Characteristics, Comorbidities, and Outcomes in a Multicenter Registry of Patients With Human Immunodeficiency Virus and Coronavirus Disease 2019.

BACKGROUND: People living with human immunodeficiency virus (HIV) may have numerous risk factors for acquiring coronavirus disease 2019 (COVID-19) and developing severe outcomes, but current data are conflicting. METHODS: Health-care providers enrolled consecutively, by nonrandom sampling, people living with HIV (PWH) with lab-confirmed COVID-19, diagnosed at their facilities between 1 April and 1 July 2020. Deidentified data were entered into an electronic Research Electronic Data Capture (REDCap) system. The primary endpoint was a severe outcome, defined as a composite endpoint of intensive care unit (ICU) admission, mechanical ventilation, or death. The secondary outcome was the need for hospitalization. RESULTS: There were 286 patients included; the mean age was 51.4 years (standard deviation, 14.4), 25.9% were female, and 75.4% were African American or Hispanic. Most patients (94.3%) were on antiretroviral therapy, 88.7% had HIV virologic suppression, and 80.8% had comorbidities. Within 30 days of testing positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), 164 (57.3%) patients were hospitalized, and 47 (16.5%) required ICU admission. Mortality rates were 9.4% (27/286) overall, 16.5% (27/164) among those hospitalized, and 51.5% (24/47) among those admitted to an ICU. The primary composite endpoint occurred in 17.5% (50/286) of all patients and 30.5% (50/164) of hospitalized patients. Older age, chronic lung disease, and hypertension were associated with severe outcomes. A lower CD4 count (<200 cells/mm3) was associated with the primary and secondary endpoints. There were no associations between the ART regimen or lack of viral suppression and the predefined outcomes. CONCLUSIONS: Severe clinical outcomes occurred commonly in PWH with COVID-19. The risks for poor outcomes were higher in those with comorbidities and lower CD4 cell counts, despite HIV viral suppression. CLINICAL TRIALS REGISTRATION: NCT04333953.

Fostemsavir: A Novel Attachment Inhibitor for Patients With Multidrug-Resistant HIV-1 Infection.

OBJECTIVE: To review the efficacy and safety of fostemsavir (FTR) for the treatment of multidrug-resistant HIV-1 infection in heavily treatment-experienced adults who are failing their current antiretroviral regimen. DATA SOURCES: Clinical trials and review articles were obtained through PubMed (2015 to July 2020) using the search terms fostemsavir, BMS-663068, and GSK3684934. STUDY SELECTION AND DATA EXTRACTION: All relevant articles, trials, and abstracts in the English language were included. DATA SYNTHESIS: FTR demonstrates a novel mechanism of action, preventing virus attachment to the host CD4 receptor. FTR extended-release 600-mg tablets every 12 hours orally has proven beneficial in obtaining viral suppression for heavily treatment-experienced patients with multidrug-resistant infection refractory to other agents, as indicated in phase 3 trials. Treatment courses were evaluated to 96 weeks with significant viral load reductions noted within the first 24 weeks. Adverse events commonly reported include nausea, vomiting, diarrhea, fatigue, and headache. Serious events and fatality were not attributed to FTR and occurred because of advancement of HIV or other acute infection. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: FTR presents a new treatment option for patients with multidrug resistance and intolerability to other medications. The favorable adverse effect profile of FTR alongside the limited drug interaction profile makes it a viable option in a salvage regimen. CONCLUSIONS: FTR provides an alternative agent when composing a regimen for patients with multidrug-resistant HIV-1 infection. It is generally well tolerated, with few significant interactions, and neither renal nor hepatic dose adjustments are required.

A Call to Action: The Role of Antiretroviral Stewardship in Inpatient Practice, a Joint Policy Paper of the Infectious Diseases Society of America, HIV Medicine Association, and American Academy of HIV Medicine.

Persons living with human immunodeficiency virus (HIV) and others receiving antiretrovirals are at risk for medication errors during hospitalization and at transitions of care. These errors may result in adverse effects or viral resistance, limiting future treatment options. A range of interventions is described in the literature to decrease the occurrence or duration of medication errors, including review of electronic health records, clinical checklists at care transitions, and daily review of medication lists. To reduce the risk of medication-related errors, antiretroviral stewardship programs (ARVSPs) are needed to enhance patient safety. This call to action, endorsed by the Infectious Diseases Society of America, the HIV Medicine Association, and the American Academy of HIV Medicine, is modeled upon the success of antimicrobial stewardship programs now mandated by the Joint Commission. Herein, we propose definitions of ARVSPs, suggest resources for ARVSP leadership, and provide a summary of published, successful strategies for ARVSP that healthcare facilities may use to develop locally appropriate programs.

