High-sensitivity C-reactive protein in paediatric inflammatory bowel disease

Table 4 The median (range) levels of inflammatory markers and histology score and their correlation with the CRP levels in 39 paediatric patients with IBD

	Median (range)	Correlation with CRP
Inflammatory markers
Calprotectin (n = 35)	690 μg/g (14-4400)	0.488b
ESR (n = 37)	18 mm/h (2-97)	0.618d
WBC (n = 38)	7.6 E9/L (3.2-17.4)	-0.011
Histology score
Ileum (n = 29)1	0 (0-15)	0.475a
Caecum (n = 38)	4 (0-14)	-0.036
Ascendens (n = 34)	4.5 (0-13)	-0.198
Transversum (n = 36)	6 (0-15)	-0.158
Descendens (n = 39)	6 (0-15)	-0.077
Sigma (n = 35)	5 (0-14)	-0.014
Rectum (n = 38)	5.5 (0-14)	-0.051
Total colon (n = 32)	30 (0-74)	-0.083

¹The histology score of the ileum was positive in only one UC patient (with backwash ileitis), all the other positive scores are from CD patients.

^aP < 0.05,

^bP < 0.01,

^dP < 0.001. ESR: Erythrocyte sedimentation rate; WBC: White blood cell count.
