RESUMO

PURPOSE: Since late 2017, the use of ulipristal acetate 5 mg (UPA; Proprietary name: Esmya) has been under review in the European Union, due to an emerging hepatic risk. In February 2018 and in July 2018, the Spanish Agency of Medicines and Medical Devices and the marketing authorization holder put two risk minimization measures (RMM) in place, in order to inform about new safety information and to mitigate this risk. This study aims to assess RMM effectiveness in Spain, by performing an interrupted time-series (ITS) analyses, between 2014 and 2019. METHOD: Two quasi-experimental ITS analyses to examine the use of UPA before and after the RMM release were performed: (a) an ecological study using aggregated data from a drug consumption database; and (b) a study using primary healthcare data gathered from electronic clinical records. RESULTS: Regulatory interventions were associated with an immediate and significant decrease level of DID (the number of DDD dispensed per 100 000 inhabitants and day) and incidence. The DID was 70% less than expected 12 months after the interventions. This value was 59% for the incidence. However, a change in the slope was not observed and the use started rising again in the last segment of the study period. CONCLUSION: Despite RMM had an immediate strong impact on UPA use, the last segment upward trend in the long-term might have been affected by the lack of comparable therapeutic alternatives. Further studies should be performed to confirm the increase trend observed and analyze subsequent measures and additional data.

RESUMO

Uterine fibroids, benign tumors originating from uterine smooth muscle cells, vary in prevalence depending on patient ethnicity, hormonal exposure, and genetics. Due to their high incidence, these neoplasms pose a significant burden on healthcare systems. Current treatment strategies range from routine monitoring in asymptomatic cases to surgical procedures such as myomectomy or hysterectomy in symptomatic patients, with an increasing trend toward uterus-preserving or non-surgical alternatives. This review examines the existing medical treatments for uterine fibroids and delves into the potential of emerging therapies. A scoping review of the literature was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. Medical therapies are divided into hormonal and non-hormonal treatments; however, long-term, safe, and effective treatments in the treatment of uterine fibroids are limited. In addition to established therapies, there is an increasing number of studies investigating the effect of substances such as vitamin D or green tea extract on uterine fibroids. Some studies investigate acupuncture as a possible alternative therapy. While existing treatments offer symptomatic relief and preparation for surgery, our findings point to a significant need for further research into long-term solutions, especially owing to recent limitations in the use of ulipristal acetate due to risk of liver damage. Initial studies involving vitamin D and epigallocatechin gallate are encouraging; however, additional research is required to establish definitive therapeutic roles.

RESUMO

BACKGROUND: Emergency contraception reduces the risk of unintended pregnancy, after unprotected sexual intercourse or contraceptive failure. In Belgium, emergency contraception is available without a prescription and pharmacists play therefore a crucial role in dispensing emergency contraception. AIM: This study assesses the dispensing practices of emergency contraception by pharmacists in two regions of Belgium. METHOD AND DESIGN: Simulated patient study, using a predefined scenario, evaluating a request for emergency contraception. The scenario involves a 25-year-old woman not using contraception, who had unprotected sexual intercourse 84 h (3.5 days) ago. Her last menstrual period was 10 days ago. POPULATION: 260 pharmacies were randomly selected. Principal outcome: proportion of pharmacists who deliver the adequate emergency contraception. We considered the following responses as adequate: Prescribing ulipristal acetate or redirecting to another pharmacy, in case of unavailability, or referring for a copper IUD. RESULTS: We analysed the data obtained in 216 pharmacies (216/260 = 83.1%). In 64% of cases, adequate dispensing of emergency contraception (dispensing of ulipristal acetate or referral for intrauterine device insertion) occurred. There was an association between correct dispensing and asking appropriate questions, such as the date of the last menstrual period and the date of the risky sexual intercourse. CONCLUSION: More than one-third of visited pharmacies did not distribute appropriate emergency contraception, underlining the need for improvement. We hypothesise that this may be achieved with appropriate training, use a dispensing checklist.

