Abstract

Context

Psychiatric symptoms are common in Cushing’s disease (CD) and seem only partly reversible following treatment.

Objective

To investigate drug dispenses associated to psychiatric morbidity in CD patients before treatment and during long-term follow-up.

Design

Nationwide longitudinal register-based study.

Setting

University Hospitals in Sweden.

Subjects

CD patients diagnosed between 1990 and 2018 (N=372) were identified in the Swedish Pituitary Register. Longitudinal data was collected from 5 years before, at diagnosis and during follow-up. Four matched controls per patient were included. Cross-sectional subgroup analysis of 76 patients in sustained remission was also performed.

Main outcome measures

Data from the Swedish Prescribed Drug Register and the Patient Register.

Results

In the 5-year period before, and at diagnosis, use of antidepressants (OR 2.2[95%CI 1.3-3.7] and 2.3[1.6-3.5]), anxiolytics (2.9[1.6-5.3] and 3.9[2.3-6.6]) and sleeping pills (2.1[1.2-3.7] and 3.8[2.4-5.9]) was more common in CD than controls. ORs remained elevated at 5-year follow-up for antidepressants (2.4[1.5-3.9]) and sleeping pills (3.1[1.9-5.3]). Proportions of CD patients using antidepressants (26%) and sleeping pills (22%) were unchanged at diagnosis and 5-year follow-up, whereas drugs for hypertension and diabetes decreased. Patients in sustained remission for median 9.3 years (IQR 8.1-10.4) had higher use of antidepressants (OR 2.0[1.1-3.8]) and sleeping pills (2.4[1.3-4.7]), but not of drugs for hypertension.

Conclusions

Increased use of psychotropic drugs in CD was observed before diagnosis and remained elevated regardless of remission status, suggesting persisting negative effects on mental health. The study highlights the importance of early diagnosis of CD, and the need for long-term monitoring of mental health.
