Cure8 research brief
Sarcopenia or low muscle mass may be linked with worse endoscopic healing and reduced durability of biologic therapy in IBD, particularly Crohn's disease, which could matter for prognosis and treatment planning if confirmed.
Clinicians, researchers, and adult patients with Crohn's disease or IBD who follow nutrition/body-composition issues or are interested in factors that might influence biologic treatment response.
The review pooled observational studies up to April 2025 and found wide variation in how sarcopenia was defined and measured (different imaging methods and muscle metrics).
Because studies were small, heterogeneous, and mostly observational, the review emphasizes that these associations do not prove sarcopenia causes worse outcomes — it may instead reflect more severe inflammation, malnutrition, or advanced disease. This review is hypothesis-generating rather than practice-changing.
It does not support routine sarcopenia screening for treatment decisions in IBD at present, but it highlights an area for better-designed prospective studies and standardized assessments.
The review is PROSPERO-registered and synthesizes observational studies through April 2025, but heterogeneity in definitions, imaging modalities, and outcomes means findings are hypothesis-generating and do not support routine clinical use of sarcopenia assessments for decision-making.

FAP appears linked to both inflammation and fibrosis in IBD; distinguishing cellular versus extracellular FAP might help develop or validate fibrosis biomarkers that detect fibrostenotic disease.
Fatigue is a common, burdensome symptom in Crohn's disease and hard to treat. This study links fatigue severity to differences in brain resting-state connectivity, suggesting brain–gut interactions may play a role.
This paper suggests that epithelial barrier structure and function may be altered in very early onset pediatric IBD. That could help researchers study disease mechanisms and eventually guide targeted therapies for...
