The shifting age distribution of people with HIV using antiretroviral therapy in the United States

A United States HIV provider survey of antiretroviral therapy management in people living with HIV with co-occurring conditions

INTRODUCTION

Simplified HIV treatment guidelines favor integrase strand transfer inhibitors (INSTIs). However, non-infectious comorbidities and co-occurring conditions (i.e. pregnancy) often necessitate individualized antiretroviral therapy (ART) regimens. This study aimed to characterize United States HIV provider strategies for ART selection when faced with concomitant health conditions.

METHODS

A survey of US HIV providers was conducted using hypothetical patient cases. Standardized clinical case-vignettes were developed and providers were asked to select their preferred regimen. Eleven cases focused on cardiometabolic syndrome, renal dysfunction, weight gain, and pregnancy.

RESULTS

119 providers responded across all cases (with a median 57 responses [interquartile range 55.5-72] per case), and were primarily Infectious Diseases physicians in academic settings from across the continental United States. Bictegravir/tenofovir alafenamide/emtricitabine was most commonly prescribed for three case-scenarios of cardiometabolic disease (62.3%). Diverse regimens were recommended for a case involving weight gain, with 98.5% switching from dolutegravir plus tenofovir alafenamide/emtricitabine, most commonly to doravirine/tenofovir disoproxil fumarate/lamivudine. Dolutegravir-based regimens were selected in case-scenarios of pregnancy (77.3%), with some use of bictegravir/tenofovir alafenamide/emtricitabine (13.6%). For two case-scenarios renal disease with worsening creatinine clearance to < 30 mL/minute, many providers used lamivudine or emtricitabine in fixed-dose combination (43.3%).

CONCLUSION

This study reveals varied ART approaches for people living with HIV and non-infectious conditions, often diverging from standard regimens. While guidelines provide a framework, providers adapt treatment based on patient needs. Further research is crucial to optimize ART management in these complex situations.

Effectiveness, safety, and patient-reported outcomes of bictegravir/emtricitabine/tenofovir alafenamide in routine clinical care in Italy: 12-Month results from the BICSTaR cohort

BACKGROUND

BICSTaR is a multi-national, observational cohort evaluating the effectiveness, safety, and patient-reported outcomes (PROs) in treatment-naïve (TN) and -experienced (TE) people with HIV-1 receiving bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in routine clinical care. We present the 12-month (M12) outcomes of the Italian BICSTaR cohort.

METHODS

Participants initiating B/F/TAF in routine care were prospectively followed. Outcomes included virological and immunologic effectiveness, drug-related adverse events (DRAEs), treatment persistence, and PROs using the HIV Symptom Index (HIV-SI) and the HIV Treatment Satisfaction Questionnaires (HIVTSQ).

RESULTS

N = 201 were included (29 TN, 172 TE), 83% male, median age 38 years in TN, 48 years in TE. At baseline, 94% of TE had an HIV-1 RNA <50 cp/mL, 92% switched to B/F/TAF for simplification. Overall, 69% reported comorbidities (TN: 59%, TE: 70%). At M12, 88% (23/26) of TN and 96% (152/159) of TE had an HIV-1 RNA <50 cp/mL in the discontinuation = failure analysis (without emergence of resistance to B/F/TAF). Median CD4 count changes were +296 cells/µL (interquartile range [IQR], 118, 383) in TN, and +23 cells/µl (-137, 114) in TE. DRAEs were reported for 5% and led to discontinuation in 1%. M12 persistence on B/F/TAF was 97%. TN had a median HIV-SI bothersome symptom count decrease of -1.5 (IQR, -5.0, 0.0). Median treatment satisfaction change score was +29.0 (21, 30) in TE indicating an improvement.

CONCLUSIONS

In this real-world Italian cohort of mostly treatment-experienced people switching for simplification, B/F/TAF demonstrated high effectiveness and persistence over 12 months and confirmed the favourable safety profile shown in clinical trials.

Antiretroviral Drugs for Treatment and Prevention of HIV in Adults: 2024 Recommendations of the International Antiviral Society-USA Panel

Importance

New data and new antiretroviral drugs and formulations continue to become available for the prevention and management of HIV infection.

Objective

To provide updated recommendations for HIV treatment and clinical management and HIV prevention.

Methods

A panel of volunteer expert physician scientists were appointed to provide updated consensus recommendations for 2024. Relevant evidence in the literature since the last report was identified from PubMed and Embase searches (which initially yielded 3998 unique citations, of which 249 were considered relevant); from ongoing monitoring of the literature by the panel members; from data submitted by product manufacturers; and from studies presented at peer-reviewed scientific conferences between June 2022 and October 2024.

Findings

Antiretroviral therapy continues to be recommended for all individuals with HIV. For most people with HIV, initial regimens composed of an integrase strand transfer inhibitor (InSTI), specifically bictegravir or dolutegravir, with 2 (and in some cases 1) nucleoside or nucleotide reverse transcriptase inhibitors are recommended. Recommendations are made for those with particular clinical circumstances, such as pregnancy and active opportunistic diseases, as well as for those unable to take InSTIs. Regimens may need to be changed for virologic failure, adverse effects, convenience, or cost, among other reasons. Long-acting injectable therapy is available for those who prefer not to take daily oral medications and for people struggling with adherence to daily therapy. Recommendations are provided for laboratory monitoring, management of substance use disorders and weight changes, as well as use of statins for cardiovascular disease prevention. For HIV prevention, oral (daily or intermittent) and injectable long-acting medications are effective options for people at increased likelihood of HIV exposure. Further, new tools for maintaining health and well-being among people with HIV, such as doxycycline postexposure prophylaxis to avert sexually transmitted infection, and strategies to treat substance use disorders, are recommended. Disparities in HIV acquisition and care access are discussed and solutions proposed.

Conclusions

New approaches for treating and preventing HIV offer additional tools to help end the HIV epidemic, but achieving this goal depends on addressing disparities and inequities in access to care.

The Association of HIV Criminalization Law and Disparities in Transplant Education among People with HIV

While people with HIV (PWH) experience high rates of end-stage kidney disease (ESKD), they were historically denied kidney transplantation and prohibited from organ donation, both elements of treating ESKD. It remains unknown to what extent such HIV criminalization laws correlate with the provision of transplantation education to PWH. We conducted this study to elucidate the relationship between these structural-level policies and individual-level outcomes. State-level HIV criminalization laws were linked with the United States Renal Data System (2017-2020) to examine the association between HIV criminalization laws, HIV-status, and transplant education using logistic regression, and the association between transplant education, mortality, waitlisting, and transplantation using Cox proportional hazards regression. There were 164,223 incident ESKD patients in 2017 (PWH = 2,051). PWH had significantly higher odds of education than people without HIV in states without HIV criminalization laws (OR: 1.78, 95% confidence interval [CI]: 1.48-2.13, p-value < 0.001). Within states with HIV criminalization laws, there was no significant difference in odds of education by HIV-status (OR: 1.22, 95% CI: 0.98-1.53), suggesting that PWH residing in states with HIV criminalization laws were significantly less likely to receive transplant education than PWH residing in states without such laws (interaction OR: 0.76, CI: 0.61-0.96, p < 0.001). While many states have revised or overturned their HIV criminalization laws to permit organ donation from PWH, such laws remain in effect in others and disproportionately limit access to care for PWH. Eliminating laws limiting PWH's ability to participate in organ donation may benefit the health of PWH with ESKD residing in those states.

