Results of a study published online in the Journal of Antimicrobial Chemotherapy today (Thursday), demonstrate that computer models can predict how HIV patients whose drug therapy is failing will respond to a new treatment. Crucially for patients in poorer countries, the models do not require the results of expensive drug resistance tests to make their predictions. The study also showed that the models were able to identify alternative drug combinations that were predicted to work in cases where the treatment used in the clinic had failed, suggesting that their use could avoid treatment failure. http://medicalxpress.com/news/2013-03-patients-hiv-drugs.html HIV & AIDS Wed, 13 Mar 2013 20:10:01 EST news282421952 (Medical Xpress)—Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV) while leaving surrounding cells unharmed, researchers at Washington University School of Medicine in St. Louis have shown. The finding is an important step toward developing a vaginal gel that may prevent the spread of HIV, the virus that causes AIDS. http://medicalxpress.com/news/2013-03-nanoparticles-bee-venom-hiv.html HIV & AIDS Fri, 08 Mar 2013 08:20:29 EST news281953153 What do cancer cells, weeds, and pathogens have in common? They all evolve resistance to the treatments that are supposed to eliminate them. However, researchers developing the next generation of antibiotics, herbicides, and anti-cancer therapeutics rarely come together to explore the common evolutionary principles at work across their different biological systems. http://medicalxpress.com/news/2013-03-american-academy-microbiology-resistance.html Other Thu, 07 Mar 2013 10:24:36 EST news281874267 US doctors have reported that, for the first time ever, a baby has been cured of HIV following drug treatment within hours of her birth. http://medicalxpress.com/news/2013-03-baby-hiv-expertsrespond.html HIV & AIDS Mon, 04 Mar 2013 07:53:37 EST news281606002 Researchers have moved a step closer to finding a cure for HIV by successfully luring the 'sleeping' virus out of hiding in infected cells. http://medicalxpress.com/news/2013-03-hiv.html HIV & AIDS Mon, 04 Mar 2013 07:50:01 EST news281604450 Researchers at the University of Pittsburgh School of Medicine may have found an "Achilles heel" in a key HIV protein.

One of the challenges researchers face involves fully eradicating the virus when it is latent in the body. A new report appearing in the December 2012 issue of the Journal of Leukocyte Biology suggests that a cancer drug, called JQ1, may be useful in purging latent HIV infection by activating the virus in the presence of potent therapy – essentially a dead end for the virus. http://medicalxpress.com/news/2012-11-cancer-drug-eradicating-latent-hiv.html HIV & AIDS Thu, 29 Nov 2012 11:32:17 EST news273411124 A combination of anti-HIV drugs has been found to also reduce the risk of recurrent malaria by nearly half among HIV-positive children, according to researchers supported by the National Institutes of Health. http://medicalxpress.com/news/2012-11-hiv-treatment-malaria-recurrence-children.html Diseases, Conditions, Syndromes Wed, 28 Nov 2012 17:00:10 EST news273344123 Twenty percent of young people born with HIV in the United States don't know they're infected when they have sex for the first time, according to a new study released Friday. http://medicalxpress.com/news/2012-11-youth-hiv-unaware-first-time-sex.html HIV & AIDS Sat, 10 Nov 2012 05:50:28 EST news271749017 In South Africa, HIV-infected men who are receiving treatment with anti-HIV drugs (antiretroviral therapy) are almost a third more likely to die than HIV-positive women who are receiving similar treatment: however, these differences are likely to be due to gender differences in death rates in the general population rather than related to HIV, according to a study by a team of international researchers published in this week's PLOS Medicine. http://medicalxpress.com/news/2012-09-mortality-hiv-positive-south-african-men.html HIV & AIDS Tue, 04 Sep 2012 17:00:02 EST news265972579 A new pill to treat HIV infection—combining two previously approved drugs plus two new ones—has been approved for adults living with the virus that causes AIDS, US regulators said Monday. http://medicalxpress.com/news/2012-08-fda-in-hiv-combination-pill.html HIV & AIDS Mon, 27 Aug 2012 17:58:59 EST news265309134 The HIV drugs known as CCR5 antagonists may also help prevent aggressive breast cancers from metastasizing, researchers from the Kimmel Cancer Center at Jefferson suggest in a preclinical study published in a recent issue of Cancer Research. http://medicalxpress.com/news/2012-06-hiv-drug-metastatic-breast-cancer.html Cancer Wed, 06 Jun 2012 15:27:01 EST news258215206 Pre-birth exposure to the anti-HIV drug tenofovir does not adversely affect pregnancy outcomes and does not increase birth defects, growth abnormalities, or kidney problems in infants born to African women who are HIV positive, supporting the use of this drug during pregnancy, according to a study by a team of international researchers published in this week's PLoS Medicine. http://medicalxpress.com/news/2012-05-anti-hiv-drug-tenofovir-safe-pregnancy.html HIV & AIDS Tue, 15 May 2012 17:00:11 EST news256312370 The first drug shown to prevent HIV infection won the endorsement of a panel of federal advisers Thursday, clearing the way for a landmark approval in the 30-year fight against the virus that causes AIDS. http://medicalxpress.com/news/2012-05-fda-panel-pill-block-hiv.html HIV & AIDS Fri, 11 May 2012 04:35:14 EST news255929707 California will test an HIV-prevention pill in an attempt to slow the spread of the disease in the state, researchers announced Tuesday. http://medicalxpress.com/news/2012-04-pill-block-hiv-slated.html HIV & AIDS Mon, 23 Apr 2012 05:30:23 EST news254377815 French pharmaceutical giant Sanofi has signed a partnership with India's Hetero to manufacture cheap anti-HIV drugs in South Africa, the company said on Friday. http://medicalxpress.com/news/2012-03-sanofi-teams-india-cheap-arvs.html Medications Fri, 30 Mar 2012 13:16:27 EST news252332179 Researchers from Boston University School of Medicine (BUSM) and Fenway Health have found that highly active antiretroviral therapy (HAART) does not completely suppress HIV in the semen of sexually active HIV-infected men who have sex with men (MSM).
