[Preliminary Study on the Identification of Aerobic Vaginitis by Artificial Intelligence Analysis System]. / 人工智能分析系统对需氧菌性阴道炎的判读方法初探.

Objective: To develop an artificial intelligence vaginal secretion analysis system based on deep learning and to evaluate the accuracy of automated microscopy in the clinical diagnosis of aerobic vaginitis (AV). Methods: In this study, the vaginal secretion samples of 3769 patients receiving treatment at the Department of Obstetrics and Gynecology, West China Second Hospital, Sichuan University between January 2020 and December 2021 were selected. Using the results of manual microscopy as the control, we developed the linear kernel SVM algorithm, an artificial intelligence (AI) automated analysis software, with Python Scikit-learn script. The AI automated analysis software could identify leucocytes with toxic appearance and parabasal epitheliocytes (PBC). The bacterial grading parameters were reset using standard strains of lactobacillus and AV common isolates. The receiver operating characteristic (ROC) curve analysis was used to determine the cut-off value of AV evaluation results for different scoring items were obtained by using the results of manual microscopy as the control. Then, the parameters of automatic AV identification were determined and the automatic AV analysis scoring method was initially established. Results: A total of 3769 vaginal secretion samples were collected. The AI automated analysis system incorporated five parameters and each parameter incorporated three severity scoring levels. We selected 1.5 µm as the cut-off value for the diameter between Lactobacillus and common AV bacterial isolates. The automated identification parameter of Lactobacillus was the ratio of bacteria ≥1.5 µm to those <1.5 µm. The cut-off scores were 2.5 and 0.5, In the parameter of white blood cells (WBC), the cut-off value of the absolute number of WBC was 103 µL－1 and the cut-off value of WBC-to-epithelial cell ratio was 10. The automated identification parameter of toxic WBC was the ratio of toxic WBC toWBC and the cut-off values were 1% and 15%. The parameter of background flora was bacteria<1.5 µm and the cut-off values were 5×103 µL－1 and 3×104 µL－1. The parameter of the parabasal epitheliocytes was the ratio of PBC to epithelial cells and the cut-off values were 1% and 10%. The agreement rate between the results of automated microscopy and those of manual microscopy was 92.5%. Out of 200 samples, automated microscopy and manual microscopy produced consistent scores for 185 samples, while the results for 15 samples were inconsistent. Conclusion: We developed an AI recognition software for AV and established an automated vaginal secretion microscopy scoring system for AV. There was good overall concordance between automated microscopy and manual microscopy. The AI identification software for AV can complete clinical lab examination with rather high objectivity, sensitivity, and efficiency, markedly reducing the workload of manual microscopy.

Aerobic vaginitis is associated with carbonic anhydrase IX in cervical intraepithelial neoplasia.

The aim of this study was to analyze the association between vaginal microbiota, carbonic anhydrase IX (CAIX) and histological findings of cervical intraepithelial neoplasia (CIN). The study included 132 females, among them 66 were diagnosed with high-grade intraepithelial lesion (CIN2, CIN3, and cancer), 14 with low-grade disease, and 52 assigned to the control group. An interview focused on the behavior risk factors, together with vaginal fluid pH measurement, wet mount microscopy, detection of Chlamydia trachomatis, and Trichomonas vaginalis were performed. After colposcopy, high-grade abnormalities were detected via direct biopsies and treated with conization procedure. Conuses were immuno-stained with CAIX antibody. The histological findings were CIN1 (n = 14), and CIN2+ (included CIN2 (n = 10), CIN3 (n = 49), and cancer (n = 7; squamous cell carcinomas)). Prevalence of bacterial vaginosis (BV) was similar between the groups. Moderate or severe aerobic vaginitis (msAV) was diagnosed more often among CIN2+ (53.0%) than CIN1 (21.4%). Moderate or strong immunostaining of CAIX (msCAIX) was not detected among CIN1 cases. Thus, msAV was prevalent in CAIX non-stained group (p = 0.049) among CIN2 patients. Co-location of msAV and msCAIX was found in CIN3. Regression model revealed that msAV associated with high-grade cervical intraepithelial neoplasia independently from smoking and the number of partners.