RESUMO

Selective progesterone receptor modulators (SPRMs) are synthetic steroid compounds that interact with the progesterone receptor, inducing various agonist, antagonist or mixed responses. First identified with mifepristone, they are now represented by ulipristal acetate (UPA), used for emergency contraception and uterine fibroids. Despite a few rare cases of severe hepatic insufficiency, SPRMs offer advantages in the treatment of uterine fibroids, reducing their volume without the hypoestrogenic side-effects of GnRH agonists, thus preserving patients' bone capital and quality of life. Despite temporary suspension of UPA administrated on a daily basis, research is exploring the potential of SPRMs in the management of endometriosis, adenomyosis and breast cancer. Despite certain concerns, SPRMs offer promising prospects in gynecological pathologies, opening up new therapeutic avenues to improve women's health and quality of life. This article describes the case of a patient with peritoneal leiomyomatosis for whom UPA significantly alleviated symptoms, reduced disease progression and improved quality of life, even allowing a pregnancy.


Les modulateurs sélectifs des récepteurs de la progestérone (SPRMs) sont des composés stéroïdiens synthétiques qui interagissent via le récepteur de la progestérone, induisant diverses réponses, agonistes, antagonistes ou mixtes. Les SPRMs ont d'abord été représentés par la mifépristone, utilisée pour ses propriétés antagonistes dans la gestion de l'interruption de la grossesse, puis par l'acétate d'ulipristal, qui est indiqué en contraception d'urgence, mais aussi pour la gestion de myomes utérins symptomatiques. Les SPRMs permettent de réduire le volume des myomes utérins, sans induire les effets secondaires d'hypo-œstrogénie des agonistes de la GnRH, préservant ainsi le capital osseux et la qualité de vie des patientes. Néanmoins, quelques cas graves d'insuffisance hépatique ont conduit à la suspension temporaire de l'acétate d'ulipristal en traitement chronique. En dépit de certaines réserves, les SPRMs offrent des perspectives dans les affections gynécologiques, ouvrant de nouvelles voies thérapeutiques pour améliorer la santé et la qualité de vie des femmes. Des recherches explorent leur potentiel dans l'endométriose, l'adénomyose et la chimioprévention du cancer du sein. Nous décrivons ici le cas d'une patiente avec léiomyomatose péritonéale pour laquelle l'acétate d'ulipristal a significativement réduit les symptômes et l'évolution de la maladie, tout en améliorant la qualité de vie de la patiente, avec même l'obtention d'une grossesse menée à terme.

RESUMO

OBJECTIVE: To investigate safety and effectiveness of NOMAC-E2 and levonorgestrel-containing COCs (COCLNG) in users over 40. METHODS: In this large, observational study, new users1 of NOMAC-E2 and COCLNG were recruited in Europe, Australia, and Latin America and followed-up via questionnaires. Incidence of venous thromboembolism (VTE) was expressed as incidence rate (IR; events/104 women-years [WY]). Unintended pregnancy was expressed by the Pearl Index (PI; contraceptive failures/100 WY). Mood and weight changes were defined as mean changes in mood score and percentage of body weight. RESULTS: Overall, 7,762 NOMAC-E2 and 6,059 COCLNG users over 40 were followed-up. NOMAC-E2 showed no increased VTE risk compared to COCLNG; confirmed events: 5 NOMAC-E2 (IR 5.9; 95% CI, 1.9-13.7) vs 4 COCLNG (IR 5.9; 95% CI, 1.6-15.1). Unintended pregnancy did not differ substantially between cohorts; confirmed events: 4 NOMAC-E2 (PI 0.05; 95% CI, 0.01-0.13) vs 5 COCLNG (PI 0.08; 95% CI, 0.03-0.18). No differential effect on mood and weight was observed between cohorts. CONCLUSIONS: NOMAC-E2 can be considered a valid alternative to COCLNG in perimenopausal women.

