Outcome measures for vulval skin conditions: a systematic review of randomized controlled trials

Outcome Measures in Adult Vulvar Lichen Sclerosus: A Systematic Review

OBJECTIVES

Core outcome domains (CODs) for treatment of adult vulvar lichen sclerosus (VLS) have recently been established through a Delphi study. A number of measuring tools are available for evaluating VLS. The aim of this study is to identify available standardized measurement tools for the major CODs for VLS that have recently been defined, namely, physical findings and quality of life (QoL) specific to VLS.

MATERIALS AND METHODS

A systematic search through September 8, 2023, for measuring tools applicable to VLS regarding physical findings and QoL including sexual function or sexual well-being and self-image was performed.

RESULTS

Thirty-five studies were included in the systematic review describing 26 tools covering the following 6 outcome domains: QoL-general health, QoL-lichen sclerosus specific, symptoms, clinical signs, emotional impact, and sexual functioning.

CONCLUSIONS

In current research, there is no uniformity in use of measurement tools for evaluating VLS. The established CODs to evaluate treatment of VLS are applicable for evaluating disease course as well. A comprehensive study to reach consensus regarding measurement of physical findings, QoL-lichen sclerosus specific, sexuality, and self-image taking the predetermined CODs and other factors such as age into account is needed.

EuroGuiderm guideline on lichen sclerosus-Treatment of lichen sclerosus

INTRODUCTION

Lichen sclerosus (LS) is an inflammatory skin disease affecting all ages. LS typically involves the anogenital site where it causes itching and soreness; it may lead to sexual and urinary dysfunction in females and males; however, it may be asymptomatic. First signs of LS are usually a whitening of the genital skin, sometimes preceded by redness and oedema; fissuring, scarring, shrinkage and fusion of structures may follow in its course. LS is associated with an increased risk of genital cancer. LS has a huge impact on the quality of life of affected patients, and it is important to raise more awareness of this not uncommon disease in order to diagnose and treat it early.

OBJECTIVES

The guideline intends to provide guidance on the diagnostic of LS (part 1), highlight important aspects in the care of LS patients, generate recommendations and treatment algorithms (part 2) on topical, interventional and surgical therapy, based on the latest evidence, provide guidance in the management of LS patients during pregnancy, provide guidance for the follow-up of patients with LS and inform about new developments and potential research aspects.

MATERIALS AND METHODS

The guideline was developed in accordance with the EuroGuiDerm Methods Manual v1.3 https://www.edf.one/de/home/Guidelines/EDF-EuroGuiDerm.html. The wording of the recommendations was standardized (as suggested by the GRADE Working Group). The guideline development group is comprised of 34 experts from 16 countries, including 5 patient representatives.

RESULTS

Ultrapotent or potent topical corticosteroids in females and males, adults and children remain gold standard of care for genital LS; co-treatment with emollients is recommended. If standard treatment fails in males, a surgical intervention is recommended, complete circumcision may cure LS in males. UV light treatment is recommended for extragenital LS; however, there is limited scientific evidence. Topical calcineurin inhibitors are second line treatment. Laser treatment, using various wave lengths, is under investigation, and it can currently not be recommended for the treatment of LS. Treatment with biologics is only reported in single cases.

CONCLUSIONS

LS has to be diagnosed and treated as early as possible in order to minimize sequelae like scarring and cancer development. Topical potent and ultrapotent corticosteroids are the gold standard of care; genital LS is often a lifelong disease and needs to be treated long-term.

A systematic review of sexual health consequences among women with lichen sclerosus

Introduction

Lichen sclerosus (LS) is a chronic inflammatory skin condition predominantly affecting the vulva. Studies have shown high rates of sexual dysfunction in patients with LS; however, the sexual effects of the condition are poorly acknowledged.

Objectives

We sought to identify sexual health consequences among women with vulvar LS through systematic review of available literature.

