Full textAlthough access to Antiretroviral therapy for Persons Living with HIV (PLHIV) in low income countries has been increasing, there still remain many challenges. In this framework our thesis carried in Cameroon was based on patient adherence to Antiretroviral Therapy (ART), HIV reistance to ART and decentralization of ART availability to district rural hospitals. We demonstrated that adherencemeasured using a face-te-face questionnaire (classical methode) does not correlate with the virological response when compared to plasma concentration measurement of medication. On the other hand our study of resistance of HIV to ART revealed a relatively low level of resistance (4,4% after 12 months and 16,9% after 24 months of treatment) in patients follow-up on a routine basis, that the WHO recommended second line ART regimens were efficient in almost all the patients (96%) with previous major resistance, and that the WHO recommended threshold for viral load to switch ART regimens in case of therapeutic failure in the absence of resistance test was adequate in 70% of cases. Finally, we observed that 1/4 of patients placed on ART based on WHO recommended criteria for decentralized zones had CD4 counts greater than 350 cells/ml

Full textDespite the efficient reduction of the HIV replication, the administration of combination antiretroviral therapy (c-ART) is not systematically accompanied by the restoration of the peripheral T CD4+ lymphocyte compartment. The life expectancy and quality are severely impacted in individuals with immunological failure. Together with peripheral abnormalities, an alteration of CD34+ hematopoietic progenitor may explain the frequency of the cytopenia observed in the latest stages of the disease. While a direct infection of CD34+ progenitors is thought to be extremely rare, quantitative studies performed in vitro have highlighted the impairment of the differentiation potential of these cells.We selected and matched individuals infected with HIV presenting extremely opposite immunological profile in response to c-ART as well as non-infected donors. The Immune Responders (IR) and Immune Non Responders (INR) treated since more than 8 years, presented similar characteristics for each parameter known to be involved in poor reconstitution of immune system. INR patients showed chronic immune activation, persistent inflammation and thymic regeneration failure. The frequency of circulating CD34 hematopoietic progenitors being not different between both groups of patients, we analyzed the differentiation potential of these cells at pre-thymic stages of lymphopoiesis.Using a co-culture system of hematopoietic progenitors with stromal cell lines OP9-DL1 (T-cell assay) or MS5 (B- and NK-cells assay) with appropriate cytokines, we highlighted an alteration of T-cell differentiation potential in INRs impacting their peripheral restoration. This was not observed in IRs who were similar to non-HIV donors. On the other hand, NK-cell differentiation potential was impaired in both groups of patients in comparison to non-HIV donors. Lastly, no abnormalities in B-cell potential were revealed.Studying molecular pathways involved in T-cell specification (Notch), proliferation (IL-7/IL7R) and survival (Fas/FasL, TNFR, caspase-1, P2X7) we observed the decreased viability of hematopoietic progenitors in HIV patients with increased caspase-1 activation involved in cellular death by pyroptosis. Moreover, expression of some Notch target genes was clearly Notch-independent. However, differences in transcriptional profile of BCL11B between IRs and INRs allowed us to postulate that T-cell differentiation is promoted over NK-cell differentiation in IR patients. Finally, CD34+ cells from INRs presented P2X7 overexpression (extracellular ATP receptor) and absence of CD73 ectonucleotidase (ATP hydrolysis) pointing out their increased susceptibility to extracellular nucleotides.Taken together our data, we postulate that highly inflammatory microenvironment of hematopoietic progenitor’s bone marrow niche disturbs their survival and differentiation in HIV patients. Thus, increased cellular death of CD34+ cells and probably neighboring cells amplifies the local inflammation. This is compensated in some patients by enhanced T-cell differentiation of CD34+ progenitors and results in immunological success. When it is not the case, the alteration of lymphopoiesis is important and the absence of reconstitution of peripheral T CD4+ lymphocyte compartment is noted. We believe have identified the population of HIV-infected individuals who will benefit from occasional administration of anti-inflammatory drugs (such as P2X7 antagonists)

