Severe hypoxemia causes ATP depletion and increased adenosine production in many body tissues. Therefore we hypothesized that patients with sleep apnea and severe hypoxemia during sleep have higher adenosine production and higher plasma adenosine levels than patients without hypoxemia. Twelve patients with sleep apnea and six normal volunteers had plasma adenosine levels measured by high-performance liquid chromatography. Each patient with sleep apnea had a polysomnograph sleep study with oxyhemoglobin saturation continuously recorded. Five of 12 patients with sleep apnea had both sleep apnea and severe hypoxemia during sleep. These patients with severe nocturnal hypoxemia had significantly higher plasma adenosine levels (means +/- SD 9.7 +/- 5.5 X 10(-8) M) than either a group of six normal volunteers (3.5 +/- 0.7 X 10(-8) M) or a group of seven patients with sleep apnea without hypoxemia at night (3.1 +/- 1.5 X 10(-8) M) (P less than 0.01). In addition plasma adenosine levels were significantly correlated with two indexes of nocturnal hypoxemia (desaturation index rs = 0.79, and median oxyhemoglobin saturation during sleep rs = -0.75, P less than 0.01). Plasma adenosine markedly fell to a normal level in the only two patients with sleep apnea who had successful treatment of their multiple apneas and accompanying severe hypoxemia during sleep.
