OBJECTIVE: This study aims to investigate the relationship between platelet count and mean platelet volume (MPV) with obstructive sleep apnea syndrome (OSAS). METHODS: This retrospective study included 417 OSAS patients (284 males, 133 females; mean age 47.9±10.0; range 23 to 75 years) who were performed polisomnography (PSG) in our clinic between January 2013 and December 2014. Patients were divided into two groups according to apnea-hipopnea index (AHI). Apnea-hipopnea index <5 was assumed as normal, while AHI ≥5 was assumed as OSAS. Platelet count and MPV values of group with normal AHI and group with OSAS were statistically compared. Apnea-hipopnea index, REM AHI, non-REM AHI, minimum oxygen saturation, and duration of oxygen saturation remaining below 90% were statistically compared with platelet count and MPV. RESULTS: The mean of platelet count in non-OSAS and OSAS groups were 262.31±65.78 and 252.77±61.86, respectively, with no statistically significant difference between the groups. Mean platelet volume in non-OSAS and OSAS groups were 9.56±1.88 and 9.71±1.57, respectively; however, the difference was not statistically significant. Platelet count increased statistically significantly as AHI, REM AHI, non-REM AHI, and minimum oxygen saturation parameters got impaired. CONCLUSION: As PSG parameters get impaired, platelet count increases in OSAS patients.
