Abstract
Neutrophil-lymphocyte ratio (NLR) is a test used to evaluate the systemic inflammation. There is little knowledge about the neutrophil-lymphocyte ratio in asthmatics. In our study, we aimed to evaluate NLR and to assess its relationship with clinical parameters in children with asthma. Four hundred and sixty-nine children diagnosed with asthma and followed in our hospital were included in the study. The control group included 170 children with no evidence of allergic disease (i.e. asthma, allergic rhinitis, eczema) or infection. Skin prick tests were performed using the same antigens for all patients. The immunoglobulin E levels and complete blood count were measured. There was no difference between the groups with regard to gender and age. Mean NLR was 2.07±1.41 in the study group and 1.77±1.71 in the control group. The difference was statistically significant (p=0.043). There was no statistically significant difference between NLR and gender, familial atopy, exposure to smoke, sensitivity to allergens (p>0.05). While mean NLR was weakly positively correlated with number of hospitalisations (r: 0.216; p: 0.012), the percentage of eosinophils was weakly negatively correlated with NLR (r: -0.195; p: 0.001). Mean NLR is higher in...Continue Reading
