Case-control study of vulvar vestibulitis risk associated with genital infections

Combined estrogen-progestin oral contraceptives and female sexuality: an updated review

INTRODUCTION

Sexual side effects of combined oral contraceptives (COCs) have not been fully understood, but increasing evidence prompts broader risk/benefit evaluation and merits inclusion in counseling on contraceptive options.

OBJECTIVES

The study sought to explore the impact of combined estrogens-progestin oral contraceptives on components of female sexuality, including sexual desire, anatomic genitourinary changes, lubrication, orgasm, provoked vestibulodynia, well-being, body image, partner preference, and relationship stability.

METHODS

A literature review was performed between April 2023 and January 2024 exploring the association between combined oral contraceptive pills and sexual health.

RESULTS

Although COCs decrease free testosterone, it is unclear if COCs affect sexual function, including desire. Antiandrogenic COCs do seem to have a negative effect on sexual arousal, lubrication, and orgasm. Provoked vestibulodynia may be related to early onset of COC use, low-estrogen pills, and antiandrogenic progestins. Emotional and sexual side effects are strong predictors of COC discontinuation. Longitudinal data indicate that using COCs when meeting and selecting a partner has implications on sexual satisfaction and relationship length. Analysis of data is complicated by various doses and forms of estrogen and progestin in COCs, which have changed over time.

CONCLUSION

Lack of randomized placebo-controlled studies and heterogenicity in study design hampers generalized statements about the effects of COCs on sexual function. Despite these challenges, consideration of sexual dysfunction when presenting and prescribing hormonal contraception is essential for informed consent, shared decision making, and ensuring reliable contraceptive choices.

The histopathological results of vestibulectomy specimens in localized provoked vulvodynia in Turkey

Introduction

Localized Provoked Vulvodynia (LPV) is a gynecological disease that is difficult to manage. Despite the wide spectrum of pathophysiological mechanisms and treatment modalities, there is limited success in the management of this disease. Surgical treatment is usually performed as the last resort. We aimed to investigate the histopathological results of 38 women with LPV who underwent surgical vestibulectomy.

Methods

of the 55 women that were diagnosed with LPV and underwent vulvar vestibulectomy, 38 patients with complete histopathological results were included in this retrospective study.

Results

in 14 patients, the pathological reports revealed Low-Grade Squamous Intraepithelial Lesions (LGSIL) (36.8%) whereas for 21 cases (55.2%), the findings were concordant with vestibulitis. The remaining three patients (7.8%) were diagnosed with lichen simplex chronicus.

Conclusion

the presence of LGSIL in the surgical specimens of LPV cases is noteworthy. In this group of patients, surgical excision may contribute to the prevention of progression into high-grade lesions. The relationship between Human Papilloma Virus (HPV) infections and LPV should be further investigated.

Exploring Hygienic Behaviors and Vulvodynia

OBJECTIVES

Vulvodynia is common and characterized by vulvar discomfort and pain. However, few studies have assessed hygienic practices in relation to onset. We investigated whether hygienic behaviors were associated with the onset of vulvodynia.

MATERIALS AND METHODS

We assessed a self-reported history of personal hygienic behaviors, including wearing tight-fitting clothing, vulva care and genital washing, pubic hair removal, douching, and powdering, a year before first reported onset of vulvar pain among 213 clinically confirmed cases and a similar time period among 221 general population controls.

RESULTS

Compared with women who reported never wearing tight-fitting jeans or pants, women wearing tight-fitting jeans or pants 4 or more times per week had twice the odds of vulvodynia (95% CI = 1.14-3.95). Relative to controls, women with vulvodynia were substantially less likely to report use of soaps and gels to cleanse the vulva (95% CI = 0.17-0.63). Among women who chose to remove pubic hair, those who removed pubic hair from the mons pubis compared with bikini-area only hair removal, were 74% more likely to have vulvodynia (95% CI = 1.05-2.89). Finally, compared with women who reported bikini-area only hair removal less than monthly, those who removed hair from the mons pubis weekly or more were nearly 2 times more likely to be vulvodynia cases (95% CI = 0.83-3.49).

