RESUMEN

We assessed cumulative detection and determinants of anal high-grade squamous intraepithelial lesions (HSILs) in men who have sex with men living with human immunodeficiency virus and who underwent 3 visits over 2 years, with cytology and high-resolution anoscopy, within the ANRS-EP57-APACHES study. The cumulative HSIL detection rate was 33% (134 of 410), of which 48% HSILs were detected at baseline. HSIL detection varied considerably by center (from 13% to 51%). The strongest HSIL determinants were baseline human papillomavirus 16 (adjusted odds ratio, 8.2; 95% confidence interval, 3.6-18.9) and p16/Ki67 (4.6 [2.3-9.1]). Repeated annual cytology and high-resolution anoscopy improved HSIL detection but did not fully compensate for between-center heterogeneity.

RESUMEN

We assessed cumulative detection and determinants of anal high-grade squamous intraepithelial lesions (HSIL) in men who have sex with men living with HIV who underwent three visits over two years, with cytology and high-resolution anoscopy (HRA), within the ANRS-EP57-APACHES study. Cumulative HSIL detection was 33% (134/410), of which 48% were detected at baseline. HSIL detection varied considerably by center (13-51%). Strongest HSIL determinants were baseline HPV16 (adjusted odds ratio [aOR] 8.2; 95% confidence interval [95%CI] 3.6-18.9), and p16/Ki67 (aOR 4.6; 95%CI 2.3-9.1). Repeat annual cytology and HRA improved HSIL detection but did not fully compensate between-center heterogeneity.

RESUMEN

BACKGROUND: The screening strategy for HIV-Associated Neurocognitive Disorders (HAND) is challenging. The French Expert Report recommend the use of the Cognitive Complaints Questionnaire (QPC) and the Montreal Cognitive assessment. However, the QPC has never been studied in People Living with HIV (PLWH). This study aims to determine the degree of agreement between QPC and the presence of HAND according to Frascati criteria, established by a battery of neuropsychological tests. METHODS: Data from patients who performed both a QPC and a battery of neuropsychological tests over a six-month follow-up period were evaluated retrospectively. RESULTS: A total of 121 patients were selected, with a median age of 53.1 years old. Among participants, 92.6% had an undetectable plasma viral load, 49.6% had a nadir CD4 less than 200/mm3 and 23.1% had a CDC stage C. Median CD4 cell count was 686/mm3. Prevalence of HAND was 57%, including 28.9% of Asymptomatic Neurocognitive Impairment, 24.8% of Mild Neurocognitive Disorder and 3.3% of HIV-associated Dementia. This analyze shows no agreement between QPC and HIV-associated neurocognitive disorders (kappa = -0.007). CONCLUSIONS: The QPC is not relevant in the screening for HAND. Thus, it urges to develop a specific tool to assess cognitive complaints among PLWH.

RESUMEN

BACKGROUND: There are limited data on the comparative prevalence of neurocognitive impairment (NCI) in aging people living with human immunodeficiency virus (PLHIV) and people not living with HIV. METHODS: This was a cross-sectional study of PLHIV randomly matched by age (±4 years), gender, and education with 5 HIV-uninfected individuals from the CONSTANCES cohort. PLHIV were fluent in French and sequentially included during routine outpatient visits if aged 55-70 years, with HIV viral load <50 copies/mL, and lymphocyte T-CD4 level ≥200 cells/µL in the past 24 and 12 months, respectively. The primary outcome was NCI as defined by the Frascati criteria. Multivariate normative comparison (MNC) and -1.5 standard deviations in ≥2 neurocognitive domains were secondary outcomes of NCI. RESULTS: Two hundred PLHIV were matched with 1000 controls. Median age was 62 years, and 85% were men. In PLHIV, the median T-CD4 lymphocyte level was 650 cells/µL, and median nadir T-CD4 lymphocyte level was 176 cells/µL. NCI was found in 71 (35.5%) PLHIV and in 242 (24.2%) controls (odds ratio [OR], 1.74; 95% confidence interval [CI], 1.25, 2.41). After adjusting for confounders, HIV remained significantly associated with NCI (OR, 1.50; 95% CI, 1.04, 2.16). Adjusted results were similar with NCI defined by MNC (ORMNC, 2.95; 95% CI, 1.13, 3.50) or -1.5 SD (OR-1.5, 2.24; 95% CI, 1.39, 3.62). CONCLUSIONS: In this matched study of aging individuals, HIV was significantly associated with an increased risk of NCI after adjusting for major confounders. Results were confirmed with more stringent NCI classifications. CLINICAL TRIALS REGISTRATION: NCT02592174.

