Circulating Mitochondrial DNA in Patients in the ICU as a Marker of Mortality: Derivation and Validation

Abstract excerpt

BACKGROUND: Mitochondrial DNA (mtDNA) is a critical activator of inflammation and the innate immune system. However, mtDNA level has not been tested for its role as a biomarker in the intensive care unit (ICU). We hypothesized that circulating cell-free mtDNA levels would be associated with mortality and improve risk prediction in ICU patients. METHODS AND FINDINGS: Analyses of mtDNA levels were performed on...
