Advances in HIV treatment have led to a significant decline in AIDS related
morbidity and mortality. Guidelines have been developed to assist clinicia
ns in choosing combination therapy for individual patients and the monitori
ng of patients' progress through HIV RNA plasma levels and CD4 counts. Reco

now focus on simplifying medication schedules and understanding complicati
ons of therapy such as drug interactions and long-term side effects. Pivota
l trials, investigational agents, once-daily therapy, and directly observed
therapy are also discussed.
