Alcoholic and fatty liver disease Flashcards
Describe findings that may be seen on a liver biopsy in alcoholic liver disease
fatty liver
hepatitis
cirrhosis
What is NAFLD?
macrosteatosis in >5% hepatocytes in the absence of ETOH use
(corollary is alcoholic fatty liver)
What is NASH?
macrosteatosis, hepatocellular ballooning, lobular inflammation, often with perisinusoidal fibrosis in the absence of ETOH use
(corollary is alcoholic steatohepatitis)
What is cryptogenic cirrhosis
liver is not fatty so etiology is hard to identify
________ is the second leading cause of indication for liver transplantation
alcoholic liver disease
first is HCV, declining with better treatment
List factors associated with development of alcoholic liver disease
dose of EtOH
gender (women at higher risk of disease with the same dose of alcohol)
Co-morbid HBV, HCV, hemochromatosis, a1 antitrypsin deficiency
Inherited propensity- PNPLA3
Alcoholic and non-alcoholic liver disease appear to share a common genetic cause:
PNPLA3- fatty liver deposition and fibrosis, both alcohol mediated and non-alcoholic liver damage
What is the link between alcohol use, the gut microbiome, and ALD/NAFLD?
Gut microbiome appears to influence obesity
Chronic ethanol leads to leaky gut, increased translocation of bacterial products, induction of cytokines, oxidative stress
What screening questions can be used to assess for high risk drinking?
Cutdown,
Anger,
Guilt,
Eye-openers
If yes to 2+ need to follow up with more questions
What factors increase the likelihood of alcoholic relapse?
Social isolation
lack of insight into addiction
history of many failed attempts at rehabilitation
Psychiatric co-morbidities
Vitamin ____ improves some aspects of liver histology in NAFLD/NASH
E
_________ is the key change in treating NAFLD/NASH
weight loss
impacts Type II DM, obstructive sleep apnea, HTN
Weight loss from bariatric surgery improves steatosis, but its effect on _________ is uncertain
liver fibrosis
Alcoholic liver disease is a consequence of the effect of alcohol on the gut microbiome interacting with the _______ immune system
innate
