CO2-Laser therapy and Genitourinary Syndrome of Menopause: A Systematic Review and Meta-Analysis

Physical energies for the management of genitourinary syndrome of menopause: An overview of a systematic review and network meta-analysis

BACKGROUND

Energy-based devices (laser and radiofrequency) have been used to treat genitourinary syndrome of menopause (GSM).

OBJECTIVES

To evaluate the efficacy and safety of physical energy use in managing GSM symptoms.

SEARCH STRATEGY

Five databases were searched from inception to December 2022. Language restrictions were not imposed.

SELECTION CRITERIA

We included all Cochrane and non-Cochrane systematic reviews with or without meta-analyses that described postmenopausal women with symptoms of GSM treated with physical energy.

DATA COLLECTION AND ANALYSIS

We performed a network meta-analysis using frequentist methods to calculate standardized mean differences (SMDs) and their corresponding 95% confidence intervals (CIs). Methodological and reporting quality were assessed using the Assessment of Multiple Systematic Reviews (AMSTAR 2).

MAIN RESULTS

Nine reviews were included in the overview, six of which were meta-analyses. Four randomized controlled trials, representing 218 participants and nine different study arms, met the criteria for inclusion in our component network meta-analysis. Confidence in review findings was low in six reviews and critically low in three. Our network meta-analysis results showed that premarin (SMD 2.60, 95% CI 7.76-3.43), conjugated estrogens (SMD 2.13, 95% CI 1.34-2.91), carbon dioxide laser (SMD 1.71, 95% CI 1.10-2.31), promestriene (SMD 1.41, 95% CI 0.59-2.24), and vaginal lubricant (SMD 1.37, 95% CI 0.54-2.20) were more effective than sham for reducing sexual dysfunction, with a consequent increase in Female Sexual Function Index (FSFI). Two studies showed a high risk of bias, owing to a lack of blinding.

CONCLUSION

Several gaps in the use of physical energy for managing GSM still need to be addressed. The small number of blind clinical trials made the results fragile.

The Efficacy of CO2 Vaginal Laser in the Treatment of Recurrent, Post-Coital and Interstitial Cystitis: A Multicentric Prospective Study

Background: This multicentric prospective study was carried out at Fondazione Policlinico Universitario Campus Bio Medico and Ospedale di Stato of St. Marino Republic. Between 1 January 2019, and 31 December 2022, all pre- and post-menopausal women diagnosed with recurrent, post-coital, and interstitial cystitis at both centers were included in the study. The main aim of the study was to assess the effectiveness of vaginal CO2 laser treatment, alone or combined with intravesical hyaluronic acid instillations, in managing cystitis symptoms, such as dysuria, pollakiuria, and urgency, across the entire patient cohort. The secondary objective was to investigate the reduction in number of annual cystitis episodes post-treatment. Methods: Each woman underwent three to four sessions of micro-ablative CO2 vaginal laser treatment. A follow-up examination was conducted 12 months after the final laser session (up to December 2023), during which a post-treatment VAS assessment evaluated dysuria, daily pollakiuria, and urgency. The enrolled patients recorded the number of cystitis episodes experienced during the 12-month pre- and post-treatment period. Results: Results indicated the laser's efficacy in reducing the total number of cystitis episodes per year and an improvement in symptoms up to one year post-treatment. Greater efficacy of the CO2 laser treatment, particularly when combined with intravesical hyaluronic acid instillation, was observed in both pre- and post- menopausal women. Conclusions: Fractional CO2 laser therapy represents a safe and efficacious, non-hormonal approach for pre- and post-menopausal women diagnosed with recurrent, post-coital, and interstitial cystitis.

Fractional and Microablative CO2 LASER and Radiofrequency in the Treatment of Genitourinary Syndrome of Menopause: A Descriptive Study

Objectives: This study aimed to evaluate the vagina clinically, cytologically, and histologically before and after treating genitourinary syndrome of menopause (GSM) with fractional microablative carbon dioxide LASER (CO2L), radiofrequency (RF), and estrogen vaginal cream (CT). Methods: Women with moderate-to-severe symptoms of GSM, denoted by a GSM Visual analog scale (VAS) score of >4, were eligible for this study. The patients were randomized into treatment groups. In the energy groups, three vulvovaginal applications were administered monthly. The CT group used 0.5 mg vaginal estriol cream for 14 consecutive days, followed by twice a week for 4 months. The follow-up visits occurred 120 days after the beginning of the treatments. The same parameters obtained at the first visit were re-evaluated: GSM VAS score, Incontinence Quality of Life Questionnaire (I-QOL), gynecological examination determining Vaginal Health Index (VHI), vaginal smear for Vaginal Maturation Value (VMV), and vaginal biopsy. Results: Seventy-one women were included, 48 completed the study and provided adequate samples for analysis (CO2L [21 patients], RF [15 patients], and CT [12 patients]). GSM symptoms, I-QOL, and VHI significantly improved after all proposed treatments, with no significant differences between them. VMV did not change after any treatment; however, only 22.9% of the patients presented with cytological atrophy before treatment. Histological vaginal atrophy was identified in 6 (12.5%) pretreated vaginal samples. After the intervention, all histological parameters were normalized, no tissue damage was observed, and no major clinical complications were observed. Conclusion: CO2L and RF seem to be good alternatives to CT for GSM treatment, with no tissue damage.

Vaginal dryness: a review of current understanding and management strategies

The issue of vaginal dryness in genitourinary syndrome of menopause (GSM) and its pervasive impact on women's quality of life is often overlooked. Extensive surveys conducted worldwide reveal limited understanding of vaginal dryness among public and health-care providers. Physician knowledge on menopause medicine varies globally, highlighting the need for standardized training. Effective communication between physicians and patients plays a crucial role in diagnosing and treating GSM symptoms. There are multiple treatment options to improve vaginal lubrication, including hormonal and non-hormonal therapies, along with lifestyle modifications. Tailoring treatments to individual patient preferences is crucial for compliance. Overall, GSM is multifaceted, from the prevalence of vaginal dryness to the nuances of treatment preferences. The urgency of widespread education and awareness of this matter must be underscored to meet the aim of enhancing the well-being and quality of life for women.

