Persistence of monocyte activation under treatment in people followed since acute HIV-1 infection relative to participants at high or low risk of HIV infection. EBioMedicine 2020; 62:103129. [PMID: 33248370 PMCID: PMC7704414 DOI: 10.1016/j.ebiom.2020.103129] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2020] [Revised: 11/04/2020] [Accepted: 11/05/2020] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND Interpretation of the increase in certain inflammatory markers in virally suppressed HIV-infected individuals must rely on an appropriate uninfected control group well characterized for non-HIV-related factors that contribute to chronic inflammation, e.g. smoking, alcohol consumption, or being overweight. We compared the inflammatory profiles of HIV-infected participants under long-term antiretroviral therapy (ART) with those of two HIV-uninfected groups with contrasting health behaviours. METHODS We studied 150 HIV-infected participants (42 women, 108 men) under long-term ART (median, 6 years) followed in the ANRS PRIMO cohort since acute/early HIV-1 infection (AHI) diagnosis. Sex and age-matched controls were sampled from i) the ANRS IPERGAY pre-exposure prophylaxis trial among men at high risk for HIV infection and with high frequencies of non-HIV factors of inflammation ii) the ANRS COHVAC cohort of volunteers in vaccine trials with a low-risk profile for HIV infection. We measured the plasma levels of ten inflammatory markers. FINDINGS After adjusting for smoking, alcohol use and body mass index, both HIV-infected men and women had higher levels of sCD14, sCD163, sTNFRII and I-FABP than their high-risk IPERGAY and low-risk COHVAC counterparts. Hierarchical clustering showed a subset of 15 PRIMO participants to have an inflammatory profile similar to that of most HIV-negative participants. These participants already had favourable markers at AHI diagnosis. INTERPRETATION Long-term ART, even when initiated at a low level of immunodeficiency, fails to normalize monocyte/macrophage activation and gut epithelial dysfunction. Persistent inflammation under treatment may be related to an increased inflammatory profile since AHI. FUNDING ANRS and Paris-Saclay University.

Long-term Therapeutic Impact of the Timing of Antiretroviral Therapy in Patients Diagnosed With Primary Human Immunodeficiency Virus Type 1 Infection. Clin Infect Dis 2019; 66:1519-1527. [PMID: 29211834 DOI: 10.1093/cid/cix1068] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2017] [Accepted: 11/30/2017] [Indexed: 12/20/2022] Open
Abstract
Background We aimed to determine the consequences of delayed human immunodeficiency virus type 1 (HIV-1) infection diagnosis by comparing long-term outcomes depending on the time of combination antiretroviral therapy (cART) initiation in patients diagnosed during primary HIV infection (PHI). Methods We selected patients from the French National Agency for Research on AIDS and Viral Hepatitis (ANRS) PRIMO cohort, treated for ≥36 months, with sustained HIV RNA <50 copies/mL: 77 treated within 1 month following PHI diagnosis (immediate ART) and 73 treated >12 months after infection (deferred ART). We measured inflammatory biomarkers from PHI through the last visit on cART, and CD4+ and CD8+ T-cell activation and plasma ultrasensitive HIV RNA at the last visit. Inflammation/activation levels were compared with those of uninfected controls. We modeled CD4+ count, CD4:CD8 ratio, and HIV DNA dynamics on cART. Results The decrease of HIV DNA levels was more marked in the immediate than deferred ART group, leading to a sustained mean difference of -0.6 log10 copies/106 peripheral blood mononuclear cells. Immediate ART led to improved CD4+ T-cell counts and CD4:CD8 ratios over the first 4 years of cART. At the last visit (median, 82 months), there was no difference between groups in CD4+ counts, CD4:CD8 ratio, ultrasensitive HIV RNA, or inflammation/activation marker levels. Long-term suppressive cART failed to normalize inflammation levels, which were not associated with immunovirological markers. Conclusions Antiretroviral therapy initiated during PHI promotes long-term reduction of HIV reservoir size. In patients with sustained virologic suppression, inflammation may be driven by non-HIV-related factors.

