Antimicrobial peptide concentrations in subgroups of children with different phenotype of Crohn’s disease (CD) and controls. Results are expressed as median values and ranges

Subgroup of CD	Elafin [ng/ml]	Cathelicidin [ng/ml]	α1–3-defensins [ng/ml]	β1-defensin [pg/ml]
Inflammatory (B1)	15.6 (11.6–50.1)*	733 (429.3–1102.9)*	387 (275.1–728.5)*	201.9 (150.3–281.1)
Stricturing (B2)	9.8 (6.5–21.8)	400 (293.9–721.8)	218 (182.9–246.9)	167.5 (131.9–190.4)
Penetrating (B3)	1.46 (1.21–11.4)	323 (142.3–480.2)	243 (196.2–529.1)	152.7 (115.2–161.4)
Controls	9.8 (7.1–11.8)	198.2 (162.9–231.9)	256.4 (192.6–326.6)	126.5 (94.6–139.1)
