Можливості еластографії зсувної хвилі в діагностиці фіброзу печінки та моніторингу автоімунних захворювань печінки в дітей

Abstract

Autoimmune liver disease (ALD) in children, when not diagnosed and treated timely, are characterised by a progressive course leading to liver cirrhosis. Monitoring the progression of the disease is crucial for evaluating the effectiveness of treatment in ALD patients. We believe that the use of ultrasound elastography is not only valuable for diagnosing liver fibrosis but also for monitoring the course of ALD in children, representing a promising research method. Purpose - to assess the feasibility of using shear wave elastography for diagnosing liver fibrosis and monitoring the course of ALD in children. Materials and methods. In 108 children with ALD aged 3-18 years, examined at the Department of Pediatric Hepatology of the SI «Institute of Pediatrics, Obstetrics and Gynecology named after academician O. Lukyanova of the National Academy of Medical Sciences of Ukraine», from 2019 to 2023, ultrasound shear wave elastography (2D-SWE) parameters were evaluated before treatment (baseline) and at 6, 12, 24, and 36 months of therapy, depending on the stage of liver fibrosis determined by histological method using the Metavir scoring system (F0-F4) in all children. Statistical analysis was performed using GraphPad Prism 9 version 10.0.0. Results. The mean age of the children was 11 years (range 8-13.8 years), with 91% (n=98) having liver fibrosis stage ≥F2 according to Metavir. There was a significant correlation between complete biochemical remission and median 2D-SWE at 12, 24, and 36 months of treatment (p=0.0002; p=0.002; p=0.0004, respectively). The area under the ROC curve (AUC) for diagnosing liver fibrosis stage ≥F3 and F4 at 0, 6, 12, 24 and 36 months of treatment was 0.81; 0.78; 0.67; 0.81; 0.75 and 0.80; 0.91; 0.84; 0.89; 0.92, respectively. The optimal cutoff value for median 2D-SWE was 10.1 kPa; 8.9 kPa; 9.1 kPa; 8.9 kPa; 7.0 kPa and 14.0 kPa; 10.5 kPa; 10.2 kPa; 9.7 kPa; 8.1 kPa, respectively. Conclusions. Shear wave elastography is an effective method for diagnosing fibrosis ≥F3 and cirrhosis in children with ALD. Reduction in 2D-SWE values in children with ALD during treatment is a predictor of its effectiveness. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies.
