Full textHIV infection remains a major public health concern, especially in sub-Saharan Africa. Scaling up antiretroviral treatment is a major challenge, and requires a genuine cascade of care, i.e. a continuum between infection, diagnosis, care, clinical and laboratory follow-up and achievement of an undetectable viral load – the proxy for infection control -. Decentralization of programs is a prerequisite to widen access to this continuum of care. In this thesis, we will explore some of the pitfalls encountered in the context of decentralization of antiretroviral treatment, through the analysis of data retrieved from 2006 to 2013 in studies performed in the Center Region of Cameroon. In a first article, the impact of task shifting from doctors to nurses is assessed using data from the cohort of patients followed in the nine rural district hospitals of the Stratall trial. Our analysis shows that this solution to address the shortage of physicians preserves the clinical and biological outcomes of patients in the first two years of antiretroviral treatment. In a second article, the accuracy of several criteria for identifying treatment failure is assessed for predicting the onset of HIV drug resistance. Notwithstanding the difficulties of deploying biological monitoring tools, our results highlight the importance of evaluating viral load to predict the emergence of resistance, and particularly rapid re-testing after the first notion of detectability to switch patients to second line in a timely manner. The third part of the thesis handles individual issues, and more specifically the gender issue. Our results show that men and women followed in decentralized areas reach similar levels of adherence, but that men's vulnerability under treatment - especially through higher failure rate- is independent of adherence. Finally, the fourth part focuses on routine care provided in the District Hospital of Mfou, Cameroon. Our results add to the growing body of evidence to enable the formulation of public health recommendations on task shifting and definition of treatment failure. They also raise research perspectives as they impair the paradigm of adherence to explain a difference in treatment efficiency between men and women

Full textOne of the major barriers to the optimal care of patients undergoing antiretroviral therapy is the limited access to viral load (VL) and genotyping tests, especially in remote areas. These technologies are usually available only at central health facilities in larger cities and plasma is the reference sample. However, plasma or whole blood samples shipment from remote areas to reference lab faces several constraints or even impossible. In order to bring closer patients to reference lab, we have demonstrated the ability of DBS (Dried Blood Spots) collected and shipped in field conditions to provide complete virological monitoring (VL and genotyping). We also documented for the first time, virological outcome of ART and HIV-1 genetic diversity in adult patients followed up in decentralized settings in Senegal, Mali and Guinea Conakry. Overall, despite the low treatment adherence noted sometimes, our findings show no significant differences in the occurrence of virological failure among patients followed up in the central and peripheral health facilities, whatever the country. In Senegal, no integrase inhibitors associated DRM has been found despite the high rate of resistance in patients failing first and second-line treatment. Furthermore, among children born to HIV infected mothers, NNRTI-associated drug resistant mutations (DRM) were more predominant, probably because of systematic use of Nevirapine in MTCT. Our studies also confirm the high genetic diversity of viral subtypes, with the dominance of CRF02_AG in West Africa. This work presented here highlights the feasibility and relevance of DBS as support for the virological monitoring of patients in decentralized settings in West Africa. Furthermore, its use showed high rate of virological failure indicating the need to reinforce adherence to treatment. Finally, our results highlight the utility to considering carefully drug resistance patterns before switching to another ART regimen

Full textThe world health organization (WHO) recommendation updates regarding care of HIV-infected children reflects new scientific findings in clinical trials. Their implementation in routine practice, especially in resource-limited countries, should consider local operational constraints in order to direct good clinical practice guidelines. We put in place this work in order to evaluate the early care process of HIV-exposed infants aged less than 7 months including: early diagnosis of HIV, initiation of antiretroviral therapy (ART), and immune responses to vaccines administered by the Expanded Program on Immunization (EPI). Our data were collected from two surveys: the current ANRS-PEDIACAM cohort which started in 2007, in three urban hospitals located in Cameroon, and the ACIP-EPIPEV cross sectional study conducted from November 2004 to May 2005, in five urban hospitals based in Cameroon and the Central African Republic. Our results strongly suggested that both early HIV diagnosis and initiation of ART in infants were feasible and well accepted in “real pediatric world urban settings”. Among HIV-exposed infants enrolled in the PEDIACAM study, 89.7% were tested for HIV at a median age of 1.5 months and 83.9% completed the process by returning for the result before 7 months of age. Incomplete process was associated to factors related to the quality of antenatal care and obstetrical emergency than environmental ones. Among HIV-infected infants identified, 83.5% started ART before 7 months of age. However, ART initiation was considered as suboptimal in approximately one third of them. Risk factors associated with this delay were related to the care delivery system, including delays in sample collection and turn around procedures. Finally, the EPIPEV study showed that antibody levels to EPI vaccines in HIV-uninfected children born to HIV-infected mothers were higher compared to levels in HIV-infected children (60% vs 20% concerning measles vaccine), but lower than the levels described for children born to HIV-uninfected mothers. This result suggested an immunological dysfunction of HIV-exposed children which occurred during pregnancy and could affect their survival. Overall, our studies contributed in providing findings that could help in improving early care in HIV-exposed infants. These include the structural and functional organization of health structures, the effective implementation of current recommendations, and of active coordination

