Ongoing inflammatory responses play an important role in this association. Systemic inflammation is important in pathophysiology of OSA and its comorbidity. In this study, we aimed to evaluate the role of neutrophil-to-lymphocyte ratio (NLR) in OSA patients and comparing with other well-known inflammatory marker, C-reactive protein (CRP) along with thyroid-stimulating hormone(TSH) and body-mass index(BMI). We conducted a retrospective analysis of 162 patients with OSA and divided them into 2 categories based on apnea–hypopnea index (AHI) (< 30 and >  = 30), and recorded their leukocyte profiles, sex, age and body mass index. 80 matched healthy controls were taken. Patients were excluded if they had underlying cancer, chronic inflammatory disease, any systemic infection, uncontrolled hypertension and diabetes mellitus, a known acute coronary syndrome, valvular heart disease, renal or hepatic dysfunction. We found that N/L Ratio in severe OSA patients was significantly higher compared with mild and moderate OSA patients and healthy controls (p < 0.001). CRP levels were not different in all OSA stages (p = 0.595). We noted a significant difference in mean BMI of the two groups. In the wake of increase in prevalence of OSA in a developing country like India coupled with inadequate proportion of sleep labs, NLR is an inexpensive, easy to obtain, widely available marker of inflammation that might in combination with other markers assist in identifying patients with severe OSA.
