The clinical significance and application of cytological examination of induced sputum in chronic airway disease

Objective To explore the clinical value of cytological examination of induced sputum in chronic airway disease.Methods Sixty five cases(age:47±15 yr) with chronic cough were enrolled,including 20 males and 45 females.Eighty cases(age:48±14 yr) with asthma were enrolled,including 29 males and 51 females.Sixty eight cases(age:66±10 yr) with COPD were enrolled,including 46 males and 22 females.Results The percentage of those patients whose EOS above 3% was 20%(13/65) in patients with chronic cough.These patients were considered to be suffered from eosinophilic bronchitis.The means of EOS and NEU percentages in asthma patients were(4.62±3.51)% and(42.59±23.90)%.Among these cases,the percentage of those patients whose EOS above 1% was 83.7%(67/80) and NEU was over 61% was 25.0%(20/80) in patients with asthma.The EOS and NEU percentages mean in COPD patients were(0.80±0.8)% and(54.43±21.51)%.The percentage of those patients whose EOS above 1% was 29.4%(24/68 and NEU above 61% was 55.8%(38/68) in patients with asthma.For EOS and NEU percentages,there was markedly difference between asthma group and COPD group(P<0.01).Conclusion The cytological examination in induced sputum may be meaningful for differential diagnosis of chronic cough and treatment of asthma and COPD.