RESUMEN

Primary HIV-1 infections (PHI) with non-B subtypes are increasing in developed countries while transmission of HIV-1 harboring antiretroviral resistance-associated mutations (RAMs) remains a concern. This study assessed non-B HIV-1 subtypes and RAMs prevalence among patients with PHI in university hospitals of Marseille, Southeastern France, in 2005-2015 (11 years). HIV-1 sequences were obtained by in-house protocols from 115 patients with PHI, including 38 for the 2013-2015 period. On the basis of the phylogenetic analysis of the reverse transcriptase region, non-B subtypes were identified in 31% of these patients. They included 3 different subtypes (3A, 1C, 4F), 23 circulating recombinant forms (CRFs) (CRF02_AG, best BLAST hits being CRF 36_cpx and CRF30 in 7 and 1 cases, respectively), and 5 unclassified sequences (U). Non-B subtypes proportion increased significantly, particularly in 2011-2013 vs in 2005-2010 (P = .03). CRF02_AG viruses largely predominated in 2005-2013 whereas atypical strains more difficult to classify and undetermined recombinants emerged recently (2014-2015). The prevalence of protease, nucleos(t)ide reverse transcriptase, and first-generation nonnucleoside reverse transcriptase inhibitors-associated RAMs were 1.7% (World Health Organization [WHO] list, 2009/2.6% International AIDS Society [IAS] list, 2017), 5.2%/4.3%, and 5.2%/5.2%, respectively. Etravirine/rilpivirine-associated RAM (IAS) prevalence was 4.3%. Men who have sex with men (MSM) were more frequently infected with drug-resistant viruses than other patients (26% vs 7%; P = .011). The recent increase of these rare HIV-1 strains and the spread of drug-resistant HIV-1 among MSM in Southeastern France might be considered when implementing prevention strategies and starting therapies.

RESUMEN

BACKGROUND: Immune checkpoint inhibitors (ICIs) have been a major advance in cancer management. However, we still lack prospective real-world data regarding their usage in people with HIV infection (PWH). METHODS: The ANRS CO24 OncoVIHAC study (NCT03354936) is an ongoing prospective observational cohort study in France of PWH with cancer treated with ICI. We assessed the incidence of grade ≥3 immune-related adverse events (irAEs). All grade ≥3 irAEs were reviewed by an event review. RESULTS: Between January 17, 2018, and December 05, 2023, 150 participants were recruited from 33 sites and 140 were included in this analysis. At the data cut-off date of December 05, 2023, the median follow-up was 9.2 months (IQR: 3.9-18.3), with a total of 126.2 person-years.Median age was 59 years (IQR: 54-64) and 111 (79.3%) were men. Median time since HIV diagnosis was 25 years (12-31), the median duration on antiretroviral (ARV) was 19.5 years (7.7-25.4), and the CD4 nadir was 117/µL (51-240). ICI regimens comprised anti-programmed cell death protein-1 (PD-1) for 111 (79.3%) participants, anti-programmed death-ligand 1 for 25 (17.9%), a combination of anti-PD-1 and anti-cytotoxic T-lymphocyte associated protein 4 for 3 (2.1%), and anti-PD-1 along with anti-vascular endothelial growth factor receptor for 1 (0.7%). The most frequent cancers were lung (n=65), head/neck (n=15), melanoma (n=12), liver (n=11) and Hodgkin's lymphoma (n=9).During follow-up, a total of 34 grade ≥3 irAEs occurred in 20 participants, leading to an incidence rate of 26.9 per 100 person-years. The Kaplan-Meier estimates of the proportion of participants with at least one episode of grade ≥3 irAEs were 13.8% at 6 months, 15.0% at 12 months and 18.7% at 18 months. One treatment-related death due to myocarditis was reported (0.7%). Multivariable analysis of cumulative incidence showed that participants with time since HIV diagnosis >17 years (incidence rate ratio (IRR)=4.66, p=0.002), with CD4<200 cells/µL (IRR=4.39, p<0.0001), with positive cytomegalovirus (CMV) serology (IRR=2.76, p=0.034), with history of cancer surgery (IRR=3.44, p=0.001) had a higher risk of incidence of grade ≥3 irAEs. CONCLUSION: This study showed that the incidence of a first episode of grade ≥3 irAE was 15.0% (95% CI: 9.6% to 22.9%) at 1 year and the cumulative incidence of all severe irAE episodes was 26.9 per 100 person-years. Low CD4 count, positive CMV serology, history of cancer surgery and a longer time since HIV diagnosis were associated with the occurrence of severe irAEs.

