Abstract
Objective: to identify informative markers of the progression of cervical intraepithelial lesions of low degree.Materials and methods: the dynamics of the results of the cytological study of cervical epithelium, genotyping of human papilloma viruses of high carcinogenic risk (HPV) with an assessment of the viral load, an immunocytochemical study of the expression of protein p16 (p16INK4α), serum folic acid in 90 HPV-positive patients of reproductive age was analyzed. 43 of the 90 patients (47.8%) who made up group I had regression of the disease. Group II included 30 of 90 patients (33.3%) with disease persistence - no significant changes in the results of laboratory and instrumental research methods. Group III was 17 out of 90 patients (18.9%) with disease progression. Statistical processing of the results was carried out using parametric and non-parametric analysis methods using IBM SPSS Statistics 28.0.1.1 (developed by IBM Corporation), STATISTICA 13.5.0.17 (developed by StatSoft.Inc) and MedCalc 20.027. Results: factors that significantly distinguish patients with persistence or progression of low grade cervical intraepithelial lesions from women with regression of the disease are: earlier age of sexual onset, detection of atypical changes in low grade cervical epithelium, clinically significant HPV viral load, detection of p16INK4a protein expression, serum folic acid below 3.1 ng/ml. Conclusions: deficiency of serum folic acid in HPV of positive patients should be considered as a pathogenetically significant risk factor for the implementation of infection into the clinical form of the disease, which is confirmed by its correlation with the cytological detection of LSIL, progressive increase in the copy of HPV, and p16INKα expression. The patient management strategy, which provides a personalized assessment of the risk of progression of cervical intraepithelial lesions, expands the monitoring of patients with cervical neoplasias associated with HPV.
