There were no differences in the differential cell counts of eosinophils (1.3 vs 3.8%), neutrophils (44 vs 32%), and lymphocytes (0.6 vs 0.6%). While the proportion of macrophages was lower (36 vs 54%; p < 0.05), the absolute number (41 vs 19 x 10(4) cells; p < 0.05) was higher in the selected portion. In summary, selection of all portions of induced sputum from the expectorate minimized the confounding influence of saliva. Loss of nonsquamous cells in the residual portion was variable but usually less than one third of those in the selected portion. With one exception, this loss had little influence on the differential counts of inflammatory cells. Similar observations apply to eosinophilic cationic protein levels. We conclude that, in healthy subjects and treated asthmatics, inflammatory markers in the selected portion of the expectorate can be used to represent those in the lower respiratory tract in general.
