Nucleosides And Darunavir/Dolutegravir In Africa (NADIA): a Randomised Controlled Trial of Darunavir Versus Dolutegravir and Tenofovir Versus Zidovudine in Second-line Antiretroviral Therapy Regimens for the Public Health Approach in Sub-Saharan Africa

This trial evaluates options for second-line antiretroviral therapy in patients failing on a non-nucleoside reverse transcriptase inhibitor (NNRTI) and tenofovir (TDF)-based first-line regimen in the setting of the public health approach in sub-Saharan Africa (with assumed substantial nucleoside reverse transcriptase inhibitor (NRTI) cross-resistance). The trial tests two hypotheses. Firstly that a regimen of dolutegravir (DTG) with two NRTIs is non-inferior to a regimen of ritonavir-boosted darunavir (DRV/r) with two NRTIs. Secondly that continuing an NRTI regimen of TDF and lamivudine (3TC) is non-inferior to switching to zidovudine (ZDV) and 3TC.
The trial is a parallel group, open-label, multi-centre, factorial (2X2) randomised, controlled trial. Patients will be randomised to either DTG or DRV/r with a second randomisation to ZDV and 3TC or TDF and 3TC. Treatment efficacy will be monitored by testing viral load (VL). Analyses will compare DRV/r with DTG; and ZDV/3TC with TDF/3TC by intention to treat analysis on the primary outcome parameter of plasma VL below 400 copies/ml at 48 weeks. Trial follow-up will continue to 96 weeks.

Dual-ribavirin-imprinted composite membrane based on MOFs self-assembly design for selective separation studies

Author: Liu, Han ; Li, Yue ; Zhang, Zhaohan ; Wu, Yilin ; Wei, Maobin ; Diao, Zequan

Metal-organic frameworks (MOFs) possess several advantages, including high porosity, a large sp. surface area, tunable structures, and significant adsorption capabilities.However, traditional MOFs materials are vulnerable to the influence of small mols. or structural analogs of the target within complex systems, limiting their ability to selectively sep. specific mols.In this study, we integrated the imprinting technique with MOFs to create imprinted MOFs that exhibit enhanced selectivity and adsorption properties.A bottom-up approach, mediated by polydopamine (PDA), was employed as a linker to improve hydrophilicity and binding activity, thereby establishing a robust and stable adhesion platform for integrated structures.Subsequently, double imprinting was utilized to selectively isolate ribavirin (RBV).The secondary imprinting process involved constructing an imprinted layer of MOFs with specific recognition sites on the surface of a composite membrane, thereby generating specific imprinting sites.We investigated the adsorption isotherms and kinetics, along with permeation selectivity and stability, achieving a desirable rebinding capacity of 61.31 mg/g and permeation selectivity factors of β_ACV/RBV = 12.94, β_LAM/RBV = 14.81 and β_AZT/RBV = 16.91, resp.The water flux of the imprinted membranes produced using the suggested dual-imprinting technique was 16.12 times higher than that of monolayer imprinted membranes.The adsorption and selectivity of molecularly imprinted membranes (MIMs) can be greatly enhanced by the specialized recognition sites in the double-imprinted membranes interacting with RBV more efficiently due to its hydrophilia.This work provides new theor. and practical insights into addressing the critical scientific challenge of the 'trade-off' effect between permeation flux and permeation selectivity of template mols. during the osmotic separation process of conventional MIMs.

Inhibition of respiratory syncytial virus by Daclatasvir and its derivatives: synthesis of computational derivatives as a new drug development

Article

Author: Mitra, Debanjan ; Abdalla, Mohnad ; Afreen, Shagufta ; Das Mohapatra, Pradeep K.

The most common cause of respiratory tract illness in newborns and young children is the respiratory syncytial virus (RSV). There is no approved vaccination or specific antiviral medication for RSV infections. Here, an attempt has been made to explore the potential of currently marketed drugs as well as their probable derivatives to improve the possibility of developing stronger medications against RSV. From the 100 synthetic drug compounds library, the best drug molecule was identified through drug-likeness properties, toxicity, molecular docking and molecular dynamics simulations. Molecular Mechanics Generalized Born Surface Area (MM-GBSA) was also a method that was applied in this study. Daclatasvir showed the highest binding energy and appeared as the best drug to inhibit matrix protein and a fusion protein of RSV. Based on Daclatasvir, 40 computational derivatives were made. D28, D34 and D40 showed far better results than the actual drug. Changes in lipophilicity character increase the binding energy of derivatives. Molecular dynamic simulations showed their non-deviated, non-fluctuated and stable complex formation with target proteins. The high number of amino acid contacts throughout the trajectory increases the stability and effectiveness of derivatives. The key to producing a novel medicine to eradicate RSV is provided by derivatives. Daclatasvir will be employed as a potential RSV inhibitor up until that point.

Repurposing zidovudine and 5-fluoro-2′-deoxyuridine as antibiotic drugs made possible by synergy with both trimethoprim and the mitochondrial toxicity–reducing agent uridine

Article

Author: Cao, Sha ; Levenfors, Jolanta J ; Hughes, Diarmaid ; Bjerketorp, Joakim ; Guss, Bengt ; Öberg, Bo ; Broberg, Anders ; Nord, Christina

Abstract:

Objectives:

The increasing frequency of antibiotic-resistant bacterial infections is a major public health challenge, and new antibiotic drugs are urgently needed. A rapid solution to the problem is to repurpose clinically approved compounds with antibacterial properties, such as the nucleoside analogues zidovudine (azidothymidine) or 5-fluoro-2′-deoxyuridine. Here we report the in vitro and in vivo antibacterial properties of double and triple combinations of azidothymidine or 5-fluoro-2′-deoxyuridine with uridine and/or trimethoprim.