Consensus recommendations for use of long-acting antiretroviral medications in the treatment and prevention of HIV-1: Endorsed by the American Academy of HIV Medicine, American College of Clinical Pharmacy, Canadian HIV and Viral Hepatitis Pharmacists Network, European AIDS Clinical Society, and Society of Infectious Diseases Pharmacists: An executive summary.

Five long-acting (LA) antiretrovirals (ARVs) are currently available in a limited number of countries worldwide for HIV-1 prevention or treatment - cabotegravir, rilpivirine, lenacapavir, ibalizumab, and dapivirine. Implementing use of LA ARVs in routine clinical practice requires significant changes to the current framework of HIV-1 prevention, treatment, and service provision. Given the novelty, complexity, and interdisciplinary requirements of safe and optimal use of LA ARVs, consensus recommendations on the use of LA ARVs will assist clinicians in optimizing use of these agents. The purpose of these recommendations is to provide guidance for the clinical use of LA ARVs for HIV-1 treatment and prevention. In addition, future areas of research are identified and discussed.

HIV: how to manage heavily treatment-experienced patients.

Although decreasing in prevalence, heavily treatment-experienced (HTE) persons with limited options for HIV treatment present unique complexities, even amongst experienced providers, as there is no single approach to successful management. HTE patients are described as those having two or less antiretroviral (ARV) classes available for use with limited fully active ARV agents within each class. A detailed understanding of the underlying processes that caused previous treatment failures, diagnostics to define resistance, resistance mechanisms and ARV pharmacology should all function in tandem to determine the next steps of clinical care. This narrative review provides an overview of the clinician approach to care, including diagnostics, approaches to regimen creation, relevant resources, and a broad array of both currently available and upcoming ARVs that may be used in regimens for HTE patients.

Crushing and Splitting Direct-Acting Antivirals for Hepatitis C Virus Treatment: A Case Series and Literature Review.

Limited data exist regarding the use of direct-acting antivirals (DAAs) for hepatitis C virus (HCV) in patients who are unable to swallow tablets. This case series describes HCV treatment in patients requiring tablet manipulation, providing evidence for safety and effectiveness of HCV DAA tablet manipulation.

Predicting Treatment Failure for Initiators of Hepatitis C Virus Treatment in the era of Direct-Acting Antiviral Therapy.

Introduction: Hepatitis C virus (HCV), the leading cause of advanced liver disease, has enormous economic burden. Identification of patients at risk of treatment failure could lead to interventions that improve cure rates. Objectives: Our goal was to develop and evaluate a prediction model for HCV treatment failure. Methods: We analyzed HCV patients initiating direct-acting antiviral therapy at four United States institutions. Treatment failure was determined by lack of sustained virologic response (SVR) 12 weeks after treatment completion. From 20 patient-level variables collected before treatment initiation, we identified a subset associated with treatment failure in bivariate analyses. In a derivation set, separate predictive models were developed from 100 bootstrap samples using logistic regression. From the 100 models, variables were ranked by frequency of selection as predictors to create four final candidate models, using cutoffs of ≥80%, ≥50%, ≥40%, and all variables. In a validation set, predictive performance was compared across models using area under the receiver operating characteristic curve. Results: In 1,253 HCV patients, overall SVR rate was 86.1% (95% CI = 84.1%, 88.0%). The AUCs of the four final candidate models were: ≥80% = 0.576; ≥50% = 0.605; ≥40% = 0.684; all = 0.681. The best performing model (≥40%) had significantly better predictive ability than the ≥50% (p = 0.03) and ≥80% models (p = 0.02). Strongest predictors of treatment failure were older age, history of hepatocellular carcinoma, and private (vs. government) insurance. Conclusion: This study highlighted baseline factors associated with HCV treatment failure. Treatment failure prediction may facilitate development of data-driven clinical tools to identify patients who would benefit from interventions to improve SVR rates.

Perceptions of Long-Acting Injectable Antiretroviral Treatment Regimens in a United States Urban Academic Medical Center.

