The role of sialidases in the pathogenesis of bacterial vaginosis and their use as a promising pharmacological target in bacterial vaginosis.

Bacterial vaginosis (BV) is an infection of the genital tract characterized by disturbance of the normally Lactobacilli-dominated vaginal flora due to the overgrowth of Gardnerella and other anaerobic bacteria. Gardnerella vaginalis, an anaerobic pathogen and the major pathogen of BV, produces sialidases that cleave terminal sialic acid residues off of human glycans. By desialylation, sialidases not only alter the function of sialic acid-containing glycoconjugates but also play a vital role in the attachment, colonization and spread of many other vaginal pathogens. With known pathogenic effects, excellent performance of sialidase-based diagnostic tests, and promising therapeutic potentials of sialidase inhibitors, sialidases could be used as a biomarker of BV. This review explores the sources of sialidases and their role in vaginal dysbiosis, in aims to better understand their participation in the pathogenesis of BV and their value in the diagnosis and treatment of BV.

Point-of-care testing and treatment of sexually transmitted and genital infections to improve birth outcomes in high-burden, low-resource settings (WANTAIM): a pragmatic cluster randomised crossover trial in Papua New Guinea.

BACKGROUND: Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and bacterial vaginosis have been associated with adverse maternal and perinatal outcomes, but there is conflicting evidence on the benefits of antenatal screening and treatment for these conditions. We aimed to determine the effect of antenatal point-of-care testing and immediate treatment of C trachomatis, N gonorrhoeae, T vaginalis, and bacterial vaginosis on preterm birth, low birthweight, and other adverse maternal and perinatal outcomes compared with current standard of care, which included symptom-based treatment without laboratory confirmation. METHODS: In this pragmatic cluster randomised crossover trial, we enrolled women (aged ≥16 years) attending an antenatal clinic at 26 weeks' gestation or earlier (confirmed by obstetric ultrasound), living within approximately 1 h drive of a study clinic, and able to provide reliable contact details at ten primary health facilities and their catchment communities (clusters) in Papua New Guinea. Clusters were randomly allocated 1:1 to receive either the intervention or control (standard care) in the first phase of the trial. Following an interval (washout period) of 2-3 months at the end of the first phase, each cluster crossed over to the other group. Randomisation was stratified by province. Individual participants were informed about trial group allocation only after completing informed consent procedures. The primary outcome was a composite of preterm birth (livebirth before 37 weeks' gestation), low birthweight (<2500 g), or both, analysed according to the intention-to-treat population. This study is registered with ISRCTN Registry, ISRCTN37134032, and is completed. FINDINGS: Between July 26, 2017, and Aug 30, 2021, 4526 women were enrolled (2210 [63·3%] of 3492 women in the intervention group and 2316 [62·8%] of 3687 in the control group). Primary outcome data were available for 4297 (94·9%) newborn babies of 4526 women. The proportion of preterm birth, low birthweight, or both, in the intervention group, expressed as the mean of crude proportions across clusters, was 18·8% (SD 4·7%) compared with 17·8% in the control group (risk ratio [RR] 1·06, 95% CI 0·78-1·42; p=0·67). There were 1052 serious adverse events reported (566 in the intervention group and 486 in the control group) among 929 trial participants, and no differences by trial group. INTERPRETATION: Point-of-care testing and treatment of C trachomatis, N gonorrhoeae, T vaginalis, and bacterial vaginosis did not reduce preterm birth or low birthweight compared with standard care. Within the subgroup of women with N gonorrhoeae, there was a substantial reduction in the primary outcome.

Gardnerella Vaginalis Bacteremia in a Pregnant Woman with Vaginal Myomectomy.

BACKGROUND: This case involves a 28-year-old pregnant woman (39w+2) who was admitted to obstetrics due to abdominal tightness and bacteremia with Gardnerella vaginalis which developed after caesarean section and vaginal myomectomy. METHODS: A blood culture was performed, and the bacteria were identified through mass spectrometry. RESULTS: Mass spectrometry data indicated that the infection bacteria were Gardnerella vaginalis. The patient's temperature returned to normal after oral ampicillin in combination with clindamycin. CONCLUSIONS: Gardnerella vaginalis bacteremia is very rare in clinical practice, and the combination of ampicillin and clindamycin has a good therapeutic effect. This study may provide a reference for the diagnosis and treatment of Gardnerella vaginalis bacteremia.