Comparison of the effect of noninvasive radiofrequency with vaginal estrogen and vaginal moisturizer in the treatment of vulvovaginal atrophy in postmenopausal women: a randomized clinical trial

OBJECTIVE

To compare the effect of noninvasive radiofrequency (RF) with vaginal estrogen (E), and vaginal moisturizer (M) on improving vulvovaginal atrophy (VVA) in women with genitourinary syndrome of menopause.

METHODS

A total of 32 postmenopausal women who met the inclusion criteria were randomized into three intervention arms to receive one of the following treatments: three sessions of noninvasive RF therapy (RF arm); intravaginal estriol cream 1 mg applied daily for 2 weeks, followed by 1 mg applied two times weekly or 1 mg of estradiol vaginal fast-dissolving film applied daily for 2 weeks, followed by 1 mg applied two times weekly (E arm); and intravaginal moisturizer two times a week (M arm). Assessments at baseline and after 4 months were conducted using Vaginal Health Index score, Vaginal Maturation, visual analog scale for VVA symptoms (dyspareunia, dryness, and burning), and Menopause Rating Scale (MRS) for urogenital symptoms. Vaginal wall biopsies were administered to participants who consented, pretreatment and posttreatment (at baseline and after 4 months of follow-up).

RESULTS

After 4 months, the Vaginal Health Index showed an increase of 6.6 points in mean total score in the RF arm, also in the E arm (+7.3 points), with no significant improvement in the M arm (+1.5 points) (interaction effect: RF, E ≠ M, P < 0.001). Regarding vaginal maturation, there was a significant increase in superficial cells in the E arm (+31.3), with no significant changes in the RF (+9.3) and M (-0.5) arms (interaction effect: E ≠ M, P < 0.001). Vaginal pH decreased significantly in the E arm (-1.25), with a similar response in the RF arm (-1.7), with no significant improvement in the M arm (-0.25) (interaction effect: RF, E ≠ M, P < 0.001).There was a significant improvement in the MRS score for VVA symptoms in the three intervention arms, with no predominance of any arm, whereas the improvement in the total MRS score for urogenital symptoms showed a predominance of the RF arm (ΔRF: -7.8; ΔE: -3.5; ΔM: -2.3; RF ≠ E, M). According to histopathologic analysis, there was no statistically significant increase in glycogenation ( P = 0.691) or epithelial cone height ( P = 0.935), despite an increase in the median delta (difference between pretreatment and posttreatment) in the three intervention arms (glycogenation: RF arm Δ = +118.4%; E arm Δ = +130.9%; M arm Δ = +24.9%; epithelial cone height: RF arm Δ = +33.5%; E arm Δ = +18.6%; M arm Δ = +22.3%).

CONCLUSION

The effect of noninvasive RF on the treatment of vulvovaginal symptoms of genitourinary syndrome of menopause was similar to vaginal estrogen, except for hormonal cytology, and superior to vaginal moisturizer, with improvement in some histomorphometric parameters. These findings are promising, especially for the population that cannot or prefers not to use vaginal estrogen therapy.

Sexual Dysfunction and Dyspareunia in the Setting of the Genitourinary Syndrome of Menopause

Sexual dysfunction is a common consequence of the genitourinary syndrome of menopause (GSM). In this book chapter, we discuss the pathophysiology, prevalence, evaluation, and evidence-based management of sexual dysfunction in patients affected by GSM. Additionally, we present an algorithm to guide clinicians in the management and treatment of sexual dysfunction in this setting based on available evidence and best practices.

Fractional CO2 laser for genitourinary syndrome of menopause: evaluating the evidence

The fractionated CO2 laser has been marketed to women for a variety of gynecologic symptoms and conditions, including the genitourinary syndrome of menopause (GSM). The evidence has been limited, precluding conclusions regarding the efficacy and safety of the therapy. However, data from randomized, controlled trials evaluating this technology for GSM are now available. This Practice Pearl addresses the latest data concerning the use of the fractionated CO2 laser for the treatment of GSM.

Carbon dioxide laser therapy for the management of genitourinary syndrome of menopause: A meta‑analysis of randomized controlled trials

Genitourinary symptoms of menopause (GSM) affect ~50% of women after menopause. Recently, CO2 laser therapy has been used for managing GSM but without high quality evidence. The present review assessed the effectiveness of CO2 laser therapy in the management of GSM. PubMed, Embase, Web of Science, CENTRAL and Scopus databases were searched for randomized controlled trials (RCTs), published up to June 30, 2023, comparing CO2 laser and sham laser treatments for GSM management. The outcomes of interest included Female Sexual Function Index (FSFI), Vaginal Health Index (VHI) and visual analog scale (VAS) for dyspareunia, dryness, burning, itching and dysuria. A total of seven RCTs were included in the review and meta-analysis, with 6/7 studies using three sessions of laser therapy, 4-8 weeks apart. Meta-analysis demonstrated no statistically significant difference in FSFI [mean difference (MD), -1.48; 95% CI, -5.85, 2.89; I2=45%] and VHI scores (MD, -0.18; 95% CI, -1.66, 1.31; I2 =72%) between laser and control groups. Meta-analysis also demonstrated no statistically significant difference in VAS scores for dyspareunia (MD, -1.63; 95% CI; -4.06, 0.80; I2=91%), dryness (MD, -1.30; 95% CI, -3.14, 0.53; I2=75%), burning (MD, -0.76; 95% CI, -2.03; 0.51 I2=56%), itching (MD, -0.28; 95% CI, -0.95, 0.38; I2=0%) and dysuria (MD, 0.15; 95% CI, -0.37, 0.67; I2=23%) between the groups. The included RCTs had low risk of bias. In conclusion, meta-analyses of high-quality sham-controlled RCTs indicated that CO2 may not have any beneficial effect on GSM. Limited data and high heterogeneity in meta-analyses in this area of research are important limitations that need to be addressed by future RCTs.

