Hey JJ-
This is a chart, which you cant see but explains,
stage four being
cirrhosis and
stage two only being moderate fibrosis, if this is clear as mud I can find more.
Neil ******************************************************* Scoring Systems for Staging of Chronic Hepatitis
*******************************************************
Various scoring systems are used to evaluate the amount of fibrosis in chronic hepatitis.
Score Description Knodel Sciot and Desmet
(unpublished) Scheuer
0 No fibrosis No fibrosis None None
1 Mild fibrosis Fibrous portal
expansion Periportal fibrous
expansion Enlarged,fibrotic
portal tracts
2 Moderate fibrosis (blank) Porto-portal septa
(> 1 septum) Periportal or portal-portal septa,
but intact architecture
3 Severe fibrosis Bridging fibrosis
(portal-portal or
portal-central linkage Portocentral septa
(> 1 septum) Fibrosis with architectural
distortion, but no
obvious
cirrhosis
4
Cirrhosis Cirrhosis Cirrhosis Probable or definite
cirrhosis

HAI (histological activity index) by Knodell
I. Periportal +/- Bridging Necrosis [Score]
A. none [ 0]
B. mild piecemeal necrosis [1]
C. moderate piecemeal necrosis (involve less than 50% of the circumference of most portal tracts) [3]
D. marked piecemeal necrosis (involve more athan 50% of the circumference of most portal tracts) [4]
E. moderate piecemeal necrosis plus bridging necrosis plus bridging necrosis [5]
F. marked piecemeal necrosis plus bridging necrosis plus bridging necrosis [6]
G. multilobular necrosis [10]
II. Intralobular Degeneration and Focal Necrosis
A. none [0]
B. mild (acidoplhilic bodies, balooning degeneration and/or scattered foci of hepatocellular necrosis in < 1/3 of lobules or nodules) [1]
C. moderate (involvement of 1/3 ~ 2/3 of lobules or nodules) [3]
D. marked (involvement of > 2/3 of lobules or nodules) [4]
III. Portal Inflammation
A. no portal inflammation [0]
B. mild (sprinkling of inflammatory cells in < 1/3 of portal tracts) [1]
C. moderate (increased inflammatory cells in 1/3 ~ 2/3 of portal tracts) [3]
D. marked (dense packing of inflammatory cells in > 2/3 of portal tracts) [4]
IV. Fibrosis
A. no fibrosis [0]
B. fibrous portal expansion [1]
C. bridging fibrosis (portal-portal or portal-central linkage) [3]
D.
cirrhosis [4]