Lactobacillus crispatus CCFM1339 Inhibits Vaginal Epithelial Barrier Injury Induced by Gardnerella vaginalis in Mice.

The vaginal epithelial barrier, which integrates mechanical, immune, chemical, and microbial defenses, is pivotal in safeguarding against external pathogens and upholding the vaginal microecological equilibrium. Although the widely used metronidazole effectively curtails Gardnerella vaginalis, a key pathogen in bacterial vaginosis, it falls short in restoring the vaginal barrier or reducing recurrence rates. Our prior research highlighted Lactobacillus crispatus CCFM1339, a vaginally derived Lactobacillus strain, for its capacity to modulate the vaginal epithelial barrier. In cellular models, L. crispatus CCFM1339 fortified the integrity of the cellular monolayer, augmented cellular migration, and facilitated repair. Remarkably, in animal models, L. crispatus CCFM1339 substantially abated the secretion of the barrier disruption biomarker E-cadherin (from 101.45 to 82.90 pg/mL) and increased the anti-inflammatory cytokine IL-10 (35.18% vs. the model), consequently mitigating vaginal inflammation in mice. Immunological assays in vaginal tissues elucidated increased secretory IgA levels (from 405.56 to 740.62 ng/mL) and curtailed IL-17 gene expression. Moreover, L. crispatus CCFM1339 enhanced Lactobacilli abundance and attenuated Enterobacterium and Enterococcus within the vaginal microbiome, underscoring its potential in probiotic applications for vaginal barrier regulation.

The efficacy of vaginal treatment for non-Lactobacillus dominant endometrial microbiota-A case-control study.

AIM: Reduced Lactobacillus occupancy in the uterine microflora has been associated with implantation failure. This study aimed to evaluate a treatment for improving the uterine microflora. METHODS: This study included patients diagnosed with repeated implantation failure-defined as failure to achieve pregnancy after two or more transfers of viable embryos-who were classified as non-Lactobacillus dominant. Treatment A comprised oral administration of antibiotics for 1 week, followed by oral probiotic butyrate tablets (3 g/day) for approximately 30 days. Treatment B comprised a 1-week course of oral (750 mg/day) and vaginal (250 mg/day) metronidazole, followed by a 1-week intravaginal administration of probiotic capsules (1 capsule/day) and continued oral administration of probiotics (1 capsule/day). Both treatments were compared in terms of efficacy in improving vaginal flora. Improvement was defined as Lactobacillus occupancy >90% or an increase in Lactobacillus occupancy >20%. RESULTS: Seven (41.2%) of 17 patients in the Treatment A group improved in response to the treatment. Contrastingly, 9 (90.0%) of 10 patients improved in the Treatment B group (p = 0.0127). Following treatment, Lactobacillus occupancy in the Treatment B group (62.9% ± 12.7%) was significantly higher than that in the Treatment A group (5.7% ± 9.8%) (p = 0.0242). CONCLUSIONS: This study demonstrates the effectiveness of combining antibiotics and probiotics in vaginal formulations for treating abnormal uterine microflora. However, its potential impact on in vitro fertilization outcomes remains unclear and warrants further investigation through larger, more comprehensive studies.

The Folkloric Practices of Dominican Women in Managing Bacterial Vaginosis.

Bacterial vaginosis (BV) is characterized by changes in the vaginal flora caused by an elevated pH, resulting in symptoms of vaginal discharge, odor, and irritation. BV affects all women, including Dominican women who have specific cultural beliefs regarding vaginal health hygiene. Due to the prevalence of this condition and cultural norms that may influence how women respond to the diagnosis of BV, it is important to understand the factors that may promote the development of BV and that may influence women's choices of treatment options. Amsel's criteria are the most commonly used clinical approach for the diagnosis of BV. Recurrent BV is common and affects women's lives to varying degrees. Discussion about cultural norms and hygienic practices may provide information that may decrease the recurrence of BV. Nurses can provide support and evidence-based information in a culturally sensitive manner to help Dominican women manage BV.

Recurrent Infectious Vaginitis: A Practical Approach for the Primary Care Clinician.

Recurrent infectious vaginitis can lead to significant morbidity, patient frustration, and health care costs. The most common causes are bacterial vaginosis (BV) and vulvovaginal candidiasis (VVC); however, other infectious and noninfectious etiologies should be considered in patients with recurrent symptoms. A detailed history and physical examination with appropriate testing at the time of symptoms is critical to establishing a correct diagnosis. Management options for recurrent BV and VVC are limited. Complex cases including those with atypical symptoms, negative testing for common causes, refractory symptoms despite appropriate therapy or recurrences during suppressive therapy will require referral to specialist care.