Full textIntroduction: Since 2015, the WHO recommends to start antiretroviral treatment promptly in all HIV-infected children in order to reduce HIV related mortality. Despite increasing availability of screening tests and antiretroviral drugs, early initiation of antiretroviral treatment (ART) remains challenging in resource-limited countries. The ANRS 12140-Pediacam study assesses feasibility, effectiveness and tolerability in routine practice of early treatment of HIV-infected children in Cameroon. Objectives: The objectives of this thesis are to study mortality and virologic response at 2 and 4 years of early initiation of ART in HIV-infected infants and identify factors associated with virologic success. Methods: The analysis concerned the 190 HIV-infected infants who have initiated ART no later than 1 year (median=4 months) and were enrolled in the 3 Cameroon clinical sites involved in the PEDIACAM prospective cohort study since 2007. The first study evaluated adherence criterium based on the number of missed doses as reported through an adherence questionnaire in oerder to detect virologic failure in infants. The second study concerned the evaluation of the frequency and the factors associated with virologic success and mortality at 2 years of ART initiation, using competing risk regression. The third study concerned the evolution of virologic response between 2 and 4 years of QRT initiation depending on virologic status achieved at 2 years of ART initiation. Results: The performances of adherence questionnaire administered to the infant's caregiver are limited; the positive predictive value is low for detecting virologic failure in the absence of viral load exam. The mortality is high at 1 year after early ART initiation (18.0% [95% CI: 13.0 – 24.0]). The mortality is 3.3% [95%CI: 0.4 – 6.2] between 2 and 4 years of ART initiation. The probability of achieving at least once virologic success within the first 2 years of ART is around 80.0% but the probability of maintaining virologic success for at least 6 months was 67% for threshold=1000 copies/mL and 60% for threshold=400 copies/mL. At 4 years of ART initiation, the proportion of virologic success (viral load<400 copies/mL) is 75.2% [68.3-82.1]) in the 144 children still alive among whom viral load exam was not performed. The only factor associated with virologic success at 2 years of ART initiation is good adherence as reported by the caregiver. Et seuls un succès virologique obtenu à 2 ans et l’initiation plus récente du traitement antirétroviral sont associés à un charge virale contrôlée à 4 ans.Conclusion: Although the interest of early ART in HIV-infected infants is demonstrated, the mid and long term virologic success pass through strategies enhancing supporting steady and daily administration of drugs and regular monitoring of virologic response. The steady evaluation of adherence as reported by questionnaire has a very low performance for early detecting virologic failure. It is urgent to widely get access to routine viral load exam in resource-limited countries for quickly detecting virologic failures in children receiving antiretroviral treatment

Full textThe aim of our work was to study the mechanisms for HIV persistance in patients on long-term and effective HAART. During long-term HAART, HIV persists latently in a small pool of resting long-lived CD4 T cells. This invariably leads to rebound viral replication when HAART is discontinued and represents a major barrier to curing the infection. Here we examined the place of quiescent CD25hi FoxP3⁺ regulatory CD4 T cells (Tregs) in this latent reservoir Even after 8 years of effective HAART, we found latently infected Tregs with integrated replication-competent virus. Regardless of the time on HAART, latently infected cells appear more abundant in the Treg subset than in non-Tregs. This may be related to Treg features such as hyporesponsiveness and inhibition of cytotoxic T lymphocyte-related functions upon activation. The estimated half-life of the Treg and non-Treg reservoirs was similar, at 20 and 23 months respectively. We have demonstrated in vitro the effectiveness of the Histone deacetylase inhibitors in inducing viral expression in quiescent Tregs without full cell activation, making them accessible to CTL In this work, we also demonstrated that double LTR episomal HIV DNA was not stable and should be considered as potential markers of residual HIV replication during HAART

Full textAbsence of detectable HIV viremia treatment cessation in 3 children suggests that very early could lead to functional cure. The main objective is to qualitatively and quantitatively characterize viral reservoir and anti-HIV-1 antibodies virologically suppressed children in order to identify factors associated with their decrease. This is a prospective cross-sectional study included 97 children at the Gabriel Touré University Hospital (Bamako, Mali). They had a median age of 9.8 years at time of inclusion and 3.3 years at treatment initiation with a median HAART duration of 5.4 years. The median total HIV-DNA level was 445 copies/106 PBMCs, the median anti-gp41 antibodies activity was 0.29 optical density and the median HIV antibody level was 14.1 S/CO. We showed a high prevalence of HIV-1 resistance in HIV-DNA. Eight seroreversions were identified. A low anti-gp41 antibody activity was associated with both a younger age at HAART initiation and a lower level of anti-HIV antibodies. A lower anti-HIV antibodies level was associated with a younger age at HAART initiation. A significant proportion of virologically suppressed VHIV children who initiated HAART before the age of 2 years stopped to produce and/or progressively lost the HIV antibodies

