Introduction: Obesity is generally associated with a chronic state of subclinical inflammation. The assessment of the inflammatory status is routinely made by measuring circulating levels of nonspecific proinflammatory markers. Neutrophil to lymphocyte ratio (NRL) is a new simple inflammatory marker which can be reliable in evaluating the inflammatory status occurring in morbidly obese patients. The aim of this study was to investigate the relationship between NLR as an index of chronic inflammation and anthropometric and metabolic parameters in a group of morbidly obese patients.

Patients and methods: Our study included 415 patients (130 men) with severe obesity (mean BMI=45.46±8.68 kg/m2, mean age=41.31±11.33 years), who were evaluated clinically (medical history, anthropometrics, and blood pressure measurements) and biologically (blood count, complete metabolic tests, and leptin level) in a research program for bariatric surgery.

Results: NLR was significantly higher in women (2.33±0.95 vs 2.09±0.87, P<0.05) and in non-smokers (2.35±1.01 vs 2.14±0.81, P<0.05). After adjusting for gender and smoking status, NLR positively correlated with BMI (r=0.132, P<0.01) waist circumference (r=0.225, P<0.001), and waist/height ratio (r=0.203, P<0.001), as well as with systolic blood pressure (r=0.136, P<0.05), serum C-reactive protein (r=0.170, P<0.001), HOMA-IR (r=0.121, P<0.05), and serum leptin level (r=0.172, P<0.01). In a linear regression analysis, with NLR as dependent variable and factors previously shown to significantly correlate to its level as independent variables, gender, BMI, and systolic blood pressure remained independently associated with NLR.

Conclusions: Gender, systolic blood pressure, and adiposity level are independent determinants of NLR in severely obese patients. Further studies are needed to elucidate the association of this parameter with obesity complications and prognosis.