VagiBIOM Lactobacillus suppository improves vaginal health index in perimenopausal women with bacterial vaginosis: a randomized control trial.

Bacterial vaginosis (BV) can cause vaginal dysbiosis that may influence general vaginal health and pregnancy complications. Balancing vaginal microbiome using Lactobacillus spp. may be a new way to prevent and treat mild BV. We conducted a randomized, double-blind, placebo-controlled pilot study aimed at evaluating the effect of the product VagiBIOM, a multi-Lactobacillus vaginal suppository, on peri- and premenopausal women with BV in restoring vaginal pH and overall vaginal health by resetting the vaginal microbiome composition. Sixty-six peri- and premenopausal women with BV symptoms were randomized with a 2:1 ratio to be treated with VagiBIOM or placebo suppositories. Vaginal pH, VAS itching score, total Nugent score, and vaginal health index (VHI) were measured. Vaginal microbiome changes before and after the treatment were analyzed by 16S rRNA sequencing and bioinformatics analysis. After 4 weeks of intervention with VagiBIOM or a placebo, the mean score for vaginal pH, VAS itching, and total Nugent score was significantly decreased from the baseline. Compared to the baseline scores, the VHI scores improved significantly following 28-day intervention (p < 0.001). Our results revealed two Lactobacillus species, L. hamsteri, and L. helveticus, as indicator species occurring differentially in the VagiBIOM-treated group. Furthermore, the regression and species network analyses revealed significant bacterial associations after VagiBIOM treatment. Lactobacillus hamsteri was positively associated with the Nugent score and negatively associated with vaginal pH. L. iners and L. salivarius were positively and inversely associated with VHI. As is typical, Bacteroides fragilis was positively associated with vaginal pH and negatively associated with the Nugent score. Interestingly, the Lactobacillus spp. diversity improved after VagiBIOM treatment. The VagiBIOM suppository treatment for peri- and premenopausal women with BV significantly relieved vaginal itching by decreasing vaginal pH and Nugent scores and improving the overall VHI after 4 weeks' intervention. This effect was primarily the result of VagiBIOM improving vaginal Lactobacillus diversity.Trial Registration ClinicalTrials.gov registration: NCT05060029, first registration 09/28/2021: Title: A Pilot Study to Evaluate the Efficacy and Safety of Lactobacillus Species Suppositories on Vaginal Health and pH.

Non-antibiotic Treatment Modalities for Bacterial Vaginosis.

Caused by an imbalance in the vaginal microbiome, bacterial vaginosis (BV) is among the most commonly occurring vaginal infections in women of childbearing age. If untreated, BV may have a detrimental impact on the obstetric and gynecological health of an individual. To date, treatment for BV includes a regimen of antibiotics and avoidance of relevant risk factors. Since recurrence and reinfection are frequently observed in patients, pharmaceutical treatment for BV remains ineffective nevertheless. Repeated exposure to antibiotics could precipitate drug-resistant strains. The severity of this problem leads to the emergence of non-antimicrobial therapies. This article aims to provide a review on the types and efficacy of various alternative, non-antimicrobial therapeutic regimens.

Metronidazole loaded chitosan-phytic acid polyelectrolyte complex nanoparticles as mucoadhesive vaginal delivery system for bacterial vaginosis.

Bacterial vaginosis (BV) is a recurring infection that is difficult to treat due to the limited bioavailability of antimicrobials. In this study, Metronidazole (MTZ)-loaded chitosan nanoparticles (MCSNP) were synthesized employing phytic acid (PA) as a crosslinking agent for treating bacterial vaginosis. The prepared MCSNPs were characterized for size, shape, surface charge, compatibility, cytotoxicity, biofilm inhibition, and in-vitro/in-vivo antimicrobial activities. Morphological examination revealed that nanoparticles generated from 0.535 % w/v chitosan and 0.112 % w/v PA were non-spherical, discontinuous, and irregular, with zeta potential ranging from 25.00 ± 0.45 to 39 ± 0.7. The results of DSC and XRD demonstrated no change in the physical state of the drug in the finished formulation. The optimized formulation demonstrates a cumulative drug release of about 98 ± 1.5 % within 8 h. Antimicrobial studies demonstrated that the optimized formulation had enhanced efficacy against acid-adapted BV pathogens, with a MIC value of 0.9 ± 0.1 µg/mL. Compared to the MTZ alone, the in-vivo antibacterial results of in the case of developed nanoparticles showed a four-fold reduction in bacterial count in female Swiss albino mice. Based on the experimental findings, it was concluded that MCSNPs, due to their excellent physiochemical and antibacterial properties, could serve as a potential topical alternative for treating BV.

