RESUMEN

BACKGROUND: Dyspareunia affects approximately half of postpartum women and is attributed to multiple factors. Despite its high prevalence and resultant negative effects, data are lacking regarding the causes and different pain components, the usefulness of recommended treatments, and the prognosis. AIM: To evaluate causes of postpartum dyspareunia, targeted treatment modalities, and their effectiveness. METHODS: A retrospective observational study was conducted of women diagnosed with postpartum dyspareunia between September 2008 and January 2017 at a single designated vulvovaginal disorder clinic. The inclusion criterion was complaint of painful intercourse commencing postdelivery. The cohort was divided into 4 groups based on the causes of dyspareunia: muscle hypertonicity, scar tenderness, vestibular tenderness, and atrophy. OUTCOMES: The following were assessed for each group: patient background demographics, clinical and obstetric data, physical findings, recommended therapy, adherence to the suggested treatment, level of improvement at follow-up visits, and length of time until maximal improvement. RESULTS: A hundred women met the inclusion criterion; the majority (n = 60) presented with >1 causative factor. The most common finding was vestibular tenderness (n = 78, 78%), which was significantly associated with atrophy (adjusted odds ratio [aOR], 15.08; 95% CI, 2.45-93.35), contraceptive usage (aOR, 4.76; 95% CI, 1.07-21.39), and primiparity (aOR, 4.89; 95% CI, 1.01-23.88). Episiotomy was the only risk factor for scar tenderness (aOR, 5.43; 95% CI, 1.20-24.53), while the existence of a spontaneous perineal tear was not. No specific correlation was found with pelvic floor muscle hypertonicity. Targeted treatment resulted in significant improvement in most patients. CLINICAL IMPLICATIONS: A targeted diagnostic and treatment approach for postpartum dyspareunia is effective and can be beneficial for caregivers treating postpartum women. STRENGTHS AND LIMITATIONS: A uniform and consistent protocol for patient selection and management is a major strength, which magnifies the clinical implication of our findings. The retrospective nature of the study is the primary limitation. CONCLUSION: Postpartum dyspareunia is a common problem; however, many women refrain from discussing it with their providers. Therefore, it is important to assess this condition with all women during the postpartum visit as targeted diagnosis and treatment can significantly improve outcomes.

RESUMEN

OBJECTIVE: This series of articles, titled The Vaginal Microbiome (VMB), written on behalf of the International Society for the Study of Vulvovaginal Disease, aims to summarize the recent findings and understanding of the vaginal bacterial microbiota, mainly regarding areas relevant to clinicians specializing in vulvovaginal disorders. MATERIALS AND METHODS: A search of PubMed database was performed, using the search terms "vaginal microbiome" with "dysbiosis," "bacterial vaginosis," "cytolytic vaginosis," "desquamative inflammatory vaginitis," and "aerobic vaginitis." Full article texts were reviewed. Reference lists were screened for additional articles. RESULTS: The second article in this series focuses on vaginal dysbiotic conditions. Dysbiosis is a term describing imbalances in bacterial communities. Given that lactobacillus-dominated microbiota are thought to be the most optimal, vaginal dysbiosis is usually considered as lactobacilli-depleted VMB. Bacterial vaginosis (BV), the most common vaginal dysbiotic condition, is a polymicrobial disorder, considered the leading cause for vaginal discharge in women worldwide. In addition, we review the VMB in other vaginal conditions associated with lactobacilli depletion: desquamative inflammatory vaginitis and aerobic vaginitis. We also discuss the controversial diagnosis of cytolytic vaginosis, related with lactobacilli overgrowth. CONCLUSIONS: Bacterial vaginosis displays complex microbiology. The heterogeneity and diversity within the genus Gardnerella may impact the progression of BV. Bacterial biofilms may contribute to the etiology and persistence of BV, and various bacteria may affect its clinical presentation and pathogenicity. Lack of lactobacilli is not always accompanied by an overgrowth of anaerobes.

