The efficacy of medical management of leiomyoma-associated heavy menstrual bleeding: a mini review.

Leiomyomas, or fibroids, are benign uterine tumors that are commonly associated with abnormal uterine bleeding-L particularly heavy menstrual bleeding (HMB). Treatment options include expectant, medical, image-guided, and surgical. Medical management of HMB is the preferred first-line treatment and includes nonsteroidal anti-inflammatory drugs, contraceptive hormones, tranexamic acid, levonorgestrel intrauterine system, gonadotropin-releasing hormone (GnRH) antagonists and antagonists, selective progesterone receptor modulators, selective estrogen receptor modulators, and aromatase inhibitors. Although alternatives such as vitamins and supplements have been suggested, there is currently a lack of robust evidence of their efficacy. Many of these therapies treat the symptoms rather than the underlying pathology. Progestin-based therapies are the most commonly utilized, although research supporting their effectiveness in the treatment of HMB is modest. Although GnRH agonists and antagonists, which are federal drug administration-approved therapies, provide substantial improvement in abnormal uterine bleeding-L with HMB, the effects typically last for the duration of therapy. Patients may also face financial barriers to GnRH analog therapy. Future studies are required to delineate the nonhormonal treatment options and the long-term management of leiomyoma-associated HMB.

Epigallocatechin Gallate for the Treatment of Benign and Malignant Gynecological Diseases-Focus on Epigenetic Mechanisms.

The most common malignant gynecologic diseases are cervical, uterine, ovarian, vaginal, and vulvar cancer. Among them, ovarian cancer causes more deaths than any other cancer of the female reproductive system. A great number of women suffer from endometriosis, uterine fibroids (UFs), adenomyosis, dysmenorrhea, and polycystic ovary syndrome (PCOS), which are widespread benign health problems causing troublesome and painful symptoms and significantly impairing the quality of life of affected women, and they are some of the main causes of infertility. In addition to the available surgical and pharmacological options, the effects of supporting standard treatment with naturally occurring compounds, mainly polyphenols, are being studied. Catechins are responsible for the majority of potential health benefits attributed to green tea consumption. Epigallocatechin gallate (EGCG) is considered a non-toxic, natural compound with potential anticancer properties. Antioxidant action is its most common function, but attention is also drawn to its participation in cell division inhibition, apoptosis stimulation and epigenetic regulation. In this narrative review, we describe the role of EGCG consumption in preventing the development of benign reproductive disorders such as UF, endometriosis, and PCOS, as well as malignant gynecologic conditions. We discuss possible epigenetic mechanisms that may be related to the action of EGCG.

A Multimodal Ultrasound Observation Study on the Effect of Vitamin D on Uterine Fibroids in Non-menopausal Women.

INTRODUCTION: It has been reported in the literature that Vitamin D can inhibit the growth of uterine fibroids, but the evaluation index is only the size of the uterine fibroids. The purpose of this study was to evaluate the effect of vitamin D on the size, hardness, and blood flow of uterine fibroids in premenopausal women by multimodal ultrasound. METHODS: A total of 64 pre-menopausal women with uterine fibroids complicated vitamin D deficiency were enrolled in this study and randomly divided into two groups: the vitamin D group (n=32) which received oral vitamin D (1600 IU/ day) and the control group (n=32) without vitamin D supplementation. After three months of intervention, the mean diameter of uterine fibroids, elastic strain ratio, and blood flow grade were evaluated by multimodal ultrasound, and the clinical symptoms of the two groups were evaluated by questionnaire. RESULTS: The vitamin D group reported a significant increment in the serum 25-hydroxyvitamin D (P < 0.001). In addition, there were significant reductions in the mean diameter, and elastic strain ratio of uterine fibroids (P =.043 and P =.038, respectively), but no significant difference in the blood flow grade of uterine fibroids was observed (P =.272). Compared with the control group, the vitamin D group achieved significant relief in dysmenorrhea and frequent urination, as well as improvement in heavy menstrual bleeding. CONCLUSION: The application of multimodal ultrasound provides a more comprehensive theoretical basis for vitamin on uterine fibroids. Vitamin D can effectively reduce the size of uterine fibroids in pre-menopausal women and relieve their symptoms. It is highly likely to be a promising, safe, effective, and inexpensive drug for uterine fibroids, which has good application value and promotion prospects.

Acupuncture combined with mifepristone improves sex hormones and inflammatory factors in patients with uterine fibroids.

