Abstract

International audience; It is unknown how past and active hepatitis B virus (HBV) infection affect immunorecovery and mortality in people with HIV who initiate tenofovir‐based antiretroviral therapy (ART). Using data collected between 2008 and 2015, we studied people with HIV in sub‐Saharan Africa initiating immediate ART in the Temprano randomized control trial. We classified participants into HBV groups at ART initiation: hepatitis B surface antigen (HBsAg)‐positive with HBV DNA ≥ 2,000 IU/ml; HBsAg‐positive with HBV DNA < 2,000 IU/ml; isolated HBcAb‐positive; resolved infection (HBsAb‐positive/HBcAb‐positive); and HBV non‐immune/vaccinated (HBcAb‐negative). We compared square‐root CD4‐cell count increases using mixed‐effect, non‐linear regression adjusted for age, sex, baseline CD4 cell count, and HIV RNA. We compared all‐cause mortality using Bayesian parametric survival regression. Among 879 participants, 24 (2.7%) had HBsAg with high HBV DNA, 76 (8.6%) HBsAg with low HBV DNA, 325 (37.0%) isolated anti‐HBcAb, 226 (25.7%) resolved HBV infection and 228 (25.9%) HBV non‐immune/vaccinated. We found no significant difference in CD4 cell increases between HBV‐infection groups after adjustment (p = 0.16). Participants with HBsAg and high HBV DNA had the highest incidence of all‐cause mortality (1.9/100 person‐years, 95% Credibile Interval [CrI] = 1.0–3.4). By comparison, incidence rates of mortality were reduced by 57% (95%CrI = −79%, −13%), 60% (95%CrI = −82%, −12%) and 66% (95%CrI = −84%, −23%) in those who had isolated anti‐HBcAb‐positive, resolved HBV infection and HBV non‐immune/vaccinated, respectively. In conclusion, individuals with HIV and past HBV infection or isolated anti‐HBcAb‐positive serology, much like HBV non‐immune/vaccinated, experience lower mortality than those with HBsAg and high HBV DNA. Additional HBV‐related management would not be necessary for these individuals.

Abstract

Research component of the ATLAS programmeThe ATLAS programme (2019-2021) aims to promote and deploy HIV self-testing (HIVST) in Côte d'Ivoire, Mali and Senegal and to distribute half a million HIVST through various delivery channels, targeting in particular key populations (sex workers, men who have sex with men, drug users), partners of people living with HIV (PLHIV) and patients with sexually transmitted infections. The dispensation of HIVST will be carried out in routine care, through the three countries' national AIDS strategies and in an integrated manner with existing screening policies, through eight delivery channels combining fixed and advanced strategies, primary distribution and secondary distribution. The research component presented here includes a set of observational surveys to describe, analyze and understand the social, health, epidemiological and economic effects of the introduction of HIVST in Côte d'Ivoire, Mali and Senegal to improve testing offer (accessibility, effectiveness and ethics). It is organized into 5 work packages: (i) a qualitative survey on HIVST targeted key populations, based on qualitative individual and group interviews with key implementers, members of key population communities and HIVST users; (ii) an ethnography on the integration of HIVST for screening of PLHIV’s partners in three HIV care clinics and an exploratory sub-survey on HIVST distribution in STI consultations; (iii) an anonymous telephone survey of HIVST users recruited through an invitation on HIVST kits to call a toll-free number; (iv) an economic survey of HIVST incremental costs with cost collections from a sample of HIVST dispensing sites and a time and motion study; (v) an epidemiological modelling (dynamic compartmental model) of the three countries and of the health and economic impacts of different scaling scenarios.; Volet recherche du programme ATLASLe programme ATLAS (2019-2021) vise à promouvoir et à déployer l’autodépistage du VIH (ADVIH) en Côte d’Ivoire, au Mali et au Sénégal et prévoit la distribution d’un demi millions d’autotests à travers différents canaux de dispensation, visant en particulier les populations clés (travailleuses du sexe, hommes ayant des rapports sexuels avec des hommes, usager·e·s de drogues), les partenaires des personnes vivant avec le VIH (PvVIH) et les patient·e·s atteint·e·s d’une infection sexuellement transmissible. La dispensation des kits d’ADVIH sera réalisée en soins courants, dans le cadre des stratégies nationales de lutte contre le sida des trois pays et de manière intégrée aux politiques de dépistage déjà en place, à travers huit canaux de dispensation combinant des stratégies fixes et des stratégies avancées, une distribution primaire et une distribution secondaire. Le volet recherche présenté ici comporte un ensemble d’enquêtes observationnelles visant à décrire, analyser et comprendre les effets sociaux, sanitaires, épidémiologiques et économiques de l’introduction de l’autodépistage du VIH en Côte d’Ivoire, au Mali et au Sénégal pour améliorer l’offre de dépistage (accessibilité, efficacité et éthique). Il est organisé en 5 paquets d’activités : (i) une enquête qualitative sur l’ADVIH auprès des populations clés reposant sur des entretiens qualitatifs individuels et de groupes auprès d’acteurs clés de la mise en œuvre, de membres des communautés de populations clés et d’utilisatrices et utilisateurs de l’ADVIH ; (ii) une ethnographie portant sur l’intégration de l’ADVIH pour le dépistage des partenaires de PvVIH dans trois sites de prise en charge du VIH et une sous enquête exploratoire portant sur la diffusion de l’ADVIH à travers les consultations IST ; (iii) une enquête téléphonique anonyme auprès des utilisatrices et utilisateurs de l’ADVIH recruté·e·s via une invitation à appeler un numéro vert apposée sur les kits d’ADVIH distribués ; (iv) une enquête économique des coûts incrémentiels de l’ADVIH avec une collecte des coûts auprès d’un échantillon de sites de dispensation de l’ADVIH et une étude des temps et mouvements ; (v) une modélisation épidémiologique (modèle compartimental dynamique) des trois pays et des impacts sanitaires et économiques de différents scénarios de passage à l’échelle.

