Hoping to sharply cut HIV/AIDS transmission rates in the U.S., the Centers for Disease Control and Prevention (CDC) took the unusual step of recommending that doctors ask all patients from ages 13 to 64 whether they want to be tested for the virus. One in four Americans living with HIV don't know they are infected; for them, early diagnosis could mean early treatment and longer lives. Antiretroviral drug therapy has already saved nearly 3 million years of life in the U.S. alone. Meanwhile, the number of people living with HIV/AIDS around the world continues to grow, to 40 million...
...World Health Organization. Of these youngsters, perhaps 660,000 are sick enough to require medical intervention. Yet only 1 in 20 children who need ARVs get them. In addition, fewer than 1 in 10 HIV-positive mothers receive the drugs they need to keep from transmitting the virus to their newborns...
Alisha Saleem, 20, was born too early to benefit from the newest antiretroviral (ARV) drugs. In fact, there weren't any HIV treatments for adults, much less children, in 1986. Saleem, who contracted the virus from her mother, an intravenous-drug user, was 4 when she took her first AIDS drug, and even then the only option she had was AZT. Today doctors know that the best way to fight the virus is to hit it with three drugs at once, one of which is preferably a protease inhibitor. But early patients like Saleem had to learn the hard...
...According to the latest figures released by UNAIDS last week, 530,000 children under the age of 15 contracted HIV in the past year, most from their HIV-positive mothers who pass along the virus during birth. With their first breath, these children are born fighting for their lives. And while ever more life-saving antiretroviral (ARV) drugs are moving into places like Africa, thanks to the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) and the Global Fund, there just aren't enough doctors in these regions familiar with treating kids to use these drugs properly...
...that an HIV patient’s genetic charactersitics affect the rate at which the disease progresses. Associate Professor of Medicine Marcus Altfeld and his team found that the structure of inherited immune system molecules, known as HLA Class I, partially determines HIV patients’ reaction to the virus. “This means that some genetic factors have an important effect on HIV’s progression very early in infection,” Altfeld said. “What happens early in infection determines the rate at which the disease will progress as a whole...
