Cushing’s Syndrome in the Elderly

Abstract

Objective

To evaluate whether age-related differences exist in clinical characteristics, diagnostic approach and management strategies in patients with Cushing’s syndrome included in the European Registry on Cushing’s Syndrome (ERCUSYN).

Design

Cohort study.

Methods

We analyzed 1791 patients with CS, of whom 1234 (69%) had pituitary-dependent CS (PIT-CS), 450 (25%) adrenal-dependent CS (ADR-CS) and 107 (6%) had an ectopic source (ECT-CS). According to the WHO criteria, 1616 patients (90.2%) were classified as younger (<65 years) and 175 (9.8%) as older (>65 years).

Results

Older patients were more frequently males and had a lower BMI and waist circumference as compared with the younger. Older patients also had a lower prevalence of skin alterations, depression, hair loss, hirsutism and reduced libido, but a higher prevalence of muscle weakness, diabetes, hypertension, cardiovascular disease, venous thromboembolism and bone fractures than younger patients, regardless of sex (p<0.01 for all comparisons). Measurement of UFC supported the diagnosis of CS less frequently in older patients as compared with the younger (p<0.05). An extra-sellar macroadenoma (macrocorticotropinoma with extrasellar extension) was more common in older PIT-CS patients than in the younger (p<0.01). Older PIT-CS patients more frequently received cortisol-lowering medications and radiotherapy as a first-line treatment, whereas surgery was the preferred approach in the younger (p<0.01 for all comparisons). When transsphenoidal surgery was performed, the remission rate was lower in the elderly as compared with their younger counterpart (p<0.05).

Conclusions

Older CS patients lack several typical symptoms of hypercortisolism, present with more comorbidities regardless of sex, and are more often conservatively treated.
