Cell-free DNA and outcome in sepsis
Severe sepsis can be a catastrophic condition that is often associated with poor outcomes. The early diagnosis and management of the condition are vital in order to improve the chances of survival. However, owing to the syndromal nature of its definition and the lack of a biomarker able to accurately confirm the condition, the diagnosis of sepsis is challenging. Even more challenging is the pre...
متن کاملCell-free plasma DNA as a predictor of outcome in severe sepsis and septic shock.
BACKGROUND Increased concentrations of cell-free DNA have been found in plasma of septic and critically ill patients. We investigated the value of plasma DNA for the prediction of intensive care unit (ICU) and hospital mortality and its association with the degree of organ dysfunction and disease severity in patients with severe sepsis. METHODS We studied 255 patients with severe sepsis or se...
متن کاملCell - free DNA: بیومارکر نوین تشخیص آزمایشگاهی
به انواع مختلف اسیدهای نوکلئیک آزاد در پلاسما شامل قطعات DNA ژنومی،DNA میتوکندریایی، DNA و mRNA های ویروسی و همچنین انواع miRNA اصطلاحا Cell–free nucleic acid گفته می شود. بخش مهمی از این اسیدهای نوکلئیک آزاد در پلاسما را Cell–free DNA (cfDNA) تشکیل می دهد. cfDNA به صورت قطعاتی با وزن مولکولی حدود KB 21-0.18 در سرم یا پلاسمای افراد سالم و افراد مبتلا به بسیاری از بیماری ها قابل تشخیص هستند. ...
متن کاملPrognostic utility and characterization of cell-free DNA in patients with severe sepsis
INTRODUCTION Although sepsis is the leading cause of death in noncoronary critically ill patients, identification of patients at high risk of death remains a challenge. In this study, we examined the incremental usefulness of adding multiple biomarkers to clinical scoring systems for predicting intensive care unit (ICU) mortality in patients with severe sepsis. METHODS This retrospective obse...
متن کاملCell-Free DNA Modulates Clot Structure and Impairs Fibrinolysis in Sepsis.
OBJECTIVES Sepsis is characterized by systemic activation of inflammation and coagulation in response to infection. In sepsis, activated neutrophils extrude neutrophil extracellular traps composed of cell-free DNA (CFDNA) that not only trap pathogens but also provide a stimulus for clot formation. Although the effect of CFDNA on coagulation has been extensively studied, much less is known about...
