RESUMO

Vulvovaginal candidiasis (VVC) is the most common cause of vaginal discharge among women. The present study aimed to investigate the synergistic anticandidal effect of lactobacillus cultures supplemented with plant extracts. Among 600 isolates of lactic acid bacteria, 41 isolates exhibited inhibitory activity against Candida albicans ATCC10231. Six out of 41 cell-free supernatants demonstrated the most potent antibacterial and anticandidal activities. They also inhibited the clinical isolates of C. albicans, causing VVC and non-C. albicans. The synergistic effect between Lactobacillus crispatus 84/7 and Limosilactobacillus reuteri 89/4 was demonstrated by the lowest fractional inhibitory concentration index (FICI = 0.5). The synbiotic culture of bacterial combination, cultured with Jerusalem artichoke (H. tuberosus) extract, also exhibited the strongest inhibition against the tested C. albicans. Biofilm formation decreased after 12 h of incubation in the selected cell-free supernatants of this synbiotic culture. The anticandidal activity of crude extracts was lost after treatment with proteinase K and trypsin but not with heating conditions, suggesting that it may be a heat-stable substance. In conclusion, the combination of L. crispatus 84/7 and L. reuteri 89/4 with H. tuberosus may be a promising candidate for inhibiting Candida infection and biofilm formation, with the potential use as ingredients in vaginal biotherapeutic products.

RESUMO

BACKGROUND: Abnormal vaginal discharge is a common complaint among women of reproductive age, affecting about one- third of all women. In resource-limited settings where access to laboratory services is limited, treatment is usually syndromic. This approach may result in ineffective treatment, with high recurrence rates and a potential of developing antibiotic resistance. This study aimed to determine the bacterial isolates and antibiotic susceptibility among women with an abnormal vaginal discharge attending the gynecology clinic at a tertiary hospital in Southwestern Uganda. METHODS: We conducted a hospital based cross-sectional study among 361 women aged 15-49 years, presenting with abnormal vaginal discharge at the gynecology clinic of Mbarara Regional Referral Hospital from December 2020 to June 2021. Demographic characteristics were collected using a structured questionnaire. We collected cervical and vaginal sterile swabs and subjected them to wet preparation and gram stain. The specimens were cultured for bacterial isolates. Susceptibility testing was performed on samples with bacterial isolates using the Kirby-Bauer disc diffusion method, on the commonly prescribed antibiotics in this setting. We summarized and described the bacterial isolates and antibiotic susceptibility patterns as frequencies and percentages. RESULTS: We enrolled 361 women with abnormal vaginal discharge. Bacteria were isolated in 29.6% (107/361) of the women, and the commonest isolates included; Staphylococcus aureus 48.6% (52/107), Klebsiella pneumoniae 29.9% (32/107) and Enterococcus faecalis 15% (16/107). Yeast cells were found in 17.7% (64/361) of the women with abnormal vaginal discharge. Cefuroxime (90.7%) and Ciprofloxacin (81.3%) had a high level of sensitivity while high levels of resistance were observed for Doxycycline (86.0%) and Azithromycin (67.0%). CONCLUSION: The common bacterial isolates were Staphylococcus aureus, Klebsiella pneumoniae and Enterococcus faecalis. The isolated bacteria were most sensitive to Cefuroxime and Ciprofloxacin but resistant to Doxycycline and Azithromycin. There is need for routine culture and susceptibility testing of women with abnormal vaginal discharge so as to guide treatment, minimize inappropriate antibiotic use and consequently reduce antibiotic resistance.

