Hizli O, Cayir S, Coluk Y, et al. - Researchers sought to determine if and how severity of obstructive sleep apnea was related to the markers of inflammation as fibrinogen to albumin ratio and C-reactive protein to albumin ratio among 126 patients admitted to sleep disorders outpatient clinic. Four groups were formed by reference to the apnea–hypopnea index (mild-moderate-severe sleep apnea and control group). The groups were examined to ascertain the difference of white blood cell, fibrinogen to albumin ratio, C-reactive protein to albumin ratio, neutrophil to lymphocyte ratio, platelet to lymphocyte ratio, and hemoglobin. In four groups, fibrinogen to albumin ratio and C-reactive protein to albumin ratio differed significantly. Findings indicate that inflammation may be predicted by higher fibrinogen to albumin ratio and C-reactive protein to albumin ratio in patients suffering from moderate-to-severe sleep apnea.
