Review
Vaginal microbiome is mutually beneficial to the host and has a significant impact on health and disease. species, including , are part of the mucosal flora of most healthy women. Under suitable conditions, they can live in the vulvovaginal mucosa, resulting in symptomatic vulvovaginal candidiasis (VVC). Based on the analysis of 16S ribosomal RNA gene sequences, great progress has been made in exploring the composition and structure of vaginal bacterial community. Moreover, researchers have conducted several studies on whether vaginal microbiome will change during VVC infection. In addition, it has been reported that vaginal colonization of probiotics in vaginal microorganisms, especially , can effectively reduce the risk of VVC and treat VVC. This review aims to summarize the changes of vaginal microflora during VVC infection, and further point out the possibility of using lactic acid bacteria as probiotics to treat VVC, so as to reduce the adverse consequences of VVC infection and reduce the expensive treatment cost.

Review
BACKGROUND
Vulvovaginal candidiasis (VVC) is a common cause of vulvovaginal itching and discharge. This article discusses the latest CDC STI Treatment Guidelines for VVC.
METHODS
A literature search of relevant topics was performed, and a team of experts was convened to discuss (1) diagnosis/testing modalities; treatment of (2) uncomplicated VVC , (3) complicated VVC, and (4) VVC caused by non-albicans yeast; (5) alternative treatment regimens; (6) susceptibility testing of yeast; Special Populations: (7) pregnancy and (8) HIV and VVC.
RESULTS
Yeast culture remains the gold standard for diagnoses. Newer molecular assays have been developed for the diagnosis of VVC and perform well. Azole antifungals remain the treatment of choice for uncomplicated VVC. Two new drugs, TOL-463 and recently FDA-approved ibrexafungerp, appeared promising in clinical trials. For recurrent VVC, oteseconazole, not yet commercially available, may represent a new option. For non-albicans yeast infections in symptomatic patients, boric acid appears useful. No evidence supports the use of alternative treatments, including probiotics. Fluconazole during pregnancy may be associated with spontaneous abortion and craniofacial and heart defects. In women with HIV infection, lower CD4+ T-cell counts are associated with increased rates of VVC, and VVC is associated with increased viral shedding. Treatment measures in women with HIV infection are identical to those women without HIV infection.
CONCLUSIONS
There has been significant new knowledge generated about VVC since the 2015 CDC Guidelines which have led to changing recommendations.

Review
Vaginal symptoms are one of the most common reasons women consult with physicians and can significantly impact quality of life. The differential diagnosis of vaginal discharge includes physiologic discharge, vaginitis, cervicitis, and pelvic inflammatory disease (PID). Vaginitis is inflammation of the vagina, most commonly caused by bacterial vaginosis (BV), vulvovaginal candidiasis, and trichomoniasis infections. Cervicitis is an inflammation of the cervix and typically caused by Chlamydia trachomatis and Neisseria gonorrhoeae. PID is infection of the female upper genital tract, involving the uterus, fallopian tubes, ovaries, and/or pelvic peritoneum and usually caused by Chlamydia trachomatis, Neisseria gonorrhoeae, and bacterial vaginosis-associated pathogens. A pelvic exam should be performed for any woman presenting with vaginal discharge to confirm the diagnosis and rule out an upper tract infection. BV and vulvovaginal candidal infections only require treatment if symptomatic and do not require partner therapy, whereas treatment and partner therapy is recommended for sexually transmitted illnesses, such as trichomoniasis, chlamydia and gonorrhea. Vaginitis may be uncomfortable, but rarely leads to serious long-term consequence, but pelvic inflammatory disease can lead to serious long-term sequelae, including increased risk for ectopic pregnancy, infertility, and chronic pelvic pain.

Review
The article raises important issues regarding the use of diet and probiotics in prevention and treatment of vaginitis. Vaginitis is defined as any condition with symptoms of abnormal vaginal discharge. The most common causes of vaginitis are vulvovaginal candidiasis (VVC), trichomoniasis and bacterial vaginosis (BV). Vaginitis has been linked to itching, burning, pain, discharge, irritation and also adverse reproductive and obstetric health outcomes. Moreover, microorganisms that build vaginal flora in the state of bacterial vaginosis are a source of cervicitis and endometritis (often in subclinical forms) and pelvic inflammatory disease (PID) The proper diet and probiotics consumption may influence the composition of the gut microbiota, improve gut integrity, and have an impact on maintaining and recovering the normal vaginal microbiota. Future studies and reviews investigating the role of diet and probiotics in changes to gut and vaginal microbiome need to focus on deciphering the mechanismus of host bacteria interaction in vulvovaginal health.

Review
Dermatologists commonly prescribe medications such as antibiotics and corticosteroids that can increase the risk for candidiasis. Though conventional antifungals are often effective against candidiasis, they are not without side effects and species of Candida are gaining resistance. Probiotics help treat conditions such as post-antibiotic diarrhea and infectious diarrhea, and thus have the potential to help with Candida infections, as well. For this reason, we provide an overview of therapies prescribed in dermatology that may increase the risk for candidiasis, and we review the literature on whether probiotics are useful in the treatment and prevention of oral and vulvovaginal candidiasis to help dermatologists treating the condition be better informed about their supplemental use with conventional antifungals.

