Actividad de fosfolipasas y proteasas en aislamientos de especies de Candida colonizadoras y causantes de vulvovaginitis en mujeres gestantes / Phospholipase and proteinase activities of isolatesof colonizing Candida spp. causing vulvovaginitis in pregnant women

Introducción. Las proteasas y las fosfolipasas son factores de virulencia de Candida spp. que cumplen un papel importante en la invasión de los tejidos. Entre los factores relacionados con el huésped, se encuentran algunos asociados con las características ambientales y otros con la colonización. Objetivo. Determinar la actividad de fosfolipasas y proteasas en aislamientos de especies colonizadoras y patógenas de Candida spp., aisladas de mujeres gestantes de Cartagena de Indias. Materiales y métodos. Se determinó la actividad de fosfolipasas y proteasas en 56 aislamientos mediante degradación del sustrato y cálculo del coeficiente de actividad enzimática. Se compararon las actividades de fosfolipasas y proteasas, entre los aislamientos colonizadores y los patógenos. Resultados. La actividad de la fosfolipasa fue "muy alta" (< 0,69) en 34 aislamientos e, igualmente, la de la proteasa en 14. No hubo diferencias significativas al comparar las actividades de las fosfolipasas y de las de las proteasas, entre los aislamientos colonizadores y los patógenos. Conclusiones. La actividad de las fosfolipasas predominó como factor de virulencia en los aislamientos estudiados. No obstante, no se encontró una diferencia significativa entre los grupos de aislamientos colonizadores y los patógenos, en cuanto a las actividades de fosfolipasas y proteasas.

Introduction. Proteases and phospholipases are virulence factors of Candida spp. that play an important role in tissue invasion. Among the factors related to the host some are associated with environmental characteristics and others with Candida colonization. Objectives. To determine phospholipase and protease activities in colonizing and pathogenic strains, isolated from pregnant women in Cartagena de Indias. Materials and methods. Phospholipase and protease activity was determined in 56 isolates, evaluating substrate degradation and calculating the enzyme activity coefficient. Phospholipase and protease activities were compared between colonizing and pathogenic strains. Results. "Very high" (<0.69) phospholipase and protease activity was found in 34 and 14 isolates, respectively. There was no significant difference when comparing phospholipase and protease activities between colonizing and pathogenic isolates. Conclusions. Phospholipase activity predominated as a virulence factor in the studied strains, but no significant difference was found between colonizing and pathogenic strains for phospholipase and protease activities.

Aspectos da abordagem terapêutica sobre candidíase vulvovaginal / Aspects of the therapeutic approach to vulvovaginal candidiasis / Aspectos del abordaje terapéutico de la candidiasis vulvovaginal

A candidíase vulvovaginal, é uma infecção da vulva e vagina causada por vários tipos de Candida spp. Essa patologia afeta 75% de todas as mulheres pelo menos uma vez durante a vida, ocorrendo com mais frequência durante a idade fértil. A transmissão dessa infeção fúngica ocorre por meio de contato com mucosas e secreções em pele de portadores ou doentes, contato sexual, água contaminada e transmissão vertical. Alguns outros sintomas característicos mais vistos em casos de CVV, são lesões brancas, cremosas e planas, sendo mais intensos no período pré-menstrual, quando a acidez vaginal aumenta. numerosos antifúngicos estão disponíveis no mercado, os quais são encontrados para administração oral na forma de comprimidos ou, para uso tópico, na forma de cremes, loções, comprimidos vaginais, supositórios e tampões revestidos. O objetivo geral do trabalho foi analisar através da revisão de literatura, tratamentos convencionais e alternativos para abordagem terapêutica da Candidíase Vulvovaginal contextuando a mesma, utilizando definições, dados epidemiológicos e sua sintomatologia frente à sociedade. O presente trabalho é uma revisão integrativa, que teve a coleta de dados realizada de março de 2021 a outubro de 2021 nas bases de dados Lilacs, Scielo, Google acadêmico, A busca resultou em 902 artigos, dos quais 14 atenderam ao critério de inclusão. A busca por tratamentos frente a candidíase vulvovaginal tem se mostrado ampla de acordo com os artigos selecionadas. Concluímos que a patologia candidíase vulvovaginal, vem apresentando resistência em algumas abordagens terapêuticas, assim como algumas mulheres não aderem há algum tipo de tratamento, devido à falta de conhecimento sobre a patologia.