RESUMO

PURPOSE: Nonspecific vaginitis is a distinct clinical entity with particular microscopic and immunologic features. There is currently no standard of care for women with nonspecific vaginitis. The aim of our study was to assess the change in vaginal symptoms score after 3 months of treatment with an intravaginal medical device in participants with abnormal vaginal discharge and specific signs and symptoms. As secondary objectives, the study analyzed other clinical and microscopic features, such as vaginal discharge aspect, change in vaginal pH, change in vaginal microbiome, and vaginal inflammation. METHODS: The study population included 47 participants with symptomatic vulvovaginitis, distinct from candidiasis, trichomoniasis, or bacterial vaginosis. The study design included 2 research sites from Romania. The treatment protocol consisted of 1 ovule per day inserted intravaginally during 15 consecutive days. The total study duration was 3 months. FINDINGS: The intravaginal medical device had a positive impact on the vaginal symptoms score for 72.34% of the study participants. Topical administration of the ovules balanced vaginal pH values and significantly reduced signs of inflammation between study visits. IMPLICATIONS: This intravaginal medical device had curative effects that support its use as a stand-alone treatment in women with nonspecific vaginitis. A second clinical investigation is ongoing to evaluate the clinical efficacy of the device in postoperative care of cervical and vaginal wounds traumatic or secondary to surgical interventions. CLINICALTRIALS: gov identifier: NCT04735705.

RESUMO

BACKGROUND: Pathological vaginal discharge is a common complaint of women in reproductive age worldwide caused by various agents. The prevalence and etiologic agents vary depending on the population studied. Management of vaginal discharge in low-income countries, typically depend on the syndromic approach, which limits understanding the specific causative agents. We determined the proportion of bacterial vaginosis, candidiasis, and trichomoniasis among women with vaginal discharge at a regional referral hospital in Dar es Salaam, Tanzania. METHODS: We conducted a cross-sectional study between June and August of 2017 among nonpregnant women at Amana Regional Referral Hospital. Experienced staff performed physical examination to establish a clinical diagnosis, and collection of the high vaginal swab for microscopic examination. Descriptive statistics were performed to assess the characteristics of study participants and the proportion of vaginal infections. RESULTS: A total of 196 samples were collected, of all, 128 (65.3%) had either bacterial vaginosis, candidiasis, or trichomoniasis. Bacterial vaginosis was the leading infection at 33.2%, followed by candidiasis (19.4%) and trichomoniasis (13.3%). Laboratory confirmed vaginal infection were generally found more in age below 25, unmarried, and those employed or petty business. CONCLUSION: The proportion of bacterial vaginosis in women with vaginal discharge was relatively higher than others, and the presence of vaginal infection relate to socio-demographic characteristics. Further advanced studies are needed to understand the potential role of aetiologic agents in causing vaginal infections.

RESUMO

Abnormal vaginal discharge may be caused by bacterial vaginosis, vulvovaginal candidiasis, trichomoniasis and/or aerobic vaginitis. For the development of a diagnostic algorithm, tree-based classification analysis was performed on symptoms, signs and bedside test results of 56 patients, and laboratory tests (culture, Nugent score, qPCRs) were compared. Amplicon sequencing of the 16S rRNA gene was used as reference test for bacterial vaginosis and aerobic vaginitis, culture for vulvovaginal candidiasis and qPCR for trichomoniasis. For bacterial vaginosis, the best diagnostic algorithm was to screen at the bedside with a pH and odour test and if positive, to confirm by qPCR (sensitivity 94%; specificity 97%) rather than Nugent score (sensitivity of 59%; specificity 97%; P = 0.031). The analysis for the other infections was less conclusive due to the low number of patients with these infections. For bacterial vaginosis, the developed algorithm is sensitive, specific, and reduces the need for laboratory tests in 50% of the patients.

