Description

Chronic hepatitis is an inflammatory-necrotising disease of at least 6 months duration. It predominantly consists of lymphocytic-plasmacytic inflammatory infiltration. A number of causes include:

  • Copper accumulation
  • Drugs
  • Infections

Diagnosis

Clinical Signs

These include

  • lethargy, weakness, anorexia and weight loss
  • vomiting and diarrhoea
  • polyuria and polydipsia
  • ascites
  • and rarely icterus, seizures, fever and bleeding disthesis

Laboratory tests

Biochemistry

  • Increased alanine aminotransferase (ALT) and alkaline phosphatase (ALP). However these may not be incrased if end-stage cirrhosis is reached.
  • Hypoalbuminaemia
  • Decreased urea
  • Increased bile acids

Imaging

Biopsy

This is required for definitive diagnosis. Histology reveals lymphoplasmacellular inflammation and necrosis of the hepatocytes adjacent to the portal tracts.


Treatment

  • Glucocorticoids at 1-2 mg/kg/day PO. Taper down with improved clinical signs and normal liver enzymes values
  • Ursodeoxycholic acid at 15mg/kg PO SID
  • Antioxidants
  • Copper chelation with Penicillamine or Zinc if copper exceeds 2000ppm

Prognosis
