Comparative study of eosinophil count in peripheral blood, sputum and BAL fluid in patients of bronchial asthma

Bronchial Asthma is defined by the history of respiratory symptoms such as wheeze, shortness breath, chest tightness and cough that vary over time in intensity, together with variable expiratory airflow limitation. Airflow limitation may later become persistent course disease. To compare findings eosinophil counts peripheral blood, induced sputum bronchoalveolar lavage fluid asthmatic patients healthy individuals. This Case Control Cross sectional study was conducted among attending OPD at Sir Sunder Lal Hospital, BHU, Varanasi, diagnosis bronchial asthma (100) controls. Significant association found between eosinophilic absolute count (W = 1168.000, p 0.020), total serum IgE 1338.000, <0.001), BAL (χ2 94.589, 14.057, <0.001).