Individualizing Antiretroviral Therapy in the Older Patient

Owing to widespread availability of potent and tolerable antiretroviral therapy, life expectancy of people with human immunodeficiency virus (HIV) has significantly increased. Consequently, the population of people with HIV are ageing, with over 50% over the age of 50 years, and it is expected that 25% will be over the age of 65 years by 2030. People diagnosed with HIV at older age tend to have more advanced disease, and may already be experiencing comorbidities that will influence the choice of initial antiretroviral treatment. Despite the well described changes in pharmacokinetics associated with ageing, there are a paucity of pharmacokinetics studies of contemporary antiretroviral drugs to help guide treatment for HIV. Irrespective of this, integrase inhibitor-based regimens have been shown to have similar treatment outcomes in older and young adults and are the preferred regimens for initiation and switching therapy in older adults. Non-acquired immunodeficiency syndrome (AIDS) comorbidities are more common in people with HIV owing to chronic immune activation and inflammation even in the presence of virological suppression on antiretroviral treatment. Screening and risk assessment of comorbidities is crucial as the presence of geriatric syndrome, frailty or neurocognitive impairment may impact medication adherence. Simplification of complex regimens, both antiretroviral and comorbidity treatments, is recommended to improve adherence. Regular medication reviews under the guidance of an experienced HIV pharmacist are recommended to identify adverse drug-drug interactions and inappropriate prescribing of drugs with potential adverse effects, such as falls risk. Antiretroviral stewardship has been shown to improve patient outcomes and quality of life for ageing people with HIV.

Disentangling the Effects of Comorbidity and Polypharmacy on Cognitive Function and Physical Frailty in Individuals With HIV

OBJECTIVE

To estimate the extent to which comorbidity, polypharmacy, and anticholinergic/sedative burden interrelate to influence cognitive ability, perceived cognitive deficits (PCD), and physical frailty in people living with HIV.

DESIGN

Cross-sectional Structural Equation Modeling of data from 824 older people living with HIV in Canada, participating in the Positive Brain Health Now study.

METHOD

Structural Equation Modeling was used to link observed variables, including comorbidity, polypharmacy, anticholinergic, and sedative burden, to cognitive ability and 2 latent constructs-physical frailty and PCD. The model was adjusted for age, sex, education, nadir CD4, duration of HIV, and symptoms of anxiety/depression. Maximum Likelihood with Robust standard errors and bootstrapping were used to test the robustness and significance of the model's indirect effects.

RESULTS

Anticholinergic burden had a direct significant negative relationship with cognitive ability (βstd = -0.21, P < 0.05) and indirect effect on PCD (βstd = 0.16, P < 0.01) and frailty (βstd = 0.06, P < 0.01) through sedative burden. Sedative burden was directly associated with PCD (βstd = 0.18, P < 0.01) and indirectly with frailty through PCD (βstd = 0.07, P < 0.01). Comorbidity and polypharmacy exerted indirect effects on PCD and physical frailty through anticholinergic and sedative burden. The model fits the data well (CFI: 0.97, TLI: 0.94, RMSEA: 0.05, SRMR: 0.04).

CONCLUSIONS

Anticholinergic and sedative burden function as a pathway through which polypharmacy and comorbidities influence physical frailty and PCD. Reducing the use of anticholinergic and sedative medications could help prevent and manage cognitive impairment and frailty in older people living with HIV.

Challenges of HIV Management in an Aging Population

PURPOSE OF REVIEW

Potent, well tolerated and simple to administer antiretroviral therapy (ART) has resulted in significant improvement in life expectancy for people with HIV. The increased lifespan does not necessarily equate to improved healthspan with increased rates of comorbidities, frailty and geriatric syndrome experienced by older people with HIV. This review explores the challenges in prevention and management of multimorbidity and geriatric syndrome with the ultimate goal of improving health and quality of life through holistic care.

RECENT FINDINGS

Recent studies have drawn attention to the multifactorial nature of most comorbidities experienced by people with HIV. Adverse effects of contemporary ART, combined with lifestyle factors of smoking, excess alcohol and other substance use, chronic immune activation and inflammation associated with chronic HIV infection and other co-infections, all impact multimorbidity and geriatric syndromes. The complex healthcare needs of the aging population of people with HIV will require comprehensive, multidisciplinary integrated models of care.

The Association of Anemia With Survival Among People With HIV Following Antiretroviral Initiation in the NA-ACCORD 2007-2016

BACKGROUND

Anemia is an independent predictor of mortality, which may be utilized as a signal of deteriorating health. We estimated the association between anemia severity categories and mortality following the initiation of antiretroviral therapy (ART) among people with HIV (PWH) in North America.

METHODS

Within the NA-ACCORD, annual median hemoglobin measurements between January 01, 2007, and December 31, 2016, were categorized using World Health Organization criteria into mild (11.0-12.9 g/dL men, 11.0-11.9 g/dL women), moderate (8.0-10.9 g/dL men/women), and severe (<8.0 g/dL men/women) anemia. Discrete time-to-event analyses using complementary log-log link models estimated mortality hazard ratios adjusted for demographics, comorbidities, and HIV clinical markers with 95% confidence intervals for the association between anemia and mortality.

RESULTS

Among 67,228 PWH contributing a total of 320,261 annual median hemoglobin measurements, 257,293 (80%) demonstrated no anemia, 44,041 (14%) mild, 18,259 (6%) moderate, and 668 (0.2%) severe anemia during follow-up. Mortality risk was 5.6-fold higher among PWH with (vs. without) anemia. The association was greater among men (adjusted hazard ratios = 5.8 [5.4, 6.2]) versus women (adjusted hazard ratios = 4.1 [3.2, 5.4]). Mortality risk was 3.8-fold higher among PWH with mild anemia, 13.7-fold higher with moderate anemia, and 34.5-fold higher with severe anemia (vs. no anemia). Median hemoglobin levels decreased significantly in the 4 years before death, with a maximum decrease in the year before death. Macrocytic anemia was associated with an increased mortality risk and microcytic anemia was associated with a decreased mortality risk (vs. normocytic anemia).

