Scoring system for of chronic mucosal inflammation

Histological scoring*
1	2	3	4	5	6	7
Crypt damage	Acute inflammatory index (neutrophils/eosinophils)	Edema	Erosions/ulceration	Chronic inflammatory index (mononuclear cell infiltration)	Epithelial regeneration	Distortion/branching
intact = 0 basal 1/3 = 1 basal 2/3 = 2 entire loss = 3 Loss of crypt + epi= 4	0–4	0–4	0–4	normal distribution = 0 intermediate =1 full thickness of lymphoplasmacytosis =2	no tissue repair = 3 Surface epithelium not intact =2 Slight epithelial injury = 1 Complete regeneration or normal tissue = 0	normal crypt= 0 mild = 1 moderate = 2 severe = 3