Intention to initiate antiretroviral therapy (ART) among people living with HIV in China under the scaling-up of ART: the role of healthcare workers' recommendations. BMC Health Serv Res 2019; 19:314. [PMID: 31096967 PMCID: PMC6524228 DOI: 10.1186/s12913-019-4143-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2019] [Accepted: 05/02/2019] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND The early initiation of antiretroviral therapy (ART) for people living with HIV (PLWH) benefits both individuals and societies. However, little is known about the intention to initiate ART among PLWH in China in the context of a scaling-up of treatment or how the recommendations of healthcare workers affect this intention. METHODS A total of 451 ART-naïve PLWH were recruited from communities in Guangzhou, China for this study. Data were collected by trained physicians via face-to-face interviews. Logistic regression models were fitted for the data analyses. RESULTS Of the participants, 93.8% were male, 72.7% were infected via homosexual behaviour and 68.5% reported an intention to initiate ART. In the latter category, 77.8, 41.9 and 20.0% of respondents received strong recommendations to initiate ART from healthcare workers at the Centres for Disease Control and Prevention (CDC), community healthcare centres and non-governmental organisations (NGOs), respectively. After adjusting for potential confounders, depression, anxiety and strong recommendations from healthcare workers at the CDC and NGOs correlated significantly with ART intention. In the adjusted final hierarchical logistic regression model, the duration of infection [multivariate odds ratio (ORm) = 0.30, p < 0.001], route of HIV infection (ORm = 0.18, p < 0.01), infection status of the current spouse/regular sex partner (ORm = 0.21-0.23, p < 0.01), anxiety (ORm = 2.44-2.65, p < 0.05) and strong recommendations from CDC physicians (ORm = 3.67, p < 0.01) or NGOs workers (ORm = 3.67, p < 0.01) were independently associated with the ART intention, whereas a recommendation from a community healthcare centre physician was not. CONCLUSIONS In Guangzhou, the prevalence of ART intention was below the 90-90-90 targets. Further studies aimed at an in-depth understanding and encouragement of health care workers' perceptions regarding early ART are warranted as a means of scaling up new ART strategies.

HIV treatment regimens and adherence to national guidelines in Australia: an analysis of dispensing data from the Australian pharmaceutical benefits scheme. BMC Public Health 2019; 19:13. [PMID: 30606134 PMCID: PMC6318998 DOI: 10.1186/s12889-018-6325-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2018] [Accepted: 12/14/2018] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND Treatment guidelines for antiretroviral therapy (ART) have evolved to emphasize newer regimens that address ageing-related comorbidities. Using national Australian dispensing data we compare ART regimens with Australian HIV treatment guidelines in the context of treated comorbidities. METHODS The study population included all individuals in a 10% sample of national data from the Australian Pharmaceutical Benefits Scheme (PBS) who purchased a prescription of ART during 2016. We defined each patient's most recently dispensed ART regimen and characterized them to evaluate regimen complexity and adherence to national HIV treatment guidelines. We then analyzed ART regimens in the context of other co-prescriptions purchased for defined comorbidities. RESULTS The 1995 patients in our sample purchased 212 different ART regimens during 2016; 1524 (76.4%) purchased one of the top ten most common regimens of which 62.3% were integrase strand transfer inhibitor-based. Among the 1786 (90%) patients that purchased the most common regimens, 83.7% purchased a regimen recommended by the guidelines for initial antiretroviral therapy and 11.4% purchased antiretrovirals that are not recommended for initial therapy; < 1% of the entire cohort purchased medications not recommended for use. While most patients purchased optimal ART regimens with low potential for significant drug interactions, regimen choices in the setting of risk factors for heart disease, renal disease and low bone mineral density appeared suboptimal. CONCLUSIONS Australian HIV providers are prescribing ART regimens in accordance with updated treatment guidelines, but could further optimize regimens in the setting of important medical comorbidities.

