Development of hepatotoxicity in HIV patients switching at least one protease inhibitor.

In order to evaluate the occurrence of hepatotoxicity in patients treated with antiretroviral therapy (ART) who switch protease inhibitor (PI), and the role of viral hepatitis in its development, we performed a retrospective study on 182 HIV patients treated with ART for 24 months. The presence of hepatitis viruses and alanine transaminase levels were evaluated. Hepatotoxicity developed in a low number of subjects without co-infection, but was significantly higher in co-infected patients (14/51 versus 62/131, P = 0.

Hepatotoxicity development during antiretroviral therapy containing protease inhibitors in patients with HIV: the role of hepatitis B and C virus infection.

To evaluate the occurrence of hepatotoxicity in patients during antiretroviral therapy (ART) that contains protease inhibitors and the role of hepatitis viruses in its development, we performed a retrospective study including 1325 HIV-infected patients treated with ART for at least 6 months. Presence or absence of hepatitis viruses, alanine aminotransferase (ALT), total bilirubin, CD4 cell count, and plasma HIV RNA levels were evaluated. Hepatotoxicity developed in a few study subjects without coinfection, whereas it was significantly higher in coinfected patients.

Methodological issues in papers on IFN therapy: time for reappraisal.

We conducted an analytical review of 194 full papers on interferon (IFN) therapy for chronic hepatitis C to evaluate current methodology (i.e. study design, criteria for evaluating the efficacy of therapy and predictors of response).

Surgical procedures as a major risk factor for chronic hepatitis C virus infection in Italy: evidence from a case-control study.

Objectives: The study was carried out to evaluate the risk factors associated with chronic hepatitis C virus (HCV) infection.

Methods: This case-control study used multiple logistic regression analysis to determine risk factors associated with HCV infection. Study participants were followed at 10 liver or gastroenterologic units and included 294 subjects with chronic HCV infection and 295 age and sex matched anti-HCV-negative controls.

Hepatitis C virus infection of salivary gland epithelial cells. Lack of evidence.

Background: Hepatitis C virus genome (HCV-RNA) has been detected in whole salivary gland tissue of chronically infected patients. However, contamination of the tissue by plasma or blood cells was not excluded by the previous reports.

Aims: To assess whether HCV infects the salivary gland epithelial cells in patients with chronic HCV liver disease.
