Clinical evaluation of autologous platelet rich plasma injection in post menopausal vulvovaginal atrophy; A pilot study

Vulvovaginal Atrophy Following Treatment for Oncogynecologic Pathologies: Etiology, Epidemiology, Diagnosis, and Treatment Options

Vulvovaginal atrophy, characterized by the thinning of vaginal mucosa typically resulting from reduced estrogen levels, is frequently exacerbated by oncogynecologic treatments such as chemotherapy, hormonal therapy, radiotherapy, or surgery. This condition significantly impacts the quality of life for cancer survivors, leading to persistent discomfort, heightened infection risk, and negative effects on sexual function and self-esteem. Despite being a relatively common complication, vulvovaginal atrophy is not always discussed before the start of treatment. Treatments typically mirror those used for natural menopause; however, efficacy and safety data specific to this population are limited due to the exclusion of these patients from clinical trials. A major safety concern is the risk of hormone-sensitive cancer recurrence associated with estrogen therapy, which drives a preference for non-hormonal alternatives. Newer treatments, such as laser therapy, radiofrequency, and vaginal injections, show promise with minimal side effects and hormone-independent mechanisms, though efficacy data varies, highlighting the need for further research. This narrative review explores the epidemiology, risk factors, diagnosis, and management of vulvovaginal atrophy after the treatment for oncogynecologic disorders.

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.

Role of Platelet-Rich Plasma in Genitourinary Syndrome of Menopause

The genitourinary syndrome of menopause (GSM) encompasses a range of symptoms linked to the genitourinary tract stemming from the reduction in estrogen levels following menopause. These symptoms may endure throughout a woman's lifetime. Platelet-rich plasma (PRP), known for its capacity to induce angiogenesis and the restoration effects of growth factors, has been widely employed in various disorders, including GSM. This article aims to comprehensively review the existing literature on the utilization of PRP for managing GSM. The search was executed in electronic databases, specifically PubMed, Scopus, and Google Scholar, up until April 2023. Eligible studies were meticulously chosen for inclusion in this systematic review. PRP emerges as a viable alternative for addressing vaginal atrophy, exhibiting favorable outcomes. Notably, it can be considered for patients with contraindications to hormonal therapy. However, the available body of evidence supporting the use of PRP for GSM remains limited. PRP presents itself as a promising agent, offering a patient-friendly, cost-effective alternative modality. To establish the efficacy of PRP in treating GSM definitively, future randomized trials are imperative.

Injection Treatments for Vulvovaginal Atrophy of Menopause: A Systematic Review

BACKGROUND

Injection treatments have been proposed as novel treatment options for Vulvovaginal Atrophy of Menopause (VVA) also known as Genitourinary Syndrome of Menopause (GSM). However, to date data about these treatments are poor.

OBJECTIVE

To assess all available injection treatments for VVA.

METHODS

A systematic review was performed by searching five electronic databases for peer-reviewed studies that assessed injection treatments for VVA.

RESULTS

Eight studies (7 observational and 1 randomized) with 236 women were included. Assessed injection materials were: autologous platelet-rich plasma (PRP) + hyaluronic acid (HA), not cross-linked HA plus calcium hydroxyapatite (NCLHA + CaHA), micro-fragmented adipose tissue (MFAT), hyaluronan hybrid cooperative complexes (HCC), crosslinked HA, microfat and nanofat grafting + PRP, and PRP alone. Improvement in GSM symptoms after treatment was assessed through Visual Analogic Scale (VAS) for GSM symptoms or patient satisfaction, several validated questionnaires (FSFI, VHI, FSD, SF12, ICIQ UI SF, PGI-I, FSDS-R, VSQ), symptoms severity, changes in vaginal mucosa thickness, flora, pH, and expression on vaginal mucosal biopsies of Procollagen I and III and ki67 immunofluorescence or COL1A1 and COL3A1 mRNA. Injection treatments showing significant improvement in GSM-related symptoms were: (i) HCC in terms of VAS for GSM symptoms and FSFI score; (ii) Crosslinked HA in terms of VAS for GSM symptoms, FSFI and VHI score, COL1A1 and COL3A1 mRNA expression on vaginal mucosal biopsies; (iii) NCLHA + CaHA in terms of FSFI score; (iv) PRP + HA in terms of VHI, FSD and SF12 score; (v) microfat and nanofat grafting + PRP in terms of VHI score and FSDS-R score; (vi) PRP alone in terms of VHI and VSQ scores.

CONCLUSIONS

All assessed injection treatments except for MFAT seem to lead to significant improvement in VVA symptoms on validated questionnaires. Further studies are necessary in the field.