CONCLUSIONS

Anemia among PWH who have initiated ART is an important predictive marker for mortality with macrocytic anemia having an increased association and microcytic anemia having a decreased association with mortality compared with normocytic anemia.

Pharmacokinetic evaluation of bictegravir + emtricitabine + tenofovir alafenamide in HIV treatment

INTRODUCTION

The combination of bictegravir, emtricitabine, and tenofovir alafenamide (BIC/FTC/TAF) represents a valid option of antiretroviral therapy (ART) as first line regimen both in ART-naïve and -experienced people with HIV (PWH). This review evaluates the pharmacokinetic profiles of these drugs and their clinical implications.

AREAS COVERED

This article discusses the pharmacokinetics and pharmacodynamics of BIC/FTC/TAF. It covers their efficacy, safety, tolerability, and potential drug-drug interactions. It also examines the benefits of this combination therapy, including improved adherence due to once-daily dosing and reduced toxicity compared to previous therapies. The review includes data from phase III trials and real-world studies, with a focus on treatment outcomes in diverse populations.

EXPERT OPINION

BIC/FTC/TAF's high genetic barrier to resistance and independence from boosting agents represent strengths from the pharmacokinetic perspective. The combination's once-daily, single-tablet regimen ensures consistent therapeutic drug levels and makes this regimen a viable treatment choice even for those with suboptimal adherence. With clinical trial data demonstrating efficacy and safety, as well as ease of use, BIC/FTC/TAF plays a central role in international guidelines. As the HIV treatment landscape continues to evolve, this regimen will remain a cornerstone of oral ART and may serve as a model for future therapies.

A Forecast of the HIV Clinician Workforce Need in the United States: Results of a Quantitative National Survey

ABSTRACT

There is a decreasing HIV care workforce in the United States, whereas the need for HIV care and prevention continues to increase. To better understand this issue, a quantitative, anonymous, one-time, self-administered survey was conducted. The survey was completed by 1,004 prescribing clinicians currently providing HIV-related health care. Clinicians of younger age and Black race, advanced practice registered nurses, and family medicine physicians were more likely to report continuing with the same number of patients or increasing the number of patients in their HIV practice in the next 5 years. The need for more prescribing HIV care clinicians is paramount because 17.8% reported plans to stop HIV clinical care wholly or to decrease the number of people living with HIV in their practice over the next 5 years. The most common reasons for leaving include retirement, administrative burden, and burnout.

BoneScore: A natural language processing algorithm to extract bone mineral density data from DXA scans

Objective: To develop and test an NLP algorithm that accurately detects the presence of information reported from DXA scans containing femoral neck T-scores of the patients scanned. Methods: A rule-based NLP algorithm that iteratively built a collection of regular expressions in testing data consisting of 889 snippets of text pulled from DXA reports. This was manually checked by clinical experts to determine the proportion of manually verified annotations that contained T-score information detected by this algorithm called 'BoneScore'. Testing of 30- and 50-word lengths on each side of the key term 'femoral' were pursued until achievement of adequate accuracy. A separate clinical validation regressed the extracted T-score values on five risk factors with established associations. Results: BoneScore built a set of 20 regular expressions that in concert with a width of 50 words on each side of the key term yielded an accuracy of 98% in the testing data. The extracted T-scores, when modeled with multivariable linear regression, consistently exhibited associations supported by the literature. Conclusion: BoneScore uses regular expressions to accurately extract annotations of T-score values of bone mineral density with a width of 50 words on each side of the key term. The extracted T-scores exhibit clinical face validity.

Cohort profile update: the Johns Hopkins HIV clinical cohort, 1989-2023

The Johns Hopkins HIV Clinical Cohort, established in 1989, links comprehensive, longitudinal clinical data for adults with HIV receiving care in the Johns Hopkins John G. Bartlett Specialty Practice in Baltimore, Maryland, USA, to aid in understanding HIV care and treatment outcomes. Data include demographics, laboratory results, inpatient and outpatient visit information and clinical diagnoses, and prescribed and dispensed medications abstracted from medical records. A subset of patients separately consents to self-report patient-centric outcomes on standardized instruments approximately every 6 months, and another subset separately consents to contribute plasma and peripheral blood mononuclear cells to a linked specimen repository approximately annually. The cohort has cumulatively enrolled over 8000 people, with just under 2000 on average attending ≥ 1 HIV primary care visit in any given year. The cohort reflects the HIV epidemic in Baltimore: in 2021, median age was 57, 64% of participants were male, 77% were non-Hispanic Black, and 37% acquired HIV through injection drug use. This update to the cohort profile of the Johns Hopkins HIV Clinical Cohort illustrates both how the population of people with HIV in Baltimore, Maryland, USA has changed over three decades, and we have adapted data collection procedures over three decades to ensure this long-running cohort remains responsive to patient characteristics and research gaps in the provision of care to people with HIV and substance use.

Recent and projected incidence trends and risk of anal cancer among people with HIV in North America

BACKGROUND

Anal cancer risk is elevated among people with HIV. Recent anal cancer incidence patterns among people with HIV in the United States and Canada remain unclear. It is unknown how the incidence patterns may evolve.

METHODS

Using data from the North American AIDS Cohort Collaboration on Research and Design, we investigated absolute anal cancer incidence and incidence trends nationally in the United States and Canada and in different US regions. We further estimated relative risk compared with people without HIV, relative risk among various subgroups, and projected future anal cancer burden among American people with HIV.

RESULTS

Between 2001 and 2016 in the United States, age-standardized anal cancer incidence declined 2.2% per year (95% confidence interval = ‒4.4% to ‒0.1%), particularly in the Western region (‒3.8% per year, 95% confidence interval = ‒6.5% to ‒0.9%). In Canada, incidence remained stable. Considerable geographic variation in risk was observed by US regions (eg, more than 4-fold risk in the Midwest and Southeast compared with the Northeast among men who have sex with men who have HIV). Anal cancer risk increased with a decrease in nadir CD4 cell count and was elevated among those individuals with opportunistic illnesses. Anal cancer burden among American people with HIV is expected to decrease through 2035, but more than 70% of cases will continue to occur in men who have sex with men who have HIV and in people with AIDS.

CONCLUSION

Geographic variation in anal cancer risk and trends may reflect underlying differences in screening practices and HIV epidemic. Men who have sex with men who have HIV and people with prior AIDS diagnoses will continue to bear the highest anal cancer burden, highlighting the importance of precision prevention.

Forecasting the effect of HIV-targeted interventions on the age distribution of people with HIV in Kenya

OBJECTIVES

To provide accurate forecasts of the age distribution of people with HIV (PWH) in Kenya from 2025 to 2040.

