ABSTRACT

• The balanced vaginal microbiome is the main factor defending the vaginal environment against infections. Lactobacilli play a key role in this regard, maintaining the vaginal pH within the normal range (3.8 to 4.5). •Hormonal and immune adaptations resulting from pregnancy influence changes in the vaginal microbiome during pregnancy. •An altered vaginal microbiome predisposes to human immunodeficiency virus (HIV) infection. •Bacterial vaginosis is the main clinical expression of an imbalanced vaginal microbiome. •Vulvovaginal candidiasis depends more on the host's conditions than on the etiological agent. •Trichomonas vaginalis is a protozoan transmitted during sexual intercourse. •The use of probiotics is not approved for use in pregnant women.

ABSTRACT

PROBLEM: The association of viruses with infertility remains incompletely evaluated. METHOD OF STUDY: Vaginal secretions from 46 women seeking treatment in the Center for Reproductive Medicine and Infertility at Weill Cornell Medicine were tested for viruses by metagenomic analysis by lab personnel blinded to all clinical data. RESULTS: Torquetenovirus (TTV) was identified in 16 women, alphapapillomavirus in seven women and most were positive for bacteriophages. Twelve of the subjects were fertile and sought to freeze their oocytes for future implantation. These women were all negative for TTV. In contrast, 16 of the 34 women (47.1%) being treated for infertility were TTV-positive (p = .0035). Evaluating the women by cause of infertility, five of nine women (55.6%) whose male partner had inadequate sperm parameters and six of 14 women (42.9%) with defective ovulation were TTV positive (p = .0062 and p = .0171, respectively, vs. the fertile women). Alphapapillomavirus was identified in one (8.3%) fertile woman, five (35.7%) women with ovulation deficiency, and one (11.1%) woman with male factor infertility. These differences were not statistically significant. There were no differences in bacteriophage families or the presence of Lactobacillus phages between fertile or infertile women or between different causes of infertility. There was a negative association between TTV detection and Lactobacillus crispatus dominance in the vaginal microbiota (p = .0184), but no association between TTV detection and the presence of alphapapillomavirus or Candida species. CONCLUSION: Detection of TTV in the vagina might be a biomarker for specific causes of infertility.

ABSTRACT

An elevated pro-inflammatory cytokine response is associated with severe life-threatening symptoms in individuals with Coronavirus Disease-2019 (COVID). The inflammasome is an intracellular structure responsible for generation of interleukin (IL)-1ß and IL-18. NALP3, a product of the CIAS1 gene, is the rate-limiting component for inflammasome activity. We evaluated if a CIAS1 42 base pair length polymorphism (rs74163773) was associated with severe COVID. DNA from 93 individuals with severe COVID, 38 with mild COVID, and 98 controls were analyzed for this polymorphism. The 12 unit repeat allele is associated with the highest inflammasome activity. Five alleles, corresponding to 6, 7, 9, 12 or 13 repeat units, divided into 12 genotypes were identified. The frequency of the 12 unit repeat allele was 45.3% in those with severe disease as opposed to 30.0% in those with mild disease and 26.0% in controls (p < 0.0001, severe vs. controls). In contrast, the 7 unit repeat allele frequency was 30.1% in controls as opposed to 14.0% and 12.5% in those with severe or mild disease, respectively (p ≤ 0.0017). We conclude that individuals positive for the CIAS1 12 allele may be at elevated risk for development of severe COVID due to an increased level of induced pro-inflammatory cytokine production.