Methods

A systematic review of the literature was conducted to find reports on sexual health consequences among women with LS. PubMed, MEDLINE, and Scopus were queried. Included articles were observational studies evaluating women with LS and their sexual health and randomized controlled trials or comparative studies utilizing a validated sexual health measure before intervention among the same population. Articles must have been written in English and published from January 1991 to April 2022.

Results

The search produced 683 references, including 32 articles that met criteria for full-text review and 20 reported studies that met inclusion criteria. Two studies investigated the impact of LS on interpersonal relationships, 6 studies evaluated sexual symptoms, 16%-60% reported sexual dysfunction, and 22%-56.7% reported dyspareunia. Also described were decreased sexual frequency and satisfaction, negative impact on sexual relationships, and feelings of inadequacy. Eight publications evaluated the Female Sexual Function Index (FSFI); all described studies that demonstrated a central tendency less than 26.55. Four publications evaluated the Female Sexual Distress Scale (FSDS); all demonstrated average scores greater than 12. Two publications evaluated the Female Genital Self-Image Scale (FGSIS), both found decreased scores compared to controls. Four publications evaluated the Dermatology Life Quality Index (DLQI); impact on quality of life was small to very large, with sexual difficulties affecting most study patients. One publication evaluated the Vulvar Quality of Life Index (VQLI); sexuality was the second highest-scoring subgroup.

Conclusions

Sexual health consequences of LS include sexual pain, dysfunction, and distress; negative genital self-image; and negative impact on sexual relationships. Women with LS experience a negative impact on quality of life, particularly related to sexual functioning.

Quality of life impact and treatment response in vulval disease: Comparison of 3 common conditions using the Vulval Quality of Life Index

BACKGROUND/OBJECTIVES

To compare the quality of life in patients with vulval lichen sclerosus (VLS), vulval lichen planus (VLP) and chronic vulvovaginal candidiasis (CVVC), as measured by the Vulval Quality of Life Index (VQLI).

METHODS

A retrospective, single-centre cohort study was conducted at a combined dermatology and gynaecology practice from March 2018 to November 2021. VQLI scores and patient data were systematically collected and recorded in an online patient database. Treatment regimens were individualised and titrated to clinical response.

RESULTS

Over 3 years, a total of 200 women were recruited: 59 with CVVC, 79 with VLP and 62 with VLS. The median duration of follow-up for all patients was 45.43 (16.25-80.89) weeks. At baseline, the median (interquartile range [IQR]) VQLI score was 24.00 (19.00-31.00), 21.00 (12.00-26.00) and 14.00 (7.00-26.00) for CVVC, VLP and VLS, respectively. At follow-up, the median (IQR) VQLI score for CVVC, VLP and VLS was 9.00 (3.00-15.00), 9.00 (3.00-16.00) and 5.00 (2.00-10.00), respectively. All three groups showed a significant improvement in VQLI score (p < 0.0001). At baseline, the highest scoring domains were 'Sexual Function' for CVVC and 'Future Health Concerns' for VLP and VLS. At follow-up, the highest scoring domains were 'Sexual Function' for CVVC and VLP, and 'Future Health Concerns' for VLS.

CONCLUSIONS AND RELEVANCE

Vulval disease has an immense impact on QOL, especially in patients with CVVC. The VQLI is useful to clinicians in identifying the unique impact of each vulval condition on a patient's QOL in order to provide better patient-focussed care.

The Quality and Quantity of Lower Genital Tract Research Across Multiple Journals

OBJECTIVE

This study aimed to determine the quantity and quality of lower genital tract disease (LGTD) research by topic published across a variety of gynecology and dermatology journals.

METHODS

Authors accessed all articles that were rejected (1,111, 59.5%) and accepted (755, 40.5%) by the Journal of Lower Genital Tract Disease (JLGTD) from 2008 to 2020. Studies were categorized by key topic: Cervix, Human Papillomavirus, Vulva, Vagina, Anal, and Other. Studies were further subcategorized based on methodology. These data were compared with all LGTD publications from 2018 to 2020 in 4 other widely recognized journals (Obstetrics and Gynecology, The British Journal of Obstetrics and Gynaecology, JAMA Dermatology, and the British Journal of Dermatology).

