INTRODUCTION: Allergic rhinitis and bronchial asthma are thought to be sequela of the same allergic airway disease. The relationship between both diseases has been confirmed by various clinicopathological epidemiological and immunological studies. In this study, we tried to establish a different relationship between both diseases and strengthen the concept of “One-airway one disease.” MATERIALS AND METHODS: A total of 100 patients visiting ear, nose, and throat and respiratory medicine outpatient department were taken. They were divided into two groups of fifty each and were studied for various mediators of inflammation. Group 1 consisted of patients of allergic rhinitis and Group 2 consisted of patients of bronchial asthma. RESULTS: Most of the patients in Group 1 were in the age group of 21–30 years (40%) and in Group 2, in the age group of 11–20 years (38%) with a mean age 28.4 ± 1.3 years. The most common symptoms in Group 1 patients were sneezing (90%) and rhinorrhea (68%) and in Group 2 wheezing (86%), followed by shortness of breath (66%). The most common sign in Group 1 was B/L inferior turbinate hypertrophy (70%), while in Group 2, it was rhonchi (76%). Mean absolute eosinophil count was 575.35 in Group 1 and was 446.61 in Group 2. Nasal smear for eosinophil was positive for 86% of patients in Group 1 and bronchial lavage showed eosinophilia in 64% of Group 2 patients. Mean total serum immunoglobulin E was 777.23 IU/ml in Group 1 and 662.08 IU/ml in Group 2. The incidence of bronchial asthma in patients of allergic rhinitis was 36%, while the incidence of allergic rhinitis in patients in bronchial asthma was 74%. CONCLUSION: Thus, in our study, we found that both the diseases were closely linked clinicopathologically epidemiologically as well as immunologically pointing toward the concept one-airway one disease.
