RESUMO

This observational study was conducted in premenopausal women who presented themselves at the Obstetrics and Gynecology Department of the University Hospital of Cagliari (Italy), for heavy menstrual bleeding (HMB) dependent on uterine myomas. After a screening visit, 19 women without contraindications to ulipristal acetate (UPA) treatment, were included in the study that envisaged 12 months of observation in which each subject was asked to assume UPA (tablet of 5 mg, ESMYA®, one tablet a day for 3 months: first cycle) two menstrual cycles of interruption and a second ESMYA® cycle, followed by 3 months of observation (third follow-up month, visit 4). The significant decrease of myoma volume, diagnosed after the first ESMYA® cycle, persisted until the visit 4. The HMB significantly decreased during the ESMYA® treatment and persisted until visit 4. The quality of life (QoL), evaluated with the questionnaire SF-36, significantly improved during the study. The values of estradiol (E2), biochemical parameters of bone metabolism, as well as those of lumbar and hip bone mineral density, did not change during the study in comparison with basal levels. The efficacy of two repeated ESMYA® cycles to treat uterine myomas and their related symptoms improves the QoL without interfering with bone health.

RESUMO

INTRODUCTION: The medical strategy to antagonize myoma size and related-symptoms is to reduce estrogen and progesterone activity on myomas. This can be obtained with the GnRH agonist (GnRHa) or with compounds that antagonize progesterone stimulatory activity on myomas. Selective progesterone receptor modulators (SPRMs) bind progesterone receptor (PR), leading to both agonist and antagonist effects. The result of SPRMs's action is tissue-specific and it depends on the particular affinity and strength of each SPRM. Area covered: Ulipristal acetate (UPA) is the first SPRM registered for myoma treatment. UPA reduces heavy uterine bleeding within 7 days from the onset of treatment, whereas a longer time is required with GnRHa treatment. Vilaprisan is a novel powerful SPRM. Phase I and II studies give encouraging results on the efficacy of vilaprisan at different doses. Like other SPRMs, vilaprisan induces benign changes of endometrium (PR modulator-associated endometrial changes, PAECs). These disappear as treatment is discontinued. Unlike GnRHa treatment, neither UPA nor vilaprisan induce hypoestrogenism and associated symptoms. Phase III studies are ongoing to confirm efficacy and safety of vilaprisan in long-term treatment of symptomatic fibroids. Expert opinion: It is fundamental to underline the rapidity of action (only 3 days) in the control of myoma-related bleeding.

RESUMO

The vaginal immune system (VIS) is the first defense against antigens recognized as foreign. Substances capable of locally activating the VIS could be a valid strategy to treat vulvo-vaginal infections (VVI), caused by changes in the vaginal ecosystem, such as bacterial vaginosis (BV), vulvo-vaginal candidiasis (CA), and mixed vaginitis (MV). Bacterial lysates, obtained by crushing bacterial cultures, exert immuno-modulatory activities. The parietal fraction from Propionibacterium acnes is a patent of Depofarma (MoglianoVeneto, Italy). The preparation that associates such fraction to hyaluronic acid and polycarbophil is a registered trademark, commercially available in Italy as vaginal gel, Immunovag®. The study aimed to evaluate whether a 5-day-treatment with Immunovag® improves the symptoms and signs of VVI, in 60 women with Gardnerella vaginalis (GV), 154 with CA, 95 with MV, diagnosed with vulvar vaginal swab (VVS), and in 283 with BV, diagnosed with the Amsel criteria. At the end of the treatment (visit 2), the symptoms and signs of VVI disappeared in a significant number of subjects (χ2p < .02 vs pre-treatment) in all VVI groups, and their intensity was significantly (p < .0002) reduced in the subjects in which they were still present. Immunovag® represents a valid treatment of VVI induced by changes in the vaginal ecosystem.

