Introduction: There is little information on whether direct-acting antiviral (DAA) treatment can improve liver fibrosis or change glucose and lipid profile in patients with chronic hepatitis C (CHC). We aimed to evaluate the impact of sustained virologic response (SVR) on liver stiffness, glucose and lipid levels.
Methods: 445 monoinfected CHC patients started treatment with interferon-free DAA therapy from January 2015 to February 2017. Transient elastography (TE), fibrosis scores, glucose and lipid levels were analyzed at baseline and 48 weeks post-treatment (SVR48).
Results: The SVR rate was 97.7%. Finally, we evaluated 369 patients who achieved SVR and had reliable TE measurements. Median liver stiffness significantly decreased from 9.3 (IQR 7.3-14.3)kPa at baseline to 6.4 (IQR 4.9-8.9) at SVR48 (p<0.0001). 54.7% of the cohort presented fibrosis regression. Median FIB4 score regressed from 2.0 (IQR 1.1-3.3) to 1.3 (IQR 0.9-2.0) (p<0.0001). Median APRI and Forns values significantly decreased from 0.9 (IQR 0.5-1.7) to 0.3 (IQR 0.2-0.4) and from 6.2 (5.0-7.5) to 4.9 (IQR 3.8-5.9) (p<0.001), respectively. Mean levels of total cholesterol and LDL-C increased from 172mg/dL and 101.5mg/dL to 191mg/dL and 117.5mg/dL (p<0.0001), respectively. In the sub-group of patients with pre-diabetes or diabetes, mean glucose levels decreased from 142.7mg/dL at baseline to 127.2mg/dL at SVR48 (p<0.001).
Discussion: SVR reduces liver stiffness based on TE and fibrosis scores, in patients treated with DAA. Our results show elevated total cholesterol and LDL-C and decreased glucose levels at SVR48.
