Influence of epidemiological factors on asthma phenotypes among asthma patients attending a tertiary care center – A cross-sectional study

Abstract

Background: Asthma is a heterogeneous disease presenting with various phenotypes usually characterized by chronic airway inflammation. Aims and Objectives: The aim of the study was to identify epidemiology of bronchial asthma phenotypes in patients attending to tertiary care center. Materials and Methods: This was a descriptive cross-sectional study involving 69 patients who are suspected to have asthma according to the Global Initiative for Asthma guidelines. The data of each patient were collected on a proforma specially designed for this study on demographic data, socioeconomic status, body mass index, exposure to environmental factors, and other history-related questions. Sputum cytology and absolute eosinophil count were also examined using coGuide and P0.005). Conclusion: The factors associated with the asthma phenotypes will help us further in anticipating the clinical course and better management of the specific phenotypes.
