Clinical implications of ageing for the management of IBD.

As the global population ages, the number of older people (≥65 years) living with IBD is expected to increase. IBD therapeutics have advanced considerably over the past few decades with the introduction of multiple steroid-sparing agents as well as numerous clinical trials that have tested new therapeutic targets. However, the current paradigms for IBD management might not be directly translatable to older patients with IBD. Age-related factors such as immunodeficiency relative to younger patients, comorbidity, polypharmacy and diminished physical reserve directly or indirectly affect the natural history of their disease. This Review highlights how these age-associated variables can affect older patients with IBD and also illustrates the multiple gaps in our current knowledge of IBD in the elderly.
