    Abstract:
    Clinical-immunological examination of 41 patients with recurrent respiratory papillomatosis (RRP) included determination of phenotype CD3, CD4, CD8, CD16, CD25, CD56, HLA-DR in peripheral blood by flow cytofluorimetry, the levels of IFN-gamma, TNF-alpha, GM-CSF, IL-2, IL-4, IL-5, IL-10, IL-12, IL-13 in the laryngeal secretion by multiplex immunoassay. Interferon inhalation therapy was conducted to prevent recurrence in 23 patients after surgical treatment and in 18 patients as monotherapy. The efficacy of the monotherapy was 45.5%. Treatment with IFN-alpha raised the levels of cytokines modulating an immune response by Th1-type (IFN-gamma, IL-12, IL-2) and GM-CSF, and reduced the levels of IL-4, IL-10 and IL-13. Local treatment with recombinant IFN-alpha is effective in aggressive RRP. As prognostic markers of the treatment efficacy may serve baseline high levels of TNF-alpha and IL-4/IFN-gamma index in laryngeal secretion. Treatment efficacy can be assessed by raise of IFN-gamma, IL-2 and IL-12 in combination with reduction of IL-4/IFN-gamma index.
