HIV causes specific subset of CD4+ T-cells to age rapidly: Study

In the early years of the AIDS epidemic, being infected with the virus that causes the disease was considered a virtual death sentence. But with the development of antiretroviral therapy, many with HIV are now living much longer. In fact, it is estimated that by 2015, about half of all HIV-positive individuals will be older than 50.

Researchers develop anti-HIV gene therapy for rendering T-cells resistant to infection

An innovative genetic strategy for rendering T-cells resistant to HIV infection without affecting their normal growth and activity is described in a paper published in Human Gene Therapy, a peer-reviewed journal published by Mary Ann Liebert, Inc. The paper is available free online.

Research findings reveal HIV's hiding spot, new way to stop the virus

HIV adapts in a surprising way to survive and thrive in its hiding spot within the human immune system, scientists have learned. While the finding helps explain why HIV remains such a formidable foe after three decades of research - more than 30 million people worldwide are infected with HIV - it also offers scientists a new, unexpected way to try to stop the virus.

Study: HIV-positive head and neck cancer patients respond well to radiation therapy treatments

HIV-positive head and neck cancer patients respond well to radiation therapy treatments and experience similar toxicity rates as non-HIV-positive patients, despite prior reports to the contrary, according to a study in the January issue of the International Journal of Radiation Oncology•Biology•Physics, an official journal of the American Society for Radiation Oncology.

Race and region play major role in health outcomes of people infected with HIV

Women, nonwhites, and people in the southern United States who were newly infected with HIV and followed for an average of four years experienced greater HIV/AIDS-related morbidity compared to men and people of other races living in other regions of the country. The findings, published in the February 15 issue of The Journal of Infectious Diseases, underscore the urgent need to improve the health of these populations in order to reduce HIV-related morbidity and mortality in the U.S.

Clinical studies by expert HIV clinicians suggest that HIV-TRePS may have clinical and economic benefits

Two multinational clinical studies indicate that the RDI’s system for predicting how HIV and AIDS patients will respond to different drugs could be a useful tool with potential clinical and economic benefits. The studies, published in the January issue of AIDS Patient Care and STDs, involved highly experienced physicians in the USA, Canada and Italy who used the system to help them select the optimum combination of HIV drugs for patients whose therapy was failing.

Earlier ART initiation should be highest priority for global expansion of HIV patient care

Earlier initiation of antiretroviral therapy should be the highest priority for global expansion of HIV patient care. This finding, from a paper published in this week's PLoS Medicine, should help resource-limited nations to phase in the implementation of the new 2010 WHO recommendations for HIV treatment. "Immediate scale-up of the entire WHO guideline package may be prohibitively expensive in some settings," said lead author Rochelle P. Walensky, MD, MPH of the Massachusetts General Hospital, Boston, USA.

Profectus' GENEVAX IL-12 pDNA adjuvant improves vaccine-induced response rate in Phase I HIV study

Profectus Biosciences, Inc., a leader in the development of therapeutic and preventive vaccines against infectious diseases and cancers, announced today that its GENEVAX™ IL-12 pDNA adjuvant has significantly improved the vaccine-induced response rate in a Phase I clinical study of an experimental DNA vaccine for the prevention of HIV infection.

CMS increases reimbursement rate for Cylex's immune cell function assay by 267%

Cylex Incorporated® today announced that the Centers for Medicare and Medicaid Services (CMS) nearly tripled the reimbursement for ImmuKnow®, the immune cell function assay FDA-cleared for the detection of cell-mediated immune response in populations undergoing immunosuppressive therapy for organ transplant. This significant increase was granted in a time when the overall CMS clinical fee schedule experienced a comprehensive decrease in laboratory reimbursement rates.

VIRxSYS presents study results of VRX1116 at HIV DART 2010

VIRxSYS Corporation, a privately held company developing vaccines and RNA therapies, today presented results from a study of VRX1116 at HIV DART 2010 in Los Cabos, Mexico, showing that vaccinated monkeys challenged with highly pathogenic simian immunodeficiency virus achieve sustained viral load reduction, preservation of the immune system and increased survival compared to controls.

Worm eggs may heal ulcerative colitis: Research

A new study involving a man who swallowed worm eggs to relieve symptoms of ulcerative colitis sheds light on how worms promote healing in the intestine. The study, published today in Science Translational Medicine, also identifies potential targets for more conventional ways of treating colitis, an inflammatory bowel disease.

SPARTAC study examines ways to limit immune system damage in HIV infection

For most people in high-income countries HIV is considered a chronic illness which can be managed with medication. But the virus still causes extensive damage to the immune system, and treatment with antiretrovirals is a lifelong commitment. Once started, usually within three to five years following infection, the course of treatment needs to be strictly followed and taken for life.

Not all HIV viruses are bad for the immune system

Mayo Clinic researchers have shown why, in a minority of HIV patients, immune function improves despite a lack of response to standard anti-retroviral treatment. In these cases, researchers say, the virus has lost its ability to kill immune cells. The findings appear in the online journal PLoS Pathogens.

Cytheris' combinational therapy demonstrates possible therapeutic strategy for PML

Cytheris SA, a clinical-stage biopharmaceutical company focused on research and development of new therapies for immune modulation, today announced the publication of a case study report based on successful treatment of Progressive Multifocal Leukoencephalopathy (PML) with combination therapy consisting of two investigational agents, Cytheris' recombinant human interleukin-7 (CYT107) and CMX001, an investigational, oral broad-spectrum antiviral drug (Chimerix, Research Triangle Park, NC) in the Journal of Antimicrobial Chemotherapy.

How HIV kills CD4 T cells

Researchers appear to have an explanation for a longstanding question in HIV biology: how it is that the virus kills so many CD4 T cells, despite the fact that most of them appear to be "bystander" cells that are themselves not productively infected. That loss of CD4 T cells marks the progression from HIV infection to full-blown AIDS, explain the researchers who report their findings in studies of human tonsils and spleens in the November 24th issue of Cell, a Cell Press publication.
