2243. Using Host Biomarkers and Time to Blood Culture Positivity to Predict Necessity for Echocardiogram in Patients with Staphylococcus aureus Endocarditis
Abstract:BackgroundPatients with complicated S. aureus bacteremia (SaB) require a transesophageal echocardiogram (TEE) to rule out endocarditis. Risks of TEE may exceed benefits in patients with a low pretest probability of endocarditis. Given our prior findings that endovascular bacterial burden drives elevated serum IL-10 concentrations, we hypothesize that time to positive blood culture and IL-10 serum concentrations may be used to risk stratify patients for selection of TEE. We compared time to positive blood cultu… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
