Utilizing Monte Carlo Simulations To Optimize Institutional Empiric Antipseudomonal Therapy, Sarah J. Tennant, Donna R. Burgess, Jeffrey M. Rybak, Craig A. Martin, David S. Burgess

Pharmacy Practice and Science Faculty Publications

Pseudomonas aeruginosa is a common pathogen implicated in nosocomial infections with increasing resistance to a limited arsenal of antibiotics. Monte Carlo simulation provides antimicrobial stewardship teams with an additional tool to guide empiric therapy. We modeled empiric therapies with antipseudomonal β-lactam antibiotic regimens to determine which were most likely to achieve probability of target attainment (PTA) of ≥90%. Microbiological data for P. aeruginosa was reviewed for 2012. Antibiotics modeled for intermittent and prolonged infusion were aztreonam, cefepime, meropenem, and piperacillin/tazobactam. Using minimum inhibitory concentrations (MICs) from institution-specific isolates, and pharmacokinetic and pharmacodynamic parameters from previously published studies, a 10,000-subject Monte …

Success With Extended-Infusion Meropenem After Recurrence Of Baclofen Pump-Related Achromobacter Xylosoxidans Meningitis In An Adolescent, Kristen R. Nichols, Chad A. Knoderer, Nicholas G. Jackson, John J. Manaloor, John C. Christenson

Scholarship and Professional Work – COPHS

A 13-year-old female experienced a recurrence of baclofen pump-related central nervous system (CNS) infection caused by Achromobacter, despite absence of retained foreign material. Due to the failure of meropenem (120 mg/kg/d in divided doses every 8 hours and infused over 30 minutes) in the initial infection, the dose was infused over 4 hours during the recurrence. Meropenem is an antibiotic for which efficacy is time dependent, and 4-hour versus 30-minute infusions have been shown to prolong the time the concentration of the antibiotic exceeds the minimum inhibitory concentration (MIC) of the organism at the site of infection (T>MIC). …

Late-Occurring Vancomycin-Associated Acute Kidney Injury In Children Receiving Prolonged Therapy, Chad A. Knoderer, Allison L. Gritzman, Kristen R. Nichols, Amy C. Wilson

Scholarship and Professional Work – COPHS

Background: Acute kidney injury (AKI) in patients receiving vancomycin has been associated with trough concentrations ≥15 mg/L and longer therapy duration. The objective of this study was to determine the incidence and factors associated with late AKI in children receiving ≥8 days of vancomycin therapy. Methods: Children aged 30 days to 17 years who were admitted to our institution and received intravenous vancomycin for at least 8 days during January to December of 2007 and 2010 and had a suspected or proven gram-positive infection were included. Late AKI was categorized as AKI occurring after the first 7 days of therapy …

Pharmacologic Activities Of 3’-Hydroxypterostilbene: Cytotoxic, Anti- Oxidant, Anti-Adipogenic, Anti-Inflammatory, Histone Deacetylase And Sirtuin 1 Inhibitory Activity, Jody K. Takemoto, Connie M. Remsberg, Neal M. Davies

Pharmacy Faculty Publications and Presentations

Purpose: Delineate the selected pharmacodynamics of a naturally occurring stilbene 3’- Hydroxypterostilbene. Objective: Characterize for the first time the pharmacodynamics bioactivity in several in-vitro assays with relevant roles in heart disease, inflammation, cancer, and diabetes etiology and pathophysiology. Methods: 3’-Hydroxypterostilbene was studied in in-vitro assays to identify possible bioactivity. Results: 3’-Hydroxypterostilbene demonstrated anti-oxidant, anti-inflammatory, cytotoxic, antiadipogenic, histone deacetylase, and sirtuin-1 inhibitory activity. Conclusions: The importance of understanding individual stilbene pharmacologic activities were delineated. Small changes in chemical structure of stilbene compounds result in significant pharmacodynamic differences.

Implementing Extended-Infusion Cefepime As Standard Of Care In A Children’S Hospital: A Prospective Descriptive Study, Kristen R. Nichols, Lauren C. Karmire, Elaine G. Cox, Michael B. Kays, Chad A. Knoderer

Scholarship and Professional Work – COPHS

Background: Extended-infusion cefepime (EIC) has been associated with decreased mortality in adults, but to our knowledge, there are no studies in children.

Objective: The objective of this study was to determine the feasibility of implementing EIC as the standard dosing strategy in a pediatric population.

Methods: This was a descriptive study of children aged 1 month to 17 years, including patients in the intensive care unit, who received cefepime after admission to a freestanding, tertiary care children’s hospital. Patients were excluded if they were admitted to the neonatal intensive care unit or received cefepime in the outpatient, …
