Durability of the first combined antiretroviral regimen in patients with AIDS at a reference center in Belo Horizonte, Brazil, from 1996 to 2005
Finding a better first antiretroviral regimen is one of the strategies used to improve span and quality of life of HIV/AIDS patients. 891 patients were followed during 24 months or until interruption/abandonment of treatment, changing regimen or death. At the end of 6 months, 69% of the patients wer...
