Abstract
BACKGROUND Appropriate interactions between antiretroviral therapies (ART) and drug transporters and metabolizing enzymes at the blood brain barrier (BBB) are critical to ensure adequate dosing of the brain to achieve HIV suppression. These proteins are modulated by demographic and lifestyle factors, including substance use. While understudied, illicit substances share drug transport and metabolism pathways with ART, increasing the potential for adverse drug:drug interactions. This is particularly important when considering the brain as it is relatively undertreated compared to peripheral organs and is vulnerable to substance use-mediated damage. METHODS We used an in vitro model of the human BBB to determine the extravasation of three first-line ART drugs, emtricitabine (FTC), tenofovir (TFV), and dolutegravir (DTG), in the presence and absence of cocaine, which served as our illicit substance model. The impact of cocaine on BBB integrity and permeability, drug transporters, metabolizing enzymes, and their master transcriptional regulators were evaluated to determine the mechanisms by which substance use impacted ART central nervous system (CNS) availability. RESULTS We determined that cocaine had a selective impact on ART extravasation, where it increased FTC's ability to cross the BBB while decreasing TFV. DTG concentrations that passed the BBB were below quantifiable limits. Interestingly, the potent neuroinflammatory modulator, lipopolysaccharide, had no effect on ART transport, suggesting a specificity for cocaine. Unexpectedly, cocaine did not breach the BBB, as permeability to albumin and 4 kDa FITC-dextran, as well as tight junction proteins and adhesion molecules remained unchanged. Rather, cocaine selectively decreased the pregnane-x receptor (PXR), but not constitutive androstane receptor (CAR). Consequently, drug transporter expression and activity decreased in endothelial cells of the BBB, including p-glycoprotein (P-gp), breast cancer resistance protein (BCRP), and multidrug resistance-associated protein 4 (MRP4). Further, cytochrome P450 3A4 (CYP3A4) enzymatic activity increased following cocaine treatment that coincided with decreased expression. Finally, cocaine modulated adenylate kinases that are required to facilitate biotransformation of ART prodrugs to their phosphorylated, pharmacologically active counterparts. CONCLUSION Our findings indicate that additional considerations are needed in CNS HIV treatment strategies for people who use cocaine, as it may limit ART efficacy through regulation of drug transport and metabolizing pathways at the BBB.

Comparison of Virological Efficacy of DTG/ABC/3TG and B/F/TAF Regimens and Discontinuation Patterns in Persons Living with Advanced HIV in the Era of Rapid ART: A Retrospective Multicenter Cohort Study. Infect Dis Ther 2023; 12:843-861. [PMID: 36520332 PMCID: PMC10017888 DOI: 10.1007/s40121-022-00734-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2022] [Accepted: 11/17/2022] [Indexed: 12/16/2022] Open
Abstract
INTRODUCTION International treatment guidelines recommend the rapid initiation of antiretroviral therapy (ART) with bictegravir (B)/emtricitabine (F)/tenofovir alafenamide (TAF) and dolutegravir (DTG)-based regimens for treatment-naïve persons living with HIV (PLWH) irrespective of their disease stage. However, we lack evidence of the virological efficacy, virological failure, and tolerability of coformulated B/F/TAF and DTG/ABC/3TC regimens in persons living with advanced HIV (PLWAH; defined as persons with a CD4+ count of < 200 cells/μL or an AIDS-related opportunistic illness [AOI] at or before ART initiation) in the era of rapid ART. METHODS This retrospective multicenter study enrolled treatment-naïve PLWAH initiating ART with coformulated DTG/ABC/3TC or B/F/TAF in 2019-2020. Viral suppression at week 48 was analyzed using FDA snapshot analysis. Between-regimen differences in time to viral suppression (< 50 copies/mL), virological failure, and regimen discontinuation were examined using a Cox proportional hazards model. Analysis was also performed using time to regimen discontinuation due to adverse reactions (ARs) as the outcome. RESULTS We enrolled 162 patients, including 61.1% on DTG/ABC/3TC and 38.9% on B/F/TAF. At week 48 after ART initiation, 73.47% on DTG/ABC/3TC and 85.71% on B/F/TAF achieved viral suppression (P = 0.178). We identified no between-regimen differences in time to viral suppression or virological failure, regardless of pre-ART viral load. Compared with the DTG/ABC/3TC group, regimen discontinuation was less prevalent in the B/F/TAF group (adjusted hazard ratio = 0.23, 95% CI 0.06-0.85, P = 0.027). The main reason for discontinuation in both groups was ARs (61.9% in the DTG/ABC/3TC and 50% in the B/F/TAF, P = 0.877), of which skin manifestations were the most common in both groups (61.5% in the DTG/ABC/3TC and 50% in the B/F/TAF, P = 0.756). DTG/ABC/3TC, same-day ART prescription, and AOI were risk factors for AR or virological failure-related regimen discontinuation. CONCLUSION In the real world, the risk of regimen discontinuation was higher in PLWAH on coformulated DTG/ABC/3TC than in those on B/F/TAF, with no difference in viral suppression or virological failure. Given the findings concerning the effect of same-day ART prescription and AOIs on AR or virological failure-related regimen discontinuation, individualized approaches to PLWAH are necessary.