RESULTS

Most JLGTD-accepted submissions were related to the cervix (298/755, 39.5%) and vulva (189/755, 25.0%). Rates of acceptance were similar across all key topic areas. Only 3.2% of publications in the other 4 journals (92/2,932) were related to LGTD topics. Across all 5 journals, vulva studies were most commonly case reports/case series (82/218, 37.6%), with a low prevalence of systematic reviews/meta-analyses (4/218 1.8%). In comparison, cervix studies had the highest number of systematic reviews/meta-analyses (14/317, 4.4%) and the lowest number of case reports (14/317, 4.4%).

CONCLUSIONS

Vulvar research is of lower quality compared with cervix research published across 5 journals. Comparing accepted versus rejected articles in JLGTD, there is no publication bias against vulva topics noted; rather, the overall research quality in vulva is lower than that of cervical disease. This is a call to action for higher quality vulvar research.

Development and Validation of a Clinical Grading Scale to Assess the Vulvar Region: The Vulvar Architecture Severity Scale

BACKGROUND

The vulva is composed of aesthetic units that can be affected differently by vulvar conditions. A reliable, comprehensive, and quick-to-use clinical scoring system is required to assess the disease extent in the vulvar area.

OBJECTIVES

The aim of this study was to develop and validate a grading scale based on the aesthetic unit principle to evaluate the extent of vulvar lichen sclerosus (VLS).

METHODS

After reviewing photographs of 100 patients affected by VLS, the authors targeted the aesthetic units most frequently affected. The disease signs were recorded and graded in 4 levels of severity (none, mild, moderate, severe) taking into account the vulvar architecture and skin involvement. To validate the scale, 14 observers were asked to apply it to photographs of 25 VLS patients on 2 different occasions. Intra- and inter-observer reliabilities were determined employing Pearson's and intraclass correlation coefficients.

RESULTS

A 6-region, 4-point grading system was designed and identified as the Vulvar Architecture Severity Scale (VASS). In all 6 areas, the Pearson's r was greater than 0.9 (mean, 0.994; 95% confidence interval [CI] = 0.992), indicating that the intra-observer reliability of the VASS was consistent over time (P < 0.001). Intraclass correlation at time 1 was 0.928 (95% CI = 0.910, 0.943) and at time 2 was 0.944 (95% CI = 0.931, 0.996), indicating a high reliability level among different observers.

CONCLUSIONS

The VASS is a reliable scale to assess the severity of VLS, and it might be considered as an outcome measure in future VLS trials.

A Qualitative Exploration of Women's Experiences of Living With Chronic Vulvar Dermatoses

BACKGROUND

Many vulvar dermatoses (VDs) are chronic and cannot be "cured," thus affected women must learn to live with the impact of the disease, and its treatment, on their quality of life.

AIM

To qualitatively investigate the impact of VDs on women's quality of life through firsthand accounts.

METHODS

12 women, 7 with lichen sclerosus and 5 with erosive vulvovaginal lichen planus recruited from a vulvar disease clinic participated in in-depth, exploratory interviews. Scripts were analyzed by applying a thematic network. The following steps were used: (1) coding the text, (2) development of descriptive themes, and (3) generation of thematic networks.

OUTCOMES

The main outcome explored was the narrative experiences of women living with VDs.

RESULTS

A global theme of suffering emerged. Themes associated with this suffering were organized under the themes of isolation, interference, and grieving. Women felt isolated because they felt unable to talk about their suffering; experienced a lack of external validation and support; and felt different as individuals, women, and sexual beings. Most women expressed negative views of their genitalia. Women spoke of the VDs, and its management, as interfering with thoughts, activities, and sex life. Symptoms were described as all-encompassing. Women spoke about limiting and/or avoiding daily activities and, in particular, sexual activities. Women described diminished sexual pleasure and experienced loss in their intimate relationships. Women described an ongoing grieving process; anger and sadness over the loss of their former healthy self; the burden of ongoing treatment; and attempts to cope and accept their current condition.