Which antiretrovirals should be prescribed as first-line treatments? Changes over the past 10 years in France. Med Mal Infect 2018; 49:264-269. [PMID: 30409541 DOI: 10.1016/j.medmal.2018.10.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2017] [Revised: 09/18/2017] [Accepted: 10/12/2018] [Indexed: 10/27/2022]
Abstract
OBJECTIVE To describe the changes in first-line antiretroviral (ART) regimens in France between 2005 and 2015 and patients' characteristics related to the use of protease inhibitors in 2015. METHODS We extracted all patients starting ART between 2005 and 2015 from a large prospective cohort. Regimens were classified as three nucleoside reverse transcriptase inhibitors (NRTI), or two NRTIs with a boosted protease inhibitor (bPI), with a non-nucleoside reverse transcriptase inhibitor (NNRTI), or with an INSTI. Patients' characteristics at the time of initiation were collected. A multinomial logit model was fitted to analyze characteristics related to the choice of regimen in 2015. RESULTS We analyzed data from 15,897 patients. The proportion of patients starting with (i) a bPI decreased from 60% before 2014 to 38.1% in 2015; (ii) an NNRTI decreased from 30% to 17.8% in 2015; (iii) an INSTI gradually increased to 39.4% in 2015. In 2015, patients with an initial viral load ˃5 log copies/mL were less likely to receive NNRTI (OR=0.08) or INSTI regimens (OR=0.69) than bPIs. Patients with initial CD4+ T cell count ˂200/mm3 were less likely to receive an NNRTI (OR=0.28) or an INSTI regimen (OR=0.52) than a bPI. Women were less likely to receive an NNRTI (OR=0.79) or an INSTI regimen (OR=0.71) than a bPI; although this depended on age. CONCLUSION The use of bPI as first-line ART declined sharply in France from 2005 to 2015. bPI remained of preferential use in patients with high viral load, low CD4+ T cell count, and in women.

Abstract
Background The natural clinical and immunological courses following HIV seroconversion with CXCR4-tropic or dual-mixed (X4/DM) viruses are controversial. We compared spontaneous immunological outcome in patients harbouring an X4/DM virus at the time of seroconversion with those harbouring a CCR5-tropic (R5) virus. Methods Data were included from patients participating in CASCADE, a large cohort collaboration of HIV seroconverters, with ≥2 years of follow-up since seroconversion. The HIV envelope gene was sequenced from frozen plasma samples collected at enrolment, and HIV tropism was determined using Geno2Pheno (false-positive rate 10%). The spontaneous CD4 T cell evolution was compared by modelling CD4 kinetics using linear mixed-effects models with random intercept and random slope. Results A total of 1387 patients were eligible. Median time between seroconversion and enrolment was 1 month (range 0-3). At enrolment, 202 of 1387 (15%) harboured an X4/DM-tropic virus. CD4 decrease slopes were not significantly different according to HIV-1 tropism during the first 30 months after seroconversion. No marked change in these results was found after adjusting for age, year of seroconversion and baseline HIV viral load. Time to antiretroviral treatment initiation was not statistically different between patients harbouring an R5 (20.76 months) and those harbouring an X4/DM-tropic virus (22.86 months, logrank test P = 0.32). Conclusions: In this large cohort collaboration, 15% of the patients harboured an X4/DM virus close to HIV seroconversion. Patients harbouring X4/DM-tropic viruses close to seroconversion did not have an increased risk of disease progression, estimated by the decline in CD4 T cell count or time to combined ART initiation.

