Children with HIV Score Below HIV-Negative Peers in Cognitive, Motor Function Tests

December 18, 2019

Children who acquired HIV in utero or during birth or breastfeeding did not perform as well as their peers who do not have HIV on tests measuring cognitive ability, motor function and attention, according to a report published online today in Clinical Infectious Diseases. The observational study included neuropsychological evaluations of 611 children in sub-Saharan Africa.

Efforts to End the HIV Epidemic Must Not Ignore People Already Living With HIV

Gay, Bisexual Men Increasingly Agree—HIV “Undetectable Equals Untransmittable”

December 05, 2019

Extensive evidence from HIV prevention research studies has firmly established that “Undetectable Equals Untransmittable,” or U=U. This means that people living with HIV who achieve and maintain an undetectable viral load—the amount of virus in their blood—by taking antiretroviral therapy (ART) as prescribed do not sexually transmit HIV to others.

Cerebral Organoid Model Provides Clues About How to Prevent Virus-Induced Brain Cell Death

November 26, 2019

Scientists have determined that La Crosse virus (LACV), which can cause inflammation of the brain in children, affects brain cells differently depending on their developmental stage. Neurons—the primary brain cells of the central nervous system—evolve from neural stem cells and during development “commit” to becoming neurons. A new National Institutes of Health study shows that uncommitted neural stems cells generally survive LACV infection, while LACV often kills neurons. The study also shows that neurons infected by LACV can be rescued by interferon, a powerful antiviral protein.

NIH Statement on World AIDS Day—December 1, 2019

November 25, 2019

Earlier this year, President Donald J. Trump made a bold commitment during his State of the Union Address to end the HIV epidemic in the United States. Subsequently, the U.S. Department of Health and Human Services launched an ambitious plan called Ending the HIV Epidemic: A Plan for America to reduce the incidence of HIV domestically by 75% in 5 years, and by 90% by 2030.

Eastern Equine Encephalitis Virus Poses Emergent Threat, Say NIAID Officials

November 20, 2019

Although eastern equine encephalitis (EEE), a mosquito-borne illness, has existed for centuries, 2019 has been a particularly deadly year for the disease in the United States. As of November 12, 36 confirmed cases of EEE had been reported by eight states; 13 of these cases were fatal.

NIH Researchers Estimate 17% of Food-Allergic Children Have Sesame Allergy

November 04, 2019

Investigators at the National Institutes of Health have found that sesame allergy is common among children with other food allergies, occurring in an estimated 17% of this population. In addition, the scientists have found that sesame antibody testing—whose utility has been controversial—accurately predicts whether a child with food allergy is allergic to sesame. The research was published on Oct. 28 in the journal Pediatric Allergy and Immunology.

Candidate Ebola Vaccine Still Effective when Highly Diluted, Macaque Study Finds

October 18, 2019

A single dose of a highly diluted VSV-Ebola virus (EBOV) vaccine—approximately one-millionth of what is in the vaccine being used to help control the ongoing Ebola outbreak in the Democratic Republic of the Congo (DRC)—remains fully protective against disease in experimentally infected monkeys, according to National Institutes of Health scientists. The NIH investigators completed the vaccine dosage study using cynomolgus macaques and an updated vaccine component to match the EBOV Makona strain that circulated in West Africa from 2014-16.

Drug Reverses Signs of Liver Disease in People Living with HIV

October 11, 2019

Researchers at the National Institutes of Health and their colleagues at Massachusetts General Hospital (MGH) in Boston report that the injectable hormone tesamorelin reduces liver fat and prevents liver fibrosis (scarring) in people living with HIV. The study was conducted by the National Institute of Allergy and Infectious Diseases (NIAID) and the National Cancer Institute, both parts of NIH. The findings were published online today in The Lancet HIV.

Household Bleach Inactivates Chronic Wasting Disease Prions

October 04, 2019

A 5-minute soak in a 40% solution of household bleach decontaminated stainless steel wires coated with chronic wasting disease (CWD) prions, according to a new study by National Institutes of Health scientists. The scientists used the wires to model knives and saws that hunters and meat processors use when handling deer, elk and moose – all of which are susceptible to CWD. The research was conducted at Rocky Mountain Laboratories (RML) in Hamilton, Mont. RML is a component of the NIH’s National Institute of Allergy and Infectious Diseases.

Emerging Parasitic Disease Mimics the Symptoms of Visceral Leishmaniasis in People

October 01, 2019

A new study published today online in Emerging Infectious Diseases suggests that transmission of a protozoan parasite from insects may also cause leishmaniasis-like symptoms in people. The parasite, however, does not respond to treatment with standard leishmaniasis drugs. The research was conducted by scientists at the Federal Universities of Sergipe and São Carlos, the University of São Paulo, and the Oswaldo Cruz Foundation, all in Brazil, along with investigators at the National Institute of Allergy and Infectious Diseases (NIAID), part of the U.S.

NIH Forms New Collaborative Influenza Vaccine Research Network

September 30, 2019

The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, has initiated the Collaborative Influenza Vaccine Innovation Centers (CIVICs) program, a new network of research centers that will work together in a coordinated, multidisciplinary effort to develop more durable, broadly protective and longer-lasting influenza vaccines. NIAID will provide up to approximately $51 million in total first-year funding for the program, which is designed to support the CIVICs program centers over seven years.
