HIV infection
Los Angeles, London, New Delhi, Singapore and Washington DC (May 29, 2009) The FDA is ignoring critical information in deciding whether to approve an over-the-counter, rapid HIV test for home use, according to a recent article in the journal Medical Decision Making (MDM) which is published by SAGE.
The Centre for Epidemiological Studies into Sexually-Transmitted Diseases and AIDS in Catalonia (CEEISCAT) started a pioneering study in Spain in 2005 to look into the prevalence of sexually-transmitted diseases (STDs) among female sex workers (SWs). The objective was to monitor the rates of infection with both HIV and other diseases over time, as well as the prevalence of risky behaviour.
NEW YORK (May 19, 2009) -- Researchers from Weill Cornell Medical College have published results showing that a new contraceptive device may also effectively block the transmission of the HIV virus. Findings show that the device prevents infection by the HIV virus in laboratory testing. The promising results are published in the most recent issue of the journal AIDS.
A research team may have broken the stubborn impasse that has frustrated the invention of an effective HIV vaccine, by using an approach that bypasses the usual path followed by vaccine developers.
STANFORD, Calif. - HIV-positive patients who don't seek medical attention until they have a serious AIDS-related condition can reduce their risk of death or other complications by half if they get antiretroviral treatment early on, according to a new multicenter trial led by researchers at the Stanford University School of Medicine.
A recently completed international multi-center clinical trial has found that acyclovir, a drug widely used as a safe and effective treatment to suppress herpes simplex virus-2 (HSV-2), which is the most common cause of genital herpes, does not reduce the risk of HIV transmission when taken by people infected with both HIV and HSV-2.
Infection with anal human papillomavirus (HPV), a virus that can cause anal and cervical cancers, is associated with a higher risk of new HIV infection in previously HIV-negative men who have sex with men (MSM), according to new UCSF research.
Scientists may need to rethink the design of drugs meant to block HIV from infecting human cells, according to a study that appears in the May 1st issue of the journal Cell, a Cell Press publication. That's because the new report shows that HIV doesn't enter cells in the way that experts had generally assumed it did.
LINTHICUM, MD, April 26, 2009-Two studies presented at the 104th Annual Scientific Meeting of the American Urological Association (AUA) show that adult circumcision reduces the risk of contracting the human immunodeficiency virus (HIV) and the risk of coital injury!!--without reducing pleasure or causing sexual dysfunction.
The "humanized mouse" developed by Dr. J. Victor Garcia-Martinez has allowed the University of Texas Southwestern physician-scientist to conduct HIV/AIDS studies that would have been impossible without such a small animal model of HIV infection. The virus only infects humans and chimpanzees, which are protected as endangered species.
The AIDS-causing HIV specifically counteracts the mechanisms of human cells that protect these against viral infections - a special viral protein marks protective cellular proteins for their rapid destruction and thus diminishes the cell's supply. A team of researchers in Heidelberg under supervision of virologist Dr.
Damage to patients' immune systems is happening sooner now than it did at the beginning of the HIV epidemic, suggesting the virus has become more virulent, according to a new study in the May 1, 2009 issue of Clinical Infectious Diseases, now available online.
Seattle - A study showing improved survival of starting antiretroviral treatment earlier than current U.S. recommendations is being reported in the April 30 issue of the New England Journal of Medicine. The study found that not starting HIV patients at a CD4 count greater than 500 cells per cubic millimeter increased risk of death by 94 percent.
Many scientists believe a vaccine that prevents HIV infection will need to stimulate the body to make neutralizing antibodies, infection-fighting proteins that prevent HIV from entering immune cells. Previous research has shown that some individuals who control HIV infection without medication naturally produce antibodies able to neutralize diverse strains of HIV.
March 5, 2009 -- A clinical trial involving more than 3,000 women in the U.S. and southern Africa demonstrates for the first time the promise of a vaginal microbicide gel for preventing HIV infection in women.
