Association of induced sputum eosinophil, absolute eosinophil count and serum immunoglobulin E level in assessment of the clinical severity in bronchial asthma

Abstract

The study was done with the aim to determine the relationship between the severity of asthma in patient and the level of serum immunoglobulin E, peripheral eosinophil count and nature of sputum.Current research was conducted at the Department of Respiratory Medicine, GAIMS, Bhuj, India over one year. All subjects of Bronchial asthma distinct by Genetic Information Nondiscrimination Act (GINA) guidelines of age 17-61 year were registered. Severity of asthma was assessed by clinical features and by Forced expiratory volume in the first second (FEV1 in spirometry. Following evaluating the sternness of bronchial asthma all subjects undergo sputum examination for sputum eosinophil counts, blood sampling for absolute eosinophil counts and serum IgE levels. Elevated sputum eosinophil count (>3) was significantly elevated in additional subjects with severe persistent asthma even though extra than half of them had normal sputum eosinophil. An important association amid peripheral eosinophil count, sputum eosinophil count, and serum IgE with severe persistent asthma. Mean sputum eosinophil% augments considerably according to severity, demonstrates though affirmative association which was statistically important.The use of inexpensive and easy method with evaluation of AEC, sputum eosinophil count and evaluation of serum IgE level showed a straight measurement of inflammation of airway and allergic etiology of illness.
