Ulcerative colitis in the elderly: clinical patterns and outcome in 51 Greek patients

In this study, the clinical characteristics and course of all patients with ulcerative colitis in whom diagnosis of the disease was made at or after the age of 60 (older group), were analyzed and compared with those of patients with ulcerative colitis in whom diagnosis of the disease was made before the age of 60 (younger group).

The older group consisted of 51 patients (28 men and 23 women; aged 64+/-3.1 years) and the younger group consisted of 362 patients (192 men and 170 women; aged 38.4+/-14.9 years). The mean follow-up times in the two groups were 9.3 and 12.6 years, respectively.

No significant differences between the two groups were found as far as the extent of the disease, the severity of the initial episode, and the outcome of the first episode of ulcerative colitis were concerned. However, significantly fewer elderly patients were operated on for their disease compared with younger patients (6.25% vs 22.3%; P = 0.0268). Although some differences in the course of the disease between elderly and younger patients were observed, such as the number of exacerbations and recurrences and the number of patients who developed colorectal cancer, these differences did not reach statistical significance.

It is concluded that ulcerative colitis in elderly Greek patients runs a rather similar course to that in younger patients. However, some unique characteristics observed in the elderly patients (lower rate of colectomy, absence of patients with colorectal cancer, and increased death rate) could be attributed either to truly different disease behavior in the elderly people or to factors directly related to their advanced age.
