Fidaxomicin versus oral vancomycin for infection among patients at high risk for recurrence based on real-world experience.

Introduction: infection (CDI) is a common nosocomial infection and is associated with a high healthcare burden due to high rates of recurrence. In 2021 the IDSA/SHEA guideline update recommended fidaxomicin (FDX) as first-line therapy. Our medical center updated our institutional guidelines to follow these recommendations, prioritizing FDX use among patients at high risk for recurrent CDI (rCDI).

A Multicenter Retrospective Study Evaluating Intravenous to Oral Antibiotic Stepdown for Uncomplicated Streptococcal Bacteremia.

Background: The purpose of this study was to compare the efficacy and safety of intravenous (IV) versus oral (PO) stepdown therapy for uncomplicated streptococcal bacteremia.

Methods: This multicenter, retrospective study included adult patients with uncomplicated streptococcal bacteremia between 1 July 2019 and 1 July 2022. Patients who received IV therapy for the full treatment course were compared to patients who transitioned to PO therapy after initial IV therapy.

Objective: To review the efficacy, safety, and role of live biotherapeutic products (LBPs) in the prevention of recurrent infection (rCDI).

Data Sources: A literature search was performed using PubMed and Google Scholar (through February 2024) with search terms RBX2660, SER-109, and fecal microbiota. Other resources included abstracts presented at recent conferences, national clinical practice guidelines, and manufacturers' websites.

Microbiology of infection-related complications after transrectal ultrasound-guided prostate biopsy.

Introduction: The objective of this study was to describe the incidence, microbiology, and risk factors related to infectious complications after transrectal prostate biopsies.

Methods: This was a single-center, retrospective cohort study of patients undergoing prostate biopsies. Throughout the study period, the institutional recommendation for antibiotic prophylaxis was cephalexin and ciprofloxacin.

When is vancomycin prophylaxis necessary? Risk factors for MRSA surgical site infection.

Background: The 2022 SHEA/IDSA/APIC guidance for surgical site infection (SSI) prevention recommends reserving vancomycin prophylaxis to patients who are methicillin-resistant (MRSA) colonized. Unfortunately, vancomycin prophylaxis remains common due to the overestimation of MRSA risk and the desire to cover MRSA in patients with certain healthcare-associated characteristics. To optimize vancomycin prophylaxis, we sought to identify risk factors for MRSA SSI.

Rethinking Perioperative Antibiotic Prophylaxis for Low-Risk Head and Neck Procedures.

Objective: For true clean-contaminated head and neck procedures, the literature supports ≤24 hours of perioperative antibiotics. However, there are certain otolaryngology procedures with low surgical site infection (SSI) risk for which there is negligible benefit from antibiotic prophylaxis. The objective of this evaluation was to describe antibiotic use and adherence to evidence-based institutional guidelines in low-risk head and neck procedures.

Impact of the sequential implementation of a pharmacy-driven methicillin-resistant (MRSA) nasal-swab ordering policy and vancomycin 72-hour restriction protocol on standardized antibiotic administration ratio (SAAR) data for antibiotics used for resistant gram-positive infections.

Objective: Vancomycin is often initiated in hospitalized patients; however, it may be unnecessary or continued for longer durations than needed. Oversight of all vancomycin orders may not be feasible with widespread prescribing and strategies to enlist other clinicians to serve as stewards of vancomycin use are needed. We implemented 2 sequential interventions: a protocol in which the pharmacist orders MRSA nasal swab followed by a protocol requiring approval from pharmacists to continue vancomycin for >72 hours.

Treatment options for severe or refractory mpox virus infection in patients with advanced HIV.

The Centers for Disease Control and Prevention (CDC) published a health advisory on the occurrence of severe cases of mpox in immunocompromised patients, namely those with advanced HIV. Treatment options are limited, and very little is known about how to optimally treat patients with severe disease. Herein we describe two cases of severe mpox in Chicago in the setting of advanced HIV and provide suggested guidance for managing cases of severe disease in immunocompromised patients based available data, CDC recommendations, and our experience managing these patients.

Impact of a structured interview on beta-lactam reaction documentation quality.

Incomplete documentation of β-lactam reactions often leads to inappropriate antibiotic prescribing. The objective of this study was to evaluate the impact of a structured interview on the quality of β-lactam reaction documentation. After 203 interviews, documentation of the core components of a β-lactam reaction improved (48% vs 1%; < .

Reducing the use of empiric antibiotic therapy in COVID-19 on hospital admission.

Background: Empiric antibiotics for community acquired bacterial pneumonia (CABP) are often prescribed to patients with COVID-19, despite a low reported incidence of co-infections. Stewardship interventions targeted at facilitating appropriate antibiotic prescribing for CABP among COVID-19 patients are needed. We developed a guideline for antibiotic initiation and discontinuation for CABP in COVID-19 patients.