Lactobacillus as probiotics: opportunities and challenges for potential benefits in female reproductive health.

The growing interest of the scientific community in the study of probiotics has gathered valuable data about its beneficial effects for multiple clinical conditions. This data also provides evidence for the functions and properties of probiotics and how they contribute to health benefits by influencing normal microbiota. Lactobacillus is an important genus which has long been utilized in the food industry and is also found as normal oral, intestinal and vaginal microbiota. Lactobacillus has shown multiple health benefits but its relative importance as a probiotic is majorly explored for gastrointestinal health. Healthy vaginal microbiota typically harbors Lactobacillus spp. providing several health benefits for female reproductive health, but there is more data required in order to compare the relative benefits with probiotic Lactobacillus added through either natural food sources or with standard probiotics supplements. The present article discusses the current status of knowledge about vaginal Lactobacillus as a probiotic and also compares the potential of probiotics from natural sources and through supplements along with recent approaches in this area.

An effective non-hormonal option with high tolerability for mild to moderate symptoms of vaginal dryness associated with menopause.

OBJECTIVES: The efficacy and tolerability of a non-hormonal pessary (that forms an oil-in-water emollient with the vaginal fluid) were assessed for the treatment of symptoms of vaginal dryness associated with menopause. STUDY DESIGN: Seventy-nine postmenopausal women (mean age 60.8 ± 6.5 years) with mild to moderate symptoms of vaginal dryness (including dyspareunia) were enrolled in this open-label, prospective, post-market clinical follow-up trial, conducted in 2022 by one research center in Germany. The investigational pessary was applied for the first 7 days once daily and the subsequent 31 days twice a week, at bedtime. A treatment-free period of 6 days completed the trial. MAIN OUTCOME MEASURES: During the trial, participants filled out questionnaires that enabled the calculation of a total severity score for subjective symptoms of atrophy-related vaginal dryness and impairment of daily as well as sexual life. Furthermore, vaginal health index and safety were studied. RESULTS: A rapid and significant reduction in the severity scores for symptoms was observed over the 38-day course of treatment and beyond. Quality of life assessed by DIVA (day-to-day impact of vaginal aging) questionnaire, dyspareunia and vaginal health index also clearly improved. The tolerability was mainly rated as "good to very good" by the investigator and 94.9 % of participants. The vast majority were very satisfied with the simple and pleasant handling. No serious adverse events occurred. CONCLUSION: Overall, the presented data suggest that the investigated non-hormonal pessary is an effective and well tolerated treatment option for vaginal symptoms associated with dryness, thus improving quality of life for women, even those who are sexually active. CLINICALTRIALS: gov identifier NCT05211505.

Functional testing is a complementary tool for the diagnosis of vaginitis.

OBJECTIVE: Vaginal microbiota evaluation is a methodology widely used in China to diagnose various vaginal inflammatory diseases. Although vaginal microbiota evaluation has many advantages, it is time-consuming and requires highly skilled and experienced operators. Here, we investigated a six-index functional test that analyzed pH, hydrogen peroxide (H2O2), leukocyte esterase (LEU), sialidase (SNA), ß-glucuronidase (GUS), and acetylglucossidase (NAG), and determined its diagnostic value by comparing it with morphological tests of vaginal microbiota. MATERIALS AND METHODS: The research was conducted using data extracted from the Laboratory Information System of Women and Children's Hospital. A total of 4902 subjects, ranging in age from 35.4 ± 9.7 years, were analyzed. During the consultation, a minimum of two vaginal swab specimens per patient were collected for both functional and morphological testing. Fisher's exact was used to analyze data using SPSS. RESULTS: Of the 4,902 patients, 2,454 were considered to have normal Lactobacillus morphotypes and 3,334 were considered to have normal dominant microbiota. The sensitivity and specificity of H2O2-indicating Lactobacillus morphotypes were 91.3% and 25.28%, respectively, while those of pH-indicating Lactobacillus morphotypes were 88.09% and 59.52%, respectively. The sensitivity and specificity of H2O2-indicating dominant microbiota were 91.3% and 25.3%, respectively, while those of pH-indicating dominant microbiota were 86.27% and 64.45%, respectively. The sensitivity and specificity of NAG for vulvovaginal candidiasis were 40.64% and 84.8%, respectively. For aerobic vaginitis, GUS sensitivity was low at 0.52%, while its specificity was high at 99.93%; the LEU sensitivity and specificity values were 94.73% and 27.49%, respectively. Finally, SNA sensitivity and specificity for bacterial vaginosis were 80.72% and 96.78%, respectively. CONCLUSION: Functional tests (pH, SNA, H2O2, LEU) showed satisfactory sensitivity for the detection of vaginal inflammatory diseases. However, these tests lacked specificity, making it difficult to accurately identify specific pathologies. By contrast, NAG and GUS showed excellent specificity in identifying vaginal inflammatory diseases, but their sensitivity was limited. Therefore, functional tests alone are not sufficient to diagnose various vaginal inflammatory diseases. When functional and morphological tests are inconsistent, morphological tests are currently considered the preferred reference method.

