CPa9-HNE Can Monitor Endoscopic and Clinical Disease Activity in Ulcerative Colitis

CPa9-HNE: A neutrophil-derived fragment of calprotectin measured in serum can monitor endoscopic and clinical disease activity in ulcerative colitis
Introduction
Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) presenting in remitting ulcerations of the colonic mucosa and submucosa. Mucosal healing is therefore an important treatment target for optimal disease management. Fecal calprotectin is commonly used to monitor mucosal healing –
however, patient compliance is low due to a preference for serological markers.
In this study we aimed to investigate the association of serum calprotectin [CPa9-HNE], a non-invasive neo-epitope biomarker of true neutrophil activity, with both clinical and endoscopic disease activity in UC.

Conclusion
CPa9-HNE accurately reflected both clinical and endoscopic disease activity in ulcerative colitis, based on the UCEIS and full Mayo score. These findings highlight the potential use of CPa9-HNE as a non-invasive tool to monitor both endoscopic and clinical disease activity in UC, with the potential of guiding treatment decisions and better aligning with patient preferences.
