Pregnancy against the background of bacterial vaginosis: modern ways of solving the problem

Abstract

Pregnancy against the background of bacterial vaginosis is accompanied by a high risk of obstetric and perinatal complications. Therefore, bacterial vaginosis must be treated in pregnant women. Screening and therapy are performed at the beginning of the II or III trimester of pregnancy. The survival of colonies of pathogenic microorganisms in biofilms is significantly increased, so they can remain viable even at high concentrations of antiseptic. The main advantage of using local combined antiseptic agents is the ability to achieve the maximum concentration of the antibiotic exactly in the place of the greatest accumulation of pathogens with the ability to influence biofilms. The objective: was to compare the efficacy and safety of various regimens of therapy with topical combined drugs (Lynda and Meratin Combi) in pregnant women with bacterial vaginosis. Materials and methods. The biocenosis of the vagina was investigated in 351 pregnant women in the II trimester. The diagnosis of bacterial vaginosis was established if the patient had any three of the Amsel criteria. Results. Microbiological screening of the vaginal biocenosis in the II trimester of pregnancy showed that normocenosis among the surveyed was 18.5%; bacterial vaginosis – 31.6%; vulvovaginal candidiasis – 26.5%; aerobic vaginitis – 22.8%, trichomonas vaginitis – 0.6%. Against the background of bacterial vaginosis, the threat of miscarriage, placental dysfunction occurred 6 times more often, anemia and preeclampsia three times more often, gestational pyelonephritis twice more often than in healthy pregnant women. In most patients, the sensitivity of the vaginal microflora to metronidazole and ornidazole is the same, but depends on the dose of the antiseptic, the sensitivity to miconazole was almost twice as high as to nystatin. This confirms the need for a differentiated selection of antiseptics for local therapy of bacterial vaginosis during pregnancy. Conclusion. A more rapid dynamics of the disappearance of the main symptoms of bacterial vaginosis and the normalization of the pH of the vaginal secretion were noted after the use of the drug Limenda. In order to prevent relapse of the disease, it is necessary to carry out the second stage of treatment with probiotics to restore its own lactoflora.