Vulvovaginal candidiasis is an infection of the vulva and vagina caused by various types of Candida spp. This condition affects 75% of all women at least once in their lifetime, occurring more frequently during their childbearing years. The transmission of this fungal infection occurs through contact with mucous membranes and secretions on the skin of patients or patients, sexual contact, contaminated water and vertical transmission. Some other characteristic symptoms more seen in cases of VVC are white, creamy and flat lesions, being more intense in the premenstrual period, when the vaginal acidity increases. numerous antifungals are available on the market which are available for oral administration in tablet form or, for topical use, in the form of creams, lotions, vaginal tablets, suppositories and coated tampons. The general objective of the work was to analyze, through a literature review, conventional and alternative treatments for the therapeutic approach of Vulvovaginal Candidiasis in its context, using definitions, epidemiological data and its symptoms in society. The present work is an integrative review, which had data collection carried out from March 2021 to October 2021 in the Lilacs, Scielo, Google academic databases. The search resulted in 902 articles, of which 14 met the inclusion criteria. The search for treatments against vulvovaginal candidiasis has been shown to be wide according to the selected articles. We conclude that the vulvovaginal candidiasis pathology has been showing resistance in some therapeutic approaches, as well as some women do not adhere to any type of treatment, due to lack of knowledge about the pathology.

Introducción: En las micosis, la resistencia a los antifúngicos aumenta debido a los diagnósticos y tratamientos incorrectos. Por tanto, se ha sugerido la vigilancia y el seguimiento de las cepas resistentes para garantizar una terapia adecuada. Objetivo: Determinar las especies de Candida y el perfil de resistencia a fluconazol y voriconazol, que presentan los aislados obtenidos de muestras almacenadas durante los meses diciembre 2017 y marzo 2018 de pacientes provenientes del Laboratorio del Hospital Regional "Miguel Ángel Mariscal Llerena" del departamento de Ayacucho, Perú. Material y Métodos: Estudio descriptivo transversal, en el cual se aislaron 110 cepas de Candida sp almacenadas por un período de cuatro meses, y procesadas por métodos estandarizados y aprobados por el Ministerio de Salud (MINSA) y el Instituto Nacional de Salud (INS) del Perú relacionados con el diagnóstico de agentes etiológicos de micosis humanas y la sensibilidad antifúngica con los métodos estandarizados de Clinical Laboratory Standard Institute (CLSI). Resultados: Se observó C. albicans en 86,4 % de los aislados seguida por C. glabrata con 9,1 %, C. parapsilosis 2,7 % y 0,9 % de C. tropicalis y C. krusei. El 10,5 % de C. albicans fue resistente al fluconazol y voriconazol con CMI ≥ 128 μg/mL y ≥ 16 μg/mL respectivamente, mientras que 20 % de C. glabrata mostró sensibilidad dosis dependiente y 10 % de resistencia al fluconazol. Conclusiones: Existe una gran variedad de especies de Candida, siendo la C. albicans la más común, seguida por C. glabrata, con un mayor porcentaje de aislamiento en comparación con otras especies. Se puede observar que estas especies poseen grados de vulnerabilidad considerables a la aplicación de fármacos como el fluconazol y voriconazo(AU)

