Association between liver fibrosis progression and endothelin-1/nitric oxide in patients with nonalcoholic fatty liver disease / 临床肝胆病杂志

ABSTRACT

Objective To investigate whether the progression of liver fibrosis affects endothelial function in patients with nonalcoholic fatty liver disease (NAFLD), and to early identify the warning of cardiovascular diseases caused by endothelial dysfunction by liver fibrosis progression. Methods A total of 280 patients who attended the outpatient service or were hospitalized in Department of Liver Disease, Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine, from April 2019 to October 2020 were enrolled, and they were diagnosed with fatty liver disease by ultrasound and met the diagnostic criteria for NAFLD. General information and related serological markers were collected and recorded. FibroTouch technique was performed for the NAFLD patients diagnosed by ultrasound to record their fat attenuation parameter (FAP) and liver stiffness measurement (LSM), and according to LSM, the patients were divided into non-progressive fibrosis group (239 patients with LSM 0.05). Further analysis of the correlation of ET-1 and NO with each index showed that ET-1 was not correlated with age, NO, ALT, AST, GGT, total cholesterol, TG, HDL-C, low-density lipoprotein cholesterol (LDL-C), FAP, and BMI ( r s =-0.017, 0.054, -0.067, -0.016, -0.031, 0.004, 0.051, -0.084, -0.030, 0.080, and 0.044, all P > 0.05), and NO was not correlated with age, ET-1, ALT, AST, GGT, total cholesterol, TG, HDL-C, LDL-C, FAP, and BMI ( r s =0.004, 0.054, 0.011, 0.052, 0.004, -0.051, -0.052, -0.012, -0.076, -0.013, and -0.021, all P > 0.05). Conclusion This study shows that liver fibrosis progression in NAFLD has no impact on ET-1 and NO, suggesting that fibrosis progression may have no influence on endothelial function.