OBJECTIVE: To analyze the therapeutic effect of acupuncture combined with mifepristone on uterine fibroids and its influence on sex hormones and inflammatory factors. METHODS: Data of 102 patients with uterine fibroids admitted to Shanxi Provincial Hospital of Chinese Medicine from January 2019 to January 2022 were retrospectively analyzed. Among them, there were 50 patients treated with mifepristone alone (control group) and 52 patients undergoing combined treatment of acupuncture and mifepristone (observation group). After 2 months of continuous treatment, the therapeutic efficacy, volume of uterine fibroids and uterus, levels of inflammatory factors (C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α)), as well as levels of estradiol (E2), follicle-stimulating hormone (FSH) and luteinizing hormone (LH), along with hemodynamic levels and incidence of adverse reactions were recorded and compared between the two groups. Logistic analysis was employed to identify the independent risk factors for the recurrence of uterine fibroids in patients. RESULTS: Compared with the control group, the observation group was identified with significantly higher overall response rate (P < 0.05). The uterine fibroid volume and uterine volume significantly improved in both groups after treatment, and the improvements were more prominent in the observation group than in the control group (P < 0.05). After treatment, the serum CRP and TNF-α were both evidently decreased in the two groups, while levels of E2, FSH, LH and peak blood flow velocity were significantly ameliorated, and the improvements in the observation group were more significant than those in the control group (P < 0.05). There was no significant difference in the incidence of adverse reactions between the two groups (P > 0.05). Alcohol intake and treatment regime were independent risk factors for the recurrence of uterine fibroids in patients. CONCLUSION: Combining acupuncture with mifepristone can significantly improve uterine fibroids, estrogen and progesterone levels, as well as reduce inflammation, with a high level of safety, making it a promising treatment for clinical use.

Prevention of Uterine Fibroids: molecular mechanisms and potential clinical application.

Uterine fibroids (UFs; leiomyoma) are the most common benign neoplastic threat to women worldwide, exacting an immense personal burden on female health and a monetary expense to the healthcare system estimated in the hundreds of billions of dollars every year globally. With no long-term non-invasive treatment option currently available to treat UFs, deeper insights regarding tumor etiology are the key for developing newer therapies. Accordingly, in this review, we discuss new mechanistic paradigm to explain UF tumor development through an exquisite model involving developmental reprogramming of myometrial stem cells due to early life endocrine disruptors exposure, inflammation, fibrosis, DNA damage, and eventually tissue stiffness. Further, we propose to utilize shear wave elastography as a potential screening tool for the early identification of women at risk for developing UFs who can benefit from several simple preventive strategies, including the consumption of natural compounds such as vitamin D and green tea as a safe fertility friendly non-hormonal modality to delay or even arrest or reverse UF progression.

Potential mechanism of Taohong Siwu Decoction in uterine fibroid treatment based on integrated strategy of network pharmacology and experimental verification.

BACKGROUND: Taohong Siwu Decoction (THSWD) is a widely prescribed Traditional Chinese Medicine (TCM) for treating gynecological diseases. It is used to treat uterine fibroids (UF) in China, while its potential therapeutic effects and mechanism are unknown. METHODS: The present study used network pharmacology to identify PI3K/AKT as one of the main THSWD signaling pathways that can be targeted to treat UF. The potential binding sites of miR-21-5p to PTEN were predicted using online databases. We were able to establish a UF rat model successfully. We selected the 15% THSWD serum after preparing THSWD drug-containing serum to culture tumor tissue-derived cells. These studies enabled us to assess the role of THSWD in UF improvement. RESULTS: In vivo, we observed that low, medium, and high doses of THSWD improved histological changes in UF rats by increasing the expression levels of PTEN and miR-21-5p in their uterus while decreasing the expression levels of p-PI3K, p-AKT, and miR-21-5p. Treatment with THSWD medicated serum (15%) effectively inhibited the proliferation of cells derived from human UF and promoted apoptosis in vitro. PI3K phosphorylation, Akt phosphorylation, and miR-21-5p expression were decreased, while PTEN and cleaved caspase-3 were increased. These findings were reversed by administering 740 Y-P (a PI3K/Akt pathway agonist) and a miR-21-5p mimic. In addition, the double luciferase reporter gene assay confirmed the targeted binding relationship between miR-21-5p and PTEN. CONCLUSIONS: THSWD inhibited the expression and activation of the PI3K/AKT and miR-21-5p/PTEN pathways, resulting in anti-UF activity in leiomyoma cell models. Our findings suggest that THSWD could be used to treat UF.

