History of Changes


A study concerning viral kinetic with 10 co-infected HIV-HCV patients on treatment with peginterferon alfa-2a + ribavirin o IFN + ribavirin was reported in Conference on Retroviruses and Opportunistic Infections 2002 by Dr. Torriani shown half-life of HCV virions and the viral clearance was larger than mono-infected patients.

The doubt is if this difference in viral kinetic of HIV-HCV co-infected patients versus mono-infected is related with the loss of profited on treatment.

In the APRICOT trial patients genotype 2/3 were treated for 48 weeks and the relapse rates was only 2%.

The present study want to evaluate is the treatment extent for 24 weeks more in patients genotype 1 and/or 4 will be improve the percentage of patients with viral clearance at the end of the follow-up period, to prevent relapsed in patients with response at the end of treatment.

Patients will be randomized to received 180 µg/week of peginterferon alfa-2a + 1000-1200 mg/day of ribavirin during 24 weeks more or control.
