Background: This study evaluated the role of HA as a marker of liver fi brosis in patients with hepatitis C on haemodialysis. Methods: This is a cross-sectional study in which 52 patients were divided into two groups: Group 1: patients with hepatitis C and end-stage renal disease (ESRD) undergoing haemodialysis (n = 23); and Group 2: patients with hepatitis C without ESRD (n = 29). Plasma levels of HA were associated with histological data of the samples obtained by liver biopsy and classifi ed by METAVIR group scoring system. Results: Higher plasma levels were signifi cantly correlated to signifi cant liver fi brosis (METAVIR ≥ F2). In Group 1, the HA cutoff to discriminate signifi cant fi brosis was 984.8 ng/mL, with accuracy, sensitivity and specifi city of 80.8%, 83.0%, and 70.0%, respectively. In Group 2, the HA cutoff was 222.3 ng/mL, with accuracy, sensitivity and specifi city of 74.5%, 70.0%, and 94.0%, respectively. Conclusion: HA was an accurate noninvasive marker in predicting signifi cant fi brosis in patients with hepatitis C on haemodialysis.
