Dissociation between the state of leukocyte adhesiveness/aggregation in the peripheral blood and the availability of the CD11B/CD18 and CD62L antigens on the surface of the cells in patients with stress.
We adopted whole blood flow cytometry and direct labeling of the CD11b/CD18 and the CD62L antigens to study the relationship between their expression on the surface of peripheral leukocytes and the state of leukocyte adhesiveness/aggregation (LAA) as revealed by the leukergy test. We examined patients with infection/inflammation, acute stress and controls. The mean +/- S.D. channel fluorescence intensity of CD11b/CD18 antigen did not differ between patients with infection/inflammation (173 +/- 78) and controls (167 +/- 72). However, a significant (p < 0.0001) difference between these groups was noted regarding LAA state. There was a significant (p = 0.04) reduction in CD11b/CD18 in stress (135 +/- 60) and a significant (p < 0.001) increment in LAA. In both study groups, there was a significant reduction in CD62L. Patients were divided into those with CD11b/CD18 above and below the control's average. No correlation was found between the antigens and LAA. We assume that LAA in patients with stress state is CD11b/CD18 and CD62L independent.