Full textThe use of protease inhibitors (PIs) or non-nucleoside inhibitors (NNRTIs), appeared to protect specifically against acquired immunodeficiency disease syndrome dementia complex, suggesting that, in this condition, therapy might have a direct, additive effect in the central nervous system (CNS). However, several evidences suggest that these drugs and more particularly PIs are limited CNS or cerebrospinal fluid penetration due to the presence of efflux proteins like ABC multidrug transporters (P-gp, MRPs, BCRP) at level of the BBB and epithelial plexus choroïde. Evidence from in vitro and in vivo experiments has failed to resolve whether ARV CNS penetration and cerebrospinal fluid virologic suppression are clinically important. Using a new analytical method and a new in vitro human BBB model, we demonstrated the involvement of P-gp, BCRP and CYP3A4 in a limited passage of APV, EFV and NFV through the BBB

Full textVirologic failure, defined as a persistent detectable viremia under antiretroviral therapy, is mainly driven by the emergence of antiretroviral Drug Resistance-Associated Mutations (DRAM) in the target genes of antiretroviral drugs. Identifying these mutations usually requires viremia above 1000 copies/mL, explaining why resistance data in persistent HIV-1 low-level viremia (LLV) (< 1000 copies / ml) are scarce in spite of the fact that this clinical situation concerns 5 to 10 % of treated HIV-infected individuals. In this work, we studied DRAM in 3 cohorts of HIV-1 infected patients, who experienced LLV (< 500 to 1000 copies/ml) under antirétroviral therapy, and then attempted to identify clinical and virologic factors associated to their emergence. For patients receiving first-line antiretroviral therapy, new DRAM are detected during LLV in 37% subjects, all in the reverse transcriptase gene except in the protease gene in one participant, and detection of new DRAM is associated with higher HIV-1 RNA levels during LLV. Integrase inhibitors resistance-associated mutations are newly detected in 7,7 % of pretreated patients with multi-resistant virus strains who experienced LLV while receiving raltegravir-containing therapy, with no factors significantly associated with their emergence identified. Finally in a third cohort of patients, heterogeneous according to their antiretroviral history and their viral population, new DRAM are detected in 30 % of subjects for both reverse transcriptase, protease and integrase inhibitors, without any factor associated to their emergence. So, new DRAM can be detected during LLV under antiretroviral therapy, whereas their type and their frequency vary according to the current antiretroviral regimen and the previous archived viral mutations. These data underline the potential interest of drug résistance genotyping in this setting, in order to be able to provide an early therapeutic optimization, the utility of which should be assessed in the future

Full textIn 2010, the World Health Organization (WHO) published new HIV/AIDS treatment recommendations which aim at improving the quality of antiretroviral therapy (ART) delivered in developing countries. Nonetheless, the higher costs of incorporating new and more potent antiretrovirals (ARVs), coupled by the intensification of intellectual property rights (IPRs) protection, put in evidence a growing trade-off between patient coverage expansion priorities and treatment quality objectives, which tend to favor the perpetuation of a double standard of HIV care in the world.This thesis aims at analyzing the determinants of technology incorporation and price evolution in HIV care as the basis for discussing how these can impact both the quality and affordability of ART in low and middle-income settings. The present research takes as reference the Brazilian ART policy and the insights it may provide in the fight against the HIV/AIDS epidemic. The first part of this thesis addresses the criteria used for the incorporation of novel drugs in ART guidelines. Content and statistical analyses are used to examine the impact of ARV prices on therapeutic recommendations and how the latter have been able to influence clinical practice. They show that, although efficacy, toxicity and dosing convenience represent major determinants of ART incorporation decisions in Brazil, costs have most recently started influencing deferral in the use of new ARVs. The second part takes into account the role of patent protection on pharmaceutical innovation and pricing, further employing descriptive and econometric approaches to analyze ARV market structure and prices in Brazil
