Indications for Testing

  • Assess presence of fibrosis in patients with known liver disease or newly discovered disease

Laboratory Testing

  • Serum testing (noninvasive)
    • Indirect markers
      • Main initial markers [aspartate aminotransferase (AST), alanine aminotransferase (ALT), platelet count, prothrombin time (PT)] are not useful on their own
      • Combining markers with noninvasive scans may improve sensitivity
    • Direct markers
      • Multiple biomarkers exist – most have relatively low specificity and sensitivity if used alone
        • Sensitivity and specificity based on disease process involved in fibrosis
        • No evidence to support use of collagen or metalloprotease measurements
      • Hyaluronic acid
        • Unsulfated, highly-polymerized glycosaminoglycan
        • Endogenous ligand for toll-like receptor of Kupffer cells
        • Synthesized by activated hepatic stellate cells
        • Most useful in nonalcoholic liver fibrosis
        • Negative predictive value is 93-99%
          • <55 µg/L excludes patients unlikely to have extensive fibrosis or cirrhosis
        • May avoid or postpone need for liver biopsy
        • Has been combined in panel testing with other markers in attempts to improve sensitivity (Fibrospect, HepaScore)

Histology

  • Liver biopsy (invasive)
    • Remains important in cases with diagnostic uncertainty with coexisting disorders (HIV and hepatitis C), overlapping syndromes (primary biliary cirrhosis and autoimmune hepatitis), when there is an absolute necessity for diagnosis
    • Considered gold standard for diagnosis of fibrosis
    • Recommended sample size – at least 15 mm long and containing >5 portal tracts
    • Limitations – costly, painful, subject to sampling error (identifies hepatic disease in only 65-75%), morbidity (0.3%), mortality (0.01%)

Other

  • Ultrasound – may help in diagnosis of NAFLD
  • FibroScan – measures liver stiffness in kPa (vibration controlled transient elastography)
    • Generates mild-amplitude, low-frequency elastic waves in liver (50Hz)
      • Elastic waves travel faster through stiffer tissues (fibrotic or cirrhotic)
    • Has been evaluated for fibrosis and cirrhosis assessment in chronic HBV and HCV; HIV/HCV coinfection; nonalcoholic fatty liver disease; alcohol liver disease; and biliary diseases (eg, PBC, PSC)
    • Comparison of performance to indirect markers (eg, serology tests)
      • Studies demonstrate lower and higher sensitivity results
        • Even in studies demonstrating lower sensitivity, sensitivity is comparable to indirect markers
  • Magnetic resonance elastography
    • Same principal as FibroScan
  • Acoustic radiation force impulse
    • Evaluates localized tissue displacement from acoustic pulses using B-mode ultrasonography

Chronic liver disease is a common problem worldwide.

Epidemiology

  • Prevalence
    • Chronic viral hepatitis (B or C) infection – leading cause of chronic liver disease, affects >4 million people in the U.S.
    • Alcohol-related liver disease results in >12,000 deaths annually in U.S.
  • Age – unusual in patients <40 years unless in combination with a genetic disease associated with cirrhosis
  • Sex – M>F

Etiology

Pathophysiology

  • Chronic liver inflammation leads to an increase in interstitial fibrous tissue
  • Widespread disruption and secondary attempts at repair by the liver cause irreversible histologic changes leading to cirrhosis

Clinical Presentation

  • May be asymptomatic until late-stage disease
  • Hepatocellular dysfunction – jaundice, hepatomegaly
  • Portal hypertension – varices, splenomegaly, ascites, palmar erythema, spider angiomata

Indications for Laboratory Testing

Tests generally appear in the order most useful for common clinical situations.

Hyaluronic Acid, Serum 0081138
Method: Quantitative Enzyme-Linked Immunosorbent Assay

Limitations

Results obtained with different assay methods or kits cannot be used interchangeably

Fasting specimens best, as eating slightly increases hyaluronic acid (HA)

Follow Up

If elevated may need to perform liver biopsy

Liver Fibrosis, Chronic Viral Hepatitis (Echosens FibroMeter) 2005661
Method: Quantitative Nephelometry/Quantitative Enzymatic/Quantitative Spectrophotometry/Automated Cell Count/ Electromagnetic Mechanical Clot Detection

Limitations

Results should be interpreted in conjunction with the patient’s clinical history, particularly when the rules-based system has modified the scores

Test is not validated for individuals <18 years

Assay interference (negative) may be observed when high concentrations of N-acetylcysteine (NAC) are present

Negative interference has also been reported with NAPQI (an acetaminophen metabolite), but only when concentrations are at or above those expected during acetaminophen overdose
