Viral Hepatitis

Hepatitis ABC(DE)s

100

This virus requires HBsAg (hepatitis B surface antigen) for replication

Hepatitis D

200

Chronic hepatitis develops in 85% of individuals with this virus, if left untreated

Hepatitis C

300

This is the only partially double stranded DNA virus

Hepatitis B

400

This virus NEVER becomes chronic

Hepatitis A

500

These 2 viruses are generally transmitted enterally

Hepatitis A and E

Degree in Hepatitis, with Distinction

100

The time threshold that generally distinguishes acute hepatitis from chronic

6 months

200

Elevated ALTs, high HBV DNA, and horizontal transmission are what make this phase of chronic HBV distinct

Immune active/clearance phase

300

This phase of chronic HBV infection is distinguished by normal ALTs and high HBV DNA

Immune tolerant phase

400

Hepatitis A falls under this classification

Picornavirus

500

These are the 2 main categories of antiviral agents that can provide viral cure in hepatitis C

protease inhibitors and polymerase inhibitors

Labs

100

These labs often exceed 1000 U/L in acute hepatitis

serum aminotransferases: ASTs and ALTs

200

This is the FIRST serologic marker of acute Hepatitis B infection

hepatitis B surface antigen, or HBsAg

300

This is the serologic marker of acute hepatitis A infection

Hepatitis A IgM antibody, or Anti-HAV IgM

400

These 2 lab features are generally seen with chronic hepatitis

hyperbilirubinemia and hypoalbuminemia

500

This is the earliest marker of acute Hepatitis C infection

HCV RNA