Infectious hepatitis E virus excreted into the vagina.

Hepatitis E virus (HEV) persists in the male genital tract that associates with infertility. However, the presence of HEV in the female genital tract is unreported. Vaginal secretions, cervical smears, and cervix uteri were collected to explore the presence of HEV in the female genital tract. HEV RNA and/or antigens were detected in the vaginal secretions, cervical smears, and the cervix uteri of women. The infectivity of HEV excreted into vaginal secretions was further validated in vitro. In addition, HEV replicates in the female genital tract were identified in HEV-infected animal models by vaginal injection or vaginal mucosal infection to imitate sexual transmission. Serious genital tract damage and inflammatory responses with significantly elevated mucosal innate immunity were observed in women or animals with HEV vaginal infection. Results demonstrated HEV replicates in the female genital tract and causes serious histopathological damage and inflammatory responses.

Genome-wide association study in Estonia reveals importance of vaginal epithelium associated genes in case of recurrent vaginitis.

Recurrent vaginitis is a leading reason for visiting a gynaecologist, with bacterial vaginosis (BV) and vulvovaginal candidiasis (VVC) being the most common diagnoses. Reasons and mechanisms behind their recurrent nature are poorly understood. We conducted a genome-wide association study (GWAS) to find possible genetic risk factors for recurrent vaginitis using data from a large population-based biobank, the Estonian Biobank. The study included 6870 cases (at least two episodes of vaginitis) and 5945 controls (no vaginitis episodes). GWAS approach included single marker and gene-based analyses, followed by functional annotation of associated variants and candidate gene mapping.In single marker analysis, one statistically significant (P = 7.8 × 10-9) variant rs1036732378 was identified on chromosome 10. The gene-based association analysis identified one gene, KRT6A, that exceeded the recommended significance threshold (P = 2.6 × 10-6). This is a member of the keratin protein family and is expressed during differentiation in epithelial tissues.Functional mapping and annotation of genetic associations by using adjusted significance level identified 22 potential risk loci that may be associated with recurrent vaginitis phenotype. Comparison of our results with previous studies provided nominal support for LBP (associated with immune response to vaginal bacteria) and PRKCH genes (possible role in keratinocyte differentiation and susceptibility to candidiasis).In conclusion, this study is the first highlighting a potential role of the vaginal epithelium in recurrent vaginitis.

Recurrent Infectious Vaginitis: A Practical Approach for the Primary Care Clinician.

Recurrent infectious vaginitis can lead to significant morbidity, patient frustration, and health care costs. The most common causes are bacterial vaginosis (BV) and vulvovaginal candidiasis (VVC); however, other infectious and noninfectious etiologies should be considered in patients with recurrent symptoms. A detailed history and physical examination with appropriate testing at the time of symptoms is critical to establishing a correct diagnosis. Management options for recurrent BV and VVC are limited. Complex cases including those with atypical symptoms, negative testing for common causes, refractory symptoms despite appropriate therapy or recurrences during suppressive therapy will require referral to specialist care.

Molecular typing and antifungal susceptibility profile of Candida krusei bloodstream isolates from Türkiye.

