CONTEMPORARY APPROACH TO CORRECT VAGINAL DYSBIOSIS DURING PREGNANCY

 

TOPICALITY. The problem of intra-amnionic infection is one of the most topical in modern perinatology. Besides infectious factor, the main pathogenetic mechanisms of fetal functional disorders in case of intrauterine infection are dysfunction of the fetoplacental complex and immune disorders of the mother and fetus, as well as microbiocenotic changes of the genitalia, including bacterial vaginosis (BV). The latter is one of the most frequent infectious diseases of the lower portion of the reproductive system and it is diagnosed in 20-26% of the pregnant [1, 2]. Bacterial vaginosis as a separate disease does not constitute a direct menace to the health of a pregnant woman. Although, in case of BV in the lower portions of the reproductive system an extremely high concentration of opportunistic microorganisms is being accumulated and stored, resulting in the increase of such complications of pregnancy as miscarriage, placental dysfunction, intrauterine infection of the fetus, premature labour, premature rupture of the amniotic sac, chorioamnionitis, postnatal septic complications [3].

Today the objective of BV treatment is restoration of the normal vaginal microbiocenosis, the therapy should be etiotropic and pathogenetically based, and the medicines administered should be effective and targeted. During pregnancy and lactation medicines with topical action are preferable, as they do not have a systemic effect. While choosing the agent to treat vaginal infection during pregnancy, doctors should consider its ingredients, their dosage and safety concerning the fetus.

The most effective means to treat BV beginning from the I trimester of gestation are the agents active against anaerobes, 5-nitroimidazole (5-NIAZ) derivatives, recommended by the WHO International Protocols and the Orders and Clinical Protocols of the Ministry of Public Health of Ukraine [4]. It is Terzhynan (France) that is an original medicine of a topical action containing 200 mg of Ternidazole (5-NIAZ derivative), 100 mg of Neomycin, 100 000 UN of Nystatin, 3mg of Prednisolone. The combination of 5-NIAZ with Neomycin, a 1st generation aminoglycoside, increases its antibacterial action. The combination of Ternidazole and Nystatin is rather advantageous, because first of all, candidiasis infection becomes 60% activated against the background of 5-NIAZ administration, and secondly, today bacterial-fungal associations prevail in the structure of infectious diseases. To achieve quick clinical anti-inflammatory effect the medicine is added by the glucocorticoid Prednisolone in the microdose of 3 mg, which is ten times less of the dose having a systemic action. Carnation and geranium oils intensify anti-inflammatory action of the ingredients and possess reparation properties.

Objective of our study was to estimate the efficacy of Terzhynan administration, a complex medicine of a topical action, in the treatment of bacterial vaginosis in pregnant women.

MATERIALS AND METHODS. 62 pregnant women in the II and III trimester of gestation with bacterial vaginosis were observed, they were treated with Terzhynan. The control group included 24 patients parity by their age and social position, treated with other antibacterial means for their bacterial vaginosis. The diagnosis of vaginal dysbiosis was made on the basis clinical data obtained (cream-like vaginal discharge), bacterioscopic and bacteriological examination, positive amine test.

RESULTS AND DISCUSSION. The analysis of Terzhynan administration to correct vaginal dysbiosis revealed the absence of allergic reactions and individual intolerance to it.

The research conducted found that clinical signs of bacterial vaginosis in the main group disappeared 4-6 days after the treatment, and in the control group – 7-10 days respectively. 2 weeks after the therapy with Terzhynan was completed, BV laboratory signs were absent in 98.0% of the pregnant, vaginal pH was normalized. Genital microbiocenosis in the 1st group in comparison with the 2nd one was characterized by reliable greater amount of lactobacilli (over 106 /mL) (1st group – 48.0%, the 2nd one – 62.0%), bifidobacteria (38.0% and 68.0% respectively), lactic acid streptococci (30.0% and 46.0%), with simultaneous decrease of Gardnerella strain (72.0% and 30.0%), Candida strain (62.0% and 46.0%) and other opportunistic microorganisms.

Dynamic observation of the groups found that during 3-6 months the recurrence frequency of vaginal dysbiosis after the treatment with Terzhynan in the 1st groups was 16.6% (7 cases) and in the control group – 40.9% (9 cases). None of the patients was complicated by mycotic colpitis after the treatment of vaginal dysbiosis, and due to this fact there was no need to use additional drugs.

Clinical evidence of the above mentioned peculiarities is the fact, that topical administration of Terzhynan allowed 2.2 times decrease of intrauterine infection, and 2 times – perinatal loss.

CONCLUSIONS. The research conducted demonstrated that bacterial vagonosis during pregnancy can be treated with antibacterial means not influencing the level of lactobacilli in the vagina.

Topical administration of Terzhynan during pregnancy results in quick reduction of acute signs of bacterial vaginosis, and effective prevention of possible relapse and complications of pregnancy.