DESIGN

Development of a compartmental model of HIV in Kenya, calibrated to historical estimates of HIV epidemiology.

METHODS

We forecasted changes in population size and age distribution of new HIV infections and PWH under the status quo and under scale-up of HIV services.

RESULTS

Without scale-up, new HIV infections were forecasted to fall from 34 000 (28 000-41 000) in 2,025 to 29 000 (15 000-57 000) in 2,040; the percentage of new infections occurring among persons over 30 increased from 33% (20-50%) to 40% (24-62%). The median age of PWH increased from 39 years (38-40) in 2025 to 43 years (39-46) in 2040, and the percentage of PWH over age 50 increased from 26% (23-29%) to 34% (26-43%). Under the full intervention scenario, new infections were forecasted to fall to 6,000 (3,000-12 000) in 2,040. The percentage of new infections occurring in people over age 30 increased to 52% (34-71%) in 2,040, and there was an additional shift in the age structure of PWH [forecasted median age of 46 (43-48) and 40% (33-47%) over age 50].

CONCLUSION

PWH in Kenya are forecasted to age over the next 15 years; improvements to the HIV care continuum are expected to contribute to the growing proportion of older PWH.

Gut microbiome and cardiometabolic comorbidities in people living with HIV

BACKGROUND

Despite modern antiretroviral therapy (ART), people living with HIV (PLWH) have increased relative risk of inflammatory-driven comorbidities, including cardiovascular disease (CVD). The gut microbiome could be one of several driving factors, along with traditional risk factors and HIV-related risk factors such as coinfections, ART toxicity, and past immunodeficiency.

RESULTS

PLWH have an altered gut microbiome, even after adjustment for known confounding factors including sexual preference. The HIV-related microbiome has been associated with cardiometabolic comorbidities, and shares features with CVD-related microbiota profiles, in particular reduced capacity for short-chain fatty acid (SCFA) generation. Substantial inter-individual variation has so far been an obstacle for applying microbiota profiles for risk stratification. This review covers updated knowledge and recent advances in our understanding of the gut microbiome and comorbidities in PLWH, with specific focus on cardiometabolic comorbidities and inflammation. It covers a comprehensive overview of HIV-related and comorbidity-related dysbiosis, microbial translocation, and microbiota-derived metabolites. It also contains recent data from studies in PLWH on circulating metabolites related to comorbidities and underlying gut microbiota alterations, including circulating levels of the SCFA propionate, the histidine-analogue imidazole propionate, and the protective metabolite indole-3-propionic acid.

CONCLUSIONS

Despite recent advances, the gut microbiome and related metabolites are not yet established as biomarkers or therapeutic targets. The review gives directions for future research needed to advance the field into clinical practice, including promises and pitfalls for precision medicine. Video Abstract.

Nucleoside Reverse Transcriptase Inhibitor Exposure Is Associated with Lower Alzheimer's Disease Risk: A Retrospective Cohort Proof-of-Concept Study

Brain somatic gene recombination (SGR) and the endogenous reverse transcriptases (RTs) that produce it have been implicated in the etiology of Alzheimer's disease (AD), suggesting RT inhibitors as novel prophylactics or therapeutics. This retrospective, proof-of-concept study evaluated the incidence of AD in people with human immunodeficiency virus (HIV) with or without exposure to nucleoside RT inhibitors (NRTIs) using de-identified medical claims data. Eligible participants were aged ≥60 years, without pre-existing AD diagnoses, and pursued medical services in the United States from October 2015 to September 2016. Cohorts 1 (N = 46,218) and 2 (N = 32,923) had HIV. Cohort 1 had prescription claims for at least one NRTI within the exposure period; Cohort 2 did not. Cohort 3 (N = 150,819) had medical claims for the common cold without evidence of HIV or antiretroviral therapy. The cumulative incidence of new AD cases over the ensuing 2.75-year observation period was lowest in patients with NRTI exposure and highest in controls. Age- and sex-adjusted hazard ratios showed a significantly decreased risk for AD in Cohort 1 compared with Cohorts 2 (HR 0.88, p < 0.05) and 3 (HR 0.84, p < 0.05). Sub-grouping identified a decreased AD risk in patients with NRTI exposure but without protease inhibitor (PI) exposure. Prospective clinical trials and the development of next-generation agents targeting brain RTs are warranted.

Longitudinal trends in causes of death among adults with HIV on antiretroviral therapy in Europe and North America from 1996 to 2020: a collaboration of cohort studies

BACKGROUND

Mortality rates among people with HIV have fallen since 1996 following the widespread availability of effective antiretroviral therapy (ART). Patterns of cause-specific mortality are evolving as the population with HIV ages. We aimed to investigate longitudinal trends in cause-specific mortality among people with HIV starting ART in Europe and North America.

METHODS

In this collaborative observational cohort study, we used data from 17 European and North American HIV cohorts contributing data to the Antiretroviral Therapy Cohort Collaboration. We included data for people with HIV who started ART between 1996 and 2020 at the age of 16 years or older. Causes of death were classified into a single cause by both a clinician and an algorithm if International Classification of Diseases, Ninth Revision or Tenth Revision data were available, or independently by two clinicians. Disagreements were resolved through panel discussion. We used Poisson models to compare cause-specific mortality rates during the calendar periods 1996-99, 2000-03, 2004-07, 2008-11, 2012-15, and 2016-20, adjusted for time-updated age, CD4 count, and whether the individual was ART-naive at the start of each period.

FINDINGS

Among 189 301 people with HIV included in this study, 16 832 (8·9%) deaths were recorded during 1 519 200 person-years of follow-up. 13 180 (78·3%) deaths were classified by cause: the most common causes were AIDS (4203 deaths; 25·0%), non-AIDS non-hepatitis malignancy (2311; 13·7%), and cardiovascular or heart-related (1403; 8·3%) mortality. The proportion of deaths due to AIDS declined from 49% during 1996-99 to 16% during 2016-20. Rates of all-cause mortality per 1000 person-years decreased from 16·8 deaths (95% CI 15·4-18·4) during 1996-99 to 7·9 deaths (7·6-8·2) during 2016-20. Rates of all-cause mortality declined with time: the average adjusted mortality rate ratio per calendar period was 0·85 (95% CI 0·84-0·86). Rates of cause-specific mortality also declined: the most pronounced reduction was for AIDS-related mortality (0·81; 0·79-0·83). There were also reductions in rates of cardiovascular-related (0·83, 0·79-0·87), liver-related (0·88, 0·84-0·93), non-AIDS infection-related (0·91, 0·86-0·96), non-AIDS-non-hepatocellular carcinoma malignancy-related (0·94, 0·90-0·97), and suicide or accident-related mortality (0·89, 0·82-0·95). Mortality rates among people who acquired HIV through injecting drug use increased in women (1·07, 1·00-1·14) and decreased slightly in men (0·96, 0·93-0·99).

