[Chronic inflammatory intestinal diseases in the elderly and aged]

Area of Science:

• Gastroenterology
• Geriatric Medicine
• Epidemiology

Context:

• Chronic inflammatory bowel diseases (IBD) exhibit a bimodal age incidence, with a notable second peak observed after age 60.
• Epidemiological data suggest a potential female predominance in Crohn's disease among the aged population.

Purpose:

• To elucidate the characteristics of chronic inflammatory bowel diseases in the elderly population.
• To compare the clinical course, complications, and postoperative outcomes of IBD in older versus younger patients.
• To highlight key differential diagnoses for IBD in aged individuals.

Summary:

• The age incidence curve for chronic inflammatory bowel diseases shows a bimodal pattern, with a secondary peak occurring after 60 years of age.
• While some studies indicate a female predominance in Crohn's disease of the aged, the clinical course and complications of chronic IBD do not appear to be significantly modified by advanced age.
• Postoperative recurrence of Crohn's disease may be less frequent in older patients, suggesting potential differences in disease behavior or management outcomes.

Impact:

• Findings emphasize that chronic IBD in the elderly shares similarities with younger populations regarding disease course and complications.
• Highlights the critical importance of considering ischemic bowel diseases and colonic cancer in the differential diagnosis of chronic IBD presentations in older adults.
• Informs clinical practice by suggesting potentially lower rates of postoperative Crohn's disease recurrence in the aged, warranting further investigation into underlying mechanisms and implications for surgical management.
