[Relationship between liver pathology and clinical characters in HBV carriers]

To study the relationship between liver pathology and clinical characters of chronic HBV carriers.

Analyze the age, sex, grade of liver inflammation and stage of liver fibrosis among patients with chronic HBV carriers (n = 58) and non-active HBsAg carriers (n = 32), and compare the grade of liver inflammation and stage of liver fibrosis in different groups according to age, ALT levels and with/without HBeAg. The data was processed by using t test or Chi-square test for statistical analysis, respectively.

(1) No differences existed in gender composition ratio between chronic HBV carriers and non-active HBsAg carriers. However, the ages of non-active HBsAg carriers group (35.2+/-7.6) were much older than that of the HBV carriers group (24.7+/-4.8) (t = 2.576, P = 0.017). (2) The stage of liver fibrosis in non-active HBsAg carriers group was more aggravated than that of the chronic HBV carriers group (Chi-square = 23.231, P less than 0.01), whereas no significant differences existed between these 2 groups (Chi-square = 0.058, P = 0.972). (3) As to the grade of liver inflammation and the stage of liver fibrosis, significant differences existed between the groups with higher level of serum ALT (20-40 U/L) and lower level ( is less than or equal to 20 U/L) (Chi-square = 7.827, P = 0.008; Chi-square = 14.303, P = 0.001), and similar results also existed between elder group (more than 40) and younger group (is less than or equal to 40) (Chi-square = 10.949, P = 0.001; Chi-square = 21.271, P less than 0.01); (4) Among the chronic HBV carriers, significant differences existed in grade of liver inflammation between groups with HBeAg positive and negative patients (Chi-square = 10.275, P = 0.002), and the latter was more aggravated; however, there was no difference in stage of liver fibrosis between them (Chi-square test = 3.457, P = 0.178).

Liver histopathology can be recommended to guide the clinical diagnosis and treatment, especially for the chronic HBV carriers, with elder age, ALT close to normal and HBeAg negative.
