Summary

Cirrhotic patients are at higher risk of sepsis due to impaired innate and adaptive immune responses. Septic complications represent a major issue in the management of cirrhotic patients, with a 1-month mortality rate of 23%, which increases to 80% at 3 months in case of associated organ failure.

Delay to treatment initiation during a septic episode may increase the risk of complications and mortality of cirrhotic patients. However, the inappropriate use of antibiotics exposes cirrhotic patients to the risk of more severe infections due to multi-resistant organisms or fungi.

The use of diagnostic markers for sepsis is limited in the context of cirrhosis because of the lack of hepatic synthesis of these markers on the one hand and non-specific inflammation related to cirrhosis on the other hand.

Therefore, it is necessary to develop new tools for the early diagnosis of sepsis and appropriate management of cirrhotic patients.

The interest of microRNAs (miRNAs) in the diagnosis and prognosis of septic shock has been reported in the general population. No studies have described circulating miRNAs or reported their interest in the diagnosis of sepsis in a population of cirrhotic patients with acute decompensation (AD).

This preliminary study of 800 circulating miRNAs will be performed in a cohort of patients with acute cirrhosis decompensation, for whom the incidence of sepsis is estimated at 40%. The aim to evaluate the interest and feasibility of a larger study on the interest of circulating miRNAs in the early diagnosis of sepsis in cirrhotic patients. The long-term objective of this study is the development of biomarkers for the early management of cirrhotic patients with sepsis and the rationalization of antibiotic use to improve their prognosis.