CONCLUSIONS

Wearing tight-fitting jeans or pants and removing hair from the mons pubis area were associated with increased odds of vulvodynia. Research on how hygienic practices could influence vulvar pain in larger and more temporally addressed populations is warranted.

Recurrent Yeast Infections and Vulvodynia: Can We Believe Associations Based on Self-Reported Data?

OBJECTIVE

We determined whether self-reported new or recurrent yeast infections were a risk factor for and/or consequence of vulvodynia and then determined the extent to which various levels of misclassification of self-reported yeast infections influenced these results.

MATERIALS AND METHODS

In this case-control study we retrospectively assessed self-reported new and recurrent yeast infections prior and subsequent to first vulvar pain onset among 216 clinically confirmed cases and during a similar time period for 224 general population controls.

RESULTS

A history of >10 yeast infections before vulvodynia onset was strongly but imprecisely associated with currently diagnosed vulvodynia after adjustment for age, age at first intercourse, and history of urinary tract infections [adjusted odds ratio = 5.5, 95% confidence interval (CI) 1.7-17.8]. Likewise, a history of vulvodynia was associated with a twofold risk of subsequent new or recurrent onset of yeast infections after adjustment for age, age at first intercourse, and history of yeast infections before vulvodynia onset (comparable time period among controls, 95% CI 1.5-2.9). Bias analyses showed that our observed associations were an underestimation of the true association when nondifferential misclassification of self-reported yeast infections and certain differential misclassification scenarios were present. However, if women with vulvodynia more frequently misreported having them when they truly did not, our observed associations were an overestimate of the truth.

CONCLUSIONS

There appears to be a positive relationship between yeast infections preceding and following the diagnosis of vulvodynia, but this relationship varies from strong to nonexistent depending on the relative accuracy of the recalled diagnosis of yeast infections among cases and controls. To better understand the bidirectional associations between yeast infections and vulvodynia, future validation studies are needed to determine the extent to which misclassification of self-reported yeast infections differs between women with and without vulvodynia.

Chronic Pelvic and Vulvar Pain in Women

Peripheral generators and the central nervous system have a role in the production of visceral and somatic hypersensivities and hyperalgesias.More generalised symptoms often exist and efferent activity from the CNS may also be responsible for abnormal visceral and muscular function.It is important to dissect out the symptoms and as well as treating peripheral generators to consider interventions of the central mechanisms aimed at the cognitive behavioural aspects of the patients' condition.

Activation of vestibule-associated lymphoid tissue in localized provoked vulvodynia

OBJECTIVE

Localized provoked vulvodynia (LPV) may have inflammatory etiology. We wanted to find out whether the cell-mediated immune system becomes activated in the vestibular mucosa in LPV.

STUDY DESIGN

This was a controlled cross-sectional study. Vestibular mucosal specimens were obtained from 27 patients with severe LPV and 15 controls. Detailed clinical history of the patients was obtained. For immunohistochemistry, antibodies against CD3 (T cells), CD20 (B cells), IgA (mucosal plasma cells), CD163 (dendritic cells [DCs]), CD68 (macrophages), and CD117 (mast cells) were employed. Mann-Whitney U test and χ(2) test were used for statistical analyses.

RESULTS

More B lymphocytes and mature mucosal IgA-plasma cells were found in patients than in controls (P < .001 and P < .001, respectively). In LPV samples, B and T cells were arranged into germinal centers representing local immune activation. Germinal centers were not seen in controls. Antigen-presenting DCs and macrophages were found both in patients and controls with similar densities. DCs were found to extend their dendrites into the luminal space through an intact epithelium. Similar amounts of mast cells were found evenly scattered throughout the stroma of vestibular mucosa of both patients and controls.

CONCLUSION

We demonstrate here local organized vestibule-associated lymphoid tissue analogous to mucosa-associated lymphoid tissue. Vestibule-associated lymphoid tissue may emerge as a response to local infection or inflammation in LPV.

CD4-positive T-cell recruitment in primary-provoked localized vulvodynia: potential insights into disease triggers

OBJECTIVE

To better understand the potential disease triggers of neurogenic inflammation in provoked localized vulvodynia (PLV), our objective was to determine whether the types of infiltrating lymphocytes were different in vestibular biopsies from women with primary PLV, secondary PLV, and unaffected controls.

