Highly active antiretroviral therapy in resource-poor settings: the experience of Médecins Sans Frontières

We describe the short-term results of highly active antiretroviral therapy (HAART) in seven projects in low and middle income countries. A total of 743 adults were included, and clinical, immunological and virological responses were analysed. At 6 months, outcomes were similar to those observed in western countries, and the probability of remaining on treatment was 94%. The challenge now is to extend access to HAART to the millions in urgent need.
