ABSTRACT
Objective To study the correlation of fecal calprotectin and lactoferrin with intestinal mucosa lesions in Crohn′s disease (CD). Methods Eighty-eight cases of diagnosed CD patients were selected as study group and 35 irritable bowel syndrome (IBS) patients were as controls. Fecal samples of CD patients were collected in one week before colonoscopy examination and of IBS patients were collected of CD patients, CD activity index (CDAI) was calculated at same visit, and CD endoscopic index (CDEI) was calculated in the subsequent endoscopic examination. The level of fecal calprotectin and lactoferrin were tested by ELISA method. Results The median levels of facal calprotectin and lactoferrin in CD patients were 277.16 mg/kg (from 96.85 to 693.57 mg/kg) and 59.68 mg/kg (from 10.75 to 100.58 mg/kg) respectively, which were significantly higher than those of IBS patients (7.6mg/kg, from 5.54 to 32.3 mg/kg and 0.65 mg/kg from 0.23 to 4.34 mg/kg), (Z=-8.301 and -7.986, respectively both P =0.000). There were no significant difference of calprotectin and lactoferrin level between CD patients with colon pathological changes and without colon pathological changes (Z=-0.424 and -0.699,P=0.672 and 0.485, respectively). There was no significant difference of calprotectin and lacoferrin level between remission and active periods in CD patients (Z=-1.491 and -1.075, P=0.136 and 0.283, respectively). The median values of calprotectin and lactoferrin of patients in moderate and severe active period judged under endoscopy were 663.11 mg/kg (from 263.45 to 2015.63 mg/kg) and 105.64 mg/kg (from 56.52 to 187.44) mg/kg respectively, in mild active period were 344.54 mg/kg (from 132.03 to 722.67 mg/kg) and 86.68 mg/kg (from 21.07 to 100.55 mg/kg) accordingly, and in remission period were 133.94 mg/kg (from 60.54 to 583.33 mg/kg) and 45.31 mg/kg (from 7.59 to 48.31 mg/kg, respectively). Both calprotectin and lactoferrin levels were significantly higher in active period than in remission period (χ2=10.63 and 8.18, while, P=0.005 and 0.017, respectively). Conclusions The level of fecal calprotectin and lactoferrin can reflect the pathological changes and severity of the intestinal mucosa.
