RESUMO

The study was performed to compare the clinical effect of a hormone replacement therapy (HRT) with two different progestins. Postmenopausal women (PMW) with climacteric symptoms (CS) randomly received for 12 months orally, either placebo (n = 20), 1 mg estradiol (E) plus 0.5 mg noretisterone acetate (NETA; n = 40), or 2 mg drospirenone (DRSP; n = 40), a testosterone- and spironolactone-derived molecule, respectively. Weight (W) declined only during E/DRSP (p < 0.04 versus placebo). Fat mass (FM) decreased, similarly, during E/NETA and E/DRSP. Intracellular water (ICW) did not change, while extracellular water (ECW) decreased during E/DRSP (p < 0.0001) (p < 0.002 versus E/NETA). During E/NETA and E/DRSP, similar decreases were observed for insulin resistance (IR) by the homeostatic model assessment for IR (HOMA-IR) (p < 0.0001 versus placebo for both), systolic (p < 0.04 versus placebo for both) and diastolic (p < 0.002) blood pressure (BP). Lipids did not change. In comparison to placebo CS, by the Kupperman Index (KI), significantly declined (p < 0.0001) during E/NETA or E/DRSP. Menopause-specific Quality of Life (MENQoL) significantly declined versus placebo (p < 0.04) during both E/NETA and E/DRSP. In conclusion, differences between the two progestins are mainly limited to body composition (BC), where the addition of DRSP decreases ECW and body W (BW).

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

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.