RESUMEN

OBJECTIVE: This series of articles, titled The Vaginal Microbiome, written on behalf of the International Society for the Study of Vulvovaginal Disease, aims to summarize the current findings and understanding of the vaginal bacterial microbiota, mainly regarding areas relevant to clinicians specializing in vulvovaginal disorders. MATERIALS AND METHODS: A database search of PubMed was performed, using the search terms "vaginal microbiome" (VMB) with "research," "normal," "neonate," "puberty," "adolescent," "menopause," and "ethnicities," as well as "human microbiome project." Full article texts were reviewed. Reference lists were screened for additional articles. RESULTS: In the last 2 decades, many studies applying molecular techniques were performed, intending to characterize the vaginal microbiota. These studies advanced our understanding of how vaginal health is defined. The first article in this series focuses on the advancement of VMB research, technical definitions, the definition of "normal" VMB, and the dynamics of VMB throughout women's lives. CONCLUSIONS: Understanding how microorganisms inhabiting the vagina interact with each other and with the host is important for a more complete understanding of vaginal health. The clinical application of microbial community sequencing is in its beginning, and its interpretation regarding practical clinical aspects is yet to be determined.

RESUMEN

OBJECTIVE: This series of articles, titled The Vaginal Microbiome (VMB), written on behalf of the International Society for the Study of Vulvovaginal Disease, aims to summarize the recent findings and understanding of the vaginal bacterial microbiota, mainly regarding areas relevant to clinicians specializing in vulvovaginal disorders. MATERIALS AND METHODS: A search of PubMed database was performed, using the search terms "vaginal microbiome" with "reproduction," "infertility," "fertility," "miscarriages," "pregnancy" "cervical cancer," "endometrial cancer," and "ovarian cancer." Full article texts were reviewed. Reference lists were screened for additional articles. RESULTS: The fourth article of this series focuses on 2 distinct areas: the role of VMB in various aspects of human reproduction and, in sharp contrast, the association between the VMB and gynecologic malignancies. Several of the negative pregnancy outcomes have been associated with an altered VMB. Dysbiosis is remarkably linked with poor pregnancy outcomes from preconception to delivery. The associations between the microbiome and gynecologic cancers are described. CONCLUSIONS: The development of the microbiome research, enabled by molecular-based techniques, has dramatically increased the detection of microorganisms and the understanding of bacterial communities that are relevant to maternal-fetal medicine in health and disease, as well as in gynecological malignancies. Proving causation in cancer is difficult because of the complex interactive nature of potential causative factors. Certain elements of the microbiota have been shown to provoke inflammatory reactions, whereas others produce anti-inflammatory reactions; this balance might be impaired with a change in microbial variety.

RESUMEN

OBJECTIVE: This series of articles, titled The Vaginal Microbiome (VMB), written on behalf of the International Society for the Study of Vulvovaginal Disease, aims to summarize the recent findings and understanding of the vaginal bacterial microbiota, mainly regarding areas relevant to clinicians specializing in vulvovaginal disorders. MATERIALS AND METHODS: A search of PubMed database was performed, using the search terms "vaginal microbiome" with "treatment," "diagnosis," and "research." Full article texts were reviewed. Reference lists were screened for additional articles. RESULTS: The currently available approaches for treating vaginitis or attempting to modulate the VMB are often insufficient. It has traditionally relied on the use of antibiotics, antiseptics, and antifungals. The fifth and last article of this series discusses the new and/or alternative therapeutic modalities. It addresses the role of probiotics, prebiotics and symbiotics, activated charcoal, biofilm disrupting agents, acidifying agents, phage therapy, and the concept of vaginal microbiome transplant. The challenges facing the research of VMB, including the clinical impact of microbiome manipulation, classification, and new diagnostic approaches are discussed. CONCLUSIONS: Microbiome research has grown dramatically in recent years, motivated by innovations in technology and decrease in analysis costs. This research has yielded huge insight into the nature of microbial communities, their interactions, and effects with their hosts and other microbes. Further understanding of the bacterial, fungal, phage, and viral microbiomes in combination with host genetics, immunologic status, and environmental factors is needed to better understand and provide personalized medical diagnostics and interventions to improve women's health.

