Comparative Efficacy of Liver Fibrosis and Steatosis Assessment With Fibroscan and iLivTouch

Not Applicable

Completed

• Conditions: Liver Steatoses; Liver Fibrosis; Chronic Liver Disease
• Interventions: Diagnostic Test: iLivTouch

• Registration Number: NCT05224037
• Lead Sponsor: Federal State Budgetary Scientific Institution "Federal Research Centre of Nutrition, Biotechnology

Brief Summary

This study is aimed to compare the results and operating characteristics of liver stiffness measurement with the use of Fibroscan (EchoSens, France) and iLivTouch (Wuxi Hisky Medical Technologies Co., China) in patients with chronic liver diseases.

Detailed Description

This is prospective comparative trial to assess diagnostic characteristics of non-invasive methods of liver fibrosis and steatosis assessment based on the measurement of liver stiffness. The null hypothesis is that novel device, iLivTouch FT100/FT200 and standard probe allows to obtain similar results of liver stiffness and controlled attenuation parameter compared to FibroScan 530 and probes M+ and XL+ in patients with chronic liver diseases. According to the study protocol, standard examination will be performed to eligible subjects on the same day with the use of both devices. At least 10 measurements will be performed with the use of each device to each subject after overnight fasting. The medians of liver stiffness and controlled attenuation parameter measurements, their interquartile range, success rate of measurements and related interpretations of the results (grades of liver fibrosis and steatosis) will be compared. To assess the variability of the results, demographic data (age, biological sex, ethnicity) will be collected; weight and height of the subjects will be measured on the day of examination. Medical history of the subjects will be examined to extract data, confirming the presence of chronic liver diseases and ensure eligibility.

Inclusion Criteria

• willingness to participate on the basis of the signed informed consent form;
• availability of the medical records

Exclusion Criteria
