Abstract:

Objective

To investigate the value of fecal calprotectin(FC)in the diagnosis of patients with inflammatory bowel disease(IBD)in Jiading district of Shanghai of China.

Methods

The fecal samples of 43 subjects from March 2020 to May 2020 in North District of Shanghai Ruijin Hospital were collected and divided into two groups: IBD group(n=28)and healthy control group(n=15). Fluorescence immunochromatography was used to quantitatively detect FC concentration in feces.

Results

The FC concentration in 15 healthy subjects was 40.63 μg/g, and that in 28 patients with was 323.45 μg/g.There was a significant difference in FC concentration between IBD group and control group(P<0.05). When 60 μg/g was taken as the critical value, the sensitivity and specificity of FC to determine whether IBD was active or not were 82.14% and 86.67%, respectively.There were also significant differences in FC concentrations between active IBD patients and inactive IBD patients and healthy subjects(P<0.05).

Conclusion

FC test, as a non-invasive diagnosis and treatment method, can be used as an alternative index for endoscopic diagnosis of disease activity, which has a good application value in the diagnosis of IBD and the assessment of disease activity in Jiading district of Shanghai of China.
