Value of transient ultrasonic elastography for evaluating the liver fibrosis and liver function in patients with drug-induced liver injury

Objective: To study the value of transient ultrasonic elastography for evaluating the liver fibrosis and liver function in patients with drug-induced liver injury. Methods: A total of 68 patients with drug-induced liver injury who were treated in our hospital between January 2016 and May 2017 were selected as drug-induced liver injury group, and 50 healthy volunteers who received physical examination in our hospital during the same period were selected as normal control group. The liver transient ultrasonic elastography parameter Stiffness levels as well as serum liver fibrosis index and liver function index contents of two groups of subjects were detected. Pearson test was used to evaluate the correlation of Stiffness levels with liver fibrosis and liver function damage degree in patients with drug-induced liver injury. Results: Stiffness level in drug-induced liver injury group was higher than that in normal control group; serum liver fibrosis indexes HA, LN, CⅣ, PⅢNP and CG contents were higher than those of normal control group; serum liver function indexes ALT, AST, ALP, STB and γ-GT contents were higher than those of normal control group. Conclusion: Transient ultrasonic elastography parameter Stiffness levels increase in patients with drug-induced liver injury, and the specific levels are consistent with the liver fibrosis and liver function damage degree, and can be used as the objective means to evaluate the disease severity
