  Purpose

This study is being conducted to develop new techniques for early diagnosis of liver disease. These techniques are: Shearwave Elastography (SWE) ultrasound and blood biomarkers.

SWE ultrasound uses high-frequency sound waves to view soft tissues such as muscles and internal organs and measure stiffness. An ultrasound creates computer images that show internal body organs, such as the liver or kidneys, more clearly than regular x-ray images.

Biomarkers are biological molecules found in the blood that provide important information about liver disease.

Primary Outcome Measures:
  • Non-invasive shearwave elastography (SWE) for detecting fibrosis in children with hepatitis [ Time Frame: One year ] [ Designated as safety issue: No ]
    Philips shearwave ultrasound elastography is a non-invasive procedure for assessing liver status. It provides a virtual biopsy by using liver stiffness data to detect fibrotic changes. It turns an invasive, painful, and expensive procedure into a simple, painless one, making it easier to monitor the 30 patients and leading to a more definitive diagnosis. A commercial US scanner (iU22, Philips Healthcare) was modified to produce shearwaves and track them.


Secondary Outcome Measures:
  • Serum Biomarker analysis [ Time Frame: One year ] [ Designated as safety issue: No ]
    Blood will be drawn at the same time the IV is placed for each of the patients the liver biopsy for the purposes of the serum biomarker study. We will study hyaluronic acid, tissue inhibitor of metalloprotease 1, collagen type IV, prolyl hydroxylase and collagen type VI due to previous reports of their biological association with advanced liver disease. Furthermore, we propose to examine the utility of putative serum markers of fibrogenesis in staging hepatic fibrosis and severity of clinical disease in pediatric viral hepatitis.


Biospecimen Retention:   Samples Without DNA
  1. Shearwave elastography is a non-invasive procedure to measurement liver tissue elasticity. Images will be obtained in the right lobe of the liver through intercostal spaces with the subject lying supine with right arm abduction. A total of 10 measurements will be obtained across the liver to obtain a more comprehensive evaluation.
  2. Biomarker Analysis

A. Blood: Blood will be drawn at the same time the IV is placed for the liver biopsy for the purposes of the serum biomarker study. If subjects return for an additional liver biopsy in the future or a standard of care visit they may be asked to provide an additional sample for biomarker analysis. Blood will be processed, aliquoted and stored by pathology.

B. Tissue: Unstained slides from pathology will be prepared from leftover tissue taken during the liver biopsy to be stained for additional biomarker analysis.

Groups/Cohorts
Subjects with Liver Fibrosis
  1. Shearwave elastography is a non-invasive procedure for assessing liver status. Measurements of liver tissue elasticity will be obtained in the right lobe of the liver by using a curvilinear transducer (C5-1, Philips Healthcare) through intercostal spaces.
  2. Biomarker Analysis

A. Blood: Blood will be drawn at the same time the IV is placed for the liver biopsy for the purposes of the serum biomarker study. If subjects return for an additional liver biopsy in the future or a standard of care visit they may be asked to provide an additional sample for biomarker analysis. Blood will be processed, aliquoted and stored by pathology.

B. Tissue: Unstained slides from pathology will be prepared from leftover tissue taken during the liver biopsy to be stained for additional biomarker analysis.

  Eligibility

Ages Eligible for Study:   up to 17 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Children will be recruited from the >2500 inpatient/outpatient referrals made to the Texas Children's Liver Center per year, of which over 5% are seen in the Texas Children's Viral Hepatitis Clinic for evaluation, treatment, and management of pediatric HBV or HCV. We will test the utility of putative serum markers of fibrosis and fibrogenesis, obtained from patients for diagnosis and prediction of the likelihood of progression to fibrosis.

Inclusion Criteria:

  • Infection with viral hepatitis B or C
  • Scheduled to have a clinically indicated liver biopsy
  • Between the ages 0-17

Exclusion Criteria:

  • N/A