Non-oestrogen-based and complementary therapies for menopause

Women are living a significant portion of their adult lives in the post-reproductive phase, and many seek help for debilitating menopausal symptoms. Every individual's experience of menopausal transition is unique. Adopting a holistic approach to managing the menopause using a combination of lifestyle, hormonal, and non-hormonal interventions is key to maximise the quality of life of affected women. However, many opt to use non hormonal options or have contraindications to using hormonal therapy. Studies have shown that several pharmacological non-hormonal medications such as SSRIs, SSRI/SNRIs, Gabapentin, and Pregabalin are effective for managing vasomotor symptoms as well as other menopausal symptoms. Their main side effects are dry mouth, nausea, constipation, reduced libido, and loss of appetite. Clonidine is the only non-hormonal drug which is licenced for control of vasomotor symptoms in the UK, but has several side effects including dizziness and sleep disturbance. Cognitive Behavioural Therapy is recommended as a treatment for anxiety, sleep problems and vasomotor symptoms related to menopausal transition. Evidence for clinical efficacy and safety of herbal remedies and alternative therapies remains weak. Studies with neurokinin receptor 3 antagonists on women with hot flushes have shown improvement in vasomotor symptoms and results of large-scale studies are awaited.

The Utility of CO2 Laser Treatment of Pelvic Symptoms in Women with Previous Perineal Trauma during Delivery

This study aimed to examine the impact of fractional CO2 laser treatment of pelvic symptoms in women who have undergone perineal trauma from vaginal delivery. It was a retrospective, monocentric analysis that encompassed all women assessed for pelvic discomfort or signs of vulvovaginal atrophy following vaginal delivery between 2013 and 2018. The severity of symptoms was assessed using the Visual Analogue Scale (VAS). Twenty-seven patients met the inclusion criteria and were sorted into two groups: (1) women who had undergone episiotomies during labor (n = 11); and (2) women who had experienced spontaneous tears during vaginal delivery (n = 16). For women with episiotomies, each treatment and subsequent evaluation consistently showed a significant reduction in dyspareunia intensity. A similar positive trend was observed regarding pain at the introitus (7.5 vs. 6.5 after the first treatment, p = 0.03; 6.5 vs. 3 after the second treatment, p = 0.01; 3 vs. 1 after the third treatment, p = 0.01). Among women experiencing spontaneous perineal tears during delivery, there was a notable decrease in dyspareunia following all treatments (8 vs. 7 after the first treatment, p = 0.01; 8 vs. 4 after the second treatment, p = 0.02; 3 vs. 1 after the third treatment, p = 0.03). The impact of laser treatment did not exhibit significant differences between women who underwent episiotomies and those who experienced spontaneous perineal tears. In conclusion, fractional CO2 laser can be regarded as a non-pharmacological option for managing pelvic floor symptoms in women who encountered perineal trauma during delivery, independently from the nature, spontaneity, or iatrogenesis of the perineal laceration.

CO2 Laser versus Sham Control for the Management of Genitourinary Syndrome of Menopause: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

In the context of the menopausal transition, genitourinary syndrome of menopause (GSM) refers to a range of genitourinary symptoms, from vaginal dryness to dysuria and urinary urgency. While hormonal treatments are standard, their associated side effects have driven the exploration of alternatives like vaginal CO2 laser. We aimed to evaluate the randomized controlled trials (RCTs) comparing vaginal CO2 laser treatment for GSM to sham controls. This systematic review sourced four electronic databases until June 2023. The analysis incorporated seven RCTs with 407 women. The CO2 laser and sham control were comparable for most parameters, including the female sexual function index (FSFI) and visual analogue scale (VAS) for dyspareunia, vaginal health index, pH, and patient satisfaction. However, the CO2 laser group showed significant improvement in the vaginal assessment scale for GSM symptoms. Sensitivity analyses revealed that parameters like FSFI showed significant differences in favor of CO2 laser group upon the exclusion of specific studies. In conclusion, vaginal CO2 laser therapy emerges as a promising alternative for GSM management, especially for most bothersome GSM symptoms; however, the need for further well-designed RCTs remains to validate its broad safety and efficacy.

CO 2 laser, radiofrequency, and promestriene in the treatment of genitourinary syndrome of menopause in breast cancer survivors: a histomorphometric evaluation of the vulvar vestibule

OBJECTIVE

This study aimed to compare the efficacy of CO 2 laser, radiofrequency, and promestriene in treating genitourinary syndrome of menopause in women with breast cancer receiving adjuvant therapy and to analyze the clinical and histological findings of the vulvar vestibule.

METHODS

Women with moderate-to-severe symptoms of vulvar atrophy were enrolled. The participants were evaluated according to pretreatment and posttreatment protocols using the visual analog scale and clinical assessments, which included a gynecological examination and vestibular biopsy. Participants were randomly assigned into the laser, radiofrequency, or promestriene groups. Participants in the energy treatment groups underwent three consecutive monthly outpatient vulvovaginal treatment sessions, whereas those in the control group were administered promestriene for 4 months. During a follow-up visit 30 days posttreatment, the participant global posttreatment impression of improvement was evaluated using a Likert scale.

RESULTS

Seventy women completed treatment. Histological vulvar atrophy was identified in four (5.7%) of the pretreatment vulvar samples. Postintervention, all histological parameters were normalized. Significant improvements in symptoms were observed, as all three groups showed a reduction in the visual analog scale score, with no statistically significant differences among them. A high level of satisfaction was reported posttreatment in all groups. No damage to the histological structure of the vulvar vestibule or relevant clinical adverse events were identified posttreatment.

