Hepatic Disorders Flashcards
Exam 3
The liver serves several functions: What are they?
Blood storage, blood filtration, production of bilirubin, synthesis of clotting factors, removal of clotting factors
Metabolism of carbohydrates, fat, and protein
Detoxify the blood
Storage area for vitamins A, D, E, and K and iron
Hepatitis: What causes Hepatitis?
Several viruses cause hepatitis
Hepatitis: How is Hepatitis transmitted?
Fecal-oral contamination or blood and body fluid exposures
Hepatitis: How many types of autoimmune hepatitis are there?
2 types of autoimmune hepatitis
Hepatitis: Pathophysiology
Inflammation of liver cells most commonly caused by a virus that impairs its ability to function normally
Hepatitis: Pathophysiology
What does inflammation do?
This inflammation limits the ability of the liver to detox substances and
limits the production of proteins and clotting factors.
Hepatitis: Other risk factors?
Other risk factors for hepatitis include:
chronic alcohol use,
exposure of some prescriptions and over the counter medications,
as well as toxins.
In autoimmune hepatitis, what occurs? What is it classified as?
In autoimmune hepatitis, an immune system response causes inflammation in the liver, which is classified either as type one or type 2.
Pathophysiology of hepatitis
How can the virus of hepatitis be categorized? How do the categories vary?
The virus of hepatitis can be categorized according to letters ranging from A to G, which each having different incubation periods, modes of transmissions and other characteristics.
HEPATITIS- Clinical manifestations?
Abdominal pain,
irritability,
pruritus,
malaise,
fever,
nausea,
vomiting,
jaundice
HEPATITIS: What are lab abnormalities?
Elevated liver enzymes and alanine transaminase, elevated bilirubin, elevated serum ammonia, and decreased albumin
What is the most common type of viral hepatitis?
Hepatitis A is the most common Type of hepatitis
Viral hepatitis A: How is Hepatitis A primarily spread?
Is primarily spread through the oral route from food, water or shellfish that has been infected with the virus.
Viral hepatitis A: How else is Hepatitis A spread? (not primary way)
It can also be spread through close contact with infected persons, such as in households or daycare centres, with an increased incidence in unsanitary conditions.
Viral hepatitis A: Where is Hepatitis A normally found?
The hepatitis A vaccine is found on surfaces but is destroyed by cooking food for orally
Hepatitis B: How is it spread?
Is spread by blood and body fluids or secretions such as semen.
Hepatitis B: What are examples of how Hep B is spread?
The virus can be spread through the mucosa membrane or contact with infected.
Fluids during childbirth or through skin puncture with needles or other instruments.
Hepatitis B: How are patient infected with Hepatitis B? What are they considered?
Patients infected with hepatitis B have acute or chronic infections and are considered infectious as long as the antigen is present in the bloodstream.
What vaccine is required for all healthcare workers?
There is a vaccine for hepatitis B and it is required for all healthcare personnels.
Hep B: How is the vaccine administered?
This vaccine is multi. Series injection is given in. Special intervals.
Hepatitis C: What was it previously known as? How is it spread?
Previously known as non, a knobby is spread through blood and body fluids from the mother to child during childbirth.
How do a significant number of Hepatitis C cases occur?
A significant number of cases also occur through sharing contaminated needles from Ivy drug users.
What are other settings where Hep C can occur?
Other settings include tattoos or body piercing establishments.
What is the most common indication of a liver transplantation?
Hepatitis C is most common indication of a liver transplantation.
Hepatitis D: What kind of people is Hep D seen in?
Are only in people who have been infected with hepatitis B
Hepatitis D: Why is the Hep D virus only seen in people who have been infected with Hep B?
Because Hep D requires the Hep B antigen to replicate.
Hepatitis D: How is Hep D spread?
It is spread through the contact with infectious blood and most commonly found in patients who are drug users
People who receive hemodialysis or have received multiple transplants
What types of vaccine have a vaccine?
There is no vaccination for hepatitis D.
