Effect of isoniazid preventive therapy on risk of death in west African, HIV-infected adults with high CD4 cell counts: long-term follow-up of the Temprano ANRS 12136 trial

Temprano ANRS 12136 was a factorial 2 × 2 trial that assessed the benefits of early antiretroviral therapy (ART; ie, in patients who had not reached the CD4 cell count threshold used to recommend starting ART, as per the WHO guidelines that were the standard during the study period) and 6-month isoniazid preventive therapy (IPT) in HIV-infected adults in Côte d'Ivoire. Early ART and IPT were shown to independently reduce the risk of severe morbidity at 30 months. Here, we present the efficacy of IPT in reducing mortality from the long-term follow-up of Temprano. Methods For Temprano, participants were randomly assigned to four groups (deferred ART, deferred ART plus IPT, early ART, or early ART plus IPT). Participants who completed the trial follow-up were invited to participate in a post-trial phase. The primary post-trial phase endpoint was death, as analysed by the intention-to-treat principle. We used Cox proportional models to compare all-cause mortality between the IPT and no IPT strategies from inclusion in Temprano to the end of the follow-up period. Findings Between March 18, 2008, and Jan 5, 2015, 2056 patients (mean baseline CD4 count 477 cells per μL) were followed up for 9404 patient-years (Temprano 4757; post-trial phase 4647). The median follow-up time was 4·9 years (IQR 3·3–5·8). 86 deaths were recorded (Temprano 47 deaths; post-trial phase 39 deaths), of which 34 were in patients randomly assigned IPT (6-year probability 4·1%, 95% CI 2·9–5·7) and 52 were in those randomly assigned no IPT (6·9%, 5·1–9·2). The hazard ratio of death in patients who had IPT compared with those who did not have IPT was 0·63 (95% CI, 0·41 to 0·97) after adjusting for the ART strategy (early vs deferred), and 0·61 (0·39–0·94) after adjustment for the ART strategy, baseline CD4 cell count, and other key characteristics. There was no evidence for statistical interaction between IPT and ART (pinteraction=0·77) or between IPT and time (pinteraction=0·94) on mortality. Interpretation In Côte d'Ivoire, where the incidence of tuberculosis was last reported as 159 per 100 000 people, 6 months of IPT has a durable protective effect in reducing mortality in HIV-infected people, even in people with high CD4 cell counts and who have started ART

Dissection aortique anevrismale chez un adulte infecte par le VIH-1 dans le cadre d'un syndrome de reconstitution immune avec tuberculose

We here report the case of a 35-year old man with HIV-1 but with no previous medical-surgical history hospitalized in Abidjan, Cote d'Ivoire, due to fever, cough, dyspnea, chest pain and unfolding of the aortic arch observed on chest x-ray a week after having started antiretroviral therapy (ART). CT angiography of the thoracic aorta showed overall, extended aortic ectasia with mural thrombus. Transesophageal echocardiography objectified type A ascending aortic dissection (Stanford classification). The diagnosis of tuberculosis was confirmed based on Mycobacterium tuberculosis culture isolation. Eight years after, the patient was still alive without surgical treatment and complained of intermittent chest pain. Blood pressure was stable with moderate renal failure. We here report a rare case of aortic aneurism dissection in an adult patient with tuberculosis infected with HIV-1 during immune reconstitution inflammatory syndrome

EBioMedicine

Background High HIV-1 DNA levels in peripheral blood mononuclear cells (PBMC) were associated with a higher risk of severe morbidity and a faster decline in CD4 count in ART-naive patients. We report the association between HIV-1 DNA and mortality in HIV-infected adults in a trial of early ART in West Africa. Methods In the Temprano trial, HIV-infected adults were randomly assigned to start ART immediately or defer ART. After trial termination, HIV-1 DNA was measured in whole blood samples frozen at baseline. We analyzed the association between baseline PBMC HIV-1 DNA and long-term mortality

Primary Isoniazid Prophylaxis against Tuberculosis in the Era of Antiretroviral Therapy

