Index of Yamamoto-Furusho et al for the Activity of Ulcerative Colitis

Description

Yamamoto-Furusho et al reported an index for describing the activity of ulcerative colitis. The authors are from Instituto Nacional de Ciencias Medicas y Nutricion Salvador Zubiran in Mexico City.

Patient selection: ulcerative colitis

Parameters:

(1) number of bloody bowel movements per day

(2) hemoglobin in g/dL

(3) serum high sensitivity CRP in mg/dL

(4) serum albumin in g/dL

(5) findings on endoscopy

(6) findings on histopathology

Parameter	Finding	Points
bloody bowel movements	none	0
	2 or 3	1
	4 to 6	2
	> 6	3
hemoglobin	> 12 g/dL	0
	10 to 12 g/dL	1
	8 to 9.9 /dL	2
	< 8 g/dL	3
serum CRP	<= 0.2 mg/dL	0
	0.21 to 0.35 mg/dL	1
	0.36 to 1.0 mg/dL	2
	> 1.0 mg/dL	3
serum albumin	>= 3.5 g/dL	0
	3.0 to 3.4 g/dL	1
	2.5 to 2.9 g/dL	2
	< 2.5 g/dL	3
endoscopic findings	normal mucosa	0
	erythema, vascular pattern decreased, mild friability	1
	marked erythema, absent vascular pattern, erosions, friable	2
	ulceration, spontaneous bleeding	3
histopathology	normal	0
	mild activity	1
	moderate activity	2
	severe activity	3

total score =

= SUM(points for all 6 parameters)

Interpretation:

• minimum score: 0

• maximum score: 16

Score	Activity
0 to 3	in remission
4 to 6	mild activity
7 to 12	moderate activity
13 to 18	severe activity
