Factors associated with liver fibrosis in intravenous drug users coinfected with HIV and HCV.

Background: Reliable non-invasive methods for the evaluation of liver fibrosis are desirable, and the risk factors associated with fibrosis are not fully identified.

Methods: A cross-sectional study of a cohort of 805 HIV-HCV-coinfected patients with active HCV replication, most (95.2%) of whom were intravenous drug users, was conducted.

Characteristics and outcome of HIV infection in gypsies in the Spanish VACH Cohort.

Objective: To study the characteristics of HIV infection in the gypsy (Roma) population in Spain, as compared with those of the Caucasian, non-gypsy majority.

Design: Cross-sectional, historical cohort study from the Spanish VACH Cohort.

Methods: Patients attending VACH clinics between 1 June 2004 and 30 November 2004 were classified according to their racial and ethnic origin as "gypsies", Caucasian non-gypsy Spanish natives (CNGN), and "other" (the last being excluded from this study).

Effectiveness and safety of didanosine, lamivudine and efavirenz versus zidovudine, lamivudine and efavirenz for the initial treatment of HIV-infected patients from the Spanish VACH cohort.

Background: Preliminary data suggest that a once-daily combination of lamivudine, didanosine and efavirenz is an effective alternative regimen for antiretroviral-naive HIV-1-infected patients. However, data from randomized trials comparing this combination versus standard first-line regimens are not available yet. In an observational study, we analyse the efficacy and tolerability of didanosine plus lamivudine and efavirenz versus zidovudine plus lamivudine and efavirenz in a cohort of therapy naive patients.
