BACKGROUND: Aldosterone excess is hypothesized to worsen obstructive sleep apnea (OSA) symptoms by promoting peripharyngeal edema. However, the extent to which primary aldosteronism (PA), hypertension, and body mass index (BMI) influence OSA pathogenesis remains unclear. METHODS: We conducted a cross-sectional study of PA patients from our endocrine database to retrospectively evaluate OSA probability before and after adrenalectomy or medical management of PA. A control group of patients undergoing adrenalectomy for nonfunctioning benign adrenal masses was also evaluated. We categorized patients as high or low OSA probability after evaluation with the Berlin Questionnaire, a validated 10-question survey that explores sleep, fatigue, hypertension, and BMI. RESULTS: We interviewed 91 patients (83 PA patients and eight control patients). Median follow-up time was 2.6 y. The proportion of high OSA probability in all PA patients decreased from 64% to 35% after treatment for PA (mean Berlin score 1.64 versus 1.35, P < 0.001). This decline correlated with improvements in hypertension (P < 0.001) and fatigue symptoms (P = 0.03). Both surgical (n = 48; 1.69 versus 1.33, P < 0.001) and medical (n = 35; 1.57 versus 1.37, P = 0.03) treatment groups demonstrated reduced OSA probability. BMI remained unchanged after PA treatment (29.1 versus 28.6, P = nonsignificant), and the impact of treatment on OSA probability was independent of BMI. The control surgical group showed no change in OSA probability after adrenalectomy (1.25 versus 1.25, P = nonsignificant). CONCLUSIONS: Both surgical and medical treatments of PA reduce sleep apnea probability independent of BMI and are associated with improvements in hypertension and fatigue. Improved screening for PA could reduce OSA burden. Published by Elsevier Inc.