METHODS

Secondary retrospective analysis of archived vestibular biopsies from a series of adult premenopausal women with primary PLV (n = 10), secondary PLV (n = 10), and unaffected controls (n = 4) was performed. All study patients had severe entry dyspareunia for more than 1 year. Subjects were excluded if pregnant, or they had a known infection, or history of generalized vulvodynia. Biopsies were performed during the midfollicular phase. Lymphocyte subtypes were highlighted in histologic sections using antibodies against CD3, CD4, and CD8 and scored as the mean number of T-cell subtypes per high-power field. Flow cytometry was also used to test fresh biopsies from a de novo prospective series of primary PLV (n = 4) and unaffected controls (n = 2).

RESULTS

Unaffected control biopsies showed more CD8-positive than CD4-positive T cells, similar to previous reports of the gynecologic tract. In contrast, biopsies from women with primary PLV showed significantly more CD4-positive T cells than those from women with secondary PLV and unaffected controls (p = .003). This observation was further supported by flow cytometry.

CONCLUSIONS

CD4-positive T cells are more numerous in vestibular biopsies from premenopausal women with primary PLV. This may be important because subtypes of CD4-positive T cells are specifically recruited by infectious, allergic, or autoimmune triggers. Future studies distinguishing these subtypes may lead to new insights into this common disease.

The recurrent pain and sexual sequelae of provoked vestibulodynia: a perpetuating cycle

INTRODUCTION

Optimal management of provoked vestibulodynia (PVD), thought to be the most common form of chronic dyspareunia, is unclear.

AIM

To integrate recent brain data on chronic pain circuitry with stress-induced neuroendocrine mechanisms in the skin and the stress burden (allostatic load) of women with PVD; to also clarify the typical chronicity and negative sexual sequelae associated with PVD; and then review modulation of pain circuitry by cognitive therapy and mindfulness practice and apply to PVD management. Methods.  Review of scientific publications in the areas of sexual medicine, pain, brain imaging, gynecology, stress response, mindfulness, and cognitive behavioral therapy (CBT).

MAIN OUTCOME MEASURES

(i) A model of PVD to reflect its etiology, typical chronicity, and the detrimental effects on sexual function; (ii) Interventions of sexual rehabilitation based on principles underlying changes associated with CBT and mindfulness practice.

RESULTS

A model emerges which reflects how stress-induced changes of pain amplification (central sensitization), characteristic of chronic pain conditions, may impair sexual response in addition to sexual dysfunction that arises from conscious pain avoidance and/or fear-related inattention to sexual cues. Stress from low self-acceptance may be a major component of the allostatic load present in women with PVD, only to be exacerbated by the sexual dysfunction precipitated by the pain of intercourse. Mindfulness-based CBT appears promising to target both the pain and sexual suffering from PVD.

CONCLUSION

New findings on brain activity associated with recurrent clinical pain, functional brain changes associated with CBT and mindfulness, plus new data on stress systems within the skin along with data on increased stress load in women with PVD, support the use of mindfulness-based CBT for the recurrent pain and sexual suffering from PVD.

Biopsychosocial factors associated with dyspareunia in a community sample of adolescent girls

Although various biopsychosocial factors have been associated with dyspareunia, research to date has focused on retrospective reports of adult women, and lack of consensus regarding etiology remains. By targeting girls at the beginning of their reproductive life, this study aimed to examine the biomedical, behavioral, and psychosocial correlates of chronic painful intercourse in sexually active adolescents compared to pain-free girls. With written informed consent, data were obtained from 1425 girls (12-19 year olds) from seven metropolitan high schools using self-report questionnaires pertaining to gynaecologic/biomedical history, physical/psychological/sexual abuse, anxiety, depression, attitudes towards sexuality, and social support. While the chronic painful intercourse (n = 51) and pain-free comparison group (n = 167) did not differ significantly on biomedical variables, painful intercourse was associated with significantly more pain during tampon insertion, and avoidance of tampons was linked to a fourfold risk of experiencing pain during sex. Cases also reported engaging in significantly more detrimental vulvar hygiene habits than pain-free girls, whereas no significant group differences were observed for self-treatment using over-the-counter antifungal preparations. Sexual abuse, fear of physical abuse, and trait anxiety were identified as significant psychosocial correlates of chronic painful intercourse. A logistic regression further identified pain during first tampon insertion and trait anxiety as statistical predictors of adolescent pain during intercourse. In addition to a possible intrinsic dysfunction in central pain processing, findings suggest that psychological variables, such as anxiety, play a significant role in painful intercourse's very first manifestations in adolescent girls.