INTERPRETATION

Reductions of most major causes of death, particularly AIDS-related deaths among people with HIV on ART, were not seen for all subgroups. Interventions targeted at high-risk groups, substance use, and comorbidities might further increase life expectancy in people with HIV towards that in the general population.

Risk of hepatocellular carcinoma in people with HIV in the United States, 2001-2019

BACKGROUND

People with HIV have higher risk of hepatocellular carcinoma than the general population, partly because of higher prevalence of coinfection with hepatitis B virus (HBV) or hepatitis C virus (HCV).

METHODS

We calculated standardized incidence ratios for hepatocellular carcinoma in people with HIV by comparing rates from people with HIV in the HIV/AIDS Cancer Match Study, a population-based HIV and cancer registry linkage, to those in the general population. We used multivariable Poisson regression to estimate adjusted incidence rate ratios among people with HIV and linked the Texas HIV registry with medical claims data to estimate adjusted odds ratios (AORs) of HBV and HCV in hepatocellular carcinoma patients with logistic regression.

RESULTS

Compared with the general population, hepatocellular carcinoma rates in people with HIV were elevated 2.79-fold (n = 1736; 95% confidence interval [CI] = 2.66 to 2.92). Hepatocellular carcinoma rates decreased statistically significantly from 2001-2004 to 2015-2019 (P < .001). Compared with men who have sex with men, hepatocellular carcinoma risk was elevated 4.28-fold among men who injected drugs (95% CI = 3.72 to 4.93) and 1.83-fold among women who injected drugs (95% CI = 1.49 to 2.26). In Texas, 146 hepatocellular carcinoma cases among people with HIV were linked to claims data: 25% HBV positive, 59% HCV positive, and 13% coinfected with HBV and HCV. Compared with men who had sex with men, people who inject drugs had 82% decreased odds of HBV (AOR = 0.18, 95% CI = 0.05 to 0.63) and 2 times the odds of HCV (AOR = 20.4, 95% CI = 3.32 to 125.3).

CONCLUSIONS

During 2001-2019, hepatocellular carcinoma risk declined among people with HIV, though rates remain statistically significantly elevated compared with the general population, particularly among people who inject drugs. Prevention and treatment of HBV/HCV are needed to reduce hepatocellular carcinoma risk among people with HIV.

The forecasted prevalence of comorbidities and multimorbidity in people with HIV in the United States through the year 2030: A modeling study

BACKGROUND

Estimating the medical complexity of people aging with HIV can inform clinical programs and policy to meet future healthcare needs. The objective of our study was to forecast the prevalence of comorbidities and multimorbidity among people with HIV (PWH) using antiretroviral therapy (ART) in the United States (US) through 2030.

METHODS AND FINDINGS

Using the PEARL model-an agent-based simulation of PWH who have initiated ART in the US-the prevalence of anxiety, depression, stage ≥3 chronic kidney disease (CKD), dyslipidemia, diabetes, hypertension, cancer, end-stage liver disease (ESLD), myocardial infarction (MI), and multimorbidity (≥2 mental or physical comorbidities, other than HIV) were forecasted through 2030. Simulations were informed by the US CDC HIV surveillance data of new HIV diagnosis and the longitudinal North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) data on risk of comorbidities from 2009 to 2017. The simulated population represented 15 subgroups of PWH including Hispanic, non-Hispanic White (White), and non-Hispanic Black/African American (Black/AA) men who have sex with men (MSM), men and women with history of injection drug use and heterosexual men and women. Simulations were replicated for 200 runs and forecasted outcomes are presented as median values (95% uncertainty ranges are presented in the Supporting information). In 2020, PEARL forecasted a median population of 670,000 individuals receiving ART in the US, of whom 9% men and 4% women with history of injection drug use, 60% MSM, 8% heterosexual men, and 19% heterosexual women. Additionally, 44% were Black/AA, 32% White, and 23% Hispanic. Along with a gradual rise in population size of PWH receiving ART-reaching 908,000 individuals by 2030-PEARL forecasted a surge in prevalence of most comorbidities to 2030. Depression and/or anxiety was high and increased from 60% in 2020 to 64% in 2030. Hypertension decreased while dyslipidemia, diabetes, CKD, and MI increased. There was little change in prevalence of cancer and ESLD. The forecasted multimorbidity among PWH receiving ART increased from 63% in 2020 to 70% in 2030. There was heterogeneity in trends across subgroups. Among Black women with history of injection drug use in 2030 (oldest demographic subgroup with median age of 66 year), dyslipidemia, CKD, hypertension, diabetes, anxiety, and depression were most prevalent, with 92% experiencing multimorbidity. Among Black MSM in 2030 (youngest demographic subgroup with median age of 42 year), depression and CKD were highly prevalent, with 57% experiencing multimorbidity. These results are limited by the assumption that trends in new HIV diagnoses, mortality, and comorbidity risk observed in 2009 to 2017 will persist through 2030; influences occurring outside this period are not accounted for in the forecasts.

CONCLUSIONS

The PEARL forecasts suggest a continued rise in comorbidity and multimorbidity prevalence to 2030, marked by heterogeneities across race/ethnicity, gender, and HIV acquisition risk subgroups. HIV clinicians must stay current on the ever-changing comorbidities-specific guidelines to provide guideline-recommended care. HIV clinical directors should ensure linkages to subspecialty care within the clinic or by referral. HIV policy decision-makers must allocate resources and support extended clinical capacity to meet the healthcare needs of people aging with HIV.

Considerations for long-acting antiretroviral therapy in older persons with HIV

People with HIV (PWH) can now enjoy longer, healthier lives due to safe and highly effective antiretroviral therapy (ART), and improved care and prevention strategies. New drug formulations such as long-acting injectables (LAI) may overcome some limitations and issues with oral antiretroviral therapy and strengthen medication adherence. However, challenges and questions remain regarding their use in aging populations. Here, we review unique considerations for LAI-ART for the treatment of HIV in older PWH, including benefits, risks, pharmacological considerations, implementation challenges, knowledge gaps, and identify factors that may facilitate uptake of LA-ART in this population.

Impact of subgroup-specific heterogeneities and dynamic changes in mortality rates on forecasted population size, deaths, and age distribution of persons receiving antiretroviral treatment in the United States: a computer simulation study

PURPOSE

Model-based forecasts of population size, deaths, and age distribution of people with HIV (PWH) are helpful for public health and clinical services planning but are influenced by subgroup-specific heterogeneities and changes in mortality rates.

