The Latest in AIDS Research from UNC Chapel Hill
There’s good news and bad news for those who suffer from AIDS in the developing world.

On July 20, researchers, public health institutions, international policymakers and numerous others gathered in Vancouver, Canada for the eighth International AIDS Society Conference. Myron Cohen of the University of North Carolina Chapel Hill’s Institute for Global Health & Infectious Disease had an interesting announcement. This announcement was the result of a huge, cross-sectional study on AIDS called HPTN 052 that he conducted on over 1,700 couples worldwide.

It wasn’t the first time that a major breakthrough had come out of Vancouver. At the same conference in 1996, AIDS research showed that it was possible to effectively treat AIDS, when contracting the disease previously would almost always lead to an early death.

First, the good news. According to Cohen, a particularly potent cocktail of AIDS medications can effectively render the disease incommunicable, as long as medicines are taken consistently. In the study, the treatment was shown to cut the risk of infection by 96 percent. This type of preventative treatment is known as antiretroviral therapy. If patients stop taking these antiretroviral drugs, the infection will reemerge.

While the study was almost entirely confined to heterosexual couples, Cohen said that, “Observational studies show it should work in men who have sex with men and we’re doing a study now looking at intravenous drug users.”

This means that if the current generation of those who suffer from AIDS can adhere to a strict regimen, they can avoid passing on the disease to successive generations. If treatment is widespread enough, this could eventually eradicate the disease.

However, there is a downside. The combination of antiretroviral drugs that can cripple the disease is quite expensive, making them all but inaccessible to the poor.

This hasn’t stopped the World Health Organization (WHO) from enthusiastically recommending that anyone who tests positive for HIV be immediately given antiretroviral treatment. WHO had previously recommended antiretroviral therapy for certain demographics, such as pregnant women and children, but has since expanded their recommendation based on the results of the study. Gottfried Hirnschall, director of WHO’s HIV/AIDS division, has noted that reaching currently untreated populations around the world would require an extra $30 billion in funding.

Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, who funded Cohen’s study, has said that, “For a long time there was the tension between whether you should focus on preventing HIV infection or treating HIV infection, [but] HPTN 052 showed that treatment is prevention.” However, given that antiretroviral treatment is so expensive, prevention strategies such as the use of condoms should still probably remain a prominent feature of global health policies.

Fortunately, there is cause to be optimistic about the capacity of global institutions and aid contributors to address the AIDS epidemic. Michel Sidibe, executive director of the United Nations Program on HIV/AIDS, points out that the world has reached its target of treating 15 million of the 35 million people infected with the virus worldwide by 2015. Perhaps in another 15 years, the remaining 20 million people who suffer from AIDS will have access to treatment as well.

The Aga Khan Foundation’s Canadian division is celebrating after having raised $1.75 million on Sunday, May 26th. Thousands of people participated in the World Partnership Walk, which took place in Vancouver. The proceeds will be earmarked to fund poverty-reducing programs in Asia and Africa, including providing clean water and ensuring that children have access to education. One specific project provides in-factory daycare services for textile workers in Bangladesh.

Last year alone, 40,000 Canadians participated in similar walks in ten different cities. Since it was first organized in 1985, the walk has raised over $75 million. All of the money raised goes directly towards international development. Not a single cent is spent on administration.

The foundation is a subsidiary agency of the Aga Khan Development Network, which is a group of private, non-denominational organizations that operates in 30 countries around the world. Though the title of Aga Khan is a religious one, the organization’s agencies conduct their programs “without regard to faith, origin, or gender.” Other agencies within the network focus more on areas like education, health, and economic development.

Similar walks are being planned for later this year all across America by Aga Khan Foundation U.S.A.
