Abstract
We aimed to underline the importance of serum S100B protein as a useful biochemical marker in patients with obstructive sleep apnea syndrome (OSAS).
Material and methodsForty-three newly diagnosed patients with OSAS (median apnea-hypopnea index [AHI, events/hour]: 37.5 [range 11.3–137]) and 25 subjects with AHI < 5 (median AHI: 4.4 [range 0.7–4.8]) were included in the study. Serum S100B protein level was tested in serum samples taken after polysomnography in both groups and the difference between OSAS patients and the control group regarding that level was assessed. In addition, the association of S100B protein serum level with age, body mass index, AHI, mean O2 saturation percentage during sleep, minimum O2 saturation value (%) at the end of the apneas, and the time spent at an O2 saturation less than 90% were analyzed in the OSAS patient group.
ResultsMedian serum S100B protein level was 133.7 pg/mL (range 20.97–230.70 pg/mL) in patients with OSAS and 16.1 pg/mL (range 10.1–22.9 pg/mL) in the control group (p < 0.005). Serum S100B protein level did not correlate with any studied variable (p > 0.05 for each correlation coefficient).
ConclusionsSerum S100B protein level is increased in patients with OSAS and may be a useful biochemical marker in those patients.
