Local cytokine therapy in a comprehensive treatment of HPV-associated cervical diseases

Abstract

Aim. To analyze an efficacy of monotherapy and combined therapy (an immunomodulator + radio wave ablation) in patients with low-grade squamous intraepithelial lesion (L-SIL) caused by HPV infection. Materials and methods. The study included 210 women with human papillomavirus infection which was identified using real-time polymerase chain reaction (PCR). All women underwent a comprehensive examination which included history taking, general and gynecological examinations, extended colposcopy and a bacterioscopy of Gram-stained vaginal smears. A quantitative determination of vaginal microflora composition by PCR was carried out. Conclusion on either inflammatory response is present or absent was made on the basis of an inflammation index magnitude: with a value of more than 60% indicating a presence of local inflammation signs. Based on cervical cytology data a group consisting of 79 women who had L-SIL was formed. Patients were divided into 2 subgroups: the main one (n=45) who received combined treatment with radio wave ablation + an immunomodulator and a control one (n=34) who received only local monodestruction of L-SIL foci followed etiotropic treatment. Results and discussion. An efficacy of combined treatment which included radio wave ablation + an immunomodulator was higher compared to monodestruction only - 86.7% vs 64,7% respectively. It is important that by 6th month of follow-up a relapse of human papillomavirus infection occurred in 4.5 and 23.5% of patients of main and control groups respectively. Local inflammation was assessed as positive with an inflammation index of more than 60%. So after 6 months of follow-up this indicator decreased by 83.3 and 54.2% in the 1st and 2nd groups respectively. Clinical manifestations of an inflammatory process in the cervix was observed only with CIN recurrence. In addition, combined therapy provides a higher rate of human papillomavirus elimination at 6 months and faster cervix epithelization followed treatment by ablation.