Candida krusei also known as Pichia kudriavzevii is a potentially multidrug-resistant yeast because it is intrinsically resistant to fluconazole and develops acquired resistance to echinocandins and polyenes. Here, we aim to provide a better understanding of the epidemiology and transmission modes of C. krusei infections by comparing invasive bloodstream (n = 35) and non-invasive vaginal (n = 20) C. krusei isolates. The genetic relatedness of the isolates was assessed using a newly described short tandem repeat (STR) analysis and their sensitivity to eight antifungal compounds was evaluated by antifungal susceptibility testing using the CLSI microbroth dilution method. All C. krusei isolates revealed unique STR genotypes, indicating the absence of clonal transmission in the study group. Furthermore, no drug-resistant or non-wild-type isolates were identified. Our findings demonstrated high resolution of STR genotyping for the detection and simultaneous genetic analysis of multiple C. krusei strains in clinical samples and excellent in vitro activity of common antifungal agents against invasive strains.

Interplay between Staphylococcus aureus and the vaginal microbiota.

Staphylococcus aureus is a proficient colonizer and opportunistic pathogen which can lead to vaginal dysbiosis, aerobic vaginitis, or life-threatening menstrual toxic shock syndrome. Here we explore the complex but underappreciated interactions that S. aureus may impose on the vaginal environment leading to additional disease outcomes.

Bacterial Vaginosis and Vulvovaginal Candidiasis Pathophysiologic Interrelationship.

Among the infectious causes of vulvovaginal symptoms, bacterial vaginosis (BV) and vulvovaginal candidiasis (VVC) dominate. Apart from infrequent mixed infections, both are considered independent and caused by unrelated pathogenic mechanisms. Clinical experience, however, is strongly suggestive that in some populations these infections are linked with recurrent BV (RBV) serving as the dominant etiopathogenic trigger for development of recurrent VVC (RVVC) with profound clinical and therapeutic consequences. The biologic basis for this critical interrelationship is discussed and suggests that as a consequence of BV dysbiosis, and not necessarily because of antibiotics prescribed, immune defenses are compromised, neutralizing vaginal yeast tolerance. The consequent BV-induced vaginal proinflammatory environment predisposes to mixed infection or consecutive episodes of post-treatment VVC. Recurrent BV and repeated antimicrobial drug exposure also predispose to acquired fluconazole resistance in C. albicans isolates, contributing to refractory vulvovaginal candidiasis.

Non-antibiotic Treatment Modalities for Bacterial Vaginosis.

Caused by an imbalance in the vaginal microbiome, bacterial vaginosis (BV) is among the most commonly occurring vaginal infections in women of childbearing age. If untreated, BV may have a detrimental impact on the obstetric and gynecological health of an individual. To date, treatment for BV includes a regimen of antibiotics and avoidance of relevant risk factors. Since recurrence and reinfection are frequently observed in patients, pharmaceutical treatment for BV remains ineffective nevertheless. Repeated exposure to antibiotics could precipitate drug-resistant strains. The severity of this problem leads to the emergence of non-antimicrobial therapies. This article aims to provide a review on the types and efficacy of various alternative, non-antimicrobial therapeutic regimens.

In vivo studies could not confirm in vitro prophylactic synergism between Moringa essential oil and Lactobacillus reuteri (MT180537)

Abstract Aerobic vaginitis (AV) is a recently defined vaginal recurring infection, which is treated with antibiotics. However, excessive and prolonged use of antibiotics disrupts healthy vaginal microflora and leads to the emergence of antibiotic resistance among pathogens. This situation has directed researchers to explore alternative antimicrobials. The current study describes in vitro and in vivo antimicrobial efficacy and pharmaceutical interactions between plant essential oils (EOs) and five lactic acid bacteria (LABs), isolated from the healthy vagina, against E. faecalis, one of the major etiological agents of AV. In vitro experiments confirm good antimicrobial activity of both plant EOs and cell free supernatant (CFS) from LABs. Based on high antimicrobial efficacy, Moringa essential oil (MO) was selected to determine its nature of interaction with CFS of five LAB strains. Synergism was recorded between MO and CFS of L. reuteri (MT180537). To validate in vitro findings, prophylactic responses of individual and synergistic application of MO and L. reuteri (MT180537) were evaluated in an E. faecalis (MW051601) induced AV murine model. The prophylactic efficacy was evidenced by a reduction in intensity of clinical symptoms, E. faecalis (MW051601) count per vaginal tissue along with a reduction in AV associated changes in histological markers of infection in animals receiving Moringa essential oil and L. reuteri (MT180537) alone or in combination. However, significant synergism between Moringa essential oil and L. reuteri (MT180537) could not be observed. Our data confirms the importance of in vivo experiments in deducing pharmacological interactions.

