Statins and CPAP in Adipose Tissue of OSA — SCAT-OSA  

Sleep Apnea, Obstructive Clinical Trial

Official title:
Statins and CPAP in Adipose Tissue: A Randomized Clinical Trial in Obstructive Sleep Apnea

Clinical Trial Summary

This study is aimed at examining the alterations in adipose tissue in obstructive sleep apnea (OSA) patients in response to treatment with atorvastatin in continuation with standard treatment with continuous positive airway pressure (CPAP).

Clinical Trial Description

In recent years the role adipose tissue to the development of cardiometabolic disorders has been increasingly recognized. Dysfunctional adipose tissue is an important source for systemic inflammation, AngII, and FFA, thus increasing CV risk in obese and aging populations. Even though heightened cardiovascular risk in OSA patients is acknowledged, adipose tissue from OSA patients has not been investigated. CPAP is standard therapy for OSA, but has shown mixed results for improvement of vascular function, insulin sensitivity, and BP, and does not reduce CV events and mortality, even in patients with established CV disease. Hence, eliminating IH alone may not be sufficient to repair preexisting damage; additional adjunct strategies aimed at cellular repair may be required to reduce cardiometabolic burden and CV risk. Statins have pleiotropic effects including reducing inflammation, and improving BP. The aim of this study is to examine the longitudinal changes in the cellular and molecular composition of adipose tissue in OSA subjects in response to 6 months combination therapy of CPAP and atorvastatin. We hypothesize that the combination therapy will reduce adipose tissue cellular damage (p16INK4A+γ-H2AX dual positive cells). Also, decreases in adipose tissue cellular damage will be associated with improved cardiometabolic profile. These studies will provide pivotal insights into potential therapeutic strategies which may reduce cardiometabolic burden in OSA population. ;
