Researchers disprove long-standing belief about HIV treatment

Researchers at Wake Forest University Baptist Medical Center have disproved a long-standing clinical belief that the hepatitis C virus slows or stunts the immune system's ability to restore itself after HIV patients are treated with a combination of drugs known as the 'cocktail.'

Life expectancy of HIV patients increases

HIV-infected patients in high income countries are living some 13 years longer thanks to improvements in combination antiretroval therapy (cART), according to new research by the University of Bristol published in a HIV Special Issue of The Lancet today.

HIV-I damages the immune system early than originally thought

New research into the earliest events occurring immediately upon infection with HIV-I shows that the virus deals a stunning blow to the immune system earlier than was previously understood. According to scientists at Duke University Medical Center, this suggests the window of opportunity for successful intervention may be only a matter of days - not weeks - after transmission, as researchers had previously believed.

Tired B cells hamper immune response to HIV

Recent studies have shown that HIV causes a vigorous and prolonged immune response that eventually leads to the exhaustion of key immune system cells--CD4+ and CD8+ T-cells--that target HIV.

FDA approves Energex Systems non-drug therapy for HIV research

Energex Systems, Inc. announced today that it has been granted approval from the Federal Food and Drug Administration (FDA) to utilize its experimental HemoModulation therapy in a clinical trial of HIV infected patients. The purpose of the study will be to demonstrate safety and monitor viral load changes in patients who are not yet eligible for antiviral drug therapy.

Discover of key patterns in gene packaging

Although every cell of our bodies contains the same genetic instructions, specific genes typically act only in specific cells at particular times. Other genes are "silenced" in a variety of ways. One mode of gene silencing depends upon the way DNA, the genetic material, is packed in the nucleus of cells.

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.

Yeast-based vaccine induces immune responses and reduces tumor size in mice

Scientists have found that vaccination with a heat-killed, non-toxic yeast that is genetically engineered to manufacture a common tumor protein can induce specific and repeated anti-tumor immune responses in mice.

Zinc finger technology brings personalized HIV therapy a step closer

Researchers at the University of Pennsylvania School of Medicine and collaborators are using minute, naturally occurring proteins called zinc fingers to engineer T cells to one day treat AIDS in humans.

Patient's own infection-fighting T cells put late-stage melanoma into long-term remission

Researchers describe the first successful use of a human patient's cloned infection-fighting T cells as the sole therapy to put an advanced solid-tumor cancer into long-term remission. A team led by Cassian Yee, M.D., an associate member of the Clinical Research Division at Fred Hutchinson Cancer Research Center, reports these findings in the June 19 issue of the New England Journal of Medicine.

Scientists cure advanced skin cancer with body's own cells

Scientists in the U.S. are claiming they have cured advanced skin cancer by using the patient's own cells.

Without increased funding, California's dominance and public health are threatened, according to new report

The California Healthcare Institute (CHI) and PricewaterhouseCoopers (PwC) today released a report, "The National Institutes of Health: Fueling Healthcare Innovation in California," urging legislators to support increased funding for the National Institutes of Health (NIH) - the backbone of the biomedical industry in California, which employs more than 267,000 people in high wage jobs.

Possible biological explanation for C-Section-linked allergies and asthma found

Scientists believe they may have identified a biological explanation for the link between cesarean-section delivery and risk of allergy and asthma in childhood. They will present their findings at the American Thoracic Society's 2008 International Conference in Toronto on Tuesday, May 20.

Farming mothers may help children beat allergies

Mothers exposed to farms, particularly to barns and farm milk, while pregnant confer protection from allergies on their newborns, according to a group of German researchers, who will present their findings at the American Thoracic Society's 2008 International Conference in Toronto on Wednesday, May 21.

Blood-free monitoring as good as blood tests in predicting the course of AIDS

Researchers at the University of Pennsylvania School of Medicine have shown that monitoring treatment adherence to AIDS therapy is a simple blood-free way to monitor risk of disease progression. The international study was published in the May issue of the journal PLoS Medicine.

Monitoring whether patients take medicines can help anticipate HIV treatment failure in Africa

Information on how reliably people take their anti-HIV medicines can help identify those whose treatment will succeed or fail. Monitoring this information, which can be obtained directly from pharmacy records, works at least as well as performing blood tests that track the medicine's effect on the immune system, according to research published in PLoS Medicine by Gregory Bisson, Jean Nachega and colleagues at the University of Pennsylvania, Johns Hopkins Bloomberg School of Public Health, and the University of Cape Town.

Researchers discover 'reservoir' that allows HIV to remain infectious despite treatment

Researchers at Brigham Young University and the Johns Hopkins School of Medicine have discovered a human cell "reservoir," called follicular dendritic cells, that allows HIV to stay in an infectious state and not respond to antiretroviral drugs, the Deseret Morning News reports.

GeoVax Labs to launch phase II trials of HIV vaccine candidate

The Atlanta-based biotechnology firm GeoVax Labs plans to launch Phase II clinical trials of its experimental HIV vaccine this summer, company officials recently announced, the Atlanta Journal-Constitution reports (Hendrick, Atlanta Journal-Constitution, 5/8).

Tests monitoring viral loads, CD4+ count do not significantly affect survival rates among HIV-positive people

Survival rates among HIV-positive people who undergo routine viral load and CD4+ T cell counts were nearly the same as those who do not receive the tests, according to a study published on Friday in the journal Lancet, the CP/Google.com reports (CP/Google.com, 4/24).

Monitoring AIDS treatment by physical symptoms is effective

When millions of HIV-infected people in poor countries began receiving advanced drug therapies, critics worried that patient care would suffer because few high-tech laboratories were available to guide treatments.
