Liver Disease Flashcards
Hepatitis A ; 3
Fecal and oral route
Water, sewage, food
RUQ Pain, jaundice, N,V
Hepatitis B C
Transmitted via blood, body fluids - semen, saliva
May progress to chronic states with cirrhosis and liver failure
NAFLD - Non Alcoholic Fatty Liver Disease
Fat droplets accumulate in liver
Associate with T2DM, obesity, hyperlipemia
May progress to NASH and NASH cirrhosis
Effects of acetaldehyde on brain / heart
Hyperacetaldehydemia Malfunction of brain and heart tissues
Stages of ALCHOLIC LIVER DISEASE
1- Hepatic steatosis fatty liver
2- Alcoholic hepatitis
3- Alcoholic cirrhosis
3 Mechanisms affected by alchol
1- CHO - we eat food and CHO is digested an absorbed witht he help of insulin. In liver diease/alcoholism pts don’t eat well.
2- Glycogenolysis - glycogen stores in liver are depleted
3- GNG - formation of glucose is inhibited because liver function is impaired
2 Dangerous by products of alcohol metabolism
Acetaldehyde and hydrogen
Acetaldehyde, 2
Toxic by product of alcohol metabolism
Damages mitochondria membrane and affects liver function
Tx for NAFLD
Wt loss of 3-5% improves Need 10 % weight loss for NASH Omega 3 for TG Vit e for oxidatve stress OHA diabetic for NASH
Levels of albumin in liver disease
It is normal to drop
STAGE 1 of alcoholic liver disease
Increase in fatty acid mobilization from adipose tissue
Slow of reactions requiring NAD, ratio of NADH to NAD increase; which increases TG
Asymptomatic usually
Problem with hydrogen as byproduc of alcohol
Replaces fat as fuel, therefore more fat accumulates - more fatty liver
Hyperlipidemia, Ketosis
Effects of acetaldehyde in liver
Hepatotoxicity, impacts function of liver
Decreases vitamin activation - hypovitaminia
Inflammation, necrosis
Renin angiotensin in ascites
Levels of aldosterone increase triggers resorption of sodium and water
3 main causes of ascites
Low albumin levels
Increased tissue pressure, lymphatic blockage
Renin Angiotensin mechanisms triggering more sodium and water reabsorption
GI Bleeding
If there is GI bleeding - no EN
PN is patient will be PNO for more than 5-7 days
NG used with baloon to press on bleeding vessel
Medications to stop bleeding
STAGE 2 O of alcholic disease
Alcoholic Hepatitis
Hepatomegaly
Increased ASL and ALT transaminase
Anorexia, some jaundice, coagulopathy, encelopathy, ascites
Portal Hypertension
Coagulation of abdominal vessels
Collateral circulation - esophageal varices - enlargement of veins
Foods tat are easy to swallow
STAGE 3 of alcoholic disease
Acoholic cirhosis Portal hypertension Ascites Encephalopaty GI Bleeding
Medical treatment for ascites Meds
Furosemide - Lasix
Spironolactone - Aldactone
What accumulates in ascites?
Fluid, Na, protein
In peritoneal cavity
Vitamin impacted by renin angiotensin mechanism
Vitamin K lowers
Monitor!
Hepatic Encephalopathy - Mechanism #2
Altered neurotransmitter theory
No GNG so body is using BCAA for energy
serum BCAA decreases and AAA increases
amino acid imbalance
Hepatic Encephalopathy Mechanism 1
N toxins cross brain barriers
Ammonia cant be converted into urea by the liver
