https://medicalxpress.com/hiv-aids-news/ en-us Latest health news and information about HIV & AIDS HIV (human immunodeficiency virus) is a virus that attacks the body's immune system and remains a major global health challenge because of persistent viral reservoirs, despite effective treatments. Key factors include around 40 million people living with HIV, 1 million new infections each year and permanent viral DNA integration into host cells. Some HIV proviruses hide quietly in cells and escape both medicines and the immune system, creating a permanent viral reservoir that prevents patients from being cured. https://medicalxpress.com/news/2026-08-hiv-proviruses-chronic-inflammation.html Mon, 10 Aug 2026 16:40:08 EDT news705587822 Every year, more than 120,000 newborns worldwide contract HIV, creating a global health burden that requires lifelong treatment for millions of people—assuming they have access and can afford it. New research led by Oregon Health & Science University suggests another possibility: a one-time regimen of therapies given to newborns within three days of birth to permanently clear the virus. The research is published today in the journal Nature Microbiology. https://medicalxpress.com/news/2026-08-triple-dose-regimen-permanently-hiv.html Mon, 10 Aug 2026 05:00:03 EDT news705246781 A new biostatistical modeling approach has the potential to support health decisions by pinpointing where HIV is concentrated and where people living with HIV are showing signs of severe immune suppression or delayed treatment. Published in iScience, the study shows the potential of using existing health data to identify both where HIV burden is concentrated and where different forms of prevention, treatment and support may be needed. https://medicalxpress.com/news/2026-08-hiv-disease-advanced.html Wed, 05 Aug 2026 12:20:01 EDT news705148262 If you're a Black, 34-year-old South African woman living with HIV, antiretroviral (ARV) treatment options have likely been limited to tenofovir disoproxil fumarate (TDF), lamivudine (3TC) and the "gold standard," dolutegravir (DTG). Now, another once-daily, three-drug regimen has been found to be as effective as DTG in suppressing HIV viral load. https://medicalxpress.com/news/2026-08-doravirine-dolutegravir-suppress-hiv-viral.html Mon, 03 Aug 2026 12:00:04 EDT news704977021 Scientists at the UC Davis School of Medicine have identified a naturally occurring metabolite that repairs gut damage caused by HIV infection and significantly improves the effectiveness of antiretroviral therapy (ART) in a nonhuman primate model of HIV/AIDS. https://medicalxpress.com/news/2026-07-probiotic-derived-bioactive-metabolite-reverses.html Thu, 30 Jul 2026 18:00:03 EDT news704646164 An international clinical trial led by researchers including Professor Chloe Orkin of Queen Mary University of London has shown that a once-weekly oral treatment for HIV is as effective as current leading daily therapies, offering the potential for a new treatment option that could reduce the burden of lifelong daily pill-taking. https://medicalxpress.com/news/2026-07-international-weekly-hiv-pill-daily.html Thu, 30 Jul 2026 10:40:10 EDT news704625722 The odds of human papillomavirus (HPV)-related cancers are higher among people with HIV (PWH) and solid-organ transplant recipients (SOTRs), according to a study published in JAMA Network Open. https://medicalxpress.com/news/2026-07-odds-hpv-cancers-people-hiv.html Mon, 13 Jul 2026 20:40:06 EDT news703143827 Large language models (LLMs) are only as good as the data they learn from. If their training data contains social biases, the models may unintentionally repeat those biases in their responses. As their use increases with the rise of generative AI, it has become evident that they contain biases that reinforce stereotypes based on factors like ethnicity, gender or geography. This is concerning because LLM-based chatbots have become an integral part of the health care system, where health-related stigma can negatively affect one's diagnosis and care. https://medicalxpress.com/news/2026-07-medical-ai-biased-paper.html Thu, 09 Jul 2026 08:20:05 EDT news702801724 A new HIV vaccine developed by La Jolla Institute for Immunology (LJI), Scripps Research scientists and IAVI has the potential to protect humans from developing HIV infection and AIDS. This HIV vaccine is the first to generate a high number of "broadly neutralizing" virus-fighting antibodies in primates. The research is published in the journal Nature. https://medicalxpress.com/news/2026-07-hiv-vaccine-triggers-broadly-neutralizing.html Mon, 06 Jul 2026 16:30:02 EDT news702571560 The most useful thing about a new HIV prevention guide may be a question it never asks: Why do you want to know about pre-exposure prophylaxis, or PrEP? In a pilot study at three clinics, a two-page decision aid helped people choose between a daily pill, long used to prevent HIV, and a newer injectable treatment given every two months, without requiring them to disclose details of their sex lives or explain why they wanted protection. https://medicalxpress.com/news/2026-06-hiv-stigma.html Sat, 27 Jun 2026 15:00:02 EDT news701683988 In the ongoing effort to find new therapeutics for infants born infected with the human immunodeficiency virus, an international team of investigators has discovered that babies can tolerate treatment with anti-HIV antibodies. https://medicalxpress.com/news/2026-06-hiv-bay-approach-explores-broadly.html Tue, 23 Jun 2026 09:40:03 EDT news701346396 Human immunodeficiency virus 1 (HIV-1) detection in wastewater offers a novel approach to monitor the virus in communities. Baylor College of Medicine researchers and colleagues at collaborating institutions report in Nature Communications that their method, called hybrid-capture genetic sequencing, allows them to analyze viral genomes in detail and specifically identify viral signals coming from community wastewater. https://medicalxpress.com/news/2026-06-wastewater-hidden-hiv-burden-communities.html Mon, 15 Jun 2026 16:20:13 EDT news700758118 Antiretroviral drugs for HIV infection have enabled most people living with the virus to live long and healthy lives. However, a small portion of people experience detectable—and worrisome—traces of the virus that causes AIDS despite strict adherence to long-term treatment regimens and the absence of symptoms. https://medicalxpress.com/news/2026-06-defective-hiv-persistent-blood-treatment.html Mon, 08 Jun 2026 05:00:07 EDT news699868442 A class of flu drugs may reduce cognitive decline and premature aging in people living with chronic viral infection, reports a new study led by Northwestern University that began with blood samples from people with HIV and extended into preclinical drug trials. The findings point to a potential new therapy for cognitive problems in people with HIV, with broader implications for other aging-related diseases, such as dementia. The study is published in Med. https://medicalxpress.com/news/2026-06-flu-drugs-cognitive-decline.html Fri, 05 Jun 2026 11:00:03 EDT news699781862 Glucagon-like peptide-1 (GLP-1) receptor agonist medications have gained widespread attention for effectively treating obesity, lowering blood sugar and decreasing the risk of cardiovascular disease. Some researchers have proposed that these drugs may also influence the biology of aging, but direct evidence in humans has remained limited. https://medicalxpress.com/news/2026-06-popular-glp-drug-biological-aging.html Wed, 03 Jun 2026 06:44:06 EDT news699687771 For many people living with HIV, today's treatments can suppress the virus and dramatically improve health. But even when HIV is controlled, damage to the gut caused by the disease can persist, fueling chronic inflammation linked to serious health problems. A new Tulane University study published in JCI Insight helps explain why. https://medicalxpress.com/news/2026-05-broccoli-compounds-hiv-linked-gut.html Mon, 25 May 2026 14:20:01 EDT news698933282
