Abstract:

The aim of this study was to assess the association between apnea-hypopnea index (AHI) with neutrophil lymphocyte ratio (NLO) and platelet lymphocyte ratio (PLO) according to gender in patients with obstructive sleep apnea syndrome (OSAS) and to investigate whether PLO and NLO can be a predictor of disease severity before polysomnography. Material and Method: This study was designed as retrospective and cross-sectional, between March 2018 and April 2018, The patients who underwent PSG who were admitted to the Otorhinolaryngology outpatient clinic of Adana City Training and Research Hospital with the complaint of snoring and sleep apnea were evaluated. The study population was divided into four groups: (i) first group described as; AHI 0-4.9 (ii) second group described as; 5-14. 9 (iii) third group described as; AHI 15-29.9 and (iv) fourth group decribed as AHI ≥30 according to polyspmnography (PSG). Neutrophil, lymphocyte and platelet results were evaluated routinely from the blood count results. Results: Of the patients included in the study, 106 were male and 32 were female. The average age was 45.3 (43.3 for males and 50.4 for females), the average body mass index (BMI) was 30.1 (min: 19 - max: 51), the average AHI was 23.7 (min: 0.3 max: 103), the average PLO was 113.1 (male:111.2 , female: 119.5) and the average NLO was 1.93 (male: 1.99, female: 1.72 ) . In our study, the highest PLO value was found in group 2 and the highest NLO value was found in group 3. The lowest NLO and PLO values were found in group 4, unlike the results from other studies. However, no statistically significant difference was found between the groups. Conclusions: In OSAS, there is a need for more comprehensive prospective and multi-centered study to better understand AHI and NLO, PLO relationship.