The effect of delays in second-dose antibiotics on patients with severe sepsis and septic shock.

Background: Early antibiotics are fundamental to sepsis management. Second-dose antibiotic delays were associated with increased mortality in a recent study. Study objectives include: 1) determine factors associated with delays in second-dose antibiotic administration; 2) evaluate if delays influence clinical outcomes.

Remdesivir Use in the Setting of Severe Renal Impairment: A Theoretical Concern or Real Risk?

Background: Remdesivir (RDV) is US FDA approved for coronavirus disease 2019 (COVID-19) but not recommended in severe renal impairment (SRI, Creatinine clearance <30mL/min or requiring renal replacement therapy). Few studies have evaluated RDV in patients with SRI.

Methods: Hospitalized patients who received RDV between 1 May 2020 and 31 October 2020 were analyzed in a retrospective chart review.

COVIDOSE: A Phase II Clinical Trial of Low-Dose Tocilizumab in the Treatment of Noncritical COVID-19 Pneumonia.

Interleukin-6 (IL-6)-mediated hyperinflammation may contribute to the mortality of coronavirus disease 2019 (COVID-19). The IL-6 receptor-blocking monoclonal antibody tocilizumab has been repurposed for COVID-19, but prospective trials and dose-finding studies in COVID-19 have not yet fully reported. We conducted a single-arm phase II trial of low-dose tocilizumab in nonintubated hospitalized adult patients with COVID-19, radiographic pulmonary infiltrate, fever, and C-reactive protein (CRP) ≥ 40 mg/L.

Investigating the impact of a β-lactam allergy label on preoperative antibiotic prophylaxis administration.

Objective: Surgical site infection (SSI) is a common postprocedure complication that may be prevented by adhering to established recommendations, including administration of preoperative antibiotic prophylaxis. Patients with a β-lactam allergy (BLA) label have an increased risk of SSI. We sought to evaluate the appropriateness of preoperative antibiotic prophylaxis in patients labeled with a BLA compared those without a BLA.

IL-6 Inhibition in Critically Ill COVID-19 Patients Is Associated With Increased Secondary Infections.

Anti-inflammatory therapies such as IL-6 inhibition have been proposed for COVID-19 in a vacuum of evidence-based treatment. However, abrogating the inflammatory response in infectious diseases may impair a desired host response and pre-dispose to secondary infections. We retrospectively reviewed the medical record of critically ill COVID-19 patients during an 8-week span and compared the prevalence of secondary infection and outcomes in patients who did and did not receive tocilizumab.

Automatic ID Consultation for Inpatients With COVID-19: Point, Counterpoint, and a Single-Center Experience.

There are many unknowns with regard to COVID-19 clinical management, including the role of Infectious Diseases Consultation (IDC). As hospitalizations for COVID-19 continue, hospitals are assessing how to optimally and efficiently manage COVID-19 inpatients. Typically, primary teams must determine when IDC is appropriate, and ID clinicians provide consultation upon request of the primary team.

IL6 inhibition in critically ill COVID-19 patients is associated with increased secondary infections.

Late onset infectious complications and safety of tocilizumab in the management of COVID-19.

Background: Tocilizumab (TCZ) has been used in the management of COVID-19-related cytokine release syndrome (CRS). Concerns exist regarding the risk of infections and drug-related toxicities. We sought to evaluate the incidence of these TCZ complications among COVID-19 patients.

COVIDOSE: Low-dose tocilizumab in the treatment of Covid-19.

Background Interleukin-6 (IL-6)-mediated hyperinflammation may contribute to the high mortality of coronavirus disease 2019 (Covid-19). Tocilizumab, an IL-6 receptor blocking monoclonal antibody, has been repurposed for Covid-19, but prospective trials and dose-finding studies in Covid-19 are lacking. Methods We conducted a phase 2 trial of low-dose tocilizumab in hospitalized adult patients with Covid-19, radiographic pulmonary infiltrate, fever, and C-reactive protein (CRP) >= 40 mg/L who did not require mechanical ventilation.

Effect of IV Push Antibiotic Administration on Antibiotic Therapy Delays in Sepsis.

Objectives: Timeliness of antibiotic administration is recognized as an important factor in reducing mortality associated with sepsis. According to guidelines, antibiotics should be administered within 1 hour of sepsis presentation and the Centers for Medicare & Medicaid Services mandates administration within 3 hours. This study evaluates the difference in time from sepsis diagnosis to first-dose completion of β-lactam antibiotics between IV push and IV piggyback administration.