Chronic stress in women with localised provoked vulvodynia

BACKGROUND

Localised provoked vulvodynia (former vulvar vestibulitis syndrome) is the most common cause of superficial dyspareunia among young women. In a clinical setting, it is obvious that many women with localised provoked vulvodynia show signs of chronic stress. The objective of this study was to compare chronic stress in a group of women with localised provoked vulvodynia, referred to the vulvar unit at the Division of Obstetrics and Gynecology, Danderyd Hospital, Stockholm, Sweden with control women of the same age and educational level, using two independent methods.

METHODS

Forty-three women with localised provoked vulvodynia and 35 healthy control women underwent a gynecological examination, filled in a health questionnaire, and self-collected saliva for analysis of cortisol at awakening and after 15, 30 and 45 min (morning awakening cortisol). Thirty-three patients and 28 controls completed a stress questionnaire.

RESULTS

Morning awakening cortisol was blunted in women with localised provoked vulvodynia (p < 0.05), indicating chronic stress. The stress questionnaire showed more signs of burnout (p < 0.005), and emotional (p < 0.05) and bodily symptoms of stress (p < 0.005) in women with localised provoked vulvodynia compared with control subjects (students t-test).

CONCLUSION

More women with localised provoked vulvodynia showed blunted morning awakening cortisol and reported more symptoms of stress compared with healthy control women of the same age.

HPV infection in women: psychosexual impact of genital warts and intraepithelial lesions

INTRODUCTION

Genital Human Papillomavirus (HPV) infection is the most commonly occurring sexually transmitted viral infection in humans. HPV is a wide family of DNA viruses, which may cause benign skin and mucosal tumors (genital, anal, or oral warts), intraepithelial neoplasias, and/or malignant cancers in different organs. Women are more susceptible to the oncogenic effect of HPVs, mostly at the genital site on the uterine cervix.

AIMS

This review analyzes the impact of: (i) genital warts (GWs) and their treatment; (ii) HPV-related genital, oral, and anal precancerous lesions on women's sexual function.

METHODS

A Medline search was carried out. Search terms were HPV, GWs, intraepithelial neoplasia, cervical cancer, anal cancer, oral cancer, epidemiology, HPV risk factors, sexual dysfunctions, desire disorders, arousal disorders, dyspareunia, vulvar vestibulitis, vulvodynia, orgasmic difficulties, sexual repertoire, couple sexual problems, depression, anxiety, pap smear, screening program, therapy, and vaccines.

MAIN OUTCOME MEASURES

Sexual consequences of HPV infection in women, specifically GWs and intraepithelial HPV-related neoplasia.

RESULTS

Psychosexual vulnerability increases with number of recurrences of HPV infections. Depression, anxiety, and anger are the emotions most frequently reported. However, to date, there is no conclusive evidence of a specific correlation between HPV infection and a specific female sexual disorder. The relationship between HPV and vulvar vestibulitis/vulvodynia-related dyspareunia seems not to be direct. Counseling problems, the role of anti-HPV vaccine, and the concept of the high-risk partner are discussed. The reader is offered a practical approach with clinically relevant recommendations that may prove useful in his/her daily practice when dealing with HPV-infected women and couples.

CONCLUSION

The evidence of psychosexual consequences of HPV-related GWs and intraepithelial lesions is limited. Specific research on the sexual impact of GWs and intraepithelial HPV-related lesion in women is urgently needed.

