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
- Rarely with icterus, seizures, fever and bleeding tendency
Haematology & Biochemistry
- Increased ALT and 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