Fléau mondial depuis des millénaires, la tuberculose (TB) a régressé dans la deuxième moitié du 20ème siècle avant de connaitre une résurgence à partir des années 1980 à la faveur de la pandémie du VIH. Les deux maladies se potentialisent mutuellement et forment un « couple infernal ». En Afrique, la TB est la première cause de mortalité des adultes infectés par le VIH, quel que soit leur niveau d’immunité. Une des mesures pour lutter contre la TB associée au VIH est la chimioprophylaxie, consistant à traiter une infection tuberculeuse latente pour prévenir l’évolution vers une TB maladie. La mieux évaluée, consiste à prescrire 6 à 12 mois de monothérapie d’isoniazide (Isoniazid Preventive Therapy, IPT). Depuis 1993, l’OMS recommande la prescription de 6 mois d’IPT chez toutes les personnes infectées par le VIH sans signe de TB active. Malgré des preuves scientifiques solides à l’appui de cette recommandation, l’utilisation de l’IPT est toujours restée faible. Avant notre travail, trois raisons expliquaient cette faiblesse : (i) la crainte qu’une chimioprophylaxie mal appliquée ne favorise l’émergence de résistances ; (ii) le fait que les essais avaient démontré l’efficacité de l’IPT pour réduire l’incidence de TB, pas pour réduire la mortalité ; (iii) le fait que les essais d’IPT avaient eu lieu en majorité avant l’ère des antirétroviraux (ARV), chez des personnes très immunodéprimées. Les ARV permettant également de réduire le risque de TB en faisant régresser l’immunodépression, certains considéraient que l’IPT était devenue inutile. Dans cette thèse nous faisons d’abord un rappel des connaissances essentielles sur l’infection par le VIH, la TB, l’association TB/VIH, et le concept de chimioprophylaxie antituberculeuse. Puis nous exposons les résultats de l’analyse du suivi prolongé de l’essai randomisé Temprano ANRS 12136, qui s’est déroulé entre 2008 et 2015. Cet essai a suivi 2056 adultes infectés par le VIH dans 9 centres de soins à Abidjan. Les participants qui avaient des CD4 élevés (moyenne 477/mm3) étaient randomisés en 4 bras pour étudier deux interventions : 6 mois d’IPT (reçu vs. non reçu) et ARV (début immédiat vs. début différé). Les participants ont été suivis pendant 4,9 ans en moyenne. 89% d’entre eux ont débuté des ARV. Pendant le suivi, il y a eu 86 décès, 34 dans le groupe avec IPT (probabilité à 6 ans : 4,1% ; IC95% 2,9–5,7) et 52 dans le groupe sans IPT (probabilité à 6 ans: 6,9% ; 5,1–9,2). Le Hazard ratio de décès dans le groupe avec IPT par rapport à l’autre groupe était 0,63 (95% CI 0,41-0,97). Il n’y avait pas d’interaction entre IPT et ARV précoce, ni entre IPT et le temps. Ces résultats ont été publiés dans The Lancet Global Health. Enfin nous discutons ces résultats avec ceux des essais d’IPT précédents, dans une revue critique de la littérature analysant les données d’efficacité et de tolérance, les déterminants de l’efficacité, et les risques de résistance. Nous montrons que l’essai Temprano complète et élargit le spectre des connaissances, et que les preuves scientifiques accumulées depuis 1993 jusqu’à l’essai Temprano inclus suggèrent que les ARV modifient certains paramètres de l’IPT qu’on pensait solidement établis. Avant l’ère des ARV on considérait que l’efficacité de l’IPT était forte chez les personnes avec IDR positive mais très faible voire inexistante chez les personnes avec IDR négative, qu’il y avait une perte d’efficacité de l’IPT au cours du temps et que l’IPT n’avait pas d’effet sur la mortalité. Avec les ARV, on voit que l’IPT est efficace quel que soit le résultat des tests tuberculiniques, que cette efficacité est prolongée, et qu’elle se traduit non seulement par une réduction de la TB mais aussi de la mortalité. L’IPT reste donc une intervention d’une grande actualité à l’ère des ARV. Ces résultats devraient convaincre les pays jusque-là réticents à appliquer les recommandations de l’OMS.Tuberculosis (TB) has been a worldwide scourge for millennia. It has regressed in the second half of the 20th century before resurging in the 1980s because of the HIV pandemic. Both diseases potentiate each other and form a "cursed duet". In Africa, TB is the leading cause of mortality among HIV-infected adults, regardless of their level of immunity. One of the measures to fight HIV-associated TB is chemoprophylaxis, which consists in treating latent TB infection to prevent the progression to TB disease. The most evaluated chemoprophylaxis, referred to as "Isoniazid Preventive Therapy" (IPT), consists in prescribing 6 to 12 months of isoniazid monotherapy. Since 1993, WHO recommends the prescription of 6 months of IPT in all HIV-infected persons who do not have evidence of active TB. Despite strong scientific evidence to support this recommendation, the use of IPT has remained low. Before our work, there were three reasons for this:(i) people feared that chemoprophylaxis might favor the emergence of resistance to TB drug; (ii) the IPT trials demonstrated the effectiveness of IPT in reducing TB incidence, not in reducing mortality; (iii) most IPT trials took place before the antiretroviral treatment (ART) era, in highly immunocompromised individuals. As ART also reduces the risk of TB by decreasing immunosuppression, some people considered that IPT had become useless. In this work, we first go over the basic knowledge about HIV infection, TB, the combination of the two diseases, and the concept of antituberculous chemoprophylaxis. Then we present the results of the long-term follow-up of the Temprano ANRS 12136 randomized trial, which took place between 2008 and 2015. This trial followed 2056 HIV infected adults in 9 care centers in Abidjan. Participants with high CD4 counts (mean: 477 cells/mm3) were randomized into 4 arms to study two interventions: 6 months of IPT (received vs. not received) and early ART (immediate initiation vs. delayed initiation). Participants were followed for an average of 4.9 years. Eighty nine percent of participants received ART. During follow-up, there were 86 deaths, 34 in patients randomized to IPT (6-year probability: 4.1%, 95% CI 2.9-5.7) and 52 in those randomized to no-IPT (6-year probability: 6.9%, 5.1-9.2). The Hazard ratio of deaths among those randomized to IPT compared to others was 0.63 (95% CI 0.41-0.97). There was no interaction between IPT and early ART, nor between IPT and time. These results were published in The Lancet Global Health. Finally, we discuss these results with those of previous IPT trials, after reviewing all available randomized-controlled evidence on efficacy, safety, efficacy determinants and risks of resistance. We show that the Temprano trial complements and widens the spectrum of evidence accumulated since 1993 and that ART modifies some key parameters of IPT previously thought to be strongly established. Prior to the ART era, evidence suggested that the efficacy of IPT was high in people with positive Tuberculin Skin Test (TST) but very low in those with negative TST; that there was a loss of IPT efficacy over time; and that IPT had no effect on mortality. With ART, IPT appears to be effective regardless of TST results, have prolonged efficacy, and reduce not only TB but also mortality. IPT remains a very topical intervention in the ART era. These results should convince IPT-reluctant countries to implement WHO recommendations