Abstract

International audience; BACKGROUND & AIMS: Replication markers exhibit substantial variation during chronic hepatitis B virus (HBV) infection, part of which can be explained by mutations on the surface (S) gene. We aimed to identify S-gene mutations possibly influencing the quantification of HBV replication markers (MUPIQH) in HBV genotype E infection, common to Western Africa.METHODS: Seventy-three antiretroviral treatment (ART)-naïve human immunodeficiency virus (HIV)-HBV co-infected patients from Côte d'Ivoire, initiating anti-HBV-containing ART, had available HBV S-gene sequences. S-gene MUPIQHs were screened at ART initiation based on lower HBV-DNA or HBsAg quantification (qHBsAg) compared to wildtype. Their association with HBV virological response and qHBsAg slope during treatment was evaluated.RESULTS: Genotype E was predominant (95.9%). At ART initiation, median HBV-DNA was 7.27 log10 copies/mL (IQR = 5.26-8.33) and qHBsAg 4.08 log10 IU/mL (IQR = 3.49-4.61). Twelve S-gene MUPIQHs were identified among 21 patients (28.8%): sS140L (n = 4), sD144A (n = 1), sS167L (n = 2), sS174N (n = 6), sP178Q (n = 2), sG185L (n = 2), sW191L (n = 2), sP203Q/R (n = 2), sS204N/I/R/K/T/G (n = 7), sN207T (n = 2), sF212C (n = 1) and sV224A/Y (n = 7). MUPIQHs at positions s185+s191+s224 and s178+s204 were within highly covarying networks of S-gene mutations. Older age (P = 0.02), elevated transaminases (P = 0.03) and anti-hepatitis B "e" antibody-positive serology (P = 0.009) were significantly associated with prevalent MUPIQHs at ART initiation. During treatment, baseline MUPIQHs were not associated with time-to-undetectable HBV-DNA (P = 0.7) and qHBsAg levels decreased at similar rates between those with vs without MUPIQHs (P = 0.5).CONCLUSION: Several novel S-gene mutations were associated with reductions in replication markers among West African co-infected patients. These mutations, however, do not affect response during antiviral treatment. Their diagnostic and clinical consequences need clarification.

