Abstract

Aim: To investigate the effect of concomitant chronic obstructive pulmonary disease (COPD) on obstructive sleep apnea syndrome (OSAS) severity and sleep structure

Material and Method: The files of 874 OSAS patients diagnosed in our sleep laboratory between January 2005 – January 2010 were retrospectively analysed. Polysomnography was performed with Sleep Screen - Viasys device and scorring was done according to the criteria of Rech-Schaffen Kales. Chi-square and student's t-test was used in statistical analysis.

Results: Of 874 OSAS cases, mean age was 49.1±10.7 and 602 (68.9%) were male, 272 (31.1%) were female. The severity of OSAS was mild in 235 (26.9%), moderate in 224 (25.6%) and severe in 415 (47.5%). In 91 (10.4%) patients there was Overlap Syndrome (OSAS+COPD). Overlap Syndrome (OS) was seen 12.5% of male patients while OS was in only 4.4% of female patients (p<0.001). There was no statistically significant relation between OS and severity of OSAS (p=0.199). Again, OS and pure OSAS patients showed no statistically significant difference regarding BMI, AHI, AI, ODI, sleep stages, sleep efficiency an minimum saturation (p>0.05). Mean age of OS patients was significantly higher when compared to pure OSAS patients (53.6 vs. 48.7; p<0.001).

Conclusion: COPD has no effect on OSAS severity and sleep structure. COPD is more frequent in male and older OSAS patients as if in community.
