Perspectives on Existing and Novel Alternative Intravaginal Probiotic Delivery Methods in the Context of Bacterial Vaginosis Infection.

AAPS J 2021 May 10;23(3):66. Epub 2021 May 10.

Center for Predictive Medicine, University of Louisville, Louisville, Kentucky, USA.

Bacterial vaginosis (BV) is one of the most common vaginal infections that affects hundreds of millions of women of reproductive age, worldwide. Traditional treatment strategies, such as oral and topical antibiotics, have shown efficacy against BV, but frequent recurrence of infection and the development of antibiotic-resistant bacteria remain as significant challenges. Alternatively, recent progress in understanding immune, microbiological, and metabolic interactions in the vaginal microbiota has prompted the consideration of administering probiotic organisms to restore and maintain vaginal health within the context of BV prevention and treatment.

Vaginal Probiotics for Reproductive Health and Related Dysbiosis: Systematic Review and Meta-Analysis.

J Clin Med 2021 Apr 2;10(7). Epub 2021 Apr 2.

Department of Microbiology, Faculty of Pharmacy, Campus of Cartuja, University of Granada, 18071 Granada, Spain.

The use of probiotics in reproductive-related dysbiosis is an area of continuous progress due to the growing interest from clinicians and patients suffering from recurrent reproductive microbiota disorders. An imbalance in the natural colonization sites related to reproductive health-vaginal, cervicovaginal, endometrial, and pregnancy-related altered microbiota-could play a decisive role in reproductive outcomes. Oral and vaginal administrations are in continuous discussion regarding the clinical effects pursued, but the oral route is used and studied more often despite the need for further transference to the colonization site.

Department of Microbiology, Immunology and Parasitology, Louisiana State University Health Sciences Center, New Orleans, LA, United States.

studies indicate IFNγ is central to (Ct) eradication, but its function may be compromised by anaerobes typically associated with bacterial vaginosis (BV), a frequent co-morbidity in women with Ct. Here we investigated the associations between natural clearance of cervical Ct infection, the vaginal microbiome, and the requirements for IFNγ by evaluating the vaginal microbial and cytokine composition of Ct treatment visit samples from women who cleared Ct infection in the interim between their Ct screening and Ct treatment visit. The pilot cohort was young, predominantly African American, and characterized by a high rate of BV that was treated with metronidazole at the Ct screening visit. Read More

Development and evaluation of a Point-of-Care Test (POCT) in a low resource setting with high rates of urogenital infections in Fiji.

J Clin Microbiol 2021 Apr 28. Epub 2021 Apr 28.

Lucira Health, Emeryville, CA, USA

Rapid and precise detection of -the leading global cause of sexually transmitted infections (STI)-at the point-of-care (POC) is required for treatment decisions to prevent transmission and sequelae including pelvic inflammatory disease, ectopic pregnancy, tubal-factor infertility and preterm birth. We developed a rapid POC test (POCT), termed LH-POCT, which uses Loop-mediated AMPlification (LAMP) of nucleic acids, and performed a head-to-head comparison with the Cepheid Xpert® CT/NG assay using clinician-collected de-identified paired vaginal samples from a parent study that consecutively enrolled symptomatic and asymptomatic females over age 18 years from the Ministry of Health and Medical Services Health Centers in Fiji. Samples were processed by the Xpert® CT/NG assay and LH-POCT, blinded to the comparator. Read More

Oral administration of Lactobacillus crispatus M247 to papillomavirus-infected women: results of a preliminary, uncontrolled, open trial

Minerva Obstet Gynecol 2021 04 20. Epub 2021 Apr 20.

Section of Gynecology, Academic Department of Biomedicine and Prevention and Clinical Department of Surgery, Tor Vergata University Hospital, Rome, Italy.

Background: Vaginal microbiotas can be clustered into five different possible categories (CST I to V), according to their bacterial dominance. In CST I, the dominance of Lactobacillus crispatus seems to correlate with better vaginal health and with a lower incidence of sine causa infertility, preterm delivery, bacterial vaginosis, and viral (including human papillomavirus; HPV) infection. According to the same method of classifying the vaginal microbiome, CST IV (non-Lactobacillusdominated) demonstrates a higher incidence of disorders. Read More
