Q

Hepatitis A

A

Fecal-oral transmission
Mild disease
No chronic carrier
No Rx necessary, avoid ETOH

21
Q

Hepatitis B

A

Chronic carrier 5-10%

Major risk factor for liver CA if carrier

22
Q

Hepatitis C

A
Leading cause of chronic liver failure
Most common indication for transplant
Most asymptomatic
Screen with EIA, RIBA to confirm
HCV RNA establish chronicity and follow RX

Test Genotype (most type 1)

Rx: interferon+Ribaviron.
Not in psych pts, autoimmune disease, CA patients
Contraindication=Ongoing ETOH/drugs

23
Q

Alcoholic Hepatitis

A
AST > ALT (>2x)
Prolonged PT/low Albumin=poor prognosis
Vit deficiency (folate/ B's)