METHODS

Using an agent-based simulation of PWH in the United States, we examined the impact of distinct approaches to parametrizing mortality rates on forecasted epidemiology of PWH on antiretroviral treatment (ART). We first estimated mortality rates among (1) all PWH, (2) sex-specific, (3) sex-and-race/ethnicity-specific, and (4) sex-race/ethnicity-and-HIV-acquisition-risk-specific subgroups. We then assessed each scenario by (1) allowing unrestricted reductions in age-specific mortality rates over time and (2) restricting the mortality rates among PWH to subgroup-specific mortality thresholds from the general population.

RESULTS

Among the eight scenarios examined, those lacking subgroup-specific heterogeneities and those allowing unrestricted reductions in future mortality rates forecasted the lowest number of deaths among all PWH and 9 of the 15 subgroups through 2030. The forecasted overall number and age distribution of people with a history of injection drug use were sensitive to inclusion of subgroup-specific mortality rates.

CONCLUSIONS

Our results underscore the potential risk of underestimating future deaths by models lacking subgroup-specific heterogeneities in mortality rates, and those allowing unrestricted reductions in future mortality rates.

Differences in epigenetic age by HIV status among patients with a non-AIDS defining cancer

OBJECTIVE

People with HIV (PWH) are living longer and experiencing higher numbers of non-AIDS-defining cancers (NADC). Epigenetic aging biomarkers have been linked to cancer risk, and cancer is now a leading cause of death in PWH, but these biomarkers have not been investigated in PWH and cancer.

DESIGN

In order to compare epigenetic age by HIV status, HIV-uninfected participants were matched to PWH by reported age, tumor site, tumor sequence number, and cancer treatment status.

METHODS

DNA from blood was assayed using Illumina MethylationEPIC BeadChip, and we estimated immune cell composition and aging from three epigenetic clocks: Horvath, GrimAge, and epiTOC2. Age acceleration by clock was computed as the residual from the expected value, calculated using linear regression, for each study participant. Comparisons across HIV status used the Wilcoxon rank sum test. Hazard ratios and 95% confidence intervals for the association between age acceleration and survival in PWH were estimated with Cox regression.

RESULTS

Among 65 NADC participants with HIV and 64 without, biological age from epiTOC2 ( P  < 0.0001) and GrimAge ( P  = 0.017) was significantly higher in PWH. Biological age acceleration was significantly higher in PWH using epiTOC2 ( P  < 0.01) and GrimAge ( P  < 0.0001), with the difference in GrimAge remaining statistically significant after adjustment for immune cell composition. Among PWH, GrimAge acceleration was significantly associated with increased risk of death (hazard ratio 1.11; 95% confidence interval (CI) 1.04-1.18).

CONCLUSION

We observed a higher epigenetic age in PWH with a NADC diagnosis compared with their HIV-uninfected counterparts, as well as a significant association between this accelerated biological aging and survival for patients diagnosed with a NADC.

Lung Cancer Screening in People With HIV: A Mixed-Methods Study of Patient and Provider Perspectives

INTRODUCTION

People with HIV are at higher risk of lung cancer; however, there is limited research on attitudes, barriers, and facilitators to lung cancer screening in people with HIV. The objective of this study was to understand the perspectives on lung cancer screening among people with HIV and their providers.

METHODS

Surveys of people with HIV and HIV-care providers were complemented by qualitative focus groups and interviews designed to understand the determinants of lung cancer screening in people with HIV. Participants were recruited through an academic HIV clinic in Seattle, WA. Qualitative guides were developed by integrating the Consolidated Framework for Implementation Research and the Tailored Implementation of Chronic Diseases checklist. Themes that emerged from thematic analyses of qualitative data were compared with surveys in joint displays. All study components were conducted between 2021 and 2022.

RESULTS

Sixty-four people with HIV completed surveys, and 43 participated in focus groups. Eleven providers completed surveys, and 10 were interviewed for the study. Themes from joint displays show overall enthusiasm for lung cancer screening among people with HIV and their providers, particularly with a tailored and evidence-based approach. Facilitators in this population may include longstanding engagement with providers and health systems and an emphasis on survivorship through preventive healthcare interventions. People with HIV may also face barriers acknowledged by providers, including a high level of medical comorbidities and competing issues such as substance abuse, mental health concerns, and economic instability.

CONCLUSIONS

This study reveals that people with HIV and their providers have overall enthusiasm toward screening. However, tailored interventions may be needed to overcome specific barriers, including complex decision making in the setting of medical comorbidity and patient competing issues.

Human Papillomavirus-Associated Anal Cancer Incidence and Burden Among US Men, According to Sexual Orientation, Human Immunodeficiency Virus Status, and Age

BACKGROUND

Men who have sex with men (MSM) without HIV are known to be at elevated relative risk for Human papillomavirus (HPV)-associated anal cancer in comparison to men who have sex with women (MSW), but are poorly characterized in terms of anal cancer incidence due to absence of reporting of sexual behavior/identity at a population-level.

METHODS

By combining age-specific statistics from multiple data sources (anal cancer incidence among all males; anal cancer incidence among MSM and MSW with HIV; population size of men with HIV by sexual orientation), we developed a mathematical model to estimate anal cancer incidence, annual number of cases, and proportion by (a) sexual orientation (MSM versus MSW), (b) HIV status, and (c) age (<30, 30-44, 45-59, and ≥60 years).

RESULTS

Anal cancer incidence (per 100 000) among MSM without HIV was 1.4 (95% uncertainty interval [UI], 0.6 to 2.3), 17.6 (95% UI = 13.8-23.5), and 33.9 (95% UI = 28.3-42.3), at ages 30-44, 45-59 and ≥60 years, respectively. 19.1% of all male anal cancer occurred in MSM without HIV, increasing from 4% of anal cancer diagnosed at 30-44 years to 24% at ≥60 years; 54.3% occurred in MSW without HIV (increasing from 13% at age 30-44 to 67% at >60 years), and the remaining 26.6% in men (MSM and MSW combined) with HIV (decreasing from 83% at age 30-44 to 9% at >60 years).

CONCLUSIONS

These findings should inform anal cancer prevention recommendations in male risk groups, including, for the first time, for the important group of MSM without HIV.

The Impact of COVID-19 on HIV Care in Rio de Janeiro, Brazil 2019-2021: Disparities by Age and Gender

We evaluated COVID-19's impact on HIV care indicators among INI/FIOCRUZ's HIV Clinical Cohort in Rio de Janeiro, Brazil: (1) Adequate care visits: two visits ≥ 90 days apart; (2) Adequate viral load monitoring: ≥ 2 viral load results ≥ 90 days apart; (3) Consistent viral suppression: all viral loads < 40 copies/mL; and (4) ART medication possession ratio (MPR) ≥ 95%. Chi-square tests compared the fraction of participants meeting each indicator per period: pre-pandemic (3/1/2019-2/29/2020) and post-pandemic (3/1/2020-2/28/2021). Logistic regression models were used to assess disparities in adequate care visits. Among 906 participants, care visits and viral load monitoring decreased pre-pandemic to post-pandemic: 77.0-55.1% and 36.6-11.6% (both p < 0.001), respectively. The optimal MPR rate improved from 25.5 to 40.0% (p < 0.001). Post-pandemic period (aOR 0.33, CI 0.28-0.40), transgender women (aOR 0.34, CI 0.22-0.53), and those aged 18-24 years (aOR 0.67, CI 0.45-0.97) had lower odds of adequate care visits. COVID-19 disrupted care access disproportionately for transgender women and younger participants.

