[Sleep disorders in patients on a kidney transplant waiting list].

Objective: To evaluate the prevalence of sleep disorders in patients awaiting kidney transplants compared to a control group.

Patients And Methods: We carried out an observational study of 23 patients on a kidney transplant waiting list in comparison with 20 healthy volunteers matched for age, sex, and body mass index (BMI). Overnight polysomnography was performed and a diagnosis of sleep apnea-hypopnea syndrome (SAHS) established when the apnea-hypopnea index (AHI) was 10 or higher.

[Value of cardiorespiratory analysis in the diagnosis of breathing sleep disorders in patients with chronic renal failure].

Background And Objective: Prevalence of sleep apnea-hypopnea syndrome (SAHS) in end-stage renal disease (ESRD) is high and the polygraphy has not been validated as diagnostic technique in this group of patients. The objective of this study was to evaluate if only the cardiorespiratory analysis is valid for the diagnosis of SAHS.

Patients And Method: 48 patients with ESRD were studied consecutively with all-night polysomnography.

[Cost-effectiveness and degree of satisfaction with home sleep monitoring in patients with symptoms of sleep apnea].

Objective: To assess the diagnostic validity, degree of patient satisfaction, and economic cost of home sleep monitoring compared to conventional polysomnography.

Patients And Methods: Consecutive patients with symptoms indicative of sleep apnea-hypopnea syndrome (SAHS) were included. We analyzed the diagnostic yield of home sleep monitoring using the apnea-hypopnea index (AHI), number of desaturations of at least 3%, and the percentage time with arterial oxygen saturation below 90%.