Abstract
OBJECTIVE To examine whether there have been recent changes in Australian antiretroviral treatment (ART) prescribers' perceptions and practices relating to early ART initiation, which was defined as commencing ART when a patient's CD4+ T-cell count approaches 500 cells/mm3 or immediately after a patient is diagnosed with HIV. DESIGN, PARTICIPANTS AND SETTING Self-completed, anonymous, cross-sectional surveys, targeting all ART prescribers in Australia, were conducted online in 2012 and 2013. The surveys included questions on prescriber factors, CD4+ T-cell count at which prescribers would most strongly recommend ART initiation, and perceived patient characteristics that could change prescribers' practices of early initiation of ART. MAIN OUTCOME MEASURES Proportions of ART prescribers recommending early ART initiation. RESULTS We analysed responses from 108 participants in 2012 and 82 participants in 2013. In both years, more male than female prescribers participated. The median age of participants was 49 years in 2012 and 50 years in 2013. In both rounds, over 60% had more than 10 years' experience in treating HIV-positive patients. More prescribers in 2013 stated that they would most strongly recommend early ART initiation compared with those in 2012 (50.0% [95% CI, 38.7%-61.3%] v 26.9% [95% CI, 18.8%-36.2%]; P=0.001). The prescribers' primary concern was more about individual patient than public health benefit. Out of 824 patients for whom ART was initiated, as reported by prescribers in 2013, only 108 (13.1% [95% CI, 10.9%-15.6%]) were given ART primarily to prevent onward HIV transmission. The number of patients for whom ART was initiated was significantly associated with prescribers' HIV caseload even after adjusting for prescriber type (adjusted odds ratio, 1.73 [95% CI, 1.47-2.03]; P<0.001); of the 37 who had initiated ART for 10 or more patients, 29 had a high HIV caseload. In 2013, 60 prescribers (73.2% [95% CI, 62.2%-82.4%]) reported that they routinely recommended ART to treatment-naive, asymptomatic patients with a CD4+ T-cell count of 350-500 cells/mm3. CONCLUSION Our findings show increasing acceptance of and support for early ART initiation primarily as treatment and not as prevention.

Does transient cART started during primary HIV infection undermine the long-term immunologic and virologic response on cART resumption? BMC Infect Dis 2015; 15:178. [PMID: 25888386 PMCID: PMC4403722 DOI: 10.1186/s12879-015-0892-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2014] [Accepted: 03/12/2015] [Indexed: 12/24/2022] Open
Abstract
Background We explored the impact of transient cART started during the primary HIV-infection (PHI) on the long-term immunologic and virologic response on cART resumption, by comparison with treatment initiation during the chronic phase of HIV infection (CHI). Methods We analyzed data on 1450 patients enrolled during PHI in the ANRS PRIMO cohort between 1996 and 2013. “Treatment resumption” was defined as at least 3 months of resumed treatment following interruption of at least 1 month of treatment initiated during PHI. “Treatment initiation during CHI” was defined as cART initiated ≥6 months after PHI. The virologic response to resumed treatment and to treatment initiated during CHI was analyzed with survival models. The CD4 cell count dynamics was modeled with piecewise linear mixed models. Results 136 patients who resumed cART for a median (IQR) of 32 (18–51) months were compared with 377 patients who started cART during CHI for a median of 45 (22–57) months. Most patients (97%) achieved HIV-RNA <50 cp/mL after similar times in the two groups. The CD4 cell count rose similarly in the two groups during the first 12 months. However, after 12 months, patients who started cART during CHI had a better immunological response than those who resumed cART (p = 0.01); therefore, at 36 months, the gains in √CD4 cells/mm3 and CD4% were significantly greater in patients who started treatment during CHI. Conclusion These results suggest that interruption of cART started during PHI has a significant, albeit modest negative impact on CD4 cell recovery on cART resumption.

Influence of lifelong cumulative HIV viremia on long-term recovery of CD4+ cell count and CD4+/CD8+ ratio among patients on combination antiretroviral therapy. AIDS 2015; 29:595-607.