Full textHIV-1 group O (HIV-1/O) is genetically distinct from HIV-1/M and is endemic in Cameroon while in France 140 HIV-1/O were diagnoses since 1990. The aim of this work was to characterize HIV-1/O epidemiological characteristics, infection natural evolution and immuno-virological response to treatment.In France, based on a large series of 101 HIV-1/O patients, we demonstrated that the natural evolution of HIV-1/O was in between the evolution of HIV-2 and HIV-1/M, but closer to HIV-1/M. We also confirmed in vivo HIV-1/O natural resistance to INNTI treatment. Then, we compared HIV-1/O and HIV-1/M immune-virological response to ARV treatment. In France, we compared data from two cohorts and a clinical trial was performed in Cameroun. One of the HIV-1/O characteristic is the lower CVp before treatment compared to HIV-1/M in naïve patient. This difference had no impact on the virological responses to cART. The proportion of patients with an undetectable pVL was similar between the two groups one year after the beginning of the treatment. Immunological response was close between HIV-1/O and HIV-1/M in France. But when the two populations were compared in Cameroon, the immunological response to cART was lower for HIV-1/O patients than for HIV-1/M patients, although this diffence didn’t had clinical consequences.HIV-1/O medical care based on HIV-1/M guidelines is highly efficient if the treatment doesn’t include NNRTI treatment

Full textRetroviral replication of HIV-1 requires host-encoded tRNALys3 for priming reverse transcription. In order to inhibit transcription, the strategy aims to prevent recognition between tRNALys3 and viral RNA by targeting tRNALys3 with small molecules. TRNALys3 ligands have been synthesized by a fragment-based approach. Interactions of these ligands to tRNA were studied by NMR and fluorescence spectroscopy. Development of these ligands was made from two molecules identified in a NMR primary screening: kynuramine and diaminocyclopentanol. These fragments bind with millimolar affinity to different sites within the tRNA. Simple structural changes were first made on kynuramine. The fragments were then linked by aminoester and triazole groups. Finally, diaminocyclopentanol dimers were developed by incorporating aromatic groups

Full textDespite the success of antiretroviral treatment (ART), chronic infection with human immunodeficiency virus type 1 (HIV-1) associates with various immune defects. The combination of immunotherapies with ART may be a promising strategy to modulate low-grade inflammation, and/or exhaustion. The development of a preclinical model is required to evaluate the efficacy of therapies targeting the PD1-PDL1 pathway. In this work, we used the Balb/c Rag2KO IL2rγcKO SirpαNOD Flk2KO HLA-A2HHD (BRGSF-A2) humanized immune system (HIS) mouse model.We confirmed the physiological development of the human T cell compartment in this model, and observed similar exhaustion (PD1, TIGIT) and senescence (CD57) profiles on T cells in HIS mice, as those observed in humans. We next developed an HIS model of controlled infection induced by tritherapy and evaluated the impact of therapies targeting the PD1/PD-L1 pathway. In a model of ART interruption, we did not observe any major effects of αPD1 blockage induced prior to ART treatment interruption. This result may be related to the absence of modulation of PD1 expression on T cells during infection or ART treatment. On the contrary, we observed changes in the proportion of PD-L1⁺ T cells in the acute phase of the infection, and also during ART treatment. The addition of αJAK reinforced the reduction in the proportion of PD-L1⁺ T cells, already observed upon ART treatment.Targeting the IFN-I signaling pathway appears to modulate both inflammation and exhaustion. It may represent a valuable strategy to improve immune responses during chronic controlled HIV-1 infection
