Risk factors and prognostic model for HBV-related subacute liver failure

Area of Science:

• Hepatology
• Virology
• Clinical Medicine

Background:

• Chronic hepatitis B virus (HBV) infection can lead to subacute liver failure with a poor prognosis.
• Accurate prognostication is crucial for patient management and organ allocation in HBV-related liver failure.

Purpose of the Study:

• To identify risk factors for mortality in patients with HBV-related subacute liver failure.
• To develop and validate a novel risk prediction model for HBV-related subacute liver failure.

Main Methods:

• A cohort of 192 patients with HBV-related subacute liver failure was analyzed.
• Binary logistic regression identified prognostic factors, and a risk model was developed.
• The predictive performance of the model was evaluated using receiver operating characteristic (ROC) curves.

Main Results:

• Age, hepatic encephalopathy, infection, ascites, Model for End-Stage Liver Disease (MELD) score, international normalized ratio (INR), and total cholesterol were significant independent prognostic factors.
• The newly developed risk model demonstrated superior predictive value (AUC=0.94) compared to the MELD score (AUC=0.82).
• The risk model achieved higher sensitivity (91.1%) in predicting patient mortality than the MELD score (58.2%).

Conclusions:

• Age, hepatic encephalopathy, infection, ascites, MELD score, INR, and total cholesterol are independent predictors of mortality in HBV-related subacute liver failure.
• The established prognostic model offers enhanced predictive accuracy for patient outcomes.
• This risk model can aid in clinical decision-making and resource allocation for patients with HBV-related subacute liver failure.
