THE number of people receiving medicines for the AIDS virus leapt by a quarter last year but more patients need to be brought into treatment before they are too sick, the World Health Organization said yesterday.
Presenting the data at an international conference on AIDS in Vienna, Austria, the WHO said an estimated 5.2 million people were being treated for the AIDS virus at the end of 2009 after an extra 1.2 million people started treatment during the year.
It described the increase - the largest in a single year - "an extremely encouraging development" but called for more programs to help patients receive treatment before the virus starts to make them very sick.
"Starting treatment earlier gives us an opportunity to enable people living with HIV to stay healthier and live longer," said Gottfried Hirnschall, WHO director of HIV/AIDS.
An estimated 33.4 million people now live with HIV/AIDS around the world. The United Nations says 15 million people need AIDS drugs, so the latest increase means that only just over a third are getting them.
Earlier HIV treatment can prevent so-called "opportunistic infections," including tuberculosis, which is the biggest killer of people with HIV.
The costs for HIV treatment in 2010 will be about US$9 billion, according to the Joint United Nations Program on HIV/AIDS.
The WHO says deaths from TB could be cut by as much as 90 percent if people with both HIV and TB started treatment earlier, when their immune systems have not been weakened too much by the virus.
The strength of a person's immune system is measured by CD4 cells and this measure is used by doctors to assess when HIV-infected patients should start receiving medicines.
The WHO previously recommended starting HIV treatment when a person's CD4 count dropped below 200 cells/mm3 but it now advises starting treatment earlier, at 350 cells/mm3 or below.
In rich nations, HIV patients begin treatment before their CD4 count drops significantly.
As a result they are able to live longer and more normal lives despite having the incurable virus.
A lack of funds and of healthcare infrastructure in poorer nations, where the virus is more widespread, mean patients have to wait until they are very ill before they get access to drugs.
WHO estimates that HIV-related deaths could be reduced by 20 percent between 2010 and 2015 if the new treatment guidelines were broadly implemented.
