LES LYMPHOMES B NON-HODGKINIENS FONT PARTIE DES RARES TUMEURS A EXPRIMER DES MOLECULES HLA DE CLASSE II. CECI LEUR PERMET D'INTERAGIR DIRECTEMENT AVEC LES LYMPHOCYTES T CD4+ QUI INFILTRENT LA TUMEUR (TIL-T). LA SIGNALISATION INDUITE PAR LES MOLECULES HLA-DR PEUT INDUIRE SOIT L'APOPTOSE, SOIT LA PROLIFERATION. LA PREMIERE PARTIE DE CE TRAVAIL A ETE D'ETUDIER LE ROLE JOUE PAR LES MOLECULES HLA DE CLASSE II DANS L'INTERACTION ENTRE LES TIL-T CD4+ ET LES LYMPHOCYTES B MALINS DE LYMPHOME FOLLICULAIRE. PAR L'INTERMEDIAIRE DES MOLECULES HLA DE CLASSE II, DES CLONES DE TIL-T CD4+ SONT CAPABLES D'INDUIRE L'ACTIVATION DES LYMPHOCYTES B MALINS ET LEUR ENTREE EN PHASE G1 DU CYCLE CELLULAIRE (INDUCTION DU KI-67). AFIN DE DETERMINER SI LES LYMPHOCYTES B MALINS PRESENTENT DES ANOMALIES INTRINSEQUES LES EMPECHANT DE PROGRESSER DANS LE CYCLE CELLULAIRE, NOUS AVONS ETUDIE DANS UNE DEUXIEME PARTIE L'EFFET D'UNE SIGNALISATION INDUITE PAR LES MOLECULES HLA-DR DANS DES LYMPHOCYTES B NORMAUX. NOUS AVONS D'ABORD MONTRE QUE L'ORIENTATION VERS UNE VOIE APOPTOTIQUE OU PROLIFERATIVE NE DEPEND PAS DE L'ETAT D'ACTIVATION DU LYMPHOCYTE B, MAIS DE LA CAPACITE DU LIGAND A REGROUPER LES MOLECULES HLA-DR A LA SURFACE DE LA CELLULE. EN EFFET, UN AC ANTI-HLA-DR COUPLE A DES BILLES DE SEPHAROSE (QUI MIME LA RELATION AVEC UN LYMPHOCYTE T CD4+) INDUIT LA PROLIFERATION DES LYMPHOCYTES B NORMAUX ALORS QU'UN AC ANTI-HLA-DR COUPLE A UN AC SECONDAIRE, INDUIT L'APOPTOSE, SANS ENTREE PREALABLE DANS LE CYCLE CELLULAIRE. CES RESULTATS MONTRENT QUE DANS LES LYMPHOCYTES B TUMORAUX, L'ENTREE EN CYCLE CORRESPOND BIEN A UN DEBUT DE PROLIFERATION ET NON A UN PRELUDE A L'APOPTOSE. NOUS AVONS REPLACE LA SIGNALISATION HLA-DR DANS UN CONTEXTE PHYSIOLOGIQUE : LES LYMPHOCYTES B RECOIVENT D'ABORD UN SIGNAL INDUIT PAR L'INTERACTION D'UN ANTIGENE SUR LE RECEPTEUR A L'AG DU LYMPHOCYTE B, CE QUI INDUIT UNE PROLIFERATION. ENSUITE, ILS INTERAGISSENT AVEC DES LYMPHOCYTES T CD4+, ENTRAINANT UNE SIGNALISATION PAR LES MOLECULES HLA-DR DANS LE LYMPHOCYTE B. LA PROLIFERATION INDUITE PAR LA STIMULATION DU RECEPTEUR A L'AG EST REGULEE NEGATIVEMENT PAR CO-STIMULATION AVEC UN AC ANTI-HLA-DR LIE A UN AC SECONDAIRE. CECI SE TRADUIT AU NIVEAU DU CYCLE CELLULAIRE, PAR UNE DIMINUTION DE LA PHOSPHORYLATION DE LA PROTEINE PRB DUE A UNE DIMINUTION D'EXPRESSION DES CDK2, 4 ET 6 ET DES CYCLINES E ET A, ET A UN RETARD D'EXPRESSION DE LA CYCLINE D2. LES CDKIS P21 ET P27 NE SONT PAS IMPLIQUES. NOS RESULTATS MONTRENT QU'UN SIGNAL INDUIT PAR HLA-DR EST SUFFISANT POUR INDUIRE UNE PROLIFERATION. L'ABSENCE DE PROLIFERATION DANS LES LYMPHOCYTES B TUMORAUX SUGGERENT FORTEMENT LA PRESENCE D'UNE (OU PLUSIEURS) ANOMALIE(S) INTRINSEQUE(S) EMPECHANT LA PROGRESSION DANS LE CYCLE CELLULAIRE. CE BLOCAGE SEMBLE ETRE GENERAL PUISQU'IL N'AFFECTE PAS QUE LA VOIE HLA DE CLASSE II MAIS EGALEMENT LA VOIE IL4/CD40