RESUMO

BACKGROUND: Vaginal candidiasis is frequent in women of reproductive age. Accurate identification Candida provides helpful information for successful therapy and epidemiology study; however, there are very limited data from the Vietnam have been reported. This study was performed to determine the prevalence, species distribution of yeast causing vaginal discharge and antifungal susceptibility patterns of Candida albicans among symptomatic non-pregnant women of reproductive age. METHODS: Vaginal discharge samples were collected from 462 women of reproductive age in Hanoi, Vietnam between Sep 2019 and Oct 2020. Vaginal swabs from these patients were examined by direct microscopic examination (10% KOH). CHROMagar™ Candida medium and Sabouraud dextrose agar supplemented with chloramphenicol (0.5 g/l) were used to isolate yeast, and species identification was performed using morphological tests and molecular tools (PCR and sequencing). Antifungal susceptibility testing was determined according to the Clinical and Laboratory Standards Institute guidelines (M27-A3 and M27-S4). RESULTS: The prevalence of vaginal yeast colonization in non-pregnant women was 51.3% of 462 participants. Nine different yeast species were identified. Among these isolates, C. albicans (51.37%) was the most frequent, followed by C. parapsilosis (25.88%), C. glabrata (11.37%), C. tropicalis (4.31%), C. krusei (3.92%), C. africana (1.57%), Saccharomyces cerevisiae (0.78%), C. nivariensis (1 isolates, 0.39%), and C. lusitaniae (1 isolates, 0.39%), respectively. Among C. albicans, all 46 isolates were 100% susceptible to micafungin, caspofungin, and miconazole. The susceptibility rates to amphotericine B, 5-flucytosine, fluconazole, itraconazole and voriconazole were 95.65, 91.30, 91.30, 82.61 and 86.95%, respectively. CONCLUSIONS: The prevalence of VVC among symptomatic non-pregnant women of reproductive age in Vietnam was higher than many parts of the world. The high frequency of non-albicans Candida species, which were often more resistant to antifungal agents, was a notable feature. Resistance rates of vaginal C. albicans isolates to antifungal agents was low. Our findings suggest that continued surveillance of changes in species distribution and susceptibility to antifungals should be routinely screened and treated.

RESUMO

Vulvovaginitis is a common problem in the GP's practice. Causes are bacterial vaginosis (BV), Candida infection and sexually transmitted infections (STIs). Only if empirical treatment fails, a vaginal swab is sent in for culture and BV detection. However, without culture essential, bacterial pathogens may escape diagnosis. Many molecular BV assays have recently appeared on the marketplace, all quite differing in price and targets. However, for years, the Nugent score has been the gold standard for BV detection. We analysed retrospectively 10 years of microbiology results of vulvovaginal swabs, focusing on less frequently reported bacterial pathogens, and assessed the characteristics of BV diagnostics. Vulvovaginal swabs sent in between 2010 and 2020 from > 11,000 GP patients with vulvovaginitis associated symptoms, but negative STI tests, were analysed. First cultures and repeat cultures after at least 6 months were included in four age groups: < 12, 12-17, 18-51 and > 51 years. Candida species and BV were most frequently found, with the highest prevalence in premenopausal women. Haemophilus influenzae, beta-haemolytic streptococci, Streptococcus pneumoniae and Staphylococcus aureus were isolated in 5.6% of all cultures, with the highest percentages in children and postmenopausal women. If empirical treatment of vulvovaginitis fails, bacterial culture should be performed to detect all potentially pathogenic microorganisms to obtain a higher rate of successful diagnosis and treatment, avoiding unnecessary antimicrobial use and costs. For BV detection, molecular testing may seem attractive, but Nugent scoring still remains the low-cost gold standard. We recommend incorporating the above in the appropriate guidelines.

RESUMO

Bacterial vaginosis (BV) is perceived as a condition of disrupted vaginal microbiota, but remains of unknown aetiology. In this study, vaginal microbiota composition was determined in twenty-one women with BV, before and after treatment with metronidazole or clindamycin. Microbiota composition varied greatly between women and defining a (un)healthy vaginal microbiota state remains elusive, challenging BV diagnosis and treatment. While relative abundance of Lactobacillus increased after antibiotic treatment in two-third of women, its abundance was not associated with treatment outcome. Instead, remaining complaints of abnormal vaginal discharge were more common after metronidazole treatment and associated with increased relative abundance of Ureaplasma.

