An international group of scientists on Sunday called for all adults who test positive for HIV to be treated with antiretroviral drugs right away rather than waiting for their immune systems to weaken. http://medicalxpress.com/news/2012-07-international-group-urges-prompt-hiv.html HIV & AIDS Sun, 22 Jul 2012 15:19:13 EST news262189121 The percentage of HIV patients taking antiretroviral drugs who experienced the full benefit of the drugs jumped from 45 percent of 72 percent during the past decade, a figure that is lower than previous estimates. The findings, considered important for HIV prevention efforts, since patients whose virus is in tight control are less likely to transmit the infection to others, are published this week in JAMA by a team of researchers led by the Perelman School of Medicine at the University of Pennsylvania and Johns Hopkins University School of Medicine. The issue's publication coincides with AIDS 2012, the annual international AIDS conference, being held in the United States for the first in over 20 years this week in Washington, D.C. http://medicalxpress.com/news/2012-07-benefits-hiv-drugs-previously.html HIV & AIDS Sun, 22 Jul 2012 15:12:22 EST news262188661 Faced with the highest HIV-AIDS rates in the United States, community health activists in the nation's capital have come up with a novel way for people to save their own lives while killing time. http://medicalxpress.com/news/2012-07-washington-free-hiv-aids.html HIV & AIDS Fri, 20 Jul 2012 13:04:05 EST news262008238 The Nobel laureate who helped to discover HIV says there is hope for an AIDS cure following recent discoveries, in an interview with AFP ahead of a global conference on the disease. http://medicalxpress.com/news/2012-07-nobel-laureate-discoverer-hiv-sight.html HIV & AIDS Fri, 20 Jul 2012 05:10:01 EST news261979050 A new study by scientists on the Florida campus of The Scripps Research Institute shows, in cell culture, a natural compound can virtually eliminate human immunodeficiency virus (HIV) in infected cells.

In an update of a systematic review first published in 2009, the researchers found that uninfected people in relationships with HIV-infected partners, men who have sex with men and those in other high risk groups are at a lower risk of becoming infected with the virus if they regularly take drugs that are normally prescribed to treat people with HIV. http://medicalxpress.com/news/2012-07-drugs-hiv-infection.html HIV & AIDS Tue, 10 Jul 2012 19:00:02 EST news261160988 Scientists on Sunday said they had found a key piece in the puzzle as to why a tiny minority of individuals infected with HIV have a natural ability to fight off the deadly AIDS virus. http://medicalxpress.com/news/2012-06-revealed-secret-hiv-natural-born.html HIV & AIDS Sun, 10 Jun 2012 13:56:41 EST news258555394 In early results of a large-scale randomized study published in 2010 and led by researchers from the University of North Carolina at Chapel Hill, giving daily antiretroviral drugs (ART) to HIV-infected moms or their breastfeeding babies for 28 weeks proved safe and effective for preventing mother-to-child HIV transmission through breast milk. http://medicalxpress.com/news/2012-04-longer-breastfeeding-antiretroviral-drugs-hiv.html HIV & AIDS Wed, 25 Apr 2012 18:30:03 EST news254592611 A study in this week's PLoS Medicine suggests that when people are first infected with HIV (primary HIV infection), temporary treatment with antiretroviral drugs (cART) for 24 weeks can delay the need to restart treatment during chronic HIV infection. These findings are important as currently, treatment for people with HIV is often deferred until the CD4 count falls below a certain level (350) or is based on clinical symptoms. http://medicalxpress.com/news/2012-03-early-temporary-treatment-hiv-long-term.html HIV & AIDS Tue, 27 Mar 2012 17:00:10 EST news252083401 International funding cuts threaten to deepen an HIV crisis in Myanmar, where tens of thousands of people are denied lifesaving treatment, an aid agency said Wednesday. http://medicalxpress.com/news/2012-02-two-thirds-myanmar-hiv-patients-untreated.html HIV & AIDS Wed, 22 Feb 2012 05:28:12 EST news249110867 (AP) -- Business and social media leaders teamed up Friday to tackle the transmission of HIV from mothers to babies, saying the medicine and the money are largely in place, and with the right organizational skills they can eliminate HIV-infected births by 2015. http://medicalxpress.com/news/2012-01-business-social-media-babies-hiv.html HIV & AIDS Fri, 27 Jan 2012 06:40:01 EST news246867458 (Medical Xpress) -- For children and adolescents with HIV infection, the recent Food and Drug Administration (FDA) approval of the use of raltegravir, an antiretroviral drug that slows the spread of HIV infection, offers a new weapon to treat HIV infection in children.
