Abstract Objectives This study sought to evaluate the quality of life and the presence of psychiatric disorders in patients with sarcoidosis. Methods Data were collected from 80 consecutive outpatients with sarcoidosis presenting to the Sarcoidosis Center of the Respiratory Diseases Division at the University of Siena, Italy. Results Forty-four percent of the subjects endorsed at least one psychiatric DSM-IV axis I diagnosis. Specifically, 25% of subjects met the criteria for Major Depressive Disorder, 6.3% for Panic Disorder, 6.3% for Bipolar Disorder, 5% for Generalized Anxiety Disorder and 1.3% for Obsessive Compulsive Disorder. Statistically significant correlations were found between Forced Expiratory Volume in the first second (FEV1 ), Forced Vital Capacity (FVC) and several domains of the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) questionnaire. Subjects with multi-systemic involvement, with asthenia and with a more severe radiographic stage and subjects receiving steroids, reported a poorer quality of life. Conclusions Sarcoidosis is associated with a high rate of psychiatric comorbidity and may contribute to a poorer quality of life. A referral for a psychiatric or psychological evaluation and counseling should be considered for many of the sarcoidosis patients.
