A Systematic Review of the Utility of Antidepressant Pharmacotherapy in the Treatment of Vulvodynia Pain

Pharmacological Treatments for Localized Provoked Vulvodynia: A Scoping Review

Introduction

Localized provoked vulvodynia (LPV) is a chronic pain condition without an identifiable cause that is localized to a portion of the vulva and provoked by pressure or touch. LPV is a commonly occurring but poorly understood condition lacking consensus on management.

Method

This scoping review used Arksey and O'Malley's approach to identify and evaluate literature published between 2010 and 2023 that addressed the question: What is the current evidence on the efficacy or effectiveness of pharmacological treatments in the management of LPV?

Results

This review evaluated 18 papers reporting on the efficacy or effectiveness of oral, topical, and injectable medications. Seven of the studies were randomized controlled trials. Oral gabapentin and oral desipramine showed some improvement in sexual function compared to placebo. Small sample sizes and methodological issues limited confidence in interpreting findings. Pain was reduced in descriptive studies of tricyclic antidepressants, milnacipran, injectable anesthetics, and botulinum toxin. Where pain did not improve with treatment, some oral medications improved participants' mood and sexual function. Some topical agents may be effective in reducing peripherally mediated neuropathic pain. Botulinum toxin was the most well-studied injectable but yielded mixed outcomes related to pain, quality of life, and sexual function.

Conclusion

There is a lack of convincing evidence to draw conclusions about the efficacy or effectiveness of pharmacological therapies for LPV. The breadth of therapies for treating LPV warrants the development of evidence-based, consensus guidelines for measuring treatment outcomes and improving comparisons across studies. Recommendations for research include addressing methodological shortcomings and diversifying the participant pool to increase the generalizability of findings.

Behavioral sex therapy and medications associated in the treatment of provoked vulvodynia: efficacy on pain and sexuality in three illustrative cases

This paper tests the hypothesis that medications combined with behavioral sex therapy might lessen pain and restore sexuality in women with provoked vulvodynia. Three women affected by vulvodynia, otherwise healthy, in heterosexual relationship were treated at the Department of Obstetrics and Gynecology in a university hospital. In consecutive sessions of behavioral sex therapy, oral tricyclic antidepressants and vulvar applications of estrogen and hydrocortisone creams were prescribed in association with vaginal dilators and sensate focus exercises. The outcome supports the hypothesis that combined medications and sexual behavior interventions may be effective in lessening pain and restoring sexuality in women with provoked vulvodynia. The different dyadic balances observed in this small case series suggest how to best use this protocol. The positive results appear to be mostly due to behavioral sex therapy that was the new element added to the combination of pharmacological agents commonly used to treat provoked vulvodynia.

Cannabis and Vulvodynia Symptoms: A Preliminary Report

Medical marijuana has a long history of use as an analgesic for chronic pain disorders, including dyspareunia (pain during intercourse), a hallmark of the rare chronic pain disorder vulvodynia. Many women’s health topics remain under investigated. Few studies address cannabis’s potential to treat vulvodynia symptoms despite their dramatic impact on quality of life. Women who had used cannabis and who reported experiencing vulvodynia symptoms (N = 38) completed an online survey assessing symptoms, expectancies regarding cannabis-associated relief from vulvodynia symptoms, cannabis use, and cannabis-related problems. Generally, women expected cannabis to have moderate to large effects on vulvodynia symptoms (d = .63-1.19). Nevertheless, women expected greater relief for burning/stabbing pain than for itching and pain associated with tampon insertion, as well greater relief for dyspareunia than for pain associated with tampon insertion. Those whose symptoms were worse expected more relief from cannabis treatment. Expectations of cannabis-induced relief did not increase frequency of use or problems. These data support the idea that further work is warranted, including placebo-controlled randomized clinical trials to rule out any placebo effects and identify potential adverse side effects from a cannabis treatment for vulvodynia.

Female Sexual Dysfunction: ACOG Practice Bulletin Clinical Management Guidelines for Obstetrician-Gynecologists, Number 213

Female sexual dysfunction encompasses various conditions that are characterized by reported personal distress in one or more of the following areas: desire, arousal, orgasm, or pain (). Although female sexual dysfunction is relatively prevalent, women are unlikely to discuss it with their health care providers unless asked (), and many health care providers are uncomfortable asking for a variety of reasons, including a lack of adequate knowledge and training in diagnosis and management, inadequate clinical time to address the issue, and an underestimation of the prevalence (). The purpose of this document is to provide an overview of female sexual dysfunction, to outline updated criteria for diagnosis, and to discuss currently recommended management strategies based on the best available evidence.

