Background: Asthma is a very common disease throughout the world. Among various types of asthma eosinophilia is one of the important factor to be considered in deciding management protocols. Different types of asthmatic patients can have varying level of eosinophilia. We wanted to see if age can have any effect on the prevalence and level of eosinophlia in asthmatic patients. Objective: Objective of the present study was to determine the frequency of eosinophilia in bronchial asthma patients of different age groups. Methodology: This cross-sectional study was performed at Pulmonology Department of Ayub Teaching Hospital Abbottabad Pakistan from February 2019 to July 2019 on 116 patients. All new cases presented with bronchial asthma of age 20- 70 years were enrolled. Detailed history and clinical examination followed by spirometry was done. Each patient`s blood eosinophils count was performed at hospital laboratory and values were recorded. Data was analyzed with SPSS version 24. Results: Mean age of the patients was 41 years +-11.02. Patients of age 20-40 years were 56 (48%) and of age 41-70 years were 60 (52%). Males were 79 (68%) and females were 37 (32%). Mean weight was 65Kgs+-12.73. Family history of asthma was positive in 77 (66%) patients and was negative in 39 (34%) patients. Seventy one (61%) patients had eosinophilia while 45 (39%) patients didn`t have eosinophilia. We found no significant differences regarding eosinophilia among different age and gender groups. Conclusion: Eosinophilia is prevalent in a majority of bronchial asthma patients. There is no significant difference in eosinophilia among different adult age groups.
