[Antiretroviral treatment for HIV infection. Where we are and where we are going?]

Antiretroviral treatment for HIV infection has evolved importantly during the last few years. Eradication of HIV is currently not a realistic target of antiretroviral therapy; however, long term virologic control is possible with current antiviral combinations in the majority of patients. This has resulted in a dramatic reduction in complications and mortality associated with AIDS, even though significant challenges remain. Some of them are the limited access to antiretroviral drugs that exist in most of the affected countries because of the elevated costs of the drugs, the high level of adherence needed for efficacy and the short term and long term toxicity. It is important that antiretroviral access programs financed with public funds consider the following points in their design: specialized prescription that optimizes the use of these resources, integration of prevention to care, evaluation of costs in a global perspective, and integration of research with medical care.