Hepatitis E: What is it caused by?
It is caused by hepatitis E virus
Hepatitis E: How is it transmitted?
Is transmitted via the fecal oral route primarily through water or contamination areas of poor sanitation.
Hepatitis G: How is it known to be transmitted?
Hepatitis G was discovered in 1996 and is known to be transmitted by infected blood or blood products.
Hepatitis G: How may is be transmitted?
It may be transmitted through sexual contact and IV drug use.
Hepatitis G: Who is at greatest risk of developing Hep G?
Patients with hemophilia or those who require blood transfusions at greatest risk.
People who have hepatitis B&C can often be infected with what?
People who have hepatitis B&C can often be infected with hepatitis G.
What are symptoms of jaundice? -
Yellowing of sclera
Yellowing of skin
Elevated bilirubin in the blood
What shows up secondary to hepatitis? Why?
Jaundice shows up secondary because of decreased expulsion of bilirubin in the stool.
There is more bilirubin circulating the body.
What are the two types of Hepatitis? (Not autoimmune)
Nonviral forms of hepatitis
Hepatitis can be acute or chronic
Types of hepatitis:
Nonviral forms of hepatitis: What is it caused by?
Caused by ingested, inhaled, or injected toxins or medications
Types of hepatitis:
Nonviral forms of hepatitis: How is it similar to viral hepatitis?
Patients with non viral forms of hepatitis have clinical presentations similar to those of viral hepatitis, such as nausea, vomiting, jaundice, anorexia, and hepatomegaly.
Types of hepatitis:
Nonviral forms of hepatitis: What does diagnosis include?
How can recovery occur?
Diagnosis includes detailed history and physical examination and a history of exposure to potential toxins.
Types of hepatitis:
Nonviral forms of hepatitis: What If it is determined that a person has been exposed to a liver toxin or a toxin is removed?
If it is determined that a person has been exposed to a liver toxin or a toxin is removed, recovery can be rapid.
Types of hepatitis:
Nonviral forms of hepatitis: What happens if there is a prolonged period between exposure to toxin and development of manifestations?
However, if there is a prolonged time period between the exposure to the toxin and the development of clinical manifestations, recovery can be prolonged.
Types of hepatitis:
What differentiates acute from chronic hepatitis?
Hepatitis can be both chronic or acute and is differentiated by the period of time.
Types of hepatitis
Hepatitis can be acute or chronic:
How long is acute hepatitis? What is the course of the infection?
Acute hepatitis infection lasts less than 6 months and most shed the virus and recover from all of their symptoms
Types of hepatitis
Hepatitis can be acute or chronic:
How long is chronic hepatitis? What is the course of the infection?
Chronic hepatitis is an infection that lasts longer than 6 months and can span the patient’s lifetime
HEPATITIS:
Hepatitis can be acute or chronic: Having a virus that is prolonged for a period of time leads to what?
Having a virus that is prolonged for a period of time increases the patience chances of developing complications such as cirrhosis, liver failure and liver cancer.
Contracting Hepatitis B or C can lead to?
Patients who contract hepatitis B and hepatitis C can develop chronic hepatitis that leads to the progression of liver damage and causes 80% of primary liver cancer.
How is the risk of liver cancer decreased in patients with chronic Hepatitis C?
In patients with chronic hepatitis C, the risk of liver cancer is decreased for the patients on anti viral therapy because this therapy prevents the virus from replicating, thus slowing the progression of liver damage.
HEPATITIS:
What is management?
Laboratory and diagnostic testing includes assessments that determine the extent of liver damage
HEPATITIS: What are medications?
Oral antiviral agents,
pegylated interferon injections, and vaccinations for hepatitis B and hepatitis A
HEPATITIS: What is surgical management of Hepatitis?
Liver transplantation (Cadaver or living donor)
HEPATITIS:
Diet and activity:
Dichromate recommendations for patients with hepatitis are similar to a healthy diet, low in fats and high in fruits and vegetables as well as whole grains.
