Serum wnt5a is a predictor for the prognosis of acute on chronic hepatitis B liver failure.

OBJECTIVES: To find a biomarker to predict the prognosis of acute on chronic hepatitis B liver failure (ACHBLF). METHODS: Expression gene profiles in wnt pathway were determined in serum from 63 patients with ACHBLF, 60 patients with chronic hepatitis B (CHB) and 30 healthy controls (HCs). RESULTS: Serum wnt5a concentration of 1.553 ng/ml showed a poor prognosis with a sensitivity of 69.23% and a specificity of 83.33% in ACHBLF patients. CONCLUSIONS: Serum wnt5a gene expression might be a potential biomarker for predicting the prognosis of ACHBLF.