Community Health Workers. Reinforcement of an Outreach Strategy in Rural Areas Aimed at Improving the Integration of HIV, Tuberculosis and Malaria Prevention, Screening and Care Into the Health Systems. "Proxy-Sante" Study

International audienceBACKGROUND: In Côte d'Ivoire, the health system remains poorly accessible and inefficient, particularly in rural areas. Malaria, tuberculosis and HIV remain a major concern. Tasks shifting to Community Health Workers (CHWs) in rural areas has been proposed in terms of responses and has shown encouraging results with some limitations. Objective is therefore to develop and implement, in a health district, at the level of a neighborhood, a sub-prefecture, two villages and two camps, innovative strategies aimed at improving the integration of HIV, malaria and tuberculosis prevention and care into the health system at the community level through CHWs.METHODS: Introduce innovations to be integrated into the national system: (i) Selection and strengthening of the capacities of CHWs to provide care for the three diseases through home visits [Information Education and Counseling/Communication for Behavior Change (IEC/CBC)], simple malaria screening and management, referral of suspected tuberculosis cases and Directly Observed Treatment, short-course (DOTS), screening, prophylaxis and distribution of antiretrovirals (ARVs) to HIV-infected patients; (ii) monthly animation of village health committees by target groups (women of childbearing age, children under 5 years old, young adolescents); (iii) use of an application and tablets for data collection.DISCUSSION: This innovative project integrates new activities such as ARV distribution by CHWs, management of pre-exposure prophylaxis in rural areas and electronic data capture by communities. Several lessons can be learned on the relevance of the role and activities to be carried out by these CHWs in the fight against these three diseases