Long-term efficacy and toxicity of abacavir/lamivudine/nevirapine compared to the most prescribed ARV regimens before 2013 in a French Nationwide Cohort Study( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Abstract : Abstract: Data on the long-term efficacy and safety of abacavir/lamivudine (ABC/3TC) and nevirapine (NVP) are scarce. This combination has the advantage of simplifying treatment and improving long-term tolerance. The aim of this study was to compare the rate of any discontinuation of antiretroviral (ARV) regimen because of virologic failure (VF), and/or adverse drug reaction (ADR) among patients receiving stable ARV regimens for at least 6 months. ABC/3TC/NVP was compared to ABC/3TC with either ritonavir-boosted darunavir (DRV/r) or ritonavir-boosted atazanavir (ATV/r), unboosted ATV, or tenofovir/emtricitabine (TDF/FTC) with either one of the following: ATV/r, unboosted ATV, DRV/r, efavirenz (EFV), or NVP, in the French prospective multicenter Dat'AIDS cohort. The study enrolled 16, 511 patients treated with following ARV regimens: ABC/3TC/NVP (n = 1089), TDF/FTC/NVP (n = 1542), ABC/3TC/DRV/r (n = 1065), ABC/3TC/ATV/r (n = 1847), ABC/3TC/ATV (n = 563), TDF/FTC/ATV/r (n = 3519), TDF/FTC/DRV/r (n = 2767), TDF/FTC/ATV (n = 419), and TDF/FTC/EFV (n = 3700). Mean follow-up was 36 ± 24 months. Patients treated with ABC/3TC/NVP received this regimen as a switch regimen in 97% of cases. By multivariable analysis, the risk of treatment discontinuation due to VF was similar between ABC/3TC/NVP and other ARV regimens, except for TDF/FTC/ATV and ABC/3TC/ATV, which were associated with a higher risk of treatment interruption due to VF (hazard ratio [HR] 1.99; 95% confidence interval [CI] 1.29-3.06 and HR 2.19; 95% CI 1.51-3.18, respectively). Treatment discontinuation due to ADR was lowest with the ABC/3TC/NVP regimen. Other ARV regimens were associated with a 1.80- to 3.19-fold increase in the risk of treatment discontinuation due to ADR (P <0.0001 for all comparisons). ABC/3TC/NVP as a simplification regimen is a long-term effective regimen with lower discontinuation due to long-term toxicity compared with other standard ARV regimens

L'apport de l'évaluation pharmacocinétique dans le choix des antirétroviraux (nature et dose) chez la personne vivant avec le VIH by Minh Lê( )