The Association Between Human Immunodeficiency Virus and Bacterial Vaginosis and Metronidazole Treatment Failure for Trichomonas vaginalis.

BACKGROUND: Trichomonas vaginalis (TV) is a common sexually transmitted infection. High rates of repeated infections have been observed, particularly among women living with human immunodeficiency virus (HIV). Trichomonas vaginalis frequently cooccurs with bacterial vaginosis (BV). The purpose of this study was to determine if coinfections with TV, BV, and HIV could lead to differential treatment failure outcomes. METHODS: Data were pooled from 2 prior randomized control trials comparing 2 g oral single-dose versus 500-mg twice daily oral 7-day dose metronidazole for the treatment of TV in HIV infected and HIV uninfected women. Trichomonas vaginalis rates 1-month postcompletion of treatment were compared by arm, HIV and BV status after removing those who had sexual reexposure, and/or did not complete their treatment. RESULTS: Data for 795 subjects were included in the study, of which 76 (9.6%) experienced treatment failure. In the final multivariable model, which included treatment dose, HIV status, and BV status, odds of treatment failure infection in the 7-day dose group were lower than the odds in the single dose group (odds ratio, 040; 95% confidence interval, 0.23-0.68). Treatment failure was lower in the multidose arm compared with single dose for both HIV-infected (4.0% vs 10.3%; P = 0.0568) and HIV-uninfected (7.3% vs 15.4%; P = 0.0037). Neither HIV nor BV was associated with higher treatment failure. CONCLUSIONS: Human immunodeficiency virus infection and BV status did not significantly alter the rate of repeat infection for either single dose or 7-day dose metronidazole. Among all women, 7-day metronidazole lowered the odds of treatment failure.

Design and evaluation of antibacterials crosslinked chitosan nanoparticle as a novel carrier for the delivery of metronidazole to treat bacterial vaginosis.

Bacterial vaginosis (BV) is a recurring, chronic infection that is difficult to treat due to the limited bioavailability of antimicrobials within vaginal epithelial cells. Vaginal administration, because of lower dosing and systemic exposure offers a viable option for treating vaginal infections. In this study, Metronidazole-loaded chitosan nanoparticles were synthesised employing borax (BX) or tannic acid (TA) as an antimicrobial crosslinking agent for treating BV. The prepared NPs were characterized for various physical, physicochemical, pharmaceutical, thermal and antibacterial properties. Morphological investigation revealed that nanoparticles prepared from 0.5 % w/v chitosan, 1.2 % w/v BX, and 0.4 % w/v metronidazole (MTZ) were non-spherical, with particle sizes of 377.4 ± 37.3 nm and a zeta potential of 34 ± 2.1 mV. The optimised formulation has MIC values of 24 ± 0.5 and 59 ± 0.5 µg/mL, against Escherichia coli (E.coli) and Candida albicans (C.albicans) respectively. The results of DSC and XRD demonstrated no change in the physical state of the drug in the finished formulation. Under simulated vaginal fluid, the optimised formulation demonstrates a cumulative drug release of about 90 % within 6h. The prepared borax crosslinked NPs exhibit anti-fungal activities by inhibiting ergosterol synthesis. The in-vivo antibacterial data indicated a comparable reduction in bacterial count compared to the marketed formulation in female Swiss albino mice treated with optimised nanoparticles. According to histopathological findings, the prepared nanoparticle was safe for vaginal use. Based on the experimental findings, it was concluded that MBCSNPs, due to their good physiochemical and antimicrobial properties, could serve as a potential topical alternative for treating BV and reducing fungal infection.

Treatment patterns and economic burden of bacterial vaginosis among commercially insured women in the USA.