RESUMEN

OBJECTIVE: This series of articles, titled The Vaginal Microbiome (VMB), written on behalf of the International Society for the Study of Vulvovaginal Disease, aims to summarize the recent findings and understanding of the vaginal bacterial microbiota, mainly regarding areas relevant to clinicians specializing in vulvovaginal disorders. MATERIALS AND METHODS: A search of PubMed database was performed, using the search terms "vaginal microbiome" with "Candida," "vaginitis," "urinary microbiome," "recurrent urinary tract infections," "sexually transmitted infections," "human immunodeficiency virus," "human papillomavirus," "nonspecific vaginitis," "vulvodynia," and "vulvovaginal symptoms." Full article texts were reviewed. Reference lists were screened for additional articles. The third article in this series describes VMB in various urogenital disorders. RESULTS: Variable patterns of the VMB are found in patients with vulvovaginal candidiasis, challenging the idea of a protective role of lactobacilli. Highly similar strains of health-associated commensal bacteria are shared in both the bladder and vagina of the same individual and may provide protection against urinary tract infections. Dysbiotic VMB increases the risk of urinary tract infection. Loss of vaginal lactic acid-producing bacteria combined with elevated pH, increase the risk for sexually transmitted infections, although the exact protective mechanisms of the VMB against sexually transmitted infections are still unknown. CONCLUSIONS: The VMB may constitute a biological barrier to pathogenic microorganisms. When the predominance of lactobacilli community is disrupted, there is an increased risk for the acquisition of various vaginal pathogents. Longitudinal studies are needed to describe the association between the host, bacterial, and fungal components of the VMB.

RESUMEN

OBJECTIVE: Breastfeeding-related hypoestrogenic state has been reported as a possible risk factor for postpartum dyspareunia. This study aimed to evaluate the prevalence and characteristics of postpartum vulvovaginal atrophy according to 3 different diagnostic methods and to estimate its association with postpartum dyspareunia and daily vulvovaginal symptoms. METHODS: This is a prospective cohort study of puerperal women attending a routine postpartum checkup. Participants completed a questionnaire and underwent a gynecological examination. Atrophy was diagnosed separately according to gynecologist impression, vaginal pH measurement (≥5.1), and cytologic vaginal maturation index. Patients were followed up with a telephone survey 2-3 months later, inquiring about symptoms possibly associated with atrophy. RESULTS: Of 117 participants, vaginal atrophy was diagnosed in 48% by gynecological examination, 62% by a pH level of 5.1 or greater, and 40.2% had cytological atrophy. Of the 35.9% of women who had resumed sexual intercourse (42/117), 69% reported dyspareunia. No significant association was found between dyspareunia and atrophy parameters. There was no difference in the rates of dyspareunia among women who were exclusively breastfeeding (21/27 = 78%), partially breastfeeding (4/7 = 57%), or not breastfeeding (4/8, 50%). Atrophy was more common in breastfeeding women according to the 3 criteria (gynecological examination: 57.6% vs 16.7%, p = .006; pH: 70% vs 22%, p < .001; vaginal maturation index: 51.1% vs 0%, p < .001). Of the 117 participants, 47% reported daily vulvovaginal symptoms. Those with daily symptoms reported more dyspareunia as compared with those without daily symptoms (85% vs 52%, p = .025). CONCLUSIONS: A high prevalence of atrophy was observed in puerperal women in association with breastfeeding. There was no significant association between atrophy and dyspareunia or daily vulvovaginal symptoms.

RESUMEN

BACKGROUND: Low-level laser therapy (LLLT) is an emerging medical technology in which non-thermal laser irradiation is applied to treat pain. Because LLLT has been found effective in treating various pain syndromes without known side effects, we conducted a study evaluating the effect of LLLT on provoked vestibulodynia (PVD), a complex sexual pain disorder characterized by pain confined to the vulvar vestibule in response to contact or pressure. AIM: To investigate the effectiveness of LLLT for PVD in a randomized, placebo-controlled, double-blinded trial. METHODS: Patients with PVD were randomly assigned to receive treatment with LLLT or sham treatment. Patients were treated twice weekly for 6 weeks, for a total of 12 LLLT or placebo sessions. Patients who showed improvement after LLLT were followed for 1 year by clinical pain report and Q-tip examination. OUTCOMES: Change in pain scores obtained in response to the Q-tip test, clinical pain report, visual analog scale score, pain with tampon insertion, daily pain intensity, intercourse pain intensity, frequency of intercourse, and a battery of quality-of-life measures. RESULTS: Thirty-four patients with PVD participated, 18 received LLLT and 16 received placebo. In the clinical pain report at study completion, 14 of 18 patients (78%) receiving LLLT reported improvement compared with 7 of 16 (44%) in the placebo group (P = .042). This effect was not apparent in other outcome measurements. None of the patients reported side effects during the study. At 1-year follow-up, eight patients (57%) reported lasting improvement. CLINICAL IMPLICATIONS: Larger studies with various treatment protocols are needed to define which patients can benefit from LLLT therapy. STRENGTHS AND LIMITATIONS: Strengths include a placebo-controlled, double-blinded design, measurement of a large number of multidimensional end points, and a follow-up period of 1 year. Limitations include the small number of patients recruited, no improvement in measurable parameters, a high improvement rate in the placebo group, the absence of use of validated questionnaires, and the lack of evaluation of psychological and interpersonal factors that might have influenced the results. CONCLUSIONS: Given the results of this pilot study, LLLT cannot currently be recommended as a treatment for PVD. Further studies with a larger population, various treatment protocols, and evaluation of LLLT in different subgroups of PVD are needed to define which patients can benefit from this therapy.

