Abstract

Background: The induced sputum is used in the diagnosis of chronic airways diseases. Up to now there has not been performed studies in Poland describing the distribution of cells in sputum. The aim of the study was to work out the range of normal values for cells in sputum, based on a group of healthy Polish people living in Silesia region.
Methods: One hundred healthy volunteers in age 17-79 without respiratory symptoms were examined. They had normal spirometry, no airways hyperresponsiveness to metacholine and no history of allergic diseases. The sputum was obtained from 85 people. Viability, total and differential cell counts was performed.
Results: The range of the normal values for induced sputum cells was following [mean (± SD)]: macrophages 49.3% (11.5-77.1%), neutrophils 48.5% (9.6-87.2%), eosinophils 0.8% (<4.8), lymphocytes 1.4% (<4.2%). Smoking and age of subjects influenced the number and percent age of cells in sputum.
Conclusions:Finding of high percent age of eosinophils(>4.8%) in sputum may be helpful in the diagnosis of asthma. Counting of neutrophils and other cells is of limited practical value.
