The findings, published today in Nature Immunology, are an encouraging, incremental step in developing a preventive HIV vaccine.
NIH Experts Call for Accelerated Research to Address Concurrent HIV and COVID-19 Pandemics
April 8, 2021
The COVID-19 pandemic is affecting people with or at risk for HIV both indirectly, by interfering with HIV treatment and prevention services, and directly, by threatening individual health. An effective response to these dual pandemics requires unprecedented collaboration to accelerate basic and clinical research, as well as implementation science to expeditiously introduce evidence-based strategies into real-world settings. This message comes from a review article co-authored by Anthony S.
Vaginal Ring and Oral Pre-Exposure Prophylaxis Found Safe for HIV Prevention Throughout Pregnancy
March 5, 2024
The monthly dapivirine vaginal ring and daily oral pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate and emtricitabine were each found to be safe for HIV prevention among cisgender women who started using one of them in their second trimester of pregnancy, according to findings presented today at the 2024 Conference on Retroviruses and Opportunistic Infections (CROI) in Denver. Pregnant people are estimated to be three times more likely to acquire HIV through sexual intercourse than similarly aged people who are not pregnant.
Statement: Long-Acting HIV Treatment Demonstrates Efficacy in People with Challenges Taking Daily Medicine as Prescribed
February 21, 2024
Long-acting antiretroviral therapy (ART) with cabotegravir and rilpivirine was superior in suppressing HIV replication compared to daily oral ART in people who had been unable to maintain viral suppression through an oral daily regimen, according to interim data from a randomized trial. Upon review of these findings, an independent Data and Safety Monitoring Board (DSMB) recommended halting randomization and inviting all eligible study participants to take long-acting ART.

An Isolated Viral Load Test May Generate False Positive Results for People Using Long-Acting PrEP
July 23, 2024
A single laboratory-based HIV viral load test used by U.S. clinicians who provide people with long-acting, injectable cabotegravir (CAB-LA) HIV pre-exposure prophylaxis (PrEP) did not reliably detect HIV in a multi-country study. In the study, a single positive viral load test was frequently found to be a false positive result. However, a second viral load test with a new blood sample was able to distinguish true positive results from false positive results for all participants whose initial viral load test was positive.
NIH Clinical Trial of Tuberculous Meningitis Drug Regimen Begins
December 7, 2023
A trial of a new drug regimen to treat tuberculous meningitis (TBM) has started enrolling adults and adolescents in several countries where tuberculosis (TB) is prevalent. The trial will include 330 participants aged 15 years and older who have or are likely to have TBM based on signs and symptoms, including people living with and without HIV. Because pregnant women are eligible to enroll in this study with appropriate consent, a small number of pregnant women are expected to be included.

NIH-Funded Study Finds Doxycycline Reduces Sexually Transmitted Infections by Two-Thirds
April 6, 2023
The oral antibiotic doxycycline prevented the acquisition of sexually transmitted infections (STIs) when tested among study participants who took the medication within 72 hours of having condomless sex. The post-exposure approach, termed doxy-PEP, resulted in a two-thirds reduction in the incidence of syphilis, gonorrhea, and chlamydia among the study participants.
Biomedical STI Prevention Evidence Is Inadequate for Cisgender Women
December 20, 2023
Pivotal studies of some biomedical HIV and sexually transmitted infection (STI) prevention interventions have excluded cisgender women or demonstrated low efficacy among them, limiting their prevention options relative to other populations who experience high HIV and STI incidence. Findings show doxycycline postexposure prophylaxis (better known as DoxyPEP) did not prevent STI acquisition in cisgender women, despite showing promising results in gay, bisexual, and other men who have sex with men and transgender women in a previous study.
NIH Researchers Uncover New Details on Rare Immune Disease
May 3, 2023
In an 11-year study, researchers at the National Institutes of Health have further characterized idiopathic CD4 lymphocytopenia (ICL), a rare immune deficiency that leaves people vulnerable to infectious diseases, autoimmune diseases and cancers. Researchers observed that people with the most severe cases of ICL had the highest risk of acquiring or developing several of the diseases associated with this immune deficiency. This study, published in the New England Journal of Medicine, was led by Irini Sereti M.D., M.H.S. and Andrea Lisco, M.D., Ph.D.
Emergency Department Screening More Than Doubles Detection of Syphilis Cases
September 10, 2024
Providing optional syphilis tests to most people seeking care at a large emergency department led to a dramatic increase in syphilis screening and diagnosis, according to study of nearly 300,000 emergency department encounters in Chicago. Most people diagnosed had no symptoms, which suggests that symptom-based testing strategies alone could miss opportunities to diagnose and treat people with syphilis.