Aim: Bacterial vaginosis (BV) is a common vaginal dysbiosis associated with adverse clinical sequelae, most notably, increased risk of sexually transmitted infections (STIs). The aims of this study were to estimate the frequency of BV recurrence, treatment patterns, other gynecological (GYN) conditions, and the associated healthcare resource utilization (HCRU) and costs among commercially insured patients in the USA. Patients & methods: Female patients aged 12-49 years with an incident vaginitis diagnosis and ≥1 pharmacy claim for a BV medication (fungal treatment only excluded) were selected from the Merative™ MarketScan commercial database (2017-2020). During a minimum 12-month follow-up, additional treatment courses, treatment patterns, frequency of other GYN conditions, and HCRU and costs were assessed. Generalized linear models were used to identify baseline predictors of total all-cause healthcare costs and number of treatment courses. Results: The study population included 140,826 patients (mean age: 31.5 years) with an incident vaginitis diagnosis and ≥1 BV medication claim. During the follow-up, 64.2% had 1 treatment course, 22.0% had 2, 8.1% had 3, and 5.8% had ≥4; 35.8% had a BV recurrence (≥2 BV medication claims). The most commonly prescribed BV medication was oral metronidazole (73.6%). Approximately 12% (n = 16,619) of patients had a new diagnosis of another GYN condition in the follow-up; 8.2% had a new STI, which were more common among patients with ≥4 treatment courses (12.9%). During follow-up, total all-cause healthcare costs averaged $8987 per patient per year (PPPY) of which $470 was BV-related. BV-related healthcare costs increased from $403 PPPY among those with 1 treatment course to $806 PPPY among those with ≥4 with nearly half the costs attributed to outpatient office visits. Conclusion: BV recurrence among this population represented a substantial clinical and healthcare economic burden warranting improvements in women's healthcare.

Dequalinium Chloride for the Treatment of Vulvovaginal Infections: A Systematic Review and Meta-Analysis.

OBJECTIVE/PURPOSE: Women at reproductive age frequently experience vulvovaginal infections and vaginitis. The most common etiologies are vulvovaginal candidiasis (VVC), bacterial vaginosis (BV), desquamative inflammatory vaginitis/aerobic vaginitis, and trichomoniasis. Various treatment options are available for these infections, such as specific antimicrobial or antiseptic agents. Dequalinium chloride (DQC) is a local antiseptic agent with a broad antimicrobial and antifungal spectrum. Multiple studies suggest that DQC is an efficient treatment for vaginal infections; however, it is not widely recommended as a first-line treatment. This systematic review and meta-analysis aims to evaluate the efficacy of DQC compared with that of standard treatment. METHODS: Our systematic review was conducted according to the PRISMA guidelines. PubMed/MEDLINE, EMBASE, CENTRAL, and clinicaltrials.org were searched to retrieve relevant reports up to October 2022. RESULTS: Four randomized controlled studies and 1 observational study were included in this review. Overall, DQC showed noninferiority to the reference treatments for BV and VVC, and to the evaluated treatment options for desquamative inflammatory vaginitis/aerobic vaginitis. For BV and VVC, this could also be confirmed in a meta-analysis including 3 randomized controlled studies. No serious adverse events were reported in any of these studies. CONCLUSIONS: Dequalinium chloride offers a safe, well-tolerated, and efficient treatment option for vulvovaginal infections of different etiologies. However, further studies are needed to confirm our findings and allow inclusion of DQC as a first-line treatment into guidelines.

[Systematic review and Meta-analysis of efficacy and safety of Kushen Gelatum combined with antibiotics in treatment of bacterial vaginosis].

