    AIDS Drugs Offer Hope of Normal Lifespan in Africa

    艾滋防治药物让非洲人有望达到正常寿命

    Over the last 30 years life expectancy rates in Africa plummeted, as HIV/AIDS claimed millions of lives. But a new study says antiretroviral

     drug treatment can dramatically reverse that trend.

    在过去的三十年里,艾滋病夺去了非洲上百万的生命,这也使得非洲的预期寿命

    急剧降低.而今,科学给了我们转机:一项新研究表明,抗逆转录药物的使用可大

    幅度的扭转这一趋势.

    Professor Jean Nachega co-authored the study of some 20,000 patients in Uganda. He said, “The overall key finding of our study is that the patient in Africa receiving antiretroviral therapy for HIV can expect to live a near normal lifespan.”

    The findings were released at the International AIDS Society Conference on HIV Pathogenesis, Treatment and Prevention in Rome and published

     in the Annals of Internal Medicine.

Lost years

Nachega is a professor of medicine at South Africa’s Stellenbosch

    University and a scientist at the Johns Hopkins Bloomberg School of Public Health, before the HIV/AIDS epidemic, expected lifespans in many African countries had risen sharply. Nachega witnessed the change caused by the disease, cutting 15, 20 or more years from life expectancy.

    "All whatwe’ve been able to gain in the past with the access to clean water, expanded immunization programs were totally reversed with the HIV/AIDS epidemic in Africa. So now we are seeing some good news that investing in antiretroviral programs, those investments are now paying off.”

    He credits PEPFAR, the President’s Emergency Plan for AIDS Relief, and the Global Fund to Fight AIDS, Tuberculosis and Malaria.

Gender differences

    However, while the overall findings are positive, they do show a difference between men and women. Women are living longer. One reason is that men wait longer before receiving treatment.

    seeking behavior as compared to "Men just in general have a less health-

    females. Men spend more time looking for a job and spending more time away from their family to try to find a way to survive, I think may be one of the reasons. The second reason is obviously the issue about stigma, which is still quite affecting the majority of the people in the community.”

    Women may have a greater opportunity to learn their HIV status and receive treatment through pre-natal care programs. He says health officials need to “think hard” about how to overcome the “gender imbalance” in treatment.

    Professor Nachega supports the strategy of using treatment as prevention.

    "We should no longer see treatment and prevention totally separately. Treatment, by itself, is also part of prevention. Because by treating people, and hopefully treating them earlier, they are less likely to transmit the virus to their sexual partner.”

    Studies also show that giving uninfected people antiretrovirals can help protect them from HIV during sex with their infected partners. It’s called preexposure prophylaxis (PrEP).

    Professor Nachega says with the prevention tools now available, great progress can be made against the epidemic. But he says the magic bullet of an effective AIDS vaccine remains elusive.
