Noninvasive assessment of liver fibrosis in children with chronic hepatitis C: Shear wave elastography and APRI versus liver biopsy.

Objective: Hepatitis C virus (HCV) is a major cause of chronic hepatitis. Although liver histopathological examination remains the reference standard for liver fibrosis assessment, noninvasive means of assessment such as shear wave elastography (SWE) and aspartate aminotransferase-platelet ratio index (APRI) have been developed to reduce the need for biopsy. We evaluated the efficacy of SWE and APRI versus liver biopsy for liver fibrosis assessment in children with chronic HCV infection.

Methods: Fibrosis staging was performed in 46 children (35 boys, 11 girls; mean age: 15.52 ± 2.71 years) with liver biopsy-proven chronic HCV infection according to the METAVIR system. SWE was performed within 6 months of liver biopsy. APRI scores were calculated using data collected on the day of biopsy.

Results: Eighteen children had no or mild fibrosis (

Conclusions: In the clinical assessment of children, the APRI score and SWE can help differentiate between no or mild fibrosis and significant fibrosis. The routine use of SWE and APRI may help decrease the number of liver biopsies performed.