Patient acceptance of long-acting injectable antiretroviral (LAI-ARV) HIV-1 regimens will determine uptake. Although previous literature reports high satisfaction, these data stem from clinical trials subject to selection bias. This cross-sectional survey from the HIV practices of an urban academic medical center assessed perceptions and preferences using Likert scales toward overall acceptability, proposed frequencies, injection-site reaction durations, and distribution venue. 59% of surveys were completed resulting 202 respondents. 60% were male, 72% black, and the median age was 49 (IQR 36-58). 93% reported a once daily tablet frequency, 69% reported single tablet regimens, and 59% reported missing zero doses in the prior 30 days. Patients self-categorized as likely (57%) or unlikely (43%) to accept LAI-ARV. Both decreasing frequencies between injections and durations of injection-site reactions resulted higher acceptability scores. 57% of respondents preferred receiving an injectable from their clinician's office over other potential options. These data demonstrate positive LAI-ARV acceptance potential.

Hepatitis C Update and Expanding the Role of Primary Care.

Primary care physicians (PCPs) are increasing their role in the fight against the Hepatitis C Virus (HCV). Approximately 3.5 million Americans currently live with chronic HCV with rising incidence among young persons, especially those affected by the opioid epidemic. Online guidelines and drug interaction checkers streamline treatment and increase accessibility for both patients and providers. Although treatment with new Direct Acting Antiviral agents ensure cure rates that routinely exceed 95%, as well as cause fewer adverse effects than previously available interferon-based regimens, some states still restrict access to HCV treatment, including by mandating which providers can prescribe and treat HCV. This special communication reviews HCV treatment resources, discusses data demonstrating similar cure rates between PCPs and specialists, and argues that capacity-building among PCPs will be necessary to control the HCV epidemic.

The Pharmacist's Expanding Role in HIV Pre-Exposure Prophylaxis.

The efficacy of pre-exposure prophylaxis (PrEP) to prevent HIV has been firmly established; however, the success of PrEP largely depends on access to care as well as high levels of medication adherence. One of the key areas of focus for the National HIV/AIDS Strategy for 2020 in the United States calls for full access to comprehensive PrEP services where appropriate and desired, with support for medication adherence. Despite advances and advocacy for PrEP since approval for adults in 2012, large rates of prescribing disparity exist among gender and race/ethnicity. In 2016, only 3.7% of all PrEP users were women and only 11.2% were black. As one of the most widely accessible health care resources, pharmacists are well positioned to improve patient understanding, promote medication adherence, provide key risk reduction counseling, and enhance PrEP efficacy. Pharmacists' knowledge and accessibility in nearly every urban and rural community can be leveraged as part of a comprehensive HIV prevention strategy to expand access to care and improve population health. As trusted health care professionals, pharmacists develop a strong rapport with patients and may be the key to address current disparities in PrEP prescribing patterns as well as serve as an essential liaison between patients and other members of the multi-disciplinary care team. The purpose of this review is to summarize available data on pharmacist involvement in various models of care providing PrEP services and to identify opportunities to maximize and expand the role of the pharmacist to improve access to PrEP.

Impact of an Antiretroviral Stewardship Team on the Care of Patients With Human Immunodeficiency Virus Infection Admitted to an Academic Medical Center.

BACKGROUND: Interdisciplinary antiretroviral stewardship teams, comprising a human immunodeficiency virus pharmacist specialist, an infectious diseases physician, and associated learners, have the ability to assist in identification and correction of inpatient antiretroviral-related errors. METHODS: Electronic medical records of patients with antiretroviral orders admitted to our hospital were evaluated for the number of interventions made by the stewardship team, number of admissions with errors identified, risk factors for occurrence of errors, and cost savings. Risk factors were analyzed by means of multivariable logistic regression. Cost savings were estimated by the documentation system Clinical Measures. RESULTS: A total of 567 admissions were included for analysis in a 1-year study period. Forty-three percent of admissions (245 of 567) had ≥1 intervention, with 336 interventions in total. The following were identified as risk factors for error: multitablet inpatient regimen (odds ratio, 1.834; 95% confidence interval, 1.160-2.899; P = .009), admission to the intensive care unit (2.803; 1.280-6.136; P = .01), care provided by a surgery service (1.762; 1.082-2.868; P = .02), increased number of days reviewed (1.061; 1.008-1.117; P = .02), and noninstitutional outpatient provider (1.375; .972-1.946; P = .07). The 1-year cost savings were estimated to be $263 428. CONCLUSIONS: Antiretroviral stewardship teams optimize patient care through identification and correction of antiretroviral-related errors. Errors may be more common in patients with multitablet inpatient regimens, admission to the intensive care unit, care provided by a surgery service, and increased number of hospital days reviewed. Once antiretroviral-related errors are identified, the ability to correct them provides cost savings.

