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.

Dermatologists link family history to shingles susceptibility

Researchers at The University of Texas Medical School at Houston have identified family history as one reason why some people might be more susceptible to shingles, a severe skin condition. Their findings are published in the May 19 issue of Archives of Dermatology.

Abnormal "editing" of gene messages may cause Lupus

Researchers at Wake Forest University have uncovered evidence that the abnormal "editing" of gene messages in a type of white blood cell may be behind the development of lupus. Scientists hope the finding will lead to earlier diagnosis, a way to monitor patients' response to therapy and possibly a new way to treat the disease.

Minocycline may find new life as a stroke treatment

An old intravenous antibiotic may have new life as a stroke treatment, researchers say. Minocycline appears to reduce stroke damage in multiple ways - inhibiting white blood cells and enzymes that, at least acutely, can destroy brain tissue and blood vessels, respectively, says Dr. David Hess, chair of the Department of Neurology in the Medical College of Georgia School of Medicine.

An improved gene therapy agent from University of Florida

Replacing one amino acid on the surface of a virus that shepherds corrective genes into cells could be the breakthrough scientists have needed to make gene therapy a more viable option for treating genetic diseases such as hemophilia, University of Florida researchers say.

Investigational smallpox drug may treat adenovirus infections in humans

Scientists at Saint Louis University have made two key discoveries that could lead to the first-ever human testing of a drug to target the adenovirus, which causes a number of severe upper-respiratory infections and is one of many viruses that causes the common cold.

Rochester vaccine triggers immune response, prevents Alzheimer's

A vaccine created by University of Rochester Medical Center scientists prevents the development of Alzheimer's disease-like pathology in mice without causing inflammation or significant side effects.

Nasal gel to fight superbug MRSA

British scientists are well on the way to developing a new drug to fight the 'superbug' Methicillin-resistant Staphylococcus aureus (MRSA).

First pre-pandemic bird flu vaccine available in Europe

The approval for a licence from the European Commission will place Glaxo ahead of rivals in the vaccine fields and the company says it has already received orders from some governments such as the U.S., Switzerland and Finland.

Stress during pregnancy increases the risk of child developing asthma

New research from the U.S. suggests that women who suffer from stress during pregnancy may increase the risk of their child developing allergies.

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.

Effectiveness of antiretroviral therapy causing 'complacency' among high-risk groups

HIV/AIDS clinicians and scientists have been "witness to a transformation in disease management that is virtually unprecedented in the history of medicine," Mark Wainberg, director of McGill University's AIDS Centre at Jewish General Hospital, and Julio Montaner, director of the BC Centre for Excellence in HIV/AIDS, write in a National Post opinion piece.

Men at increased risk of death from pneumonia compared to women

Men who come to the hospital with pneumonia generally are sicker than women and have a higher risk of dying over the next year, despite aggressive medical care, according to a study being presented Tuesday, May 20, at the 104th International Conference of the American Thoracic Society. Scientific sessions are scheduled May 16 to 21 in Toronto.

Personalized therapy for asthma and chronic obstructive pulmonary disease could soon be here

Researchers at Washington University School of Medicine in St. Louis have defined a new type of immune response that is activated in patients with severe asthma and COPD (chronic obstructive pulmonary disease). Their discovery could dramatically improve diagnosis and treatment of patients with chronic inflammatory lung disease.

DNA vaccines boosted by dendritic cells

The concept sounds ideal: vaccines made of DNA that could be taken in by other cells and give instructions for how to fight off different diseases. The reality, however, has fallen short. Although DNA vaccines have been around for about 15 years and shown lots of promise for HIV, SARS and influenza vaccines during preclinical testing in mice, researchers have yet to make them potent enough to be helpful in humans.

Length of telomeres in blood cells tied to breast cancer survival rates

Researchers at Umea University in Sweden have shown that the length of telomeres in blood cells in newly diagnosed breast cancer patients is tied to survival rates. The study, published in the journal Cancer Research, was carried out by a research team headed by Professor Goran Roos at the Department of Medical Bioscience, Pathology.