Contemporary approaches in the management of uterine leiomyomas.

BACKGROUND: Leiomyomas (fibroids), the most common benign solid tumours in females, originate from the myometrium and are associated with poor quality of life for patients. The current management of uterine leiomyomas mainly includes surgical interventions such as hysterectomy and myomectomy, either by laparoscopy or laparotomy, which have several complications and are not ideal for preserving fertility. Therefore, there is a need to develop or repurpose medical treatments that do not require surgical intervention. OBJECTIVE: Many drugs are used to treat the symptoms associated with uterine fibroids. The main objective of this systematic review is to give an up-to-date account of potential pharmacological agents (non-surgical methods) for the management of uterine leiomyomas. SEARCH STRATEGY: PubMed was searched for scientific and clinical literature using the keyword 'uterine fibroids' along with the drug names described in each section. For example, 'uterine fibroids' and 'ulipristal acetate' were the keywords used to search for literature on ulipristal acetate (UPA). RESULTS: Various preclinical and clinical studies have shown that some drugs and herbal formulations exhibit activity in the management of uterine leiomyomas. Recent studies found that drugs such as UPA, elagolix, EC313, asoprisnol, nutritional supplements and herbal preparations were helpful in treating the symptoms associated with uterine leiomyomas. CONCLUSION: Many drugs show efficacy in patients with symptomatic uterine fibroids. UPA is one of the most studied and prescribed medicines for uterine fibroids; however, its usage has been restricted due to a few recent incidences of hepatic toxicity. Herbal drugs and natural supplements have also shown promising effects on uterine fibroids. The synergistic effects of nutritional and herbal supplements have been reported in certain cases, and should be studied in detail. Further research is warranted to identify the mode of action of the drugs, and to determine the precise conditions that would explain the causes of toxicity in some patients.

Diagnosis and management of uterine fibroids: current trends and future strategies.

Uterine fibroids (UFs), leiomyomas or myomas, are a type of malignancy that affects the smooth muscle of the uterus, and it is most commonly detected in women of reproductive age. Uterine fibroids are benign monoclonal growths that emerge from uterine smooth muscle cells (myometrium) as well as fibroblasts. Uterine fibroid symptoms include abnormal menstrual bleeding leading to anaemia, tiredness, chronic vaginal discharge, and pain during periods. Other symptoms include protrusion of the abdomen, pain during intercourse, dysfunctions of bladder/bowel leading to urinary incontinence/retention, pain, and constipation. It is also associated with reproductive issues like impaired fertility, conceiving complications, and adverse obstetric outcomes. It is the leading cause of gynaecological hospitalisation in the American subcontinent and a common reason for the hysterectomy. Twenty-five percent of the reproductive women experience the symptoms of uterine fibroids, and among them, around 25% require hospitalization due to the severity of the disease. The frequency of the disease remains underestimated as many women stay asymptomatic and symptoms appear gradually; therefore, the condition remains undiagnosed. The exact frequency of uterine fibroids varies depending on the diagnosis, and the population investigated; nonetheless, the incidence of uterine fibroids in reproductive women ranges from 5.4 percent to 77 percent. The uterine fibroid treatment included painkillers, supplementation with iron, vitamin D3, birth control, hormone therapy, gonadotropin-releasing hormone (GnRH) agonists, drugs modulating the estrogen receptors, and surgical removal of the fibroids. However, more research needed at the level of gene to get a keen insight and treat the disease efficiently.