Introduction: In mycoses, resistance to antifungals increases due to incorrect diagnosis and treatment. Therefore, surveillance and monitoring of resistant strains has been suggested to ensure adequate therapy. Objective: To determine the Candida species and the resistance profile to fluconazole and voriconazole presented by the isolates obtained from samples stored during the months of December 2017 and March 2018 from patients coming from the Laboratory of the Regional Hospital "Miguel Ángel Mariscal Llerena" in the department of Ayacucho, Peru. Material and Methods: Cross-sectional descriptive study in which 110 strains of Candida sp were isolated and stored for a period of four (04) months, and processed by standardized methods approved by the Ministry of Health (MINSA) and the National Institute of Health (INS) of Peru related to the diagnosis of etiological agents of human mycosis and antifungal sensitivity with the standardized methods of the Clinical Laboratory Standard Institute (CLSI). Results: C. albicans was observed in 86,4 % of isolates, followed by C. glabrata (9,1 %), C. parapsilosis (2,7 %), and 0,9 % of C. tropicalis and C. krusei; 10,5 % of C. albicans was resistant to fluconazole and voriconazole with MIC ≥ 128 μg/mL and ≥ 16 μg/mL respectively, while 20 % of C. glabrata showed dose dependent sensitivity and 10 % resistance to fluconazole. Conclusions: There is a wide variety of Candida species, with C. albicans being the most common, followed by C. glabrata, with a higher percentage of isolation compared to other species. It can be seen that these species have considerable degrees of vulnerability to the application of drugs such as fluconazole and voriconazole(AU)

Analysis of resistance and sensitivity of 1 200 strains of vulvovaginal candidiasis in China to five common antifungal drugs / 中华妇产科杂志

Objective:To test the antibiotic susceptibility of vulvovaginal candidiasis pathogenic strains to 5 antifungal drugs commonly used in clinic.Methods:A total of 1 200 vulvovaginal candida patients from 23 gynecological and family planning outpatient departments in China were enrolled. Their vaginal secretions were collected for candida strain isolation and species identification. According to Clinical and Laboratory Standards Institute (CLSI) M27-S3, the sensitivity of 1 200 strains to clotrimazole, fluconazole, miconazole, itraconazole and nystatin was tested.Results:(1) The sensitivity and resistance of 1 200 vulvovaginal candidiasis pathogens to 5 antifungal drugs were statistically different ( χ2=3 513.201, P<0.01). (2) All strains had higher sensitivity to nystatin [99.92% (1 199/1 200)], followed by miconazole [92.25% (1 107/1 200)] and clotrimazole [87.17% (1 046/1 200)]. All strains had higher resistance to fluconazole [69.17% (830/1 200)], while itraconazole was 50.83% (610/1 200). (3) There was no significant difference between candida albicans and non-candida albicans in drug sensitivity to nystatin ( P=0.315) and miconazole ( P=0.425). (4) Candida albicans and non-candida albicans showed different sensitivity to clotrimazole, fluconazole and itraconazole, respectively. Compared with non-candida albicans, candida albicans showed higher sensitivity to clotrimazole [susceptibility rate: 73.01% (165/226) vs 90.45% (881/974); P<0.001] and higher resistance to fluconazole [resistance rate: 50.88% (115/226) vs 73.41% (715/974); P<0.001]. Although the drug sensitivity of itraconazole was not high, the susceptibility rate of candida albicans to itraconazole was slightly higher than that of non-candida albicans [37.68% (367/974) vs 23.89% (54/226)], and the drug resistance rate was lower [49.28% (480/974) vs 57.52% (130/226)]. Conclusions:The sensitivity of 1 200 strains of candida to 5 antifungal drugs is significantly different, the sensitivity rate of nystatin, miconazole and clotrimazole are higher, but the resistance rate of fluconazole and itraconazole are higher. The sensitivity of candida albicans and non-candida albicans to the same drug is also significantly different. It is suggested that in clinical diagnosis and treatment, we should pay attention to the identification of candida and drug sensitivity test, so as to select antifungal drugs rationally.

