A

Simple steatosis

causes

Non alcoholic steatoheaptits

which further develops into

Fibrosis and cirrhosis

2
Q

Define simple steatosis

A

Infiltration of liver cells with fat cells

3
Q

Define Nonalcoholic steatoheaptits

A

liver inflammation and damage caused by a buildup of fat in the liver

A

Diabetes mellitus
Obesity
Hypertriglyceridemia
Hypertension

5

What are the other risk factors for Non alcoholic fatty liver disease

A
Age
Ethnicity
 (e.g. Hispanics)
Genetic factors
 (e.g. PNPLA3 gene)
6
Q

What imaging is sued in diagnosis Non alcoholic fatty liver disease

A

Ultrasound (Fibrocan determine how much fibrosis or fat)

MR/CT

MR spectum - see fat

What are the three biomarker used in the diagnosis of nonalcoholic fatty liver disease

A

AST/ALT ratio - see is its alcohol or not (AST.>ALT)

Enhanced Liver fibrosis pannel

Cytokertatin 18

Insulin sensitizers e.g. Metformin, Pioglitazone

Glucagon-like peptide-1 (GLP-1) analogues
e.g. Liraglutide

Farnesoid X nuclear receptor ligand
e.g. Obeticholic acid
Vitamin E