RESUMEN

OBJECTIVES AND METHODS: : Progressive multifocal leukoencephalopathy (PML) has rarely been reported in people with HIV (PWH) with long-term HIV immune-virological control. We describe the clinical and biological characteristics of patients with confirmed PML among PWH with a CD4+ cell count more than 200 cells/µl and an undetectable HIV RNA viral load after at least 6 months of combined antiretroviral therapy (cART) at the time of PML diagnosis, in the large French multicenter Dat'AIDS cohort. RESULTS: : Among 571 diagnoses of PML reported in the Dat'AIDS cohort between 2000 and 2019, 10 cases (1.75%) occurred in PWH with a CD4+ cell count greater than 200 cells/µl and an undetectable HIV RNA viral load after at least 6 months of cART. Median CD4+ cell count at PML diagnosis was 395 cells/µl (IQR 310-477). The median duration between the last detectable HIV viral load and the PML diagnosis was 41.1 months (IQR 8.2-67.4). Only one patient treated with rituximab-based chemotherapy for a large B-cell lymphoma had an established risk factor for PML. Among the nine other patients with no apparent severe immunodeficiency, multiple factors of impaired immunity could have led to the development of PML: hepatitis C virus (HCV) co-infection (n = 6), cirrhosis (n = 4), HHV-8 co-infection (n = 3) with Kaposi's sarcoma (n = 2) in association with Castleman's disease (n = 1) and indolent IgA multiple myeloma (n = 1). CONCLUSION: : This study highlights that factors other than low CD4+ cell count and high HIV viral load may be associated with the occurrence of PML. Further studies are warranted to investigate in greater detail the immunologic characteristics of PWH with immune-virological control who develop PML.

RESUMEN

Overweight is increasingly prevalent in people living with HIV (PLWH), and is a high risk factor for metabolic disorders in this population. PLWH co-infected with hepatitis C virus (HCV) have a higher risk of metabolic disorders than their mono-infected counterparts. The putative relationship between cannabis use and body weight found in the general population has never been documented in HIV-HCV co-infected people. We tested whether cannabis use is associated with body mass index (BMI), overweight, and underweight in HCV co-infected PLWH (N = 992). Mixed-effects linear and logistic regression models were used to study the association between cannabis use and the three outcomes over time. After multivariable adjustment, cannabis use was inversely associated with BMI. Cannabis use was associated with a lower and higher risk of overweight and underweight, respectively. Cannabis use should be assessed and taken into account in the clinical management of the HIV-HCV co-infected population.