Abstract

Background: In HIV-infected patients, hepatitis B virus (HBV)-coinfection increases the risk of disease progression. Tenofovir+emtricitabine/lamivudine (TDF/XTC)-based antiretroviral therapy (ART), which suppresses HIV and HBV replication, has the potential for decreasing this risk. Here, we analyze the association between HBV replication, early-ART, and mortality in West-African adults. Methods: The Temprano randomized-control trial assessed the benefits of immediately initiating versus deferring ART in HIV-infected adults with high CD4 counts. After trial completion, participants continued follow-up in a post-trial phase. We analyzed the association between HBV-status, immediate-ART, and mortality over the entire trial and post-trial follow-up using multivariable Cox proportional hazards regression. Results: 2052 HIV-infected adults (median baseline CD4=464/mm3) were followed for 9394 person-years. At baseline, 1862 (91%) were HIV-monoinfected and 190 (9%) HIV-HBV-coinfected. Of the latter, 135 (71%) had plasma HBV-DNA /=2000 IU/ml. The 60-month probability of death was 11.8% (95%CI=5.4-24.5) in coinfected patients with HBV-DNA >/=2000 IU/ml, 4.4% (95%CI=1.9-10.4) in coinfected patients with HBV-DNA /=2000 IU/ml and 0.90 (95%CI=0.36-2.24) in coinfected patients with HBV-DNA

Abstract

International audience; The nucleotide substitution G1896A on the precore (pc) region has been implicated in virological and serological responses during treatment in hepatitis B virus (HBV)‐infected patients. Whether this mutation affects the therapeutic course of HIV‐HBV co‐infected patients, especially from Western Africa, is unknown. In this prospective cohort study, 86 antiretroviral (ARV)‐naïve HIV‐HBV co‐infected patients from Côte d'Ivoire, initiating ARV‐treatment containing lamivudine (n = 53) or tenofovir (n = 33), had available baseline pc sequences. Association of the pcG1896A mutation with time to undetectable HBV‐DNA, hepatitis B “e” antigen (HBeAg) seroclearance (in HBeAg‐positive patients), and hepatitis B surface antigen (HBsAg) seroclearance was evaluated using Cox proportional hazards regression. At ARV‐initiation, median HBV‐DNA was 6.04 log10 copies/mL (IQR = 3.70‐7.93) with 97.7% harbouring HBV genotype E. Baseline pcG1896A mutation was identified in 51 (59.3%) patients, who were more commonly HBeAg‐negative (P < .001) and had basal core promotor A1762T/G1764A mutations (P < .001). Patients were followed for a median 36 months (IQR = 24‐36). Cumulative proportion of undetectable HBV‐DNA was significantly higher in patients with baseline mutation (pcG1896A = 86.6% vs no pcG1896A = 66.9%, P = .04), but not after adjusting for baseline HBV‐DNA levels and anti‐HBV agent (P = .2). No difference in cumulative proportion of HBeAg seroclearance was observed between mutation groups (pcG1896A = 57.1% vs no pcG1896A = 54.3%, P = .7). Significantly higher cumulative proportion of HBsAg seroclearance was observed in patients without this mutation (pcG1896A = 0% vs no pcG1896A = 36.9%, P < .001), even after adjusting for baseline HBsAg quantification and anti‐HBV agent (P < .001). In conclusion, lacking the pcG1896A mutation before ARV initiation appeared to increase HBsAg seroclearance rates during treatment. The therapeutic implications of this mutation need further exploration in this setting.

Abstract

International audience; Based on social indicators collected within the TEMPRANO-ANRS12136 trial, we assessed the social consequences of early antiretroviral therapy (ART) initiation in west Africa. We did not observe any significant differences in the levels or the time trends of various social indicators, including union status, HIV disclosure and HIV-related discrimination, between early and deferred ART initiation. Early ART does not carry detectable adverse social consequences that could impair its clinical and preventive benefits.