Aspects diagnostiques et cliniques de la tuberculose infantile : à propos de 94 cas colligés en milieu hospitalier à Abidjan, Côte d’Ivoire, de 2015 à 2017 Raoul

La tuberculose infantile (TBI) reste largement sous notifiée. La principale raison de la sous-notification est la difficulté diagnostique. Le diagnostic précoce et la prise en charge de la TBI demeurent donc un défi constant à relever. Il s’est agi d’une étude rétrospective portant sur les données issues des dossiers de 94 enfants de 0 à 14 ans diagnostiqués pour une tuberculose du 1er janvier 2015 au 31 décembre 2017 dans deux centres hospitaliers et universitaires d’Abidjan. Ainsi, la tranche d’âge de 0 à 4 ans était la plus représentée. La localisation pulmonaire était prédominante (71 %). Seulement 32 % des enfants ont été diagnostiqués bactériologiquement en ayant recours à la microscopie (87%) et au tubage gastrique (50 %). Le gène Xpert n’a été utilisé que 11 fois et a décelé 2 cas de résistance. La radiographie pulmonaire a été réalisée chez 87 enfants avec 91% d’anomalies observées. La co-infection TB/VIH était de 24 %. A l’issue de la prise en charge, 71 % ont été adressés dans un centre spécialisé pour la poursuite de leur traitement, 16 % sont décédés et 8,5 % étaient perdus de vue. Le diagnostic de la TBI demeure donc complexe. La vulgarisation des techniques moléculaires peut en améliorer le diagnostic.Mots-clés: Tuberculose, enfant, diagnostic, AfriqueEnglish Title: Diagnostic and clinical aspects of childhood tuberculosis: about 94 cases collected in hospitals in Abidjan, Côte d'Ivoire, from 2015 to 2017English AbstractBackground Childhood TB (CTB) remains massively underreported. The main reason for underreporting is the difficulties with diagnosis. Early diagnosis and management of CTB thus remain a constant challenge to overcome. This was a retrospective chart review study of 94 children aged 0 to 14 diagnosed with Tuberculosis, conducted from 1st January 2015 to 31st December 2017 in 2 university hospitals. For the 94 records collected, the age group from 0 to 4 years was the most represented. The pulmonary localisation was predominant (71%). Only 32% of children were bacteriologically confirmed using microscopy (87%) and gastric aspiration (50%). The GeneXpert was used only 11 times and detected 2 resistance cases. Chest X-ray was performed in 87 children with 91% anomalies observed. The TB/HIV coinfection rate was 24%. At the completion of the treatment and care, 71% were referred to a specialized clinic for the continuation of their treatment and care, 16% died and 8.5% were lost to follow-up. Diagnosis of CTB remains challenging. The popularization of molecular techniques may improve its diagnosis.Keywords: Tuberculosis, child, diagnosis, Afric

Disclosure of HIV positive status : gender differences within the TEMPRANO trial participants, Côte d'Ivoire - ANRS 12239

For people living with HIV, disclosure of HIV status is an important challenge : informed friends or family members can be supportive, or on the contrary can stigmatise the HIV-positive person. We aimed to compare HIV status disclosure among men and women, since gender relationships create different opportunities and difficulties for both sexes. The study was conducted among HIV-positive adults enrolled in the TEMPRANO randomized trial in Côte d'Ivoire, which aims to compare very early antiretroviral treatment versus treatment initiation as per WHO current guidelines. All participants in this trial were asked questions on HIV status disclosure after 24 months of follow- up. Univariate and multivariate analyses were performed to compare disclosure patterns among men and women, disclosure to people living inside and/or outside the household, and in particular to the spouse or regular partner, and to identify the factors associated with disclosure. HIV status disclosure was frequent (more than 80%) among HIV patients, with no difference between men and women (p=0.45). For both, the regular partner was the most frequent confidant. But patterns of disclosure were different : men more frequently disclosed to a regular partner than women (74.1% vs 64.9%, p=0.004), because they were more likely to live with a regular partner (58.6% of men vs 35.8% of women). Men and women living with a regular partner reported similar levels of disclosure to the spouse (82.1% for men and 82.4% for women). Women disclosed more often than men to their children, siblings and mother. For both, the confidants were more often women (sisters, mother) than men (brothers, father). Our study shows that differences in the living conditions of men and women living with HIV and differences in gender roles induce gendered differences in HIV disclosure that should be considered in the care of the patient