RESUMO

The bacterium Coxiella burnetii has been associated with reproduction disorders in dairy cattle. A cross-sectional study was conducted in Québec, Canada, to estimate the prevalence of C. burnetii in dairy cows from C. burnetii RT-PCR-positive and/or ELISA-positive herds. As a secondary objective, the associations between C. burnetii-positivity and three reproductive outcomes (purulent vaginal discharge, cytological endometritis, and success at first service) were assessed. A total of 202 post-parturient dairy cows from nine herds were sampled at 35 ± 7 days in milk. Vaginal mucus and composite milk were collected from each cow and screened for the presence of C. burnetii by real-time PCR (RT-PCR) and ELISA, respectively. Purulent vaginal discharge and cytological endometritis were evaluated using a Metricheck device and a modified cytobrush, respectively. The first insemination postpartum was done following an ovulation synchronization protocol around 70 days in milk, and success at first service was recorded. Multilevel logistic regressions adjusted for parity were used to model purulent vaginal discharge, cytological endometritis and success at first service according to C. burnetii cow status. All 202 RT-PCR-assayed vaginal samples were C. burnetii-negative. A positive result for anti-C. burnetii antibodies detection in composite milk was obtained in 25/202 samples and a doubtful result in 4/202 samples. After adjustment for sampling weights, the 202 ELISA-assayed composite milk samples gave an estimated overall prevalence of C. burnetii positive cows of 12.9 % (CI = 6.1-19.6 %) and of doubtful cows of 1.4 % (CI = 0.0-3.3 %). The proportion of ELISA-positive cows was lower in first parity (0%) compared to second (17.1 %) or third parity cows (20.0 %). The associations between ELISA positivity and reproductive outcomes were not statistically significant, perhaps due to the limited sample size, but could be used as pilot estimate for large-scale studies investigating the impact of C. burnetii infection on reproduction disorders in dairy cattle.

RESUMO

Sexually transmitted infections (STIs) disproportionately affect young people, with more than half of the infections occurring in youth aged 15 to 25 years. (1)(2) This review, the second in a 2-part series on STIs, focuses on infections that may cause abnormal vaginal or penile discharge, including trichomonas, chlamydia, gonorrhea, and pelvic inflammatory disease (PID). Most infected persons, however, are asymptomatic. Nucleic acid amplification tests are the most sensitive and specific for the detection of chlamydia, gonorrhea, and trichomoniasis, and they can be performed on provider- or patient-collected swabs. Providers should have a low threshold for diagnosing and treating PID because untreated PID can have serious long-term complications for young women. Indications for hospitalization for PID include the presence of a tubo-ovarian abscess, severe illness with systemic symptoms, pregnancy, human immunodeficiency virus infection, and failure to respond to outpatient oral treatment (within 48-72 hours) or inability to tolerate the oral treatment.

RESUMO

The concept of vaginal dysbiosis was for long considered synonymous with bacterial vaginosis (BV), which is characterized by a homogenous non-inflammatory vaginal discharge. The inflammatory variant of vaginal dysbiosis, called aerobic vaginitis (AV), has remained unknown to a large part of the global dermatology and venereology community, gynaecologists and reproductive tract infection specialists with consequential under diagnosis. AV significantly differs from BV, in clinical presentation, diagnostic criteria and management. The deleterious impact of untreated AV on pregnancy merits discussion. Understanding AV is also crucial for better comprehension of desquamative inflammatory vaginitis (DIV), the most severe form of the same entity. We review the condition's epidemiology, risk factors and suspected aetiology, symptoms and signs, and the latest evidence-backed approach to diagnosis and treatment. The ideal diagnostic approach and treatment for AV/DIV are yet to be established. The currently recommended diagnostic approach for AV/DIV merits an overhaul by incorporating changes to render it feasible for resource-constraint countries. The diagnostic criteria lack a uniform applicability in different physiological groups of women and cannot be used in postpartum or postmenopausal states at the same cut-off levels. Similarly, treatment guidelines merit a relook, and customization, given the equivocality of options suggested by different investigators.

RESUMO

A Gram-stain-positive anaerobic rod-shaped bacterium, designated strain Marseille-P3275T, was isolated using culturomics from the vaginal discharge of healthy French woman. Marseille-P3275T was non-motile and did not form spores. Cells had neither catalase nor oxidase activity. The major fatty acids were C16 : 0 (29 %), C18:1ω9 (18 %), and iso-C15 : 0 (17 %). The genomic DNA G+C content was 50.64 mol%. The phylogenetic analysis based on 16S rRNA gene sequence indicated that Marseille-P3275T was related to members of the family Propionibacteriaceae (between 90.32-92.92 % sequence similarity) with formation of a clade with the monospecific genus Propionimicrobium (type species Propionimicrobium lymphophilum). On the basis of these phylogenetic and phenotypic differences, Marseille-P3275T was classified in a novel genus, Vaginimicrobium, as Vaginimicrobium propionicum gen. nov., sp. nov. The type strain is Marseille-P3275T (=CSUR P3275T=CECT 9677T).

