spirometry has been used as a common diagnostic test in asthma. most of the patients with a mild asthma have a fev1 within normal range. hence, other diagnostic methods are usually used. the aim of this study was to evaluate whether eosinophil cationic protein (ecp) could be an accurate diagnostic marker of mild asthma. in this study diagnosis of asthma was made according to internationally acc...

objective(s) considering fair response to inhaled corticosteroids and reports of severe air way hyper responsiveness in chemical warfare victims (cwv), a role for eosinophilic inflammation (i.e. asthma) was postulated. the objective of this study was to determine the presence of eosinophilic inflammation in cwv by evaluation of sputum cellularity and eosinophil cationic protein (ecp). materials...

Eosinophilic inflammation in peripheral tissues is typically marked by the deposition of a prominent eosinophil protein, Galectin-10, better known as Charcot-Leyden crystal protein (CLC). Unlike the eosinophil’s four distinct toxic cationic proteins and enzymes [major basic protein (MBP), eosinophil-derived neurotoxin (EDN), eosinophil cationic protein (ECP), and eosinophil peroxidase (EPO)], t...

BACKGROUND Salivary eosinophil cationic protein (ECP) level has the potential to be an assessment tool for asthma. Its measurement is not well-established and needs standardization. We studied how passive drool (PD) and two commercial devices, Salivette(®) (cotton-based device) and Sorbette(®) (cellulose-cotton-based-device), may affect ECP levels during collection among healthy subjects. MET...

We read with interest the article by Qiu et al (Thorax 2007;62:475–82). In this paper, neutrophils and eosinophils were identified using mouse anti-human neutrophil elastase and anti-eosinophil cationic protein (ECP), both monoclonal antibodies (mAbs). mAbs against ECP have been used to detect total eosinophils, but immunostaining techniques evidenced that the number of ECP cells was higher tha...