Factores de riesgo asociados a infección vaginal en mujeres embarazadas / Risk factors associated to vaginal infections in pregnant women / Fatores de risco associados à infecção vaginal em gestantes

RESUMEN La infección vaginal constituye una de las complicaciones médicas más frecuentes asociadas al embarazo. Se realizó un estudio epidemiológico, observacional, analítico, longitudinal de casos y controles con mujeres embarazadas atendidas en el Policlínico Jimmy Hirzel, Bayamo, Granma, período junio 2016 - diciembre 2017, con el objetivo de identificar factores de riesgo hipotéticamente relacionados con la aparición de infección vaginal. Los datos se obtuvieron a partir de una encuesta aplicada a las pacientes y su historia clínica, previo consentimiento informado. Se aplicó modelo de riesgo proporcional de Cox para análisis univariado y multivariado, y el Chi cuadrado, con una confiabilidad del 95% y una probabilidad menor de 0.05. La historia previa de infección de transmisión sexual (OR 2,25), más de tres gestaciones (OR 3,20), los abortos previos (9,88) y el no empleo de preservativos en las relaciones sexuales (OR 5, 35) se constituyeron en los antecedentes gineco-obstétricos relacionados con la aparición de infección vaginal en mujeres embarazadas. El inicio precoz de la vida sexual (OR 2, 25) se constituyó en un factor demográfico y de conducta sexual relacionado con la aparición de infección vaginal en mujeres embarazadas. Haber recibido algún tipo de tratamiento vaginal previo al estudio (OR 1,26), constituyó un factor de riesgo relacionado con los procedimientos externos, aunque no de forma significativa. La presencia de infección de vías urinarias y de diabetes mellitus se constituyeron en factores de riesgo relacionados con la aparición de infección vaginal en mujeres embarazadas.

ABSTRACT Vaginal infection is one of the most frequent medical complications associated with pregnancy. An epidemiological, observational, analytical, longitudinal study of cases and controls was carried out with pregnant women attended at the Jimmy Hirzel Polyclinic, Bayamo, Granma, June 2016 - December 2017, with the objective of identifying risk factors hypothetically related to the appearance of vaginal infection. The data was obtained from a survey applied to patients and their clinical history, with prior informed consent. Cox proportional risk model was applied for univariate and multivariate analysis, and Chi square, with a 95% reliability and a probability lower than 0.05. The previous history of sexually transmitted infection (OR 2.25), more than three pregnancies (OR 3.20), previous abortions (9.88) and the non-use of condoms in sexual relations (OR 5, 35) were constituted in the gynecological-obstetric history related to the appearance of vaginal infection in pregnant women. The early onset of sexual life (OR 2, 25) became a demographic and sexual behavior factor related to the appearance of vaginal infection in pregnant women. Having received some type of vaginal treatment prior to the study (OR 1.26), constituted a risk factor related to external procedures, although not in a significant way. The presence of urinary tract infection and diabetes mellitus constituted risk factors related to the appearance of vaginal infection in pregnant women.

Vaginal colonization and vulvovaginitis by Candida species in pregnant women from Northern of Colombia / Vulvovaginitis y colonización vaginal por especies de Candida en gestantes del norte de Colombia

Objective: identify the vaginal colonizing Candida species and VVC species, predisposing factors and susceptibility against fluconazole in pregnant women attending gynecological outpatient of a maternal clinic in Cartagena (Colombia). Vulvovaginal candidiasis (VVC) is a common infection that affects a large proportion of women of childbearing age. It is estimated that about 75% of healthy women have had at least one episode of VVC in her life. Vaginal colonization by Candida spp. can vary from 10 to 17% and this is increased by 35% during pregnancy. The epidemiological behavior of Candida in VVC tends to be variable and this will depend on the level of vaginal estrogens, conditions of immunosuppression or chronicity of the process. Materials and Methods: the laboratory study included the direct examination of vaginal swabs, by fresh and differential staining of smears and cultures. The isolated species were identified by phenotypic tests and by multiplex PCR and CLSI M27-A3 microdilution method was used to evaluate susceptibility to fluconazole. Results: the frequent clinical diagnosis of bacterial vaginosis, did not correspond with the laboratory diagnosis in which predominated the intermediate biota. The results showed Candida albicans as the most common isolated species, followed by Candida tropicalis and Candida krusei.Candida colonization occurred in 71.4% and 28.6% of the population was diagnosed with vaginal candidiasis. All isolates were susceptible to fluconazole. Conclusion:The most common factors for colonization were related to clothing and for vaginal candidiasis to the use of vaginal lubricants..(AU)