RESUMO

BACKGROUND: Sow endometritis is a common disease in pig breeding farms after artificial insemination, which leads to gray-green vaginal secretions and decreased conception rates. It is important to perform an etiologic diagnosis for effective treatments and control of diseases. The aim of this study was to carry out a pathogenic detection in five specimens of vaginal secretions collected from sick pigs with endometritis, implement identification of the pathogens by phenotypic detection and 16 s rDNA sequence and phylogeny analysis, and determinate antibiotic susceptibility of the isolates. RESULTS: A Streptococcus strain was isolated and identified from all of the five specimens. The isolate was positive for Voges-Proskauer (V-P) and for the hydrolysis of arginine, esculin and myelin-associated glycoprotein (MAG). Acid formation was observed for sorbitol, mushroom sugar, sucrose, and glucose. The 16S rDNA sequence of the isolate possessed 99.93% similarity to that of Streptococcus porcinus. The phylogenetic analysis of 16S rDNA sequence showed that the isolate belonged to the same clade as the S. porcinus strains from humans, pigs, and other animals. The isolate exhibited multi-drug resistance to aminoglycosides, quinolones, macrolides and tetracyclines except being sensitive to some ß- lactams such as penicillin G, cephalothin, cefazolin, cephradine and cefuroxime. CONCLUSIONS: A S. porcinus isolate with multi-drug resistance was identified from vaginal secretions of sows with endometritis in one pig breeding farm, which suggests that the sow endometritis was caused by S. porcinus infection during artificial insemination. This study indicates that sensitive antibiotics such as penicillin G or some cephalosporins could be used for treatment of the diseases. In addition, the study hints that bacterial multi-drug resistance is a tough problem for disease treatment in pig farms.

RESUMO

OBJECTIVE: To identify factors associated with testing for and diagnosis of trichomoniasis in pregnancy and to describe patterns of treatment and tests of reinfection or persistence. METHODS: We conducted a retrospective cohort study of women who delivered from July 2016 to June 2018 at one institution. Testing for Trichomonas vaginalis infection was done by wet mount microscopy or by nucleic acid amplification testing for routine prenatal testing or symptomatic visits. Poisson regression was used to identify factors associated with testing for trichomoniasis and testing positive in pregnancy. Treatment and re-testing patterns also were assessed. RESULTS: Among 3,265 pregnant women, 2,489 (76%) were tested for T vaginalis infection. Of the total sample, 1,808 (55%) were tested by wet mount microscopy, 1,661 (51%) by nucleic acid amplification testing, and 980 (30%) by both modalities. The sensitivity for microscopy compared with nucleic acid amplification testing was 26%, with a specificity of 99%. Factors associated with increased likelihood of being tested included younger age (adjusted risk ratio [aRR] 0.99, 95% CI 0.99-1.00) and bacterial vaginosis (aRR 1.17, 95% CI 1.01-1.37). Prevalence of trichomoniasis was 15% among those tested by any modality (wet mount or nucleic acid amplification testing). Risk factors for trichomoniasis included younger age (aRR 0.97, P<.01), being of black race (aRR 2.62, P<.01), abnormal vaginal discharge (aRR 1.45, P<.01), and chlamydia during the current pregnancy (aRR 1.70, P<.01). Women diagnosed by microscopy had a shorter time to treatment compared with those diagnosed by nucleic acid amplification testing. Most (75%) women with positive infections had a test of reinfection; 29% of these were positive. Bacterial vaginosis was associated with decreased risk of a positive test of reinfection. CONCLUSION: Although testing for and treatment of trichomoniasis during pregnancy is not routinely recommended, the high burden of infection among some pregnant women demonstrates a need to further understand patterns of T vaginalis testing and infection. Opportunities exist for improving timely treatment of trichomoniasis and test of reinfection.

