Leptin, Obestatin and Apelin levels in patients with obstructive sleep apnoea syndrome

Abstract

In agreement with previous investigations, we could demonstrate a difference in leptin plasma levels between healthy volunteers and patients with newly diagnosed OSAS. Apelin decreases under CPAP therapy, but not significantly. Obestatin remains unchanged after onset of CPAP. We further found a linkage between leptin plasma levels and BMI, AHI and weight in the untreated patient group.