CLINICAL IMPLICATIONS

The findings suggest that assessment of women with VDs should include a detailed history of the impact of the VDs on women's psychological and sexual health.

STRENGTHS AND LIMITATIONS

A strength of this study is that we openly explored the lived experiences of women who had been clinically diagnosed with vulvar lichen sclerosus and erosive vulvovaginal lichen planus. A limitation is that the findings may not represent the experience of women living with VDs who do not wish to discuss their VDs or who are undiagnosed, untreated, and/or treated by other health-care providers.

CONCLUSIONS

Women described profound impact of VDs on psychological and sexual health. Sadownik LA, Koert E, Maher C, et al. A Qualitative Exploration of Women's Experiences of Living With Chronic Vulvar Dermatoses. J Sex Med 2020;17:1740-1750.

Fact or Fiction? Adipose-Derived Stem Cells and Platelet-Rich Plasma for the Treatment of Vulvar Lichen Sclerosus

OBJECTIVE

The aim of the study was to summarize and review the evidence for the efficacy and safety of adipose-derived stem cells (ADSCs) and platelet-rich plasma (PRP) for the treatment of vulvar lichen sclerosus (LS).

MATERIALS AND METHODS

PubMed/MEDLINE, Ovid, Web of Science, and clinicaltrials.gov were searched from inception up to May 7, 2018.

RESULTS

Seven observational studies were identified, with a total of 98 patients. Both ADSCs and PRP were reported to improve symptoms, quality of life measures, as well as clinical and histological signs of vulvar LS. There is a strong risk of biased estimates of treatment effect.

CONCLUSIONS

Current evidence is weak for ADSCs and/or PRP as treatment for vulvar LS. Further research is needed before recommending this therapy.

The Impact of Inflammatory and Infectious Diseases of Vulvar on Quality of Life

Objectives

This study aimed to evaluate the effects of vulvar dermatoses (VD) and vulvar infections (VE) on anxiety, depression scores, general, and dermatological quality of life (QOL) of women.

Methods

We conducted a cross-sectional survey on patients diagnosed with VD and VE. All patients were assessed using a sociodemographic form, Skindex-29 scale, World Health Organization QOL (WHOQOL) BREF scale, Hamilton anxiety rating scale (HAM-A), Hamilton depression rating scale (HAM-D).

Results

HAM-A score was significantly higher in the VD group than in the control group. Based on age groups, all subscales of Skindex-29 were found to be higher in women > 50 years. For women with severe pruritus, the symptom subscale was higher in patients with skin involvement and the function and emotion subscales were higher in patients with and emotion subscales were higher in patients with mucosal involvement.

Conclusions

We found that VD was particularly significantly associated with decreased QOL.

Variation in outcome reporting in endometriosis trials: a systematic review

OBJECTIVE

We reviewed the outcomes and outcome measures reported in randomized controlled trials and their relationship with methodological quality, year of publication, commercial funding, and journal impact factor.

DATA SOURCES

We searched the following sources: (1) Cochrane Central Register of Controlled Trials, (2) Embase, and (3) MEDLINE from inception to November 2014.

STUDY ELIGIBILITY

We included all randomized controlled trials evaluating a surgical intervention with or without a medical adjuvant therapy for the treatment of endometriosis symptoms.

STUDY DESIGN

Two authors independently selected trials, assessed methodological quality (Jadad score; range, 1-5), outcome reporting quality (Management of Otitis Media with Effusion in Cleft Palate criteria; range, 1-6), year of publication, impact factor in the year of publication, and commercial funding (yes or no). Univariate and bivariate analyses were performed using Spearman Rh and Mann-Whitney U tests. We used a multivariate linear regression model to assess relationship associations between outcome reporting quality and other variables.