CONCLUSIONS

Laser, radiofrequency, and promestriene delivered comparable, significant symptom improvements among women with breast cancer receiving adjuvant therapy. These treatments did not cause structural tissue damage or other clinical complications.

Laser and radiofrequency for treating genitourinary syndrome of menopause in breast cancer survivors: a systematic review and meta-analysis protocol

INTRODUCTION

Breast cancer survivors (BCSs) experience more severe symptoms of genitourinary syndrome of menopause (GSM) than healthy postmenopausal women. As hormonal therapy with oestrogen should be avoided in BCSs, finding an effective and safe therapy to address vaginal symptoms and sexual dysfunction is urgently needed. Physical methods may be promising alternatives for the specificities of this group of women. This review aims to evaluate the efficacy and safety of physical methods (laser and radiofrequency) for treating GSM in BCSs.

METHODS AND ANALYSIS

The PubMed, Embase, Web of Science, SciELO, LILACS, Scopus, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov databases will be searched. A search strategy was developed to retrieve clinical trials that evaluate the efficacy and safety of any physical method (laser or radiofrequency) used for GSM in BCSs. No date or language restrictions will be imposed. Two authors will independently select studies by title, abstract and full text to meet the inclusion criteria. Data will be extracted, and the risk of bias will be evaluated using the Cochrane risk-of-bias tool (RoB 2). Review Manager 5.4.1 will be used for data synthesis. The Grading of Recommendations, Assessment, Development and Evaluation will be used to assess the strength of the evidence.

ETHICS AND DISSEMINATION

This study reviews the published data; thus, obtaining ethical approval is unnecessary. The findings of this systematic review will be published in a peer-reviewed journal.

Promoting sexual health in older adults: Findings from two rapid reviews

BACKGROUND

Sexual health throughout the life course is increasingly recognised as important to maintaining one's overall health, wellbeing, and relationships. We aimed to provide an overview of the evidence on sexual health needs and sexual health promotion in later life.

METHODS

We undertook two rapid reviews, drawing on systematic review evidence. Searches were conducted in Epistemonikos. Studies were eligible if they reported evidence about the sexual health needs of, or sexual health promotion interventions for, people aged 50+ years. Evidence was quality assessed and summarised in a narrative synthesis.

RESULTS

Fifteen systematic reviews were included in Review 1 (sexual health needs) and 12 in Review 2 (interventions). Key concerns and needs of older adults included the impacts of cultural stigma/misperceptions, barriers to sexual expression, and a need for tailored support in a welcoming environment. Key concerns and needs of health and social care professionals included mixed attitudes towards and knowledge of later-life sexuality and a need for more training and education. Approaches to promoting sexual health in later life included training and workshops for care home professionals, education for older people at risk of/living with HIV, and interventions to address sexual health-related symptoms of menopause. Gaps in the evidence from current reviews and methodological issues in primary studies were identified.

CONCLUSION

Older people have specific needs relating to their sexual health. Health and social care professionals working with older people may benefit from education/training around sexuality in later life. Evidence on effective interventions and strategies is limited.

Microablative fractional radiofrequency for sexual dysfunction and vaginal Trophism: A randomized clinical trial

OBJECTIVES

To evaluate Microablative Fractional Radiofrequency (MAFRF) as a possible option in treating vaginal atrophy.

METHODS

This was a randomized, controlled clinical trial with postmenopausal women diagnosed with vaginal atrophy. The treatment consisted of three sessions of MAFRF, compared to vaginal estrogen administration and an untreated control group. Assessments occurred at baseline and 90 days. The primary endpoints were sexual function, evaluated by the Female Sexual Function Index (FSFI), and vaginal health, assessed by the Vaginal Health Index (VHI). Secondary outcomes included vaginal microbiota composition (Nugent score) and epithelial cell maturation (Maturation Value ‒ MV).

RESULTS

One hundred and twenty women (40 in each group) were included. Concerning the FSFI, both groups, MAFRF (median 4.8 [3.6‒6.0]) and vaginal estrogen (mean 4.7 ± 1.1), experienced improved sexual desire when compared to the control group (median 3.6 [2.4‒4.8]). Regarding the total score of VHI, the authors observed an improvement in the mean of the MAFRF (23.7 ± 2.0) and vaginal estrogen groups (23.5 ± 1.9) when compared to the control (14.8 ± 2.9). The Nugent score was reduced in the MAFRF and estrogen groups (p < 0.01) compared to the control group. Lastly, the MV was modified after treatment with MAFRF (p < 0.01) and vaginal estrogen (p < 0.001). No differences existed between the MAFRF and vaginal estrogen groups in the studied variables. No adverse effects were reported following the MAFRF protocol.

CONCLUSIONS

Radiofrequency was comparable in efficacy to estrogen administration for treating vulvovaginal atrophy. It deserves consideration as a viable option in managing this condition.

Efficacy of a Diode Vaginal Laser in the Treatment of the Genitourinary Syndrome of Menopause

INTRODUCTION

Genitourinary syndrome of menopause (GSM) and vulvovaginal atrophy (VVA) are the most frequent menopause-related clinical entities and are consistently included in the definition of pelvic floor disorders (PFDs). Nonhormonal therapies, such as lubricants and moisturizers, are indicated as first-line treatments, while the "gold standard'' is represented by topical estrogen products; however, in cancer survivors hormonal treatment is not indicated. For this reason, energy-based therapeutic approaches-for instance, through laser technologies-may be employed as alternative options in this kind of patient; however, there are no studies evaluating the efficacy of a pure diode vaginal laser in the treatment of GSM. As a consequence, with our study, we aimed to evaluate outpatient nonablative diode laser treatment in sexually active women, with contraindications, no response, or refusal of local estrogenic therapy.

