Abstract:
Objective:To explore the difference of liver inflammation and fibrosis in patients with chronic hepatitis B virus (HBV) infection and chronic hepatitis C virus (HCV) infection, and to investigate the relationship between hepatic pathology and alanine aminotransferase (ALT).
Methods:57 patients with chronic HCV infection and 346 patients with chronic HBV infection who were hospitalized at Shengjing Hospital of China Medical University from January 2012 to September 2016 were enrolled. In chronic HBV infection, including 88 cases whose ALT were more than two times of upper limited of normal (ALT≥2×ULN) and 258 cases whose ALT were less than two times of upper limited of normal (ALT < 2×ULN).All the patients were underwent liver biopsy. Chronic HBV infection (ALT≥2×ULN and ALT < 2×ULN) and chronic HCV infection were compared respectively. Statistical analyses were performed using a Univariate χ²-test and Mann–Whitney U test for comparison. Correlations between variables were analyzed using Spearman's rank correlation.
Results:In chronic HBV infection group, 169 cases (48.8%) had inflammation grade≥2 (G≥2), 98 cases (28.3%) had fibrosis stage≥2 (S≥2), 81 cases (23.4%) with G≥2 and S≥2.In the ALT < 2×ULN group, there were 109 cases (42.2%) with G≥2, 62 cases (24%) with S≥2, 49 cases (19%) with G≥2 and S≥2. In the ALT≥2×ULN group, 60 cases (68.2%) with G≥2, 35 cases (39.8%) with S≥2, 31 cases (35.2%) with G≥2 and S≥2. The grade of inflammation and fibrosis have significantly different between ALT≥2×ULN group and ALT < 2×ULN group (χ² = 17.66, χ² = 8.06, P < 0.01). In chronic HCV infection group, 47 cases (82.5%) with G≥2, 20 cases (35.1%) with S≥2, 20 cases (35.1%) with G≥2 and S≥2. ALT had no correlation with inflammation and fibrosis (P > 0.05). The grade of inflammation was significantly different between chronic HCV infection and chronic HBV infection whose ALT < 2×ULN (χ² = 30.19, P < 0.01) but the fibrosis have no difference (χ² = 2.96, P > 0.05). Compared with chronic HBV infection whose ALT≥2×ULN, both inflammation and fibrosis had no significantly different (χ² = 3.65, χ² = 0.32, P > 0.05 respectively).
Conclusion:In chronic HBV infection whose ALT < 2×ULN, about 30%-40% liver tissue with significant necroinflammation and /or fibrosis. About 80% chronic HCV infection with significant necroinflammation, and the grade of inflammation has no correlation with ALT. The grade of inflammation has significantly different between chronic HCV infection group and chronic HBV infection group whose ALT < 2×ULN.
