Cell therapy in the complex treatment of chronic rhinosinusitis in children

Background: Determination of the general immune status and the effectiveness of the complex treatment with local immunostimulation (autologous mononuclear cells) of chronic rhinosinusitis in children.

Material and methods: The general immunity status and the effectiveness of the complex treatment with local immunostimulation were examined by the application in the maxillary sinuses of activated autologous mononuclear cells in 19 children with chronic rhinosinusitis and 116 healthy children.

Results: The presence of allergic reactions by increase in IgE and CD4/CD8 index was determined in patients examined. The sensitization to streptococcal antibodies was assessed by the cell sensitization data and the presence of streptococcal antibodies according to ASL-0 data. The inhibition of the T-cells was functional decrease of T-lymphocytes in the TTBL test with phytohemagglutinin and tendency towards a decrease of the T-CD-3 lymphocytes titer. The compensatory activation of the B-cells (increase in the IgA titer) was determined. The objective follow-up examination of the patients over one year revealed the absence of hyperemia and edema of the nasal mucosa, while an insignificant nasal obstruction was present in 5 children. The rhinomanometric examination demonstrated an increase in total volume indices and a decrease in the total nasal resistance in all treated children. The new method of local immunocorrection of chronic rhinosinusitis in children proved to be clinically effective.

Conclusions: There were determined increased IgE, CD4 / CD-8 index and CIC (PEG-8% with low molecular weight), cellular sensitization to streptococcal antibodies according to TTBL data, inhibition of the T-cells and tendency towards a decrease of T-CD-3 lymphocytes. Also, the compensatory activation of the B-cells (increase in the IgA titer) was determined.