This study aims to systematically evaluate the clinical efficacy and safety of Kushen Gelatum combined with antibiotics for treating bacterial vaginosis. The randomized controlled trial(RCT) of Kushen Gelatum for treating bacterial vaginosis were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, and Cochrane Library with the time interval from inception to January 2023. Data were extracted from the included RCT by 2 investigators, including the sample size, characteristics of patients, interventions and controls, outcome indicators, and adverse effects. The Cochrane collaboration network's bias risk assessment tool was used for methodolo-gical quality evaluation of the included trials. RevMan 5.4 was employed to perform the Meta-analysis. A total of 19 RCTs were inclu-ded, involving 1 980 patients with bacterial vaginosis. Meta-analysis showed that, compared with nitroimidazoles alone, Kushen Gelatum + nitroimidazoles improved the total response rates in terms of clinical symptoms and laboratory tests(RR=1.24, 95%CI[1.13, 1.36], P<0.000 01), laboratory tests(RR=1.16, 95%CI[1.06, 1.26], P=0.000 9), and clinical symptoms(RR=1.26, 95%CI[1.08, 1.46], P=0.003), and reduced the leukocyte esterase positive rate(RR=0.29, 95%CI[0.17, 0.48], P<0.000 01) and the recurrence rate(RR=0.37, 95%CI[0.23, 0.58], P<0.000 1). Compared with lincomycin antibiotics(clindamycin) alone, Kushen Gelatum + lincomycin antibiotics(clindamycin) improved the total response rates in terms of clinical symptoms and laboratory tests(RR=1.18, 95%CI[1.06, 1.31], P=0.003) and laboratory tests(RR=1.27, 95%CI[1.04, 1.54], P=0.02), reduced the recurrence rate(RR=0.20, 95%CI[0.05, 0.75], P=0.02), and shortened the time to relief of burning sensation(MD=-1.70, 95%CI[-2.15,-1.26], P<0.000 01), vaginal itching(MD=-0.82, 95%CI[-1.30,-0.34], P=0.000 8), and abnormal leucorrhea(MD=-1.52, 95%CI[-1.98,-1.06], P<0.000 01). Compared with nitroimidazoles + probiotics, Kushen Gelatum + nitroimidazoles + probiotics improved the total response rate in terms of clinical symptoms and laboratory tests(RR=1.18, 95%CI[1.02, 1.36], P=0.03) and reduced the recurrence rate(RR=0.27, 95%CI[0.09, 0.76], P=0.01). Kushen Gelatum combined with antibiotics demonstrates a potential therapeutic effect on bacterial vaginosis, whereas the number and quality of the relevant clinical studies remain to be improved. The process of clinical trial should be standardized to improve the quality of evidence, so as to provide strong evidence to guide the application of Kushen Gelatum in clinical practice.

[Onto-phylogenetic prerequisites for development of chronic cystitis in women].

INTRODUCTION: Urinary tract infections (UTIs) are among the most common bacterial infections. At the request "cystitis", there are 12,067 publications in the RSCI system (e.library) as of 10/08/2023 and 16,332 articles were screened in the Pubmed. This is evidence that the problem of cystitis is far from being resolved. MATERIAL AND METHODS: A total of 425 patients with bacterial vaginosis and 77 women with chronic recurrent cystitis were included in the study. In all patients, the vaginal biocenosis was assessed through molecular genetic testing. The examination included filling out the Russian version of the Acute Cystitis Symptom Score (ACSS), urinalysis, and urine culture. In addition, local microcirculation was measured using laser Doppler flowmetry (LDF). After examination, patients were prescribed basic therapy and randomly assigned to one of three groups. In a control group (n=17), only basic therapy, consisting of fosfomycin 3.0 once at night + furagin 100 mg after meals 3 times a day for 5 days was prescribed. In the main group 1, 29 women received basic therapy plus Superlymph suppositories 10 units 2 times a day vaginally for 10 days. In the main group 2, 31 patients received basic therapy plus suppositories Superlymph 10 units (rectally in the morning) and Acylact Duo (vaginally in the evening) for 10 days. RESULTS: Among 425 patients with bacterial vaginosis, 78 (18.3%) complained of various urinary disorders, but only 21 women (4.9% of those with vaginal dysbiosis and 26.9% with dysuria) had a diagnosis of cystitis. In all cases, it was an exacerbation of a chronic disease. Among 77 patients with chronic cystitis, normal vaginal flora was initially present in 32 patients (41.6%), and bacterial vaginosis was found in 45 (58.4%) cases. After therapy, positive results were noted in patients of all groups. Complete eradication of the pathogen occurred in 15 women (88.2%) who received only basic therapy; in the main groups 1 and 2, uropathogens were not detected in 27 (93.1%) and 28 (90.3%) cases, respectively. In the control group, the proportion of patients with normal vaginal flora remained virtually unchanged (41.2% [n=7] vs. 47.1% [n=8]). In the main group 1, the proportion of patients with normal vaginal flora almost doubled: from 41.4% (n=12) to 79.3% (n=23). In main group 2, restoration of vaginal flora was noted in 87.1% of cases. CONCLUSION: According to our data, only 4.9% of patients with bacterial vaginosis were diagnosed with chronic cystitis, however, 58.4% of patients with chronic cystitis had vaginal dysbiosis. The use of a complex of antimicrobial peptides and cytokines has significantly increased the bidirectional effect of therapy. Suppositories Superlymph in a combination with vaginal use of Acylact Duo allow to obtain the best results.