METHODS

This prospective study included patients with GSM, aged ≥ 18 years old, with contraindications, or refusal of local estrogen therapies. Women were evaluated via the use of their Vaginal Health Index (VHI) scores, which consists of five measures: elasticity, fluid volume, pH, epithelial integrity, and moisture. Moreover, the intensity of VVA symptoms (vaginal burning, vaginal itching, vaginal dryness, dyspareunia, and dysuria) was measured using a 10 cm visual analog scale (VAS), where the left extreme of the scale (score = 0) indicated "absence of symptom" and the right indicated "symptom as bad as it could be" (score = 100). Sexual function was evaluated with the Female Sexual Function Index (FSFI-19) questionnaire. The treatment was performed using a Leonardo Dual diode laser (Biolitec Italia Srl, Milano, Italy). The laser treatment consisted of three sessions, one per month. One month after the third session, the VHI, symptom VAS, and FSFI-19 were re-evaluated. In addition, the Patient Global Impression of Improvement (PGI-I) questionnaire was collected.

RESULTS

Our study enrolled a total of 26 consecutive patients. All patients were either in menopause or under treatment with gonadotropin-releasing hormone (GnRH). None of the patients reported adverse effects after laser treatment. In total, 19 (73.1%) patients referred improvements of their symptoms according to PGI-I scores. All domains of the FSFI-19 questionnaire, significantly improved after the diode laser treatment. The mean VHI score increased by 3.2 points, from 12.2 to 15.4 (p < 0.001). Additionally, we documented a significant improvement in symptoms affecting the VAS score, from 69.2 to 43.5 points (p < 0.001).

CONCLUSION

A diode vaginal laser is an effective and easily tolerated ambulatory procedure for vaginal functional restoration in the treatment of GSM and VVA.

Efficacy and safety of carbon dioxide laser therapy compared with sham for genitourinary syndrome of menopause management: a meta-analysis of randomized clinical trials

IMPORTANCE

Data on whether the carbon dioxide (CO 2 ) laser is useful for treatment of genitourinary syndrome of menopause (GSM) are inconsistent.

OBJECTIVE

This meta-analysis evaluated the benefits and safety of CO 2 laser compared with sham treatment of GSM.

EVIDENCE REVIEW

A relevant literature search of Europe PMC, MEDLINE, Scopus, and ClinicalTrials.gov databases using specific keywords was conducted. The results of continuous variables were pooled into the standardized mean difference (SMD), whereas dichotomous variables were pooled into odds ratio with 95% confidence intervals (95% CI) using random-effects models. A funnel plot was used to assess for the presence of publication bias.

FINDINGS

A total of six randomized clinical trials were included. Pooled analysis revealed that CO 2 laser therapy was associated with a higher reduction in the Vaginal Assessment Scale (SMD, -0.81 [95% CI, -1.59 to -0.04]; P = 0.04; I2 = 88%) and Urinary Distress Inventory short form (SMD, -0.45 [95% CI, -0.84 to -0.06]; P = 0.02; I2 = 0%), and greater patient satisfaction rate (odds ratio, 5.46 [95% CI, 2.23 to 13.37]; P = 0.0002; I2 = 0%) when compared with sham-only treatment. Meanwhile, the Female Sexual Function Index, Vaginal Health Index, and Patient Global Impression Improvement did not differ significantly between groups. Adverse events were only mild with no serious adverse events reported.

CONCLUSIONS AND RELEVANCE

CO 2 laser therapy may improve the overall treatment of GSM with a relatively good safety profile. However, further randomized clinical trials with larger sample sizes are still needed to confirm the results of this study.

A practical guide to managing genitourinary syndrome of menopause in primary care

ABSTRACT

Females spend a third to half of their life in menopause, and the number of US females in menopause is growing. A high percentage of postmenopausal females experience bothersome, sometimes debilitating genitourinary symptoms, which can affect quality of life. The genitourinary syndrome of menopause (GSM) describes the condition previously referred to as vulvovaginal atrophy, atrophic vaginitis, or urogenital atrophy. Of concern, many patients with symptoms of GSM have never been asked about nor have they initiated conversations about these concerns with a healthcare provider. This article addresses the need to improve screening, identification, and patient-centered management in primary care of females with GSM.

Effects of Non-Ablative Solid-State Vaginal Laser (SSVL) for the Treatment of Vulvovaginal Atrophy in Breast Cancer Survivors after Adjuvant Aromatase Inhibitor Therapy: Preliminary Results

BACKGROUND

One of the side effects of anti-estrogen treatments in breast cancer survivors (BCSs), especially with aromatase inhibitor (AI) treatment, is the frequent appearance of vulvo-vaginal atrophy (VVA). We aim to evaluate the efficacy, safety and feasibility of a new type of non-ablative Solid-State Vaginal Laser (SSVL) treatment in BCSs with VVA.

METHODS

A total of 30 BCSs with a history of AI use and symptoms of VVA were treated with a non-ablative SSVL (LASEmaR 1500™-EUFOTON)in this non-randomized pilot study. The effects of the laser have been evaluated at baseline, 10 wk and 24 wk using a visual analogue scale (VAS), the Vaginal Health Index (VHI), the Vulvar Health Index (VuHI), the Female Sexual Function Index (FSFI), the EORTC QLQ-BR23, the Vaginal Maturation Index (VMI) and vaginal pH.

RESULTS

At 10-week follow-up vs. baseline there were no statistically significant differences in FSFI, lubrication and EORTC QLQ-BR23. In all the subjective (dyspareunia, VHI, VuHI, FSFI, QLQ) and objective parameters (VMI and pH) there was a statistically significant improvement at the 6-month follow-up. Satisfaction was very high (4.7 out of 5), with 95.7% of patients being satisfied, more than or very satisfied.

