Abstract
This study aimed to elucidate predictors of liver fibrosis in patients with chronic hepatitis B virus (HBV) infection. Transient elastography was performed to define liver stiffness in 533 patients with chronic HBV infection (mean age ± standard deviation, 30.72 ± 0.57 years). Protein array was performed on serum samples and lysates of Huh7 cells transfected with HBV mutants; the results were confirmed by enzyme-linked immunosorbent assay. Single-nucleotide polymorphisms in the gene encoding interleukin 1β (IL-1β) were examined in patients with chronic HBV infection with and without liver fibrosis. Male sex, age ≥18 years, and serum α-fetoprotein level >3.6 ng/mL were independent predictors of a liver stiffness measurement of ≥7 kPa (P = .005, .019, and <.001, respectively). HBV e antigen (HBeAg)-negative hepatitis is associated with increased liver stiffness (P < .001). Elevation of the serum IL-1β level was demonstrated in subjects with liver fibrosis. IL-1β was upregulated in Huh7 cells transfected with HBV mutants associated with HBeAg-negative hepatitis. The AA genotype at rs16944 and the CC genotype at rs1143627 in the gene encoding IL-1β were associated with higher serum IL-1β levels and liver fibrosis. Male sex, age ≥18 years, elevated α-fetoprotein level, and HBeAg-negative hepatitis are risk factors for liver fibrosis. IL-1β is involved in the progression of liver fibrosis in subjects with HBeAg-negative hepatitis.