Resumo Vaginite aeróbica (VA) é uma infecção vaginal recorrente definida recentemente, que é tratada com antibióticos. No entanto, o uso excessivo e prolongado de antibióticos perturba a microflora vaginal saudável e leva ao surgimento de resistência aos antibióticos entre os patógenos. Esta situação levou os pesquisadores a explorar antimicrobianos alternativos. O presente estudo descreve a eficácia antimicrobiana in vitro e in vivo e as interações farmacêuticas entre óleos essenciais vegetais (OE) e cinco bactérias lácticas (BAL), isoladas de vagina sã, contra E. faecalis, um dos principais agentes etiológicos da AV. Os experimentos in vitro confirmam a boa atividade antimicrobiana de ambos os EOs de plantas e sobrenadante livre de células (CFS) de LABs. Com base na alta eficácia antimicrobiana, o óleo essencial de Moringa (MO) foi selecionado para determinar sua natureza de interação com o sobrenadante livre de células (CFS) de cinco cepas de LAB. Sinergismo foi registrado entre MO e CFS de L. reuteri (MT180537). Para validar os resultados in vitro, as respostas profiláticas da aplicação individual e sinérgica de MO e L. reuteri (MT180537) foram avaliadas em um modelo murino AV induzido por E. faecalis (MW051601). A eficácia profilática foi evidenciada por uma redução na intensidade dos sintomas clínicos, contagem de E. faecalis (MW051601) por tecido vaginal, juntamente com uma redução nas alterações associadas a AV nos marcadores histológicos de infecção em animais que receberam óleo essencial de Moringa e L. reuteri (MT180537) sozinho ou em combinação. No entanto, não foi possível observar sinergismo significativo entre o óleo essencial de Moringa e L. reuteri (MT180537). Nossos dados confirmam a importância dos experimentos in vivo na dedução de interações farmacológicas.

Genitourinary Syndrome of Menopause: A Narrative Review Focusing on Its Effects on the Sexual Health and Quality of Life of Women.

Genitourinary syndrome of menopause (GSM) is a progressive condition due to a hypoestrogenic state affecting perimenopausal and menopausal women. GSM was previously known as urogenital syndrome, vulvovaginal atrophy, or atrophic vaginitis. The term vulvovaginal atrophy did not encompass the symptoms of the urinary tract like incontinence, urgency, and discomfort, or allude that it is due to a hypoestrogenic state. Although a significant segment of the population is affected by GSM, it is very sparsely studied, detected, and treated. GSM affects the quality of life and sexual health of most menopausal women suffering from it. Only a few healthcare providers ask about the symptoms of GSM and a tiny percentage of women seek consultation for it. This may be because they are either embarrassed or believe it to be a part of the natural process of aging. As the life expectancy of women has increased in general, the prevalence of GSM has also risen, while it still remains underdiagnosed and untreated. Properly educating women so that they can seek consultation regarding symptoms of GSM, and training healthcare professionals about communicating with the patient, as well as correctly identifying, diagnosing, and managing the patient are all important to overcome this communication barrier. Once we cross the barrier of diagnosing patients with GSM, we still have to manage the patients with tailor-made prescriptions according to the severity of the symptoms and their preferences. While there are various treatment options, the most effective one is low-dose topical estrogen therapy. In this review, we intend to explore the existing knowledge about GSM and its effect on the quality of life and sexual health of women along with the treatment options for managing and reversing the effects of GSM.