Curcumol, a major terpenoid from Curcumae Rhizoma, attenuates human uterine leiomyoma cell development via the p38MAPK/NF-κB pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Uterine fibroids (UFs) are the most common benign tumors in women of reproductive age. Curcumae Rhizoma, the main essential oil component of which is curcumol, is widely used for the treatment of phymatosis in China due to its antitumor, anti-inflammatory, antithrombin, anti-tissue fibrosis and anti-oxygen pharmacological activities, but its potential for the treatment of UFs has not been evaluated. AIM OF THE STUDY: This study aimed to investigate the effects and mechanisms of curcumol intervention in human uterine leiomyoma cells (UMCs). MATERIALS AND METHODS: Putative targets of curcumol intervention in UFs were identified using network pharmacology strategies. Molecular docking was performed to assess the binding affinity of curcumol to core targets. A concentration gradient of curcumol (0, 50, 100, 200, 300, 400 and 500 µM) or RU-486 (mifepristone, 0, 10, 20, 40, 50, and 100 µM) was applied to UMCs, and cell viability was detected by the CCK-8 assay. Cell apoptosis and cell cycle were examined by flow cytometry, and cell migration was assessed by a wound-healing assay. Additionally, the mRNA and protein expression levels of critical pathway components were evaluated by RT‒PCR and western blotting. Finally, the actions of curcumol on different tumor cell lines were summarized. RESULTS: Network pharmacology predicted 62 genes with roles in the treatment of UFs with curcumol, and MAPK14 (p38MAPK) displayed a higher interaction degree. GO enrichment and KEGG analyses revealed that the core genes were abundantly enriched in the MAPK signaling pathway. The molecular binding of curcumol to core targets was relatively stable. In UMCs, 200, 300 and 400 µM curcumol treatment for 24 h decreased cell viability compared with that in the control group, and the greatest effect was detected at 48 h and maintained until 72 h. Curcumol arrested cells in the G0/G1 phase and subsequently suppressed mitosis, promoted early apoptosis and reduced the degree of wound healing in a concentration-dependent manner in UMCs. Furthermore, 200 µM curcumol decreased the mRNA and protein expression of p38MAPK, the mRNA expression of NF-κB, and the protein expression of Ki-67 and increased the mRNA and protein expression of Caspase 9. Curcumol (300 and 400 µM) decreased the mRNA and protein expression of p38MAPK, NF-κB, and Ki-67 and increased the protein expression of Caspase 9 in UMCs. Curcumol was demonstrated to treat tumor cell lines, including breast cancer, ovarian cancer, lung cancer, gastric cancer, liver cancer and nasopharyngeal carcinoma, but its effects on benign tumors have not yet been reported. CONCLUSION: Curcumol suppresses cell proliferation and cell migration while arresting the cell cycle in the G0/G1 phase and inducing cell apoptosis in UMCs via a mechanism related to p38MAPK/NF-κB pathway regulation. Curcumol may be a potential therapeutic and preventive agent in the treatment of benign tumors such as UFs.

The efficacy and safety of Chinese herbal medicine Guizhi Fuling capsule combined with low dose mifepristone in the treatment of uterine fibroids: a systematic review and meta-analysis of 28 randomized controlled trials.

OBJECTIVE: Guizhi Fuling Capsule (GZFL), a classic traditional Chinese medicine prescription, is often recommended for the treatment of uterine fibroids (UFs). However, the efficacy and safety of GZFL in combination with low-dose mifepristone (MFP) remains controversial. MATERIALS AND METHODS: We searched eight literature databases and two clinical trial registries for randomized controlled trials (RCTs) of the efficacy and safety of GZFL combined with low-dose MFP in the treatment of UFs from database inception to April 24, 2022. Data analysis was performed using the Meta package in RStudio and RevMan 5.4. GRADE pro3.6.1 software was used for the assessment of evidence quality. RESULTS: Twenty-eight RCTs were included in this study, including a total of 2813 patients. The meta-analysis showed that compared with low-dose MFP alone, GZFL combined with low-dose MFP significantly reduced follicle stimulating hormone (p < 0.001), estradiol (p < 0.001), progesterone (p < 0.001), luteinizing hormone (p < 0.001), uterine fibroids volume (p < 0.001), uterine volume (p < 0.001), menstrual flow (p < 0.001) and increased clinical efficiency rate (p < 0.001). Meanwhile, GZFL combined with low-dose MFP did not significantly increase the incidence of adverse drug reactions compared with low-dose MFP alone (p = 0.16). The quality of the evidence for the outcomes ranged from "very low" to "moderate." CONCLUSION: This study suggests that GZFL combined with low-dose MFP is more effective and safe in the treatment of UFs, and it is a potential treatment for UFs. However, due to the poor quality of the included RCTs formulations, we recommend a rigorous, high-quality, large-sample trial to confirm our findings.

Immunohistochemical Expression of Vitamin D Receptor in Uterine Fibroids.

