Filter by:Study question: Does antibiotic alone or in combination with live biotherapeutic treatment of an abnormal vaginal microbiota improve the reproductive outcomes of IVF couples? Study hypothesis: The investigator hypothesize that treatment of the reproductive tract pathogens and restoration of vaginal Lactobacillus will improve the reproductive outcomes of IVF patients. What is known already? Ultra-deep sequencing methods enable the refinement of reproductive tract microbiology in infertile patients. A recent meta-analysis reported that 19% of infertile patients had abnormal vaginal microbiota Moreover, someone have detected the presence of a Gardnerella (G.) vaginalis dominated endometrial biofilm in 50% of non-infertile patients with abnormal vaginal microbiota undergoing curettage; thus the treatment of such an endometrial biofilm might play an important role for the endometrial receptivity and subsequently the clinical pregnancy rate. Pilot study: In a recent pilot study it was observed that an abnormal vaginal microbiota negatively affects the clinical pregnancy rate in IVF patients. In this study the prevalence of abnormal vaginal microbiota was 28% (36/130) and only 9% of patients with qPCR defined abnormal vaginal microbiota obtained a clinical pregnancy (p=0.004). This association remained significant in an adjusted analysis. Furthermore, the invetigators have preliminary results demonstrating that vaginal bacteria such as G. vaginalis can be found in the endometrium of IVF patients, which is also supported by recent publications What is the novelty of this study? To the investigators knowledge, no previous treatment study of abnormal reproductive tract microbiota has been performed in IVF patients; this relatively small intervention holds the potential to increase the baby-take-home rate after IVF treatment.
Previous research has shown that semen deposition in the vagina after intercourse leads to dripping, discomfort, and vaginal odor. This study is evaluating a hygiene device designed to be inserted into the vagina after intercourse to absorb semen deposited into the vaginal canal to determine if there is a reduction in dripping and odor, and to determine the amount of fluids absorbed.
This is a randomized, double-blind, placebo-controlled clinical investigation. The objective of the study is to confirm the efficacy of Multi-Gyn ActiGel Plus to treat BV as compared to a placebo control. Treatment arm 1: Multi-Gyn ActiGel Plus Treatment arm 2: placebo gel Both the Multi-Gyn ActiGel Plus and the placebo will be applied twice a day for 7 consecutive days. Visit 2 will be performed at 3 weeks after start of treatment A phone call will take place, at 5 weeks after start of treatment for subject with clinical cure at Visit 2. The total duration per subject is estimated 5 weeks and the total study duration is 13 months. Sample size is 100 subjects per treatment arm.
Vaginal Microbiome Transplantation (VMT) may be beneficial in treating the most severe cases of recurrent and antibiotics-nonresponsive cases of BV. Recently, we completed a preliminary study in which we treated patients with recurrent and antibiotics-non-responsive, intractable BV, with VMT from healthy donors [Lev-Sagie, Nature Medicine 2019]. Four VMT recipients in this preliminary study featured a significant improvement of both clinical symptoms and dysbiotic vaginal microbiome composition and function, which persisted over a long follow-up period, while one recipient featured a partial remission. The proposed study is designed as a placebo, randomized controlled trial, and is aimed to further assess whether VMT may serve as a viable option in symptomatic, intractable BV. In the suggested study, we plan to compare transplantation of: 1) vaginal fluid from healthy donors, and 2) autologous transplantation, of the patient's own vaginal fluid.
