Hepatitis (redirected from Chronic active 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.

hep·a·ti·tis (hp-tts)

n. pl. hep·a·tit·i·des (-tt-dz)

Inflammation of the liver, caused by infectious or toxic agents and characterized by jaundice, fever, liver enlargement, and abdominal pain.

Hepatitis

An inflammation of the liver, with accompanying liver cell damage or cell death, caused most frequently by viral infection, but also by certain drugs, chemicals, or poisons. May be either acute (of limited duration) or chronic (continuing). Symptoms include jaundice, nausea, vomiting, loss of appetite, tenderness in the right upper abdomen, aching muscles, and joint pain. In severe cases, liver failure may result.

hepatitis (heˈ·p·tīˑ·tis),

n a family of infectious viral diseases characterized by inflammation of the liver.

---

hepatitis (hep´tī´tis),

n an inflammation of the liver.

hepatitis C (Hep C, non-A, non-B hepatitis),

n a type transmitted largely by blood transfusion or percutaneous inoculation, such as with in-travenous drug users sharing needles. The disease progresses to chronic hepatitis in up to 50% of the patients acutely infected.

hepatitis, chronic active,

n a hepatitis with chronic portal inflammation with regional necrosis and fibrosis, which may progress to nodular postnecrotic cirrhosis.

hepatitis, delta (Hep D),

n a particularly virulent form caused by the delta hepatitis virus in conjunction with the hepatitis B virus (HBV), which is spread by contaminated needles or by direct exposure to blood or other body fluids from infected individuals. It occurs primarily in persons who have been repeatedly exposed to the HBV either through frequent blood transfusions or intravenous drug use. It may also be spread during the birthing process.

hepatitis delta virus (HDV),

n the infectious agent that causes delta hepatitis, but only in the presence of the hepatitis B virus. The virus is usually superimposed on carriers of the hepatitis B surface antigen (HBsAg). It is also called the
delta agent.

hepatitis E (Hep E, epidemic non-A, non-B hepatitis),

n a self-limited type of hepatitis caused by the hepatitis E virus (HEV) that may occur after natural disasters because of fecal-contaminated water or food. There is currently no serologic test available.

hepatitis G,

n a viral infection of the stomach and intestines, transmitted via blood and coinfection with the hepatitis C virus. The duration of the incubation period and range of symptoms are unknown, and no vaccine is available.

hepatitis, homologous serum (homologous serum jaundice, serum hepatitis, syringe jaundice, type B hepatitis),

n a viral hepatitis clinically difficult to distinguish from epidemic infectious hepatitis. It is transmitted by human serum (that is, through parenteral injection, transfusions, lacerations). The incubation period is 40 to 90 days or longer. Principal manifestations are jaundice, gastrointestinal symptoms, anorexia, and malaise.

hepatitis, infectious (IH, type A hepatitis),

n a viral hepatitis that is frequently epidemic in nature and has an incubation period of 1 to 4 or even 7 weeks. It is usually transmitted by the virus in fecal matter but may be transmitted by human (transfusions, lacerations, needle punctures).

hepatitis, non-ABCDE,

n a viral infection of the stomach and intestines that is diagnosed by ruling out other forms of hepatitis. It may be transmitted orally, via injection, sexual contact, or fecal matter.

hepatitis, serum,

n See hepatitis, homologous serum.

hepatitis, viral,

n 1. hepatitis caused by one of three immunologically unrelated viruses: hepatitis A virus; hepatitis B virus; and non-A, non-B virus.
n 2. hepatitis caused by a viral infection, including that by Epstein-Barr virus and cytomegalovirus.

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.

copper-induced hepatitis

duck hepatitis

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.
