Also known as suppurative cholangitis, exudative cholangitis/cholangiohepatitis and acute cholangitis/cholangiohepatitis.
Signalment
More common in cats than in dogs. Cats of all breeds and ages can be affected, but often young to middle-aged cats. Male cats are more at risk.
Aetiology and Pathogenesis
Neutrophilic cholangitis/cholangiohepatitis results from asecending bacterial infection from the small intestines. Escherichia coli, Staphylococcus spp., Streptococcus spp., Clostridium spp., Bacillus, Actinomyces, Bacteroides and occasionally Salmonella spp. have been isolated. Concurrent biliary tract disease are common in cats, especially pancreatits and inflammatory bowel diesease. Other predisposing factors include bile duct obstruction, cholelithiasis, cholecystitis.
Diagnosis
- Clinical Signs
Acute presentation with pyrexia, abdominal pain, lethargy, jaundice.
- Haematology & Biochemistry
Increased segmented and band neutrophils. Increased ALT and total bilirubin concentration
- Imaaging
A coarse or nodular texture to the liver on ultrasonography. More chronic cases may have dilation of the biliary tract.
- Cytology and Culture
Bile samples for cytology is needed for a definitive diagnosis. Histopathology of the liver alone is not adequate as the disease tend to be confied to the bialiary tract and pathology of the liver can be non speciic and mild. Cytology shows bacteria and neutrophils. Culture and sensitivity should be performed for appropriate choice of antibiotics.