CONCLUSIONS

Preliminary results of SSVL treatment of VVA and dyspareunia in BCSs after AI treatment suggest clinical improvement, without relevant side effects and with a high degree of satisfaction.

The Impact of Systemic Sclerosis on Sexual Health: An Italian Survey

OBJECTIVE

To evaluate the impact of systemic sclerosis (SSc) on vulvovaginal atrophy (VVA) and sexual health in an Italian population.

METHODS

An Italian survey about the prevalence and severity of VVA (on a 0 to 10 scale) and sexual dysfunction (using the Female Sexual Function Index-FSFI) through an anonymous online questionnaire. We investigated couple relationships and intimacy with partners, the predisposition of patients to talk about their sexual problems, physicians' receptivity, and treatment scenarios. Risk factors for VVA symptoms and sexual dysfunction were assessed.

RESULTS

A total of 107 women affected by SSc were enrolled. Of these, 83.2% of women (89/107) complained about VVA symptoms and 89.7% (among sexually active women; 87/97) about sexual dysfunction. Menopausal status did not affect VVA symptoms, while age was the only independent risk factor for sexual dysfunction. About 70% (74/107) of women reported a negative impact of disturbances on intimacy with their partner. A total of 63 women (58.9%) had never discussed their sexual problems and VVA condition with a physician. Lubricants were the only treatment prescribed, and 75% of women would welcome new therapies, even if experimental (62.9%).

CONCLUSIONS

In women with SSc, VVA symptoms and sexual dysfunction are highly prevalent, independently from menopause. In more than half of the investigated women with SSc, we found reluctance to talk about their sexual problems, despite being symptomatic. This should encourage physicians to investigate vulvovaginal and sexual health. SSc patients would welcome the advent of new treatment possibilities for their VVA and sexual complaints.

Genitourinary Syndrome of Menopause in Breast Cancer Survivors: Current Perspectives on the Role of Laser Therapy

Genitourinary syndrome of menopause (GSM) is a frequent consequence of iatrogenic menopause or anti-estrogenic adjuvant therapies in breast cancer survivors (BCSs). GSM may profoundly affect sexual health and quality of life, and a multidimensional unique model of care is needed to address the burden of this chronic heterogeneous condition. Severe symptoms may be insufficiently managed with non-hormonal traditional treatments, such as moisturizers and lubricants, recommended as the first-line approach by current guidelines, because concerns exist around the use of vaginal estrogens, particularly in women on aromatase inhibitors (AIs). Vaginal laser therapy has emerged as a promising alternative in women with GSM who are not suitable or do not respond to hormonal management, or are not willing to use pharmacological strategies. We aim to systematically review current evidence about vaginal laser efficacy and safety in BCSs and to highlight gaps in the literature. We analyzed results from 20 studies, including over 700 BCSs treated with either CO2 or erbium laser, with quite heterogeneous primary outcomes and duration of follow up (4 weeks-24 months). Although evidence for laser efficacy in BCSs comes mostly from single-arm prospective studies, with only one randomized double-blind sham-controlled trial for CO2 laser and one randomized comparative trial of erbium laser and hyaluronic acid, available data are reassuring in the short term and indicate effectiveness of both CO2 and erbium lasers on the most common GSM symptoms. However, further studies are mandatory to establish long-term efficacy and safety in menopausal women, including BCSs.

Vaginal laser therapy for GSM/VVA: where we stand now - a review by the EUGA Working Group on Laser

Vulvovaginal atrophy (VVA) is a chronic progressive condition that involves the genital and lower urinary tracts, related to the decrease of serum estrogenic levels when menopause occurs. The definition of genitourinary syndrome of menopause (GSM) is a medically more accurate, all-encompassing and publicly acceptable term than VVA. Due to the chronic progressive trend of GSM, symptoms tend to reappear after the cessation of therapy, and frequently long-term treatment is required. First-line therapies include vulvar and vaginal lubricant or moisturizers, and, in the case of failure, low-dose vaginal estrogens are the preferred pharmacological therapy. Populations of patients, such as breast cancer (BC) survivors, are affected by iatrogenic GSM symptoms with concerns about the use of hormonal therapies. The non-ablative erbium:YAG laser and the fractional microablative CO2 vaginal laser are the two main lasers evaluated for GSM treatment. The aim of this comprehensive review is to report the efficacy and safety of Er:YAG and CO2 vaginal lasers for GSM treatment. Vaginal laser therapy has been demonstrated to be effective in restoring vaginal health, improving VVA symptoms and sexual function. The data suggest that both Er:YAG and CO2 vaginal lasers are safe energy-based therapeutic options for management of VVA and/or GSM symptoms in postmenopausal women and BC survivors.

Efficacy of Fractional CO2 Laser Treatment for Genitourinary Syndrome of Menopause in Short-Term Evaluation-Preliminary Study

The postmenopausal state covers 40% of modern women's lives and 50-70% of postmenopausal women report GSM symptoms such as vaginal dryness, itching, frequent inflammations, lack of elasticity, or dyspareunia. Consequently, a safe and effective method of treatment is crucial. In a group of 125 patients, a prospective observational study was performed. The aim was to evaluate the clinical effectiveness of fractional CO₂ laser in the treatment of GSM symptoms using a protocol of three procedures in 6-week intervals. The vaginal pH, VHIS, VMI, FSFI, and treatment satisfaction questionnaire were used. The fractional CO₂ laser treatment was effective in improving all the objective forms of evaluation: vaginal pH (from 5.61 ± 0.50 at the baseline up to 4.69 ± 0.21 in the 6-week follow-up after the third procedure); VHIS (12.02 ± 1.89 at the baseline vs. 21.50 ± 1.76); VMI (21.5 ± 5.66 vs. 48.4 ± 4.46). Similar results were obtained for FSFI: 12.79 ± 5.351 vs. 24.39 ± 2.733, where 79.77% of patients were highly satisfied. Fractional CO₂ laser therapy increases the quality of life by having a beneficial effect on the sexual function of women with GSM symptoms. This effect is obtained by restoring the correct structure and proportions of the cellular composition of the vaginal epithelium. This positive effect was confirmed by both objective and subjective forms of evaluating GSM symptom severity.

