Comparison of the responsiveness of two different asthma-specific QOL measures (AQLQ and cAQOL) in Korean patients with persistent asthma

Persistent Asthma Patient

Study Type: Observational
Official Title: Comparison of the Responsiveness of Two Different Asthma-specific QOL Measures (AQLQ and cAQOL) in Korean Patients With Persistent Asthma

Further study details as provided by Ajou University School of Medicine:

Primary Outcome Measures:
  • Two asthma quality of life measurement tool [ Time Frame: 24 weeks treatment ]
    Two asthma quality of life measurement tool (cAQOL, AQLQ) and the correlation between ACT

Secondary Outcome Measures:
  • Correlation between cAQOL/AQLQ [ Time Frame: treatment screening, week1,week12,week24 ]
    -Correlation between cAQOL/AQLQ and other clinical parameters including FEV1, and asthma exacerbation.

  • Association of asthma control therapy and a questionnaire [ Time Frame: 24 weeks treatment ]
    -The proportion of subjects with achieving well controlled asthma within ACT & cAQOL-guided management strategy with ICS or ICS/LABA based on GINA 2006 guidelines during 24 weeks.

  • asthma patient genotypes [ Time Frame: Screening ]
    Sub-group of ADRB2 and NK2R genotypes

Biospecimen Retention:   Samples With DNA
Sub-group of ADRB2 and NK2R genotypes
