Abstract

Background: Severe asthma is characterized by elevated levels of pro-inflammatory cytokines and neutrophilic inflammation in the airways. Blood cytokines, markers of 'systemic' inflammation, may be a feature of amplified inflammation in severe asthma. Objective: To detect differences in IL-8, TNF-α, IL-16 and IL-13 levels in the serum(s) of stable severe and mild-moderate asthmatics related to blood leucocytes proportion, airway calibre and exhaled nitric oxide (NO) levels. Methods: We assessed cytokine serum levels by ELISA and blood leucocyte counts by an alkaline peroxidase method in 20 healthy controls, 22 mild-moderate [forced expiratory volume in 1 s (FEV 1)(%pred): 89±3] and 14 severe asthmatics [FEV 1(%pred): 49±2]. Results: IL-8 and TNF-α levels were higher in severe asthmatics than in mild-moderate asthmatics or in controls (P
