Bacterial vaginosis (BV) is the most common vaginal dysbiosis. In this condition, a polymicrobial biofilm develops on vaginal epithelial cells. Accurately quantifying the bacterial burden of the BV biofilm is necessary to further our understanding of BV pathogenesis. Historically, the standard for calculating total bacterial burden of the BV biofilm has been based on quantifying Escherichia coli 16S rRNA gene copy number. However, E. coli is improper for measuring the bacterial burden of this unique micro-environment. Here, we propose a novel qPCR standard to quantify bacterial burden in vaginal microbial communities, from an optimal state to a mature BV biofilm. …

A Comparison Of Single-Dose Versus Divided-Dose Of Metronidazole On Bacterial Vaginosis Among Female Sex Workers In Surakarta, Willa Damayanti, Rini Hastuti, Agung Triana, Danu Yuliarto, Ardelia Dyah Ayu, Endra Yustin Ellistasari

Journal of General - Procedural Dermatology & Venereology Indonesia

Background: Bacterial vaginosis (BV) is the most common vaginal infection in sexually active women. Metronidazole (MTZ) is still one of the recommended regimens for BV either as a single-dose or divided-dose. In addition to its affordability and availability, oral metronidazole also produces fewer adverse effects. This study aimedto determine the efficacy of single-dose versus divided-dose metronidazole for BV among female sex workers (FSWs) in Surakarta.

Methods: A single-blind randomized clinical trial was conducted in Surakarta. FSWswith BV (⩾3 Amsel criteria) were enrolled. The subjects were grouped into two, and treated with MTZ either as a single-dose of …

Prevalence And Risk Factors Of Bacterial Vaginosis Among Female Sex Workers In Surakarta, Rini Hastuti, Danu Yuliarto, Agung Triana, Willa Damayanti, Rakhma Tri Irfanti, Mardiana Mardiana, Putti Fatiharani Dewi, Ambar Aliwardani, Ervianti Abas, Sulistyo Sulistyo, Prasetyadi Mawardi, Endra Yustin Ellistasari

Journal of General - Procedural Dermatology & Venereology Indonesia

Background: Bacterial vaginosis (BV) is the most common vaginal infection in women of reproductive age and increases the risk of acquiring human immunodeficiency virus (HIV) and other sexually transmitted diseases (STDs). Data regarding the association between sexual activity and BV acquisition is contradictory. Thus, tracking the prevalence and associated risk factors of BV among female sex workers (FSWs) is necessary to improve our understanding and control of STDs and the HIV epidemic.

Methods: The subjects of this study were FSWs in Surakarta. This study adopted a cross-sectional design, and diagnosis was established using Amsel criteria. Interviews were conducted …

Vaginal Microbiota In Menopause, Martinus Martinus, Larisa Paramitha Wibawa, Evita Halim Effendi, Shannaz Nadia Yusharyahya, Hanny Nilasari, Wresti Indriatmi

Journal of General - Procedural Dermatology & Venereology Indonesia

The human vagina together with its resident, microbiota, comprise a dynamic ecosystem. Normal microbiota is dominated by Lactobacillus species, and pathogen microbiota such as Gardnerella species and Bacteroides species can occur due to decrease in Lactobacillus domination. Lactobacillus plays an essential role in keeping normal vaginal microbiota in balance. Vaginal microbiota adapts to pH change and hormonal value. Changes in the vaginal microbiota over a woman’s lifespan will influence the colonization of pathogenic microbes. They include changes in child, puberty, reproductive state, menopause, and postmenopause. Estrogen levels change will affect the colonization of pathogenic microbium, leading to genitourinary syndrome of …

Characterisation Of The Vaginal Microflora Of Human Immunodeficiency Virus (Hiv) Positive And Negative Women In A Sub-Urban Population Of Kenya, Teresa N. Kiama, Rita Verhelst, Paul M. Mbugua, Mario Vaneechoutte, Hans Verstraelen, Benson Estambale, Marleen Temmerman

Lactobacilli predominate normal vaginal microflora and are important in maintenance of vaginal health. The current study set out to identify and compare culture isolates of vaginal microflora of human immunodeficiency virus (HIV) positive (HIV+ ) and HIV negative (HIV- ) women at different phases during menstrual cycle from a sub-urban population of Kenya. Seventy four (74) women, 41 HIV+ and 33 HIV- , followed up two consecutive menstrual cycles, had high vaginal swabs taken to prepare Gram stains for six visits and anaerobic cultures for four. All 751 isolates identified by t-DNA polymerase chain reaction (PCR) belong to 51 species. …

