Comorbid conditions have a major impact on the health, quality of life, and survival of people with HIV, particularly as this population ages. The 2022 Conference on Retroviruses and Opportunistic Infections (CROI) featured excellent science related to specific comorbidities, such as cardiovascular disease, type 2 diabetes, cancer, and frailty. The role of systemic inflammation in the pathogenesis of cardiovascular disease was an important theme, with strong evidence regarding the impact of microbial translocation...

The 2022 Conference on Retroviruses and Opportunistic Infections provided a rich source of new data and comprehensive reviews on antiviral therapy. For COVID-19, intramuscular sotrovimab was noninferior to intravenous sotrovimab, serostatus did not predict the efficacy of sotrovimab, and molnupiravir appeared safe and modestly effective in decreasing hospitalization rates. Trials from low- and middle-income countries provided data to support transitioning those on first-line therapy with or without virologic suppression and those virologically suppressed on second-line therapy to dolutegravir-based regimens...

Depressive disorders are the most common psychiatric disorders among people with HIV. Depressive disorders cause great suffering and disability and, among people with HIV, are associated with numerous negative HIV outcomes, including nonadherence to antiretroviral medication and increased morbidity and mortality. This article is focused on the detection, differential diagnosis, and management of depressive disorders among adults in HIV primary care settings in the United States. Because of the siloed nature of HIV primary health care and behavioral health care in the United States, this paper is geared toward clinicians who are not behavioral health specialists and who are working in HIV care settings that have limited access to behavioral health services and still seek to treat depressive disorders...

At the 2022 Conference on Retroviruses and Opportunistic Infections, several speakers discussed disparities in HIV and COVID-19 infections and outcomes. Although the lifetime risk of HIV infection in the United States is higher overall in males than females, Black females have higher risk than White males. In 12 countries in sub-Saharan Africa, women aged 15 to 34 years accounted for more than half of all infections. Because knowledge of HIV serostatus is important for treatment and for prevention, several novel strategies were evaluated in the distribution of HIV self-test kits to undertested populations in the United States and sub-Saharan Africa...

The Conference on Retroviruses and Opportunistic Infections (CROI) 2022, which was held as a virtual conference, continues to serve as the preeminent forum that features research advances in HIV-1 and its associated coinfections. The conference has extended its area of coverage to include research advances in SARS- CoV-2. As pointed out in the presentation from Hatziioannou in the New Investigators workshop, there has been an explosion in research activity on SARS-CoV-2 that has eclipsed that for HIV-1. In the past 12 months, there were approximately 6600 publications on HIV-1 and approximately 64,000 on SARS-CoV-2...

The 2022 edition of the IAS-USA drug resistance mutations list updates the Figure last published in September 2019. The mutations listed are those that have been identified by specific criteria for evidence and drugs described. The Figure is designed to assist practitioners to identify key mutations associated with resistance to antiretroviral drugs, and therefore, in making clinical decisions regarding antiretroviral therapy.

Early treatment of anal high-grade squamous intraepithelial lesions compared with active monitoring reduced the risk of anal cancer by 57% in persons with HIV in a landmark randomized trial of 4446 participants. In a multi- country randomized trial, an entirely oral combination regimen consisting of bedaquiline, pretomanid, linezolid, and moxifloxacin for 24 weeks outperformed the World Health Organization-recommended 36- to 96-week standard of care regimen for multidrug-resistant tuberculosis (TB), ushering in a new era of shorter multidrug-resistant TB treatment...

The 2022 Conference on Retroviruses and Opportunistic Infections featured new and important findings about the neurologic complications of HIV-1, COVID-19, and other infections. Long-term analyses identified that cognitive decline over time, phenotypic aging, and stroke are associated with various comorbidities in people with HIV. Neuroimaging studies showed greater neuroinflammation, white matter damage, demyelination, and overall brain aging in people with chronic HIV infection. Childhood trauma and exposure to environmental pollutants contribute to these neuroimaging findings...

Tuberculosis (TB) remains the leading cause of death among people with HIV, and annual risk of progression from latent TB infection to active disease in this population is 10%. Diagnostic tests for latent and active TB remain suboptimal for people with HIV who have a CD4+ count below 200 cells/μL, and there is an urgent need for assays that predict progression from latent to active disease, monitor treatment response, and test for cure after latent and active TB treatment. Traditional treatment duration for latent infection and active TB disease has been onerous for patients; however, shorter-course regimens are increasingly available across the spectrum of TB, including for drug-resistant TB...