RESUMO

We investigated whether a formulation containing vitamins and minerals (vit&min) could improve the worsening of mood changes occurring after delivery ("a.d."). The study was performed in 552 healthy non-anaemic puerperal women ("p.w") without risk factors for puerperal depression ("p.d"). They were at their first full-term pregnancy, and spontaneously delivered healthy newborns. The Edinburgh Depression Postnatal scale (EPDS) evaluates the psychological status of "p.w". EPDS was administered the 3rd (visit 1), 15th (visit 2) and 30th (visit 3) day "a.d.". An EPDS >12 indicates a major susceptibility to "p.d". At the same time intervals, haemoglobin, iron and ferritin (haematological parameters) levels were evaluated. After visit 1, the subjects were randomized to vit&min treatment (group A; N.274) or to calcium/vitamin D3 treatment (group B; N.278). In both groups haematological parameters significantly increased without differences between the groups. EPDS score improved in both groups, but in the group A, the EPDS decrease was significantly larger (p < 0.05) in comparison to the group B. This effect is mainly evident in subjects with a basal EPDS ≥ 12. An early examination of psychological condition could select "p.w." with a high susceptibility to neuronal changes occurring postpartum. Vit&min favourably modulates brain functions antagonizing the evolution to "p.d".

RESUMO

INTRODUCTION: Progesterone (P), and its receptors (PRs), play a key role in uterine leiomyoma growth. Selective progesterone receptor modulators exert mixed antagonist and agonist effects on the PRs. Mifepristone, a PR-antagonist, reduces leiomyoma volume and related symptoms. Ulipristal acetate (UPA) exerts a potent antiprogestin activity, with less antiglucocorticoid activity compared to mifepristone. This property provides potential advantages for long-term use. AREAS COVERED: This paper focuses on the effect of UPA on leiomyoma's growth and related symptoms in women. The authors also evaluate UPA's efficacy in reducing leiomyoma's size and menorrhagia in Phase II/III trials. EXPERT OPINION: In the authors' opinion, UPA (5 mg/day) over 3 months can be used to plan the surgery in women with symptomatic leiomyomas. The tolerability and the safety of treatment over a period longer than 3 months have to be evaluated. The results of the follow-up treatment suggest that further studies could successfully evaluate the efficacy and the tolerability of intermittent 3-month courses of treatment.

RESUMO

BACKGROUND: Chlormadinone acetate (CMA) is a progestin compound similar to progesterone, with antiandrogenic properties. In healthy eumenorrheic women, it was demonstrated that the monophasic estroprogestin formulation containing CMA (2 mg) plus ethinyl estradiol (EE) (30 mcg) (EE30+CMA) is efficacious both in reducing hyperandrogenic symptoms, fat mass and in improving lipoprotein panel, without changes in insulin-glucose metabolism. These metabolic properties are important for women affected by polycystic ovary syndrome (PCOS) in whom there is a predisposition to insulin resistance. STUDY DESIGN: We studied whether in young nonobese women with PCOS (15 subjects, EE30+CMA-PCOS group) a six-cycle treatment with EE30+CMA can reduce androgen levels, androgen bioavailability and the score of hirsutism and acne, and modify glucose-insulin metabolism evaluated by the oral glucose tolerance test and the body composition evaluated by bio-impedenziometry. These parameters were evaluated before (first visit) and during the sixth cycle of EE30+CMA (second visit). All the results were compared with those of a matched-age-group of nonobese PCOS women (15 subjects, no OC-PCOS group) evaluated before (first visit) and after six menstrual cycles in which they did not use any drug or oral contraceptive (second visit). RESULTS: In the EE30+CMA-PCOS group women, androgen levels and bioavailability, hirsutism and acne score were significantly lower at the second than at the first visit, whereas they did not change in no OC-PCOS group. At the second visit, in both groups, glucose-insulin metabolism and body composition parameters were not affected. CONCLUSIONS: A six-cycle treatment with EE30+CMA is efficacious in nonobese PCOS women to improve hyperandrogenic symptoms, without negative interferences both on body composition and on insulin-glucose metabolism.

