Blood proteomic signatures associated with disease activity in Inflammatory Bowel Diseases.
Background and aims: Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), remain heterogeneous disorders with variable response to biologics. Post-operative recurrence in CD is common despite surgery and prophylactic biotherapies. Understanding the inflammatory mediators associated with recurrence and treatment response could pave the way for personalized strategies.
Methods: We analyzed serum inflammatory protein signatures using proteomics in two prospective cohorts. The REMIND cohort included post-operative CD patients undergoing ileocecal resection with endoscopic assessment at 6 months (M6). Serum samples were collected at surgery and six months later. The ELYP cohort consisted of active IBD patients starting new biotherapies (anti-TNF, ustekinumab, or vedolizumab). Serum samples were collected pre- and post-treatment (Weeks 14 and 52).
Results: In the REMIND cohort, proteomic analysis revealed elevated levels of IFN-γ, CXCL9, and MMP-10 in patients with recurrence, with concentrations associated with recurrence severity. Preoperative MMP-10 levels predicted severe recurrence (AUC = 0.70). Under biotherapies, treatment-specific proteins were associated with recurrence: CXCL9 for anti-TNF and OSM/TGFα modules for ustekinumab. In the ELYP cohort, IFN-γ and CXCL9 were significantly elevated in CD compared to UC and associated with disease activity. Early response to anti-TNF treatment (Week 14) was associated with reductions in CXCL9, MMP-10, and OSM, while deep remission (Week 52) correlated with decreases in CXCL9 and OSM.
Conclusion: Our findings reveal inflammatory blood proteomic signatures associated with post-operative recurrence and biologic treatment failure in IBD. Several key biomarkers were identified. These results support the rationale for personalized approaches, including combination therapies targeting multiple pathways.ClincialTrials.gov number, NCT02693340 and NCT02693340.
