Ten million more people advised to take HIV drugs: UN

AFP, GENEVA, Switzerland

Nearly 10 million more people infected with the AIDS virus now meet medical standards for receiving HIV drugs, according to revised UN guidelines released yesterday, which experts say could avert 6.5 million deaths or new infections by 2025.

However, achieving this goal will be a challenge, as it will add about US$2 billion a year to the bill to fight the 32-year AIDS epidemic, they said.

“Treating people with HIV earlier ... can both keep them healthy and lowers the amount of virus in the blood, which reduces the risk of passing it to someone else,” the WHO said in new recommendations for combating the HIV/AIDS pandemic.

About 34 million people worldwide were living with HIV in 2011, nearly 70 percent of them in sub-Saharan Africa, according to WHO statistics.

The UN agency’s previous treatment guidelines, set down in 2010, called for drug initiation when the tally of CD4 cells — the key immune cells targeted by HIV — reached 350 cells or less per microliter of blood.

Under this benchmark, 16.7 million people in low and middle-income countries were medically eligible last year to receive the drug “cocktail,” which rolls back infection although it does not cure it.

Despite years of fundraising and efforts to build medical infrastructure in poor countries, only 9.7 million of the 16.7 million currently get the treatment.

WHO yesterday said that after weighing evidence for drug efficacy, benefits for the immune system and potential side effects, it recommended raising the CD4 threshold to 500 cells per microliter of blood.

That means treatment should start at a much earlier stage of infection. This, along with the recommendation to treat all infected pregnant women and children under five years — as well as other vulnerable groups, regardless of their cell-count — brings the number of patients who are advised to take these drugs to about 26 million, the WHO said.

“These guidelines represent another leap ahead in a trend of ever-higher goals and ever-greater achievements,” WHO chief Margaret Chan (陳馮富珍) said.

“With nearly 10 million people now on antiretroviral therapy, we see that such prospects — unthinkable just a few years ago — can now fuel the momentum needed to push the HIV epidemic into irreversible decline,” she added.

Michel Sidibe, who heads the UN’s AIDS prevention agency agreed, saying the new guidelines were “bringing us closer to what I would call the end of the AIDS epidemic.”

The aim is to get at least 15 million HIV patients onto antiretroviral therapy (ART) by 2015 and, by 2025, reach 80 percent coverage of those then in need.

However, both goals will require a major rise in funding.

“It’s not coming for free,” WHO HIV/AIDS department head Gottfried Hirnschall said.

Gradually adhering to the new guidelines will add 10 percent to the currently estimated between US$22 and US$24 billion needed each year to fully respond to the global HIV/AIDS epidemic. That figure includes not only treatment, but also prevention and diagnostics, he said.

In 2011, the actual global spending stood close to US$17 billion.

“But the impact will be substantial,” he said, adding that “we are expecting 3 million additional deaths avoided between now and 2025, and 3.5 million additional new infections averted.”

Sidibe said he believed that rather than growing, the costs of treating HIV patients would soon begin shrinking as drug and diagnostics prices continue their decline — and as countries find smarter ways of delivering the treatment.