One of the many factors involved in the development of uterine fibroids is vitamin D deficiency. One aspect of this deficiency is decreased serum concentration of calcidiol-25(OH)D, a metabolite of D3 vitamin. The active form of vitamin D3, which arises after numerous enzymatic reactions, is calcitriol-1,25(OH)2D3; this compound is transported to various body tissues. Vitamin D possesses extra-genomic effects due to its influence on various signaling pathways, i.e., through activating tyrosine kinases and by genomic effects via binding to a specific nuclear receptor, vitamin D receptor (VDR). The vitamin D/VDR complex regulates the expression of genes and is involved in the pathogenesis of fibroids. Numerous studies have shown that vitamin D supplementation reduces fibroid size. It has also been shown that the expression of VDR in myoma tissue is significantly lower than in the uterine muscle tissue at the tumor periphery. However, the expression of VDR in non-myoma uterine muscle has not previously been investigated. Our VDR expression studies were performed immunohistochemically with tissue microarrays (TMA) in three tissue groups: 98 uterine myoma tissues, 98 uterine tissues (tumor margin), and 12 tissues of normal uterine muscle (i.e., without fibroids). A statistical analysis showed significantly lower VDR expression in uterine muscle at the periphery of the fibroid than in healthy uterine muscle. Lower expression of VDR at the periphery of the myoma compared to that in normal uterine muscle may indicate potential for new myomas. This observation and the described reduction in the size of fibroids after vitamin D supplementation supports the hypothesis of causal development of uterine fibroids and may be useful for the prevention of re-development in the event of their excision from the uterus.

A measure for perioperative anxiety symptoms in patients with FUAS - treated uterine fibroids: development and validation.

OBJECTIVE: To develop a scale that measured the perioperative anxiety symptoms of uterine fibroids (PASM-UF) treated with focused ultrasound ablation surgery (FUAS). METHODS: A panel of gynecologists, nurses, and patient-reported outcome (PRO) experts created a draft of the PASM-UF scale. Women who underwent FUAS for uterine fibroids were recruited for its psychometric validation. Assessments were conducted during admission, before surgery, and at discharge. The Symptom Checklist-90 (SCL-90) was administered to assess criterion validity. We assessed the relationship between the developed PASM-UF and the SCL-90 via a correlation analysis. Cronbach's alpha was used to assess internal consistency for reliability. RESULTS: We included five items, pain, lack of appetite, fatigue (tiredness), disturbed sleep, and anxiety, in the final version of the PASM-UF. Data were collected from 228 patients. Cronbach's alpha was 0.745, whereas the correlation coefficient between SCL-90 and PASM-UF was 0.345 (p < 0.001). The total PASM-UF scores were significantly higher in patients whose SCL-90 scores were ≥160 compared to those with <160 (9.85 ± 9.07 vs. 4.01 ± 5.15, p = .002). Those who did not complete the SCL-90 reported lower PASM-UF scores than those who did (2.33 ± 3.27 vs. 4.67 ± 5.99, p = .006). Patients reported significantly lower PASM-UF scores postoperatively than preoperatively (2.95 ± 4.18 vs. 3.92 ± 4.90, p = .002). CONCLUSIONS: The PASM-UF is a valid, reliable, and sensitive scale for assessing perioperative anxiety levels among women with uterine fibroids. Statistical analysis suggests that it is also an effective instrument for scientific research.Key MessageWe developed a brief scale to assess anxiety in perioperative patients with uterine fibroids. In addition, the scale monitored the anxiety levels at multiple frequencies and did not increase burden on the patients. The scale has been proven to be effective, reliable, and highly sensitive.

Guizhi Fuling Capsule inhibits uterine fibroids growth by modulating Med12-mediated Wnt/ß-Catenin signaling pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Guizhi Fuling Capsule (GFC) is a famous traditional Chinese medicine (TCM) formula recorded in Synopsis of the Golden Chamber, which has achieved obvious effects in the treatment of uterine fibroids (UFs). AIM OF STUDY: Mediator complex subunit 12 (Med12) mutations were closely related to UFs in 85% of fibroid cases. The Wnt/ß-Catenin signaling pathway plays an important role in the occurrence and development of UFs. This study aims to explore the pharmacological mechanism of GFC against UFs in which the Med12-mediated Wnt/ß-Catenin pathway is involved. MATERIALS AND METHODS: Med12 was silenced in uterine fibroid cells (UFCs) using a lentivirus-based Med12 gene-specific RNA interference (RNAi) strategy. Cell proliferation was performed by CCK-8 assay, cell apoptosis and cell cycle were measured by flow cytometry. The rat model of UFs was established by injecting estradiol benzoate and progesterone. Forty-eight rats were divided into six groups, the low-dose GFC (L-GFC) group, the medium-dose GFC (M-GFC) group and the high-dose GFC (H-GFC) group were intragastrically treated with GFC solution at 0.25 g/kg, 0.50 g/kg and 1.00 g/kg per day for 8 weeks, the positive control (PC) group was administrated with mifepristone (2.70 mg/kg/day), the normal control (NC) group and the model control (MC) group were given equal volume of normal saline once a day for 8 weeks. The histopathological changes of uterine tissues were evaluated by H&E staining. The expression of Med12 in uterine tissues were detected by immunohistochemistry. The protein and mRNA levels of associated genes were evaluated by western bolt and real time-PCR, respectively. Related indicators involved in Wnt/ß-Catenin pathway, such as Wnt1, ß-Catenin, Cyclin D1, TCF1/TCF7 and C-myc, were compared among different groups. RESULTS: The Wnt/ß-Catenin signaling pathway was inhibited after Med12 gene was knocked out in UFCs. GFC-containing serum could induce cell apoptosis, make the cell cycle stagnated in G0/G1 phase to inhibiting the proliferation and reduce the expression of Wnt1, ß-Catenin, Cyclin D1, TCF1/TCF7, and C-myc in control-shRNA cells, while had no significant effect on Med12-shRNA cells. Compared with the MC group, the weight, endometrial thickness, and pathological structure of the uterus in the GFC treated groups were significantly improved. The expression of Med12, Wnt1, ß-Catenin, Cyclin D1, TCF1/TCF7, and C-myc that related to Wnt/ß-Catenin pathway in the GFC treated groups were decreased with the increase of dosage administration. CONCLUSIONS: GFC inhibited UFs growth, which was directly associated with Med12 modulated Wnt/ß-Catenin signaling pathway. This study provided new perspective to understand the therapeutic mechanism of UFs.