Evidence-based criteria for pain of interstitial cystitis/painful bladder syndrome in women

OBJECTIVES

No diagnostic physical signs, urologic findings, or laboratory tests are available for interstitial cystitis/painful bladder syndrome (IC/PBS). Its diagnosis is determined by symptoms and the exclusion of mimicking diseases. We hypothesized that certain pain characteristics are sensitive criteria for diagnosing IC/PBS.

METHODS

In women with recent-onset IC/PBS recruited in 2004 to 2006 for the case-control study, "Events Preceding Interstitial Cystitis," we identified the locations of each patient's pain and in a nonleading way asked about the effects of 17 different experiences (criteria) on the pain. We identified a set of criteria that described the largest number of patients in the Events Preceding Interstitial Cystitis study. In a secondary analysis of another cohort recruited by others in 1993 to 1997, the Interstitial Cystitis Database, we determined the proportion of patients captured by these same criteria.

RESULTS

In the Events Preceding Interstitial Cystitis study, pain that worsened with a certain food or drink and/or worsened with bladder filling and/or improved with urination was reported by 151 (97%) of 156 patients. These were the only three criteria that applied directly to the bladder. The same three criteria described the pain of 262 (97%) of 270 women in the Interstitial Cystitis Database who "definitely" had IC/PBS.

CONCLUSIONS

An hypothesis generated in one IC/PBS patient group and tested in another--pain that worsened with certain food or drink and/or worsened with bladder filling and/or improved with urination--was described by 97% of the patients with IC/PBS in each cohort. This triad might describe the pain of IC/PBS and contribute to a sensitive case definition. Estimating specificity awaits comparison with other diseases with similar symptoms.

High-dose methylprednisolone influences the physiology and virulence of Candida albicans ambiguously and enhances the candidacidal activity of the polyene antibiotic amphotericin B and the superoxide-generating agent menadione

Although exposure of Candida albicans cells to high-dose (4 mM) methylprednisolone stimulated microbial growth, germination rate in serum and phospholipase release, it also promoted the recognition of C. albicans cells by polymorphonuclear leukocytes. Pretreatment of C. albicans cells with methylprednisolone did not result in any increase in the pathogenicity of the fungus in intraperitoneal and intravenous mouse assays. Therefore, the virulence of C. albicans is unlikely to increase in patients treated with comparably high-dose methylprednisolone on skin and mucosal membranes. Methylprednisolone treatments also increased the production of conjugated dienes and thiobarbituric acid-reactive substances, and the menadione sensitivity of C. albicans cells, which can be explained by a significant decrease in the specific activities of several antioxidant enzymes. The combination of methylprednisolone with oxidants, e.g. in topical applications, may be of clinical importance when the predisposition to candidiasis is high. Methylprednisolone treatments negatively affected membrane fluidity and decreased the antifungal effects of both the polyene antibiotic nystatin and the ergosterol biosynthesis inhibitor lovastatin, and also enhanced the deleterious effects of the polyene antimycotic amphotericin B on C. albicans cells. These corticosteroid-polyene drug interactions should be considered in the treatment of C. albicans infections in patients with prolonged topical application of corticosteroids.

Sexual sequelae of general medical disorders

That sexual symptoms can signal serious underlying disease confirms the importance of sexual enquiry as an integral component of medical assessment. Data on sexual function are sparse in some medical specialties. However, increased scientific understanding of the central and peripheral physiology of sexual response could help to identify the pathophysiology of sexual dysfunction from disease and medical interventions, and also to ameliorate or prevent some dysfunctions. Many common general medical disorders have negative effects on desire, arousal, orgasm, ejaculation, and freedom from pain during sex. Chronic disease also interferes indirectly with sexual function, by altering relationships and self-image and causing fatigue, pain, disfigurement, and dependency. Current approaches to assessment of sexual dysfunction are based on models that combine psychological and biological aspects.

Symptoms of Interstitial Cystitis, Painful Bladder Syndrome and Similar Diseases in Women: A Systematic Review

PURPOSE

In women symptoms of interstitial cystitis are difficult to distinguish from those of painful bladder syndrome and they appear to overlap with those of urinary tract infection, chronic urethral syndrome, overactive bladder, vulvodynia and endometriosis. This has led to difficulties in formulating a case definition for interstitial cystitis, and complications in the treatment and evaluation of its impact on the lives of women. We performed a systematic literature review to determine how best to distinguish interstitial cystitis from related conditions.