Abstract
OBJECTIVE We explored the impact of lifelong cumulative HIV viremia on immunological recovery during antiretroviral therapy, according to the timing of treatment initiation. METHODS We estimated lifelong cumulative HIV viremia in patients followed in the ANRS PRIMO cohort since primary infection, including 244 patients who started treatment during PHI and had at least one treatment interruption, and 218 patients who started treatment later but with no interruptions. The impact of cumulative viremia on current immunological status was analysed using linear and logistic regression models. RESULTS At the last visit on treatment, median CD4 cell count was 645 cells/μl in the early/intermittent treatment group (median time from infection 9.5 years, 4.8 years of continuous treatment since last resumption), and 654 cells/μl in the deferred/continuous treatment group (median time from infection 6.1 years, 3.0 years of continuous treatment). Only 36.1 and 39.8% of patients achieved a CD4/CD8 ratio of more than 1, respectively. Current CD4 cell count was not associated with cumulative HIV viremia in either group. In contrast, patients with high cumulative HIV viremia (>66th percentile vs. <33rd percentile) were less likely to achieve a CD4/CD8 ratio of more than 1 (26.8 vs. 43.3%, P = 0.003), even after controlling for the baseline CD4/CD8 ratio, treatment duration, sex and age. Much higher CD4 cell count and CD4/CD8 ratio were reached in early/continuous treatment, that is low viremia exposure group. CONCLUSION Our results underline the critical need in early-treated patients to maintain adherence, in order to limit cumulative HIV viremia and optimize immunological recovery, notably the CD4/CD8 ratio.

Abstract
The soluble CD14 (sCD14) level was found associated with mortality during the chronic phase of human immunodeficiency virus (HIV) infection. Here we assessed its prognostic value in 138 patients with primary HIV infection. Higher sCD14 levels were associated with death, from myocardial infarction, but this was based on 3 deaths only. Among 68 untreated patients, those with higher sCD14 levels had more rapid spontaneous CD4 cell decline during the first 18 months following primary infection. This association persisted after adjustment for age, the CD4 cell count, and HIV viral load at diagnosis.

Abstract
This systematic review was undertaken to determine the extent to which adult subjects representing sex (female), race (nonwhite), and age (>50 years) categories are included in clinical studies of HIV curative interventions and thus, by extension, the potential for data to be analyzed that may shed light on the influence of such demographic variables on safety and/or efficacy. English-language publications retrieved from PubMed and from references of retrieved papers describing clinical studies of curative interventions were read and demographic, recruitment year, and intervention-type details were noted. Variables of interest included participation by sex, age, and race; changes in participation rates by recruitment year; and differences in participation by intervention type. Of 151 publications, 23% reported full demographic data of study enrollees, and only 6% reported conducting efficacy analyses by demographic variables. Included studies recruited participants from 1991 to 2011. No study conducted safety analyses by demographic variables. The representation of women, older people, and nonwhites did not reflect national or international burdens of HIV infection. Participation of demographic subgroups differed by intervention type and study location. Rates of participation of demographic groups of interest did not vary with time. Limited data suggest efficacy, particularly of early therapy initiation followed by treatment interruption, may vary by demographic variables, in this case sex. More data are needed to determine associations between demographic characteristics and safety/efficacy of curative interventions. Studies should be powered to conduct such analyses and cure-relevant measures should be standardized.

Abstract
Since the discovery of HIV as the causative agent of AIDS in 1983/1984, remarkable progress has been made in finding antiretroviral drugs (ARVs) that are effective against it. A major breakthrough occurred in 1996 when it was found that triple drug therapy (HAART) could durably suppress viral replication to minimal levels. It was then widely felt, however, that HAART was too expensive and complex for low- and middle-income countries, and so, with the exception of a few of these countries, such as Brazil, a massive scale-up did not begin until the WHO launched its '3 by 5' initiative and sizeable funding mechanisms, such as the Global Fund to Fight AIDS, TB and Malaria and the US President's Emergency Plan for AIDS Relief (PEPFAR), came into existence. A pivotal enabler of the scale-up was a steady lowering of drug prices through entry of generic antiretrovirals, competition between generic manufacturers and the making of volume commitments. The WHO Prequalification of Medicines Programme and the Expedited Review Provision of the US Food and Drug Administration have been important for the assurance of quality standards. Antiretroviral drug development by research-based pharmaceutical companies continues, with several important innovative products, such as long-acting agents, in the pipeline.