RESUMEN

The focus of this article, the fourth in the series, Standards for Clinical Trials in Male and Female Sexual Dysfunction, is on aspects of clinical trial design and measurement that are specific to clinical trials for treatments of female sexual dysfunction. Challenges in this area include the limited extent of treatment development and clinical trial research across the spectrum of female sexual dysfunctions, changing regulatory considerations, changing diagnostic criteria for female sexual dysfunction, and the need to articulate assessment procedures to these changes. Discussion focuses on approaches to addressing these challenges in clinical trials in female sexual dysfunction.

RESUMEN

Gynecologist and plastic surgeons pioneered the application of lasers in medicine and surgery almost 5 decades ago, initially used to treat cervical and vaginal pathologies. Ever since, energy-based devices have been deployed to treat pelvic pathologies and improve fertility. Recent technological developments triggered an unprecedented wave of publications, assessing the efficacy of fractional laser, and radiofrequency on the vaginal wall in reversing natural aging processes. Studies have shown that a certain degree of thermal energy deposited on the vaginal wall stimulates proliferation of the glycogen-enriched epithelium, neovascularization, and collagen formation in the lamina propria, and improves natural lubrication and control of urination. This review aimed to review such data and to guide future research. A unique assembly of experts from around the globe, compiled and edited this manuscript based on a thorough literature review and personal experience. Lasers Surg.

RESUMEN

This series of articles outlines standards for clinical trials of treatments for male and female sexual dysfunctions, with a focus on research design and patient-reported outcome assessment. These articles consist of revision, updating, and integration of articles on standards for clinical trials in male and female sexual dysfunction from the 2010 International Consultation on Sexual Medicine developed by the authors as part of the 2015 International Consultation on Sexual Medicine. We are guided in this effort by several principles. In contrast to previous versions of these guidelines, we merge discussion of standards for clinical trials in male and female sexual dysfunction in an integrated approach that emphasizes the common foundational practices that underlie clinical trials in the two settings. We present a common expected standard for clinical trial design in male and female sexual dysfunction, a common rationale for the design of phase I to IV clinical trials, and common considerations for selection of study population and study duration in male and female sexual dysfunction. We present a focused discussion of fundamental principles in patient- (and partner-) reported outcome assessment and complete this series of articles with specific discussions of selected aspects of clinical trials that are unique to male and to female sexual dysfunction. Our consideration of standards for clinical trials in male and female sexual dysfunction attempts to embody sensitivity to existing and new regulatory guidance and to address implications of the evolution of the diagnosis of sexual dysfunction that have been brought forward in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. The first article in this series focuses on phase I to phase IV clinical trial design considerations. Subsequent articles in this series focus on the measurement of patient-reported outcomes, unique aspects of clinical trial design for men, and unique aspects of clinical trial design for women.

RESUMEN

The second article in this series, Standards for Clinical Trials in Male and Female Sexual Dysfunction, focuses on measurement of patient-reported outcomes (PROs). Together with the design of appropriate phase I to phase IV clinical trials, the development, validation, choice, and implementation of valid PRO measurements-the focus of the present article-form the foundation of research on treatments for male and female sexual dysfunctions. PRO measurements are assessments of any aspect of a patient's health status that come directly from the patient (ie, without the interpretation of the patient's responses by a physician or anyone else). PROs are essential for assessing male and female sexual dysfunction and treatment response, including symptom frequency and severity, personal distress, satisfaction, and other measurements of sexual and general health-related quality of life. Although there are some relatively objective measurements of sexual dysfunction (ie, intravaginal ejaculatory latency time, frequency of sexual activity, etc), these measurements do not comprehensively assess the occurrence and extent of sexual dysfunction or treatment on the patient's symptoms, functioning, and well-being. Data generated by a PRO instrument can provide evidence of a treatment benefit from the patient's perspective.

