An experimental vaccine seems to give monkeys extended protection from an HIV-like infection -- by "waking up" an arm of the immune system that vaccines normally do not.
Experts cautioned that animal research often does not pan out in humans. The decades of work toward an HIV vaccine has been a clear example. But, researchers said, this vaccine works differently, targeting two "arms" ...
Researchers have reformulated an HIV medication into a version they hope can eventually be taken as infrequently as once a year.
The work is only in the early stages, having been studied in lab animals. But the goal is to create an HIV drug that can be injected annually -- offering protection from infection or control of the virus in people who already have it.
Young people with HIV have much lower rates of viral suppression than adults with the AIDS-causing virus, a new U.S. study finds.
Viral suppression means that HIV has been reduced to undetectable levels. Maintaining viral suppression for at least six months prevents the sexual transmission of HIV and helps people with the virus remain healthy.
Too few Americans are getting tested or treated for HIV, a new government report shows.
"The time is now to end HIV in America. We have the right tools, the right data and the right leadership to get this done," said Dr. Robert Redfield, director of the U.S. Centers for Disease Control and Prevention.
"Those living with HIV are our best teachers. They are key to helping us r...
Giving HIV-suppressing medications to infected babies within hours of birth is feasible and might help doctors eliminate hidden reservoirs of the virus, new research suggests.
"Strategies to test and treat infants immediately after birth may improve outcomes," said study senior author Dr. Mathias Lichterfeld. He's an associate physician of infectious diseases at Brigham and Women's H...
Children born to women who take the HIV drug efavirenz during pregnancy have a higher risk of small head size -- a birth defect known as microcephaly -- compared to babies exposed to other HIV drugs in the womb, new research shows.
Prenatal exposure to the drug was also linked to developmental delays in children.
But one U.S. expert said the new data shouldn't alarm most HIV...
Needle exchange programs in two large U.S. cities prevented thousands of new HIV infections and saved hundreds of millions of dollars, researchers say.
Needle, or syringe, exchange programs prevented nearly 10,600 new cases of HIV in Philadelphia and almost 1,900 new cases of HIV in Baltimore over 10 years, leading to significant savings for the cities, the new study found.
Women with HIV experience menopause years sooner than other women -- about three years earlier, on average, a new study finds.
Treatment advances are keeping people with the virus alive longer, and those who adhere to therapy are expected to live into their mid-70s or longer. That means they'll face aging issues that affect sexual and reproductive health, including menopause, the stud...
There's good news for people with HIV who get a kidney from a donor who also has HIV: A new study reports high five-year survival rates.
"A growing number of people with HIV have a need for kidney transplants. Unfortunately, these gifts of life are too often in short supply," said Dr. Anthony Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases.
People with HIV have a greatly increased risk of a common heart rhythm disorder that's a leading cause of stroke, a new study shows.
The increased risk of atrial fibrillation (AF) from HIV is similar to or higher than known risk factors such as diabetes and high blood pressure, according to researchers from the University of California, San Francisco (UCSF).
Teens who feel connected with others at home and school have fewer serious health problems and risks as young adults, a new study suggests.
Young adults who had higher levels of connectedness -- feeling engaged, supported and cared for at home and at school -- when they were teens were as much as 66% less likely to have mental health problems, to experience violence, to take sexua...
Fewer than 4 in 10 Americans have ever heeded federal government recommendations to be tested for HIV, health officials reported Thursday.
"Getting tested for HIV is quicker and easier than ever before -- and when you take the test, you take control," said Dr. Eugene McCray, director of the Division of HIV/AIDS Prevention at the U.S. Centers for Disease Control and Prevention. The age...
A daily pill that can block transmission of HIV should be prescribed to people at high risk of infection with the AIDS-causing virus, according to a highly influential panel of experts.
The treatment -- called pre-exposure prophylaxis (PrEP) -- has proven highly effective at preventing HIV spread in clinical trials, an evidence review by the U.S. Preventive Services Task Force (USPST...
Day-to-day struggles prevent many American women with HIV from taking medicines to suppress the AIDS-causing virus, a new study shows.
"Survival is a priority over putting a pill in your mouth for a number of our participants, and that is the public health challenge we must address," said study first author Dr. Seble Kassaye, an associate professor at Georgetown University Medical Cen...
Even if they never use a condom during sex, gay men whose HIV is undetectable due to ongoing antiretroviral treatment cannot infect their male partner, new research reveals.
"Whether men who are in monogamous relationships in these circumstances chose to use or not to use condoms is up to them, but there is no need to do so to prevent HIV transmission to the negative partner," said the ...
When it coincides with HIV, depression appears associated with an increased risk of death, a new study says.
Researchers analyzed data from the U.S. Veteran's Aging Cohort Study to compare the risk of death among those with and without depression, and the association between depression and death among those with and without HIV, the virus that causes AIDS.
The battle against new HIV infections has lost some steam in recent years, a new report shows.
After about five years of significant declines, the number of new HIV infections began to level off in 2013, at about 39,000 infections per year, the U.S. Centers for Disease Control and Prevention found.
Why the slowing? Effective HIV prevention and treatments are not reaching tho...
As a highlight of his 2019 State of the Union address, President Donald Trump on Tuesday announced his administration's plan to rid the United States of new transmissions of HIV by 2030.
"In recent years we have made remarkable progress in the fight against HIV and AIDS," Trump told the nation. "Scientific breakthroughs have brought a once-distant dream within reach. My budget will a...
A large number of U.S. cancer patients with hepatitis B and C don't know they have the virus, which can cause life-threatening complications during some cancer treatments, researchers say.
The findings suggest screening for hepatitis B and C may be appropriate in community cancer clinics, according to investigators from the SWOG Cancer Research Network, an international group funded b...
People who take prescription opioid painkillers are at increased risk for pneumonia, especially those with HIV, a new study suggests.
The findings support concerns that prescription opioids can weaken the immune system. Doctors who prescribe opioids need to reduce patients' risk of pneumonia through vaccination and by encouraging them to stop smoking, the researchers said.
The future of medicine may be here: Researchers at the Massachusetts Institute of Technology say they've developed an ingestible capsule that can be monitored outside the body for health data, using Bluetooth wireless technology.
The capsule could deliver drugs as well as sense the condition of its surroundings in the gut, including infections or allergic reactions, the researchers e...
An experimental vaginal ring meant to prevent pregnancy and HIV looks safe, according to an early stage study.
The dual-purpose ring releases the antiretroviral drug dapivirine and the contraceptive hormone levonorgestrel, said researchers led by Dr. Sharon Achilles, of the University of Pittsburgh School of Medicine.
"We are very encouraged by our findings in this first-in...
A combination of two HIV-fighting antibodies can suppress the virus in some patients, even after they stop standard drugs, a preliminary trial has shown.
Researchers found that among 11 HIV patients given the antibody combo, nine maintained complete suppression of the virus after going off their medication regimen. The benefit typically lasted about five months.
