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

Area of Science:

• Pediatric Gastroenterology
• Inflammatory Bowel Disease Research
• Biomarker Analysis

Background:

• Inflammatory bowel disease (IBD) management in children requires accurate assessment of disease activity.
• Standard C-reactive protein (CRP) levels are often undetectable in pediatric IBD patients, limiting its utility.
• High-sensitivity C-reactive protein (hs-CRP) is a potential alternative biomarker.

Purpose of the Study:

• To evaluate the utility of hs-CRP in assessing disease activity in pediatric IBD.
• To determine if hs-CRP can predict response to glucocorticoid treatment in pediatric IBD.
• To compare hs-CRP levels in active versus quiescent IBD and in different IBD subtypes.

Main Methods:

• Measured standard CRP and hs-CRP levels in 39 children with IBD undergoing colonoscopy.
• Assessed hs-CRP in 22 children with IBD for glucocorticoid treatment response.
• Included 33 non-IBD pediatric controls; hs-CRP was used when standard CRP was < 5 mg/L.

Main Results:

• Standard CRP was undetectable in 64% of IBD patients undergoing colonoscopy.
• hs-CRP could not differentiate active from quiescent IBD in patients with undetectable standard CRP.
• hs-CRP levels did not differ between glucocorticoid responders and non-responders.

Conclusions:

• hs-CRP measurement is not useful for assessing disease activity in pediatric IBD patients with undetectable standard CRP.
• hs-CRP does not aid in evaluating glucocorticoid treatment response in this population.
• Further research may be needed to identify reliable biomarkers for pediatric IBD activity.