MATERIALS AND METHODS

We performed comprehensive literature searches using the terms diagnosis, and each of interstitial cystitis, painful bladder syndrome, urinary tract infection, overactive bladder, chronic urethral syndrome, vulvodynia and endometriosis.

RESULTS

Of 2,680 screened titles 604 articles were read in full. The most commonly reported interstitial cystitis symptoms were bladder/pelvic pain, urgency, frequency and nocturia. Interstitial cystitis and painful bladder syndrome share the same cluster of symptoms. Chronic urethral syndrome is an outdated term. Self-reports regarding symptoms and effective antibiotic use can distinguish recurrent urinary tract infections from interstitial cystitis in some but not all women. Urine cultures may also be necessary. Pain distinguishes interstitial cystitis from overactive bladder and vulvar pain may distinguish vulvodynia from interstitial cystitis. Dysmenorrhea distinguishes endometriosis from interstitial cystitis, although many women have endometriosis plus interstitial cystitis.

CONCLUSIONS

In terms of symptoms interstitial cystitis and painful bladder syndrome may be the same entity. Recurrent urinary tract infections may be distinguished from interstitial cystitis and painful bladder syndrome via a combination of self-report and urine culture information. Interstitial cystitis and painful bladder syndrome may be distinguished from overactive bladder, vulvodynia and endometriosis, although identifying interstitial cystitis and painful bladder syndrome in women with more than 1 of these diseases may be difficult.

Vulvar vestibulitis syndrome

Vulvar vestibulitis syndrome (VVS) is one of the most common causes of genital pain and pain with sexual intercourse, affecting up to 15% of women. The syndrome is characterized by severe pain on vestibular touch or attempted vaginal entry, exquisite tenderness to palpation with a cotton swab, and often subtle physical findings confined to vestibular erythema. The etiology of VVS is unknown. However, it is probably best to consider VVS as a chronic local inflammatory condition with a wide variety of etiologic causes. The heterogeneity of potential etiologies for VVS results in the use of multiple treatment regimens in clinical practice. Scientifically rigorous studies are sorely needed to determine the best treatment approach.

Vulvar vestibulitis syndrome: A review

Vulvar vestibulitis syndrome (VVS) is a perplexing disease involving pain limited to the vulvar vestibule without objective clinical findings to explain the symptoms. The condition impairs sexual function and creates significant psychological distress. Its cause is unknown, and few randomized studies exist on the efficacy of interventions. This article reviews disease characteristics, possible etiologies, and approaches to management.

Vulvodynia

PURPOSE OF REVIEW

An increasing number of patients present with symptoms of vulvar pain, soreness, burning or irritation, which become chronic. Clinicians are often uncertain of the diagnosis. Terminology and an understanding of aetiology and therapy are evolving.

RECENT FINDINGS

Previous descriptions of vulvodynia have grouped patients according to whether pain is provoked by coitus (vulvar vestibulitis syndrome) or generalized and neuropathic pain (dysesthetic vulvodynia). Recent terminology debates have questioned whether 'vulvodynia' should be replaced by 'dysesthesia' and the term 'vestibulitis' avoided. Definitions of pain provocation, quality, duration, and distribution vary. Prevalence studies suggest one in six women may experience vulvodynia, although such a figure reflects clinic, patient or author reporting bias. Symptoms are as likely to be found in non-white as in white women. Although infection is often blamed, evidence for its role or that of inflammation is minimal. Immunohistochemistry has shown altered density of nerve endings and oestrogen receptors. There may be overlap with other pain syndromes. Several reviews have examined the many therapies available. Pharmacological alteration of nerve conduction (tricyclic antidepressants, gabapentin, local anaesthetics), biofeedback and sometimes surgery are helpful, but not always. Counselling and an understanding between patient and clinician/therapist are important for long-term results.

SUMMARY

Gynaecologists should be aware that they will encounter patients with vulvodynia who will need assessment and management. There are increasing numbers of clinics or clinicians with expertise to whom these patients can be referred.