Opioid Adjuncts: Optimizing Opioid Therapy With Nonopioid Medications

In this article, we describe a variety of medications that physicians managing outpatient chronic pain should familiarize themselves with to better aid their approach to multimodal pain therapy. Physicians should always consider the use of an adjuvant or coanalgesic drug as first-line treatments. Although many of these medications are not primarily analgesics, in clinical practice they have independent analgesic effects or synergistic analgesic properties when used with opioids. The use of adjunct analgesics reduces opioid-related adverse effects and optimizes pain management. Although there may be some medication overlap with this section and the ERAS section, the purpose of this article is to understand prolonged use in the outpatient setting to reduce opioid use or limit opioid dose with adjuvant therapy.

Antidepressant-Induced Female Sexual Dysfunction

Because 1 in 6 women in the United States takes antidepressants and a substantial proportion of patients report some disturbance of sexual function while taking these medications, it is a near certainty that the practicing clinician will need to know how to assess and manage antidepressant-related female sexual dysfunction. Adverse sexual effects can be complex because there are several potentially overlapping etiologies, including sexual dysfunction associated with the underlying mood disorder. As such, careful assessment of sexual function at the premedication visit followed by monitoring at subsequent visits is critical. Treatment of adverse sexual effects can be pharmacological (dose reduction, drug discontinuation or switching, augmentation, or using medications with lower adverse effect profiles), behavioral (exercising before sexual activity, scheduling sexual activity, vibratory stimulation, psychotherapy), complementary and integrative (acupuncture, nutraceuticals), or some combination of these modalities.

What Do Patients Want? A Needs Assessment of Vulvodynia Patients Attending a Vulvar Diseases Clinic

INTRODUCTION

Vulvodynia is a chronic pain disorder that negatively impacts the quality of life of affected women.

AIM

The goal of this study was to identify unmet needs among localized provoked vulvodynia patients.

METHODS

A qualitative needs assessment was performed in a subspecialized vulvar clinic in a single academic institution in Canada. Semistructured interviews were conducted, recorded, and analyzed using the constant comparative method of grounded theory to identify common themes.

MAIN OUTCOME MEASURES

Interviews were conducted until theme saturation was achieved.

RESULTS

A diverse sample of 8 patients completed all components of the study. The most prominent unmet needs raised by patients in their interviews were categorized into 3 main themes: (1) challenges related to obtaining a diagnosis of vulvodynia and finding practitioners who are knowledgeable about vulvodynia; (2) challenges related to the current impact of the disease physically, emotionally, and in social relationships with patients' intimate partners; and (3) barriers to adherence with recommended therapy. Solutions recommended by patients include better education of physicians regarding vulvodynia and the development of multidisciplinary programs that provide access to physiotherapy, sex therapy, mindfulness and psychology services on-site, information classes for new patients, and the creation of peer support networks for patients and their partners.

CONCLUSION

A patient-focused needs assessment suggests optimal vulvodynia care requires better education of physicians and a multimodal approach to therapy, ideally with multiple services offered in 1 location.

Vulvar vestibulodynia: strategies to meet the challenge

Vulvodynia is a condition that affects approximately 8% to 12% of women during their lifetimes. Vulvar vestibulodynia (VVD), the most common form of this condition, is characterized by pain with touch at the vulvar vestibule and resulting entryway dyspareunia. Studies suggest a multifactorial etiology; hormonal effects, muscle dysfunction, personality, psychosocial factors, and inflammatory mediators may all play some role in the development of this condition. Both peripheral and central sensitization to pain have been implicated in the development of enhanced pain experienced by women with VVD. Recommendations for the treatment of this condition exist; however, treatments of this condition have not been well studied. Few prospective placebo-controlled trials exist, and many of those that do have failed to show clinically relevant efficacy associated with traditional therapies. New studies into the etiology of this condition, as well as potential new therapies, are emerging, but the optimal approach has yet to be defined. Proper vulvar hygiene is recommended, and traditional therapies such as topical medications and centrally acting oral medications may continue to play a role in treatment. Newer studies elucidating the effects of personality and cognitive factors as well as pelvic floor muscle dysfunction in the development of this condition lend support for the inclusion of cognitive behavioral therapy and physical therapy/surface electromyographic biofeedback in the treatment regimen. Surgery for this condition exists, with success rates of 60% to 90%; however, it is recommended only in cases that have failed to respond to traditional therapy.

