NCT ID: NCT02712814 Completed - Clinical trials for Provoked Localized Vulvodynia

Subtypes of Provoked Vestibulodynia

Start date: November 30, 2016
Phase:
Study type: Observational

The proposed study will evaluate a clinical algorithm for the diagnosis and treatment of provoked vestibulodynia (PVD). The algorithm, distinguishes between four subtypes of PVD: hormonally mediated PVD, hypertonic pelvic floor dysfunction, congenital neuroproliferative PVD and acquired neuroproliferative PVD, based on a patient's history and physical exam. The study will follow patients diagnosed with PVD, for one year, and evaluate the treatment outcome in the different subgroups. Investigators hope that conducting a prospective study, showing clinical benefit and improved outcome for patients classified according to this method may change the common practice of "trial and error" based treatment, and will improve clinical results.

NCT ID: NCT02704234 Completed - Pain Clinical Trials

Acupuncture for Vulvodynia: A Pre-pilot Study

Start date: February 23, 2018
Phase: N/A
Study type: Interventional

Vulvodynia is a women's pain condition. Women have pain in their vulva, the area in their genitals between the vagina and labia (lips of the vagina). They also have pain when they have sexual intercourse or insert anything in the vagina. Sometimes they have so much pain, that they cannot have sex. This research is being done for two reasons. The first reason is to test a set of special needles called double-blinded acupuncture needles to give acupuncture treatments (one is a real needle and the other is a fake needle). The second reason is to develop a protocol (checklist) that will be used in this and future studies, and to identify and resolve any procedural problems. The protocol will be first tested by the principal investigator who is also an acupuncturist. The investigator will perform acupuncture using the protocol, if necessary change the protocol, and then teach a second acupuncturist using the modified protocol how to use the double-blinded acupuncture needles. The real needle called the penetrating needle penetrates the skin. The fake needle called the non-penetrating placebo touch needle does not penetrate the skin but it touches the skin so it feels like a needle is being inserted. It has a blunt tip. Participants can't see which needle they are getting acupuncture with because the needles are housed in a double-blinded needle device which has two tubes (an inner and an outer) that neither the acupuncturists nor the participants can see through. If a fake acupuncture needle can be used in acupuncture research like a sugar pill is used for drug studies to see how well the real medicine works, the investigators can see how effective acupuncture is. The investigators will be testing these needles to treat participants with vulvodynia.

NCT ID: NCT02543593 Completed - Clinical trials for Provoked Vestibulodynia

Efficacy of Transcranial Direct-Current Stimulation (tDCS) for Provoked Vestibulodynia : a Triple Blind Randomized Controlled Trial

PVD/tDCS
Start date: November 2014
Phase: N/A
Study type: Interventional

Provoked vestibulodynia (PVD) is the most common form of vulvodynia and despite its high prevalence and important sexual, conjugal and psychological deleterious repercussions, effective evidence-based interventions remain limited. For a high proportion of women, significant pain persists despite the currently available treatments. Transcranial direct-current stimulation (tDCS) was shown to be effective in various chronic pain conditions. So far, only one case report study has shown significant pain reduction in women with vulvodynia. The main goal of this randomized controlled trial is to evaluate the efficacy of tDCS in women with PVD compared to sham tDCS. Forty women diagnosed with PVD, by a gynecologist following a standardized protocol will be randomized to either active or sham tDCS for ten 20 minute sessions of 2 mA stimulation over a 2-week period. Outcome measures will be collected at baseline, after treatment and at 3-month follow-up. The primary outcome is pain during intercourse assessed with a numerical rating scale (NRS). Secondary measurements focus on sexual function, vestibular pain sensitivity, psychological distress, treatment satisfaction and Patient Global Impression of Change (PGIC). The investigators expect that active tDCS treatment will significantly reduce pain during intercourse (post-treatment and 3-month follow-up compared to pre-treatment assessment). This trial will provide important information for determining the efficacy of a novel and promising intervention for women with PVD.

NCT ID: NCT02404961 Completed - Vulvodynia Clinical Trials

Women's Health Study: Immunological Factors and Risk of Vulvodynia

Start date: September 2009
Phase:
Study type: Observational

The investigators plan to study the etiology of vulvodynia, a condition characterized by chronic vulvar discomfort, most often described as burning pain, occurring in the absence of relevant visible findings or a specific, clinically identifiable, neurologic disorder. Our hypothesis is that vulvodynia is the result of an altered immuno-inflammatory response mechanism that occurs as a consequence of reproductive, gynecologic, environmental, or psychological exposures, with abnormal vaginal microflora and genetic polymorphisms as potential modifiers of the effects of interest. Therefore, the investigators propose to collect information about reproductive, gynecological and environmental exposures, psychological trauma and psychiatric morbidity, and biological markers of immuno-inflammation and nerve fiber proliferation.

