Chronological age alone may not adequately reflect physiological reserve, immune competence, frailty, or vulnerability to treatment-related adverse outcomes. Immunosenescence, characterized by age-related changes in immune cell composition and chronic low-grade inflammation, may contribute to differences in both treatment effectiveness and safety among older adults receiving advanced therapies. However, prospective evidence linking clinically accessible markers of immune aging to treatment outcomes in IBD remains limited.\n\nThis prospective, multicenter observational cohort study will evaluate older adults with IBD who initiate a new advanced therapy as part of routine clinical care. Treatment selection and subsequent treatment modifications will remain entirely at the discretion of the treating clinicians and participants. The study will characterize participants using complementary domains including immune-aging markers, frailty, nutritional status, comorbidity and polypharmacy, inflammatory disease activity, and treatment exposure. Candidate immune-aging measures include the CD4\u002FCD8 ratio, lymphocyte measures, interleukin-6, neutrophil-to-lymphocyte ratio, and other routinely available inflammatory and nutritional biomarkers.\n\nThe primary analytical objective is to determine whether baseline immunosenescence and frailty phenotypes are associated with the overall balance of effectiveness and safety after initiation of advanced therapy. The study will also assess whether these measures provide prognostic information beyond conventional clinical factors such as age, disease activity, comorbidity burden, and treatment type. Additional analyses will explore heterogeneity across different mechanisms of advanced therapy, relationships between immune aging, frailty, and nutritional status, and differences between elderly-onset IBD and IBD diagnosed earlier in life but treated during older age.\n\nThe study is intended to establish a clinically applicable framework for risk stratification in older adults with IBD and to provide prospective data for future studies of individualized treatment strategies based on biological aging and vulnerability rather than chronological age alone.","Adults aged 60 years or older with Crohn disease, ulcerative colitis, or IBD-unclassified who are initiating a new advanced therapy as part of routine clinical care at participating tertiary IBD centers.