Expanding Hepatitis C Virus Care and Cure: National Experience Using a Clinical Pharmacist-Driven Model.

BACKGROUND: The US National Viral Hepatitis Action Plan depends on additional providers to expand hepatitis C virus (HCV) treatment capacity in order to achieve elimination goals. Clinical pharmacists manage treatment and medication within interdisciplinary teams. The study's objective was to determine sustained virologic response (SVR) rates for clinical pharmacist-delivered HCV therapy in an open medical system. METHODS: Investigators conducted a multicenter retrospective cohort study of patients initiating direct-acting antivirals from January 1, 2014, through March 12, 2018. Data included demographics, comorbidities, treatment, and clinical outcomes. The primary outcome of SVR was determined for patients initiating (intent-to-treat) and those who completed (per-protocol) treatment. Chi-square tests were conducted to identify associations between SVR and adverse reactions, drug-drug interactions, and adherence. RESULTS: A total of 1253 patients initiated treatment; 95 were lost to follow-up, and 24 discontinued therapy. SVR rates were 95.1% (1079/1134) per protocol and 86.1% (1079/1253) intent to treat. The mean age (SD) was 57.4 (10.1) years, the mean body mass index (SD) was 28.7 (6.2) kg/m2, 63.9% were male, 53.7% were black, 40.3% were cirrhotic, 88.4% were genotype 1, and 81.6% were treatment-naïve. Patients missing ≥1 dose had an SVR of 74.9%; full adherence yielded 90% (P < .0001). CONCLUSIONS: HCV treatment by clinical pharmacists in an open medical system resulted in high SVR rates comparable to real-world studies with specialists and nonspecialists. These findings demonstrate the success of a clinical pharmacist-delivered method for HCV treatment expansion and elimination.

HIV Pre-Exposure Prophylaxis and Women: Survey of the Knowledge, Attitudes, and Beliefs in an Urban Obstetrics/Gynecology Clinic.

Uptake of HIV pre-exposure prophylaxis (PrEP) is low among women at risk for HIV acquisition. Of 468,000 women, whom the United States Centers for Disease Control and Prevention estimates to be eligible for PrEP, only 10,000 unique women have begun therapy through the third quarter of 2015. These data suggest insufficient HIV prevention efforts. This study, conducted at the site of an urban academic medical center with an emergency department HIV prevalence rate of 4%, assesses the knowledge, attitudes, and beliefs of women toward PrEP. A self-administered survey was conducted among women at a family planning obstetrics/gynecology clinic at Temple University Hospital (Philadelphia, PA). Participants assessed their HIV acquisition risk and answered eight questions regarding knowledge, attitudes, and beliefs toward PrEP. Three hundred eighty-nine surveys met inclusion criteria. Sixty-five percent of women were black, and 73% were between 18 and 33 years of age. The median self-perceived risk score was 0 (interquartile range = 2) using a Likert scale. Thirty-three percent of women believed that PrEP could work, and 27% knew that such a regimen existed. Concerns existed toward cost (44%) and side effects (39%). Fifty-seven percent of women surveyed stated that they would take a medication to prevent HIV, and 64% felt comfortable discussing the subject with her doctor. Our data demonstrate a lack of PrEP knowledge, although willingness for uptake among women at risk for HIV acquisition, and a need for directed education and outreach.

Ibalizumab.

PURPOSE OF REVIEW: Antiretroviral options for patients infected with multiclass resistant HIV-1 warrant the development of new agents with unique mechanisms of action and modes of delivery. Here we review one such agent, ibalizumab, a parenteral CD4 postattachment inhibitor that has demonstrated efficacy as part of combination antiretroviral therapy in the treatment of HIV-1. RECENT FINDINGS: In a phase III clinical trial in HIV-infected participants with multiclass antiretroviral drug resistance, the intravenous administration of ibalizumab led to declines in plasma HIV-1 RNA more than 0.5 log in 83% of participants at 1 week. An optimized background antiretroviral regimen was then added, and plasma HIV-1 RNA became less than 50 copies/ml in 43% of participants at 24 weeks. Adverse effects of ibalizumab were uncommon and generally low grade. Ibalizumab was approved by the US Food and Drug Administration on March 16, 2018, under the trade name Trogarzo. SUMMARY: Ibalizumab has demonstrated both safety and efficacy in the treatment of HIV-1 infection. Its primary use will be in the setting of multidrug resistant virus as part of combination antiretroviral therapy. Further enhancements of ibalizumab to prolong its clearance and broaden its activity are in development.
