Consensus recommendations for the use of novel antiretrovirals in persons with HIV who are heavily treatment-experienced and/or have multidrug-resistant HIV-1: Endorsed by the American Academy of HIV Medicine, American College of Clinical Pharmacy: An executive summary.

Treatment options are currently limited for persons with HIV-1 (PWH) who are heavily treatment-experienced and/or have multidrug-resistant HIV-1. Three agents have been approved by the U.S. Food and Drug Administration (FDA) since 2018, representing a significant advancement for this population: ibalizumab, fostemsavir, and lenacapavir. However, there is a paucity of recommendations endorsed by national and international guidelines describing the optimal use (e.g., selection and monitoring after initiation) of these novel antiretrovirals in this population. To address this gap, a modified Delphi technique was used to develop these consensus recommendations that establish a framework for initiating and managing ibalizumab, fostemsavir, or lenacapavir in PWH who are heavily treatment-experienced and/or have multidrug-resistant HIV-1. In addition, future areas of research are also identified and discussed in the main document.

Managing Modern Antiretroviral Therapy in the Intensive Care Unit: Overcoming Challenges for Critically Ill People With Human Immunodeficiency Virus.

People with human immunodeficiency virus (HIV) have a 50% excess risk for intensive care unit (ICU) admission, often for non-HIV-related conditions. Despite this, clear guidance for managing antiretroviral therapy (ART) in this setting is lacking. Selecting appropriate ART in the ICU is complex due to drug interactions, absorption issues, and dosing adjustments. Continuing ART in the ICU can be challenging due to organ dysfunction, drug interactions, and formulary limitations. However, with careful consideration, continuation is often feasible through dose adjustments or alternative administration methods. Temporary discontinuation of ART may be beneficial depending on the clinical scenario. Clinicians should actively seek resources and support to mitigate adverse events and drug interactions in critically ill people with HIV. Navigating challenges in the ICU can optimize ART and improve care and outcomes for critically ill people with HIV. This review aims to identify strategies for addressing the challenges associated with the use of modern ART in the ICU.

You'll have to call the attending: Impact of a longitudinal, "real-time" case-based infectious diseases elective on entrustable professional activities to enhance APPE readiness.

BACKGROUND AND PURPOSE: Transitioning from the didactic to experiential setting is challenging for student pharmacists, perhaps due to lack of experiences providing "real-time" clinician interaction. We describe findings from a semester-long infectious diseases (ID) didactic elective that utilized a national cohort of preceptors and faculty across the United States to mimic clinician interaction and "real-time" ID management of various disease states. The mechanics of this elective provide a framework for others to implement to enhance advanced pharmacy practice experience (APPE) readiness. EDUCATION ACTIVITY AND SETTING: Students enrolled in an ID elective course at a school of pharmacy participated in "real-time" acute care scenarios. They assisted in multidisciplinary management of a patient's infection, mimicking "rounds" on an APPE, via interaction with external pharmacist volunteers (playing the roles of other healthcare personnel). Additionally, students formally presented and discussed their cases within the class, further promoting learning while optimizing presentation skills. Pharmacist volunteers were surveyed to assess student performances as measured by four entrustable professional activities (EPAs). FINDINGS: A total of 48 volunteer opportunities occurred during two course offerings. Results from 43 surveys were analyzed (90% response rate). Of those responses, 22/24 (92%) played the role of attending physician, and 19/24 (79%) played the role of technician. Volunteers agreed that students met the four EPAs evaluated (agreement was 85-100%). SUMMARY: This semester-long elective provided "real-time" experience and feedback for pre-APPE students to enhance APPE readiness and reinforce EPAs. Students are likely to benefit from mimicked intra-professional interaction and augmented critical thinking skills that could be adapted to various disease states within pharmacy curricula.

A Baker's Dozen of Top Antimicrobial Stewardship Intervention Publications in 2022.

Keeping abreast of the antimicrobial stewardship-related articles published each year is challenging. The Southeastern Research Group Endeavor identified antimicrobial stewardship-related, peer-reviewed literature that detailed an actionable intervention during 2022. The top 13 publications were selected using a modified Delphi technique. These manuscripts were reviewed to highlight actionable interventions used by antimicrobial stewardship programs to capture potentially effective strategies for local implementation.

Candidemia in Adult Patients in the ICU: A Reappraisal of Susceptibility Testing and Antifungal Therapy.