RESUMEN

Vulvovaginal atrophy is a common condition associated with decreased estrogenization of the vaginal tissue. Symptoms include vaginal dryness, irritation, itching, soreness, burning, dyspareunia, discharge, urinary frequency, and urgency. It can occur at any time in a woman's life cycle, although more commonly in the postmenopausal phase, during which the prevalence is approximately 50%. Despite the high prevalence and the substantial effect on quality of life, vulvovaginal atrophy often remains underreported and undertreated. This article aims to review the physiology, clinical presentation, assessment, and current recommendations for treatment, including aspects of effectiveness and safety of local vaginal estrogen therapies.

RESUMEN

BACKGROUND: Accurate detection of graft-versus-host disease (GVHD) is a major challenge in the management of patients undergoing hematopoietic stem cell transplantation (HCT). Here, we demonstrated the use of circulating cell-free DNA (cfDNA) for detection of tissue turnover and chronic GVHD (cGVHD) in specific organs. METHODS: We established a cocktail of tissue-specific DNA methylation markers and used it to determine the concentration of cfDNA molecules derived from the liver, skin, lungs, colon, and specific immune cells in 101 patients undergoing HCT. RESULTS: Patients with active cGVHD showed elevated concentrations of cfDNA, as well as tissue-specific methylation markers that agreed with clinical scores. Strikingly, transplanted patients with no clinical symptoms had abnormally high levels of tissue-specific markers, suggesting hidden tissue turnover even in the absence of evident clinical pathology. An integrative model taking into account total cfDNA concentration, monocyte/macrophage cfDNA levels and alanine transaminase was able to correctly identify GVHD with a specificity of 86% and precision of 89% (AUC of 0.8). CONCLUSION: cfDNA markers can be used for the detection of cGVHD, opening a window into underlying tissue dynamics in patients that receive allogeneic stem cell transplants. FUNDING: This work was supported by grants from the Ernest and Bonnie Beutler Research Program of Excellence in Genomic Medicine, The Israel Science Foundation, the Waldholtz/Pakula family, the Robert M. and Marilyn Sternberg Family Charitable Foundation and the Helmsley Charitable Trust (to YD).

RESUMEN

Vaginitis is a common gynecological problem, nevertheless, its clinical evaluation is often insufficient. This study evaluated the performance of an automated microscope for the diagnosis of vaginitis, by comparison of the investigated test results to a composite reference standard (CRS) of wet mount microscopy performed by a specialist in vulvovaginal disorders, and related laboratory tests. During this single-site cross-sectional prospective study, 226 women reporting vaginitis symptoms were recruited, of which 192 samples were found interpretable and were assessed by the automated microscopy system. Results showed sensitivity between 84.1% (95%CI: 73.67-90.86%) for Candida albicans and 90.9% (95%CI: 76.43-96.86%) for bacterial vaginosis and specificity between 65.9% (95%CI: 57.11-73.64%) for Candida albicans and 99.4% (95%CI: 96.89-99.90%) for cytolytic vaginosis. These findings demonstrate the marked potential of machine learning-based automated microscopy and an automated pH test of vaginal swabs as a basis for a computer-aided suggested diagnosis, for improving the first-line evaluation of five different types of infectious and non-infectious vaginal disorders (vaginal atrophy, bacterial vaginosis, Candida albicans vaginitis, cytolytic vaginosis, and aerobic vaginitis/desquamative inflammatory vaginitis). Using such a tool will hopefully lead to better treatment, decrease healthcare costs, and improve patients' quality of life.

RESUMEN

OBJECTIVE: This study aimed to examine differences in symptoms and diagnoses between women 50 years and younger and women older than 50 years who have chronic vulvovaginal complaints. METHODS: New patients of the Drexel University Vaginitis Center with chronic vulvovaginal complaints were eligible. Participants underwent a standardized medical evaluation and completed detailed questionnaires. Data were analyzed using the t test, χ test, and the Fisher exact test. RESULTS: Subjects were 469 women aged 18 to 79 years. Subjects 50 years and younger (group A) were more likely to complain of vaginal itching and were less likely to complain of burning, irritation, or soreness (p ≤ .05 for all). Subjects older than 50 years (group B) were more likely to be diagnosed with atrophic vaginitis (p = .000), desquamative inflammatory vaginitis (DIV; p = .001), lichen planus (LP; p = .000), and lichen sclerosus (p = .000). Diagnosis of LS, LP, or DIV was associated with increased likelihood of multiparity and decreased likelihood of a history of systemic estrogen use. CONCLUSIONS: Postmenopausal women are more likely than premenopausal women to be diagnosed with DIV, LP, or LS. Both childbirth and estrogen nonuse were associated with the occurrence of these latter 3 conditions.