RESUMO

PURPOSE: The proliferation of breast epithelial cells increases during the luteal phase of the menstrual cycle, when they are exposed to progesterone, suggesting that ulipristal acetate, a selective progestin-receptor modulator (SPRM), may reduce breast cell proliferation with potential use in breast cancer chemoprevention. METHODS: Women aged 18-39 were randomized 1:1 to ulipristal 10-mg daily or to a combination oral contraceptive (COC) for 84 days. Participants underwent a breast biopsy and breast MRI at baseline and at end of study treatment. Proliferation of breast TDLU cells was evaluated by Ki67 immunohistochemical stain. We evaluated the breast MRIs for background parenchymal enhancement (BPE). All slides and images were masked for outcome evaluation. RESULTS: Twenty-eight treatment-compliant participants completed the study; 25 of whom had evaluable Ki67 results at baseline and on-treatment. From baseline to end of treatment, Ki67 % positivity (Ki67%+) decreased a median of 84% in the ulipristal group (N = 13; 2-sided p (2p) = 0.040) versus a median increase of 8% in the COC group (N = 12; 2p = 0.85). Median BPE scores decreased from 3 to 1 in the ulipristal group (p = 0.008) and did not decrease in the COC group. CONCLUSION: Ulipristal was associated with a major decrease in Ki67%+ and BPE. Ulipristal would warrant further investigation for breast cancer chemoprevention were it not for concerns about its liver toxicity. Novel SPRMs without liver toxicity could provide a new approach to breast cancer chemoprevention. TRIAL REGISTRATION: NCT02922127, 4 October 2016.

RESUMO

Ulipristal acetate (UPA) is a medical treatment for uterine fibroids and was authorized for surgical pre-treatment in 2012 after the conduct of the PEARL I and II randomized controlled trials and for intermittent treatment after the observational PEARL III and IV trials. However, UPA came into disrepute due to its temporary suspension in 2017 and 2020 because of an apparent association with liver injury. This clinical opinion paper aims to review the process of marketing authorization and implementation of UPA, in order to provide all involved stakeholders with recommendations for the introduction of future drugs. Before marketing authorization, the European Medicines Agency (EMA) states that Phase III registration trials should evaluate relevant outcomes in a representative population, while comparing to gold-standard treatment. This review shows that the representativeness of the study populations in all PEARL trials was limited, surgical outcomes were not evaluated and intermittent treatment was assessed without comparative groups. Implementation into clinical practice was extensive, with 900 000 prescribed treatment cycles in 5 years in Europe and Canada combined. Extremely high costs are involved in developing and evaluating pre-marketing studies in new drugs, influencing trial design and relevance of chosen outcomes, thereby impeding clinical applicability. It is vitally important that the marketing implementation after authorization is regulated in such way that necessary evidence is generated before widespread prescription of a new drug. All stakeholders, from pharmaceutical companies to authorizing bodies, governmental funding bodies and medical professionals should be aware of their role and take responsibility for their part in this process.

RESUMO

BACKGROUND: To evaluate the effects of a combined oral contraceptive containing 1.5 mg 17b-estradiol (E2) and 2.5 mg nomegestrol acetate (NOMAC) or 2 mg/daily dienogest (DNG) oral progestin on endometriosis-associated chronic pelvic pain (CPP) and on the quality of life (QoL) and sexual function, by a randomized study design. METHODS: The E2/NOMAC group and DNG group included 99 and 98 women, respectively. The levels of CPP were measured by the visual analogic scale (VAS). The QoL scores were investigated by the Short Form-36 questionnaire (SF-36). Finally, sexual function was studied using the Female Sexual Function Index (FSFI), while sexual distress was studied by the Female Sexual Distress Scale (FSDS). The study had 3, 6 and 12-month follow-ups. RESULTS: The intra-group analysis showed an improvement of the VAS score from baseline to the 12-month follow-up in the women of both groups (p < 0.001). The inter-group comparison showed a similar improvement of CPP (p = 0.06). Women on DNG had better SF-36 somatic (p < 0.01) and FSFI scores (p < 0.006) than women on E2/NOMAC at the 6- and 12-month follow-ups. CONCLUSIONS: The results support the efficacy of both hormonal treatments, even if DNG was more effective than E2/NOMAC in a limited intergroup comparison.