RESUMEN

BACKGROUND: We compared the prevalence of frailty among aging people living with HIV (PLHIV) with people without HIV from the ANS EP58 HAND 55-70 Study. METHODS: Cross-sectional multicentric study which consecutively included 200 PLHIV and 1000 people without HIV from the French national CONSTANCES cohort, matched on age, sex, and education level. PLHIV were aged 55-70 years, with a HIV viral load < 50 copies/mL and a lymphocyte T-CD4 level > 200 cells/µL for the last 24 and 12 months, respectively. We measured frailty (>2 items) and prefrailty (one or 2 items) using a proxy of the 5-item Fried score. Multivariate logistic regression was performed to assess the association between HIV and frailty/prefrailty, adjusting for demographic, social, behavioral, and comorbidity confounders. RESULTS: Outcome measures were available for 192 PLHIV and 822 people without HIV. The median age was 62 years, and 84.9% were men. Among PLHIV, the median CD4 cell count was 645.5 cells/µL. Prevalence of frailty/prefrailty was 5.73%/57.3% in PLHIV vs. 1.73%/52.2% in people without HIV, respectively. HIV was associated with prefrailty/frailty [odds ratio = 1.89; 95% confidence interval = 1.37 to 2.61), but after adjusting for social and behavioral factors and comorbidities, HIV was not significantly associated with prefrailty/frailty (odds ratio = 1.24; 95% confidence interval: = 0.84 to 1.81). In PLHIV only, frailty/prefrailty was associated with depressive symptomatology, kidney disease, and time since HIV infection. CONCLUSIONS: Prevalence of frailty is increased in aging PLHIV with well-controlled HIV disease, but other factors than HIV are predominant, particularly depression and comorbidities.

RESUMEN

BACKGROUND: Cancer risk is higher in people living with HIV (PLWH) compared with the general population, and cancers related to age are expected to be most prevalent. METHODS: We determined the spectrum and incidence rates of AIDS-defining cancers (ADC) and non-AIDS-defining cancers (NADC) and of lung, Hodgkin lymphoma (HL), head and neck (HNC), colon-rectum, anal, liver, breast, prostate, and urinary bladder cancers between January 2010 and December 2015 in the French Dat'AIDS cohort. Incidence rates were calculated by year and compared using the χ 2 test for linear trend. Standardized incidence ratios [SIR (95% confidence interval)] were calculated relative to the French general population. RESULTS: Among 44,642 patients, corresponding to 180,216.4 person-years (PY), 1,440 cancer cases occurred in 1,314 patients. ADC incidence was 191.4 (172.3-212.7)/105 PY and declined over time overall and in men, whereas NADC incidence was higher [548.8 (515.6-584.1)/105 PY] and did not change. In men, non-Hodgkin lymphoma was the most common cancer, but prostate cancer had the highest incidence among NADCs. Breast cancer was the most common cancer in women. SIRs were higher for cervical cancer [1.93 (1.18-3.14)], HNC in women [2.4 (1.4-4.2)], liver [overall: 3.8 (3.1-4.6); men: 3.2 (2.5-4.0); women: 12.9 (8.3-20.0)], and HL [overall: 13.8 (11.1-17.1); men: 16.2 (12.9-20.4); women: 6.2 (3.22-11.9)] but lower for lung [overall: 0.7 (0.6-0.9); men: 0.7 (0.5-0.8)], prostate [0.6 (0.5-0.7)], and breast cancers [0.6 (0.4-0.7)]. CONCLUSIONS: Spectrum of NADCs has changed, with prostate and breast cancers becoming the most common despite their lower SIR. IMPACT: These results confirm the need to maintain regular epidemiologic cancer monitoring in order to update screening guidelines.