ABSTRACT

Suppressive therapy of recurrent genital herpes is a challenge, and melatonin may be an alternative. OBJECTIVE: To evaluate the action of melatonin, acyclovir, or the association of melatonin with acyclovir as a suppressive treatment in women with recurrent genital herpes. DESIGN: The study was prospective, double-blind, and randomized, including 56 patients as follows: (a) The melatonin group received 180 placebo capsules in the 'day' container and 180 melatonin 3 mg capsules in the 'night' container (n = 19); (b) The acyclovir group received 360 capsules of 400 mg acyclovir twice a day (one capsule during the day and another during the night) (n = 15); (c) the melatonin group received 180 placebo capsules in the 'day' container and 180 melatonin 3 mg capsules in the 'night' container (n = 22). The length of treatment was six months. The follow-up after treatment was six months. Patients were evaluated before, during, and after treatment through clinical visits, laboratory tests, and the application of four questionnaires (QSF-36, Beck, Epworth, VAS, and LANNS). RESULTS: No statistically significant difference was observed for the depression and sleepiness questionnaires. However, in the Lanns scale for pain, all groups decreased the mean and median values in time (p = 0.001), without differentiation among the groups (p = 0.188). The recurrence rates of genital herpes within 60 days after treatment were 15.8%, 33.3%, and 36.4% in the melatonin, acyclovir, and association of melatonin with acyclovir groups, respectively. CONCLUSION: Our data suggest that melatonin may be an option for the suppressive treatment of recurrent genital herpes.

ABSTRACT

The microbial composition of the human vagina differs from that of all other mammals, likely as a consequence of the unique composition of vaginal constituents that promote the selective maintenance and proliferation of distinct bacterial species. Similarly, variations between individual healthy women in genetic, environmental, and medical variables also modify the vaginal lumen composition. The direction and magnitude of immune reactions to microorganisms present in the vagina, responses to stress and non-infectious stimuli, coupled with medical and pregnancy history and environmental exposures, can greatly differ between women. Adaptations to both internal and external pressures will determine the ability of select resident vaginal bacteria to numerically dominate and, therefore, the definition of a "normal" vaginal microbiota will substantially differ between individual healthy women.

ABSTRACT

The early diagnosis of breast cancer can improve treatment and prognosis. We sought to evaluate whether the serum concentration of the 70 kDa heat shock protein (HSPA1A) was elevated in Brazilian women with breast cancer, and if levels correlated with tumor characteristics. This was a cross-sectional, analytical, case-control exploratory study performed at The University of São Paulo School of Medicine. From September 2017 to December 2018, 68 women with breast cancer and 59 controls were recruited. The HSPA1A concentration in serum samples was determined by ELISA by individuals blinded to the clinical data. The mean ages in the study and control groups were 54.9 and 52.0 years, respectively. The median serum levels of HSPA1A were elevated in women with breast cancer (1037 pg/ml) compared with controls (300 pg/ml) (p < 0.001). Elevated HSPA1A levels were associated with advanced histological tumor grade (p < 0.001) and with the cell proliferation index (KI67) (p = 0.0418). The HSPA1A concentration was similar in women with different histological subtypes, nuclear grade, hormone receptor expression, HER2 status and the presence or absence of angiolymphatic invasion. Elevated serum HSPA1A in Brazilian women with advanced histological grade and proliferation index breast cancer supports the potential value of additional investigation on larger and more varied populations to verify the value of HSPA1A detection as a component of breast cancer diagnosis and progression.

ABSTRACT

Introduction: The majority of pregnant women with a short cervix will deliver at term and, thus, may unnecessarily receive advanced monitoring and treatment. It is still necessary to define more accurately which sub-population of women with a short cervix is at elevated risk for early delivery. Objective: To determine if vaginal microbiome composition influenced the rate of spontaneous preterm birth in women with a short cervical length. Methods: In an exploratory, observational prospective study, vaginal secretions were obtained from 591 women at 21­24 week gestation. Vaginal microbiome composition was determined by analyzing the V1­V3 region of the bacterial 16S ribosomal RNA gene. Results: Lactobacillus crispatus was numerically dominant in the vagina in 41.7% of subjects, followed by L. iners in 32% and Gardnerella vaginalis in 12%. In women whose cervix was ≤25mm, the sensitivity to predict an spontaneous preterm birth was 11.8%. However, when L. crispatus was not the dominant vaginal bacterium, this sensitivity increased to 81.8%. Similarly, in women with a cervical length ≤30mm, the sensitivity to predict an spontaneous preterm birth increased from 21.7 to 78.3% when L. crispatus was not the dominant vaginal bacterium.In women with a prior spontaneous preterm birth and a cervix ≤25 or ≤30mm, L. crispatus dominance was also associated with a reduced rate of spontaneous preterm birth in the current pregnancy (p<0.001). Conclusion: In pregnant women with a cervix ≤25mm or ≤30mm, the risk for an spontaneous preterm birth is increased if L. crispatus is not dominant in the vagina.


