AIM: The study aimed to assess the effectiveness of alloferon in human papillomavirus (HPV)-associated cervical neoplasia (grade I) based on the analysis of the cytokine profile in cervical mucus as well as markers of apoptosis in cervical epithelial cells. MATERIALS AND METHODS: The study enrolled 98 women, including 55 women of reproductive age with cervical intraepithelial neoplasia (CIN) associated with HPV infection and 43 conditionally healthy women without HPV infection. Factors of cytokine response and markers of apoptosis under normal and pathology conditions were assessed and compared. RESULTS: The imbalance of pro-inflammatory and anti-inflammatory cytokines, in favor of the latter, is an important factor that supports the persistence of HPV-associated grade I CIN. Reducing caspase-3 and caspase-9, increasing interleukin-18, and subsequent activation of interferon gamma against the background of alloferon use are favorable signs of substantial elimination of the HPV. CONCLUSIONS: The results of this study show considerable elimination of HPV in patients with grade I CIN when using immunological antivirus therapy.