Global burden of HPV-attributable squamous cell carcinoma of the anus in 2020, according to sex and HIV status: A worldwide analysis

Squamous cell carcinoma of the anus (SCCA) is caused by HPV, and is elevated in persons living with HIV (PLWHIV). We aimed to estimate sex- and HIV-stratified SCCA burden at a country, regional and global level. Using anal cancer incidence estimates from 185 countries available through GLOBOCAN 2020, and region/country-specific proportions of SCCA vs non-SCCA from the Cancer Incidence in Five Continents (CI5) Volume XI database, we estimated country- and sex-specific SCCA incidence. Proportions of SCCA diagnosed in PLWHIV, and attributable to HIV, were calculated using estimates of HIV prevalence (UNAIDS 2019) and relative risk applied to SCCA incidence. Of 30 416 SCCA estimated globally in 2020, two-thirds occurred in women (19 792) and one-third among men (10 624). Fifty-three percent of male SCCA and 65% of female SCCA occurred in countries with a very high Human Development Index (HDI). Twenty-one percent of the global male SCCA burden occurred in PLWHIV (n = 2203), largely concentrated in North America, Europe and Africa. While, only 3% of global female SCCA burden (n = 561) occurred in PLWHIV, mainly in Africa. The global age-standardized incidence rate of HIV-negative SCCA was higher in women (0.55 cases per 100 000) than men (0.28), whereas HIV-positive SCCA was higher in men (0.07) than women (0.02). HIV prevalence reached >40% in 22 countries for male SCCA and in 10 countries for female SCCA, mostly in Africa. Understanding global SCCA burden by HIV status can inform SCCA prevention programs (through HPV vaccination, screening and HIV control) and help raise awareness to combat the disease.

A new era of HIV care for age-associated multimorbidity

PURPOSE OF REVIEW

The management of people with HIV has shifted focus from acute AIDS-defining illness towards improving detection of chronic disease and reducing impact of multimorbidity. In this review, we explore this shifting paradigm of HIV care and the evidence for alternative models proposed to provide integrated holistic services for people with HIV (PWH) with multimorbidity.

RECENT FINDINGS

Despite 25 years of the antiretroviral treatment (ART) era an increased incidence of noncommunicable disease (NCD) and multimorbidity in PWH persists. As the world moves closer to universal ART coverage this phenomenon is now reported in low- and middle-income settings. Multimorbidity affects PWH disproportionately compared to the general population and results in reduced health related quality of life (HRQoL), greater hospitalization and higher mortality. There is evidence that NCD care provision and outcomes may be inferior for PWH than their HIV negative counterparts. Various models of integrated multimorbidity care have developed and are grouped into four categories; HIV specialist clinics incorporating NCD care, primary care services incorporating HIV care, community NCD clinics offering integrated HIV care, and multidisciplinary care integrated with HIV in secondary care. Evidence is limited as to the best way to provide multimorbidity care for PWH.

SUMMARY

A new era of HIV care for an ageing population with multimorbidity brings challenges for health providers who need to develop holistic patient focused services which span a range of coexisting conditions.

Effects of frailty, geriatric syndromes, and comorbidity on mortality and quality of life in older adults with HIV

BACKGROUND

To understand the effects of frailty, geriatric syndromes, and comorbidity on quality of life and mortality in older adults with HIV (OAWH).

METHODS

Cross-sectional study of the FUNCFRAIL multicenter cohort. The setting was outpatient HIV-Clinic. OAWH, 50 year or over were included. We recorded sociodemographic data, HIV infection-related data, comorbidity, frailty, geriatric syndromes (depression, cognitive impairment, falls and malnutrition), quality of life (QOL) and the estimated risk of all-cause 5-year mortality by VACS Index. Association of frailty with geriatric syndromes and comorbidity was evaluated using the Cochran-Mantel-Haenszel test.

RESULTS

Seven hundred ninety six patients were included. 24.7% were women, mean age was 58.2 (6.3). 14.7% were 65 or over. 517 (65%) patients had ≥3 comorbidities, ≥ 1 geriatric syndrome and/or frailty. There were significant differences in the estimated risk of mortality [(frailty 10.8%) vs. (≥ 3 comorbidities 8.2%) vs. (≥ 1 geriatric syndrome 8.2%) vs. (nothing 6.2%); p = 0.01] and in the prevalence of fair or poor QOL [(frailty 71.7%) vs. (≥ 3 comorbidities 52%) vs. (≥ 1 geriatric syndrome 58.4%) vs. (nothing 51%); p = 0.01]. Cognitive impairment was significantly associated to mortality (8.7% vs. 6.2%; p = 0.02) and depression to poor QOL [76.5% vs. 50%; p = 0.01].

CONCLUSIONS

Frailty, geriatric syndromes, and comorbidity had negative effects on mortality and QOL, but frailty had the greatest negative effect out of the three factors. Our results should be a wake-up call to standardize the screening for frailty and geriatric syndromes in OAWH in the clinical practice.

Antiretroviral Drugs for Treatment and Prevention of HIV Infection in Adults: 2022 Recommendations of the International Antiviral Society-USA Panel

Importance

Recent advances in treatment and prevention of HIV warrant updated recommendations to guide optimal practice.

Objective

Based on a critical evaluation of new data, to provide clinicians with recommendations on use of antiretroviral drugs for the treatment and prevention of HIV, laboratory monitoring, care of people aging with HIV, substance use disorder and HIV, and new challenges in people with HIV, including COVID-19 and monkeypox virus infection.

Evidence Review

A panel of volunteer expert physician scientists were appointed to update the 2020 consensus recommendations. Relevant evidence in the literature (PubMed and Embase searches, which initially yielded 7891 unique citations, of which 834 were considered relevant) and studies presented at peer-reviewed scientific conferences between January 2020 and October 2022 were considered.

