High effectiveness of efavirenz-based highly active antiretroviral therapy in HIV-1-infected patients with fewer than 100 CD4 cells/μl and opportunistic diseases: the EfaVIP Study (Efavirenz in Very Immunosuppressed Patients)

Abstract
We evaluated the therapeutic outcomes of all antiretroviral-naive HIV-1-infected patients with fewer than 100 CD4 cells/microl, who received efavirenz-based highly active antiretroviral therapy (HAART). Sixty-one percent suffered AIDS-defining diseases, and after a median follow-up of 45 weeks there were three deaths and five AIDS-related conditions (two relapses, three new). Efavirenz-based HAART was found to be effective in profoundly immunosuppressed HIV-1-infected patients.
