Background: Combination therapy for Enterococcus faecalis was established in the 1940s due to high rates of treatment failure, especially for infective endocarditis (IE). However, during this period antimicrobials were limited, optimal dosing was unknown, and development of resistance was rapid. Today, nearly 80 years later, combination therapy is still the standard practice for IE caused by E. faecalis despite improvements in antimicrobial availability, activity, and evidence-based, optimized antimicrobial dosing. These treatment decisions are guided by in vitro synergy principles and are frequently extrapolated to E. faecalis bloodstream infections (BSI) without IE. The paucity of clinical data to support this practice, paired with the known risks from unnecessary antibiotic exposure, makes further research and clinical guidance necessary. Methods: This single-center retrospective observational study of hospitalized adult patients with E. faecalis BSI treated with combination therapy aimed to describe treatment approaches and outcome data. Results: Between 1 January 2017, and 30 September 2024, 358 patients were screened, and 54 met study inclusion criteria. IE was present in 53.7% of patients, and 25.9% met the composite outcome (30-day mortality, 60-day hospital readmission, and/or 60-day recurrence). Adverse events were noted in 5.6% of patients. Conclusions: Observational data from this review supports the hypothesis that guideline recommendations for the use of combination therapy in E. faecalis IE are occasionally extrapolated to patients without IE. Given the in vitro and dated observational data used as the basis for these recommendations and the risks associated with unnecessary antibiotic exposure, more extensive, prospective, interventional studies are needed to address this dogmatic practice surrounding a high-morbidity, high-mortality disease state.

Background/Objectives: Our objective was to describe the safety and efficacy of enteral droxidopa, a norepinephrine prodrug, for intravenous (IV) vasopressor weaning in intensive care unit (ICU) patients. Methods: This was a single-center, retrospective descriptive study of adult ICU patients. Patients who received ≥ 4 consecutive doses of droxidopa for IV vasopressor weaning were included. The cessation of the IV vasopressor without re-initiation within 72 h of droxidopa initiation was the primary outcome. The adverse events assessed included hypotension, hypertension, and arrhythmias. Results: Forty-six patients were included, with a median age of 61. Forty-two patients (91%) were on midodrine at the time of droxidopa initiation. The median daily midodrine dose was 80 mg. The median time from ICU admission to droxidopa initiation was 17 days. Patients were on a median of one IV vasopressor at the time of droxidopa initiation, with norepinephrine as the most common agent (50%). The median initial daily droxidopa dose was 300 mg, with a median maximum daily dose of 900 mg. Vasopressor support was discontinued within 72 h of droxidopa initiation in 46% of patients, with a median time to IV vasopressor cessation of 3.3 days. There were no incidences of hypotension, hypertension, arrhythmias, or ICU readmissions related to droxidopa. Droxidopa was continued upon discharge in 29% of patients. Conclusions: Droxidopa may be a safe and effective option to facilitate the weaning of IV vasopressor support in patients who are refractory or intolerant to midodrine. Larger prospective studies are needed to confirm these findings.