Introdução: A maioria das mulheres grávidas com colo do útero curto dará à luz a termo e, portanto, pode receber desnecessariamente monitoramento e tratamento avançados. Permanece a necessidade de definir com mais precisão qual subpopulação de mulheres com colo do útero curto está em risco elevado de parto prematuro. Objetivo: Determinar se a composição do microbioma vaginal influenciou a taxa de parto prematuro espontâneo em mulheres com colo curto. Métodos: Em um estudo prospectivo exploratório observacional, os conteúdos vaginais foram obtidos de 591 mulheres com 21­24 semanas de gestação. A composição do microbioma vaginal foi determinada pela análise da região V1­V3 do gene de RNA ribossômico bacteriano 16S. Resultados: Lactobacilluscrispatus foi numericamente dominante na vagina em 41,7% dos indivíduos, seguido por L. iners em 32% e Gardnerella vaginalis em 12%. Em mulheres cujo colo do útero era <25 mm, a sensibilidade para prever uma taxa de parto prematuro espontâneo foi de 11,8%. No entanto, quando L. crispatus não era a bactéria vaginal dominante, essa sensibilidade aumentou para 81,8%. Da mesma forma, em mulheres com comprimento cervical <30 mm, a sensibilidade para prever uma taxa de parto prematuro espontâneo aumentou de 21,7 para 78,3% quando L. crispatus não era a bactéria vaginal dominante. Em mulheres com taxa de parto prematuro espontâneo anterior e colo do útero <25 ou <30 mm, a dominância de L. crispatus também foi associada a uma taxa reduzida de taxa de parto prematuro espontâneo na gravidez atual (p<0,001). Conclusão: Em mulheres grávidas com colo do útero <25 ou <30 mm, o risco de parto prematuro espontâneo é aumentado se L. crispatus não for dominante na vagina.

ABSTRACT

Torquetenovirus (TTV) is a nonpathogenic endogenous virus whose abundance varies with the extent of immune system activation. We determined if the TTV titer in the vagina of pregnant women was associated with vaginal microbiota composition and levels of compounds in vaginal secretions. Vaginal TTV and microbiota composition in 494 second trimester pregnant women were identified by gene amplification and analysis. Vaginal matrix metalloproteinases (MMPs), tissue inhibitors of MMP (TIMP) and lactic acid isomers were measured by ELISA. Dominance was defined as the relative abundance of a specific bacterium or species at >50% of the total number of bacteria identified. Clinical data were obtained by chart review. The median log10 TTV titer was lowest when Lactobacillus species other than L. iners were dominant (<1.0) as compared to when L. iners (4.1, p = 0.0001), bacteria other than lactobacilli (4.5, p = 0.0016) or no bacterium (4.7, p = 0.0009) dominated. The TTV titer was inversely proportional to L. crispatus abundance (p<0.0001) and directly proportional to levels of G. vaginalis (p = 0.0008) and L. iners (p = 0.0010). The TTV titer was proportional to TIMP-1, TIMP-2, MMP-8 and MMP-9 abundance (p≤0.0002) and inversely proportional to the level of D-lactic acid (p = 0.0024). We conclude that the association between variations in the TTV titer and the relative abundance of specific bacterial species and vaginal compounds indicates that local changes in immune status likely influence vaginal fluid composition.