Methods:

We determined MICs of azidothymidine and 5-fluoro-2′-deoxyuridine, alone or combined with uridine and/or trimethoprim, against a selection of Gram-negative and Gram-positive bacteria. We also measured MICs of a selection of antibiotics of different classes as a function of uridine concentration. The efficacy of azidothymidine and 5-fluoro-2′-deoxyuridine with uridine and/or trimethoprim was measured in a murine peritonitis infection model.

Results:

The addition of uridine enhanced the in vitro antibacterial activity of azidothymidine and 5-fluoro-2′-deoxyuridine, against Gram-negative and Gram-positive bacteria, respectively. Uridine also enhanced the in vitro antibacterial activity of azidothymidine/trimethoprim and 5-fluoro-2′-deoxyuridine/trimethoprim combinations. Triple combinations containing azidothymidine, trimethoprim and uridine, showed antibacterial synergy against Gram-negative bacteria (Escherichia coli and Klebsiella pneumoniae) whereas the 5-fluoro-2′-deoxyuridine, trimethoprim and uridine combination showed synergy against the Gram-positive Staphylococcus aureus. The positive effect of uridine on the efficacy of azidothymidine/trimethoprim combination was also observed in vivo in a murine E. coli peritonitis model.

Conclusions:

Triple combinations of these clinically approved compounds warrant further investigations as therapies to combat antibiotic-resistant infections.

Abacavir Use Linked to Increased Incidence of MACE

THURSDAY, Aug. 8, 2024 -- For patients with HIV in the Randomized Trial to Prevent Vascular Events in HIV (REPRIEVE) trial, use of abacavir was associated with an increased incidence of major adverse cardiovascular events (MACE), according to a study presented at AIDS 2024, the 25th International AIDS Conference, held from July 22 to 26 in Munich. Carl J. Fichtenbaum, M.D., from the University of Cincinnati, and colleagues examined the role of prior and current use of antiretroviral agents (ART) on the development of MACE in a trial involving 7,769 participants aged 40 to 75 years on ART for at least 180 days. The median duration of ART use was 9.5 years, with variation by country. The researchers found that 22, 86, 49, and 47 percent of participants reported prior exposure to abacavir, tenofovir (TDF), thymidine analogs (AZT/d4T), and protease inhibitors (PIs), respectively. At study entry, 13, 61, 10, and 26 percent were using abacavir, TDF, AZT/d4T, and PIs, respectively. Entry regimens included two nucleoside reverse transcriptase inhibitors (NRTIs) plus a non-NRTI, integrase strand transfer inhibitor, or PI (47, 25, and 19 percent, respectively). Both former and current use of abacavir was associated with a higher incidence of MACE in adjusted analyses including the baseline regimen. No association was seen for former or current use of other ART agents with MACE. "Former and current use of abacavir was associated with a higher incidence of subsequent major adverse cardiovascular events in the REPRIEVE trial," the authors write.

Exploratory Analysis Associates HIV Drug Abacavir with Elevated Cardiovascular Disease Risk in Large Global Trial

July 23, 2024 -- Current or previous use of the antiretroviral drug (ARV) abacavir was associated with an elevated risk of major adverse cardiovascular events (MACE) in people with HIV, according to an exploratory analysis from a large international clinical trial primarily funded by the National Institutes of Health (NIH). There was no elevated MACE risk for the other antiretroviral drugs included in the analysis. The findings will be presented at the 2024 International AIDS Conference (AIDS 2024) in Munich, Germany. The Randomized Trial to Prevent Vascular Events in HIV (REPRIEVE) enrolled 7,769 study participants with HIV from 12 countries that found daily use of a cholesterol-fighting statin drug reduced the risk of major adverse cardiovascular events, such as heart attacks and strokes by more than one third. The REPRIEVE study team also performed statistical analyses to assess whether select ARVs were associated with MACE risk among study participants, all of whom had low-to-moderate cardiovascular disease risk. The ARVs selected for analysis had previously been linked to cardiovascular risk and included abacavir, tenofovir, zidovudine, stavudine, and drugs from a class called protease inhibitors (PIs). All were taken as part of multi-drug ART regimens. Overall, 22% of study participants reported prior exposure to abacavir, 86% to tenofovir, 49% to zidovudine or stavudine, and 47% to PIs. At study entry, 13% of participants were taking abacavir, 61% were taking tenofovir, 10% were taking zidovudine or stavudine, and 26% were taking PIs. In the investigators’ analyses, participants with prior and current use of abacavir had a 50% and 42% elevated risk of MACE, respectively, compared to participants with no abacavir exposure. Former or current use of other ARVs was not associated with any change in MACE risk, and the co-administration of common ARV drug classes as part of an ART regimen did not impact the elevated MACE risk among participants with current or prior abacavir exposure. According to the authors, these findings align with previous studies that also identified an elevated cardiovascular disease risk associated with abacavir. They suggest that more research is needed to better understand the increased risk observed in this analysis, including how these findings should be considered in the context of known cardiovascular disease risk factors, such as dyslipidemia, diabetes and hypertension, for people with HIV.