Objetivo: identificar las especies colonizantes y asocidadas a CVV, factores predisponentes y sensibilidad a fluconazol en gestantes que asistieron a la consulta externa ginecológica de una clínica materna de Cartagena (Colombia). La candidiasis vulvovaginal (CVV) es una infección común que afecta una gran proporción de mujeres en edad fértil. Se estima que un 75% de las mujeres sanas han tenido al menos un episodio de CVV en su vida. La colonización vaginal por Candida spp. varía del 10 al 17% y esta alcanza un 35% durante el embarazo. El comportamiento epidemiológico del género Candida en la VVC es variable y dependerá del nivel de estrógenos de la vagina, inmunosupresión o cronicidad del proceso. Materiales y métodos: el estudio de laboratorio comprendió, examen directo de exudados vaginales, mediante fresco y tinciones diferenciales. Los aislamientos se identificaron por pruebas fenotípicas y PCR múltiple y se utilizó el método M27-A3 del CLSI por microdilución para la evaluación de la sensibilidad a fluconazol. Resultados: el diagnóstico médico frecuente de vaginosis bacteriana no correspondió con el de laboratorio en el que predominó la biota intermedia. Los resultados revelaron a Candida albicans como la especie más frecuente, seguida por Candida tropicalis y Candida krusei. La colonización por Candida fue del 71,4% y la candidiasis vaginal del 28,6%. Los aislamientos resultaron sensibles a fluconazol. Conclusión: los factores más frecuentes para colonización se relacionaron con la ropa y para candidiasis vaginal, con el uso de lubricantes vaginales..(AU)

The value of microecological testing on evaluation of the treatment effect of simple vulvovaginal candidiasis / 中华检验医学杂志

Objective To analyze the value of vaginal microecological detection in evaluating therapeutic effect of simple vulvovaginal candidiasis(VVC), and explore microecological factors which can affect the cure rate of simple VVC.Methods 75 patients with simple VVC in Tianjin Medical University General Hospital from January 2016 to June 2017 were enrolled.Vaginal secretion was collected and applied for vaginal microecological detection.The patients were treated with clotrimazole based monotherapy later. The relationship between vaginal microecological characters and therapeutic effects was analyzed.Results PH values,leukocyte counts,flora density,flora diversity,small bacilli and cocci counts had no influence on therapeutic effects(P>0.05).The cure rate of patients with lactobacillary gradesⅠ-Ⅱa was higher than that with lactobacillary gradesⅡb-Ⅲ(83.33% vs 53.33%,P=0.033), while lower with lactobacilli≤22.8/hpf than that with lactobacilli >22.8/hpf(59.26% vs 87.50%,P=0.007), which indicate that lactobacilli counts was the main factor that affects therapeutic effects.Conclusions Vaginal microecological detection plays an important role in predicting the therapeutic effect of simple VVC.For the patients with lower lactobacillus counts,the follow-up after treatment should be strengthened.(Chin J Lab Med,2018, 41:292-295)

Attach importance to another form of the vaginal microecological balance disorder / 中华检验医学杂志

