Aging and exocrine pancreatic function.

In view of the limited information concerning the influence of aging on exocrine pancreatic function, the authors undertook the present study. To examine a large number of elderly persons, including people of very advanced age (80 years and over), pancreatic function was studied by using the fluorescein dilaurate test (pancreolauryl test), one of the most recent tubeless, noninvasive pancreatic function tests. Sixty healthy noninstitutionalized elderly individuals (35 women and 25 men, aged 66 to 88 years, mean 78) participated in the study. Thirty-six healthy younger subjects (16 women and 20 men, aged 21 to 57 years, mean 36) were also studied as controls. All elderly subjects showed a strictly normal fluorescein dilaurate test. No significant differences in the pancreatic function test results were observed between the elderly under 80 years old and those over 80 years old. The authors conclude that the aging process per se does not significantly affect exocrine pancreatic function and, more particularly, does not impair the digestive capacity of the elderly person.