RESULTS

There were 54 randomized controlled trials (5427 participants), which reported 164 outcomes and 113 outcome measures. The 3 most commonly reported primary outcomes were dysmenorrhea (10 outcome measures; 23 trials), dyspareunia (11 outcome measures; 21 trials), and pregnancy (3 outcome measures; 26 trials). The median quality of outcome reporting was 3 (interquartile range 4-2) and methodological quality 3 (interquartile range 5-2). Multivariate linear regression demonstrated a relationship between outcome reporting quality with methodological quality (β = 0.325; P = .038) and year of publication (β = 0.067; P = .040). No relationship was demonstrated between outcome reporting quality with journal impact factor (Rho = 0.190; P = .212) or commercial funding (P = .370).

CONCLUSION

Variation in outcome reporting within published endometriosis trials prohibits comparison, combination, and synthesis of data. This limits the usefulness of research to inform clinical practice, enhance patient care, and improve patient outcomes. In the absence of a core outcome set for endometriosis we recommend the use of the 3 most common pain (dysmenorrhea, dyspareunia, and pelvic pain) and subfertility (pregnancy, miscarriage, and live birth) outcomes. International consensus among stakeholders is needed to establish a core outcome set for endometriosis trials.

Report from the kick-off meeting of the Cochrane Skin Group Core Outcome Set Initiative (CSG-COUSIN)

A major obstacle of evidence-based clinical decision making is the use of nonstandardized, partly untested outcome measurement instruments. Core Outcome Sets (COSs) are currently developed in different medical fields to standardize and improve the selection of outcomes and outcome measurement instruments in clinical trials, in order to pool results of trials or to allow indirect comparison between interventions. A COS is an agreed minimum set of outcomes that should be measured and reported in all clinical trials of a specific disease or trial population. The international, multidisciplinary Cochrane Skin Group Core Outcome Set Initiative (CSG-COUSIN) aims to develop and implement COSs in dermatology, thus making trial evidence comparable and, herewith, more useful for clinical decision making. The inaugural meeting of CSG-COUSIN was held on 17-18 March 2015 in Dresden, Germany, as the exclusive theme of the Annual Cochrane Skin Group Meeting. In total, 29 individuals representing a broad mix of different stakeholder groups, professions, skills and perspectives attended. This report provides a description of existing COS initiatives in dermatology, highlights current methodological challenges in COS development, and presents the concept, aims and structure of CSG-COUSIN.

Core domain and outcome measurement sets for shoulder pain trials are needed: systematic review of physical therapy trials

OBJECTIVES

To explore the outcome domains and measurement instruments reported in published randomized controlled trials of physical therapy interventions for shoulder pain (rotator cuff disease, adhesive capsulitis, or nonspecific shoulder pain).

STUDY DESIGN AND SETTING

We included trials comparing physical therapy to any other intervention for shoulder pain, indexed up to March 2015 in CENTRAL, MEDLINE, EMBASE, or CINAHL Plus. Two authors independently selected trials for inclusion and extracted information on the domains and measurement instruments reported.

RESULTS

We included 171 trials. Most trials measured pain (87%), function (72%), and range of movement (67%), whereas adverse events, global assessment of treatment success, strength, and health-related quality of life were measured in 18-27% of trials, and work disability and referral for surgery were measured in less than 5% of trials. Thirty-five different measurement instruments for pain and 29 for function were noted. Measurement of function increased markedly from 1973 to 2014. In rotator cuff disease trials, there was a more frequent measurement of pain and strength and a less frequent measurement of range of movement compared with adhesive capsulitis trials.

CONCLUSIONS

There was wide diversity in the domains and measurement instruments reported. Our results provide the foundation for the development of a core domain and outcome measurement set for use in future shoulder pain trials.

Vulvovaginal photodynamic therapy vs. topical corticosteroids in genital erosive lichen planus: a randomized controlled trial

BACKGROUND

Genital erosive lichen planus (GELP) in women is a chronic inflammatory disease characterized by painful vulval and vaginal erosions. Topical photodynamic therapy (PDT) is increasingly used in premalignant and malignant diseases and may have an effect in inflammatory diseases.

OBJECTIVES

To assess the feasibility, efficacy and safety of hexyl 5-aminolevulinate-hydrocloride (HAL)-PDT in GELP.