Cytolytic vaginosis(CV)is a set of clinical syndrome, which is caused by excessive growth of lactobacillus and imbalance of vaginal microecology.The clinical features of CV were often similar to vulvovaginal candidasis,and they were easily misdiagnosed CV is not uncommon clinically.Therefore,in order to diagnose CV rapidly and accurately,vaginal microecology should be evaluated by certain laboratory examinations, such as direct wet mount combined with smear staining.Which can avoid misdiagnosis and improve the efficiency of diagnosis and treatment.(Chin J Lab Med,2018,41:254-255)

Detección de Candida glabrata en mujeres mexicanas sanas y con candidiasis vulvovaginal recurrente / Candida glabrata detection in healthy Mexican women with recurrent vulvovaginal candidiasis

Resumen OBJETIVO: determinar, mediante reacción en cadena de la polimerasa (PCR), si C. albicans y C. glabrata son causantes de las recurrencias de candidiasis vulvovaginal y si suelen colonizar la vagina de mujeres mexicanas asintomáticas en edad reproductiva. MATERIALES Y MÉTODOS: estudio analítico, transversal, prospectivo, experimental, de casos y controles, efectuado en mujeres de 18 a 45 años de edad, atendidas en el servicio de Ginecología del Centro Médico ABC de la Ciudad de México y el Cinvestav del Instituto Politécnico Nacional. Identificar C. albicans y C. glabrata en muestras vaginales por medio de reacción en cadena de la polimerasa con iniciadores específicos para cada especie. RESULTADOS: se estudiaron 93 pacientes: 46 casos y 47 controles. En los casos se encontraron: 2.17% con C. albicans, 80.4% con C. glabrata y 17.3% con coinfección por ambas especies. En los controles se encontraron: 61.7% con C. albicans, 4.2% con C. glabrata, 19.1% con coinfección por ambas especies y 14.8% con ausencia de Candida spp. CONCLUSIONES: el agente causal de la mayor parte de las candidiasis vulvovaginales recurrentes es C. glabrata. La colonización por esta especie y por C. albicans es común y no provoca síntoma alguno, por lo que para su identificación es importante utilizar métodos de diagnóstico como la reacción en cadena de la polimerasa.

Abstract BACKGROUND: 75% of women are affected with vulvovaginal candidiasis and 10% of them will have at least 4 episodes during one year. The most common etiological agents are C. albicans and C. glabrata, which is usually the responsible of the recurrent cases when the patients have received inadequate treatment. Up to 55% of asymptomatic women can have different species of Candida spp. as vaginal commensals, but there are no recent studies that identify this yeast through molecular techniques in healthy women and with history of vulvovaginal candidiasis. OBJECTIVE: Determine using polymerase chain reaction if C. albicans and C. glabrata are responsible of recurrent vulvovaginal candidiasis and if they usually colonize Mexican asymptomatic women in reproductive age. MATERIAL AND METHODS: An analytical, transversal, prospective, experimental, case control study was carried out in women age 18 to 45 in the Gynecology Service of ABC Medical Centre of México City and IPN Cinvestav. C. albicans and C. glabrata were identified in vaginal samples using polymerase chain reaction with specific primers for each specie. RESULTS: A total of 93 patients were studied, 46 cases and 47 controls. 2.17% of the case patients were positive C. albicans, 80.43% for C. glabrata, and 17.39% for both species. 61.70% of the control patients were positive for C. albicans, 4.20% for C. glabrata, 19.14% for both species, and 14.89% were negative for Candida. CONCLUSIONS: The main etiological agent of recurrent vulvovaginal candidiasis is C. glabrata. The vaginal colonization of this specie and C. albicans is common and causes no symptoms, thus, it is important to use diagnostic tools such as polymerase chain reaction to identify them. It is relevant to investigate the factors that help this yeast to cause a symptomatic infection and stop being just a vaginal commensal.