Review
Vulvovaginal candidiasis (VVC) is a widespread vaginal infection primarily caused by VVC affects up to 75% of women of childbearing age once in their life, and up to 9% of women in different populations experience more than three episodes per year, which is defined as recurrent vulvovaginal candidiasis (RVVC). RVVC results in diminished quality of life as well as increased associated healthcare costs. For a long time, VVC has been considered the outcome of inadequate host defenses against colonization, as in the case of primary immunodeficiencies associated with persistent fungal infections and insufficient clearance. Intensive research in recent decades has led to a new hypothesis that points toward a local mucosal overreaction of the immune system rather than a defective host response to colonization. This review provides an overview of the current understanding of the host immune response in VVC pathogenesis and suggests that a tightly regulated fungus-host-microbiota interplay might exert a protective role against recurrent infections.

Review
The different Lactobacillus strains of probiotics have been applied to the treatment and prevention of bacterial vaginosis and vulvovaginal candidiasis. The experimental data demonstrated that it works well via reducing the number of harmful bacteria, maintaining the acidic microenvironment, inhibiting the immune response, and so on, to restore the vaginal microecology. However, the clinical data indicated that it is not sufficient to support the use of probiotics in the intervention of vulvovaginal candidiasis rather than bacterial vaginosis. Hunting for novel probiotic strains and uncovering the precise mechanism of probiotics, especially with the new concept gut-vagina axis, to maintain the homeostasis of vaginal microbiota should be a great challenge in the future.

Review
Approximately 70-75% of women will have vulvovaginal candidosis (VVC) at least once in their lifetime. In premenopausal, pregnant, asymptomatic and healthy women and women with acute VVC, Candida albicans is the predominant species. The diagnosis of VVC should be based on clinical symptoms and microscopic detection of pseudohyphae. Symptoms alone do not allow reliable differentiation of the causes of vaginitis. In recurrent or complicated cases, diagnostics should involve fungal culture with species identification. Serological determination of antibody titres has no role in VVC. Before the induction of therapy, VVC should always be medically confirmed. Acute VVC can be treated with local imidazoles, polyenes or ciclopirox olamine, using vaginal tablets, ovules or creams. Triazoles can also be prescribed orally, together with antifungal creams, for the treatment of the vulva. Commonly available antimycotics are generally well tolerated, and the different regimens show similarly good results. Antiseptics are potentially effective but act against the physiological vaginal flora. Neither a woman with asymptomatic colonisation nor an asymptomatic sexual partner should be treated. Women with chronic recurrent Candida albicans vulvovaginitis should undergo dose-reducing maintenance therapy with oral triazoles. Unnecessary antimycotic therapies should always be avoided, and non-albicans vaginitis should be treated with alternative antifungal agents. In the last 6 weeks of pregnancy, women should receive antifungal treatment to reduce the risk of vertical transmission, oral thrush and diaper dermatitis of the newborn. Local treatment is preferred during pregnancy.

Review
Recurrent vulvovaginal infections (RVVI) has not only become an epidemiological and clinical problem but also include large social and psychological consequences. Understanding the mechanisms of both commensalism and pathogenesis are necessary for the development of efficient diagnosis and treatment strategies for these enigmatic vaginal infections. Through this review, an attempt has been made to analyze vaginal microbiota (VMB) from scratch and to provide an update on its current understanding in relation to health and common RVVI i.e. bacterial vaginosis, vulvovaginal candidiaisis and Trichomoniasis, making the present review first of its kind. For this, potentially relevant studies were retrieved from data sources and critical analysis of the literature was made. Though, culture-independent methods have greatly unfolded the mystery regarding vaginal bacterial microbiome, there are only a few studies regarding the composition and diversity of vaginal mycobiome and different Trichomonas vaginalis strains. This scenario suggests a need of further studies based on comparative genomics of RVVI pathogens to improve our perceptive of RVVI pathogenesis that is still not clear (Fig. 5). Besides this, the review details the rationale for Lactobacilli dominance and changes that occur in healthy VMB throughout a women's life. Moreover, the list of possible agents continues to expand and new species recognised in both health and VVI are updated in this review. The review concludes with the controversies challenging the widely accepted dogma i.e. "VMB dominated with Lactobacilli is healthier than a diverse VMB". These controversies, over the past decade, have complicated the definition of vaginal health and vaginal infections with no definite conclusion. Thus, further studies on newly recognised microbial agents may reveal answers to these controversies. Conversely, VMB of women could be an answer but it is not enough to just look at the microbiology. We have to look at the woman itself, as VMB which is fine for one woman may be troublesome for others. These differences in women's response to the same VMB may be determined by a permutation of behavioural, cultural, genetic and various other anonymous factors, exploration of which may lead to proper definition of vaginal health and disease.

Review
Vulvovaginal candidiasis (VVC) is a common condition associated with discomfort in affected women. Due to the presence of different forms of the disease, diverse treatment regimens are developed; the newest ones include oteseconazole and ibrexafungerp. Here, we focus on the most up-to-date recommendations regarding VVC treatment, as well as novel treatment options. Topical and oral azoles are the drugs of choice in uncomplicated mycosis. The efficacy of probiotics and substances such as TOL-463 and chlorhexidine is indicated as satisfactory; however, there are no relevant guidelines. Although the majority of researchers agree that the treatment of non-albicans VVC should be long-lasting, the recommendations are inconsistent. Another clinical problem is the treatment of VVC with azole intolerance or resistance, for which literature proposes the use of several drugs including oteseconazole, ibrexafungerp, and voriconazole. The treatment schedules for recurrent VVC include mainly fluconazole; however, alternative options such as immunotherapeutic vaccine (NDV-3A) or designed antimicrobial peptides (dAMPs) were also described. We also focused on VVC affecting pregnant women, which is a substantial challenge in clinical practice, also due to the heterogeneous relevant guidelines. Thus far, few precise recommendations are available in the literature. Future studies should focus on atypical VVC forms to elucidate the inconsistent findings.