Dietary Natural Compounds and Vitamins as Potential Cofactors in Uterine Fibroids Growth and Development.

An analysis of the literature generated within the past 20 year-span concerning risks of uterine fibroids (UFs) occurrence and dietary factors was carried out. A link between Vitamin D deficiency and UFs formation is strongly indicated, making it a potent compound in leiomyoma therapy. Analogs of the 25-hydroxyvitamin D3, not susceptible to degradation by tissue 24-hydroxylase, appear to be especially promising and tend to show better therapeutic results. Although research on the role of Vitamin A in the formation of fibroids is contradictory, Vitamin A-enriched diet, as well as synthetic retinoid analogues, may be preventative or limit the growth of fibroids. Unambiguous conclusions cannot be drawn regarding Vitamin E and C supplementation, except for alpha-tocopherol. Alpha-tocopherol as a phytoestrogen taking part in the modulation of estrogen receptors (ERs) involved in UF etiology, should be particularly avoided in therapy. A diet enriched in fruits and vegetables, as sources of carotenoids, polyphenols, quercetin, and indole-3-carbinol, constitutes an easily modifiable lifestyle element with beneficial results in patients with UFs. Other natural substances, such as curcumin, can reduce the oxidative stress and protect against inflammation in leiomyoma. Although the exact effect of probiotics on uterine fibroids has not yet been thoroughly evaluated at this point, the protective role of dairy products, i.e., yogurt consumption, has been indicated. Trace elements such as selenium can also contribute to antioxidative and anti-inflammatory properties of a recommended diet. In contrast, heavy metals, endocrine disrupting chemicals, cigarette smoking, and a diet low in antioxidants and fiber were, alongside genetic predispositions, associated with UFs formation.

Nutraceuticals in fibroid management after ulipristal acetate administration: An observational study on patients' compliance.

OBJECTIVE: On May 13, 2020, the Italian government Pharmaceutical Agency (AIFA) stopped ulipristal acetate (UPA) treatments for uterine fibroids (UFs), so patients shifted to other natural treatments. The authors tested the patients' compliance with UF natural treatments. METHODS: Thirty patients of reproductive age (30-45 years) affected by UFs stopped UPA intake and started epigallocatechin gallate (EGCG) plus vitamin D3 treatment. Patients were asked to complete the Uterine Fibroid symptoms and Quality of Life (UFS-QOL) questionnaire, divided into symptoms severity (SS) and health-related quality of life (HRQL), after UPA suspension and to repeat it after 3 months of natural treatment. Collected data were analyzed using paired Student's t test, considering a P value less than 0.05 to be significant. RESULTS: The SS score was significantly lower (-12.19%) for natural treatment when compared with UPA administration. The HRQL score significantly improved (+11.79%) after shifting treatment from UPA to natural therapy. All the investigated parameters appeared improved by 10% after the natural treatment. No adverse effects were reported following the natural treatment. CONCLUSION: Natural treatments showed positive compliance in patients with UFs, based on HRQL score, representing an alternative therapeutic opportunity for patients forced to stop UPA therapy.

