Cure8 research brief
Sarcopenia is common in Crohn's disease and is linked to worse outcomes; a simple GNRI-based prediction tool could help identify at-risk patients without routine CT scanning.
Adults with Crohn's disease, IBD clinicians, dietitians/nutritionists, and researchers interested in biomarkers for malnutrition/sarcopenia.
This retrospective study compared three nutrition-related indices (GNRI, ALI, PNI) in 333 Crohn's patients and developed a nomogram combining the GNRI with clinical factors to predict CT-defined sarcopenia. The GNRI performed well, was stable across subgroups, and the GNRI-based model showed good discrimination in internal validation.
The paper suggests the GNRI could be a noninvasive surrogate to help identify patients at higher risk of sarcopenia and guide targeted nutritional assessment and interventions. This report is grounded in the article abstract and internal validation results; Cure8 did not review the full study beyond the supplied text.
Retrospective design and internal validation only; findings are based on CT-defined sarcopenia and need external validation before changing practice.

Non-invasive biomarkers that reflect mucosal inflammation and systemic disease activity could help reduce reliance on frequent endoscopy and guide monitoring for people with Crohn’s disease or ulcerative colitis.
Non-invasive urine biomarkers could make diagnosis and disease-activity monitoring easier and less invasive for people with IBD. Identifying metabolites linked to UC activity may help tailor monitoring without frequent...
A noninvasive wearable that tracks inflammation markers could let people with IBD and their clinicians detect rising disease activity earlier and potentially act before symptoms develop. This may make monitoring less...