OBJECTIVE: To provide updates on the epidemiology and recommendations for management of candidemia in patients with critical illness. DATA SOURCES: A literature search using the PubMed database (inception to March 2023) was conducted using the search terms "invasive candidiasis," "candidemia," "critically ill," "azoles," "echinocandin," "antifungal agents," "rapid diagnostics," "antifungal susceptibility testing," "therapeutic drug monitoring," "antifungal dosing," "persistent candidemia," and "Candida biofilm." STUDY SELECTION/DATA EXTRACTION: Clinical data were limited to those published in the English language. Ongoing trials were identified through ClinicalTrials.gov. DATA SYNTHESIS: A total of 109 articles were reviewed including 25 pharmacokinetic/pharmacodynamic studies and 30 studies including patient data, 13 of which were randomized controlled clinical trials. The remaining 54 articles included fungal surveillance data, in vitro studies, review articles, and survey data. The current 2016 Infectious Diseases Society of America (IDSA) Clinical Practice Guideline for the Management of Candidiasis provides recommendations for selecting empiric and definitive antifungal therapies for candidemia, but data are limited regarding optimized dosing strategies in critically ill patients with dynamic pharmacokinetic changes or persistent candidemia complicated. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: Outcomes due to candidemia remain poor despite improved diagnostic platforms, antifungal susceptibility testing, and antifungal therapy selection for candidemia in critically ill patients. Earlier detection and identification of the species causing candidemia combined with recognition of patient-specific factors leading to dosing discrepancies are crucial to improving outcomes in critically ill patients with candidemia. CONCLUSIONS: Treatment of candidemia in critically ill patients must account for the incidence of non-albicans Candida species and trends in antifungal resistance as well as overcome the complex pathophysiologic changes to avoid suboptimal antifungal exposure.

Therapeutic Options for Adult Patients With Persistent Methicillin-Susceptible Staphylococcus aureus Bacteremia: A Narrative Review.

OBJECTIVE: To compare the efficacy of antimicrobial therapies used in the management of persistent methicillin-susceptible Staphylococcus aureus (MSSA) bacteremia. DATA SOURCES: A literature search using the PubMed database (inception to December 2022) was conducted using the search terms "Staphylococcus aureus bacteremia," "methicillin-susceptible Staphylococcus aureus bacteremia," "persistent methicillin-susceptible Staphylococcus aureus bacteremia," and "refractory methicillin-susceptible Staphylococcus aureus bacteremia ." In addition, therapeutic agents which could be used as treatment for MSSA including "nafcillin," "oxacillin," "cefazolin," "ceftaroline," "gentamicin," "rifampin," and "daptomycin" were also combined with the aforementioned search terms to capture data using these agents. STUDY SELECTION/DATA EXTRACTION: Clinical data were limited to those published in the English language. Articles and abstracts were considered for inclusion in addition to ongoing trials identified through ClinicalTrials.gov. DATA SYNTHESIS: A total of 78 articles were reviewed including 17 in vitro or animal model studies and 39 studies including patient data. The remaining 22 articles included guidelines, review articles, and editorials. Recent data evaluating use of dual ß-lactam regimens for persistent MSSA bacteremia were limited to 8 case reports or case series. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: At present, there is little guidance on how to best manage patients with persistent MSSA bacteremia. This narrative review collates the available data to assist clinicians in selecting the best possible antimicrobial regimen when facing this clinical conundrum. CONCLUSIONS: Modification of antimicrobial therapy, in conjunction with source control and infectious diseases consultation, may all be necessary to sterilize blood cultures in patients with persistent MSSA bacteremia.

Personalizing prevention: Advances in pharmacotherapy for HIV prevention.

The HIV epidemic continues to pose a significant burden on the healthcare system. Although the incidence of annual new infections is decreasing, health disparities persist and most new infections remain concentrated into different racial, ethnic, and minority groups. Pre-exposure prophylaxis (PrEP), which involves those at high risk of acquiring HIV to take chronic medications to prevent acquisition of the virus, is key to preventing new HIV infections. The purpose of this article is to review medication therapies for PrEP and examine their role in personalizing PrEP in different patient populations. Additionally, new medications currently under development for PrEP are reviewed, as well as treatment as prevention (TasP) and post-exposure prophylaxis (PEP). There are currently four medications available for PrEP: the oral options of co-formulated emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) or emtricitabine/tenofovir alafenamide (FTC/TAF); injectable long-acting cabotegravir (CAB-LA); and the vaginal ring dapivirine (DPV-VR). FTC/TAF is not currently indicated for persons at risk for HIV through vaginal sex due to lack of studies, but trials are currently ongoing. DPV-VR is available in Zimbabwe and South Africa and has been endorsed by the World Health Organization but is not currently available in the United States. Several agents are also in development for use in PrEP: the novel long-acting injectable lenacapavir, a first-in-class capsid inhibitor, which has no cross-resistance to any existing HIV drug class; the subdermal implant islatravir, a first-in-class translocation inhibitor; and VRC01, a broadly neutralizing antibody (bnAb) which has been evaluated in proof-of-concept studies that may lead to the development of more potent bnAbs. Overall, PrEP is highly effective at preventing HIV infection in high-risk populations. Identifying optimal PrEP regimens in different patient populations is complex and must consider patient-specific factors and medication cost and access considerations. Lastly, providers should consider individual patient preferences with regard to prevention to improve access, retention in care, and adherence.

