ssm predicts outcomes of cld inpatients with acute liver injury

Conditions: End Stage Liver Disease; Jaundice; Liver Dysfunction; Portal Hypertension

Summary: in this study, a single non-invasive tool, spleen stiffness measurement (ssm), was used to monitor the disease regression of inpatients with chronic liver disease (cld) and acute liver injury. the present study aimed to establish an early diagnosis warning model for acute-on-chronic liver failure (aclf) by ssm and investigate the effect of dynamic changes in ssm on the short-term prognosis (28-day, 90-day morbidity and mortality) of inpatients with cld and acute liver injury.

portal hypertension is a major complication of cirrhosis and can lead to serious clinical manifestations such as ascites, hepatic encephalopathy, variceal bleeding, etc. colecchia et al. proposed the use of spleen stiffness measurement (ssm) to dynamically monitor portal pressure and to predict the risk of oesophageal varices. studies have now demonstrated the utility of ssm in assessing portal hypertension, ruling out high-risk varices, and predicting clinical complications in cirrhotic patients. furthermore, the baveno vii consensus of portal hypertension has included ssm in its recommendations for non-invasive screening. pathogenic triggers, important clinical events (ascites, encephalopathy, etc.), and short-term prognosis in compensated advanced chronic liver disease are associated with portal pressure. exploring the relationship between portal hypertension and liver failure development would be of great clinical and scientific value. the present study is mainly based on a single non-invasive tool, ssm, to monitor the disease regression of chronic liver disease (cld) inpatients with acute liver injury, to establish an early warning model for early diagnosis of acute-on-chronic liver failure, and to investigate the effect of dynamic changes in ssm on the short-term prognosis of inpatients with cld and acute liver injury.