ABSTRACT

BACKGROUND: Predictors of spontaneous preterm birth in primigravid women remain undetermined. AIM: We evaluated whether biomarkers in vaginal secretions and/or differences in the dominant bacterium in the vaginal microbiome predicted the risk for spontaneous preterm birth in primigravid women with a cervical length >25mm. STUDY DESIGN: In a prospective study, 146 second trimester pregnant women with their first conception and a cervix >25mm were enrolled. The vaginal microbiome composition was characterized by analysis of 16S ribosomal RNA gene sequences. The concentrations of d- and l-lactic acid, matrix metalloproteinase (MMP) 2, 8 and 9 and tissue inhibitor of metalloproteinase (TIMP) 1 and 2 in vaginal secretions were measured by ELISA. Cervical length was determined by vaginal ultrasonography. Pregnancy outcome data were subsequently collected. There was a spontaneous preterm birth (SPTB) in 13 women (8.9%) while in an additional 8 women (5.5%) preterm delivery was medically indicated. Lactobacillus iners was the dominant vaginal bacterium in 61.5% of women with a SPTB but only in 31.2% of those who delivered at term (p = .0354). The vaginal concentration of TIMP-1 (p = .0419) and L-lactic acid (p = .0495) was higher in women with a SPTB as compared to those who delivered at term. Lactobacillus iners dominance was associated with elevated levels of TIMP-1 (p = .0434) and TIMP-2 (p = .0161) and lower levels of D-lactic acid (p < .0001) compared to when L. crispatus was dominant. CONCLUSION: In this exploratory study of primigravid women, elevations in vaginal TIMP-1 and L- lactic acid and L. iners dominance in the vaginal microbiome are associated with an increased occurrence of SPTB.

ABSTRACT

PURPOSE: Identification of low-cost protocols to identify women at elevated susceptibility to develop cervical intra-epithelial abnormalities would aid in more individualized monitoring. We evaluated whether quantitation of the D- and L-lactic acid isomers in vaginal secretions could differentiate women with normal cervical epithelia from those with a low (LSIL) or high (HSIL) grade squamous intraepithelial lesion or with cervical cancer. METHODS: Vaginal samples, collected from 78 women undetgoing cervical colposcopy and biopsy, were tested for pH, bacterial composition by Gram stain (Nugent score) and concentrations of D- and L-lactic acid by a colorimetric assay. RESULTS: Subsequent diagnosis was 23 women with normal cervical epithelium, 10 with LSIL, 43 with HSIL and 2 with cervical cancer. Vaginal pH and Nugent score were comparable in all subject groups. The concentration of L-lactic acid, but not D-lactic acid, as well as the L/D-lactic acid ratio, were significantly elevated (p < 0.01) in women with HSIL and cervical cancer. CONCLUSION: Comparative measurement of vaginal D- and L-lactic acid isomers may provide a low-cost alternative to identification of women with an elevated susceptibility to cervical abnormalities.

ABSTRACT

Pelvic Inflammatory Disease is a topic included in the Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health in 2020. Pelvic inflammatory disease is an upper female genital tract acute infection due to canalicular spread of endogenous cervicovaginal microorganisms and especially the sexually transmitted microorganisms. Standing out among the etiological agents involved are Chlamydia trachomatis and Neisseria gonorrhoeae. The main sequelae are chronic pelvic pain, infertility, and ectopic pregnancy. Clinical diagnosis is the most important practical approach. Antibiotic treatment must start immediately after the clinical suspicion. Guidelines for health service managers and health professionals on diagnostic tests, treatment, follow-up, counseling, notification, handling sexual partners and special populations are described. Given the increased availability of the molecular biology techniques in Brazil, C. trachomatis and N. gonorrhoeae screening are recommended as a disease prevention strategy. Pelvic inflammatory disease is one of the most significant sexually transmitted infections, and in most cases, it is a main consequence of cervicitis.

ABSTRACT

Pelvic Inflammatory Disease is a topic included in the Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health in 2020. Pelvic inflammatory disease is an acute infection of the upper female genital tract due to canalicular spread of endogenous cervicovaginal microorganisms, in particular sexually transmitted organisms. Standing out among the etiological agents involved are Chlamydia trachomatis and Neisseria gonorrhoeae. The most important sequels are chronic pelvic pain, infertility and ectopic pregnancy. Clinical diagnosis is the most important practical approach. Antibiotic treatment should start immediately upon clinical suspicion. The article contains guidance for health service managers and health professionals on diagnostic tests, treatment, follow-up, counseling, notification, handling of sexual partnerships and special populations. In view of increased availability of the molecular biology technique in Brazil, C. trachomatis and N. gonorrhoeae screening is recommended as a disease prevention strategy.

