The effectiveness of using a molded sorbent: Modified polyvinylpyrrolidone for the combined treatment of chronic endometritis

Objective: To improve the management of patients with chronic endometritis (CE) by using a molded sorbent—modified by polyvinylpyrrolidone (FSMP). Methods: This prospective study included 70 patients with CE divided into two groups: group 1 (n = 23) received traditional antibiotic therapy (from days 3 to 10 of the menstrual cycle); group 2 (n = 47), received antibiotics and FSMP was inserted from days 5 to 10. Results: At the end of therapy, group 1 had massive growth of pathogenic microflora in 21.7%, moderate growth in 69.6%, and no growth in 8.7% of cases. In group 2, after combined therapy, massive growth was observed in 4.3%, moderate growth in 44.7%, and no growth in 51.0%. In group 2 after 5 days, serum levels of interleukin-1β (IL-1β) were 1.9 times, of IL-6 were 7.0 times, and of IL-8 and IL-1 receptor antagonist were 1.3 times lower than in group 1. In uterine cavity aspirates, IL-1β decreased around 4.8 times, IL-6 by 11.8 times, IL-8 by 3.2 times, tumor necrosis factor-α by 3.9 times, and IL-1 receptor antagonist by 2.1 times in comparison to group 1. Conclusion: Combined therapy of FSMP with antibiotics is more effective in treating CE, because it contributes to the almost complete elimination of pathogens and toxins from the uterine cavity, blocking the local pro-inflammatory cascade. © 2021 International Federation of Gynecology and Obstetrics
