cholangiolitic hepatitis

hepatitis /hep·a·ti·tis/ (hep″ah-ti´tis) pl. hepati´tides   Inflammation of the liver.

---

hepatitis A  a self-limited viral disease of worldwide distribution, usually transmitted by oral ingestion of infected material but sometimes transmitted parenterally; most cases are clinically inapparent or have mild flu-like symptoms; any jaundice is mild.

anicteric hepatitis  viral hepatitis without jaundice.

hepatitis B  an acute viral disease transmitted primarily parenterally, but also orally, by intimate personal contact, and from mother to neonate. Prodromal symptoms of fever, malaise, anorexia, nausea, and vomiting decline with the onset of clinical jaundice, angioedema, urticarial skin lesions, and arthritis. After 3 to 4 months most patients recover completely, but some may become carriers or remain ill chronically.

hepatitis C  a viral disease caused by the hepatitis C virus, commonly occurring after transfusion or parenteral drug abuse; it frequently progresses to a chronic form that is usually asymptomatic but that may involve cirrhosis.

cholangiolitic hepatitis  cholestatic h. (1).

cholestatic hepatitis 

1. inflammation of the bile ducts of the liver associated with obstructive jaundice.

2. hepatic inflammation and cholestasis resulting from reaction to drugs such as estrogens or chlorpromazines.

hepatitis D , delta hepatitis infection with hepatitis D virus, occurring either simultaneously with or as a superinfection in hepatitis B, whose severity it may increase.

hepatitis E  a type transmitted by the oral-fecal route, usually via contaminated water; chronic infection does not occur but acute infection may be fatal in pregnant women.

enterically transmitted non-A, non-B hepatitis  (ET-NANB) h. E.

hepatitis G  a post-transfusion disease caused by hepatitis G virus, ranging from asymptomatic infection to fulminant hepatitis.

infectious hepatitis  h. A.

infectious necrotic hepatitis  black disease.

lupoid hepatitis  chronic active hepatitis with autoimmune manifestations.

neonatal hepatitis  hepatitis of uncertain etiology occurring soon after birth and marked by prolonged persistent jaundice that may progress to cirrhosis.

non-A, non-B hepatitis  a syndrome of acute viral hepatitis occurring without the serologic markers of hepatitis A or B, including hepatitis C and hepatitis E.

posttransfusion hepatitis  viral hepatitis, now primarily hepatitis C, transmitted via transfusion of blood or blood products, especially multiple pooled donor products such as clotting factor concentrates.

serum hepatitis  h. B.

transfusion hepatitis  posttransfusion h.

viral hepatitis  h. A, h. B, h. C, h. D, and h. E.

Hepatitis with inflammatory changes around the small bile ducts, producing obstructive jaundice.

hepatitis

inflammation of the liver which may be toxic or infectious in origin; characterized by signs due to diffuse injury to the liver. See also liver dysfunction. There are a number of etiologically specific hepatitides which are listed under their individual headings. They are avian vibrionic hepatitis, infectious canine hepatitis (see below), infectious necrotic hepatitis, duck hepatitis, turkey hepatitis, inclusion body hepatitis, mouse hepatitis, postvaccinal hepatitis, toxemic jaundice, and those caused by fasciola and fascioloides, cysticercus, and plant toxins including pyrrolizidine alkaloids, sporidesmin, aflatoxin. See also hepatosis dietetica.

hepatitis A, B, C, D and E viruses

causes of hepatitis in humans and some nonhuman primates.

avian vibrionic hepatitis

a disease of domesticated poultry which has disappeared from those areas in the USA which were its sole habitat. Vibrio-like organisms were isolated from the outbreaks which occurred.

cholangiolitic hepatitis

see cholangiohepatitis.

chronic active hepatitis

a chronic inflammatory liver disease in humans, probably of several types with different causes, but with distinctive histopathological features of piecemeal necrosis, bridging fibrosis and active cirrhosis. A similar, but not identical disease of unknown etiology has been described in dogs.

gosling hepatitis

see goose hepatitis.

infectious canine hepatitis

an acute, highly contagious disease, occurring mainly in young dogs, caused by canine adenovirus type 1. Many dogs experience subclinical infections. Those with clinical signs show fever, depression, vomiting and abdominal pain. The course is short and in severe cases death occurs within a few days. Peracute infections occur in very young puppies. Mild infections may cause only vague signs of malaise and anorexia and many cases are not diagnosed. Dogs recovering from infection sometimes develop corneal edema ('blue eye'). A chronic hepatitis is reported as an occasional sequela. The disease can be prevented by vaccination.

mouse hepatitis

a coronavirus disease which causes heavy losses in baby mice. It is characterized by tremor, jaundice and hemoglobinuria.

mycotic hepatitis

commonly caused in cattle by extension from mycotic rumenitis due to lactic acid indigestion and damage to ruminal epithelium.

necrotic hepatitis

see infectious necrotic hepatitis.

porcine hepatitis E virus

an enteric virus of pigs related to human hepatitis E that is not known to be pathogenic.

toxipathic hepatitis

hepatitis caused by toxins, especially ingested plant toxins, e.g. some pyrrolizidine alkaloids, sporidesmin, aflatoxin.

trophopathic hepatitis

turkey hepatitis

hepatitis X

a hepatoxic disease of dogs and pigs caused by aflatoxins. See also mycotoxicosis.
