WHO advises earlier treatment among people with HIV

Vienna - An estimated 5.2 million people in low and middle-income countries were receiving life-saving HIV treatment at the end of 2009, according to the latest update from WHO.

WHO estimates that 1.2 million people started treatment in 2009, bringing the total number of people receiving treatment to 5.2 million, compared to 4 million at the end of 2008.

"This is the largest increase in people accessing treatment in a single year. It is an extremely encouraging development," says Dr Hiroki Nakatani, WHO Assistant Director-General for HIV/AIDS, Tuberculosis, Malaria and Neglected Tropical Diseases.

At the XVIII International AIDS Conference, WHO is calling for earlier treatment for people with HIV. The objective is to begin HIV treatment before they become ill because of weakened immunity.

"Starting treatment earlier gives us an opportunity to enable people living with HIV to stay healthier and live longer,” says Dr Gottfried Hirnschall, WHO Director of HIV/AIDS.

Estimates developed through epidemiological modeling suggest that HIV-related mortality can be reduced by 20% between 2010 and 2015 if these guidelines for early treatment are broadly implemented.

Earlier treatment can prevent opportunistic infections including tuberculosis (TB), the number one killer of people with HIV. Deaths from TB can be reduced by as much as 90%, if people with both HIV and TB start treatment earlier.

The strength of a person's immune system is measured by CD4 cells. A healthy person has a CD4 count of 1000 - 1500 cells/mm3. WHO previously recommended starting HIV treatment when a person's CD4 count drops below 200 cells/mm3 but now advises starting HIV treatment at 350 cells/mm3 or below.
