    Abstract
  •   Objective  To investigate the virologic response to direct-acting antiviral (DAA) therapy and the changes in liver stiffness measurement (LSM), fibrosis-4 (FIB-4), and aspartate aminotransferase-to-platelet ratio index (APRI) after treatment in chronic hepatitis C (CHC) patients with different alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels at baseline in a real-world setting.  Methods  CHC patients who attended the outpatient service of Department of Infectious Diseases, Peking University First Hospital, from December 2017 to May 2020 were enrolled, and virologic response rate was calculated. The Wilcoxon rank-sum test was used to compare LSM, FIB-4, and APRI between groups at baseline and at 12 weeks after treatment, and the chi-square test was used for comparison of categorical data between groups.  Results  A total of 48 CHC patients were enrolled, among whom 33.3% had abnormal ALT or AST at baseline. Among these patients, the virologic response rate was 85.4% at week 4 of treatment and 100% at the end of treatment and at 12, 24, and 48 weeks after treatment, and there were significant changes from baseline to 12 weeks after treatment in LSM [6.1 (5.1-12.4) kPa vs 8.6 (5.7-16.9) kPa, Z=-1.676, P=0.043] and APRI [0.24(0.19-0.48) vs 0.42(0.23-1.17), Z=-2.050, P=0.027]. From baseline to 12 weeks after treatment, the patients with abnormal ALT or AST at baseline had significant changes in LSM [8.9(5.6-13.1) kPa vs 14.4(8.0-28.2) kPa, Z=-1.679, P=0.047] and APRI [0.44(0.25-0.50) vs 1.29(0.99-2.09), Z=-3.427, P=0.001].  Conclusion  CHC patients achieve a high sustained virologic response rate after DAA therapy, and the patients with abnormal ALT or AST at baseline tend to have more significant improvements in LSM and APRI than those without such abnormality.