RESUMO

The aim of this study was to explore the mechanisms of action of alsevirone in prostate cancer (PC) in vitro and in vivo: CYP17A1 inhibition, cytotoxic, apoptotic, and antitumor effects in comparison with abiraterone. The CYP17A1-inhibitory activity was investigated in rat testicular microsomes using high-performance liquid chromatography. Testosterone levels were evaluated using enzyme-linked immunoassay. IC50 values were calculated for PC3, DU-145, LNCaP, and 22Rv1 cells using the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) test. The antitumor effect in vivo was studied in DU-145 and 22Rv1 subcutaneous xenografts in Balb/c nude mice. Alsevirone reduced the CYP17A1-inhibitory activity by 98% ± 0.2%. A statistically significant reduction in the testosterone concentration in murine blood was recorded after the 7th administration of 300 mg/kg alsevirone at 0.31 ± 0.03 ng/ml (p < .001) versus 0.98 ± 0.22 ng/ml (p = .392) after abiraterone administration and 1.52 ± 0.49 ng/ml in control animals. Alsevirone was more cytotoxic than abiraterone in DU-145, LNCaP, and 22Rv1 cells, with IC50 values of 23.80 ± 1.18 versus 151.43 ± 23.70 µM, 22.87 ± 0.54 versus 28.80 ± 1.61 µM, and 35.86 ± 5.63 versus 109.87 ± 35.15 µM, respectively. Alsevirone and abiraterone significantly increased annexin V-positive, caspase 3/7-positive, and activated Bcl-2-positive cells. In 22Rv1 xenografts, alsevirone 300 mg/kg × 10/24 h per os inhibited tumor growth: on Day 9 of treatment, tumor growth inhibition = 59% (p = .022). Thus, alsevirone demonstrated significant antitumor activity associated with CYP17A1 inhibition, apoptosis in PC cells, and testosterone reduction.

RESUMO

PURPOSE: To analyse the effect of ulipristal acetate (UPA) as emergency contraception (EC) on the gene expression of human endometrial cell line (HEC-1A) and endometrium from fertile women treated with UPA after ovulation. MATERIALS AND METHODS: HEC-1A cells were treated with UPA, and endometrial tissue from four healthy women was collected in cycles before, during and 2 months after post-ovulation pill intake. Ovulation and luteal phase were monitored, and endometrial biopsies were obtained at day LH + 7 in each cycle. In all cases, we analysed the expression profile of 192 genes associated to endometrial receptivity. RESULTS: We observed a significant change in total transcriptomic activity of UPA-treated HEC-1A cells compared to controls. In vivo, we also observed a trend to down-regulation of genes in the UPA-treated cycle that was partially restored in the post-treatment cycle. Altogether, our results supported a partially reversible effect of UPA in gene expression associated with uterine receptivity. CONCLUSIONS: When UPA was administered after ovulation, it seems to induce a down-regulation of the main genes involved in conditioning the endometrium for implantation. This effect is partially restored two months after pill intake. The action of UPA on the endometrium for users of EC should be further investigated.

