An experimental AIDS drug taken in combination with a recently approved medication dramatically reduced the amount of virus in the blood of patients with a history of drug resistance, according to two international studies published today. The studies reported that up to 18% more drug-resistant patients saw the amount of virus in their blood drop to undetectable levels after 24 weeks compared with those taking a standard drug regimen.

The middle-aged woman was desperately ill. Brought by an anxious daughter to the emergency room at St. Joseph Medical Center in Burbank, she was nearly in a coma, her brain swelling with meningitis. Doctors swiftly put her on two antibiotics that for years have been highly effective against the disease. But she failed to improve, and lab tests showed she had a form of meningitis that resists both drugs.

At least one in every four San Franciscans newly infected with HIV, the virus that causes AIDS, contracts a form that is resistant to one or more of the commonly used AIDS drugs, researchers said here Saturday. As a result of this resistance, it takes at least three times as long to bring these infections under control, and more complicated drug regimens are often required, said Dr. Frederick M. Hecht of UC San Francisco.

The young Army medic would not stop bleeding. He had been put on a powerful regimen of antibiotics by doctors aboard the hospital ship Comfort in the Persian Gulf. But something was wrong. He was in shock and bleeding from small pricks where nurses had placed intravenous lines. Red, swollen tissue from an active bacterial infection was expanding around his abdominal wound. His immune system was in overdrive. How odd, thought Dr. Kyle Petersen, an infectious disease specialist.

Patterns of antibiotic overuse vary in the U.S. vary by region, with residents of some Southeastern states taking about twice as many antibiotics per capita as residents in some Western states. According to the Washington-based Center for Disease Dynamics, Economics and Policy , Kentucky, West Virginia, Tennessee, Mississippi and Louisiana were the states with the highest rates of antibiotic use in 2010. Those states had more than one antibiotic prescription per capita in 2010. The states with the lowest use of antibiotics that year were Alaska, Hawaii, California, Oregon and Washington, with just over one prescription for every two people. Overall, the rate of antibiotic prescriptions in the U.S. declined from 966 prescriptions for each 1,000 residents in 1999 to 801 in 2010.

AVOIDING the use of antibiotics in food animals appears to reduce drug resistance in humans, according to a study published online last week in the journal Clinical Infectious Diseases. The study involved the use of antibiotics called fluoroquinolones in Australian poultry. Australia restricts use of the antibiotics in animal husbandry because the practice is thought to contribute to drug resistance in people who contract bacterial infections from eating contaminated food.

Antibiotics can be your best friend, especially when infection or traveler's diarrhea strikes in the middle of a glorious vacation. It's crucial to know which antibiotics are worth toting, how they can ease symptoms of illness and when it's wise to pop a pill. In some cases, it might even be before symptoms appear. Infectious illnesses are common in travelers but account for only 1% to 3% of deaths, says Dr. Jay Keystone, a travel medicine specialist at the University of Toronto and Toronto General Hospital in Canada who published a review of antibiotics for travelers in the February issue of the journal Current Infectious Disease Reports.

About half of all adults being treated for HIV infection in the United States have strains of the virus that are resistant to some of the standard drug therapies, according to a study released Tuesday. The study is the first large-scale national survey to reveal the drug resistance. Previous drug-resistance research, physicians said, focused only on smaller groups of patients. "This is very discouraging," said Dr. Samuel Bozette of the San Diego VA Medical Center, a co-leader of the study.

Flu researchers Yoshihiro Kawaoka and Ron Fouchier found themselves in the middle of a firestorm when, in 2011, they reported how, in separate experiments, they had created mutant strains of the H5N1 bird flu that were able to pass easily between ferrets -- mammals often studied to understand how flu passes between people. On Wednesday, in a letter published in two leading scientific journals, the virologists and 22 coauthors explained why they are now planning to conduct similar experiments with another deadly bird flu: H7N9, which is circulating in China and has thus far killed 43 of the more than 130 people known to have been infected with it. "To fully assess the potential risk associated with these novel viruses, there is a need for further research," they wrote in the journals Science and Nature . Scientists are concerned about H7N9 flu for a variety of reasons. So far, H7N9 hasn't been as deadly as H5N1, which as of early July had killed 377 people, according to the World Health Organization (nearly 60% of the known cases.)

Acnemedications and treatments fill drug store shelves, but some acne sufferers may have a tough time discerning which are the best to use. A paper published online in the journal the Lancet finds that certain studies on acne remedies are few and far between. In a seminar in the journal researchers from the U.S. and the U.K. reviewed the current slate of treatments available, including topical treatments such as benzoyl peroxide, retinoids and topical antibiotics, and oral treatments such as antibiotics, contraceptives and isotretinoin (the last typically used to treat severe cases of acne)