NCT ID: NCT02393911 Not yet recruiting - Vulvodynia Clinical Trials

Dysbiosis in Localized Provoked Vulvodynia (LPV)

DMLPV
Start date: March 2015
Phase: Phase 3
Study type: Interventional

Currently, the pathogenesis of Localized Provoked Vulvodynia (LPV) has not been elucidated. Few observations may point to involvement of the microbiome: the association of LPV with preceding chronic recurrent candidiasis, and the reports of the beneficial effect of a diet avoiding oxalate on Vulvodynia. Studies in the new field of microbiome research focus on the composition of overall microorganisms in our body and their impacts on our health. Changes in the composition of the vaginal microbiota (dysbiosis) have been linked with different health and disease states. We have also shown recently that women can be divided into 2 groups according to the composition of their vaginal microbiome. The proposed study will compare the vaginal microbiome of women with severe LPV, not treated by diet and otherwise healthy, to women without LPV (we will also compare our results to the NIH HMP data). Vaginal pH and date of menstrual cycle will be checked. We propose that dysbiosis in the vaginal microbiota may trigger the development of LPV.

NCT ID: NCT02197429 Completed - Pain Clinical Trials

Acupuncture for the Treatment of Vulvodynia

Start date: February 2012
Phase: N/A
Study type: Interventional

A randomized controlled pilot study was conducted to evaluate the effect of an acupuncture protocol for the treatment of vulvodynia. Hypotheses: 1. Acupuncture reduces vulvar pain and dyspareunia in women with vulvodynia. 2. Acupuncture increases sexual function in women with vulvodynia.

NCT ID: NCT01996384 Completed - Vulvodynia Clinical Trials

Provoked, Localized Vulvodynia Treatment With Acupuncture and Lidocaine Pilot Study

Start date: November 2013
Phase: Phase 1
Study type: Interventional

The investigators research project is a randomized, controlled, single-blinded, feasibility pilot study. The investigators will study the feasibility of a novel treatment for women with Provoked Localized Vulvodynia (PLV) with acupuncture and 5% lidocaine cream. Lidocaine is a numbing agent and common first treatment for this disorder. Acupuncture is a treatment commonly used for other pain disorders. The investigators will compare two types of acupuncture (classical and non-classical) as a treatment for PLV, in addition to 5% lidocaine cream. Researchers want to determine if acupuncture is acceptable and convenient to women with PLV. The investigators hypothesize that classical acupuncture and 5% lidocaine cream will be better than non-classical acupuncture and 5% lidocaine cream to decrease PLV pain.

NCT ID: NCT01935063 Completed - Dyspareunia Clinical Trials

Study to Compare the Efficacy of Cognitive-behavioral Couple Therapy and Lidocaine for Provoked Vestibulodynia

CBCT-RCT
Start date: March 6, 2014
Phase: N/A
Study type: Interventional

Chronic pain problems involving the female reproductive system are major health concerns for all women. Poorly understood, they entail great personal and financial cost. One such condition is vulvodynia, or chronic unexplained vulvar pain, which has a prevalence of 16%. Despite its negative impact on psychosexual and relationship satisfaction, there is little research examining empirically-tested treatments for afflicted couples. The proposed research builds on findings from our work focusing on the impact of relational factors on vulvodynia, and our previous research evaluating the efficacy of group cognitive-behavioral therapy for this problem. This two-centre randomized clinical trial aims to assess the efficacy of a novel, 12-week targeted couple therapy (CBCT) for women with vulvodynia in comparison to one of the most commonly prescribed first line medical interventions, topical lidocaine. Primary research question: Is there a significant difference between the two treatments on women's pain during intercourse post-treatment? Secondary research questions will assess for significant differences between the two treatments post-treatment and at 6-month follow-up on multidimensional aspects of pain using the McGill Pain Questionnaire, women and partners' sexuality (sexual function and satisfaction), psychological adjustment (anxiety, depression, catastrophizing, self-efficacy, attributions, and quality of life), relationship factors (partner responses, couple satisfaction, attachment, and communication styles), and self-reported improvement and treatment satisfaction. Results of this study will improve the health and quality of life of patients with vulvodynia by rigorously testing the efficacy of a novel couples treatment.

NCT ID: NCT01829204 Recruiting - Bacterial Vaginosis Clinical Trials

Prospective Data Bank Creation to Study Vaginal Conditions

CRIPB-13-002
Start date: April 2013
Phase:
Study type: Observational [Patient Registry]

The purpose of this study is to identify and elucidate the pattern and perhaps role of atypical proteins, cytokines and vaginal microbial flora in the pathogenic mechanisms involved in the development of vulvodynia, recurrent fungal and bacterial vaginosis and preterm labor.

NCT ID: NCT01753258 Completed - Pregnancy Clinical Trials

Outcomes of Delivery in Patients With Dyspareunia

Start date: January 2013
Phase: N/A
Study type: Observational

The focus of this pilot study is to determine if a woman who experiences pain during sexual intercourse has a higher risk of complications during labor and delivery secondary to pelvic floor dysfunction, anxiety and intolerance towards pelvic examinations. Furthermore, it is unclear whether women with prepartum dyspareunia experience an improvement following vaginal delivery. While physicians may expect that vaginal birth improves dyspareunia due to the stretching effect on pelvic floor, to date, there is insufficient evidence to support this claim. The Investigators plan to prospectively study 200 patients at our Institution, collect information regarding birth and follow them, via questionnaires, regarding their dyspareunia postpartum.
