ULTRASOUND ATTENUATION PARAMETER MEASURED BY 1D-TRANSIENT ELASTOGRAPHY IN PATIENTS WITH CHRONIC LIVER DISEASE

Abstract

Background: 1D Transient Elastograhy (ET) is able to determine in a non-invasive fashion the severity of hepatic fibrosis and it is also capable to estimate the degree of liver steatosis by determining the Ultrasound Attenuation Parameter (UAP).  Objectives: to correlate UAP with Body Mass Index (BMI) and severity of hepatic fibrosis. Materials and Methods: descriptive, cross-sectional study in patients attending UGH between April 2022 and August 2023 who underwent TE (iLivTouch FT-100).  BMI, Liver Stiffness Measurement (LSM, kPa) correlated with severity of fibrosis according to etiology and UAP (dB/m) were obtained. Results: 463 TE with liver fibrosis stage in all patients and BMI available in 328 (71%).

Discussion: 48% showed some degree of steatosis, of them 22,7%, 48,3% y 66,9% presented were lean, over-weighted, and obese  respectively. 50% had advanced stages of fibrosis with absence of steatosis in 53,68%, 41% of subjects on initial stages of fibrosis showed some degree of steatosis. Conclusions: UAP allowed to detect steatosis in lean subjects, also, the higher the fibrosis the lesser the severity of steatosis.