Expression of retinoic acid-related orphan receptors and interleukin-17 in mice with vaginal candidiasis / 中华皮肤科杂志

Objective To investigate the role of T helper 17 cells/interleukin?17(Th17/IL?17) axis in the occurrence of vaginal candidiasis in mice. Methods A total of 120 female BALB/c mice were randomly and equally divided into Ei, En, Ci and Cn groups. Three days before vaginal inoculation, estrogen (Ei and En)groups and control(Ci and Cn)groups received subcutaneous injection of 0.05 mg estradiol and 0.1 ml sterilized soybean oil at the hind legs, respectively, and then the hormone treatment continued every other day until the end of experiment. Infected(Ei and Ci)groups and noninfected(En and Cn) groups were inoculated intravaginally with 10μl(5 × 104 conidia)of Candida albicans suspension and 10μl of sterilized phosphate?buffered saline, respectively. Ten mice were randomly selected from each group and sacrificed on day 3, 7 and 14 after inoculation. The intact vagina tissues were resected and then frozen in liquid nitrogen or embedded in paraffin. Real?time fluorescence?based quantitative PCR(qRT?PCR)and immunofluorescent staining were performed to measure mRNA expression and immunofluorescence intensities of retinoic acid?related orphan receptorγt(RORγt), RORα and IL?17, respectively. Western blot analysis was conducted to determine protein expression of RORγt and IL?17. Results Laser scanning confocal microscopy showed that RORγt, RORα and IL?17 immunofluorescence was mainly located at inflammatory cells of the lamina propria and blood vessels in En and Cn groups, at mucosal epithelium, adherent hyphae, and inflammatory cells of the lamina propria and blood vessels in Ci group, and at mucosal epithelium, vaginal canal and endocytosed hyphae, and inflammatory cells of the lamina propria and blood vessels in Ei group. qRT?PCR and immunofluorescent staining uncovered that mRNA expression and immunofluorescence intensities of RORγt, RORα and IL?17 were significantly higher in En, Ci and Ei groups than in Cn group at the same time points(all P0.05). Moreover, RORγt and IL?17 protein expression in Ci and Ei groups was obviously up?regulated on day 7 after inoculation (RORγt: F = 13.137, P < 0.001; IL?17: F = 11.182, P < 0.001), but was not increased further on day 14. Conclusion Vaginal candida infection can up?regulate the expression of RORγt, RORα and IL?17, suggesting that Th17/IL?17 axis may be involved in the occurrence of vaginal candidiasis in BALB/c mice.

Probiotics in the Prevention and Treatment of Postmenopausal Vaginal Infections: Review Article

Bacterial vaginosis (BV) and complicated vulvovaginal candidiasis (VVC) are frequently occurring vaginal infections in postmenopausal women, caused by an imbalance in vaginal microflora. Postmenopausal women suffer from decreased ovarian hormones estrogen and progesterone. A normal, healthy vaginal microflora mainly comprises Lactobacillus species (spp.), which act beneficially as a bacterial barrier in the vagina, interfering with uropathogens. During premenopausal period, estrogen promotes vaginal colonization by lactobacilli that metabolizing glycogen and producing lactic acid, and maintains intravaginal health by lowering the intravaginal pH level. A lower vaginal pH inhibits uropathogen growth, preventing vaginal infections. Decreased estrogen secretion in postmenopausal women depletes lactobacilli and increases intravaginal pH, resulting in increased vaginal colonization by harmful microorganisms (e.g., Enterobacter, Escherichia coli, Candida, and Gardnerella). Probiotics positively effects on vaginal microflora composition by promoting the proliferation of beneficial microorganisms, alters the intravaginal microbiota composition, prevents vaginal infections in postmenopausal. Probiotics also reduce the symptoms of vaginal infections (e.g., vaginal discharge, odor, etc.), and are thus helpful for the treatment and prevention of BV and VVC. In this review article, we provide information on the intravaginal mechanism of postmenopausal vaginal infections, and describes the effectiveness of probiotics in the treatment and prevention of BV and VVC.
