Abstract
ObjectiveTo evaluate the clinical value of ultrasound attenuation parameters (UAP) in diagnosing the liver steatosis degree in patients with chronic liver disease, and to explore the relevant factors that affect UAP detection values.
Methods130 cases with chronic liver disease diagnosed as liver steatosis by liver biopsy during January 2014 to May 2019 were selected from the Hepatology Department of Integrated Traditional Chinese and Western Medicine of the Third Hospital of Hebei Medical University. UAP and liver stiffness (LSM) were detected by iLivTouch, and the body mass index (BMI) was calculated. Simultaneously, serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyltransferase (GGT), total bilirubin (TBil), triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL) levels and peripheral platelet (PLT) counts were measured. The correlation between UAP and liver steatosis was analyzed based on the liver histopathological results. SPSS 21.0 statistical software was used for statistical analysis. Receiver operating characteristic curve (ROC) was used to analyze the accuracy and specificity of UAP in the diagnosis of liver steatosis in patients with chronic liver disease. Spearman’s rank correlation analysis was used to study the relevant factors affecting UAP value.
ResultsThe histopathological changes of liver biopsy showed that there were 43 cases of grade F1, 47 cases of F2, 32 cases of F3 and 8 cases of F4. UAP and BMI (r = 0.363, P < 0.001), and UAP and liver steatosis degree ( r = 0.380, P < 0.001) were positively correlated. BMI and the liver steatosis degree were independent predictors of UAP value. The cut-off points for UAP to diagnose liver steatosis degree were 276 dB/m for F≥2, 288 dB/m for F≥2, 293 dB/m for F≥3, and F = 4, respectively. The sensitivity and specificity was 0.379, 0.500, 0.750, and 0.930, 0.922, 0.836, respectively.
ConclusionUltrasonic attenuation parameters cannot only determine the presence or absence of liver steatosis in patients with chronic liver disease, but also can better assess the liver steatosis degree.
