However, it is uncertain whether in combination they promote a higher inflammatory response and greater risk of cardiovascular events than each condition alone.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>To investigate whether the presence of PLMS is associated with increased inflammation in patients suspected of having OSA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In 342 patients who underwent polysomnography to diagnose OSA, plasma C-reactive protein (CRP) and fibrinogen levels were measured.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Measurements and Main Results<\/jats:title>\n                    <jats:p>OSA was found in 254 patients, with 46 also having PLMS. Among the 88 patients who did not have OSA, 8 had PLMS. Plasma CRP and fibrinogen levels in the group with both PLMS and OSA were higher than in patients with neither OSA nor PLMS and in patients with OSA only (CRP: 0.20 \u00b1 0.48 vs. 0.09 \u00b1 0.15 vs. 0.13 \u00b1 0.18 mg\/dl, P = 0.03; fibrinogen: 298.2 \u00b1 76.1 vs. 269.0 \u00b1 57.1 vs. 270.0 \u00b1 52.6 mg\/dl, P &amp;lt; 0.01). Multivariate analysis showed that the presence of PLMS was associated with higher plasma CRP levels (\u03b2 = 0.1401, P &amp;lt; 0.01) and fibrinogen levels (\u03b2 = 0.1359, P = 0.01) independently from other clinical variables such as body mass index and the severity of OSA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>PLMS were positively associated with plasma CRP and fibrinogen levels in patients suspected of having OSA.