PREVALENCE OF AEROBIC VAGINITIS AFTER GYNECOLOGICAL SURGERIES AND ASSOCIATED ADVERSE PREGNANCY OUTCOME IN UKRAINE.

OBJECTIVE: Aim: To determine prevalence of Aerobic Vaginitis (AV) after gynecologic surgery, risk factors and antimicrobial resistance of responsible pathogens, and adverse pregnancy outcomes in Ukraine. PATIENTS AND METHODS: Materials and Methods: Multicenter retrospective cohort study was conducted from January 2020 to December 2022 in fifteen medical clinics from eight regions of Ukraine. Smears were analyzed using Donders' classification method and Dong's modified AV diagnosis for Gram stains. Definitions of HAIs were adapted from the CDC/NHSN. Antibiotic susceptibility testing of bacteria was determined by Kirby-Bauer disc diffusion test according to the protocol of the EUCAST. RESULTS: Results: Prevalence of AV among women's undergoing gynecologic surgery in Ukraine was 68.7%. Of the total AV cases, 70.3% were in non-pregnant and 29,7% in pregnant women. The most common pathogen of AV was Escherichia coli, followed by Enterococcus faecalis, Streptococcus agalactiae, Staphylococcus aureus, Enterococcus faecium, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Among the S. aureus strains, 11,6% of MRSA (Methicillin resistant S.aureus) were isolated whereas none of the CoNS were cefoxitin resistant. History of vaginal infection, history of post-operative infection and antibiotic use acted as an important risk factor of AV incidence rate. The presence of AV worsened pregnancy outcomes, by increasing the incidence of preterm birth, the premature rupture of membranes, miscarriage, neonatal jaundice, and neonatal infection. CONCLUSION: Conclusions: Aerobic Vaginitis after gynecological surgeries in Ukraine is a common medical problem in women that is associated with significant morbidity, adverse pregnancy outcome, and hence frequent medical visits.

Mechanism of Yixishu lotion in the treatment of vaginitis based on network pharmacology combined with experimental validation: an experimental research study.

Objective: Yixishu lotion (YXSL) originates from the summary of traditional Chinese medicine clinical experience and constantly improves in practice in clinical validation of the exact efficacy of traditional Chinese medicine prescription. To explore the mechanism of YXSL in treating vaginitis and the potential mechanisms based on network pharmacology and experimental verification. Methods: The active components and drug-related targets of YXSL were retrieved from the TCMSP (Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform) database, and the target was predicted by the UniProt database. Searching for genes related to 'vaginitis' disease in the GeneCards database, a total of 2581 drug targets were obtained. The interaction between proteins (PPI - protein-protein interaction) relationship was obtained by STRING database and visualized by Cytoscape software. Finally, the 'Bioconductor' installation package in R software was used to analyze the GO (Gene Ontology) and KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways of the target. Results: In this study, by the method of network pharmacology, the key active components of YXSL were flavonoids such as quercetin, apigenin, kaempferol, luteolin, ß-sitosterol; the main core proteins included MAPK14, TP53, FGF2, ESR1, MAPK3, MAPK1, VEGFA, JUN, IL-6, and the KEGG pathway was mainly involved in MAPK pathway, Th17 pathway, Malaria, TNF pathway, and other signaling pathways. Animal experiments showed that the clinical symptoms and vaginal tissue lesions of the YXSL group and the fluconazole group were improved, and the levels of TNF-α (tumor necrosis factor alpha), IL-6 (interleukin-6), MDA (malondialdehyde), SOD (superoxide dismutase), IL-4, and IFN-γ (interferon-γ) in vaginal tissue and serum were better than the model group. Conclusion: YXSL may achieve its therapeutic effect on vaginitis by reducing the inflammatory response, improving oxidative stress response, and improving body immunity, and it provides a theoretical basis for further research on its pharmacodynamic material basis and mechanism of action.