ABSTRACT

PURPOSE: To investigate associations between bacterial species in the vagina in mid-trimester pregnant women from Brazil. METHODS: The vaginal microbiome in 613 subjects was identified by analysis of the V1-V3 region of bacterial 16S ribosomal RNA and the relative prevalence of individual bacteria were determined. RESULTS: The bacterial species present in the greatest number of women were Lactobacillus crispatus (306 women), L. iners (298 women) and Gardnerella vaginalis (179 women). When present in the vagina, L. crispatus was the most abundant bacterium more than 85% of the time. In contrast, L. iners and G. vaginalis were most abundant in 63% and 41% of women who were positive for these microorganisms, respectively (p < 0.0001 vs. L. crispatus). The proportion of L. crispatus was negatively associated with the proportions of L. iners, L. jensenii, L. gasseri, G. vaginalis, Megasphaera, Atopobium vaginae and Prevotella (p < 0.0001). In contrast, the proportion of G. vaginalis was positively associated with levels of Megasphaera, A. vaginae and Prevotella (p < 0.0001) while L. iners proportion was unrelated to the proportion of L. jensenii, G. vaginalis, Megasphaera, A. vaginae or Prevotella. CONCLUSION: The composition of the vaginal microbiota in mid-trimester pregnant women is influenced by the relative concentrations of L. crispatus, L. iners and G. vaginalis.

ABSTRACT

INTRODUCTION: Torque teno virus (TTV) is a non-pathogenic virus present in body fluids. Its titer in the circulation increases in association with immune suppression, such as in HIV-infected individuals. We evaluated if the TTV titer in saliva from HIV-positive individuals undergoing antiretroviral therapy (ART) was related to the circulating CD4+ T lymphocyte concentration and the HIV titer. METHODS: Saliva was collected from 276 asymptomatic individuals undergoing ART, and an additional 48 individuals positive for AIDS-associated Kaposi's Sarcoma (AIDS-KS). The salivary TTV titer was measured by gene amplification analysis. The circulating CD4+ T lymphocyte and HIV levels were obtained by chart review. RESULTS: TTV was detectable in saliva from 80% of the asymptomatic subjects and 87% of those with AIDS-KS. In the asymptomatic group the median log10 TTV titer/ml was 3.3 in 200 males vs. 2.4 in 76 females (p < 0.0001). TTV titer/ml was 3.7 when HIV was acquired by intravenous drug usage, 3.2 when by sexual acquisition and 2.4 when blood transfusion acquired. The salivary TTV titer was inversely correlated with the circulating CD4+ T lymphocyte level (p < 0.0001) and positively correlated with the circulating HIV concentration (p = 0.0005). The median salivary TTV titer and circulating HIV titer were higher, and the CD4+ count was lower, in individuals positive for AIDS-KS than in the asymptomatic subjects (p < 0.0001). CONCLUSION: The TTV titer in saliva is a potential biomarker for monitoring immune status in individuals undergoing ART.

ABSTRACT

OBJECTIVES: Short cervical length is a predictor of preterm birth. We evaluated if there were racial differences in variables associated with cervical length in pregnant Brazilian women. METHODS: Cervical length was determined by vaginal ultrasound in 414 women at 21 weeks gestation. All women were seen at the same clinic and analyzed by the same investigators. Women found to have a short cervix (≤25 mm) received vaginal progesterone throughout gestation. Composition of the vaginal microbiome was determined by analysis of the V1-V3 region of the gene coding for bacterial 16S ribosomal RNA. Demographic, clinical and outcome variables were determined by chart review. Subjects were 53.4% White, 37.2% mixed race and 9.4% Black. RESULTS: Pregnancy, medical history and education level were similar in all groups. Mean cervical length was shorter in Black women (28.4 mm) than in White (32.4 mm) or mixed race (32.8 mm) women (p≤0.016) as was the percentage of women with a short cervix (23.1, 12.2, 7.8% in Black, White, mixed race respectively) (p≤0.026). Mean cervical length increased with maternal age in White (p=0.001) and mixed race (p=0.045) women but not Black women. There were no differences in bacterial dominance in the vaginal microbiota between groups. Most women with a short cervix delivered at term. CONCLUSIONS: We conclude that Black women in Brazil have a shorter cervical length than White or mixed race women independent of maternal age, pregnancy and demographic history or composition of the vaginal microbiome.