RESUMO

BACKGROUND: We aimed to evaluate whether a six-cycle treatment with oral contraceptive containing 30 mcg of ethinylestradiol (EE2) plus 2 mg of chlormadinone acetate (CMA) (EE2+CMA) alters body weight (BW) and body composition of healthy young women with normal menstrual cycles. The results in treated subjects were compared to those obtained in nontreated women as control. STUDY DESIGN: Multifrequency bioelectrical impedance analysis (MF-BIA) was performed in 48 healthy young women during the follicular phase of their menstrual cycle. Of this group, 24 women were treated with EE2+CMA, and the MF-BIA was repeated at the third and sixth cycle of treatment. The remaining 24 women were submitted to the same examinations after three and six cycles without any treatment. Total body water (TBW), intracellular water (ICW), extracellular water (ECW), fat mass (FM) and fat-free mass (FFM) were calculated. Waist-to-hip ratio (WHR), BW, blood pressure, and the plasma concentrations of electrolytes were also measured at each visit. RESULTS: Mean FM significantly (p<.05) decreased in the EE2+CMA group from basal levels of 14.23+/-1.03 to 13.51+/-1.09 and 12.71+/-1.02 kg at the third and sixth cycle of treatment, respectively. Stable values were seen in the control group. During observation, other parameters (BW, WHR, TBW, ECW, ICW, FFM) remained unchanged in all subjects. CONCLUSIONS: EE2+CMA reduces FM without altering TBW, ICW, ECW. These preliminary results suggest that progestational activity of CMA could balance both fluid retention and weight gain elicited by EE2.

RESUMO

PURPOSE: Seizure exacerbation in catamenial epilepsy (CE) is associated with the decrease in progesterone secretion and increase in estradiol secretion during the premenstrual period. Moreover, experimental evidence suggests that tetrahydrodeoxycorticosterone (THDOC), a positive modulator of the type A receptor for gamma-aminobutyric acid (GABA), and dehydroepiandrosterone sulfate (DHEAS), a negative modulator of this receptor, might play a crucial role in modulating seizure frequency during the menstrual cycle. Following these studies it seems of interest to investigate possible variations, among other hormonal parameters, of THDOC and DHEAS in CE patients. METHODS: The serum concentrations of progesterone (P4), pregnenolone, allopregnanolone (AP), THDOC, DHEAS, cortisol, and DHEAS/cortisol ratio were measured throughout the menstrual cycle at the 7th, 11th, 15th, 19th, 23rd, and 27th day from the onset of spontaneous menstrual blood loss in young premenopausal women with CE (n = 17) and age-matched controls (n = 13). RESULTS: At each time of the study, the serum concentration of THDOC and the DHEAS/cortisol ratio were lower (p < 0.05) in women with CE than in control women. The concentrations of P4, pregnenolone, and AP did not differ between the two groups of subjects. CONCLUSIONS: The reduced serum concentration of THDOC and the reduced DHEAS/cortisol ratio detected throughout the menstrual cycle in women with CE might play a role in CE. Moreover, the peculiar pattern of CE seizure exacerbation might suggest that these neuroendocrine variations are worth investigating in other epileptic syndromes, particularly in those characterized by relevant and uncontrolled variations in seizure frequency.

RESUMO

We investigated whether pregnancy could modify psychological symptoms and whether neuroactive steroids which exert an anti-anxiety effect by acting on the gamma-aminobutyric acid (GABA)-A receptors, are modified during pregnancy in young healthy women. Healthy volunteer women in the Department of Obstetrics and Gynecology at Cagliari University participated in the study. They were divided into women with low (group 1, seven subjects) and high (group 2, seven subjects) psychological score by SCL-90 psychometric scale. Age, body mass index and physiological status of pregnancy did not differ between the groups. The subjects were studied before pregnancy during the follicular phase (FP), and the luteal phase (LP) of the menstrual cycle (MC) and four times during pregnancy (at 14th, 22nd, 30th, and 38th week). SCL-90 psychometric scale, circulating levels of progesterone (P4), 3alpha-hydroxy-5alpha-pregnan-20-one (allopregnanolone, AP), 3alpha,21-dihydroxy-5alpha-pregnan-20-one (allotetrahydrodeoxy-corticosterone, THDOC), cortisol and DHEAS were assayed at each visit. The SCL-90 global score and the intensity of psychological symptoms differ between the groups, but within each group they did not change both during MC and during pregnancy. The DHEAS and cortisol levels did not differ between the groups. DHEAS did not change during the study, whereas cortisol levels increased during pregnancy in both groups. Progesterone, AP, and THDOC levels were higher during LP than during FP and further increased during pregnancy, without any difference between the groups. In conclusion, pregnancy does not seem to interfere with the psychological status of healthy women independently of the psychological basal score. Some neuroactive steroids with anxiolytic activity seem to increase during pregnancy depending on placental function. Their increase could represent some kind of protection against maternal anxiety and stress due to concerns about the pregnancy outcome.
