Histological Injury and Its Risk Factors of HBeAg-negative Chronic Hepatitis B Virus-infected Patients with Persistently Normal Alanine Aminotransferase Levels / 医学研究杂志

ABSTRACT

Objective To investigate the histological injury as well as the risk factors for the course of HBeAg-negative chronic hep-atitis B virus( HBV)-infected patients with persistently normal alanine aminotransferase ( ALT) levels ( PNAL) . Methods Ninty four patients of HBeAg-negative chronic HBV-infected with PNAL were performed liver puncturing. The ALT, HBV markers, and liver histo-logical changes were detected. The gender, age, family history, HBV-DNA and HBsAg levels were compared between different patients with liver inflammation and fibrosis. And the Logistic model was used during the analysis of independent risk factor. Results Among 94 cases, patients with inflammatory necrosis classification≥G2 accounted for 74. 5%, fibrosis grading≥S2 accounted for 27. 7%. Patients in the group of inflammatory necrosis classification≥G2 was older than the group of < G2, and the ALT level of≥G2 group was higher, as well as a higher HBV-DNA. What is more,Patients in the group of inflammatory necrosis classification ≥G2 were mainly male, and were associated with a family history of hepatitis B. Patients in the group of fibrosis stage ≥S2 was older than < S2 group, and the ALT level of fibrosis stage ≥S2 group was higher. And those patients were often associated with a family history of hepatitis B, but there was no significant difference among the HBV-DNA level and gender constitution. HBV-DNA and family history were the independent risk fac-tors of liver inflammation necrosis≥G2, and family history was the only independent risk factor of fibrosis stage≥S2. Conclusion The patients of HBeAg-negative chronic HBV-infected with PNAL, regardless of the ALT and HBV-DNA, must have a liver biopsy. The pa-tients with high level of HBV-DNA and with a family history of hepatitis B should be performed liver puncturing accordingly.
