Grading and staging refers to a semiquantitative assessment of the necroinflammatory activity (grade) and degree of fibrosis (stage) in relation to chronic hepatitis.



Ishak modification for hepatic activity index (HAI) for scoring of necroinflammatory activity in chronic hepatitis

(A) Periportal or periseptal interface hepatitis (piecemeal necrosis)

Absent

0

Mild (focal, few portal areas)

1

Mild/moderate (focal, most portal areas)

2

Moderate (continuous around <50% of tracts or septa)

3

Severe (continuous around >50% of tracts or septa)

4

(B) Confluent necrosis

Absent

0

Focal confluent necrosis

1

Zone 3 necrosis in some areas

2

Zone 3 necrosis in most areas

3

Zone 3 necrosis+occasional portal-central (P-C) bridging

4

Zone 3 necrosis+multiple P-C bridging

5

Panacinar or multiacinar necrosis

6

(C) Focal (spotty) lytic necrosis, apoptosis and focal inflammation

Absent

0

One focus or less per times 10 objective

1

Two to four foci per times 10 objective

2

Five to ten foci per times 10 objective

3

More than ten foci per times 10 objective

4

(D) Portal inflammation

Absent

0

Mild, some or all portal areas

1

Moderate, some or all portal areas

2

Moderate/marked, all portal areas

3

Marked, all portal areas

4



Scheuer classification for grading and staging of chronic hepatitis

Grade Portal/periportal activity

None

0

Portal inflammation

1

Mild piecemeal necrosis

2

Moderate piecemeal necrosis

3

Severe piecemeal necrosis

4

Lobular activity

None

0

Inflammation but no necrosis

1

Focal necrosis or acidophil bodies

2

Severe focal cell damage

3

Damage includes bridging necrosis

4

Stage Fibrosis

None

0

Enlarged, fibrotic portal tracts

1

Periportal or portal-portal septa, but intact architecture

2

Fibrosis with architectural distortion, but no obvious cirrhosis

3

Probable or definite cirrhosis

4



Metavir classification for staging of hepatitis C liver disease


No scarring

0

Minimal scarring

1

Scarring has occurred and extends outside the areas in the liver that contains blood vessels

2

Bridging fibrosis is spreading and connecting to other areas that contain fibrosis

3

Cirrhosis or advanced scarring of the liver

4
