povidone-iodine and Vaginosis--Bacterial

Underwater plasma discharge temporally produces several reactive radicals and/or free chlorine molecules in water, which is responsible for antimicrobial activity. Hence, it can simply sanitize tap water without disinfectant treatment. Additionally, the spraying technique using cleaning water exploits deep application in the narrow and curved vaginal tract of patients. Herein, we attempted a clinical trial to evaluate the vaginal cleaning effect of spraying plasma-activated water (PAW) to patients with vaginitis (46 patients). The efficacy was compared with treatment with betadine antiseptics used to treat bacterial vaginosis (40 patients). To evaluate the cleaning effect, Gram staining of the vaginal secretions was conducted before and after spraying PAW or betadine treatment (BT). Consequently, PAW-sprayed (PAWS) patients (22.3%) showed a better vaginal cleaning effect against Gram-positive and -negative bacteria than BT patients (14.4%). Moreover, 18 patients in the BT group showed worsened vaginal contamination, whereas five patients in the PAWS group showed worsened vaginal contamination. Taken together, the noncontact method of spraying cleaning water to the vagina exhibited a reliable vaginal cleaning effect without further bacterial infection compared with BT. Therefore, we suggest a clinical application of the spraying method using PAW for vaginal cleaning to patients with vaginitis without disinfectants and antibiotics.

A prospective, randomized clinical trial was performed to study the efficacy of povidone iodine (Betadine) suppositories for the treatment of bacterial vaginosis (BV) in comparison to capsules containing lactobacilli (Döderlein Med). Seventy patients with BV included in the study were randomly assigned to be either treated with povidone iodine suppositories or lactobacilli. Patients were treated once a day for 5 days. Initial examinations took place on the first day of the study with follow-up examinations on days 8 and 15. The examinations included clinical parameters, patient evaluation, secretion screens, and quantitative and qualitative microbiological tests of vaginal flora. Both treatment groups showed improvement of clinical parameters, condition of secretions and subjective state of health. At day 15 there was a trend towards a better efficacy of the treatment with povidone iodine but this was not significant. However, patients with acute BV treated with povidone iodine had significantly better scores after 15 days. Both treatments were well tolerated. The microbiological examinations showed an increase of the mean number of lactobacilli in the vagina on day 8 after initiation of treatment with lactobacilli, but a decrease on day 15. Contrary to that the lactobacilli counts from patients treated with povidone iodine suppositories decreased after the first week but increased in the second one. Potentially pathogenic germs, e.g. Gardnerella, Bacteroides and Enterobacteria were reduced in a higher extent and with a longer lasting effect after treatment with povidone iodine suppositories than with capsules containing lactobacilli. The results of this study show that native lactobacilli rapidly re-colonize after the antiseptic treatment with povidone iodine. Therefore, there is no need to use lactobacilli in addition.

Recent evidence has associated bacterial vaginosis and trichomoniasis with several postoperative complications. We carried out a prospective study aiming to estimate the frequency of vaginitis in women wanting to make an artificial abortion and the possibility to influence this infections by local application of vaginal BETADINE suppositories in all forms of infectious vaginitis: Candida albicans, trichomonas vaginalis and bacterial vaginosis.

Bacterial vaginosis is a frequent dysbiosis, where the normal lactobacillus-dominated flora is replaced by an anaerob/aerob polymicrobial flora. Bacterial vaginosis increases the risk of acquiring sexually transmitted infections (STI) including the most frequent Chlamydia trachomatis infections. Intravaginal antiseptics are part of the bacterial vaginosis treatment, and ideally they should also inhibit the bacterial vaginosis-related STI. Therefore, we tested the antichlamydial activity of four antiseptics: iodine aqueous solution, povidone-iodine, chlorhexidine and borax. First, we measured the impact of antiseptics on the viability of the HeLa cervical epithelial cells, and calculated the maximum nontoxic concentrations. Next, we infected the cells with C. trachomatis preincubated for 1 h with the particular antiseptic. The chlamydial growth was measured by direct quantitative PCR (qPCR) of the infected cells. The minimal inhibitory concentrations (MIC) of chlorhexidine and povidone-iodine were 3·91 and 97 μg ml(-1) respectively; however, the MIC of chlorhexidine was close to its maximum nontoxic concentration. The iodine aqueous solution and the borax showed no antichlamydial activity. Our in vitro studies showed that chlorhexidine and particularly povidone-iodine are potentially able to limit the bacterial vaginosis-related C. trachomatis infection.. We measured the antichlamydial effects of various antiseptics. These antiseptics are being used for the treatment of bacterial vaginosis, but their effect on the bacterial vaginosis-related sexually transmitted infections, particularly the most frequent Chlamydia trachomatis (C. trachomatis) infections has not been investigated. We showed that povidone-iodine (Betadine) inhibited the chlamydial growth in concentrations that was not toxic to the epithelial cells. We concluded that due to its additional antichlamydial effect, povidone-iodine could be a preferable antiseptic in bacterial vaginosis treatment.
