Abstrakt: Objective: Hepatic venous pressure gradient (HVPG) of 6-10 mmHg has been accepted as a hemodynamic parameter of stage 1 compensated liver cirrhosis (LC). The diagnostic accuracy of HVPG in the prediction of stage 1 compensated LC has been investigated in patients with chronic hepatitis B (CHB).
Methods: A total of 219 patients with CHB who underwent HVPG and liver biopsy were enrolled. The diagnostic accuracy of two methods was compared. Risk factors associated with the diagnosis of stage 1 compensated LC on the basis of the findings of HVPG, biopsy, and both HVPG and biopsy were evaluated.
Results: The HVPG score was correlated positively with the stage of biopsy (r=0.439). The sensitivity/specificity of HVPG for predicting stage 1 compensated LC were 78/81% in 6 mmHg, respectively. A total of 57 (26%), 28 (13%), and 20 (9%) patients were diagnosed with stage 1 compensated LC on the basis of the findings of HVPG, biopsy, and both HVPG and biopsy (P>0.05), respectively. Platelet/age (-0.77-0.01×platelet+0.03×age), albumin/platelet (5.05-1.19×albumin-0.01×platelet), and platelet (0.24-0.01×platelet) were found to be risk factors (logit model) for the diagnosis of stage 1 compensated LC on the basis of the findings of HVPG, biopsy, and both HVPG and biopsy.
Conclusion: HVPG showed a positive correlation with biopsy, and platelet was found to be a common risk factor for the diagnosis of stage 1 compensated LC in patients with CHB.
