Abstract
Background
A large number of chronic hepatitis C patients had been successfully treated by directly acting antivirals; therefore, strategies for the long-term follow-up of these patients have to be planned based on the post-treatment fibrosis stage—the main determinant of prognosis. In this study, we aim to evaluate changes in aspartate-platelet ratio index, FIB4, and liver stiffness in chronic hepatitis C patients who achieved SVR and ended treatment more than 1 year by DAAs.
Results
One hundred chronic hepatitis C patients who achieved SVR were enrolled at a median of 16 months after the end of treatment by DAAs. According to the baseline liver stiffness, 63 and 37 patients belonged to early (F0, F1, and F2) and advanced (F3 and F4) fibrosis stages, respectively. Both groups showed a decline of the degree of liver stiffness at follow-up compared to the baseline that was statistically significant in the early fibrosis group (5.9±1.5 vs 5.4±2.2 Kpcal, p=0.04), while measurements in the advanced group were (18±8.8 vs 15.9 ± 7.8 Kpcal, p=0.07). Also, serum biomarkers of fibrosis improved in both groups, where the recorded APRI and FIB4 before and after treatment were 0.42±0.3 vs 0.24±0.1, p<0.01 and 1±0.6 vs 0.93 ±0.5, p=0.1 in the early group and 0.85 ±0.5 vs 0.4±0.2, p <0.001 and 2.9±2.3 vs 1.8±1.4, p<0.02) in the advanced group, respectively. Changes in APRI and FIB4 correlated with changes in AST and ALT, but liver stiffness changes were not affected by changes in liver enzymes.
Conclusion
Although long-term improvement of APRI, FIB4, and liver stiffness scores could be achieved in chronic HCV patients after SVR by DAAS. High measurements of liver stiffness before treatment likely persist. We recommend transient elastography as a reliable tool for fibrosis assessment post-treatment.
