Frequency of Blood Eosinophilia in newly diagnosed Chronic Obstructive Pulmonary Disease patients.

Objective: To determine Blood Eosinophilia frequency in newly diagnosed Chronic Obstructive Pulmonary Disease patients.

Methods: An observational cross-sectional research on newly diagnosed COPD patients with age ≥ 40 years was performed at Ojha Institute of Chest Diseases, Dow University of Health Sciences Karachi. COPD patients diagnosed in outpatient clinic or admitted in Chest Unit during six-month period from September 2018 to May 2019 were selected.

Results: One hundred and fifty COPD patients were diagnosed and evaluated for , out of which 86 (57.3%) and 64 (42.7%) patients were and respectively with mean age of 63.72 ± 10.24 years. were 48 (32.0%), 15 (10.0%), and was present in 76 (50.7%) of patients. Spirometric severity of COPD was in 11 (7.3%), in 68 (45.3%), in 59 (39.3%), and in 12 (8.0%) patients. was present in 59 (39.3%) patients of COPD among which majority 43 (72.9%) were having 24 (40.7%) and 19 (32.2%) COPD respectively.

Conclusion: Frequency of Blood Eosinophilia in newly diagnosed COPD patients was high, among which most of the COPD patients were moderate to severe.