Abstract

International audience; AbstractBackground and AimIn Sub-Saharan Africa, seroclearance of hepatitis B surface antigen (HBsAg) and hepatitis B “e” antigen (HBeAg), including their quantifiable markers, have rarely been evaluated during long-term antiviral treatment among patients coinfected with HIV and hepatitis B virus (HBV).MethodsIn this prospective cohort study from two randomized-control trials in Côte d'Ivoire, 161 antiretroviral-naïve HIV-HBV coinfected patients starting lamivudine (n = 76) or tenofovir/emtricitabine (n = 85) containing antiretroviral therapy were included. HBV DNA was quantified using an in-house assay (detection limit = 12 copies/mL) and HBsAg quantification (qHBsAg) using the Elecsys assay.ResultsOverall, 33 (20.5%) patients were HBeAg positive, 121 (75.2%) had detectable HBV DNA, and 92/93 (98.9%) harbored HBV genotype E. Median treatment duration was 35.5 months (interquartile range: 24.3–36.4). Among HBeAg-positive patients, cumulative proportion with HBeAg seroclearance was 46.3% (n = 14). Overall, cumulative proportion of HBsAg seroclearance was 6.6% (n = 10). Lower baseline qHBsAg levels and strong 12-month declines in qHBsAg were significantly associated with HBsAg seroclearance for both HBeAg-negative and HBeAg-positive patients. When taken at certain levels, these determinants provided moderate sensitivity (Se) and specificity (Sp) in predicting HBsAg seroclearance at month 36 (≤ 1000 IU/mL at baseline, Se = 0.80, Sp = 0.80; ≥ 1.0 log10 IU/mL drop at month 12, Se = 0.57, Sp = 1.00). Instead, qHBsAg levels ≤ 100 or ≤ 10 IU/mL at month 12 were optimal (both Se = 0.90 and Sp = 1.00). Detectable HBV-DNA provided fairly high Se and Sp when evaluated at baseline (Se = 1.00, Sp = 0.80), but not at month 12 (Se = 0.80, Sp = 0.40).ConclusionsHBsAg seroclearance rates are not common in patients from Sub-Saharan Africa treated with anti-HBV containing antiretroviral therapy. qHBsAg levels at 12 months of treatment may accurately predict HBsAg seroclearance.

Abstract

International audience; Introduction: Whether early antiretroviral therapy (ART) initiation could impact sexual risk behaviours remains to be documented. We aimed to investigate changes in sexual behaviours within the 24 months following an early versus standard ART initiation in HIV-positive adults with high CD4 counts. Methods: We used data from a prospective behavioural study nested in a randomized controlled trial of early ART (Temprano-ANRS12136). Time trends in sexual behaviours from enrolment in the trial (M0) to 12-month (M12) and 24-month (M24) visits were measured and compared, using Generalized Estimating Equations models, between participants randomly assigned either to initiate ART immediately (early ART) or to defer ART initiation until on-going WHO starting criteria are met (standard ART). Indicators of sexual behaviours included 1) sexual activity in the past year, 2) multiple partnership in the past year, 3) unprotected sex at last intercourse and 4) risky sex (i.e. unprotected sex with a partner of HIV negative/unknown status) at last intercourse. Results: Analyses included 1952 participants (975 with early ART and 977 with standard ART; overall median baseline CD4 count: 469/mm(3)). Among participants with early ART, significant decreases were found between M0 and M24 in sexual activity (Odds Ratio [OR] 0.72, 95% Confidence Interval [95% CI] 0.57-0.92), multiple partnership (OR 0.57, 95% CI 0.41-0.79), unprotected sex (OR 0.59, 95% CI 0.47-0.75) and risky sex (OR 0.58, 95% CI 0.45-0.76). Among participants with standard ART, sexual behaviours showed similar trends over time. These decreases mostly occurred within the 12 months following enrolment in the trial in both groups and prior to ART initiation in participants with standard ART. For unprotected sex and risky sex, decreases were or tended to be more pronounced among patients reporting that their last sexual partner was non-cohabiting. Conclusions: In these sub-Saharan adults with high CD4 counts, entry into HIV care, rather than ART initiation, resulted in decreased sexual activity and risky sexual behaviours. We did not observe any evidence of a risk compensation phenomenon associated with early ART initiation. These results illustrate the potential behavioural preventive effect of early entry into care, which goes hand in hand with early ART initiation.