RESUMO

Ulipristal acetate (UPA), used for the treatment in women with symptomatic fibroids, is associated with endometrial changes visualised on ultrasound as thickening up to more than 16 mm in approximately 10% of the patients. Is saline infusion sonography (SIS) a good alternative for more invasive techniques, to evaluate the presence of intrauterine pathology? Ten patients, presenting with UPA associated endometrial changes at their follow up ultra-sonographic evaluation, were included. Our study demonstrated that SIS is feasible and painless in patients presenting with UPA associated endometrial changes. The thickened endometrium appears to divide at the midline, making it possible to study both layers separately and exclude any suspected intrauterine pathology. Our findings suggest that SIS may be a first choice, non-invasive, painless technique to provide a proper visualisation to rule out intrauterine pathology when UPA associated endometrial changes are diagnosed after fibroid treatment. This is especially of clinical interest in front of assisted reproductive technology treatment. Invasive techniques can be withheld for patients in whom SIS examination is not contributive.Impact StatementWhat is already known on this subject? Reversible endometrial changes after ulipristal acetate (UPA) treatment in patients with symptomatic fibroids have been described. In patients who receive UPA, especially if planned to undergo ART, assessment of potential endometrial pathology is important as such interfere with proper implantation after ART. Consequently, clinicians may consider ruling out intrauterine pathology by invasive examinations such as biopsy or hysteroscopy after visualisation of the thickened endometrium.What do the results of this study add? Saline infusion sonography (SIS) was feasible and painless in patients presenting with UPA associated endometrial changes.What are the implications of these findings for clinical practice and/or further research? SIS may be a first choice, non-invasive, painless technique to provide a proper visualisation to rule out intrauterine pathology when UPA associated endometrial changes are diagnosed after fibroid treatment. This is especially of clinical interest in front of assisted reproductive technology treatment. Invasive techniques can be withheld for patients in whom SIS examination is not contributive in excluding intrauterine pathology.

RESUMO

OBJECTIVE: This study aimed to analyze the effects of a six-month therapy with ulipristal acetate (UPA) on myoma size and endometrial thickness in premenopausal women. MATERIAL AND METHODS: Seventy-four women undergoing conservative therapy with UPA were enrolled for this study. All women underwent transvaginal ultrasound evaluation to assess the endometrial thickness, and the number and size of myomas at the beginning and after six months. Hysteroscopy and biopsy were performed after six months, if necessary. RESULTS: After six months of treatment, sonographic examination showed a statistically significant (p < .05) reduction of the size of the largest myoma (56.3 ± 5.1 vs. 31.7 ± 10.1 mm) and a statistically significant (p < .05) increase in endometrial thickness (5.9 ± 2.1 vs. 9.7 ± 3.4 mm). Twenty-two patients with endometrial thickness >10 mm or nonhomogeneous pattern and ten patients with metrorrhagia underwent hysteroscopy: the most frequent finding was the combination of endometrial hypotrophy, floating surface, and chicken-wire vascular pattern aspect (14 cases, 43.7%). Histologic findings showed no case of complex hyperplasia. CONCLUSION: UPA is a safe, effective and assured method to decrease symptoms, reduce the need for surgery in premenopausal women suitable for the treatment.

RESUMO

Muscle wasting caused by catabolic reactions in skeletal muscle is commonly observed in patients with sepsis. Myostatin, a negative regulator of muscle mass, has been reported to be upregulated in diseases associated with muscle atrophy. However, the behavior of myostatin during sepsis is not well understood. Herein, we sought to investigate the expression and regulation of myostatin in skeletal muscle in mice inoculated with gram-negative bacteria. Interestingly, the protein level of myostatin was found to increase in the muscle of septic mice simultaneously with an increase in the levels of follistatin, NF-κΒ, myogenin, MyoD, p- FOXO3a, and p-Smad2. Furthermore, the inhibition of myostatin by YK11 repressed the levels of pro-inflammatory cytokines and organ damage markers in the bloodstream and in the major organs of mice, which originally increased in sepsis; thus, myostatin inhibition by YK11 decreased the mortality rate due to sepsis. The results of this study suggest that YK11 may help revert muscle wasting during sepsis and subdue the inflammatory environment, thereby highlighting its potential as a preventive agent for sepsis-related muscle wasting.

RESUMO

Ulipristal acetate is a drug used as emergency contraceptive (30 mg) and for the treatment of moderate to severe symptoms of uterine myomas (5 mg). After commercialization, and although the exact number is unknown, serious cases implying ulipristal acetate 5 mg as a contributing factor of liver injury, some leading to transplantation, were reported. These cases prompted to a restrict use of the drug in January 2021 by the European Medicines Agency. This work aimed to fully review pharmacokinetic aspects, namely focusing in the ulipristal acetate metabolism and other hypothetical toxicological underlying mechanisms that may predispose to drug-induced liver injury (DILI). The high lipophilicity, the extensive hepatic metabolism, the long half-life of the drug and of its major active metabolite, the long-term course of treatment, and possibility due to the formation of epoxide reactive may be contributing factors. Scientific results also points evidence to consider monitorization of liver function during ulipristal acetate treatment.

