[Blood uric acid levels in patients with sleep-disordered breathing].

Objective: Recurrent hypoxia associated with sleep apnea-hypopnea syndrome (SAHS) leads to an increase in the degradation of adenosine triphosphatase to xanthine and, secondarily, to an increase in uric acid concentrations. The aim of the present study was to determine whether there is a correlation between uric acid levels in peripheral blood and sleep-disordered breathing, independently of known confounding factors.

Patients And Methods: We carried out a retrospective cross-sectional study of 1135 patients evaluated for suspected SAHS.
