History of chronic waxing and waning low-grade illness.
 
Vague clinical signs which may include anorexia, depression, weight loss, intermittent [[Stomach and Abomasum Consequences of Gastric Disease - Pathology|vomiting]] and [[Diarrhoea|diarrhoea]], [[Icterus|jaundice]],lymphadenomegaly. Severe illness and pyrexia is less likely compared to [[Cholangitis, Neutrophilic]].

**Glucocorticoid at initial immunosuppressive dose for 6-12 weeks.
+
Glucocorticoid at initial immunosuppressive dose for 6-12 weeks. This should be tapered gradually to alternate day dosing.  However, recurrence is common following initial amelioration of clinical signs.  Response to therapy is hard to assess due to the slowly progressive nature of this disease.  A persistent rise in ALT and/or increasing total serum bilirubin indicates an inadequate control of the disease.

**It has hepatoprotective (anti-inflammatory, immunomodulatory and antifibrotic effects) properties and choleretic effect.  The latter promotes increased fluidity of biliary secretions for treating or preventing sludging.
+
Ursodeoxycholic acid may be given as it has hepatoprotective (anti-inflammatory, immunomodulatory and antifibrotic effects) properties and choleretic effect.  The latter promotes increased fluidity of biliary secretions for treating or preventing sludging. Additionally antioxidants such as S-adenosylmethionine and vitamin E can be given to counteract the potent oxidising property of bile.
*Antioxidants such as S-adenosylmethionine and vitamin E.

**These are used to counteract the potent oxidising property of bile.