Because individuals with HIV are living longer, comorbidities are moving to the forefront of HIV patient care. People with HIV have a higher risk for HIV-related and non-HIV-related cancers than the general population, making cancer screening vital for this population. Immunizations are another important element of primary care for older adults with HIV, including a COVID-19 vaccine, about which data continue to evolve. This article summarizes a presentation by Steven C. Johnson, MD, at the International Antiviral Society-USA (IAS-USA) virtual HIV course Aging and HIV: Issues, Screening, and Management in Individuals with HIV as They Age in June 2021...

Individuals with HIV have elevated risks for cardiovascular diseases (CVDs) ranging from myocardial infarction to heart failure. Our understanding of this heightened HIV-associated cardiovascular risk has evolved over the past 2 decades. In the early era of antiretroviral therapy (ART), concern existed that ART was the primary driver of cardiovascular risk. However, it has become increasingly apparent that HIV-related viremia, immune dysregulation, and inflammation are primary drivers of HIV-associated cardiovascular risk, along with traditional cardiovascular risk factors such as tobacco smoking...

Despite major advances in the HIV prevention toolbox in the past decade, there remain substantial social, economic, and structural barriers to access to preexposure prophylaxis (PrEP) that prevent a universal, population-level reduction in HIV incidence. Daily oral tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) has been the flagship PrEP regimen, and data support a pericoital/on-demand "2-1-1" dosing schedule for men who have sex with men. Daily oral PrEP with tenofovir alafenamide combined with emtricitabine (TAF/FTC) was approved by the US Food and Drug Administration (FDA) in 2019 for all routes of exposure other than vaginal exposures...

Although there is extensive literature around the biologic correlations of neurocognitive function in HIV/AIDS, less is known about the impact in everyday living. We conducted a systematic review of the association of neurocognitive impairment with everyday life functions in people with HIV on antiretroviral therapy. We specifically focused on attention, executive function, processing speed, and the central executive component of the working memory. We considered 3 domains of everyday functions: (1) autonomy, (2) decision making and adherence to treatment, and (3) quality of life and psychologic wellbeing...

At the 2021 Conference on Retroviruses and Opportunistic Infections, there was a focus on progress toward hepatitis C virus (HCV) microelimination in geographic regions and targeted populations. HCV elimination is facilitated by well-tolerated, highly effective HCV treatment that requires essentially no on-treatment monitoring in most patients, as highlighted by the MINMON (Minimal Monitoring Study or A5360) study, and that should be increasingly available to children with new data supporting feasible treatment in younger patients...

The 2021 Conference on Retroviruses and Opportunistic Infections included advances in therapy for HIV as well as for SARS-CoV-2. Data presented on COVID-19 therapies included trials showcasing the use of monoclonal antibodies for prevention and treatment of COVID-19. Promising new data were presented on lenacapavir, an investigational HIV capsid inhibitor given as a subcutaneous injection every 6 months. Although encouraging data from settings across the globe reported achievement of 90-90-90 HIV care cascade targets, disparities exist in care engagement and viral suppression, particularly for people of color and young people with HIV...

The Conference on Retroviruses and Opportunistic Infections (CROI) serves as one of the most highly visible platforms upon which researchers gather to share the most recent findings on HIV/AIDS and, recently, on SARS-CoV-2 research. Research presentations on the novel coronavirus SARS-CoV-2 have become an increasing fixture at the conference since it was first covered at last year's conference. Although CROI 2021 was virtual, the organizers coordinated a seamless platform for presentations and poster sessions that effectively engaged the audience...

Tuberculosis (TB) remains a main driver of morbidity and mortality among people with HIV along with other opportunistic infections. This review summarizes key highlights related to TB, and other opportunistic infections in HIV as well as studies from the virtual 2021 Conference on Retroviruses and Oppoprtunitstic Infections evaluating outcomes among HIV-COVID-19 coinfected patients.

The 2021 Conference on Retroviruses and Opportunistic Infections (CROI) featured a timely review of the neurologic complications of COVID-19 as well as new research findings on mechanisms by which SARS-CoV-2 may affect the brain. CROI included new and important findings about the neurologic complications of HIV-1, human polyomavirus 2 (also known as JC Virus), and cryptococcus. New long-term analyses of cognition in people with HIV-1 identified that cognitive decline over time is associated with multimorbidity, particularly diabetes, chronic lung disease, and vascular disease risk conditions...

Comorbid conditions have a major impact on the health, quality of life, and survival in people with HIV, particularly as they age. The 2021 Conference on Retroviruses and Opportunistic Infections featured excellent science related to specific comorbidities as well as multimorbidity. A number of presentations related to comorbidities in women with HIV reflected a new wave of research aimed at understanding how the epidemiology and pathogenesis of comorbidities may differ by sex. Weight gain related to antiretroviral therapy was also a major theme of the comorbidity abstracts presented at the meeting...