RESUMEN

OBJECTIVE: Treatment recommendations for hepatitis C now make no distinction between HIV/HCV-coinfected and HCV-monoinfected patients. The largest challenge remained lack of effective models to eliminate HCV in people living with HIV. We report the results of a microelimination program evaluating the possibility of eradicating HCV in an HIV-outpatient clinical unit within 12 months. METHODS: This HCV-microelimination program began in February 2016 in an unit following approximately 1000 HIV-infected patients and combined screening and therapeutic components according to the French guideline. A nested cohort study evaluating the impact of HCV cure on different health outcomes was conducted through self-administered questionnaires and using generalized mixed models. RESULTS: Among 601 patients eligible for HCV serological testing, 445 were evaluated, and two HCV acute infections were diagnosed. Among the 151 patients eligible for HCV RNA quantification, 119 were evaluated, and one reinfection with HCV was diagnosed. Among the 110 patients eligible for direct-acting antiviral treatment, 51 (46.4%) initiated treatment within the 12 months program, and 35 (31.8%) after. Sustained virologic response (SVR) rate was 96.1%, and two treatments failed. At least one self-reported symptom was declared by 72.5% (n = 29) of patients. Positive impact of HCV cure was observed on various markers of physical and mental health as well as on health habits. CONCLUSION: Our program should be considered as a proof of concept, which confirmed the feasibility of a HCV-microelimination program at the scale of an HIV clinical unit. However, 12 months were not sufficient to achieve our objective despite the specific organization.

RESUMEN

Pre-exposure prophylaxis (PrEP) for the prevention of HIV infection with 300 mg daily tenofovir co-formulated with 200 mg emtricitabine is recommended as one prevention option for people who are at substantial risk of acquiring an HIV infection. We report the case of a 28-year-old man who has sex with men and who was referred to our unit for a primary HIV infection with positive p18, p24 and gp160 bands on Western blot analysis but with a low HIV plasma viral load. Although HIV misdiagnosis should always be considered in cases of atypical seroconversion pattern with a low viral burden, unsupervised PrEP should be systematically investigated.

RESUMEN

Human immunodeficiency virus type 1 (HIV-1) infection promotes a generalized activation of host responses that involves not only CD4 T cells, but also cells of the microenvironment, which are not directly infected, such as endothelial cells. The mechanisms triggering HIV-1-associated vascular alterations remain poorly understood. Extracellular vesicles (EVs), implicated in cell-to-cell communication, have been recently described as carriers of microRNAs (miRNAs). Here, we show that miR-146b-5p is upregulated in both CD4 T cells, CD4 T cell-derived EVs and circulating EVs obtained from antiretroviral therapy-naive HIV-1-infected patients. We further demonstrate that EVs from T cell line overexpressing miR-146b-5p mimics (miR-146b-EVs): 1) protect their miRNA cargo from RNase degradation, 2) transfer miR-146b-5p mimics into endothelial cells and 3) reduce endothelial inflammatory responses in vitro and in vivo in the lungs of mice through the downregulation of nuclear factor-κB-responsive molecules. These data advance our understanding on chronic inflammatory responses affecting endothelial homeostasis, in infectious and non-infectious diseases and pave the way for potential new anti-inflammatory strategies.

RESUMEN

Identifying risk factors associated with overweight and obesity in HIV-infected patients.A cross-sectional study analyzing data from patients attending an HIV outpatient unit. Overweight was defined as body mass index (BMI) ≥25 kg/m; <30 kg/m, obesity was ≥30 kg/m. Patients' characteristics contemporary to BMI assessment were collected. Multivariate logistic regression identified risk factors associated with overweight/obesity.Eight hundred sixty-two patients, median age 51 years, 21.5 years of HIV infection follow-up, 585 (68%) male, 829 (96%) receiving combined antiretroviral therapy (cART) for median 16.7 years, 768 (91%) HIV load <40 copies/mL, 618 (73%) CD4 ≥500 cells/mm; 266 (31%) HCV serology, 110 (13%) had detectable HCV-RNA. Overweight affected 191 (22%) patients and obesity 46 (5%). Overweight and obesity were associated with age, HIV follow-up duration, and HIV transmission risk group. Overweight was also associated with gender and HCV status. In patients with substance use data, overweight was associated with alcohol and nonsmoking status. Obesity was associated with nonsmoking and ex-smoker status. Overweight/obesity were not found associated with cART or immune cell counts.In HIV-infected people, aging, alcohol consumption, nonsmoking, and ex-smoker status, the absence of HCV coinfection and to have cleared HCV infection are associated with overweight and/or obesity. Clinicians should be aware of these trends and consider introducing weight management programs as part of routine HIV care.

