Bacterial vaginosis (BV) is the most common vaginal infection affecting women of childbearing age, and is associated with a substantial burden on women's physical, emotional, sexual and social lives, as well as being linked to a number of gynaecological and obstetrical complications and adverse pregnancy outcomes. Antibiotics, such as metronidazole or clindamycin, are recommended as first-line treatment for BV, but may be associated with antibiotic resistance, high rates of recurrence and poor patient treatment satisfaction. Astodrimer sodium gel is a novel, non-antibiotic treatment for BV that is not systemically absorbed. It prevents pathogenic bacteria from adhering to the vaginal wall, and disrupts and inhibits the formation of pathogenic bacterial biofilms. Clinical cure rates of 50-57% were observed in patients with BV treated with astodrimer sodium compared with 17-21% treated with placebo (p < 0.001) in Phase 3 trials. In a separate Phase 3 trial, recurrence of BV occurred in 44% of patients treated with astodrimer sodium compared with 54% of patients who received placebo (p = 0.015). Astodrimer sodium is well tolerated, with vulvovaginal candidosis being the only treatment-related adverse event reported to occur more often than with placebo. The availability of astodrimer sodium, a well-tolerated, convenient, non-antibiotic treatment for BV, represents significant progress in the treatment of this burdensome condition., (© 2022.

Purpose: The main objective of this open, prospective, multicentre, observational study is to investigate the relapse rate and tolerability of lactic acid gels in adult female patients with recurrent urinary tract infections during routine practice., Methods: Data were collected from patients undergoing intermittent short courses of intravaginal treatment with lactic acid gel for prevention of recurrent urinary tract infections. The observation period for individual patients was 4 months, aimed at covering four short courses of intravaginal treatment. Data on UTI relapses, tolerability, handling and satisfaction with the treatment were collected via patient diaries and physician assessments and comprised any adverse events (AEs)., Results: In total, 72 patients were treated. During the last 12 months prior to the study, patients had on average 4.0 UTIs. In the 4 months after commencing treatment, 63.5% of patients had no recurrence of UTI symptoms. Overall efficacy was rated by physicians as 'excellent/good' for 96.7% of patients. The patients' overall acceptance of local treatment was high with 94.1% being '(very) satisfied'. Similarly, handling was rated as '(very) easy' by 94.2% of patients. The tolerability was assessed as 'highly tolerable/tolerable' by over 98% of patients and physicians alike. Safety analyses reported six AEs of mild intensity, all of which had resolved by the end of the study., Conclusion: Treatment with lactic acid gel may increase resilience against uropathogens, possibly preventing the need for antibiotic prevention of recurrent urinary tract infections. Treatment was positively assessed by the patients. The physician assessments corroborate these findings., Trial Registration Number and Date of Registration: DRKS00016760, 18.02.2019., (© 2021.

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: Vaginal infections are responsible for a large proportion of gynaecological outpatient visits. Those are bacterial vaginosis (BV), vulvovaginal candidosis (VVC), aerobic vaginitis (AV) associated with aerobic bacteria, and mixed infections. Usual treatments show similar acceptable short-term efficacy, but frequent recurrences and increasing microbial resistance are unsolved issues. Furthermore, vaginal infections are associated with a variety of serious adverse outcomes in pregnancy and generally have a major impact on quality of life. Identifying the correct therapy can be challenging for the clinician, particularly in mixed infections., Findings: Dequalinium chloride (DQC) is an anti-microbial antiseptic agent with a broad bactericidal and fungicidal activity. Systemic absorption after vaginal application of DQC is very low and systemic effects negligible. Vaginal DQC (Fluomizin vaginal tablets) has been shown to have equal clinical efficacy as clindamycin in the treatment of BV. Its broad antimicrobial activity makes it appropriate for the treatment of mixed vaginal infections and in case of uncertain diagnosis. Moreover, resistance of pathogens is unlikely due to its multiple mode of action, and vaginal DQC provides also a reduced risk for post-treatment vaginal infections., Conclusions: Vaginal DQC (10 mg) as 6-day therapy offers a safe and effective option for empiric therapy of different vaginal infections in daily practice. This review summarizes the available and relevant pharmacological and clinical data for the therapy of vaginal infections with vaginal DQC and provides the rationale for its use in daily gynaecologic practice.

Objective: We tested the effect of vaginally applied lactic acid gel on symptoms and bacteriuria in acutely exacerbated recurrent Eschericia coli cystitis., Methods: Carnoy fixed samples of the morning urine from 20 women with a history of recurrent E.coli cystitis were prospectively investigated for bacteriuria using fluorescence in situ hybridization (FISH)., Results: In 11/20 women with acute cystitis, the symptoms and bacteriuria were regressive with lactic acid gel treatment, without the need for antibiotic treatment. The complete regression of symptoms took between 1 week (7 women) and 4 weeks (4 women). In parallel with this regression, the microscopic shape of E.coli bacteria in these women changed from short rods to long curly filaments starting within the first days of therapy. The filamentous transformation affected 100% of the E.coli population in six women and at least 50% of E.coli population in five women and was not observed in urine samples from untreated women or in women without clinical response to lactic acid gel. This could not happen if the bladder was the origin of the infection., Conclusions: A number of recurrent and probably acute cystitis is a local vagino-urethritis caused by an adhesive invasive E.coli biofilm of the vaginal surface.