Despite the recent advances in HIV therapy, antiretroviral (ARV) treatment remains for life in order to control the HIV infection. Thus, maintenance strategies, developed to decrease the chemical burden of ARV, are evaluated to enhance the long-term tolerance with a similar efficacy to standard triple therapy. Anatomical sanctuaries such as central nervous system or genital compartment are sites of HIV replication. The penetration of ARV, from the systemic compartment to the deep compartments, is essential to control the HIV infection in these sanctuaries. First, we assessed the penetration of maraviroc, raltegravir and rilpivirine in genital fluids (seminal and cervico-vaginal fluids) in standard triple therapy. We reported a good penetration of maraviroc and raltegravir and mild penetration of rilpivirine in both genital fluids. Then, in a second project, we evaluated the plasma exposure of darunavir/ritonavir in a reduced daily-dose of darunavir in the ANRS-165 DARULIGHT study and the seminal penetration at both dosing regimen. We reported a complex pharmacokinetic interaction between darunavir and ritonavir: no significant difference was observed in both plasma and seminal exposure of darunavir, despite the 50% decrease of darunavir daily-dose. These results highlight the absence of linearity of both darunavir and ritonavir plasma exposures in the explanation of the interaction mechanism. Finally, we assessed the plasma exposure and the seminal penetration of etravirine, raltegravir and its inactive glucuronide metabolite in the ANRS-163 ETRAL study. No metabolic interaction was expected between etravirine and raltegravir. Nevertheless, we reported a probable interaction through the efflux transporters which might impact the seminal penetration of raltegravir and its metabolite. To summarize, our results from the different projects allowed to precise the influence of blood and seminal (in a lesser extent) plasma proteins in the penetration or accumulation of ARV in the male genital tract and the probable role of efflux transporteurs. Our results from the different projects contribute to assess the seminal penetration of ARV in relation with the respective plasma protein binding but also the elimination half-life and the probable role of efflux transporters

Week 96 efficacy of lopinavir/ritonavir monotherapy in virologically suppressed patients with HIV: a randomized non-inferiority trial (ANRS 140 DREAM)( )

1 edition published in 2018 in English and held by 1 WorldCat member library worldwide

Abstract Background Sparing of antiretroviral drug classes could reduce the toxicity and cost of maintenance treatment for HIV infection. Objectives To evaluate the non-inferiority of efficacy and the safety of lopinavir/ritonavir (r) monotherapy versus a single-tablet regimen of efavirenz, emtricitabine and tenofovir (EFV/FTC/TDF) over 2 years. Methods Adults on stable ART with plasma HIV-1 RNA viral load <50 copies/mL for the past 12 months and no documented treatment failure were randomized to receive either lopinavir/r or EFV/FTC/TDF for 2 years. The primary endpoint was the proportion of patients without treatment failure at week 96 (viral load <50 copies/mL at week 96, confirmed at week 98), without study treatment discontinuation, a new AIDS-defining illness, or death. Results In the ITT analysis, the primary endpoint was reached by, respectively, 64% and 71% of patients in the lopinavir/r (n = 98) and EFV/FTC/TDF arms (n = 97), yielding a difference of -6.8% (lower limit of the 95% two-sided CI: -19.9%). Sanger and UltraDeep sequencing showed the occurrence of PI mutations in the lopinavir/r arm (n = 4) and of NNRTI and/or NRTI mutations in the EFV/FTC/TDF arm (n = 2). No unexpected serious clinical events occurred. Conclusions Lopinavir/r monotherapy cannot be considered non-inferior to EFV/FTC/TDF. PI resistance rarely emerged in the lopinavir/r arm and did not undermine future PI options. Two years of lopinavir/r monotherapy had no deleterious clinical impact when compared with EFV/FTC/TDF

Lung Cancer Screening with Chest Computed Tomography in People Living with HIV: A Review by the Multidisciplinary CANCERVIH Working Group( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

ABSTRACT : N/A: A shift in mortality and morbidity has been observed in people living with human immunodeficiency virus (PLWHIV) from acquired immunodeficiency syndrome (AIDS) to non-AIDS diseases. Lung cancer has the highest incidence rates among all the non-AIDS-defining malignancies and is associated with mortality rates that exceed those of other cancers. Strategies to increase lung cancer survival in PLWHIV are needed. Lung cancer screening with chest LDCT has been shown to be efficient in the general population at risk. The objective of this review is to discuss lung cancer screening with chest computed tomography in PLWHIV. Lung cancer screening in PLWHIV is feasible. Whether PLWHIV could benefit from an age threshold for screening that is earlier than the minimum age of 55 years usually required in the general population still needs further investigation. Studies evaluating smoking cessation programs and how they could be articulated with lung cancer screening programs are also needed in PLWHIV