Findings

Initiation of antiretroviral therapy (ART) is recommended as soon as possible after diagnosis of HIV. Barriers to care should be addressed, including ensuring access to ART and adherence support. Integrase strand transfer inhibitor-containing regimens remain the mainstay of initial therapy. For people who have achieved viral suppression with a daily oral regimen, long-acting injectable therapy with cabotegravir plus rilpivirine given as infrequently as every 2 months is now an option. Weight gain and metabolic complications have been linked to certain antiretroviral medications; novel strategies to ameliorate these complications are needed. Management of comorbidities throughout the life span is increasingly important, because people with HIV are living longer and confronting the health challenges of aging. In addition, management of substance use disorder in people with HIV requires an evidence-based, integrated approach. Options for preexposure prophylaxis include oral medications (tenofovir disoproxil fumarate or tenofovir alafenamide plus emtricitabine) and, for the first time, a long-acting injectable agent, cabotegravir. Recent global health emergencies, like the SARS-CoV-2 pandemic and monkeypox virus outbreak, continue to have a major effect on people with HIV and the delivery of services. To address these and other challenges, an equity-based approach is essential.

Conclusions and Relevance

Advances in treatment and prevention of HIV continue to improve outcomes, but challenges and opportunities remain.

Two-drug regimens for HIV treatment

Combination therapy with three antiretroviral agents has been integral to successful HIV-1 treatment since 1996. Although the efficacy, adverse effects, and toxicities of contemporary three-drug regimens have improved, even the newest therapies have potential adverse effects. The use of two-drug regimens is one way to reduce lifetime exposure to antiretroviral drugs while maintaining the benefits of viral suppression. Multiple large, randomised trials have shown the virological non-inferiority of certain two-drug regimens versus three-drug comparators, including adverse effect differences that reflect known profiles of the antiretroviral drugs in the respective regimens. Two-drug combinations are now recommended in treatment guidelines and include the first long-acting antiretroviral regimen for the treatment of HIV-1. Recommended two-drug regimens differ in their risks for, and factors associated with, virological failure and emergent resistance. The tolerability, safety, metabolic profiles, and drug interactions of two-drug regimens also vary by the constituent drugs. No current two-drug regimen is recommended for people with chronic hepatitis B virus as none include tenofovir. Two-drug regimens have increased options for individualised care.

Projection of age of individuals living with HIV and time since ART initiation in 2030: estimates for France

Introduction

Thanks to antiretroviral treatment (ART), people living with HIV (PLHIV) are living longer and ageing. However, ageing involves increased risks of co‐morbidities, which also depend on when PLHIV individuals started ART. To tackle the HIV age‐related upcoming challenges, knowledge of the current and future age structure of the HIV population is needed. Here, we forecast the demographic profile of the adult population living with diagnosed HIV (aPLdHIV) in France until 2030, accounting for the impact of the ART initiation period on mortality.

Methods

We used national data from the French Hospital Database on HIV (ANRS CO4‐FHDH) and a sample of the National Health Data System to, first, characterize the aPLdHIV in 2018 and estimate their mortality rates according to age, sex and ART initiation period. Second, we used national HIV surveillance data to define three scenarios for the numbers of newly diagnosed HIV cases over 2019–2030: 30% decrease in HIV cases (S1), status quo situation (S2) and epidemic elimination (S3). We then combined these data using a matrix model, to project the age structure of aPLdHIV and time since ART initiation.

Results

In 2018, there was an estimated 161,125 aPLdHIV (33% women), of which 55% were aged 50 or older (50+), 22% aged 60+ and 8% aged 70+. In 2030, the aPLdHIV would grow to 195,246 for S1, 207,972 for S2 and 167,221 for S3. Whatever the scenario, in 2030, the estimated median time since ART initiation would increase and age distribution would shift towards older ages: with 65–72% aPLdHIV aged 50+, 42–48% 60+ and 17–19% 70+. This corresponds to ∼83,400 aPLdHIV (28% women) aged 60+, among which ∼69% started ART more than 20 years ago (i.e. before 2010) and ∼39% ≥30 years ago (i.e. before 2000), and to ∼33,100 aPLdHIV (27% women) aged 70+, among which ∼72% started ART ≥20 years ago and ∼43% ≥30 years ago.

Conclusions

By 2030, in France, close to 20% of the aPLdHIV will be aged 70+, of which >40% would have started ART more than 30 years ago. These estimates are essential to adapt co‐morbidities screening and anticipate resource provision in the aged care sector.

Complement component 3 and complement factor H protein levels are altered in brain tissues from people with human immunodeficiency virus: A pilot study

People with HIV (PWH) continue to suffer from dysfunction of the central nervous system, as evidenced by HIV-associated neurocognitive disorder (HAND), despite antiretroviral therapy and suppressed viral loads. As PWH live longer they may also be at risk of age-related neurodegenerative diseases such Alzheimer’s disease (AD) and its precursor, amnestic mild cognitive impairment (aMCI). The complement system is associated with deposition of AD-related proteins such as beta amyloid (Aβ), neuroinflammation, and neurological dysfunction in PWH. Complement component 3 (C3) is a key protagonist in the complement cascade and complement factor H (CFH) is an antagonist of C3 activity. We investigated the relationship between C3 and CFH levels in the brain and Aβ plaques and neurological dysfunction in 22 PWH. We analyzed by immunoblot C3 and CFH protein levels in frontal cortex (FC) and cerebellum (CB) brain specimens from PWH previously characterized for Aβ plaque deposition. C3 and CFH protein levels were then correlated with specific cognitive domains. C3 protein levels in the FC were significantly increased in brains with Aβ plaques and in brains with HAND compared to controls. In the CB, C3 levels trended higher in brains with Aβ plaques. Overall C3 protein levels were significantly higher in the FC compared to the CB, but the opposite was true for CFH, having significantly higher levels of CFH protein in the CB compared to the FC. However, only CFH in the FC showed significant correlations with specific domains, executive function and motor performance. These findings corroborate previous results showing that complement system proteins are associated with HAND and AD neuropathogenesis.

Hepatocellular carcinoma in Hepatitis B and Human Immunodeficiency Virus coinfection in Africa: a focus on surveillance

Human immunodeficiency virus (HIV) and hepatitis-B virus (HBV) infections are weighty public health challenges, especially in the African continent. The direct carcinogenic effect of HBV means that it remains a potent cause of early-onset hepatocellular carcinoma (HCC) in Sub-Saharan Africa (SSA), where it causes significant morbidity and mortality. The presence of HIV infection in HBV-infected patients poses a complicating factor, as coinfection has been shown to hasten the progression of liver disease to cirrhosis and HCC, and often resulting in early-age hepatocarcinogenesis with consequent late diagnosis and lower survival. In this review, we discuss this unique conundrum, the epidemiology of HIV-HBV coinfection in SSA, its effect on liver disease and development of HCC, as well as practices and barriers to HCC surveillance in this distinct population. We propose a way forward to curb this considerable health burden focusing on reduction of disease stigma, the need for easy-to-measure biomarkers, and implementation of large prospective studies in this population.