Kimyrsa and Orbactiv - A Tale of Two Formulations.

Kimyrsa is a new formulation (NF) of the original formulation of oritavancin ([OF] Orbactiv). Comparatively, the obvious benefit with this product is the shortened infusion time and flexibility with solution compatibility, but otherwise maintains a similar pharmacokinetic and microbiologic profile. At present, the NF lacks significant real-world experience relative to other available lipoglycopeptides and thus its place in therapy remains difficult to predict but would not be expected to be significantly different than its OF.

A Baker's Dozen of Top Antimicrobial Stewardship Intervention Publications for Hospitalized Patients in 2021.

The Southeastern Research Group Endeavor (SERGE-45) identified antimicrobial stewardship-related, peer-reviewed literature that detailed an "actionable" intervention among hospitalized populations during 2021. The top 13 publications were selected using a modified Delphi technique. These manuscripts were reviewed to highlight "actionable" interventions used by antimicrobial stewardship programs in hospitalized populations to capture potentially effective strategies for local implementation.

The association between empiric antimicrobial therapy and the risk of clinical failure in critically ill patients with aspiration pneumonia.

WHAT IS KNOWN AND OBJECT: Aspiration pneumonia is a clinically important infectious process that can result in increased morbidity and mortality. Empiric antimicrobial therapy with activity against anaerobes has been a standard practice based on previous studies, which isolated anaerobes from respiratory cultures. Recent studies have failed to identify anaerobes as causative pathogens, however, these studies did not assess patient outcomes based on the presence or absence of anaerobic coverage. METHODS: This retrospective cohort study evaluated patients at least 18 years of age requiring mechanical ventilation diagnosed with aspiration pneumonia between 1 October 2020 and 31 July 2021. The primary outcome was the incidence of clinical failure. Secondary outcomes included the time to clinical failure, the incidence of Clostridioides difficile infections and development of multidrug-resistant infections, as well as time on mechanical ventilation and intensive care unit length of stay. RESULTS: A total of 141 patients were included with 83 patients initially receiving anaerobic coverage and 58 patients treated without anaerobic coverage. There was no difference in the incidence of clinical failure between cohorts (18.1% vs. 22.4%; p = 0.41). There was a statistically significant difference in anaerobic escalations with more escalations in the cohort without anaerobic coverage (0% vs. 20.7%; p < 0.0001). Patients initially treated with drugs with anaerobic activity had a higher incidence of multidrug resistant infections on current admission (7.2% vs. 0%; p = 0.04) and a longer length of intensive care unit stay. WHAT IS NEW AND CONCLUSION: In critically ill adults with aspiration pneumonia, our study found no difference in clinical failure based on the presence or absence of empiric anaerobic coverage adding to evolving literature suggesting that anaerobic coverage is not routinely warranted in this patient population. Interpretation of the results needs to consider, however, that the retrospective design led to the inclusion of sicker patients in the anaerobic cohort. The frequency of empiric anaerobic coverage demonstrates the need for a prospective randomized control trial to confirm these findings.

A primer on Post-COVID-19 conditions and implications for clinical pharmacists.

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and is largely viewed as an acute illness involving multiple organ systems. In the wake of the acute illness, many survivors fully recover and return to baseline, while others suffer from a wide range of lingering symptoms collectively known as "post-COVID conditions". The recognition of these conditions as a clinical entity represents the first step in developing a targeted plan for recovery and symptom mitigation. While interventions to directly minimize or reduce new, recurrent, or persistent symptoms are currently unknown, pharmacists can play a key role in optimizing management of these patients.

These manuscripts were reviewed to highlight the actionable intervention used by antimicrobial stewardship programs to provide key stewardship literature for teaching and training and to identify potential intervention opportunities within one's institution.

