Оценка эффективности применения активированной глицирризиновой кислоты у пациенток с ВПЧ-ассоциированными поражениями шейки матки с учетом уровня половых стероидных и гонадотропных пептидных гормонов

Abstract

Background: the persistence of human papillomavirus (HPV) infection with oncogenic protein expression causes changes in the stratified squamous epithelium, which is the immediate cause of cervical cancer manifestation. The use of the activated glycyrrhizic acid (GA) for HPV-associated cervical lesions is pathogenetically justified. During an experimental study on a culture of human cervical adenocarcinoma cells (HeLa line), it was shown that the antiproliferative effect of GA is enhanced by low concentrations of estradiol and weakened by testosterone. Aim: to evaluate the efficacy of the activated GA in female patients with HPV-associated cervical pathology with respect to the level of sex steroid and gonadotropin-releasing hormones Patients and Methods: a prospective study was conducted with the inclusion of 51 female patients with HPV-associated cervical pathology (ASCUS — atypical squamous epithelial cells of undetermined significance, LSIL — low-grade squamous intraepithelial lesion, HSIL— high-grade squamous intraepithelial lesion according to the Bethesda classification) and the absence of clinical and/or laboratory signs of hyperandrogenism. The following studies were performed: clinical examination, colposcopy, microscopic examination, cytology and immunocytochemistry, as well as hormonal status was evaluated. All female patients received Epigen Intim spray 0.1%, 3 times a day, for 30 days from the moment of inclusion in the study. If indicated, cervical conization was also performed. The treatment efficacy was evaluated 90±7 days after the therapy initiation based on the liquid-based HPV-PAP test results with the determination of p16/Ki67 oncogenic protein co-expression in the cervical epithelium. Changes in the colposcopy results were also evaluated. Results: it was found that the level of estradiol in patients with HSIL was lower versus the patients with ASCUS and LSIL (32 [32.0; 36.0] pg/ml versus 40 [34.5; 45.5] and 40 [33.0; 44.0] pg/ml, respectively, but the difference did not reach statistical significance (p=0.453). 90 days after the follow-up start, according to the cytology results of the cervical epithelium, 50 (98.0%) patients showed the absence of cervical intraepithelial lesions and the absence of p16/Ki67 oncogenic protein co-expression, 48 (94.1%) patients showed no high-risk (HR) HPV DNA, whereas HPV-associated colposcopy signs (anogenital warts, chronic cervicitis signs) persisted only in 6 (11.8%) patients. Conclusion: the use of activated GA in female patients of reproductive age with HPV-associated cervical lesions without clinical and/or laboratory signs of hyperandrogenism allowed to achieve high efficiency indicators: 98.5% — according to the cytology results, 83.3% — in reducing the HR-HPV viral load, 85.7% — in terms of p16/Ki67 oncogenic protein co-expression.
