title: [Organ Manifestation and Subjective Sleep Quality in Sarcoidosis].
abstract: BACKGROUND
  Sleep disturbances are more common among sarcoidosis patients than in the general population. The influence of organ involvement on the subjective sleep quality was investigated in a large group of sarcoidosis patients.
  
  
  METHODS
  In collaboration with the German Sarcoidosis Association, 1197 sarcoidosis patients were examined with a specially developed questionnaire with the Pittsburgh sleep quality index (PSQI) integrated into it.
  
  
  RESULTS
  91 % had pulmonary involvement, 65 % extra-pulmonary sarcoidosis. In 61 %, two or more organs were involved. Subjective sleep quality in PSQI declined significantly (p < 0.001) with the increase in the number of organs involved; there was a significant increase in the prevalence of known sleep apnea (p < 0.005), restless legs syndrome (RLS), percentage of women and comorbidities (all p < 0.001). In at least 33 % of patients with bone, muscle, nerve, kidney or heart involvement, the PSQI scores were > 10.
  
  
  CONCLUSIONS
  In sarcoidosis patients with involvement of at least 2 organs, sleeping behaviour that includes RLS and sleep apnea should be evaluated.