RESUMO

BACKGROUND: Sex steroids could explain the course of multiple sclerosis (MS) in pregnancy. OBJECTIVE: To compare the annualized relapse rate (ARR) 12 weeks post-partum in women treated with nomegestrol acetate (NOMAc) and 17-beta-estradiol (E2) versus placebo. METHODS: POPARTMUS is a randomized, proof-of-concept trial in women with MS, receiving oral NOMAc 10 mg/day and transdermal estradiol 75 µg/week, or placebo. RESULTS: Recruitment was stopped prematurely due to slow inclusions (n = 202). No treatment effect was observed on ARR after 12 weeks (sex steroids = 0.90 (0.58-1.39), placebo = 0.97 (0.63-1.50) (p = 0.79)). CONCLUSION: POPARTMUS failed showing efficacy of a NOMAc-E2 combination in preventing post-partum relapses.

RESUMO

RESEARCH QUESTION: What is the evolution of adenomyosis on magnetic resonance imaging (MRI) after a 3-month treatment course of daily 5 mg doses of ulipristal acetate (UPA) for symptomatic fibroids? DESIGN: A monocentric prospective pilot study on patients who underwent a 3-month treatment course of UPA for symptomatic fibroids between January 2014 and December 2017. Patients underwent pelvic MRI shortly before (pre-MRI) and after treatment (post-MRI). The diagnosis of adenomyosis on MRI was defined by the observation of intramyometrial cysts and/or haemorrhagic foci within these cystic cavities and/or a thickening of the junctional zone >12 mm. The progression of adenomyosis was defined by the presence of at least one of the aforementioned criteria of adenomyosis on the pre-MRI and by at least one of the following on the post-MRI: (i) increased thickness of the junctional zone ≥20% and/or (ii) increased number of intramyometrial cysts. The appearance of adenomyosis was defined by the absence of the aforementioned criteria of adenomyosis on the pre-MRI and the presence of at least one of these criteria on the post-MRI. RESULTS: Seventy-two patients were included. The MRI features of adenomyosis progressed for 12 of 15 patients (80.0%) for whom adenomyosis was identified on the pre-MRI. An appearance of adenomyosis was identified after treatment for 15 of 57 patients (26.3%) for whom adenomyosis was not identified on the pre-MRI. CONCLUSIONS: A 3-month treatment course of daily 5 mg doses of UPA could provoke a short-term progression or an emergence of typical adenomyosis intramyometrial cysts on MRI examinations.

RESUMO

AIMS: Uterine fibroids are benign tumours that cause various complaints. These complaints may significantly compromise quality of life, necessitating a clinical intervention in 25-50% of the affected women. Hysterectomy, myomectomy or embolization may offer symptomatic relief, but are costly, include a recovery period, can cause serious side-effects, sometimes fail to treat symptoms completely and are not always desired by patients. Ulipristal is a conservative long-term treatment that has a fibroid-volume decreasing effect, acceptable side-effects while preserving fertility and may be an alternative to surgical alternatives. Currently, ulipristal is investigated by the European Medicine Agency and suspended from marketing authorization because it may cause drug-induced liver injury (DILI). However, many drugs can cause severe DILI and prospective studies estimate 14-19 DILI cases/100 000 people. METHODS: This overview will discuss the risk-benefit balance between ulipristal and DILI, describe the safety-efficacy balance of ulipristal and its alternative treatments and the arguments that led to the suspension of its marketing authorization. RESULTS: Ulipristal may be associated with DILI resulting in a risk of severe liver injury in 1.5:100 000 patients and fatal liver injury in 0.1:100 000 patients. This risk needs to be weighed against the higher mortality risk of >1:1000 and higher incidence of severe complications after surgery. CONCLUSION: The DILI risk of ulipristal is considerably lower than that of other medicines that are not suspended, nor need additional safety measures. When evaluating drugs and drug safety, risks that apply to the alternative nonpharmacological treatment options should be taken into consideration.