Characterizing The Human Vaginal Microbiome Using High-Throughput Sequencing, Jean Megan E. Macklaim

Electronic Thesis and Dissertation Repository

The human vaginal microbiome undoubtedly has a significant role in reproductive health and for protection from infectious organisms. Recent efforts to characterize the bacterial species of the vagina using molecular techniques have uncovered an unexpected diversity. Using high-throughput sequencing I sought to describe the structure and function of the vaginal microbiome under different physiological states including healthy, bacterial vaginosis (BV), post-menopausal vaginal atrophy, and acute vulvovaginal candidiasis (VVC).

Partial 16S rRNA gene sequencing revealed that healthy, asymptomatic women most often have vaginal biotas dominated by Lactobacillus iners or L. crispatus. In contrast, BV is a heterogeneous, highly diversified condition …

Antiseptics And Disinfectants For The Treatment Of Bacterial Vaginosis: A Systematic Review, Hans Verstraelen Verstraelen, Rita Verhelst, Kristien Roelens, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

Background: The study objective was to assess the available data on efficacy and tolerability of antiseptics and disinfectants in treating bacterial vaginosis (BV).

Methods: A systematic search was conducted by consulting PubMed (1966-2010), CINAHL (1982-2010), IPA (1970-2010), and the Cochrane CENTRAL databases. Clinical trials were searched for by the generic names of all antiseptics and disinfectants listed in the Anatomical Therapeutic Chemical (ATC) Classification System under the code D08A. Clinical trials were considered eligible if the efficacy of antiseptics and disinfectants in the treatment of BV was assessed in comparison to placebo or standard antibiotic treatment with metronidazole or clindamycin …

Epidemiologic Features Of Vulvovaginal Candidiasis Among Reproductive-Age Women In India, Sujit D. Rathod, Jeffrey D. Klausner, Karl Krupp, Arthur R. Rhinegold, Purnima Madhivanan

HWCOM Faculty Publications

Background. Vulvovaginal candidiasis is characterized by curd-like vaginal discharge and itching, and is associated with considerable health and economic costs. Materials and Methods. We examined the incidence, prevalence, and risk factors for vulvovaginal candidiasis among a cohort of 898 women in south India. Participants completed three study visits over six months, comprised of a structured interview and a pelvic examination. Results. The positive predictive values for diagnosis of vulvovaginal candidiasis using individual signs or symptoms were low (<19%). We did not find strong evidence for associations between sociodemographic characteristics and the prevalence of vulvovaginal candidiasis. Women clinically diagnosed with bacterial vaginosis had a higher prevalence of vulvovaginal candidiasis (Prevalence 12%, 95% CI 8.2, 15.8) compared to women assessed to be negative for bacterial vaginosis (Prevalence 6.5%, 95% 5.3, 7.6); however, differences in the prevalence of vulvovaginal candidiasis were not observed by the presence or absence of laboratory-confirmed bacterial vaginosis. Conclusions. For correct diagnosis of vulvovaginal candidiasis, laboratory confirmation of infection with Candida is necessary as well as assessment of whether the discharge has been caused by bacterial vaginosis. Studies are needed of women infected with Candida yeast species to determine the risk factors for yeast’s overgrowth.

The Epidemiology Of Bacterial Vaginosis In Relation To Sexual Behaviour, Hans Verstraelen, Rita Verhelst, Mario Vaneechoutte, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

Background: Bacterial vaginosis (BV) has been most consistently linked to sexual behaviour, and the epidemiological profile of BV mirrors that of established sexually transmitted infections (STIs). It remains a matter of debate however whether BV pathogenesis does actually involve sexual transmission of pathogenic microorganisms from men to women. We therefore made a critical appraisal of the literature on BV in relation to sexual behaviour.

Discussion: G. vaginalis carriage and BV occurs rarely with children, but has been observed among adolescent, even sexually non-experienced girls, contradicting that sexual transmission is a necessary prerequisite to disease acquisition. G. vaginalis carriage is enhanced …
