Rise of prediagnostic molecular profiling in inflammatory bowel disease-can we close the door before the horse has bolted?

Basic sciencebiomarkerbasic sciencetranslationalepidemiology
Clinical takeawayNo clinical action yet: a mechanistic finding from preclinical studies in archived samples. Consider future biomarker panels for preclinical IBD detection.
What it foundMolecular features, including increased antimicrobial antibodies and dysregulated immune proteins, can be detected years before IBD clinical presentation.
ContextChallenges current practice by suggesting IBD has a prolonged preclinical phase with detectable molecular changes, opening potential for early intervention.
No standard claimed for this paper

Every paper is compared to the standard governing its question. This one is not: either no standard in the corpus matches it, or the comparison did not hold up on review and was withdrawn rather than published unverified. Both are logged.
