Health Study: HIV Becoming Less Deadly


Study: HIV Becoming Less Deadly

HIV is evolving into a less infectious and deadly form, according to a study by the University of Oxford. When HIV infects an individual with an immune system better equipped to battle the virus, it may become less effective at replicating. This weaker version of the virus may then be passed on. The findings, published in the Proceedings of the National Academy of Sciences, demonstrate evidence of this process occurring in Africa by comparing versions of the virus in Botswana and South Africa. Researchers warn that even less infectious forms of HIV could still cause AIDS. More… Discuss

Americans with HIV Undertreated


Americans with HIV Undertreated

Only 30 percent of Americans infected with HIV have the virus under control, according to a new report by the US Centers for Disease Control and Prevention (CDC). Based on statistics from 2011, the report found that the remaining 70 percent failed to achieve “viral suppression” for a number of reasons. Of those individuals, 66 percent were not getting regular care; 20 percent were unaware they were infected; 10 percent were unable to suppress the virus with antiretroviral treatment; and 4 percent were not prescribed antiretroviral drugs. According to the CDC, up to 50,000 people in the US are infected with HIV every year. More… Discuss

HIV Reemerges in “Cured” Child


HIV Reemerges in “Cured” Child

A US-born toddler who, it had been hoped, had been cured of HIV after receiving antiretroviral treatment within hours of birth is, sadly, still infected. Tests had found no detectable levels of the virus in her blood as recently as March, despite the fact that she had not received treatment for nearly two years. Earlier this month, however, the four-year-old had a positive result. The news of the failed cure comes as a blow to the research community and indeed society at large. More… Discuss

ARTICLE: EARLY ANTIRETROVIRAL INTERVENTION HAS SECOND SUCCESS


Early Antiretroviral Intervention Has Second Success

A second baby may have been cured of HIV as a result of early, intensive antiretroviral drug therapy. One year ago, doctors reported the case of a baby who was believed to have been cured of HIV following aggressive antiretroviral therapy begun when she was just a day old. Now, doctors are reporting similar success with a second child. She was administered her first antiretroviral drugs just four hours after birth and, though she remains on a cocktail of these drugs to this day, doctors are optimistic that the lack of detectable HIV in her blood indicates that her infection is at the very least in remission if not cured. More… Discuss

AIDS CURE HOPES DASHED


AIDS Cure Hopes Dashed

Two American men who, it had been hoped, had been cured of HIV with a b one marrow transplant are unfortunately still infected with the virus. Following their respective transplants, which were performed to treat a type of blood cancer known as Hodgkin’s lymphoma, HIV dropped to undetectable levels in their blood. After several years, the men discontinued their antiretroviral therapy, and for months they continued to appear HIV-free. However, 12 weeks after the first patient stopped therapy and 32 weeks after the second patient did the same, signs of HIV returned. More… Discuss

 

TWO MORE MEN HIV-FREE AFTER BONE MARROW TRANSPLANTS


Two More Men HIV-Free after Bone Marrow Transplants

Doctors are reporting two more cases of HIV-positivepatients who underwent bone marrow transplants and now, years later, still have no detectable signs of the virus in their blood. While they are reluctant to label the patients cured at this early stage—one of the men has been off his anti-retroviral drug regimen for 15 weeks and the other just seven—the results thus far are encouraging. The men will continue to be closely monitored for any signs that the infection is rebounding. More…Discuss

Gamers Help AIDS Researchers Solve Enzyme Puzzle


Gamers Help AIDS Researchers Solve Enzyme Puzzle

In just weeks, online gamers were able to solve a puzzle that has stumped AIDS researchers for years. They did so using a game called Foldit, which allows players to compete against one another to, among other things, predict a protein‘s optimal—or most stable—three-dimensional structure. In this case, players were presented with M-PMV retroviral protease, an enzyme that is critical to the development of a virus similar to HIV. The protein model that the gamers came up with could help scientists develop better AIDS drugs. More… Discuss