Therapeutic Choices for Genitourinary Syndrome of Menopause (GSM) in Breast Cancer Survivors: A Systematic Review and Update

(1) Background: Genitourinary syndrome of menopause (GSM) is a medical condition that can affect breast cancer survivors (BCS). This is a complication that often can occur as a result of breast cancer treatment, causing symptoms such as vaginal dryness, itching, burning, dyspareunia, dysuria, pain, discomfort, and impairment of sexual function. BCS who experience these symptoms negatively impact multiple aspects of their quality of life to the point that some of them fail to complete adjuvant hormonal treatment; (2) Methods: In this systematic review of the literature, we have analyzed possible pharmacological and non-pharmacological treatments for GSM in BCS. We reviewed systemic hormone therapy, local hormone treatment with estrogens and androgens, the use of vaginal moisturizers and lubricants, ospemifene, and physical therapies such as radiofrequency, electroporation, and vaginal laser; (3) Results: The data available to date demonstrate that the aforementioned treatments are effective for the therapy of GSM and, in particular, vulvovaginal atrophy in BCS. Where possible, combination therapy often appears more useful than using a single line of treatment; (4) Conclusions: We analyzed the efficacy and safety data of each of these options for the treatment of GSM in BCS, emphasizing how often larger clinical trials with longer follow-ups are needed.

Safety and efficacy of fractional CO2 laser treatment to the vestibule: a randomized, double-blind, sham-controlled, prospective 3-site clinical study in women with vestibular pain

BACKGROUND

Data are limited regarding fractional CO2 laser as a nonhormonal treatment for vestibular pain.

AIM

We sought to perform what is, to our knowledge, the first multisite prospective randomized, double-blind, sham-controlled clinical trial to assess the safety and efficacy of fractional CO2 laser treatment to the vestibule in women with vestibular pain.

METHODS

Subjects (n = 70) meeting inclusion/exclusion criteria at each of 3 sites were randomized 2:1 to active or sham (zero energy) fractional CO2 laser treatment using the vestibular probe (SmartXide2 V2LR - MonaLisa Touch, DEKA, Florence, Italy). Subjects in each treatment arm received 3 treatments 4 weeks apart. At the initial follow-up (week 12), subjects were unblinded and those initially assigned to sham started active treatment.

OUTCOMES

Outcome measures included changes from baseline in sexual activity diaries and scores for the Vulvoscopic Genital Tissue Appearance Scale (VGTA), vestibular cotton-tipped swab testing, McGill Pain Questionnaire, Female Sexual Function Index (FSFI), Female Sexual Distress Scale-Revised (FSDS-R), and the O'Leary-Sant voiding and pain indices, the Interstitial Cystitis Symptom Index (ICSI) and Interstitial Cystitis Problem Index (ICPI).

RESULTS

After active treatment, VGTA scores significantly improved in 5 parameters. Pain associated with cotton-tipped swab testing was significantly reduced at weeks 4 through 16 (mean change from baseline -0.64 [95% CI, -0.79 to -0.50] and -1.31 [95% CI, -1.46 to -1.16], respectively). FSFI pain domain scores improved significantly at weeks 12 and 16 (mean change from baseline 0.925 [95% CI, 0.10-1.75] and 1.22 [95% CI, 0.40-2.05], respectively). FSFI total scores increased significantly at weeks 12 and 16 (mean change from baseline 6.24 [95% CI, 2.64-9.85] and 4.96 [95% CI, 1.36-8.57], respectively). FSDS-R scores decreased significantly at weeks 12 and 16 (mean change from baseline -5.84 [95% CI, -8.80 to -2.87] and -9.15 [95% CI, -12.11 to -6.18], respectively). ICSI scores decreased significantly at weeks 12 and 16 (mean change from baseline -0.91 [95% CI, -1.65 to -0.18] and -0.754 [95% CI, -1.49 to -0.02], respectively). ICPI scores decreased significantly at week 16 (mean change from baseline -0.99 [95% CI, -1.63 to -0.34]). In contrast, there were no significant changes in outcomes in the sham arm. No serious adverse events occurred.

CLINICAL IMPLICATIONS

Fractional CO2 laser treatment in women with vestibular pain resulted in improvement from baseline in multiple key outcome measures of vestibular health.

STRENGTHS AND LIMITATIONS

Strengths of the study were that it was a multisite prospective randomized double-blind, sham-controlled clinical trial that included multiple measures related to vestibular pain and sexual function. Limitations were the nonvalidated primary outcome measure and limited study cohort.

CONCLUSION

Fractional CO2 laser therapy is a safe and effective nonhormonal treatment for vestibular pain.

Superficial dyspareunia treatment with hyperstacking of erbium:yttrium-aluminum-garnet SMOOTH laser: a short-term, pilot study in breast cancer survivors

OBJECTIVE

This prospective pilot study aimed to evaluate the effects of a modified vaginal erbium laser (VEL) protocol, using the hyperstack mode on the vaginal vestibulum and introitus to treat superficial dyspareunia in postmenopausal breast cancer survivors suffering from the genitourinary syndrome of menopause.

METHODS

In this pilot, prospective, randomized study, two groups of postmenopausal women suffering from superficial dyspareunia were included: 34 women (VEL group) were treated with erbium laser crystal yttrium-aluminum-garnet (XS Fotona SMOOTH; Fotona, Ljubljana, Slovenia) with a wavelength of 2,940 nm; for the other 34 (hyperstack group), a modified second step of the VEL protocol for the treatment of vestibulum and introitus was used, with hyperstacked (repeating a number of) subablative, long pulses with very low fluences. For each group, three laser applications at 30-day intervals were performed. Symptoms were assessed before, after each application, and after 1 and 3 months from the last laser application, using the visual analog scale score for superficial dyspareunia.