RESUMO

BACKGROUND: Vaginal candidiasis is frequent in pregnant women and is associated with sepsis and adverse neonatal outcomes. This study determined the prevalence of candida species in symptomatic pregnant women and evaluated the antifungal susceptibility profile of the isolated Candida strains. It also aimed to explore whether Candida species predicts gestational complications and adverse neonatal outcomes. METHODS: A total of 258 pregnant women with vaginal discharge at 35 to 37 week of gestation participated in this study. Vaginal swabs from these patients were collected at various obstetrics and gynecology clinics in Lebanon for a period of 14 months. Candida isolates were identified at species level and antifungal susceptibility of Candida albicans to fluconazole (FCZ), amphotericin B (AMB), itraconazole (ICZ) and voriconazole (VCZ) was determined by the agar-based E-test method. RESULTS: Among 258 women tested, 100 (39%) were positive for Candida species. C. albicans, C. glabrata and C. krusei were isolated from 42, 41 and 17% of the women, respectively. C. albicans was significantly associated only with gestational diabetes while C. krusei or C. glabrata had significant positive associations with other gestational complications. The antifungal susceptibility tests of C. albicans isolates revealed 97.5, 90, 87.5 and 97.5% susceptibility to AMB, FCZ, ICZ and VCZ, respectively. CONCLUSION: The current study revealed high incidence of both C. albicans and non-C. albicans Candida strains causing vulvovaginitis among pregnant women in Beirut, Lebanon. Candida screening as antenatal follow up is advised to minimize the risk of adverse neonatal outcome or gestational complications.

RESUMO

A preliminary symptom-based screening test would lower the financial burden of sexually transmitted infections (STIs) caused by clinical testing. To develop such a screening method, we should first identify the most specific STI symptoms. We aim to distinguish the specific STI symptom(s) that are most likely to be found in the truly infected individuals. We used data from a population-based survey that was conducted in Iran, in 2014. Using Latent Class Analysis (LCA) in R software, we classified 3049 Iranian women, 18-60 years old, with reference to seven self-reported STI-associated symptoms. Using LCA, we categorized nearly 1% of women as "probably STI-infected". Above 70% of participants reported the "seven symptoms" that are associated with STIs, except for genital ulcer. These symptoms could be used to distinguish healthy participants from infected ones. The "probably healthy" class incorporated about 77% of the participants. Lower abdominal pain and abnormal vaginal discharge were the most frequently reported symptoms of this class. The LCA determined classes along with the WHO syndromic guidelines for STI diagnosis can help physicians to make a more accurate diagnosis. Hence, cost-effectively, only patients who are classified as probably infected need to be referred to medical laboratories for further investigations.

RESUMO

Postpartum endogenous fungal endophthalmitis in otherwise healthy females is extremely rare disease. We report a case of a 25-year-old female patient referred with a history of decreased vision in her right eye 1 month after uncomplicated vaginal delivery. She presented with multifocal chorioretinal infiltrates. The patient showed persistent inflammation in her right eye then after. Systemic workup was unremarkable apart from a history of vaginal discharge during peripartum period. Vaginal swap confirmed the presence of Candida albicans. Culture of the vitreous sample confirmed the growth of C. albicans. The patient was managed with intravitreal amphotericin B in addition to systemic antifungal treatment followed by pars plana vitrectomy. The patient achieved 20/40 vision with quiet eye after 6 months of follow-up.

RESUMO

BACKGROUND: Syphilis prevalence in sub-Saharan Africa appears to be stable or declining but is still the highest globally. Ongoing sentinel surveillance in high-risk populations is necessary to inform management and detect changes in syphilis trends. We assessed serological syphilis markers among persons with sexually transmitted infections in Zimbabwe. METHODS: We studied a predominantly urban, regionally diverse group of women and men presenting with genital ulcer disease (GUD), women with vaginal discharge and men with urethral discharge at clinics in Zimbabwe. Syphilis tests included rapid plasma reagin and the Treponema pallidum hemagglutination assay. RESULTS: Among 436 evaluable study participants, 36 (8.3%) tested positive for both rapid plasma reagin and Treponema pallidum hemagglutination assay: women with GUD: 19.2%, men with GUD: 12.6%, women with vaginal discharge: 5.7% and men with urethral discharge: 1.5% (P < 0.0001). CONCLUSIONS: Syphilis rates in Zimbabwe are high in sentinel populations, especially men and women with GUD.
