresponding cheno- and ursodeoxycholic acids, by a diacylation-selective hydrolysis procedure. A superior method for the synthesis of the 7-oleyl derivatives, by a selective acylation procedure, is also presented.
