Unmet needs in Cushing's syndrome: the patients' perspective.

BACKGROUND

Cushing's syndrome (CS) is a rare condition of chronically elevated cortisol levels resulting in diverse comorbidities, many of which endure beyond successful treatment affecting the quality of life. Few data are available concerning patients' experiences of diagnosis, care and persistent comorbidities.

OBJECTIVE

To assess CS patients' perspectives on the diagnostic and care journey to identify unmet therapeutic needs.

METHODS

A 12-item questionnaire was circulated in 2019 by the World Association for Pituitary Organisations. A parallel, 13-item questionnaire assessing physician perceptions on CS patient experiences was performed.

RESULTS

Three hundred twenty CS patients from 30 countries completed the questionnaire; 54% were aged 35-54 and 88% were female; 41% were in disease remission. The most burdensome symptom was obesity/weight gain (75%). For 49% of patients, time to diagnosis was over 2 years. Following treatment, 88.4% of patients reported ongoing symptoms including, fatigue (66.3%), muscle weakness (48.8%) and obesity/weight gain (41.9%). Comparisons with delay in diagnosis were significant for weight gain (P = 0.008) and decreased libido (P = 0.03). Forty physicians completed the parallel questionnaire which showed that generally, physicians poorly estimated the prevalence of comorbidities, particularly initial and persistent cognitive impairment. Only a minority of persistent comorbidities (occurrence in 1.3-66.3%; specialist treatment in 1.3-29.4%) were managed by specialists other than endocrinologists. 63% of patients were satisfied with treatment.

CONCLUSION

This study confirms the delay in diagnosing CS. The high prevalence of persistent comorbidities following remission and differences in perceptions of health between patients and physicians highlight a probable deficiency in effective multidisciplinary management for CS comorbidities.