Multicenter, Observational Cohort Study Evaluating Third-Generation Cephalosporin Therapy for Bloodstream Infections Secondary to Enterobacter, Serratia, and Citrobacter Species.

OBJECTIVES: There is debate on whether the use of third-generation cephalosporins (3GC) increases the risk of clinical failure in bloodstream infections (BSIs) caused by chromosomally-mediated AmpC-producing Enterobacterales (CAE). This study evaluates the impact of definitive 3GC therapy versus other antibiotics on clinical outcomes in BSIs due to Enterobacter, Serratia, or Citrobacter species. METHODS: This multicenter, retrospective cohort study evaluated adult hospitalized patients with BSIs secondary to Enterobacter, Serratia, or Citrobacter species from 1 January 2006 to 1 September 2014. Definitive 3GC therapy was compared to definitive therapy with other non-3GC antibiotics. Multivariable Cox proportional hazards regression evaluated the impact of definitive 3GC on overall treatment failure (OTF) as a composite of in-hospital mortality, 30-day hospital readmission, or 90-day reinfection. RESULTS: A total of 381 patients from 18 institutions in the southeastern United States were enrolled. Common sources of BSIs were the urinary tract and central venous catheters (78 (20.5%) patients each). Definitive 3GC therapy was utilized in 65 (17.1%) patients. OTF occurred in 22/65 patients (33.9%) in the definitive 3GC group vs. 94/316 (29.8%) in the non-3GC group (p = 0.51). Individual components of OTF were comparable between groups. Risk of OTF was comparable with definitive 3GC therapy vs. definitive non-3GC therapy (aHR 0.93, 95% CI 0.51-1.72) in multivariable Cox proportional hazards regression analysis. CONCLUSIONS: These outcomes suggest definitive 3GC therapy does not significantly alter the risk of poor clinical outcomes in the treatment of BSIs secondary to Enterobacter, Serratia, or Citrobacter species compared to other antimicrobial agents.

Doravirine: A Return of the NNRTI Class?

Objective: To compare and contrast doravirine (DOR) with other agents in the nonnucleoside reverse transcriptase inhibitor (NNRTI) class, review safety and efficacy data from both completed and ongoing clinical trials, and outline the potential place in therapy of DOR. Data Sources: A literature search using the PubMed database (inception to June 2019) was conducted using the search terms HIV, doravirine, non-nucleoside reverse transcriptase inhibitor, NNRTI, and MK-1439. Study Selection and Data Extraction: Clinical data were limited to those published in the English language from phase 2 or 3 clinical trials. Ongoing trials were identified through ClinicalTrials.gov. Data Synthesis: DOR was approved by the US Food and Drug Administration on the strength of 2 phase 3 randomized, double-blind, noninferiority clinical trials with additional studies currently underway examining its utility in other clinical scenarios. Relevance to Patient Care and Clinical Practice: The role of NNRTIs as part of antiretroviral (ARV) therapy has diminished in recent years given the introduction of more tolerable individual ARV agents and regimens. Despite this, new agents are still needed in the therapeutic arena because treatment failure as well as intolerance can still occur with many first-line therapies. The optimal place in therapy of DOR remains to be defined. Conclusions: DOR is a new NNRTI that represents a potential treatment option for treatment-naïve patients, without many of the previously described untoward effects of the NNRTI class.

A Baker's Dozen of Top Antimicrobial Stewardship Intervention Publications in 2017.

These manuscripts were reviewed to highlight the "actionable" intervention used by antimicrobial stewardship programs to provide key stewardship literature for training and teaching and identify potential intervention opportunities within their institutions.

Integrase Inhibitors: After 10 Years of Experience, Is the Best Yet to Come?

The era of the integrase strand transfer inhibitors (INSTIs) for the treatment of human immunodeficiency virus (HIV) infection began with raltegravir in 2007. Since that time, several other INSTIs have been introduced including elvitegravir, dolutegravir, and, most recently, bictegravir, that have shown great utility as part of antiretroviral regimens in both treatment-naive and treatment-experienced patients. At present, antiretroviral guidelines fully endorse the INSTI class as part of all first-line treatment regimens. After 10 years of experience with INSTIs, newer agents are on the horizon such as cabotegravir and MK-2048 for potential use as either HIV pre-exposure prophylaxis or maintenance therapy. This review provides a brief overview of the INSTI class including agents currently available and those still in development, reviews available data from both completed and ongoing clinical trials, and outlines simplification strategies using INSTIs.