Efficacy and Safety of Platelet-Rich Plasma Injections for the Treatment of Female Sexual Dysfunction and Stress Urinary Incontinence: A Systematic Review

Introduction: There is no clear evidence in the literature that platelet-rich plasma (PRP) injections improve female sexual dysfunction (FSD) and female stress urinary incontinence (SUI). Objectives: A systematic review was performed to study the efficacy and safety of PRP injections in women with the above pathologies, as well as to explore the optimal dosing, frequency and area of injections, and duration of treatment. Methods: A systematic search on PubMed, Embase and the Cochrane Library database was performed, as well as sources of grey literature from the date of database or source creation to January 2023. After title/abstract and full-text screening, clinical studies on humans evaluating the efficacy of PRP in gynecological disorders using standardized tools were included. Risk of bias was undertaken with RoB-2 for randomized-controlled trials (RCT) and the Newcastle-Ottawa Scale (NOS) for observational studies. Results: Four prospective and one retrospective study explored FSD, while six prospective and one RCT evaluated female SUI. A total of 327 women with a mean age of 51 ± 12 years were included. For FSD, PRP significantly improved the Female Sexual Function Index (FSFI), the Vaginal Health Index (VHI) and the Female Sexual Distress score (FSDS). For SUI, PRP led to a significant improvement in the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and the Urogenital Distress Inventory (UDI-6). The identified RCT reported a significantly higher mean score of ICIQ-SF (p < 0.05) and UDI-6 (p < 0.01) in the midurethral sling group compared to the PRP injections group. Regarding the risk of bias, the RCT was characterized by high risk, whereas the observational studies were of moderate risk. The protocol for PRP injections for FSD is the injection of 2 mL of PRP into the distal anterior vaginal wall once a month for 3 months. For female SUI, 5-6 mL of PRP should be injected into the periurethral area once a month for 3 months. Conclusions: Despite the promising initial results of PRP injections, the level of current evidence is low due to methodological issues in the available studies. It becomes clear that there is an emerging need for high-quality research examining PRP injections for the treatment of FSD and female SUI.

Comparable Efficacy of Submucosal Platelet-Rich Plasma and Combined Platelet-Rich Plasma Noncrosslinked Hyaluronic Acid Injections in Vulvovaginal Atrophy: A Cancer Survivorship Issue

Background: Cancer survivors are often reluctant to discuss sexual complaints with their oncologists and treatment is frequently unsatisfactory due to paucity of controlled studies and inapplicability of vaginal estrogen. We aimed to evaluate efficacy and tolerability of platelet-rich plasma (PRP) injections alone or in combination with noncrosslinked hyaluronic acid compared with standard therapy with topical hyaluronic acid gel in the management of cancer therapy-induced or aggravated vulvovaginal atrophy. Materials and Methods: This prospective, parallel-group comparative study was conducted on 45 female patients with a history of cancer and complaining of symptoms of vulvovaginal atrophy either induced or aggravated by cancer treatment. Patients were randomly divided into three groups (A, B, and C). Group A patients received two submucosal vaginal PRP injections, group B patients received two similar injections of PRP combined with noncrosslinked hyaluronic acid, and group C received a topical vaginal hyaluronic acid gel applied three times weekly for 2 months. Main outcome measures were vulvovaginal atrophy symptom severity and vaginal health index (VHI) scores before treatment (v0), 1 month from baseline (v1), 2 months from baseline (v2), and 3 months after the last visit (v3). Results: Both groups A and B showed greater improvement of frequency of intercourse avoidance than group C. Group A showed greater improvement of dyspareunia than group C. Groups A and B demonstrated greater improvement of vaginal pH, fluid volume, and total VHI scores than group C. Short-term topical hyaluronic acid (HA) was not associated with any significant improvement of vaginal elasticity. Group B showed greater improvement of vaginal dryness and moisture scores than group C. Reported adverse events were injection-related pain in all patients of groups A and B and vaginal spotting in groups A and B. Conclusion: Both PRP and PRP-HA have comparable efficacy and patient-reported treatment satisfaction. PRP injections were better tolerated by patients than PRP-HA. Clinical trial registration number: NCT05782920.

Platelet rich plasma for the management of urogynecological disorders: the current evidence

PURPOSE OF REVIEW

Our objective is to review the currently available literature on the use of platelet-rich plasma (PRP) in patients with pelvic floor disorders and to critically appraise the latest evidence on the safety and efficacy of the PRP application.

RECENT FINDINGS

The evidence on the use of PRP for the treatment of stress urinary incontinence (SUI) appears promising, although limited to case series, case reports and animal studies. PRP has also been proposed to enhance the surgical outcomes of pelvic organ prolapse (POP) by native tissue repair with promising success rates. The application of PRP in other PFDs including vaginal fistulas, genitourinary syndrome of menopause (GSM), mesh exposure and lichen sclerosus has been also associated with beneficial outcomes and a favorable safety profile.

SUMMARY

The currently available literature indicates that PRP could have a beneficial effect as a single or adjuvant treatment in patients with SUI, POP, GSM, vaginal fistula and genital lichen sclerosus with minimal adverse events. However, valid evidence is still lacking and further well-designed studies are warranted in the field to confirm the validity of the so far reported outcomes.
