An assessment of concentrations of soluble CD4 and CD8 receptors in serum before and after surgical treatment in patients with chronic maxillary sinusitis

Background: The aim of this study was to assess the concentrations of soluble CD4 (sCD4) and sCD8 receptors in serum of patients before and after surgical treatment of chronic maxillary sinusitis. Methods: We examined 57 patients, aged 20-63 years (mean age, 41 +/- 0.5 years), and divided them into four groups: group 1, 14 patients with chronic maxillary sinusitis without allergy; group 11, 15 patients with chronic maxillary sinusitis with allergy; group 111, 16 patients with cyst of maxillary sinuses without allergy (control); and group IV, 12 patients with cyst of maxillary sinuses with allergy (control). The assay of sCD4 and sCD8 receptor concentrations was performed by means of enzyme-linked immunosorbent assay method. The concentrations of sCD4 and sCD8 receptors before and after 30 days of surgical treatment of maxillary sinuses were examined. Results: In our studies the increase of concentration of sCD4 in groups I and H in comparison with the concentration in control groups were statistically significant. The differences between mean concentrations of sCD8 in groups I and II and in the control groups were not statistically significant. After surgical treatment of chronic maxillary sinusitis, a significant decrease in values of sCD4 and sCD8 in comparison with the results before surgical treatment suggest that the measurement of cell suppression product concentration can be used to assess the extirpation of the inflammatory process and the effectiveness of the operation method. Conclusion: Changes in concentration of sCD4 and sCD8 manifest activation or suppression of cells with particular receptor expression.
