This prospective study aims to determine the relationship between the EASIX score and mortality and prognosis in sepsis.

Sepsis is a life-threatening condition characterized by a dysregulated host response to infection, leading to organ dysfunction. Despite advancements in medicine, sepsis remains a significant cause of death worldwide. An international study showed that 48.9 million sepsis cases were diagnosed in 195 countries between 1990 and 2017, resulting in 11 million deaths. Recent studies have demonstrated that early diagnosis and treatment reduce sepsis mortality. Therefore, research has focused on identifying biomarkers that aid in early diagnosis and prognosis.

The Endothelial Activation and Stress Index (EASIX) was first defined by Luft et al. as a biomarker reflecting endothelial damage. Calculated using readily available laboratory parameters-serum lactate dehydrogenase (LDH) level (U/L) x creatinine level (mg/dL) / platelet count (10⁹/L)-it has been commonly used to predict mortality and prognosis in hematological malignancies. Recently, its application in predicting sepsis mortality and prognosis has gained attention, although only limited retrospective studies have been published.
