Commonly used pneumococcal polysaccharide vaccines do not appear to be effective for preventing pneumonia, found a study by a team of researchers from Switzerland and the United Kingdom.

Hepatitis A infections, usually transmitted via contaminated food, can cause debilitating illness, but protection afforded by the hepatitis A vaccine last more than a decade, a new study shows.

Giving antibiotics to patients in intensive care units as a precaution saves lives, according to a major Dutch study published Wednesday.
New Way Men Can Transmit HIV to Women

Researchers at Northwestern University have discovered a critical new way a man can transmit the HIV virus to a woman.
Scientists had long believed that the normal lining of the female vaginal tract was an effective barrier to invasion of the HIV virus during sexual intercourse. They thought the large HIV virus couldn't penetrate the tissue.
But new research from Northwestern University's Feinberg School of Medicine has shown for the first time that the HIV virus does indeed penetrate a woman's normal, healthy genital tissue to a depth were it can gain access to its immune cell targets.
Antibody fights AIDS-like disease in monkeys

An antibody treatment has rejuvenated the immune systems of macaques infected with a virus called SIV, allowing the monkeys to fend off the symptoms of an AIDS-like disease for months. SIV is studied as a model for HIV infection in humans, and the therapy could be tested in clinical trials of HIV-infected patients as soon as next year, pending approval by regulators.
"Zinc Zipper" Plays Key Role in Hospital-acquired Infections

Hospital-acquired infections that are resistant to traditional antibiotic treatment have become increasingly common in recent years, confounding health care professionals and killing thousands of patients in the U.S. alone.
Now, in studies that could lead to new ways to prevent this growing public health danger, a team of University of Cincinnati (UC) researchers is exploring a “zinc zipper” that holds bacterial cells together and plays a key role in such infections.

HIV testing on the cheap! ...but no one's interested.

The standard HIV test, such as a patient might receive in a hospital in New York or Paris, is generally too expensive for AIDS prevention organizations in Africa. However, new developments that could make HIV testing more feasible are not garnering enough interest from private investors.
These tests are not limited to determining who is infected and who isn't. For example, CD4 tests, which measure HIV-indicative changes in the patient's cell receptors, are used to tell how far the disease has progressed, which can help doctors give their patients the most effective drug regimens
Extended Drug Therapy for Hepatitis Is Challenged

Patients who do not initially respond to standard drug therapy for treatment of hepatitis C are unlikely to respond to long-term maintenance therapy as well, according to a new study.

The U.S. Food and Drug Administration (FDA) has granted SELZENTRY™ (maraviroc) full (traditional) approval for use in treatment-experienced adults with CCR5-tropic HIV-1 in combination with other antiretrovirals. SELZENTRY was originally granted accelerated conditional approval in August 2007 based on 24-week data from pivotal Phase 3 studies. SELZENTRY now becomes the latest fully approved treatment for HIV.
“New, effective and well-tolerated treatment options are critical for treatment-experienced persons living with HIV infection,” said W
Scientists Discover 21st Century Plague

Bacteria that can cause serious heart disease in humans are being spread by rat fleas, sparking concern that the infections could become a bigger problem in humans. Research published in the December issue of the Journal of Medical Microbiology suggests that brown rats, the biggest and most common rats in Europe, may now be carrying the bacteria.
Since the early 1990s, more than 20 species of Bartonella bacteria have been discovered
Doctors say marrow transplant may have cured AIDS

An American man who suffered from AIDS appears to have been cured of the disease twenty months after receiving a targeted bone marrow transplant normally used to fight leukemia, his doctors said.
While researchers--and the doctors themselves--caution that the case might be no more than a fluke, others say it may inspire a greater interest in gene therapy to fight the disease that claims 2 million lives each year. The virus has infected 33 million people worldwide.

Chemical from Medicinal Plants May Be Used to Fight HIV
piggy submitted, created time 1 month 3 weeks (www.sciencedaily.com)
Like other kinds of cells, immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division. As a result, the cell changes in many ways, and its disease fighting ability is compromised.
But a new UCLA AIDS Institute study has found that a chemical from the Astragalus root, frequently used in Chinese herbal therapy, can prevent or slow this progressive telomere shortening, which could make it a key weapon in the fight against HIV
Merck vaccine protects men from wart virus, too

Bone marrow transplant suppresses AIDS in patient

A bone marrow transplant using stem cells from a donor with natural genetic resistance to the AIDS virus has left an HIV patient free of infection for nearly two years, German researchers.
The patient, an American living in Berlin, was infected with the human immunodeficiency virus that causes AIDS and also had leukemia. The best treatment for the leukemia was a bone marrow transplant, which takes the stem cells from a healthy donor's immune system to replace the patient's cancer-ridden cells.

Earlier HIV treatment can save more lives

Treating HIV earlier can increase a patient’s survival chances, a new study of more than 8,000 HIV patients shows. The findings suggest doctors should rethink the standard practice of HIV treatment, a team reports at a meeting of microbiologists and infectious disease researchers