Abstract
Overweight is increasingly prevalent in people living with HIV (PLWH), and is a high risk factor for metabolic disorders in this population. PLWH co-infected with hepatitis C virus (HCV) have a higher risk of metabolic disorders than their mono-infected counterparts. The putative relationship between cannabis use and body weight found in the general population has never been documented in HIV-HCV co-infected people. We tested whether cannabis use is associated with body mass index (BMI), overweight, and underweight in HCV co-infected PLWH (N = 992). Mixed-effects linear and logistic regression models were used to study the association between cannabis use and the three outcomes over time. After multivariable adjustment, cannabis use was inversely associated with BMI. Cannabis use was associated with a lower and higher risk of overweight and underweight, respectively. Cannabis use should be assessed and taken into account in the clinical management of the HIV-HCV co-infected population.

Mainoli B, Gonçalves N, Ferreira JJ, Mégarbane B. Potential drug-drug interactions in acute poisonings managed in the intensive care unit: Occurrence, risk factors and relationship to patient severity on admission. Basic Clin Pharmacol Toxicol 2021; 130:337-345. [PMID: 34873835 DOI: 10.1111/bcpt.13698] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Revised: 11/27/2021] [Accepted: 11/29/2021] [Indexed: 11/29/2022]
Abstract
Beyond the direct toxicity resulting from each drug in the poisoned patient, additional toxicities may result from drug-drug interactions (DDIs). We aimed to determine the frequency of potential DDIs in the poisoned patient and investigate whether DDIs are associated with severity. We conducted a 1-year cohort study in a toxicological ICU. DDIs were identified using an electronic interaction-checker tool. Among our 354 ICU poisoned patients, 134 (38%) presented at least one potential DDI between acute poisoning drugs and 180 (51%) at least one potential DDI between acute poisoning and long-term treatment drugs. Using multivariate analyses, previous suicide attempt was associated with the presence of potential DDIs between acute poisoning drugs in suicide attempt patients (P = 0.014). Chronic alcoholism (P = 0.005) and tobacco smoking (P = 0.022) were associated with the presence of potential DDIs between acute poisoning and long-term treatment drugs in recreational drug users. Presence of potential DDIs between acute poisoning and long-term treatment drugs was associated with catecholamine infusion (P = 0.022) in suicidal self-exposure patients. Presence of potential pharmacodynamic DDIs between acute poisoning and long-term treatment drugs was associated with aspiration pneumonia onset in recreational drug users (P = 0.03). ICU poisoned patients present a high rate of potential DDIs that may influence the outcome.