METHODS

Forty women, diagnosed with GELP at a specialized vulva clinic, were randomized to one session HAL-PDT in vulva and/or vagina (n = 20) or daily applications of clobetasol propionate 0·05% ointment in vulva and optional hydrocortisone acetate 1·0% foam in vagina for 6 weeks (n = 20). After 6 weeks, all patients were allowed to use topical corticosteroids as needed. Clinical examinations were performed at weeks 0, 6 and 24, using a clinical score developed for the study. All patients wrote a weekly log on pain, topical corticosteroid use and adverse events.

RESULTS

Three patients, all in the corticosteroid group, withdrew from the study after 1-3 weeks. The mean reduction in clinical scores was similar in the PDT group and the corticosteroid group; 25% vs. 22% after 6 weeks (P = 0·787) and 35% vs. 38% after 24 weeks (P = 0·801). The mean reduction in pain visual analogue scale scores was 38% vs. 55% after 6 weeks (P = 0·286) and 39% vs. 12% after 24 weeks (P = 0·452). Patients in the PDT group reported significantly less topical corticosteroid use during weeks 7-24 than those in the corticosteroid group. No major adverse events were reported.

CONCLUSIONS

Vulvovaginal HAL-PDT seems to be an effective and safe treatment for GELP.

Spanish consensus on vulvar disorders in postmenopausal women

INTRODUCTION

The consequences of vulvar disorders in terms of health, sexuality, and quality of life are usually undervalued, with disparities in the conceptual, diagnosis and treatment criteria.

AIM

The objective of this guide will be to analyse the factors associated with the diagnosis and treatment of vulvar disorders and to provide recommendations for the most appropriate diagnostic and therapeutic measures.

METHODOLOGY

A panel of experts from various Spanish scientific societies related to sexual health (Spanish Menopause Society [SMS] and the Asociación Española de Patología Cervical y Colposcopia [AEPCC]) met to reach a consensus on these issues and to decide the optimal timing and methods based on the best evidence available.

RESULTS

We recommend a biopsy of all vulvar lesions with an uncertain diagnosis, especially with asymmetry, irregular borders, variegated and irregular colour and diameter >6mm. For vulvodynia, we recommend the use of lubricants or topical treatments with lidocaine or bupivacaine, amitriptyline, baclofen or triamcinolone. For vulvar epithelial disorders, we recommend beginning with topical corticosteroids of moderate to high potency. For sexual dysfunction, a multidisciplinary approach is the best management strategy in these patients.

Variations in the reporting of outcomes used in systematic reviews of treatment effectiveness research in bladder pain syndrome

This paper investigates the quality of outcomes reported in systematic reviews and randomised controlled trials (RCTs) of bladder pain syndrome and its relationship with study quality and journal impact factor. We searched until August 2013 the Cochrane Library, EMBASE, Medline, CINAHL, LILACS and SIGLE, without language restrictions. Quality of outcome reporting in systematic reviews and constituent RCTs was assessed using a 6-point scale. Overall study quality was assessed using the AMSTAR and Jadad scoring systems, and impact factor in the year of publication was noted. Spearman's rank correlation was calculated. There were 8 systematic reviews, with a total of 28 RCTs (1732 patients), reporting 5 outcomes using 19 different measurement scales. The outcomes reported in individual RCTs were urinary symptoms (100%), pain (64%), quality of life (39%), general wellbeing (36%) and bladder capacity (36%). The mean quality of outcomes reported was 1.63 (95% CI 0.29-2.96) for systematic reviews and 3.25 (95% CI 2.80-3.70) for RCTs. The quality of outcomes reported showed correlation with overall study quality (0.90, 95% CI 0.79-0.95, p<0.0001) but not with journal impact factor (0.07, 95% CI -0.31-0.43, p=0.35). Multivariable linear regression showed a relationship between quality of outcome reporting and study quality (β=0.05, p<0.0001), adjusting for effects of study type, impact factor and journal type. There is a need to generate consensus over a set of core outcomes in bladder pain syndrome using standardised reporting tools and to disseminate these through good publication practice.
