Overweight and obesity play a negative role in gynecological and obstetric practicE.In women, the frequency of infectious pathology increases against the background of metabolic disorderS.The most common form of infectious vaginitis is bacterial urogenital candidiasis, in the etiological structure of which a significant role belongs to the fungi Candida albicans, as well as Candida non-albicans: C.glabrata, C.tropicalis, C.parapsilosis, C.krusei. Associations of Candida fungi with various representatives of opportunistic microflora, such as gram-positive and gram-negative aerobic, facultative-anaerobic and obligate-anaerobic microorganisms, are often formed. As a result, numerous bacterial pathogens multiply and the number of lactobacilli, which are usually part of the bacterial flora of the vagina, is significantly reduced. In bacterial vaginosis (BV), the concentration of anaerobic pathogens Peptostreptococcus sp, Gardnerella vaginalis, Peptostreptococcus Mobiluncus sp, Mycoplasma hominis can increase 100 timeS.Activation of Atopobium vaginae and Gardnerella vaginalis, which play a “key” role in the pathogenesis of BV, has been proven. The aim of the study was to study changes in the vaginal microbiome in women with candidiasis and bacterial vaginosis in order to improve existing treatment regimenS.We examined 120 women of reproductive age with overweight and obesity. The degree of microbial contamination was determined and the maximum possible spectrum of aerobic and facultative-anaerobic microflora was detected. In women with vulvovaginal candidiasis, overweight and obesity, a high concentration (lg5.8 CFU/ml) of Candida fungi was found, and in 95% of patients two-, three- and four-component associations of Candida fungi with various representatives of conditional pathogenic microflora. Lactobacillus deficiency was found in 58.3% of patients, and their complete absence – in 10.0%. Bacteriological examination of the vaginal contents of women with vaginosis and obesity revealed significant dysbiotic disorders of the vaginal microflora, three-, four- and even five-component associations of anaerobic and facultative anaerobic microflora with a predominance of anaerobeS.A low seeding level of lactobacilli (lg2.2 CFU/ml) was established. Thus, the gram-positive anaerobic and facultative anaerobic microflora of Firmicutes have a significant share in the spectrum of vaginal microflora in overweight and obese patients, in contrast to non-obese women of reproductive agE.In women of reproductive age with vulvovaginal candidiasis and obesity, in contrast to non-obese patients, a higher frequency of fungal-bacterial associations, a higher quantitative level of vaginal contamination by Candida albicans and non-albicans with a lack or general absence of lactoflora.

The vaginal microbiome is an intricate and dynamic microecosystem that constantly undergoes fluctuations during the female menstrual cycle and the woman’s entire life. A healthy vaginal microbiome is dominated by Lactobacillus which produce various antimicrobial compounds. Bacterial vaginosis (BV) is characterized by the loss or sharp decline in the total number of Lactobacillus and a corresponding marked increase in the concentration of anaerobic microbes. BV is a highly prevalent disorder of the vaginal microbiota among women of reproductive age globally. BV is confirmed to be associated with adverse gynecologic and obstetric outcomes, such as sexually transmitted infections, pelvic inflammatory disease, and preterm birth. Gardnerella vaginalis is the most common microorganism identified from BV. It is the predominant microbe in polymicrobial biofilms that could shelter G. vaginalis and other BV-associated microbes from adverse host environments. Many efforts have been made to increase our understanding of the vaginal microbiome in health and BV. Thus, improved novel and accurate diagnosis and therapeutic strategies for BV have been developed. This review covers the features of vaginal microbiome, BV, BV-associated diseases, and various strategies of diagnosis and treatment of BV, with an emphasis on recent research progresses.

Introduction. Bacterial vaginosis (BV) is the most common vaginal disorder in reproductive-age women. The condition is characterised by the replacement of a healthy, lactobacilli-dominated vaginal microbiota by anaerobic and facultative anaerobic bacteria. BV increases the risk of acquisition of STIs and is associated with pregnancy complications. Although the composition of the bacteria in BV varies between individuals, there are some species such as Gardnerella, Atopobium, Mycoplasma, Snethia, Megasphera, Dialister, etc., that are found most frequently. Material and methods. Literature research to the importance of Atopobium vaginae in BV and treatment options. Results. Atopobium (A.) vaginae is an important component of the complex abnormal vaginal flora in BV; even though A. vaginae, like Gardnerella vaginalis, has also been detected in the normal flora, it is much more common in BV patients. A. vaginae has been shown to play an important role in the pathophysiology of BV and is thought to be at least a partial cause of the known negative sequelae. The presence of A. vaginae in the BV-associated biofilms and its resistance to some antimicrobial substances has been described – this seems to have a major impact on treatment outcome. Conclusion. Current scientific data demonstrate that dequalinium chloride (Fluomycin®) is one of the valid therapeutic options for BV treatment, since it displays a broad antimicrobial spectrum against relevant vaginal pathogens, especially against G. vaginalis and A. vaginae, without having safety concerns.

