Purpose: Non- cyctic fibrosis bronchiectasis (non-CFBE) is a chronic inflammatory lung disease which causes significant morbidity in children. Exacerbations in non-CFBE are associated with worsening lung function. Several laboratory parameters such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV) have been suggested to be as an indicator in various chronic inflammatory diseases. We aimed to asses the value of the NLR, PLR and MPV as markers of acute exacerbation in pediatric patients with non-CFBE. Methods: The NLR, PLR, and MPV values of 55 non-CFBE patients (during exacerbation and stable state periods) and 79 healthy control subjects were analyzed. Results: The mean ages for the patient and control group were 13.62±3.5 and 12.72±2.68 years, respectively. 64% of patients and 54% of control subjects were male. The white blood cell count, absolute neutrophil count, and NLR values were significantly higher in the exacerbation group than in the healthy control group (p<0.05). MPV and PLR values were not significantly different between the two groups. Only forced expiratory volume in one second (FEV1) and C-reactive protein level were significantly different (p<0.001) between the acute exacerbation and stable state periods in the Purpose: Non- cyctic fibrosis bronchiectasis (non-CFBE) is a chronic inflammatory lung disease which causes significant morbidity in children.

Only forced expiratory volume in one second (FEV1) and C-reactive protein level were significantly different ( p <0.001) between the acute exacerbation and stable state periods in the patient group. Conclusion: Despite the NLR value being significantly higher in children with non-CFBE than in healthy control subjects, it did not differentiate between the steady-state and acute exacerbations periods of the disease. PLR and MPV values also cannot be used as markers of acute exacerbation in children with non-CFBE.
