Summary

Sepsis is a life-threatening disease characterized by multi-organ failure due to dysregulated host response to infection, with high global mortality of 30-50%. One of the most important pathophysiologic hallmarks in sepsis is vascular endothelial injury that contributes to the severity and outcome of the syndrome. Effective treatments for endothelial cell injury in sepsis have been lacking to improve prognosis. Endothelial pyroptosis is a vital mechanism of vascular endothelial injury in sepsis; mitigation or abolishment of endothelial cell pyroptosis alleviate vascular endothelial damage and improve the prognosis of sepsis mice. Gasdermin D (GSDMD) mediated endothelial pyroptosis plays a critical role in modulating vascular endothelial injury in sepsis.

Long non-coding RNA (lncRNA), as a class of non-coding protein RNA longer than 200 kD, contributes to a variety of cell biological processes. The dysregulation of lncRNA results in the occurrence and development of tumors, diabetes, sepsis and other diseases. Therefore, we detected lncRNA and mRNA expression profile in 26 blood samples of septic patients using Arraystar LncRNA Microarray. We found lncRNA NBR2 regulates septic endothelial pyroptosis.

To assess any correlation of pyroptosis levels with relevant endothelial cell injury parameters and determine the prognostic value in septic patients. we measured the levels of pyroptosis in patients admitted to the Department of Critical Care Medicine for sepsis and investigated the correlation with related markers of endothelium injury. Furthermore, we determined the prognostic value of pyroptosis levels for the mortality of patients with sepsis.
