Abstract

Objective: To determine frequency of blood eosinophilia in patients with COPD exacerbation Study   Design: Cross-sectional Study

Place and Duration of Study: This study was conducted at the Department of Pulmonology, Services Hospital Lahore from 01-02-2017 to 31-07-2017.

Informed consent was taken. The data was collected through a predesigned proforma. Bias effect was controlled by having eosinophil count measured from single laboratory of Services hospital by digital method followed by manual verification for those having >2% eosinophilia. All the information was written in pre-designed proforma.

Results: Out of 150 cases 90 % (n=135) were males and only 10% (n=15) were females. Mean age of presentation was 60.27+9.7.42% (n=63) patients were found to be having raised peripheral blood eosinophilia while 58% (n=87) patients had normal eosinophil count.Male to female ratio was 9:1