Abstract

International audience; Background. The effect of early antiretroviral therapy (ART) on sexual behaviors and HIV-1 transmission risk has not been documented beyond the specific population of stable serodiscordant couples.Methods. Based on a behavioral study nested in a randomized controlled trial (Temprano-ANRS12136) of early ART, we compared proportions of risky sex (unprotected sex with a partner of negative/unknown HIV status) reported 12 months after inclusion between participants randomized to initiate ART immediately ('early ART') or according to WHO criteria ('standard ART'). Group-specific HIV-transmission rates were estimated based on sexual behaviors and viral load-specific per-act HIV-1 transmission probabilities. Their ratio was computed to estimate the protective effect of early ART.Results. Among 957 participants (baseline CD4: 478/mm(3)), 46.0% reported sexual activity in the past month, 41.5% of them with non-cohabiting partners. Proportion of risky sex was 10.0% vs. 12.8%, respectively, in participants on early vs. standard ART (p=0.17). Accounting for sexual behaviors and viral load, the estimated protective effect of early ART was 90% (95%CI 81-95%).Conclusion. Twelve months after inclusion, patients on early and standard ART reported similar sexual behaviors. Early ART decreased the estimated risk of HIV transmission by 90%, suggesting a major prevention benefit among both stable and casual partners.

Abstract

International audience; objective To investigate the relationship between unsafe sexual behaviours and poor self-perceivedhealth among people living with HIV and AIDS (PLWHA) in western Africa.methods In March 2006, a survey was conducted among patients continuing their participation in theTRIVACAN trial (ANRS 1269) in Coˆ te d’Ivoire, in which patients had been randomized to eithercontinuous or interrupted antiretroviral therapy (ART) (2-months-off ⁄ 4-months-on cycles [2 ⁄ 4-ART])after 6–18 months of continuous ART (C-ART). Socio-demographic and psychosocial information,including data on sexual behaviours during the previous 6 months, was collected using face-to-faceinterviews. Sexually active patients with either a steady partner (serodiscordant or of unknown HIVstatus) or casual partners were considered to have unsafe sexual behaviours if they reported inconsistentcondom use (ICU).results Seventy-seven of the 192 patients reported ICU. In multivariate logistic regression, men weresignificantly less likely to report ICU than women (OR [95% CI] = 0.45 [0.20–0.98]). After adjustment foreducational level and reduced sexual activity since ART initiation, concealment of HIV status (2.08 [1.02–4.25]) and poor self-perceived health (2.32 [0.97–5.52]) were independently associated with ICU.conclusion HIV prevention strategies in resource-limited settings should take into account self-perceivedhealth and difficulties to disclose HIV status. Counselling interventions need to be developed tohelp PLWHA to adopt or negotiate safe behaviours respecting their individual cultures.

Abstract

International audience; OBJECTIVE: The 6 month assessment of the response to antiretroviral therapy (ART) is a critical step. In sub-Saharan Africa, few people have access to plasma viral-load measurement. We assessed the gain or loss in body mass index (BMI), alone or in combination with the gain or loss in CD4+ T-cell count (CD4), as a tool for predicting the response to ART. METHODS: In a cohort of 622 adults in Abidjan, C?d'Ivoire, we calculated the sensitivity, specificity and predictive values of BMI and CD4 for treatment success defined as viral-load undetectability (< 300 copies/ml) as gold standard. FINDINGS: After 6 months of ART, the median change in BMI was an increase of 1.0 kg/m(2) (interquartile range, IQR: 0.0-2.1), the median change in CD4 an increase of 148/ml (IQR: 54-230) and 84% of patients reached viral-load undetectability. The distribution of change in BMI was similar among patients who reached undetectability and those who did not (increases of 1.06 kg/m(2) versus 0.99 kg/m(2), P = 0.51). With larger changes in BMI, the specificity for treatment success increased but its sensitivity decreased and its positive predictive value was stable around 85%. All results remained similar when combining changes in BMI with those in CD4 and when stratifying by groups of baseline BMI or CD4. CONCLUSION: In settings where viral-load measurement is not available, a high BMI gain does not reflect virological success, even when combined with a high CD4 gain. In our population, most patients with detectable viral-load had probably adhered to the drug regimen sufficiently to reach significant gains in body mass and CD4 count but had adhered insufficiently to reach viral suppression.