Pelvic inflammatory disease is an acute infection of the upper female genital tract due to canalicular spread of endogenous cervicovaginal microorganisms, in particular sexually transmitted organisms. Standing out among the etiological agents involved are Chlamydia trachomatis and Neisseria gonorrhoeae. The most important sequels are chronic pelvic pain, infertility and ectopic pregnancy. Clinical diagnosis is the most important practical approach. Antibiotic treatment should start immediately upon clinical suspicion. The article contains guidance for health service managers and health professionals on diagnostic tests, treatment, follow-up, counseling, notification, handling of sexual partnerships and special populations. In view of increased availability of the molecular biology technique in Brazil, C. trachomatis and N. gonorrhoeae screening is recommended as a disease prevention strategy.


El tema de la enfermedad inflamatoria pélvica está incluido en el Protocolo Clínico y Directrices Terapéuticas para la Atención Integral para Personas con Infecciones de Transmisión Sexual, publicado por el Ministerio de Salud de Brasil en 2020. La enfermedad inflamatoria pélvica es una infección aguda del tracto genital superior femenino resultante del ascenso canalicular de microorganismos cervicovaginales endógenos y, principalmente, los de transmisión sexual. Entre los agentes etiológicos involucrados, se destacan Chlamydia trachomatis y Neisseria gonorrhoeae. Las secuelas más importantes son: dolor pélvico crónico, infertilidad y embarazo ectópico. El diagnóstico clínico es el enfoque práctico más importante. El tratamiento con antibiótico debe iniciarse inmediatamente ante la sospecha clínica. Se describen pautas para gestores y profesionales de la salud sobre pruebas de diagnóstico, tratamiento, seguimiento, asesoramiento, notificación, manejo de parejas sexuales y poblaciones especiales. Con la mayor disponibilidad de la técnica de biología molecular, se recomienda el cribado de C. trachomatis y N. gonorrhoeae como estrategia preventiva para la enfermedad.

ABSTRACT

Resumo O tema doença inflamatória pélvica está contemplado no Protocolo Clínico e Diretrizes Terapêuticas para Atenção Integral às Pessoas com Infecções Sexualmente Transmissíveis, publicado pelo Ministério da Saúde do Brasil em 2020. A doença inflamatória pélvica é a infecção aguda do trato genital superior feminino decorrente da ascensão canalicular de microrganismos cervicovaginais endógenos e, principalmente, os de transmissão sexual. Entre os agentes etiológicos envolvidos, destacam-se Chlamydia trachomatis e Neisseria gonorrhoeae. As sequelas mais importantes são dor pélvica crônica, infertilidade e gravidez ectópica. O diagnóstico clínico apresenta-se como a abordagem prática mais importante. O tratamento com antibióticos deve ser iniciado imediatamente diante da suspeição clínica. Descrevem-se orientações para gestores e profissionais de saúde sobre testes diagnósticos, tratamento preconizado, seguimento, aconselhamento, notificação, manejo de parcerias sexuais e de populações especiais. Com a maior disponibilidade da técnica de biologia molecular no Brasil, recomenda-se o rastreio de C. trachomatis e N. gonorrhoeae como estratégia preventiva da doença.

ABSTRACT

Abstract Pelvic Inflammatory Disease is a topic included in the Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health in 2020. Pelvic inflammatory disease is an upper female genital tract acute infection due to canalicular spread of endogenous cervicovaginal microorganisms and especially the sexually transmitted microorganisms. Standing out among the etiological agents involved are Chlamydia trachomatis and Neisseria gonorrhoeae. The main sequelae are chronic pelvic pain, infertility, and ectopic pregnancy. Clinical diagnosis is the most important practical approach. Antibiotic treatment must start immediately after the clinical suspicion. Guidelines for health service managers and health professionals on diagnostic tests, treatment, follow-up, counseling, notification, handling sexual partners and special populations are described. Given the increased availability of the molecular biology techniques in Brazil, C. trachomatis and N. gonorrhoeae screening are recommended as a disease prevention strategy.