Vancomycin plus nafcillin salvage for the treatment of persistent methicillin-resistant Staphylococcus aureus bacteremia following daptomycin failure: a case report and literature review.

BACKGROUND: Evidence supporting beta-lactam plus vancomycin synergy for methicillin-resistant Staphylococcus aureus (MRSA) continues to grow. Current in vivo evidence demonstrates that combination therapy is associated with shorter time to blood sterilization than vancomycin monotherapy. However, this combination has not been reported as salvage therapy for persistent MRSA bacteremia. CASE REPORT: We report a case of an 81-year-old male who was successfully treated with vancomycin plus nafcillin after failing vancomycin monotherapy, daptomycin monotherapy, and daptomycin plus gentamicin combination therapy. The patient originally presented with sepsis from a suspected urinary tract infection. Blood cultures drawn on days 1, 3, 5, 15, 19, 23, and 28 remained positive for MRSA despite multiple antimicrobial therapy changes. On day 29, therapy was changed to vancomycin plus nafcillin. Blood cultures drawn on day 32 remained negative. After 11 days, nafcillin was changed to piperacillin-tazobactam due to an infected decubitus ulcer. The combination was continued for 42 days after achieving blood sterility, 71 days after the patient originally presented. Evidence regarding salvage therapy for persistent bacteremia is sparse and is limited to case reports and case series. CONCLUSION: This case report supports that vancomycin plus an anti-staphylococcal beta-lactam combination should be further studied as salvage therapy for persistent MRSA bacteremia.

HIV Integrase Inhibitor Pharmacogenetics: An Exploratory Study.

BACKGROUND AND OBJECTIVES: Integrase strand transfer inhibitors (INSTIs), dolutegravir, elvitegravir, and raltegravir, have become integral in the treatment of HIV, with close monitoring of continued efficacy and tolerability. As side effect occurrence varies among subjects receiving these drugs, we sought to perform an exploratory analysis examining the role of several single-nucleotide polymorphisms (SNPs) on drug concentration changes, selected clinical outcomes, and the occurrence of subject-reported adverse events. METHODS: Adults (aged ≥ 18 years) receiving INSTI-based regimens for treatment of HIV were recruited and genotyped with an iPLEX ADME PGx Pro v1.0 Panel. Multiple linear or logistic regression with covariates [age, sex, BMI, regimen (in the across-regimen group), regimen duration, and baseline variables (for continuous parameters)] was used to detect significant (p < 0.05) association of selected clinical data with genetic variants within the study population. RESULTS: In a sample (n = 88) with a median age of 52.5 years (IQR 45.7-57.2) being predominately Caucasian (88.6%) and male (86.4%), this exploratory study discovered several associations between variables and SNPs, when using INSTIs. Abnormal dream occurrence was statistically different (p = 0.028) between regimens. Additionally, several SNPs were found to be associated with adverse event profiles primarily when all regimens were grouped together. CONCLUSION: The associations found in this study point to a need for further assessment, within the population living with HIV, of factors contributing to unfavorable subject outcomes. These exploratory findings require confirmation in larger studies, which then may investigate pharmacogenetic mechanisms.

Comparison of perceived personality traits between the pharmacy residents admitted through the match or scramble process.

INTRODUCTION: The purpose of this study is to determine whether certain personality traits are as prominent in pharmacy practice residents who obtain positions through the post-Match process, previously referred to as the Scramble, as compared to residents who match directly with programs. METHODS: Pharmacy residency program directors (RPDs) across the United States were asked to complete an electronic survey that gauged RPD perceptions of 13 personality traits commonly seen in pharmacy residents. RPDs were requested to separately evaluate residents who Scrambled and Matched to their respective programs. Exploratory factor analysis (EFA) was used to determine factor structure for the personality traits and to assess whether factors associate differentially between Matched and Scrambled residents. RESULTS: A total of 1876 RPDs of post-graduate year one (PGY1), post-graduate year two (PGY2), and combined PGY1 and PGY2 pharmacy residency programs were contacted for study participation with a response rate of 21 percent. Demographic variables related to program type and number of residents per class were similar between Scrambled and Matched groups. The EFA identified two factors across 13 traits: we termed them as traditional traits and grit-like traits, and they significantly differed between the Scramble and Match groups. RPD perception of traditional traits (nine traits) were significantly higher in the Match group (p < 0.05), whereas perceived grit-like traits (four traits) were significantly higher in the Scramble group (p < 0.0001). CONCLUSION: Residency candidates who Match versus candidates who Scramble are perceived to have unique and significantly different personality traits.
