Impact of early versus late adherence to highly active antiretroviral therapy on immuno-virological response: a 3-year follow-up study.

Objective: To assess the impact of different patterns of adherence to highly active antiretroviral therapy (HAART), in particular, the relative impact of early and late adherence, on long-term immuno-virological response in HIV-infected individuals started on a protease inhibitor-containing regimen.

Design: Clinical, immuno-virological and self-reported adherence data were collected at 4 (M4), 12 (M12), 20 (M20), 28 (M28) and 36 (M36) months after HAART initiation in the French APROCO cohort.

Methods: A standardized self-administered questionnaire classified patients as non-adherent, moderately or highly adherent at each visit.

Factors associated with mortality in human immunodeficiency virus type 1-infected adults initiating protease inhibitor-containing therapy: role of education level and of early transaminase level elevation (APROCO-ANRS EP11 study). The Antiprotéases Cohorte Agence Nationale de Recherches sur le SIDA EP 11 study.

This study attempted to identify factors associated with mortality among human immunodeficiency virus (HIV)-infected adults starting a protease inhibitor (PI)-containing therapy. Among 1155 patients consecutively enrolled in the APROCO study between May 1997 and June 1998, clinical characteristics were as follows: median age, 36 years; median baseline CD4 cell count, 288 cells/mm(3); and median baseline plasma HIV RNA load, 4.4 log(10) copies/mL.

Predictors of long-term increase in CD4(+) cell counts in human immunodeficiency virus-infected patients receiving a protease inhibitor-containing antiretroviral regimen.

The temporal relationships between plasma human immunodeficiency virus (HIV) RNA levels and evolution of CD4(+) cell counts was studied, using a 2-slope longitudinal mixed model, in 988 patients prospectively enrolled at the initiation of a protease inhibitor--containing regimen of antiretroviral therapy. The short-term slope (baseline through month 4) for mean change in CD4(+) cell count was +21.2 cells/mm(3)/month, and the long-term slope (month 4 through month 24) was +5.