Uterine Fibroids in Black Women: A Race-Stratified Subgroup Analysis of Treatment Outcomes After Laparoscopic Radiofrequency Ablation.

Background: The disease and treatment burden of uterine fibroids (UF) in Black women is substantially greater compared with other racial groups, with higher rates of complications and poorer outcomes with both hysterectomy and myomectomy. The inequities in the access Black women have to minimally invasive routes of surgery contribute to their burden of illness. Laparoscopic radiofrequency ablation (LAP-RFA) is a minimally invasive, safe, and effective uterine-sparing treatment option. Methods: This subgroup analysis of the LAP-RFA Pivotal Trial stratified outcomes by race comparing White women (n = 28, 21%) versus Black women (n = 46, 34%). Results: At baseline, Black women had more fibroids on average (7.3 vs. 3.7; P ≤ 0.001), a greater symptom severity score (SSS) (P ≤ 0.001), and a lower health-related quality of life (HRQoL) score (P = 0.005) than White women. At 36 months post-treatment with LAP-RFA, the statistical differences that existed with baseline SSS and HRQoL score were eliminated between Black and White women. Menstrual blood loss (140.1 mL vs. 127.02 mL; P = 0.44) and mean fibroid volume reduction (47.5 cm3 vs. 36.0 cm3; P = 0.17) were similar between Black and White women at 12 months. Although not statistically significant, the intraoperative total blood loss and uterine blood loss was lower in Black women than White women, despite greater operative time (160 minutes vs. 137 minutes; P = 0.09). Conclusions: These results are promising in providing an alternative uterine-sparing option for Black women and may help to provide a minimally invasive option that can address some of the racial inequities in care for Black women with UF.

Efficacy of Chinese herbal prescriptions containing Ejiao or Velvet antler for management of uterine fibroids: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: To evaluate the efficacy and safety of the controversial Chinese herbal prescriptions containing Ejiao or Velvet antler (VA) in the treatment of uterine fibroids. METHODS: We searched 4 famous Chinese databases, the Chinese Clinical Trial Registry, PubMed, Cochrane Central, Google Scholar, Embase, and J-STAGE up to July 2019. We included all eligible randomized controlled trials (RCTs) which compared Chinese herbal prescriptions containing Ejiao or VA (E/VA) with placebo, pharmaceutical intervention, surgery, or other traditional Chinese medicines (TCMs) for uterine fibroids and assessed the risk of bias according to the Cochrane Collaboration's tool. The software Review Manager (RevMan) 5.1 was used for data analysis. RESULTS: A total of 9 RCTs involving 844 patients were identified. Meta-analyses demonstrated that TCM (E/VA) plus mifepristone reduced the volume of uterine fibroids to a greater degree than mifepristone alone [standardized mean difference (SMD): 0.59, 95% CI: 0.33 to 0.85, P<0.00001, I2=50%]; TCM (E/VA) did not enlarge the volume of fibroids when menopausal hormone therapy (MHT) significantly increased the volume (SMD: 1.06, 95% CI: 0.73 to 1.38, P<0.00001, I2=0. The uterine volume change difference was larger via combination therapy of TCM (E/VA) and mifepristone than that of mifepristone (SMD: 0.29, 95% CI: 0.09 to 0.49, P=0.005, I2=0%). The TCM (E/VA) group of had an advantage over the control group in the improvement of fibroid-related symptoms [relative risk (RR): 1.24, 95% CI: 1.15 to 1.35, P<0.00001, I2=0%]. It was found that TCM (E/VA) plus mifepristone could lower estradiol (E2) levels to a greater degree than mifepristone alone (SMD: 1.63, 95% CI: 0.42 to 2.83, P=0.008, I2=97%), as well as progesterone (P) level (SMD: 0.79, 95% CI: 0.55 to 1.04, P<0.00001, I2=43%) in non-menopausal women. A total of 5 studies reported adverse events (AEs), the TCM (E/VA) group was potentially safer than the control group, with lower incidence of AEs (RR: 0.24, 95% CI: 0.15 to 0.40, P<0.00001, I2=25.8%). DISCUSSION: TCM prescriptions containing E/VA seemed superior to the control group in shrinking the volume of uterine fibroids and uterus, improving related symptoms, and reducing non-menopausal women's E2 and P levels, with lower incidence of AEs.

Extracellular matrix and Hippo signaling as therapeutic targets of antifibrotic compounds for uterine fibroids.

