Abstract: Objective To investigate the correlation between kidney injury and viral load in patients with
hepatitis C. Methods Total of 203 patients with HCV infection and 57 healthy controls in Chifeng Hospital
from June 2016 to December 2016 were randomly selected. The levels of serum urea nitrogen, creatinine
(Cr), uric acid (UA), cystatin C (CysC) and HCV RNA load were detected. Results The levels of serum
urea nitrogen and cystatin C in patients with HCV infection were higher than those of healthy controls, the
differences were statistically significant (t = 4.022, 6.555; P < 0.001). There was no significant difference
between serum Cr and UA (t = 1.535, 0.071; P = 0.546, 0.837). There was a significant negative correlation
between CysC levels and HCV RNA load in patients with HCV infection (r = -0.232, P = 0.009). Conclusions
CysC may be associated with HCV replication, combined detection of BUN, Cr and CysC can better evaluate
renal function injury in patients with HCV infection.
