Fecal Myeloperoxidase Levels Reflect Disease Activity in Children With Crohn's Disease.

Background: Crohn's disease (CD) is a major form of inflammatory bowel disease (IBD) which has relapsing and remitting symptoms. Better ways to detect and monitor active disease are required for early diagnosis and optimal outcomes. We assessed fecal myeloperoxidase (fMPO), a neutrophil-derived enzyme that produces hypochlorous acid, as a marker of disease activity in children with CD.

Development and investigation of a non-invasive disease severity index for inflammatory bowel disease.

Introduction: The disease severity index (DSI) encapsulates the inflammatory bowel disease (IBD) burden but requires endoscopic investigations. This study developed a non-invasive DSI using faecal calprotectin (DSI-fCal) and faecal myeloperoxidase (DSI-fMPO) instead of colonoscopy.

Methods: Adults with IBD were recruited prospectively.

Comparison of Fecal Calprotectin and Myeloperoxidase in Predicting Outcomes in Inflammatory Bowel Disease.

Background: Biomarkers have been proposed as surrogate treatment targets for the management of inflammatory bowel disease (IBD); however, their relationship with IBD-related complications remains unclear. This study investigated the utility of neutrophil biomarkers fecal calprotectin (fCal) and fecal myeloperoxidase (fMPO) in predicting a complicated IBD course.

Methods: Participants with IBD were followed for 24 months to assess for a complicated IBD course (incident corticosteroid use, medication escalation for clinical disease relapse, IBD-related hospitalizations/surgeries).

The Disease Severity Index for Inflammatory Bowel Disease Is a Valid Instrument that Predicts Complicated Disease.

Background: The disease severity index (DSI) for inflammatory bowel disease (IBD) combines measures of disease phenotype, inflammatory activity, and patient-reported outcomes. We aimed to validate the DSI and assess its utility in predicting a complicated IBD course.

Methods: A multicenter cohort of adults with IBD was recruited.

The Impact of Disease Activity on Sexual and Erectile Dysfunction in Patients With Inflammatory Bowel Disease.

Background: Increased disease activity may be a risk factor for sexual dysfunction (SD) in patients with inflammatory bowel disease (IBD). This study investigated associations between objective measures of disease activity and sexual function.

Methods: Adults with IBD undergoing ileocolonoscopy were prospectively recruited.