RESUMO

OBJECTIVE: The use of ulipristal acetate (UPA) was indicated for the treatment of uterine fibroids. Following UPA suspension in March 2020, some patients presented worsening and required surgery. We aimed to identify patients at high-risk for undergoing surgery after UPA suspension. METHODS: We evaluated 85 women receiving intermittent UPA treatment until March 2020. Following UPA suspension, patients received other medical treatments or surgery. The clinico-pathological features were recoded and a quality of life health survey was completed by patients at the time of UPA suspension and at 6-months thereafter. RESULTS: After the suspension of UPA, 17 of the 85 patients receiving intermittent UPA (20%) required surgery, and 68 (80%) required other medical treatments. Patients who underwent surgery were younger and had greater fibroid volume. CONCLUSIONS: In our series, 20% of clinically stable patients receiving intermittent UPA required surgery following UPA suspension. These women should be considered for future medical strategies.

RESUMO

PURPOSE: Estradiol valerate/nomegestrol acetate (E2V/NOMAC) is a new combined oral contraceptive with a good tolerability profile and low drop-out rates, which was shown to improve menstrual-related symptoms. This study aims to evaluate its effectiveness in the control of symptoms and progression of disease in women with ovarian endomestriomas and deep infiltrating endometriosis (DIE). METHODS: This was a retrospective cohort study on 39 women with pelvic endometriosis treated with E2V/NOMAC. We assessed for each patient, at the beginning of treatment and after 6 months, the painful symptoms, through a global VAS (Visual Analogue Scale) index and the size of the greatest ovarian and/or deep infiltrating endometriotic lesions. RESULTS: After 6 months of treatment, a significant reduction was observed for the global VAS score for pain symptoms and for the mean size of ovarian endometriomas, whereas DIE lesions did not present significant changes in mean size. CONCLUSIONS: E2/NOMAC was effective in reducing pain symptoms associated with pelvic endometriosis and the size of ovarian endometriomas, whereas DIE lesions remained stable. This therapy could provide good results in the control of symptoms and disease progression in women with pelvic endometriosis.

RESUMO

AIM: To assess the efficacy and safety of long-term intermittent administration of 10-mg ulipristal acetate (UPA) for symptomatic uterine fibroids in Japanese women. METHODS: Open-label, noncomparative study (Japan Primary Registries Network identifier: JapicCTI-173737) conducted at 32 gynecological centers (November 2017-December 2019). Premenopausal women diagnosed with uterine fibroids associated with heavy menstrual bleeding received three 12-week courses of 10-mg UPA once daily. Amenorrhea, fibroid volume, endometrial histology, and safety were assessed. RESULTS: Of 155 patients enrolled, 140 received ≥1 dose of UPA and were analyzed. Across all courses, the rates of patients with amenorrhea for 35 days were >90%, and >99% of patients achieved uterine bleeding normalization. Median time to amenorrhea after each course started was 4-5 days; menstruation returned after treatment within a median of 25-27 days. Mean changes in fibroid volume from baseline were -21.5%, -31.4%, and -35.0% for Courses 1, 2, and 3, respectively. Patients experienced sustained improvements in anemia, pain, and quality of life during treatment. Most adverse events were mild/moderate in severity and decreased in frequency with each course. Seven serious adverse events (six patients) were reported; anemia, embolic cerebral infarction, and pituitary apoplexy (one patient each) were considered UPA-related. Nonphysiological changes in endometrial histology were transient and benign. No safety concerns were detected in hormone concentrations or liver function tests. CONCLUSIONS: Long-term administration of 10-mg UPA is effective for reducing symptoms associated with uterine fibroids in Japanese women. UPA was well tolerated and few safety concerns were reported.
