Oxidative stress and inflammatory profiles in obstructive sleep apnea: are short-term CPAP or aerobic exercise therapies effective?

Purpose The effects of medium to long-term continuous positive airway pressure (CPAP) or physical activity in decreasing oxidative stress, inflammatory, and cell-free DNA markers in obstructive sleep apnea (OSA) have been explored. Here we evaluate oxidative stress markers (TBARS, AOPP, SOD), proinflammatory cytokines (TNF-α, IL-1β, IL-6, IL-8), anti-inflammatory cytokines (IL-4, IL-10), and cell-free DNA levels before and after 8-week CPAP treatment or moderate-intensity aerobic training in moderate to severe OSA.
