Immunological substantiation of complex therapy in patients with mild HPV-associated cervical intraepithelial neoplasia

Introduction. As is known, the development of invasive cervical cancer is preceded by cervical intraepithelial neoplasia of varying severity, which is a pathological process in which cells with varying degrees of atypia and impaired differentiation appear in the thickness of the stratified squamous epithelium of the cervix.

Objective. To study the  effect of  complex therapy in  patients with mild HPV-associated cervical intraepithelial neoplasia on the dynamics of local cytokine status and autoimmunity parameters.

Materials and methods. The study included 86 patients aged 35 to 40 years with morphologically verified mild cervical intraepithelial neoplasia. The main group consisted of 52 patients who, along with radio wave destruction of the cervix, were prescribed an immunostimulating drug with antiviral activity “Groprinosin-Richter” 1000 mg 3 times a day for 10 days 10–14 days before destruction and similar 2 courses after 10–14 days after it. The comparison group included 34 patients who underwent only radio wave destruction of the cervix.

Results. An analysis of the outcomes of low-grade squamous intraepithelial lesions after 6 months showed that in the main group, CIN I regression was observed in 92.3% of patients, persistence – in 7.7% of cases, while in the comparison group, CIN I regression was noted in 73,5% of cases, persistence – in 26.5% of patients.

Conclusions. Conducting complex therapy, including radio wave destruction and the use of a drug with immunostimulating and antiviral activity “Groprinosin-Richter” in  patients with low-grade HPV-associated cervical intraepithelial neoplasia, leads to the elimination of the initial imbalance of cytokines and normalization of autoantibody levels, helping to reduce the likelihood of HPV persistence and CIN progression to invasive cervical cancer uterus.
