AIMS: To correlate cirrhosis histology and Laennec fibrosis scoring with portal pressure, as determined by hepatic venous pressure gradient (HVPG).
METHODS AND RESULTS: One hundred and four patients with biopsy-proven cirrhosis and known HVPG were included in the study. Semiquantitative scoring of 12 histological parameters and quantitative assessment by morphometry for septal thickness and nodule diameter and image analysis for fibrosis were performed. Laennec histological subgrading and clinical staging of cirrhosis were also performed. There were significant positive correlations between HVPG and Laennec histological grade of cirrhosis (P < 0.001), micronodularity (P < 0.001), the presence of thick fibrous septa (P = 0.015), the amount of collagen in the space of Disse (P < 0.001), and the extent of fibrosis by image analysis (P = 0.003). Multivariate analysis, to predict high HVPG (≥16 mmHg), showed that degree of collagen in the space of Disse [P = 0.007, odds ratio (OR) 19.3], histological grade of cirrhosis (P = 0.017, OR 3.9) and micronodularity (P = 0.02, OR 3.5) independently predicted high HVPG.
CONCLUSIONS: Histological subclassification of cirrhosis, collagen in the space of Disse and micronodularity are independent predictors of high portal pressure. The Laennec histological subclassification of cirrhosis correlates well with clinical severity of cirrhosis, and can provide useful prognostic information.