International audience; OBJECTIVE: To estimate the incidence and risk factors of mortality and severe morbidity during the first months following antiretroviral therapy (ART) initiation in West African adults. METHODS: A cohort study in Abidjan in which 792 adults started ART with a median CD4 cell count of 252 cells/mul and were followed for a median of 8 months. Severe morbidity was defined as all World Health Organization stage 3 or 4-defining morbidity events other than oral candidiasis. RESULTS: In patients with pre-ART CD4 cell count < 200, at 200-350 and > 350 cells/mul, incidence of mortality was 5.0 [95% confidence interval (CI), 2.6-8.7], 1.7 (95% CI, 0.6-3.8) and 0.0 (95% CI, 0.0-3.4]/100 person-years, and incidence of severe morbidity was 13.3 (95% CI, 9.0-19.1), 9.5 (95% CI, 6.2-12.9) and 7.9 (95% CI, 3.4-15.5)/100 person-years, respectively. The most frequent diseases were invasive bacterial diseases (32/65 episodes, 49%) and tuberculosis (25/65 episodes, 38%). Both diseases followed the same curve of decreasing incidence over time. Patients who experienced severe morbidity had higher risks of mortality, virological failure and immunological failure. Other independent risk factors for mortality and/or severe morbidity were: at baseline, high viral load, advanced clinical stage, past history of tuberculosis, low BMI, low haemoglobin and low CD4 cell count; during follow-up: low CD4 cell count and persistently detectable viral load. CONCLUSION: These data give new arguments to reinforce the hypothesis that, in this region, ART should be started before the CD4 cell count drops below 350 cells/mul. Further studies should assess whether patients with low BMI, low haemoglobin, high viral load or past history of tuberculosis should start ART earlier.

Abstract

Background The ATLAS programme aims to promote and implement HIV self-testing (HIVST) in three West African countries: Côte d’Ivoire, Mali, and Senegal. During 2019–2021, in close collaboration with the national AIDS implementing partners and communities, ATLAS plans to distribute 500,000 HIVST kits through eight delivery channels, combining facility-based, community-based strategies, primary and secondary distribution of HIVST. Considering the characteristics of West African HIV epidemics, the targets of the ATLAS programme are hard-to-reach populations: key populations (female sex workers, men who have sex with men, and drug users), their clients or sexual partners, partners of people living with HIV and patients diagnosed with sexually transmitted infections and their partners. The ATLAS programme includes research support implementation to generate evidence for HIVST scale-up in West Africa. The main objective is to describe, analyse and understand the social, health, epidemiological effects and cost-effectiveness of HIVST introduction in Côte d’Ivoire, Mali and Senegal to improve the overall HIV testing strategy (accessibility, efficacy, ethics). Methods ATLAS research is organised into five multidisciplinary workpackages (WPs): Key Populations WP: qualitative surveys (individual in-depth interviews, focus group discussions) conducted with key actors, key populations, and HIVST users.Index testing WP: ethnographic observation of three HIV care services introducing HIVST for partner testing.Coupons survey WP: an anonymous telephone survey of HIVST users.Cost study WP: incremental economic cost analysis of each delivery model using a top-down costing with programmatic data, complemented by a bottom-up costing of a representative sample of HIVST distribution sites, and a time-motion study for health professionals providing HIVST.Modelling WP: Adaptation, parameterisation and calibration of a dynamic compartmental model that considers the varied populations targeted by the ATLAS programme and the different testing modalities and strategies. Discussion ATLAS is the first comprehensive study on HIV self-testing in West Africa. The ATLAS programme focuses particularly on the secondary distribution of HIVST. This protocol was approved by three national ethic committees and the WHO’s Ethical Research Committee.
