In a previous trial of antiretroviral therapy (ART) involving pregnant women with human immunodeficiency virus (HIV) infection, those randomly assigned to receive tenofovir, emtricitabine, and ritonavir-boosted lopinavir (TDF-FTC-LPV/r) had infants at greater risk for very premature birth and death within 14 days after delivery than those assigned to receive zidovudine, lamivudine, and ritonavir-boosted lopinavir (ZDV-3TC-LPV/r).
To estimate the long-term metabolic effects of initiating a lopinavir/ritonavir (LPV/r)-based regimen as first-line therapy for HIV-infected children less than three years of age in resource-limited settings.
The QoLKAMON study evaluated quality of life, efficacy and treatment safety in HIV patients receiving lopinavir/ritonavir in monotherapy (MT) versus continuing combined antiretroviral triple treatment with a boosted protease inhibitor (TT).
The goal of this study is to profile the metabolic changes in the plasma of HIV patients receiving lopinavir/ritonavir (LPV/r)-based highly active antiretroviral therapy (HAART) relative to their treatment-naïve phase, aimed to identify precision therapy for HIV for improving prognosis and predicting dyslipidemia caused by LPV/r.
Ritonavir and Lopinavir have previously been demonstrated to decrease the maximum solubility advantage and flux in the presence of each other. The present study investigated the ability of Ritonavir and Lopinavir co-amorphous materials to generate a supersaturated state. Further, it explored the precipitation and flux behavior of co-amorphous materials. The co-amorphous materials of Ritonavir and Lopinavir were prepared by quench cool method and characterized in the solid state using XRPD, DSC, FTIR. The so...
To evaluate changes in pro-atherosclerotic biomarkers and endothelial function in patients initiating two different PI-based regimens as part of ART.
The OPTIPRIM-ANRS 147 trial compared intensive combination ART (darunavir/ritonavir, tenofovir disoproxil fumarate/emtricitabine, raltegravir and maraviroc) started early during primary HIV-1 infection with standard tritherapy with darunavir/ritonavir, tenofovir disoproxil fumarate and emtricitabine. From month 6 to 18, the percentage of viral load values
Abacavir has replaced stavudine in antiretroviral therapy (ART) regimens because it has largely been phased out as a result of toxicity concerns; this loss has reduced further the already-limited drug options for children. Few data regarding virologic and metabolic outcomes among children who undergo substitution of stavudine exist. We evaluated the effects of preemptive substitution of abacavir for stavudine in children initially without lipodystrophy and virally suppressed on a stavudine-containing regime...
Sparing of antiretroviral drug classes could reduce the toxicity and cost of maintenance treatment for HIV infection.
The integrase inhibitor regimen (elvitegravir [EVG]/cobicistat [COBI]/emtricitabine [FTC]/tenofovir disoproxil fumarate [TDF]) demonstrated superior efficacy when compared to a protease inhibitor regimen (ritonavir-boosted atazanavir [ATV+RTV] plus FTC/TDF) in 575 treatment-naïve women at week 48. We investigated the efficacy, safety, and tolerability of switching to a TAF-based, single-tablet regimen containing EVG, COBI, FTC, and tenofovir alafenamide TAF (E/C/F/TAF) versus remaining on ATV+RTV and FTC/T...
Resource constraints in low and middle-income countries necessitate practical approaches to optimizing antiretroviral therapy outcomes. We hypothesised that an untimed plasma lopinavir concentration (UPLC) at week 12 would predict loss of virological response in those taking lopinavir as part of a second-line antiretroviral regimen.
Identification of Highly Potent Human Immunodeficiency Virus Type-1 Protease Inhibitors against Lopinavir and Darunavir Resistant Viruses from Allophenylnorstatine-Based Peptidomimetics with P2 Tetrahydrofuranylglycine.
The emergence of drug-resistant HIV from a wide-spread anti-viral chemotherapy targeting HIV protease in the past decades is unavoidable and provides a challenge to develop alternative inhibitors. We synthesized a series of allophenylnorstatine-based peptidomimetics with various P3, P2 and P2´ moieties. The derivatives with P2 tetrahydrofuranylglycine (Thfg) were found to be potent against wild type HIV-1 protease and the virus, leading to a highly potent compound 21f (KNI-1657) against lopinavir/ritonavir...
