World Health Organization issues new guidelines on HIV treatment

Everyone with HIV should be given antiretroviral drugs as soon as possible after diagnosis, meaning 37 million people worldwide should be on treatment, the World Health Organization says.

Move comes after early ART therapies hailed in multiple studies

Everyone with HIV should be given antiretroviral drugs as soon as possible after diagnosis, meaning 37 million people worldwide should be on treatment, the World Health Organization (WHO) said today.

Recent clinical trials have confirmed that early drug use extends the lives of those with the AIDS-causing virus and cuts the risk of disease transmission to partners, the WHO said in a statement setting out the new goal for its 194 member states.

Under previous WHO guidelines, which limited treatment to those whose immune cell counts had fallen below a certain threshold, 28 million people were deemed eligible for antiretroviral therapy (ART).

All people at "substantial" risk of contracting HIV should also be given preventive ART, not just men who have sex with men, the WHO said.

The new guidelines are a central plank of the United Nations agency's aim to end the AIDS epidemic by 2030.

"Everybody living with HIV has the right to life-saving treatment. The new guidelines are a very important step towards ensuring that all people living with HIV have immediate access to antiretroviral treatment," said Michel Sidibe, Executive Director of UNAIDS.

"According to UNAIDS estimates, expanding ART to all people living with HIV and expanding prevention choices can help avert 21 million AIDS-related deaths and 28 million new infections by 2030."

The move will lead to a sharp increase in demand for ART medicines, which are typically given as a three-drug cocktail to avoid the risk of the virus developing resistance.

Major suppliers of HIV drugs include Gilead, ViiV Healthcare, which is majority-owned by GlaxoSmithKline (GSK) , and multiple Indian generic manufacturers.

All people at "substantial" risk of contracting HIV should also be given preventive antiretroviral treatment, not just men who have sex with men, the WHO said.

The medical charity Medecins Sans Frontieres (Doctors Without Borders) welcomed the move to expand treatment but warned that "turning this new recommendation into reality would require dramatically increased support from donors and governments."

Treat-now approach pioneered in B.C.

MSF said its experience showed that a third of people who were diagnosed with HIV, but not eligible to start treatment, never returned to the clinic.

Canadian physicians have already been adopting the treat-now approach, afterclinical trials showed not only did early intervention with antiretrovirals extend the lives of patients, but the drugs also cut theirrisk of infecting others.

The strategy was pioneered by the BC Centre for Excellence in HIV/AIDS in Vancouver. Pressure is now on donor countries to help pay for it, said thecentre's Dr. Rolando Barrios.

"Our federal government has not been interested in supporting these initiatives," Barrios said. "But we hope that now that this is not an ideological discussion, now it's based on science, we hope that our politicians will take action."

Barrios admits efforts to treat HIVon a global scale have exceeded his expectations. He believes WHO's plan to eliminate AIDS by 2030 is achievable.

The WHO estimates that by 2020 low- and lower-middle income countries will need $18.4 billion US annually for the expanded HIV fight. However, fast-tracking the response should yield economic returns of $15 US per dollar invested, based on improved health and infections averted.

Since it began spreading 30 years ago, AIDS has killed around 40 million people worldwide.
