RESUMEN
Antimicrobial stewardship programs (ASPs) can be expanded to the outpatient setting to serve as a first line of defense against coronavirus disease 19 (COVID-19) hospitalizations and to reduce the burden on emergency departments and acute-care hospitals. Given the numerous emergency use authorizations of monoclonal antibodies and oral antivirals, ASPs possess the expertise and leadership to direct ambulatory COVID-19 initiatives and transform it into a predominantly outpatient illness. In this review, we summarize the critical role and benefits of an ASP-championed ambulatory COVID-19 therapeutics program.
RESUMEN
BACKGROUND: Monoclonal antibodies (mAb) prevent COVID-19 progression when administered early. We compared mAb treatment outcomes among vaccinated and unvaccinated patients during Delta wave and assessed the feasibility of implementing stricter eligibility criteria in the event of mAb scarcity. METHODS: We conducted a retrospective observational study of casirivimab/imdevimab recipients with mild-to-moderate COVID-19 infection in an emergency department or outpatient infusion center (July 1-August 20, 2021). Primary outcome was all-cause hospital admission within 30 days post-treatment between vaccinated vs. unvaccinated patients during Delta surge in the Bronx, NY. RESULTS: A total of 250 patients received casirivimab/imdevimab (162 unvaccinated vs. 88 vaccinated). The median age was 39 years for unvaccinated patients, and 52 years for vaccinated patients (p < 0.0001). The median number of EUA criteria met was 1 for unvaccinated and 2 for vaccinated patients (p < 0.0001). Overall, 6% (15/250) of patients were admitted within 30 days post-treatment. Eleven unvaccinated patients (7%) were admitted within 30-days compared to 4 (5%) vaccinated patients (p = 0.48). CONCLUSIONS: All-cause 30-day admission was not statistically different between vaccinated and unvaccinated patients. When federal allocation of therapies is limited, programs must prioritize patients at highest risk of hospitalization and death regardless of vaccination status.

OBJECTIVE: To review the pharmacology, pharmacokinetics, pharmacodynamics, clinical efficacy, safety, administration, and role of amikacin liposome inhalation suspension (ALIS) in treatment of Mycobacterium avium complex (MAC) lung disease.
DATA SOURCES: A PubMed search using the terms "amikacin inhaled," "nebulized," and "liposome suspension" was performed. Selected infectious diseaseconference posters were also examined for relevant information. In addition, pertinent guidelines were reviewed.
STUDY SELECTION/DATA EXTRACTION: Guidelines for the management of nontuberculous mycobacterial infections from the American Thoracic Society/ Infectious Diseases Society of America and the British Thoracic Society were used to summarize guidelinebased therapy (GBT). A phase II and a phase III clinical trial were reviewed to evaluate the role of ALIS in the treatment of MAC lung disease.
DATA SYNTHESIS: ALIS is a new formulation of inhaled amikacin (AMK) indicated for the treatment of MAC lung disease refractory to GBT in adults who are not candidates for intravenous AMK. An ongoing clinical trial has demonstrated that once-daily ALIS plus GBT results in higher rates of culture conversion compared with GBT alone by month 6 among patients with a mean age of 65 years. The most common adverse reactions associated with ALIS were dysphonia, cough, bronchospasm, hemoptysis, and ototoxicity. Nephrotoxicity was uncommon.
CONCLUSION: ALIS has been shown to increase culture conversion rates when added to GBT in adults with difficult-to-treat MAC lung disease. ALIS is associated with high rates of pulmonary and auditory adverse reactions and a low risk of renal adverse reactions. ALIS may be an attractive treatment option for older adults who are at high risk for nephrotoxicity.
