Investigation of liver fibrosis with serum biochemical parameters before treatment with direct-acting antivirals, at the end of treatment, and in the first and third year after treatment in patients with chronic hepatitis C.

Abstract

Aim of the study: In the treatment of chronic hepatitis C, the need for non-invasive methods, other than invasive methods, is increasing for the detection of fibrosis before and after treatment. In our study, we aimed to determine the changes in histological response with post-treatment biochemical scoring in patients treated with direct-acting antivirals.

Material and methods: Between June 1, 2016, and January 1, 2020, 125 patients followed up with a diagnosis of chronic hepatitis C, who presented to Haseki Training and Research Hospital, were enrolled in the study. Scores of APRI, Fibro Q, Fibrosis-4 (FIB-4) index, Doha score, Fibro alpha, and fibrosis-cirrhosis index were used to evaluate the liver fibrosis of the patients with examinations before treatment, at the end of treatment and at the 12^th week, first year, and third year after treatment. The study was conducted as a retrospective observational case series.

Results: One hundred twenty-five patients were enrolled in the study. The mean age was 55.5 ±15.9 years. Patients were divided into two groups according to their baseline FIB-4 values: cirrhotic/noncirrhotic. Seven (5.6%) patients had compensated cirrhosis; there were no decompensated cirrhotic patients. There was a statistically significant decrease in scores of APRI, FIB-4, Fibro Q, and Doha score calculated during the end-of-treatment three-year follow-up period.

Conclusions: It was shown that serum fibrosis scores, such as APRI, FIB-4, Fibro Q, and Doha score, could be used to detect fibrosis before treatment and to follow histological improvement after treatment with direct-acting antivirals (DAA) in chronic hepatitis C patients.
