Pathology of the Liver Ch 10 Flashcards
lab test that, alone is nonspecific for liver disease
AST or SGOT
increase in ____ without ALT is seen with myocardial infarction, hear failure and muscle injury
AST
lab test for liver disease-if elevated probable liver disease
ALT or SGPT
found in the cells of many body tissues (will not be an answer to a question for the registry test)
LDH
lab test, produced by liver, bone, intestines, and placenta; elevated with biliary obstruction**, metastasis, abscesses, or cirrhosis
alkaline phosphatase
product of breakdown of hemoglobin in tired RBC’s, elevation results in jaudice**
bilirubin
usually seen with anemias, trauma from a hematoma, or hemorrhagic pulmonary infections
indirect bilirubin (unconjugated bilirubin)
**is usually related to obstructive jaundice from stones or neoplasm
direct bilirubin (conjugated bilirubin)
prothrombin time/partial prothrombin time
PT/PTT
increase in alk. phos. and ___ indicates a biliary obstruction
GGT
marked elevations occur with hepatocellular carcinoma and hepatoblastoma
AFP
- acquired, reversible disorder of metabolism, resulting in an accumulation of triglycerides within the hepotcytes
- fatty infiltration implies increased lipid accumulation in the hepatocytes (benign)
fatty liver
causes of fatty liver**
obesity, alcohol abuse, poorly controlled hyperlipidemia, diabetes mellitus, excess cortocosteriods, pregnancy, total parenteral hyperalimentaion (nutrition), severe hepatitis, glycogen storage disease, cystic fibrosis, pharmaceutical, chronic illness
focal areas of normal liver parenchyma within a fatty infiltrated liver
focal fatty sparing
hepatitis type spread primarily by fecal/oral contamination-virus lives in the alimentary tract
hepatitis type A
hepatitis type that exists in the bloodstream, saliva and semen/spread by infected blood via needle stick or sexual contact
greatest risk to health care professionals**
hepatitis type B
hepatitis type spread by blood/body fluids
hepatitis type C
hypoechoic, enlarged liver with heperechoic portal vein walls, thickened GB walls
acute hepatitis**
hyperechoic, small liver with decreased echogenicity of portal vein walls, ascites, 6 months of hepatic inflammation present
chronic hepatitis**
what lab values are increased in hepatitis?**
increased ALT, AST, and bilirubin (acute and chronic)
clinical findings for hepatitis**
flu-like symptoms, fatigue, abnormal liver functions test, RUQ pain
simultaneous parenchymal necrosis, regeneration and diffuse fibrosis resulting in disorganization of lobular architecture
cirrhosis
micronodular (nodules ____) most commonly the result of chronic alcohol abuse, but can be the result of nutritional deprivation, hepatitis or infection **
.1-1cm
macronodular (nodules up to 5cm) is cause by ______ or other infections
chronic viral hepatitis
recannalization of the umbilical vein is seen in _______
ligamentum teres/falciform ligament
cirrhosis increase the risk for _____
Hepatocellular carcinoma hepatoma (HCC)**