Vaginosis citolítica: actualización diagnóstica y terapéutica / Cytolytic vaginosis: diagnostic and therapeutic update

El objetivo es conocer el abordaje diagnóstico y terapéutico de la vaginosis citolítica. Para ello se hizo una búsqueda sistemática de la literatura médica mediante las bases de datos: PubMed, Central, etc. Se limitó a ensayos clínicos aleatorizados, metaanálisis y revisiones bibliográficas, con disponibilidad del texto completo para evaluarlos en su totalidad e incluirlos en la revisión; publicados entre 1980 y 2021. Se incluyeron 27 publicaciones. La vaginosis citolítica es un trastorno infradiagnosticado. En mujeres con síntomas y signos de candidiasis vulvovaginal, que no responden a la terapia, se debe considerar la probabilidad de estar en presencia de una vaginosis citolítica. El tratamiento obliga a elevar el pH vaginal a valores básicos y a disminuir el número excesivo de Lactobacillus, resultando de utilidad las duchas vaginales con bicarbonato de sodio y/o un tratamiento con antibióticos derivados de la penicilina junto a un inhibidor de ß-lactamasas o doxiciclina en las pacientes alérgicas a la penicilina. Finalmente, se concluye que la vaginosis citolítica es una afección común, frecuentemente se diagnostica de forma errónea porque se confunde con la candidiasis vulvovaginal; se caracteriza por producir un cuadro clínico similar. El tratamiento se enfoca en disminuir el número de Lactobacillus y la elevación del pH vaginal.

The objective is to know the diagnostic and therapeutic approach of cytolytic vaginosis. A systematic search of the medical literature was carried out using the following databases: Medline via PubMed, Central, and Cochrane Database of Systematic Reviews, among others. The search was limited to randomized clinical trials, meta-analyses, and literature reviews that had the full text available for full evaluation and inclusion in the review; published between 1980 and 2021. Twenty-seven publications were included. Cytolytic vaginosis is a frequently underdiagnosed disorder, which mimics Candida vaginitis. In women with symptoms and signs of vulvovaginal candidiasis who do not respond to antifungal therapy, the possibility of cytolytic vaginosis should be considered. The treatment of this condition requires raising the vaginal pH to basic values and reducing the excessive number of Lactobacillus, resulting in useful vaginal douches with sodium bicarbonate and/or treatment with antibiotics derived from penicillin together with a ß-lactamases inhibitor or doxycycline in patients allergic to penicillin. Finally, we conclude that cytolytic vaginosis is a common condition, frequently misdiagnosed because it is confused with vulvovaginal candidiasis, since it is characterized by producing a similar clinical picture. Treatment focuses on reducing the number of Lactobacillus and raising vaginal pH.

Bacterial vaginosis, vulvovaginal candidiasis, trichomonal vaginitis and aerobic vaginitis in women from Egypt.

Introduction: Infectious vaginitis is prevalent in developing countries. Most of the females suffer from vaginal infections at least once per lifetime. Due to limited resources, many infections are misdiagnosed or undiagnosed. Good diagnosis of these infections is critically important and will definitely help to guide treatment and prevent recurrence. Methods: A total of 1080 vaginal swabs were collected from symptomatic females. Nugent's score and Amsel's criteria were applied to diagnose bacterial vaginosis (BV). A rapid test was used to identify Gardnerella vaginalis. Trichomonal vaginitis (TV) was diagnosed through microscopic examination. Vulvovaginal candidiasis (VVC) was also identified microscopically and using conventional culture. Finally, aerobic vaginitis (AV) was detected using Donder's scale combined with conventional culture and biochemical tests. Results: There was no statistically significant association between age and type of vaginal infection (p=0.130). Vulvovaginal inflammation, itching and redness were significantly associated with VVC (p≤0.012). BV was detected as single infection in 43.8%, followed by VVC 24.2%. On the contrary, AV and TV were scarcely detected among the participants; 4.9% and 0.5% respectively. Mixed infections between BV and VVC were noted in 26.6%. Conclusions: BV showed the highest prevalence followed by VVC. Mixed infections between BV and VVC were evidently noted, therefore good reliable diagnosis using cost-effective methods is crucial for proper treatment. Aerobic vaginitis showed low prevalence and most of the Streptococcus spp. were isolated from pregnant females. The low prevalence of Trichomonas vaginalis may be due to the dependance on conventional methods for diagnosis, and thus more advanced diagnostic tools are required.
