==Description==

==Introduction==

'''Neutrophilic cholangiohepatitis''' is characterised by infiltration of large numbers of [[Neutrophils|neutrophils]] into portal areas of the [[Liver - Anatomy & Physiology|liver]] and into the [[Liver - Anatomy & Physiology #Hepatic Duct Systems|bile ducts]].  It results from ascending bacterial infection from the [[Small Intestine Overview - Anatomy & Physiology|small intestines]].  ''[[Escherichia coli]]'', [[:Category:Staphylococcus species|''Staphylococcus spp.'']], ''[[:Category:Streptococcus species|Streptococcus]] spp.'', ''[[:Category:Clostridium species|Clostridium spp.]]'', ''[[Bacillus species|Bacillus spp.]]'', ''[[:Category:Actinomyces|Actinomyces spp.]]'', ''Bacteroides spp'' and occasionally ''[[Salmonella|Salmonella spp.]]'' have been isolated.  Concurrent biliary tract disease are common in cats, especially [[Pancreatitis - Dog and Cat|pancreatitis]] and [[Inflammatory Bowel Disease|inflammatory bowel disease]].  Other predisposing factors include congenital or acquired abnormalities of the biliary system such as that of anatomic abnormalities of the [[Gall Bladder - Anatomy & Physiology|gall bladder]] or common bile duct, bile duct obstruction caused by inspissated bile, cholelithiasis and cholecystitis.

===History and Clinical Signs===

===History and Clinical Signs===

Acute presentation with severe illness in contrast to cats with [[Cholangitis, Lymphocytic|Lymphocytic cholangitis]] who often do not appear ill. Signs include pyrexia, depression, lethargy, abdominal pain, [[Icterus|jaundice]] and dehydration.

Acute presentation with severe illness in contrast to cats with [[Cholangitis, Lymphocytic|Lymphocytic cholangitis]] who often do not appear ill. Signs include pyrexia, depression, lethargy, abdominal pain, [[Icterus|jaundice]], dehydration ,anorexia and vomiting. If presented whilst the disease is chronic, signs will include episodic anorexia, vomiting, jaundice, weight loss and possibly hepatomegaly or ascites. Many cases will have concurrent [[IBD]].

===Laboratory Tests===

===Laboratory Tests===

Good prognosis provided the cats are treated early and appropriately.
