Sex-based differences in factors associated with bronchial hyperresponsiveness in adolescents with childhood asthma
Young Hwan Kim, Yoon Young Jang, Jieun Jeong, Hai Lee Chung
Clin Exp Pediatr. 2021;64(5):229-238.   Published online January 14, 2021
Question: What factors are associated with bronchial hyperresponsiveness (BHR) in adolescents with childhood asthma?
Finding: Age, mold sensitization, and increased eosinophil count were associated with BHR in boys versus a reduced forced expiratory volume in 1 second/forced vital capacity ratio in girls. Early mold sensitization was a risk factor for persistent BHR in boys only.
Meaning: Sex-specific differences were observed in the factors associated with BHR in adolescents.
Utility of a forced expiratory flow of 25 to 75 percent as a predictor in children with asthma
Jung Wan Kang, Kyung Won Kim, Eun Soo Kim, Jun Young Park, Myung Hyun Sohn, Kyu-Earn Kim
Clin Exp Pediatr. 2008;51(3):323-328.   Published online March 15, 2008
Purpose : Asthma is defined as chronic inflammation of the lower small airways, and bronchial hyperreactivity (BHR) is a pathophysiologic feature of asthma. It has been proposed that although there is no direct variable capable of assessing the small airways, a forced expiratory flow of between 25 and 75 percent (FEF25-75) might be considered a more sensitive early marker of...
Analysis of the association between bronchial hyperresponsiveness and genetic polymorphism of β2-adrenoceptor in adolescents with long-term asthma remission
Hee Kang, Young Yull Koh
Clin Exp Pediatr. 2007;50(6):556-564.   Published online June 15, 2007
Purpose : We hypothesized that the persisting bronchial hyperresponsiveness (BHR) of adolescents with asthma remission may be controlled mainly by genetic factors, and the BHR of symptomatic asthma by airway inflammation. β2-adrenoceptor gene is considered to be a candidate gene in the development of BHR. Thus, β2-adrenoceptor gene polymorphism may be associated with the BHR of adolescents with asthma remission,...
Relationship between △FVC(% fall in FVC at the PC20 Dose of Methacholine) and Serum Eosinophil Cationic Protein(ECP) in 6-8 Year Old Children with Asthma
Dong In Suh, Jinho Yu, Young Yoo, Do Kyun Kim, Hee Kang, Young Yull Koh
Clin Exp Pediatr. 2005;48(10):1126-1131.   Published online October 15, 2005
Purpose : Bronchial hyperresponsiveness(BHR) is considered a hallmark of asthma. Increased levels of eosinophil cationic protein(ECP) have been identified in serum of asthma patients. Several studies have examined the relationship between serum ECP and bronchial responsiveness, expressed as methacholine PC20 in asthmatic patients, with conflicting results. The aims of this study were to examine the relationship between serum ECP and...
Bronchial Hyperresponsiveness and Atopy in 6-8 Year Old Children According to the History of Wheezing in Early Childhood
Jinho Yu, Young Yoo, Hee Kang, Young Yull Koh
Clin Exp Pediatr. 2004;47(8):873-878.   Published online August 15, 2004
Purpose : It is becoming generally recognized that wheezing in early childhood is a heterogeneous condition and does not always develop into asthma. This study aimed to determine characteristics of wheezing phenotypes in early childhood and investigate their relation to asthma. Methods : Two hundreds and sixty 6-8 year old children with past or present wheezeing were enrolled, and their history...
Assessment of Bronchial Hyperresponsiveness Using Chest Auscultation and Oxygen Saturation Measurement in Pre-school Children with a History of Wheezing
Young Yoo, Jinho Yu, Hee Kang, Eun Kyeong Kang, Young Yull Koh
Clin Exp Pediatr. 2004;47(4):417-423.   Published online April 15, 2004
Purpose : This study aimed to determine the efficacy and usefulness of chest auscultation and oxygen saturation measurement in the assessment of bronchial hyperresponsiveness to inhaled methacholine in pre-school wheezing children. Methods : One hundred and four children with histories of wheezing underwent bronchial challenges with nebulized methacholine using chest auscultation and oxygen saturation measurement. The challenge was considered positive when...
Peripheral Blood Eosinophil Counts and Serum ECP in Adolescents with Long-term Asthma Remission and Persistent Bronchial Hyperresponsiveness : Comparison with Adolescents with Symptomatic Asthma
Hee Kang, Young Yoo, Jinho Yu, Yang Park, Young Yull Koh
Clin Exp Pediatr. 2003;46(10):1013-1018.   Published online October 15, 2003
Purpose : Bronchial hyperresponsiveness(BHR) in asthma is thought to be a consequence of underlying airway inflammation. But the mechanism responsible for persistent BHR in adolescents with long-term asthma remission is poorly understood. The aim of this study was to examine whether BHR in adolescents with asthma remission is associated with peripheral blood eosinophilia and/or increased serum levels of eosinophil cationic...
Exhaled Nitric Oxide Concentration in Children with Asthma and Allergic Rhinitis : Association with Atopy and Bronchial Hyperresponsiveness
Kyu Min Nah, Yang Park, Eun Kyeong Kang, Hee Kang, Young Yull Koh, Sun Wha Lee, Domyung Paek
Clin Exp Pediatr. 2003;46(3):284-290.   Published online March 15, 2003
Purpose : A new airway inflammatory marker, exhaled nitric oxide(ENO) has been reported to correlate with bronchial hyperresponsiveness(BHR) and atopy. The purpose of this study was to analyze the relationship of ENO with BHR or atopy in patients with asthma and with allergic rhinitis. Methods : The subjects consisted of 55 children with asthma, 17 with allergic rhinitis, and 14 healthy...
Blood Eosinophil and Serum Eosinophil Cationic Protein as a Marker of Bronchial Hyperresponsiveness in Children with Suspected Asthma
Yang Park, Hee Kang, Eun Kyeong Kang, Young Yull Koh
Clin Exp Pediatr. 2002;45(12):1577-1584.   Published online December 15, 2002
Purpose : Airway inflammation is considered to be a characteristic feature of asthma, and eosinophils are recognized as the most important inflammatory cells. This study aims to assess the importance of blood eosinophil count and serum eosinophil cationic protein(ECP) levels as a non- invasive marker of bronchial hyperresponsiveness(BHR) in children with suspected asthma. Methods : This study used data from 87...
Relationship between Bronchial Hyperresponsiveness by Methacholine Provocation and the Severity of Asthma Symptoms, Pulmonary Function and Atopy
Sang Hyug Ma, Jung Mi Lee, Byung Hag Lim, Im Ju Kang
Clin Exp Pediatr. 1995;38(2):223-231.   Published online February 15, 1995
Purpose : Bronchial asthma is a disorder that is characteized by symptoms of reversible airway obstruction and increased responsiveness of the bronchus and to quantify the degree of br onchial hyperresponsivenes can be very helpful in determing the severity of disease and the prognosis. But the Methacholine provocation test is not always easy to be performed in all patients. Thus...
Eosinophil Cationic Protein in Relation to Bronchial Hyperresponsiveness in Asthmatic Children
Jin Tack Kim, Joon Sung Lee
Clin Exp Pediatr. 1993;36(12):1707-1715.   Published online December 15, 1993
The eosinophil is the major cell responsible for the inflammatory reaction in bronchial asthma. Secretion of granular components is probably of considerable importance for the inflammatory effects of the eosinophils, Eosinophil cationic protein (ECP) is the one of the secretory components of the eosinophil granule and is considered as an activation marker of eosinophil, Blood eosinophil count, serum concentration of...
