The place of adhesion molecules that have a role in the immigration of intravascular leukocytes to the tissue with inflammation in the pathogenesis of chronic obstructive pulmonary disease (COPD) is controversial. Our purpose in this study was to examine the levels of soluble intracellular adhesion molecule-1 (sICAM-1) and Mac-1 (CD11b/CD18), lymphocyte function associated antigen-1 (LFA-1) in both neutrophils and lymphocytes in stable patients with COPD and in the healthy control groups consisting of non-smokers, and in smokers without COPD and also to evaluate the relationship between the parameters related to the severity of the disease. Peripheral venous blood samples of all the individuals were collected, and levels of sICAM-1 was measured quantitatively with ELISA method. Flow cytometry was used for Mac-1 and LFA-1 levels. Twenty-four stable patients with COPD (group I), 13 smokers (group II) and 14 healthy non-smokers (group III) were included in this study. In the COPD group, 12 smokers patients were considered as group IA, and 12 patients with non-smokers and biomass exposure were considered as group IB. No statistically significant differences were seen in LFA-1 examined in peripheric blood (PB) neutrophils and lymphocytes and sICAM in groups I, II, and III. Mac-1 examined in PB neutrophils was found to be significantly lower in group I when compared to groups II and III, however no difference could be seen in smokers' group of II and the control group III. Mac-1 examined in PB lymphocytes were found to be higher in group I according to group II, however no statistically significant difference was seen between group I and control group. No statistically significant differences were seen in all adhesion molecules levels in group IA and group IB. As a result; it was found that Mac-1 levels in PB neutrophils were decreased with the developing of COPD and Mac-1 levels in PB lymphocytes were decreased in smokers, however increased following the development of COPD. No differences existed in sICAM and LFA-1 levels dependent on smoking and/or COPD.
