Effect of oral contraceptives containing estradiol valerate vs. ethinyl estradiol combined with dienogest on biomarkers of coagulation – a randomized clinical trial

Haverinen Annina , Luiro Kaisu , Szanto Timea , Kangasniemi Marika , Hiltunen Leena , Sainio Susanna , Piltonen Terhi , Lassila Riitta , Tapanainen Juha , Heikinheimo Oskari

ObjectiveTo compare the effects of combined oral contraceptives (COCs) containing estradiol valerate (EV) and dienogest (DNG) with ethinyl estradiol (EE) and DNG on biomarkers of coagulation: thrombin generation (TG), prothrombin fragments F1+2 (F1+2) and D-dimer (D-Di). A DNG-only preparation was included as a control.BackgroundCOC use increases the risk of venous thromboembolism (VTE) 2-6-fold compa...

Central diabetes insipidus following immunization with BNT162b2 mRNA Covid-19 vaccine

Bouca Bruno , Roldao Marisa , Bogalho Paula , Cerqueira Luis , Silva-Nunes Jose

Introduction: The endocrine complications of COVID-19 remain largely unknown. Cases of central diabetes insipidus (CDI) have been reported after COVID-19, with hypophysitis being the most likely cause. COVID-19 vaccines potential adverse effects may mimetize some of these complications. We present a case of a woman who developed CDI one week after the 2 nd dose of BNT162b2 mRNA COVID-19 vaccine.Case Report: Female patient, 37 years old, with rheumatoid a...

Novel steroidal derivatives preventing prostate dihydrotestosterone synthesis

Cabeza Marisa , Carlos Lopez-Lezama Juan , Soriano Juan , Valencia-Islas Norma , Heuze Yvonne

It is well-known that the increase of intraprostatic levels of 5α-dihydrotestosterone is related to the development of prostatic pathologies such as benign prostatic hyperplasia and prostate cancer. So finasteride and dutasteride-based therapies have been used to improve these diseases. These drugs are potent inhibitors of the enzyme 5α-reductase, which is found in the androgen-dependent tissues. This enzyme is responsible for converting testosterone into dihydrotest...

Faecal microbiota signature in hypothyroid patients with refractoriness to levothyroxine treatment

Virili Camilla , Capriello Silvia , Stramazzo Ilaria , Filardo Simone , Pietro Marisa Di , Sessa Rosa , Centanni Marco

Despite an accurate management, in about 20% of hypothyroid patients showing an increased need for oral levothyroxine (LT4), the leading cause of treatment refractoriness remains unknown. Some studies hypothesized the relationship between gut microbiota composition and thyroid homeostasis, but the possible involvement of microflora in the efficacy of LT4 treatment has not been evaluated yet, and this represents the aim of our study. We examined the faecal microflora compositio...

Activity of pure, novel and non-steroidal molecules as inhibitors of AK1C enzyme

Cabeza Marisa , Piermattey Johan Jhoan H. , Gaitán-Ibarra Ricardo , Soriano Juan , Heuzr Yvonne

Prostate and seminal vesicles are male accessory sex glands secreting fluids that, together with sperm, form the semen. Clear evidence indicating these organs depend on androgens was found the men suffering hypogonadism because, in them, the function of these glands decreases markedly. Because prostate and seminal vesicles are androgen-dependent organs, they have been used as a model to test antiandrogenic drugs in different animal species.The objective ...

Clinical and hormonal variables to predict bone mineral density loss in anorexia nervosa patients

Gonzalez Amalia , Varsavsky Mariela , Fernandez Ines Luque , Leyva Socorro , Palma Moya Mercedes , Soto Marisa Fernandez

Objective: Anorexia nervosa (AN) is often associated with severe mineral bone loss and increased risk of fractures. The objective of this study was to assess the bone mineral density (BMD) in patients with AN and its relationship with different anthropometrics, clinical and hormonal parameters.Patients and methods: We evaluated 47 women with AN according to criteria of DSM-IV. The anthropometrics variables measured were: weight (kg) height (m), BMI (kg/m...

Cell line derived from glioblastoma synthesizes steroid hormone. Effect of enzyme inhibitors

Garcia Luis Manuel Pinacho , Valdez Ricardo A , Navarrete Araceli , Cabeza Marisa , Segovia Jose , Romano Marta C

Glioblastoma (GB) is the most aggressive primary brain tumor, the survival rate is low because of a high prevalence of recidives. The incidence of GB in the adult population is 50% higher in men than in women, which suggest a role of steroid hormones in it is development. Information on GB as a steroidogenic tissue is poor. The objectives of this study were: 1, to investigate the capacity of a human GB cell line to synthesize sex steroids and corticosteroid metabolites, and 2,...

Effect of bariatric surgery on free vitamin D3 levels

Marques-Pamies Montserrat , Pellitero Silvia , Granada Marisa , Santillan Cecilia Soledad , Lopez Maria , Puig-Domingo Manel

Total vitamin D levels are decreased in obese patients probably due to an increased volume of distribution mechanism. Recently introduced direct assays allow the measurement of free-vitaminD3 levels (fvitD3). Few data are available regarding fvitD3 levels in obese people and the effect of bariatric surgery upon its circulating concentration. We aimed to evaluate fvitD3 in a cohort of obese patients before and after bariatric surgery treatment and its relationship to phosphocal...

Pre and post-surgical pituitary dysfunction increase the risk of mortality in patients with non-functioning pituitary tumors: A long-term cohort study

Beyhart Arturo , Mariaca Karla , Salva-Crespi Valeria , Diaz Catalan Daniela , Aldecoa Iban , L Olondo Maria , Sanchez-Dalmau Bernardo , Alobid Isam , Halperin Irene , Mora Mireia , Ensenat Joaquim , Alexandra Hanzu Felicia

Background: Long-term studies evaluating mortality in patients with non-functioning (NF) pituitary tumors (PitNets) are limited, although standardized mortality ratios (SMR) in these patients are reported to be higher than that of general population. There is also no agreement on predictive factors associated to the increased mortality apart from age at diagnosis and glucocorticoid substitution therapy dose.Objective: To assess long-term mortality and as...

Cardiovascular Events and Gender-Affirming Hormone Therapy, 10 Years of Follow-Up

Mariaca Riveros Karla , Martinez Veronica , Claro Maria , Sola Clara , Aranda Gloria , Alexandra Hanzu Felicia , Ortega Emilio , Orois Aida , Gomez Esther , Godas Teresa , Mateu Salat Manel , Halperin Irene , Mora Mireia

Objectives: Most transgender persons (0.3-0.5% of total population) are under gender-affirming hormone therapy (GAHT). Several studies have reported an increased morbimortality due to cardiovascular events (CVE), infectious disease and suicide. However, these studies were made on small populations and short follow up. We evaluated the changes on anthropometric variables, risk factors for cardiovascular diseases (CVD) and CVE at 5 and 10 years of follow up in a transgender popu...
