Inflammatory bowel disease and the elderly: a review

Area of Science:

• Gastroenterology
• Geriatrics
• Immunology

Background:

• Inflammatory bowel disease (IBD) incidence and prevalence are rising among the elderly.
• Older-onset IBD pathogenesis involves less genetic influence and more dysbiosis and immune dysregulation compared to younger patients.
• Diagnosing IBD in older adults is challenging due to symptom overlap with other common conditions.

Purpose of the Study:

• To highlight the unique aspects of IBD in the elderly population.
• To underscore the diagnostic and therapeutic challenges in older adults with IBD.
• To emphasize the need for more research on IBD in aging populations.

Main Methods:

• Review of existing literature on elderly-onset IBD.
• Analysis of clinical manifestations and pathogenetic factors in older IBD patients.
• Comparison of IBD presentation and progression in elderly versus younger cohorts.

Main Results:

• Older-onset IBD exhibits distinct clinical features and a less defined disease trajectory.
• Genetic factors play a diminished role in older individuals, with immune and microbial factors being more prominent.
• Existing IBD treatment efficacy studies predominantly exclude older adults.

Conclusions:

• The increasing elderly population and rising IBD rates necessitate greater attention to this demographic.
• Further research is crucial to understand and effectively manage IBD in older adults.
• Addressing the data gap in older IBD patients is an important clinical imperative.