BACKGROUND: Uterine fibroids are highly prevalent, collagen-rich, mechanically stiff, fibrotic tumors for which new therapeutic options are needed. Increased extracellular matrix (ECM) stiffness activates mechanical signaling and Hippo/YAP promoting fibroid growth, but no prior studies have tested either as a therapeutic target. We tested the hypothesis that injection of a purified form of collagenase Clostridium histolyticum (CCH) that selectively digests type I and type III collagens would alter ECM stiffness, Hippo signaling, and selectively reduce fibroid cell growth. We also used two FDA-approved drugs, verteporfin and nintedanib, to elucidate the role of Hippo/YAP signaling in uterine fibroid and myometrial cells. METHODS: The clinical trial was registered (NCT02889848). Stiffness of samples was measured by rheometry. Protein expression in surgical samples was analyzed via immunofluorescence. Protein and gene expression in uterine fibroid or myometrial cell lines were measured by real time PCR and western blot, and immunofluorescence. RESULTS: Injection of CCH at high doses (0.1-0.2 mg/cm3 ) into fibroids resulted in a 46% reduction in stiffness in injected fibroids compared to controls after 60 days. Levels of the cell proliferation marker proliferative cell nuclear antigen (PCNA) were decreased in fibroids 60 days after injection at high doses of CCH. Key Hippo signaling factors, specifically the transcriptionally inactive phosphorylated YAP (p-YAP), was increased at high CCH doses, supporting the role of YAP in fibroid growth. Furthermore, inhibition of YAP via verteporfin (YAP inhibitor) decreased cell proliferation, gene and protein expression of key factors promoting fibrosis and mechanotransduction in fibroid cells. Additionally, the anti-fibrotic drug, nintedanib, inhibited YAP and showed anti-fibrotic effects. CONCLUSIONS: This is the first report that in vivo injection of collagenase into uterine fibroids led to a reduction in Hippo/YAP signaling and crucial genes and pathways involved in fibroid growth. These results indicate that targeting ECM stiffness and Hippo signaling might be an effective strategy for uterine fibroids.

Comparison between radiofrequency ablation combined with mifepristone and radiofrequency ablation for large uterine fibroids.

OBJECTIVE: To evaluate the clinical outcomes of transvaginal ultrasound-guided (US-guided) radiofrequency ablation (RFA) combined with mifepristone for the treatment of large uterine fibroids. METHODS: Between June 2016 and December 2018, a total of 30 patients with symptomatic uterine fibroids (≥5cm) who underwent transvaginal US-guided RFA combined with mifepristone were included in this retrospective study. A matching cohort of 30 patients underwent transvaginal US-guided RFA without mifepristone as controls. The technical efficacy, complications and mid-term treatment effectiveness were assessed and compared with the controls. RESULTS: The mean volume of uterine fibroid was 168.3 ± 40.1 cm3. The mean ablation time was 23.5 ± 11.3 min in the combined treatment group, which was demonstrably less than that of the RFA group, which was 45.7 ± 6.8 min. The mean number of punctures was 2.2 ± 0.6 in the combined treatment group, which was significantly less than that of the RFA group. No major complications occurred. The mean percentages of regression of fibroid at 3 and 12 months after the course of the combined treatment were 73.3% and 90.1%, respectively, which were significantly more than those of the RFA group. Quality of life and symptom scores improved in both groups but to a greater extent in the combined treatment group. CONCLUSIONS: US-guided RFA combined with mifepristone might be a simple, safe and effective alternative for the treatment of large uterine fibroids.

Nutrition in Gynecological Diseases: Current Perspectives.

Diet and nutrition are fundamental in maintaining the general health of populations, including women's health. Health status can be affected by nutrient deficiency and vice versa. Gene-nutrient interactions are important contributors to health management and disease prevention. Nutrition can alter gene expression, as well as the susceptibility to diseases, including cancer, through several mechanisms. Gynecological diseases in general are diseases involving the female reproductive system and include benign and malignant tumors, infections, and endocrine diseases. Benign diseases such as uterine fibroids and endometriosis are common, with a negative impact on women's quality of life, while malignant tumors are among the most common cause of death in the recent years. In this comprehensive review article, a bibliographic search was performed for retrieving information about nutrients and how their deficiencies can be associated with gynecological diseases, namely polycystic ovary syndrome, infertility, uterine fibroids, endometriosis, dysmenorrhea, and infections, as well as cervical, endometrial, and ovarian cancers. Moreover, we discussed the potential beneficial impact of promising natural compounds and dietary supplements on alleviating these significant diseases.
