Background and aims. Bacterial vaginosis (BV) is one the more frequently identified genital syndrome among childbearing aged women. The basic condition that generates this condition is a modification in the vaginal microbiota. The aim of this paper is to briefly review the current status of the art of BV and to report the results of a pilot study performed with an innovative PCR based technique. Materials and Methods. 36 samples of vaginal fluid routinely submitted for the diagnosis of BV to the Unit of Microbiology – GRHL were comparatively evaluated by standard techniques and with the HP-Vaginiti e Vaginosi NLM kit that simultaneously detects in a quantitative way specific DNA from Candida (albicans, glabrata; krusei, tropicalis), Gardnerella vaginalis, Lactobacillus spp. and Atopobium vaginae. Results and conclusions. Candida spp. has been identified in 8 samples with culture and in 15 with the molecular test. 29 G. vaginalis were found by PCR whereas only in 7 samples a specific prescription for this microbe was present (of which 4 positive). A. vaginae has been identified in 20 samples by the molecular approach and Lactobacillus spp. was identified in 19 samples (by culture) and in 32 by PCR. The overall diagnosis of BV was made in 9 patients by standard techniques and in 7 by applying the molecular approach. (Cohen’s kappa test: 0,84). The findings of this study clearly demonstrate that the joint use of the routine culture- based techniques with the multiplex PCR methods amplifies by far the sensitivity of the overall diagnostic workflow of BV.

Patients with bacterial vaginosis are diagnosed with chronic generalized inflammatory and inflammatory-dystrophic periodontal diseases, such as chronic catarrhal gingivitis, periodontitis of initial and first severity. The aim of the study was to compare the effectiveness of the treatment of inflammatory and inflammatory-dystrophic periodontal diseases in women with bacterial vaginosis and their sexual partners. Materials and methods. 28 heterosexual couples aged 18-45 years took part in the survey. Clinical dental examination was performed at the time of treatment and 3 months after completion of treatment. Green-Vermilion indices, RMA (in Parma modification), complex periodontal index according to Leus (KPI), Svrakov's number were determined. Both groups of patients were examined for the presence of Gardnerella vaginalis and Atopobium vaginae in the oral cavity by PCR testing. The therapeutic course was the same for all groups of patients. General therapy included: "Fluconazole" 50 mg 1 time per day (7 days), "Clindamycin" 150 mg every 6 hours (5 days), starting from the 3rd day of antibiotics - probiotic "Symbiter acidophilus concentrated "(21 days), Calcium-D3-Nycomed 1 tab. during dinner 30 days. Local treatment included: oral baths of the drug "Stomatophyte" after morning and evening hygienic procedures (7 days), application of "Metrogil-dent" on the gums (7 days), the drug "Lizak" 1 tab. keep in the mouth until complete dissolution every 6 hours (5 days), after the use of "Stomatophyte" and "Metrogil - dent" - application of "Symbiter omega" on the gums in silicone caps at night (21 days). Results. In women, chronic generalized catarrhal gingivitis was detected in 10.71%, chronic generalized periodontitis of the initial degree in 64.29% and chronic generalized periodontitis of the I degree in 25%. In men who are carriers of pathogens of BV, chronic generalized catarrhal gingivitis was found in 7.14%, chronic generalized periodontitis of the initial degree in 60.71% and chronic generalized periodontitis in grade 32.1. General and local dental treatment of women with bacterial vaginosis and their sexual partners showed a positive objective dynamics of dental status. Thus, after 3 months of clinical and laboratory observations, there were no complaints, the state of oral hygiene improved significantly. If before the treatment the Green-Vermilion index in general in women with BV was 1.323 ± 0.035 points, then after 3 months it was equal to 1.032 ± 0.021. A similar dynamics was determined in men: from the starting index of 1.336 ± 0.041, the Green-Vermilion index decreased to 1.048 ± 0.036. 3 months after treatment, the PMA of patients decreased by 49.03%, in men - by 51.95%, no significant difference between the indicators of groups I and II was registered, while the difference between the results in the middle of groups I and II is significant . According to the KPI index, women had a significant difference between baseline and post-treatment outcomes of 1.98 points, while men had a score of 2.01 points. No significant difference was found between the results of groups I and II both before and after treatment. A similar positive dynamics characterizes the indicator - Srakov's number, according to this indicator before treatment and after differences between groups was not detected. The significant difference between the indicators in the group of women and men was 2,789 and 2,831, respectively. Before treatment and after the detection rate in the oral cavity, Gardnerella vaginalis and Atopobium vaginae did not have a significant difference between the group of men and women, but there was a clear difference between the parameters obtained at the initial examination and 3 months after treatment in the middle and second groups. Thus, Gardnerella vaginalis was detected less by 67.87% and 61.59%, Atopobium vaginae - by 65.79% and 58.65% in women and men, respectively. Conclusions. The developed and patented treatment regimen for patients with bacterial vaginosis contributes to the regression of inflammatory phenomena, improves oral hygiene, and is suitable for the treatment of women with this comorbidity and for the treatment of their sexual partners. The dynamics of reducing the percentage of detection of bacterial vaginosis pathogens corresponded to the dynamics of the clinical picture of periodontal disease in both women with bacterial vaginosis and men who were their sexual partners, which once again confirms the equal effectiveness of treatment for both gender groups.