RESUMEN

OBJECTIVE: The study aims to assess the association between bone mineral density (BMD) and frailty in a cohort of HIV-infected patients. DESIGN: A cross-sectional study in an HIV outpatient unit where nearly 1000 patients are monitored. METHODS: Study participants undergoing bone densitometry were proposed an evaluation of frailty using criteria of the Cardiovascular Health Study (CHS) and the Study of Osteoporotic Fractures (SOF). Frailty markers were weight-loss, self-reported exhaustion, physical activity, grip strength, chair stands, and slow gait. Patients' characteristics were collected from an electronic medical record. Associations of frailty with BMD and osteoporosis were tested using multivariate linear and logit regression models, respectively. RESULTS: In total, 175 HIV-infected patients, 121 (69.14%) men, were analyzed. Prevalence of frailty markers, osteopenia, and osteoporosis were comparable among sexes. Despite a younger age, spinal and femoral neck BMD were lower in women (P < 0.05). Linear regression model adjusting by age, duration of HIV follow-up, BMI, smoking status, osteoarthritis, osteoporosis treatment, and the age at menopause showed a negative association of spinal and femoral BMD with frailty according to SOF criteria in women (P < 0.05). In men, SOF-defined frailty was associated with osteoporosis (odds ratio 28.79; 95% confidence interval 2.15-386.4) in a model adjusting for age, duration of HIV follow-up, CD4 nadir, CD4 T-cell count, tobacco consumption, exposure to tenofovir (TDF) and protease inhibitors. No significant associations were found between BMD and CHS-defined frailty. CONCLUSION: Our study shows that frailty according to SOF criteria is associated with low spinal BMD values in female and osteoporosis in male HIV-infected patients.

RESUMEN

OBJECTIVE: The objective of this study is to evaluate the impact of hepatitis C virus (HCV) serostatus on the evolution of CD8 cells and CD4 : CD8 ratio in HIV-infected patients on combined antiretroviral therapy (cART) who achieve sustained undetectable viral load (HIV-pVL). DESIGN AND METHODS: A longitudinal study performed in an outpatient HIV-unit following 1495 HIV-infected patients. Data of patients on cART achieving undetectable HIV-pVL for at least 3 years were collected retrospectively from our medical e-database NADIS from January 1997 to April 2005, a period defined in order to select patients who were naive of hepatitis treatment. T-cell counts were assessed every 6 months from HIV-suppression over the study period. RESULTS: Two hundred and twenty-six HIV mono-infected (group 1) and 130 HCV-coinfected patients (group 2; genotype prevalence: 42% HCV-G1, 26% HCV-G3, 11% HCV-G4 and 21% HCV-G2) fulfilled the selection criteria. cART regimens were comparable between the groups, as were CD4 and CD8 cell counts at the first undetectable HIV-pVL. After 3 years, both groups displayed similar CD4 cell reconstitution, although CD4 percentage was higher in group 1 (30.3 ±â€Š1.1 vs. 27 ±â€Š1.1%; P < 0.001). HIV suppression led to a significant drop of median CD8 cell counts in group 1 (P = 0.027), but not in group 2, which displayed higher CD8 cell counts all through the follow-up (mean diff. = 135.71 ±â€Š26.89 cells/µl, P < 0.001). Moreover, the fraction of patients reaching CD4 : CD8 ratio ≥ 1 was lower in group 2 (14 vs. 27.7%; P < 0.05). CONCLUSION: Despite sustained HIV suppression under cART, HCV coinfection was found to hamper CD8 downregulation. Further studies will determine the impact of treatment with direct-acting antiviral agents on the CD8 pool, and the advantage of systematic HCV-targeted therapy for HIV/HCV-coinfected patients.
