Abstract:
Background: Obstructive sleep apnea (OSA) often occurs in patients with active acromegaly and improves after treatment. Less is known about the development of OSA in patients after a longer period of control treated with somatostatin analogues (SSA) and pegvisomant.
Methods: Seventy-nine patients (12 females, 17 males; age 49 +/- 14 years; body mass index 29.9 +/- 5.4 kg/m(2); IGF-1 184 +/- 73 mu g/L; disease duration 13 +/- 8 years (mean +/- standard deviation)) with wellcontrolled acromegaly treated with SSA (38%), pegvisomant (38%) or in combination (24%) who underwent ambulatory polygraphy were included in a prospective multicenter cross-sectional study.
Results: Fourteen percent had OSA (range of apnea-hypopnea index (AHI) 5 -15). Patients with OSA (AHI >= 5 vs. < 5) had a longer disease duration (16 +/- 1 vs. 12 +/- 8 years; P = 0.01) and were older (61 +/- 9 vs. 47 +/- 13 years; P = 0.037). The AHI of all patients correlated with age (P = 0.01; r = 0.44). No differences were seen in terms of BMI and Epworth sleepiness scale score. Previous transsphenoidal surgery and radiation had no impact of the detection of OSA. The duration of well-controlled acromegaly was 7 +/- 3 years.
Conclusion: OSA in patients with well-controlled acromegaly treated with SSA, pegvisomant or in combination is less frequent (14%) than previously described. Early treatment to reduce the active disease period should be aimed to prevent OSA.
