BARCELONA, Spain (Reuters Health) Jul 10 - In response to the growing problem of antiretroviral resistance, a Global HIV Drug Resistance Surveillance Network has been created, in part, to "facilitate antiretroviral 'gear-up' in the South," Dr. Scott Hammer of Columbia University in New York told participants at the XIV International AIDS Conference here on Wednesday.

Although there is much concern about the spread of HIV drug resistance, "it is not a reason to delay the introduction of antiretroviral therapy" in developing countries, he said. "We need to take the lessons we have learned about drug resistance in the developed world to the developing world." The data that we have on HIV drug resistance is "scattered," he continued. The network will provide a central source of this information.

The new global network on HIV drug resistance is a collaborative effort supported by the International AIDS Society, the World Health Organization, and other partners. The new program will be entirely Internet-based.

The WHO's current goal is to have 3 million HIV-infected patients on antiretroviral therapy by 2005. For the most part, there is currently very little HIV drug resistance in the South, Dr. Hammer said. One of the goals of the new surveillance network is to keep it that way after antiretrovirals are introduced in developing countries.

Another important reason to monitor drug resistance is the possibility that "there may be different susceptibilities of different HIV subtypes," Dr. Hammer continued.

"We're essentially talking about 'molecular epidemiology'," he elaborated. This new surveillance program will provide "data on the circulation, intermingling and recombinant forms of various HIV subtypes."