RESUMEN

None of the currently available parameters allow for a direct and objective measurement of vaginal moisture. We used a calibrated filter paper strip as a measurement tool for the quantification of vaginal fluid, in a similar manner as the ophthalmic "Schirmer test" (used for eye moisture measurement). The study aimed to evaluate the validity of this new, objective tool, to measure vaginal moisture. We compared vaginal moisture measurements using the "modified Schirmer test" in symptomatic women with genitourinary syndrome of menopause to those of women without vaginal dryness. The mean "modified Schirmer test" measurement in the control group was 21.7 mm compared to 3.3 mm in the study group, yielding a statistically significant difference (p < 0.001). Strong correlations were found between "modified Schirmer test" measurements and pH (correlation coefficient −0.714), Vaginal Health Index [VHI (0.775)], and Visual Analogue Score (VAS) of dryness during intercourse (−0.821). Our findings suggest that the "modified Schirmer test" can be used as an objective measurement for the assessment of vaginal fluid level. This test may also prove useful for evaluation of non-hormonal treatments aimed to treat vaginal dryness.

The pathophysiology underlying painful intercourse is challenging due to variability in manifestations of vulvar pain hypersensitivity. This study aimed to address whether the anatomic location of vestibular-provoked pain is associated with specific, possible causes for insertional dyspareunia. Women (n = 113) were assessed for "anterior" and "posterior" provoked vestibular pain based on vestibular tenderness location evoked by a Q-tip test. Pain evoked during vaginal intercourse, pain evoked by deep muscle palpation, and the severity of pelvic floor muscles hypertonicity were assessed. The role of potential confounders (vestibular atrophy, umbilical pain hypersensitivity, hyper-tonus of pelvic floor muscles and presence of a constricting hymenal-ring) was analyzed to define whether distinctive subgroups exist. Q-tip stimulation provoked posterior vestibular tenderness in all participants (6.20 ± 1.9). However, 41 patients also demonstrated anterior vestibular pain hypersensitivity (5.24 ± 1.5). This group (circumferential vestibular tenderness), presented with either vestibular atrophy associated with hormonal contraception use (n = 21), or augmented tactile umbilical-hypersensitivity (n = 20). The posterior-only vestibular tenderness group included either women with a constricting hymenal-ring (n = 37) or with pelvic floor hypertonicity (n = 35). Interestingly, pain evoked during intercourse did not differ between groups. Linear regression analyses revealed augmented coital pain experience, umbilical-hypersensitivity and vestibular atrophy predicted enhanced pain hypersensitivity evoked at the anterior, but not at the posterior vestibule (R = 0.497, p < 0.001). Distinguishing tactile hypersensitivity in anterior and posterior vestibule and recognition of additional nociceptive markers can lead to clinical subgrouping.

RESUMEN

Vulvovaginal Graft-versus-host disease (VV-GVHD) is an underdiagnosed complication of hematopoietic stem cell transplantation (HSCT). The severity of the disease varies greatly, ranging from minor discomfort to severe, irreversible anatomic changes. This study sought to assess the long-term course of VV-GVHD. A retrospective analysis was conducted of 64 women who underwent HSCT and were followed over 9 years in a designated vulvovaginal clinic. VV-GVHD was detected in 56% of transplanted women. Adherence with follow-up correlated with diagnosis of VV-GVHD (p < 0.001) and with sexual activity (p = 0.023). Most of the women with VV-GVHD were symptomatic; however, 22% were asymptomatic upon diagnosis. Women were treated with topical steroids, topical estrogen, vaginal dilators, and vaginal silicone rings. Vaginal silicone rings were associated with higher patient adherence and better results. VV-GVHD is a common complication of HSCT and can adversely impact patients' sexuality and quality of life. The disease pattern is chronic, necessitating long term follow-up and adherence with treatment. Vulvar anatomical changes occurred despite treatment; however, vaginal patency can be maintained by early diagnosis, constant surveillance, and early treatment, consequently allowing preservation of normal sexual function. Awareness of VV-GVHD must be raised in order to better serve female patients and facilitate early diagnosis and treatment.
