Cohort profile: the Ontario HIV Treatment Network Cohort Study (OCS).

The Ontario HIV Treatment Network Cohort Study (OCS) is an observational, open dynamic cohort of people who are receiving medical care for human immunodeficiency virus (HIV) infection in Ontario, Canada. Established in the mid-1990s, the OCS has its roots in AIDS activists' demands for research that would improve the quality of life of people living with HIV while respecting their privacy. It is a collaborative and community-driven study, including a Governance Committee made up of people with HIV and other stakeholders that evaluates analysis project proposals for community relevance and ethics.

Effect of baseline characteristics on the efficacy and safety of once-daily darunavir/ ritonavir in HIV-1-infected, treatment-naïve ARTEMIS patients at week 96.

Objectives: ARTEMIS demonstrated significantly greater efficacy of once-daily darunavir/ritonavir (DRV/r) 800/100 mg versus lopinavir/ritonavir 800/200 mg (total daily dose) in treatment-naïve, HIV-1-infected patients at week 96. The influence of baseline characteristics on efficacy and safety was analyzed in DRV/r patients.

Methods: Patients received once-daily DRV/r plus fixed-dose tenofovir/emtricitabine.
