High prevalence of sleep disorders in hemodialyzed patients requiring parathyroidectomy.
OBJECTIVE
Although there has been contrasting evidence for a causative role of parathyroid hormone (PTH) in sleep disorders in patients on maintenance hemodialysis, a recent study disclosed the possibility that this role might exist at least in patients requiring parathyroidectomy because of failure of medical therapy. The present study was devised to assess a possible difference in sleep disorders of patients on hemodialysis needing parathyroidectomy and those in whom medical therapy controlled hyperparathyroidism.


METHODS
To this end, a group of 22 patients requiring parathyroidectomy were studied by means of a sleep questionnaire, along with a group of 44 patients matched for age, gender, body weight, and duration of dialytic treatment.


RESULTS
Patients requiring parathyroidectomy slept fewer hours (P < .001), had a higher prevalence of sleep disorders (P < .001), and were more often insomniac (P < .001).


CONCLUSIONS
This study indicates that patients on hemodialysis requiring parathyroidectomy for intractable hyperparathyroidism comprise a good model for investigating the causative role of PTH on disordered sleep, and that these patients have very poor sleep. These data support recent findings on the prevalence of sleep disorders in dialyzed patients with insuppressible hyperparathyroidism.
