EU/EEA: HIV diagnoses rise for the first time in a decade

New HIV diagnoses rose by 31% in the EU/EEA in 2022, with migrants accounting for 49% of cases. Ukrainian refugees made up a significant proportion of new diagnoses, with women disproportionately affected. The increase highlights the need for tailored early testing and treatment approaches to address this growing public health threat.

Pinpointing HIV immune response

A new study reveals that CD8+ T cells control HIV infection by both cytolytic effects and non-cytolytic suppression of virus production. The research team used computer modeling and experiments with macaques to understand the immune system's mechanism in controlling HIV infections.

Syphilis transmission in US higher among transgender women and Black gay and bisexual men, study finds

A new study by Northwestern University found that syphilis rates are nearly twice as high among transgender women and Black gay and bisexual men compared to white gay men. The study suggests that preventing and treating syphilis requires outreach to key populations, particularly those from communities of color.

Use of rapid tests to diagnose tuberculosis among people with HIV in Africa has increased, but barriers to implementation remain

A study found that only 3 out of 22 African countries with high TB/HIV burden have no national policy on LF-LAM test implementation. Main barriers include lack of funding and training, despite the test being less expensive than other diagnostic tests.

Study finds users prefer daily oral PrEP pill despite new options

A new study by UConn researchers found that patients overwhelmingly prefer the traditional daily oral PrEP pill over newer forms, citing its efficacy and minimal side effects as key factors. The study highlights the importance of addressing socioeconomic disparities to ensure equitable access to these life-saving technologies.

Study identifies patient and clinician-level characteristics associated with sexual history screening administration

A mixed methods study of 53,246 patients and 56 clinicians found that gay and lesbian patients, cisgender women, and doctors' sociodemographics are linked to higher odds of documented sexual history. Conversely, older patients, long-term relationships, and non-English primary languages are associated with lower odds.

Danish researchers take another big step toward HIV cure

A large international study led by Danish researchers may have brought us closer to a cure for HIV. The study found that patients who received monoclonal antibodies before pausing their regular treatment experienced a period of virus suppression, and some even saw their immune system partially or completely suppress the virus.

“Dormant” HIV produces RNA and proteins during anti-retroviral therapy

Researchers found that a subset of HIV-infected cells produce viral RNA and proteins during anti-retroviral therapy, which may impact patients' immune responses. The study suggests that these non-functional viral pieces can stimulate an immune response, potentially leading to inflammation and negative consequences for treated individuals.

Remission from HIV-1 infection: discovery of broadly neutralizing antibodies that contribute to virus control

Researchers have identified a family of broadly neutralizing antibodies targeting the HIV-1 envelope protein, which may contribute to long-term remission from infection. These antibodies were found to induce the elimination of infected cells and impose a selective pressure on the virus, paving the way for new therapeutic approaches.

BU study: PrEP to reduce HIV incidence not available in one in three New England colleges and universities

A new study found that more than one-third of New England colleges and universities do not offer PrEP, a medication that reduces HIV incidence by over 90%. The lack of access hinders HIV prevention efforts among young gay, bisexual, and other men who have sex with men, who account for 80% of new HIV infections among youth ages 13–24.

International migrants left behind in HIV response: study

A recent study found that international migrants in Australia are at increased risk of HIV infection due to reduced access to PrEP, a highly effective prevention measure. The study identified multiple barriers, including lack of awareness, low risk perception, and provider discrimination, which hinder their ability to access PrEP.

State medical cannabis laws not associated with reduced use of opioid or nonopioid pain treatments

A study of commercially insured adults with chronic noncancer pain found that state medical cannabis laws did not lead to a reduction in the use of opioid or nonopioid pain treatments. The researchers also suggested slow implementation and reluctance among healthcare leaders may have contributed to these findings.

Africa's share of global HIV research output has increased from 5.1% to 31.3% over the last 35 years, but is still low compared to its relative burden of infections

African countries have made significant progress in increasing their share of global HIV research output, rising from 5.1% in 1986 to 31.3% between 1986 and 2020. Despite this growth, the continent still produces relatively low amounts of HIV research compared to its high burden of infections.

People who preserve ‘immune resilience’ live longer, resist infections

A multinational study identified immune resilience as a critical factor influencing life span, HIV/AIDS, flu, sepsis mortality, recurrent skin cancer, and COVID-19 mortality. Individuals with optimal levels of immune resilience were more likely to resist infections and recover from inflammatory stressors.

Novel gene-editing strategy leverages unusual genetic alteration to block HIV spread in cells

Scientists at Temple University have developed a novel gene-editing strategy that disrupts the ability of HIV-1 virus to enter host cells by targeting a rare genetic disorder. This approach may offer another target for developing next-generation CRISPR technology for HIV elimination, while avoiding adverse effects on cell mortality.

HIV status is not associated with mpox treatment outcomes in persons using tecovirimat

A cohort study of 196 people treated with tecovirimat found that HIV status did not impact treatment outcomes. Only 22% of participants experienced nonsevere adverse effects, and 4 serious adverse events occurred, with 3 being persons with HIV. The findings contradict previous uncertainty about HIV's role in mpox acquisition.
