A Study of Correlation between Asthma Control Test and Lung Function Parameters

Abstract

Introduction: Asthma control is the extent of observed asthma symptoms in patients and reduction in symptoms after treatment Simple screening tools are available to assess asthma control Asthma control test is a simple numerical scoring system that can be easily used on a routine basis Latest Global Initiative for Asthma (GINA) guidelines stress that asthma control is the main objective of asthma treatment In this COVID pandemic situation, there is an hesitancy in performing and undergoing pulmonary function tests among physicians and the patients Hence, in this study was planned to correlate the asthma control test values with FEV1 and other parameters like Peak Expiratory Flow Rate (PEFR), Absolute Eosinophil Count (AEC) and serum magnesium Aim: To study the correlation between asthma control test and FEV1;To study the correlation between asthma control test and other parameters like PEFR, AEC and Serum magnesium Materials and Methods: This study was conducted at Department of Pulmonary Medicine It is a cross-sectional observational study done from February 2019 to January 2020 Sample size was 55 Patients of Bronchial Asthma in line with GINA Guidelines were included in the study Results: Asthma control test had positive correlation with FEV1 with a spearman’s correlation of 0 2758 and p-value of 0 0414 which was statistically significant The spearman’s correlation between Asthma control test and AEC was -0 4583 with a p-value of <0 001, which was significant The correlation of asthma control test with serum magnesium was 0 3414 with a p-value of 0 010 Conclusion: Asthma control test score had a significant positive correlation with FEV1 and serum magnesium levels It also had significant negative correlation with AEC (inflammatory marker) Hence, Asthma control test can be used as tool for treatment response in the current COVID pandemic situation and also in resource limited settings [ABSTRACT FROM AUTHOR] Copyright of Journal of Clinical & Diagnostic Research is the property of JCDR Research & Publications Private Limited and its content may not be copied or emailed to multiple sites or posted to a listserv without the copyright holder s express written permission However, users may print, download, or email articles for individual use This abstract may be abridged No warranty is given about the accuracy of the copy Users should refer to the original published version of the material for the full abstract (Copyright applies to all Abstracts )
