Self-monitoring helps reduce high-risk behavior among HIV-positive people
There are many effective, albeit expensive, intervention programs aimed at encouraging HIV-positive people to practice less risky behavior. But a new UCLA AIDS Institute study has found that self-monitoring by these patients is not only an effective strategy but is inexpensive and easy to implement as well. view more (2007-07-09)
Measles Vaccinations Need to be Repeated to Protect HIV-Infected Children
HIV-infected children may require repeat measles vaccination for protection, according to new research from the Johns Hopkins Bloomberg School of Public Health and other institutions. view more (2007-07-18)
Discovery of the origin of the Simian Immunodeficiency Virus (SIV) in the chimpanzee
The origin of HIV-1 (human immunodeficiency virus-1), responsible for the global Aids pandemic, has been a live issue in the scientific community for many years. It is now recognized that HIV-1 in the human population results from cross-species transmission of SIVcpz, from chimpanzees (Pan troglodytes troglodytes) to humans, most likely through... view more...

A new step towards an AIDS vaccine
Progressive disease after HIV infection is inversely correlated with the presence of plasmacytoid dendritic cells (pDCs), a subset of the dendritic cell family and the major producers of type 1 interferon in the body. view more (2005-10-14)
Well-armed immune cells help long-term nonprogressors contain HIV
To help develop an effective HIV vaccine, researchers are trying to better understand how the immune systems of a small minority of HIV-infected people known as long-term non-progressors (LTNPs) contain the virus naturally. view more (2008-12-05)
To slow AIDS in Russia, treat HIV-positive addicts, Stanford study says
The key to combating AIDS in Russia may be to treat HIV-infected drug users. A new model estimating the spread of HIV in Russia suggests that treating injection drug users with antiretroviral medication will slow transmission of the virus among the general population. view more (2006-11-10)
A low prevalence of H pylori in HIV-positive patients
Helicobacter pylori has been extensively studied and proven to be the main cause of chronic gastritis and peptic ulcer in the HIV-negative population. view more (2007-10-17)
Why are so few HIV/AIDS trials conducted in Africa?
People in sub-Saharan Africa carry the heaviest burden of HIV and AIDS, yet very few trials have been conducted on the African continent over the past two decades, say researchers in this week's BMJ. view more (2005-09-30)
Efficacy Of The Cognitive Behavioural Group Psychotherapy For HIV-Infected Patients
A group of investigators of the University of Barcelona have reported on the value of a group psychotherapy program in HIV-1 infected patients. Most HIV-infected patients attending a consultation-liaison psychiatry service show symptoms of anxiety and depression. The present study sought to evaluate the immediate and long-term efficacy of a... view more... (2002-03-19)
The origins of HIV: Did flies enable HIV to jump from chimps to humans?
BLOODSUCKING flies common all over the world may have begun the HIV epidemic by spreading the virus from chimpanzees to humans. That`s the latest challenge to the established theory that game hunters became infected when HIV-laden chimpanzee blood got into open wounds. Most bloodsucking insects pose... view more...

MicroRNAs help control HIV life cycle
Scientists at Burnham Institute for Medical Research (Burnham) have discovered that specific microRNAs (non-coding RNAs that interfere with gene expression) reduce HIV replication and infectivity in human T-cells. view more (2009-06-26)
Blacks hit hardest by HIV infection among nation's young adults
HIV infection is significantly more common among non-Hispanic blacks than it is among any other young adult racial or ethnic group in the United States, according to the first study drawn from the nation's general youth population. view more (2006-06-06)
Weighing costs, benefits of HIV treatments
Prevention versus treatment? Cost versus efficacy? So go two of the dilemmas looming over Dartmouth's Paul E. Palumbo, M.D., and his fellow researchers in the race to fight HIV and other infectious diseases in the developing world - especially among women and their young children. view more (2009-09-16)
Immune exhaustion in HIV infection
As HIV disease progresses in a person infected with the HIV virus, a group of cells in the immune system, the CD8+ T lymphocytes, become "exhausted," losing many of their abilities to kill other cells infected by the virus. view more (2008-05-06)
If started early, HIV treatment reduces death rates toward background levels in African countries
Mortality rates of people starting HIV treatment in four African countries approach those of the general population over time, provided that treatment is started before the immune system has been severely damaged, according to research published this week in the open-access journal PLoS Medicine. view more (2009-04-28)
Reduction In HIV-1 Incidence Among Rural Ugandans Gives Hope To Other African Countries (pp 3, 41, 78)
A study in this week's issue of THE LANCET highlights a reduction in both HIV-1 incidence (the number of new cases) and prevalence (the number of cases in the population) from the beginning to the end of the past decade among a rural Ugandan population. Authors of the study conclude that the results could offer hope for other sub-Saharan countries... view more... (2002-07-03)
Women in India abused by husbands at far greater risk for HIV infection
India is home to the third-largest number of human immunodeficiency virus (HIV) cases in the world and, as in the U.S. and many African nations, the rate of infection among women continues to rise faster than that among men. view more (2008-08-13)
PrEP strategy could dramatically slow the spread of HIV
Giving a daily antiretroviral pill to people to prevent HIV could profoundly slow the spread of the infection in sub-Saharan Africa, where it is a full-blown epidemic, University of Pittsburgh School of Medicine researchers report. view more (2007-09-19)
Asthma risk increases in children treated for HIV
Children whose immune systems rebound after treatment with potent anti-viral drugs for HIV infection face an increased risk of developing asthma, said a federally funded consortium of researchers led by those from Baylor College of Medicine in a report that appears online in the Journal of Allergy and Clinical Immunology. view more (2008-07-02)
Detecting transmissibility of avian influenza virus in human households
Recent outbreaks of emerging diseases such as SARS and H5N1 avian influenza have underlined the fact that animal pathogens may acquire the ability to spread efficiently in humans - but as yet have not. view more (2007-07-26)