Lower Anogenital Tract Disease Therapy Outcomes, COMET, and CROWN: Call for Research Submissions

OBJECTIVES

There is a problem of inconsistent and inappropriate outcome selection for research studies. We can improve the relevance of research results for women and for their physicians and clinicians by encouraging researchers to critically evaluate outcome measures, and use valid, appropriate, standardized measures. To this purpose, and to facilitate synthesis of the evidence, outcomes reported by clinical studies should be standardized for different disease conditions through the development of core outcome sets (COS).

METHODS

There is an international effort for reaching consensus on outcome measures and establishing COS that represent agreed-upon standardized collections of outcome measures that will be reported in all studies within a clinical area. Across clinical specialties, the Core Outcome Measures in Effectiveness Trials (COMET) initiative launched in 2010. In 2014, the editors of women's health journals answered the challenge of COMET and formed the Core Outcomes in Women's Health initiative. The Journal of Lower Genital Tract Diseases is a participating member of the Core Outcomes in Women's Health consortium.

RESULTS

There is broad inconsistency in outcome measures and reporting in the field of lower anogenital tract diseases. No core outcome sets currently exist. Suggested target conditions in anogenital disease are vulvar dermatoses, cervical intraepithelial neoplasia, and vulvodynia.

CONCLUSIONS

Investigators are encouraged to conduct secondary systematic research to determine previously reported primary outcome measures and suggest domains for COS. Core Outcomes in Women's health initiative and COMET encourage the formation of consensus panels of stakeholders (researchers, health care providers, patients, and others) to recommend outcome domains and COS and then publish their report.

Female sexual pain disorders: dyspareunia and vaginismus

PURPOSE OF REVIEW

To analyze literature on sexual pain disorders and to review and summarize the articles published throughout 2013 which contribute to the current knowledge on this subject.

RECENT FINDINGS

By age 40, 7.8% of women reported vulvar pain. Diagnostic and Statistical Manual of Mental Disorders, fifth edition, has combined vaginismus and dyspareunia into the same diagnostic label. The research reviewed in this article seems to differently point toward two conditions, focusing on different aspects both on the etiological and on the treatment area. Higher levels of partner-perceived self-efficacy and lower levels of partner catastrophizing were associated with less pain intensity in women with entry dyspareunia, independent of women's pain perception and self-efficacy. Alexithymia and fear were found to be important etiological factors in vaginismus.

SUMMARY

The present findings did not provide clear evidence in support of the superiority of any treatment and highlight the need for randomized, placebo-controlled trials that compare treatments in the future. A lot of work remained to be done to understand such a complex and multifaceted disturbance as genital sexual pain, but the articles examined showed that we are slowly adding more knowledge on the etiological cause and treatment models for such conditions.

Vulvodynia

Vulvodynia is a complex disorder reported by up to 16% of women in the general population. While most patients describe it as burning, stinging, irritation, or rawness, it is underreported and underrecognized by providers. Vulvodynia is costly both economically and psychologically due to its negative impact on quality of life. Vulvodynia is a diagnosis of exclusion with unknown etiology and may involve multiple sources of pain in the same woman. Thus, there are no clinical or histopathologic criteria for the diagnosis other than consideration and careful evaluation to exclude other causes of pain. Successful therapy often requires a multidisciplinary approach with more than one therapeutic intervention to address the physical, psychological, psychosexual, and relationship components.

Etiology, diagnosis, and clinical management of vulvodynia

Chronic vulvar pain or discomfort for which no obvious etiology can be found, ie, vulvodynia, can affect up to 16% of women. It may affect girls and women across all age groups and ethnicities. Vulvodynia is a significant burden to society, the health care system, the affected woman, and her intimate partner. The etiology is multifactorial and may involve local injury or inflammation, and peripheral and or central sensitization of the nervous system. An approach to the diagnosis and management of a woman presenting with chronic vulvar pain should address the biological, psychological, and social/interpersonal factors that contribute to her illness. The gynecologist has a key role in excluding other causes for vulvar pain, screening for psychosexual and pelvic floor dysfunction, and collaborating with other health care providers to manage a woman's pain. An important component of treatment is patient education regarding the pathogenesis of the pain and the negative impact of experiencing pain on a woman's overall quality of life. An individualized, holistic, and often multidisciplinary approach is needed to effectively manage the woman's pain and pain-related distress.