Bacterial vaginosis is the most prevalent cause of abnormal vaginal discharge in women of childbearing age. It can have a major impact on quality of life and psychological wellbeing if frequently recurrent and strongly symptomatic. The use of molecular techniques to study the vaginal microbiome is increasing our understanding of the dynamic changes in flora that occur in health and disease. It might soon be possible to separate Gardnerella into different pathogenic and non-pathogenic species. Many groups are studying compounds that can disrupt the biofilm which is dominated by Gardnerella and Atopobium vaginae. Several studies in the last decade support the concept of bacterial vaginosis as a sexually transmitted infection.

Numerous studies have proved that periodontal pathology is an issue that requires a comprehensive and multidisciplinary approach in diagnosis, treatment and prevention, as most periodontal diseases are syndromic manifestations of somatic and psycho-somatic diseases, but there are little data on the periodontal status in patients with disturbance of the genital microflora. The aim of the study was to provide the grounds for the tactics of dental examination of child-bearing women with bacterial vaginosis and their sexual partners and to compare the results of different sex groups. Materials and methods. 28 heterosexual couples aged 18-45 years were examined. Objective periodontal examination included the calculation of Green-Vermilion oral hygiene index, papillary-marginal-alveolar index, complex periodontal index by P.A. Leus, Svrakov's iodine number. Amino test of oral fluid, assessment of oral fluid pH, identification of bacterial vaginosis pathogens, and in particular, Gardnerella vaginalis and Atopobium vaginae, in the oral cavity of the patients by polymerase chain reaction-diagnostics and bacterioscopically. Results. Chronic generalized catarrhal gingivitis was detected in 10.71% of the women, chronic generalized periodontitis in the initial stage was found out in 64.29% of the women, and chronic generalized periodontitis of the first degree in 25% of the female patients. Men, who were carriers of bacterial vaginosis, chronic generalized catarrhal gingivitis, made up 7.14%; chronic generalized periodontitis in the initial stage was found in 60.71% of the men and chronic generalized periodontitis was found in 32.14%. The values ​​of periodontal indices did not really differ between the indicators of different sex groups. Amino tests of the oral fluid in the women and men showed a positive result those points out the presence of volatile amines. The oral fluid pH is reduced in patients of both groups that indicate an inflammatory process in the oral cavity. All the patients have "key cells", which are exfoliated epitheliocytes with Atopobium vaginae and Gardnerella vaginalis adhered to them. This is one of the main markers of bacterial vaginosis. Conclusions. Summing up the results of the performed clinical and laboratory observations, it should be noted that when collecting the history of bearing aged women, the dentist should pay attention to the presence of diseases of the genital tract, and in particular, bacterial vaginosis. To detect inflammatory and inflammatory-dystrophic periodontal diseases in women of childbearing age, amino tests of oral fluid not only in women but also in their sexual partners for rapid diagnosis of pathogens such as bacterial vaginosis and vaginal vaginal vagina can be very informative.