BACKGROUND: Bacterial vaginosis (BV) is one of the most common diseases affecting women of reproductive age. The main problem of BV is the low efficiency of traditional methods of treatment with a frequent recurrence of up to 50%. MATERIALS AND METHODS: A total of 59 patients were examined and treated with the diagnosis of BV, which was confirmed in accordance with the Amsel criteria. The main group included women with BV and their male partners, whereas the compared group included only women with BV. All women were treated with systemic metronidazole and topical clindamycin, and suppositories with lactic acid were prescribed at the second stage. The men partners were treated systemically with metronidazole and topically with clindamycin. RESULTS: Gardnerella vaginalis, Atopobium vaginae, and Prevotella were the most commonly identified bacteria in the vaginal discharge. In men, BV-associated bacteria were found in the foreskin of the glans penis and distal urethra. The similarity of the microflora of the genital organs of women and their male partners was determined. In women with sexual partners who were treated 6 months after the therapy, the number of BV-associated bacteria was detected two or more times less frequently than in patients in the comparison group. For the men, the number of complaints and clinical symptoms significantly decreased after the treatment. Significant decreases in Gardnerella vaginalis, Atopobium vaginae, Prevotella spp., Leptotrichia amnionii, and Mobiluncus were achieved in the foreskin and Gardnerella in the urethra. In the main group of women, the frequency of BV recurrences recorded was 2.3 times less than that in the comparison group. CONCLUSION: The treatment of partners of women with BV effectively reduces the growth of BV-associated bacteria and significantly decreases the frequency of recurrences.

Aim: To determine the frequency of Bacterial vaginosis by pap smear cytology and find its association with its sociodemographic determinants. Study design: Cross sectional analytical study Place and duration of study: Department of Histopathology, Shaikh Zayed Hospital, Lahore from 1st January 2016 to 31st October 2016. Methodology: Two hundred and sixty pap smears of married women of reproductive age group with vaginal discharge who attended Gynecology OPD were included. Proper history regarding age, socioeconomic status, age of marriage, literacy level, smoking, and nutritional status was taken. Results: Disease prevalence was found to be 19.2%(50)in this sample of 260 while 9.1% had Candidiasis, 47%, 17.2% ,3.7%, 4.1% had Mild nonspecific inflammation, Moderate nonspecific inflammation, Moderate to severe nonspecific inflammation, and negative smears respectively. Bacterial vaginosis was associated with age, monthly income, illiteracy, early age at marriage, history of abortion and nutritional status with significant p-value ≤ 0.05. However no association was found between the disease and marital status, smoking and pallor. Conclusion: Low socioeconomic status, literacy, age >35, nutritional status is strongly related to occurrence of bacterial vaginosis in women of reproductive age group with vaginal discharge. Key Words: Bacterial vaginosis, Pap smear, Sociodemographic determinants

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.

Qualitative and quantitative assessment of microbes making the microbiocenosis of genital tract in women with inflammatory and proliferative diseases of cervix using Femoflor-16 test was the aim of the research. Scrapings of cervix and vaginal fornix in 100 women of reproductive age with cervicitis, vaginitis and in 31 women with cervical pseudoerosion (ectropion) were studied. The control group consisted of 35 relatively healthy women preparing for pregnancy. Cervical and vaginal dysbiosis was found in women with inflammatory diseases of cervix in 37.0% of cases, in women with pseudoerosion in 32.2% of cases. These are 3.3 (р<0.005) and 2.8 (р<0.02) times as much as in the group of healthy women preparing for pregnancy (11.1%). Dysbiosis structure was represented primarily by obligate anaerobic agents such as Gardnerella vaginalis, Atopobium vaginae, Eubacterium spp. in association with other opportunistic bacteria that are clinically most significant microorganisms colonizing female genital tract. Mycoplasma and yeast-like fungi of Candida species were found primarily with anaerobes. Aerobic and mixed dysbiosis were only found in 7% of cases in women with inflammatory diseases. Femoflor-16 test is a readily available, fast, efficient, up-to-date method enabling one to begin with early adequate antibacterial therapy and monitor it.
