Asthma is an inflammatory, reversible and progressive disease with episodes of exacerbations. Both the Nasal and Bronchial mucosa are the elements of united airway disease and Eosinophils measured from this mucosa can be an indirect marker of Airway inflammation (AI) in asthma and Allergic Rhinitis (AR). Eosinophil infiltration is hallmark feature of pathogenesis of airway inflammation and is raised in acute and chronic variants. Sputum Smear cytology for Esonophilis (SSE), marker of AI is used as research tool in specialized Institutions to measure AI. In this study I00 patients were enrolled. 52% had Bronchial Asthma (BA) whereas 48% of them had associated Allergic Rhinitis (BAAR). The severity of asthma was assessed as per FEV1classification. There was no statistically significant difference between sputum eosinophilis in both groups (P=0.298). There was no statistically significant association between SSE and severity of Asthma in both groups (P=0.298 and P=0.129)
