© 2014 by the Endocrine Society.Design and Patients: Morbidly obese patients (n = 41) were divided into those whose apneahypoapnea index (AHI) was more or less than the median value and on the presence of OSA [OSA and no OSA (nOSA) groups]. We studied the antioxidant function of HDL and measured serum paraoxonase 1 (PON1) activity, TNFα, and intercellular adhesion molecule 1 (ICAM-1) levels in these patients. In a subset of 19 patients, we immunostained gluteal sc adipose tissue (SAT) for TNFα, macrophages, and measured adipocyte size.Results: HDL lipid peroxide levels were higher and serum PON1 activity was lower in the high AHI group vs the low AHI group (P