Following widespread use of stavudine, a thymidine analogue, in antiretroviral therapy (ART) over the past three decades, up to a third of children developed lipoatrophy (LA) and/or lipohypertrophy (LH). Following phasing-out of stavudine, incidence of newly-diagnosed LA and LH declined dramatically. However, the natural history of existing cases should be explored, particularly with prolonged protease inhibitor exposure.
The present study evaluated the placental transfer and amniotic fluid distribution of bupivacaine enantiomers in health pregnant women and in HIV-infected pregnant women receiving epidural anaesthesia for caesarean section.
To investigate the long-term safety and efficacy of a treatment switch to dual ART with atazanavir/ritonavir + lamivudine versus continuing a standard regimen with atazanavir/ritonavir + 2NRTI in virologically suppressed patients.
To characterize a drug-combination nanoparticle (DcNP) containing water-insoluble lopinavir (LPV) and efavirenz (EFV), and water-soluble tenofovir (TFV), for its potential as a long-acting combination HIV treatment.
Pharmacokinetic modelling of darunavir/ritonavir dose reduction (800/100 to 400/100 mg once daily) in a darunavir/ritonavir-containing regimen in virologically suppressed HIV-infected patients: ANRS 165 DARULIGHT sub-study.
In the ANRS 165 DARULIGHT study (NCT02384967) carried out in HIV-infected patients, the use of a darunavir/ritonavir-containing regimen with a switch to a reduced dose of darunavir maintained virological efficacy (≤50 copies/mL) for 48 weeks with a good safety profile.
Ritonavir is one of several ketoconazole alternatives used to evaluate strong CYP3A4 inhibition potential in clinical drug-drug interaction (DDI) studies. In this study, four physiologically-based pharmacokinetic (PBPK) models of ritonavir as an in vivo time-dependent inhibitor of CYP3A4 were created and verified for the oral doses of 20, 50, 100 and 200 mg using fraction absorbed (Fa) and oral clearance (CLoral) values reported in the literature, as transporter and CYP enzyme reaction phenotyping data were...
The concentration of antiretroviral drugs in wastewater treatment plants (WWTP) effluents and surface waters of many countries has increased significantly due to their widespread use for HIV treatment. In this study, the removal of stavudine and zidovudine under UV254 photolysis or UV254/H2O2 was investigated in a microcapillary film (MCF) photoreactor, using minimal water samples quantities. The UV254 quantum yield of zidovudine, (2.357 ± 0.0589)·10-2 mol ein-1 (pH 4.0-8.0), was 28-fold higher th...
To report a case involving a patient with presumed panretinal ritonavir-induced retinopathy.
To assess whether low-dose ritonavir-boosted darunavir (darunavir/r) in combination with two NRTIs could maintain virological suppression in patients on a standard regimen of darunavir/r + two NRTIs.
In April 2010 tenofovir and abacavir replaced stavudine in public-sector first-line antiretroviral therapy (ART) for children under 20 years old in South Africa. The association of both abacavir and tenofovir with fewer side-effects and toxicities compared to stavudine could translate to increased durability of tenofovir or abacavir-based regimens. We evaluated changes over time in regimen durability for pediatric patients 3 to 19 years of age at 8 public sector clinics in Johannesburg, South Africa.
To analyse lipid changes and tolerability in a cohort of HIV-infected patients who switched their antiretroviral regimens to rilpivirine/emtricitabine/tenofovir (RPV/FTC/TDF) in a real-world setting.
In an era when virological efficacy approaches 100%, novel antiretroviral (ARV) therapies must deliver better tolerability, safety, and convenient coformulated regimens. We review the phase II and III clinical data on the fixed dose combination (FDC) darunavir (DRV) 800mg / cobicistat (COBI/C) 150 mg / emtricitabine (F/FTC) 200 mg / tenofovir alafenamide fumarate (TAF) 10mg (D/C/F/TAF) for the treatment of HIV-1 infection.
Paritaprevir/ritonavir/ombitasvir and dasabuvir with or without ribavirin for 12 weeks is approved for treatment of chronic HCV genotype 1 infection. This study assessed the efficacy of shortened duration paritaprevir/ritonavir/ombitasvir and dasabuvir with or without ribavirin for eight weeks among people with recent HCV infection. In this open-label single-arm trial conducted in Australia, England and New Zealand, adults with recent HCV (duration of infection
