povidone-iodine and Vaginal-Discharge

Abnormal vaginal discharge (AVD) caused by a variety of reproductive tract infections is a widespread syndrome among women in India and in other developing countries. The purpose of this study was to determine whether a polyherbal formulation, Praneem, can be used for the regression of the syndrome. A phase IotaIota randomized controlled study was carried out with Praneem polyherbal tablets and Betadine vaginal pessary in 99 women with AVD. The authors found that 92% of women using Praneem were relieved of their symptoms of AVD as against 81.6% women using Betadine. Significant reduction was also seen with both treatments in lower abdominal pain, vaginal itching, and dysuria. Thus, the study indicates the efficacy of Praneem for the treatment of AVD and provides a rationale for planning a further Phase III study on a larger sample size for definitive conclusions.

This randomised, double-blind, multicentric clinical study compared the efficacy and tolerability of the two vaginal antiseptics, 10 mg dequalinium chloride (CAS 522-51-0, Fluomycin N) and 200 mg povidone iodine (CAS 25655-41-8), in a parallel-group design. A total of 180 patients with vaginal infections of varying etiology participated in this study (bacterial vaginosis, fluor vaginalis, vulvo-vaginal candidiasis, trichomoniasis). Patients were randomly allocated to one of the two treatment groups and were treated once per day for 6 days. Control examinations took place 5 to 7 days after the end of treatment, and 3 to 4 weeks after the first control examination. The total symptoms score, a summary score for the clinical symptoms, discharge, burning, pruritus, redness of vulva/vagina, was defined as primary efficacy parameter. The treatments at the first control examination were compared in the full analysis set using the Wilcoxon-Mann-Whitney U-test, 2-sided, thereby proving equivalence of both treatments at the 5% level. Both treatments strongly improved the symptoms of vaginal infections both on short-term and long-term follow-up. Descriptive analysis of the secondary parameters, vaginal pH, degree of purity of the vaginal flora, and number of lactobacilli in the wet mounts, supported the comparable efficacy of both therapies to restore the vaginal milieu. Analysis of the diagnostic subgroups indicated that irrespective of the diagnosis, both treatments improved the efficacy criteria as observed for the entire population. The global assessment of the therapeutic efficacy by investigators and patients supported the results of the efficacy analysis with good to very good ratings in 70-90% of the cases. A good tolerability of both preparations was observed in this study with a low number of adverse events in the test group (5.8%).

This study aimed to assess the in vitro antimicrobial effects of chlorhexidine (CHX) and povidone-iodine (PI) on clinical isolates of Escherichia coli (E. coli) and Trueperella pyogenes (T. pyogenes) from the vaginal discharge of dairy cows, as well as to compare the cytotoxicity effects of CHX and PI on bovine endometrial epithelial cells (BEnEpC). In Experiment 1, 12 E. coli and 10 T. pyogenes were isolated from the vaginal discharge of cows with a uterine infection. The MIC and MBC against CHX and PI were analyzed in vitro. In Experiment 2, the cytotoxicity effects of CHX and PI on BEnEpC were analyzed using a Viability/Cytotoxicity Kit, wound scratch healing assay, and the expression of pro-inflammatory cytokine genes (IL-6, IL-8, and TNF-α). In Experiment 1, the MIC and MBC values of CHX against E. coli were 0.0002% and 0.0002 to 0.00025%, respectively. The MIC and MBC values of PI were 1.25 to 2.5% and 1.25 to 5%, respectively. For T. pyogenes, the MIC and MBC values of CHX were 0.00002%. The MIC and MBC values of PI were 1.25%. In Experiment 2, the cell viability significantly decreased, and wound closures were significantly inhibited after treatment with ≥ 0.002% CHX and ≥ 0.025% PI. The expression of IL-6, IL-8, and TNF-α significantly increased after treatment with PI. Only IL-6 showed a significant increase after cells were treated with 0.00002% and 0.0002% CHX. The results suggested that both CHX and PI had high antibacterial effects. However, veterinarians and farmers should be aware of their cytotoxicity, which decrease viability of endometrial epithelial cells and inhibit wound healing in vitro.