RESULTS

Superficial dyspareunia improved in both groups over time (P < 0.001), regardless of age and years since menopause status. The reduction in visual analog scale score after the third laser application was 58% in VEL versus 73.5% in hyperstack. The hyperstack group, since the first laser application, showed a greater (P < 0.001) and persistent improvement of superficial dyspareunia.

CONCLUSIONS

The hyperstack treatment of the introitus and vestibulum in breast cancer survivors leads to a more significant improvement in superficial dyspareunia than the VEL alone.

CO2 laser therapy for management of stress urinary incontinence in women: a systematic review and meta-analysis

Background

Carbon dioxide (CO2) laser therapy is an emerging treatment for women with stress urinary incontinence (SUI).

Objectives

To examine the efficacy of CO2 laser therapy for management of SUI-related symptoms in women.

Design

A systematic review and meta-analysis of randomized controlled trials and cohort studies.

Data sources and methods

Four databases were screened until January 2023. All efficacy continuous endpoints were assessed via subtraction of the posttreatment from pretreatment values. The data were summarized as mean difference (MD) with 95% confidence interval (CI) using the random-effects model.

Results

A total of 15 studies with 700 patients were analyzed. CO2 laser therapy significantly decreased the 1-h pad weights at 3 months [n = 5 studies, MD = -3.656 g, 95% CI (-5.198, -2.113), p < 0.001], 6 months [n = 6 studies, MD = -6.583 g, 95% CI (-11.158, -2.008), p = 0.005], and 12 months [n = 6 studies, MD = -3.726 g, 95% CI (-6.347, -1.106), p = 0.005]. Moreover, CO2 laser therapy significantly decreased the International Consultation of Incontinence Questionnaire-Urinary Incontinence Short Form Scores at 3 months [n = 10 studies, MD = -4.805, 95% CI (-5.985, -3.626), p < 0.001] and 12-months [n = 6 studies, MD = -3.726, 95% CI (-6.347, -1.106), p = 0.005]. Additionally, CO2 laser therapy significantly decreased the Pelvic Floor Impact Questionnaire scores at 6 months [n = 2 studies, MD = -11.268, 95% CI (-18.671, -3.865), p = 0.002] and 12 months [n = 2 studies, MD = -10.624, 95% CI (-18.145, -3.103), p = 0.006]. Besides, CO2 laser therapy significantly decreased the Urogenital Distress Inventory-6 scores at 3 months [n = 2 studies, MD = -21.997, 95% CI (-32.294, -11.699), p < 0.001], but not at 6 months [n = 3 studies, MD = -3.034, 95% CI (-7.357, 1.259), p = 0.169]. Lastly, CO2 laser therapy significantly increased the Vaginal Health Index Score at 6 months [n = 2 studies, MD = 2.826, 95% CI (0.013, 5.638), p = 0.047] and 12 months [MD = 1.553, 95% CI (0.173, 2.934), p = 0.027].

Conclusion

CO2 laser therapy improved the SUI-related symptoms in women. To obtain solid conclusions, future studies should be well-designed with standardized settings, consistent therapeutic protocols, and long-term follow-up periods.

New Innovations for the Treatment of Vulvovaginal Atrophy: An Up-to-Date Review

Vulvovaginal atrophy (VVA) is a chronic progressive disease involving the female genital apparatus and lower urinary tract. This condition is related to hypoestrogenism consequent to menopause onset but is also due to the hormonal decrease after adjuvant therapy for patients affected by breast cancer. Considering the high prevalence of VVA and the expected growth of this condition due to the increase in the average age of the female population, it is easy to understand its significant social impact. VVA causes uncomfortable disorders, such as vaginal dryness, itching, burning, and dyspareunia, and requires constant treatment, on cessation of which symptoms tend to reappear. The currently available therapies include vaginal lubricants and moisturizers, vaginal estrogens and dehydroepiandrosterone (DHEA), systemic hormone therapy, and Ospemifene. Considering, however, that such therapies have some problems that include contraindications, ineffectiveness, and low compliance, finding an innovative, effective, and safe treatment is crucial. The present data suggest great efficacy and safety of a vaginal laser in the treatment of genital symptoms and improvement in sexual function in patients affected by VVA. The beneficial effect tends to be sustained over the long-term, and no serious adverse events have been identified. The aim of this review is to report up-to-date efficacy and safety data of laser energy devices, in particular the microablative fractional carbon dioxide laser and the non-ablative photothermal Erbium-YAG laser.

Vaginal Laser Therapy for Female Stress Urinary Incontinence: New Solutions for a Well-Known Issue-A Concise Review

Background and Objectives: Insufficient connective urethra and bladder support related to childbirth and menopausal estrogen decrease leads to stress urinary incontinence (SUI). The aim of this review is to narratively report the efficacy and safety of new mini-invasive solutions for SUI treatment as laser energy devices, in particular, the microablative fractional carbon dioxide laser and the non-ablative Erbium-YAG laser. Materials and Methods: For this narrative review, a search of literature from PubMed and EMBASE was performed to evaluate the relevant studies and was limited to English language articles, published from January 2015 to February 2022. Results: A significant subjective improvement, assessed by the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-UI-SF) was reported at the 6-month follow up, with a cure rate ranged from 21% to 38%. A reduction of effect was evidenced between 6 and 24-36 months. Additionally, the 1-h pad weight test evidence a significant objective improvement at the 2-6-month follow up. Conclusions: SUI after vaginal laser therapy resulted statistically improved in almost all studies at short-term follow up, resulting a safe and feasible option in mild SUI. However, cure rates were low, longer-term data actually lacks and the high heterogeneity of methods limits the general recommendations. Larger RCTs evaluating long-term effects are required.
