A

NONALCOHOLIC FATTY
LIVER DISEASE (STEATOSIS)

20
Q

levels

A

T

21
Q

Diagnosis of Nonalcoholic fatty liver disease

A

★ Diagnosis made after exclusion of other causes of liver
disease
★ Ultrasound, CT*, MRI helpful in detection
★ Liver biopsy required for differentiation of NASH

22
Q

Most important risk factor for NAFLD

A

Insulin resistance
★ Metabolic syndrome
○ Increased waist circumference
○ Hypertriglyceridemia
○ Hypertension
○ Elevated fasting glucose
○ Low HDL

23
Q

Clinical findings with NAFLD

A

CLINICAL FINDINGS
Modest elevation of ALT and AST-2 to 3 times
upper limit of normal may increase to 10 times
★ AST/ALT ratio of 1 or less

24
Q

Imaging for NAFLD

A

★ Ultrasound
★ CT not much more specific and more expensive*
★ MRI allows quantification of hepatic fat-more sensitive and more expensive

25
Q

TREATMENT of NAFLD

A

★ Weight loss
★ Diet and exercise
★ Treat insulin resistance with metformin or
rosiglitazone
★ Treat hypertriglyceridemia
★ Bariatric surgery
★ Liver transplant-rising number of younger
patients receiving transplants
