Farnesoid X receptor (FXR) and Takeda G protein-coupled receptor 5 (TGR5) are interesting pharmacological targets for the treatment of liver and metabolic diseases. FXR-deficient mice on a high-fat diet (HFD) exhibit massive hepatic steatosis, necro-inflammation and fibrogenesis. Moreover, pharmacological activation of TGR5 in mice promotes protective mechanisms in biliary epithelial cells and inhibits hepatic and systemic inflammation. Thus, we hypothesized that a FXR/TGR5 du...

Giampietro Antonella , Chiloiro Sabrina , Mormando Marilda , Bima Chiara , Bracaccia Maria Elena , Piacentini Serena , Tartaglione Linda , Iacovazzo Donato , Bianchi Antonio , De Marinis Laura

Aim: To evaluate calcium and bone metabolism in a monocentric series of acromegaly patients (pts), treated with pegvisomant (PEG) alone or in association to long acting somatostatine analogs.Patients and methods: All pts with at least 24 consecutive months PEG treatment (alone or in combination with SSA) were enrolled. All pts had been tested at least twice/year for biochemical acromegaly-disease evaluation and annually for calcium metabolism and for bon...

Adrenal insufficiency during prednisolone treatment: need for cortisol replacement strategies in patients on long-term low-dose glucocorticoid treatment?

Borresen Stina Willemoes , Baslund Bo , Klose Marianne , Rasmussen AEse Krogh , Friis-Hansen Lennart , Hilsted Linda , Locht Henning , Hansen Annette , Hetland Merete Lund , Feldt-Rasmussen Ulla

Background: Patients on long-term glucocorticoid treatment are at risk of adrenal insufficiency during glucocorticoid treatment. The side effect can occur during glucocorticoid treatment if there is a mismatch between glucocorticoid requirements and production/intake. High-dose glucocorticoid treatment is often sufficient to overcome most stressful situations. A low-dose of 5 mg prednisolone/day is however, equivalent to 20 mg hydrocortisone, a dose often used as basal glucoco...

Glucocorticoid-induced adrenal insufficiency in prednisolone treated patients and how it relates to glucocorticoid dose and the duration of treatment

Dinsen Stina , Baslund Bo , Klose Marianne , Rasmussen AEse Krogh , Friis-Hansen Lennart , Hilsted Linda , Locht Henning , Hansen Annette , Feldt-Rasmussen Ulla

Objective: We aimed to assess the prevalence of glucocorticoid-induced adrenal insufficiency in prednisolone treated patients, and its relation to glucocorticoid dose and duration of treatment.Subjects and measures: As part of a larger study 48 patients with rheumatoid arthritis (33 women, aged 34–85 years) treated with a mean prednisolone dose of 7.0 mg (range 5–20 mg) per day, and a mean duration of treatment of 95 months (range: 6–360 m...

Nonalcoholic steatohepatitis as a novel player in metabolic syndrome-induced erectile dysfunction: an experimental study in the rabbit

Vignozzi Linda , Filippi Sandra , Comeglio Paolo , Cellai Ilaria , Rastrelli Giulia , Morelli Annamaria , Galli Andrea , Saad Farid , Mannucci Edoardo , Adorini Luciano , Maggi Mario

A pathogenic link between erectile dysfunction (ED) and metabolic syndrome (MetS) is now well established. Nonalcoholic steatohepatitis (NASH), the hepatic hallmark of MetS, is regarded as an active player in the pathogenesis of MetS-associated cardiovascular disease (CVD). This study was aimed at evaluating the relationship between MetS-induced NASH and penile dysfunction. We used a non-genomic, high fat diet (HFD)-induced, rabbit model of MetS, and treated HFD rabbits with t...

IGF1 response to rhGH in adult GHD: role of GH receptor (GHR) isoforms

Bianchi Antonio , Tartaglione Linda , Giampietro Antonella , Milardi Domenico , Angelini Flavia , Mormando Marilda , Lugli Francesca , Piacentini Serena , Grande Giuseppe , Iacovazzo Donato , Chiloiro Sabrina , Pontecorvi Alfredo , Marinis Laura De

The IGF1 response to recombinant human growth hormone (rhGH) showed some individual variability and the responsible factors for this behavior remain unknown. Some studies have emphasized the possible role of isoforms of the GH receptor (GHR), showing conflicting results.Therefore, we investigated the possible influence of the isoforms of the GHR to the diagnosis of GHD and in determining adult hormone replacement therapy responsiveness.<p class="abst...

Association between an AMH promoter polymorphism and serum AMH levels in PCOS patients

Introduction: Polycystic ovary syndrome (PCOS), the most common endocrine disorder in women of reproductive age, is diagnosed based on three criteria, including a polycystic ovarian morphology. Moreover, women with PCOS have elevated serum Anti-Müllerian Hormone (AMH) levels, a hormone known to correlate with follicle number. In addition, AMH production per follicle is suggested to be higher in PCOS. Little is known about AMH gene regulation. Hence, this study aims to inv...

Objective: To investigate comorbidity rate, symptoms, overall morbidity, medication useand use of health care services among women with polycystic ovary syndrome (PCOS).Design: Community-based prospective cohort study.Patients: Womenreporting oligo/amenorrhea and hirsutism at age 31 and/or PCOS diagnosis by age 46 (n = 280) and controls without PCOS related symptoms or diagnosis (n = 1573) in the Northern ...

High glucose induces hypogonadotropic hypogonadism by interfering with GPR54 signaling in the preoptic area of the hypothalamus

Morelli Annamaria , Vignozzi Linda , Erica Sarchielli , Comeglio Paolo , Filippi Sandra , Rastrelli Giulia , Maneschi Elena , Cellai Ilaria , Barbara Vannelli Gabriella , Maggi Mario

The metabolic syndrome (MetS) is a clustering of metabolic and cardiovascular risk factors, having in insulin resistance the key element. In males, MetS is also associated to hypogonadism. We recently found that high fat diet (HFD)-induced MetS rabbits also developed hypogonadotropic hypogonadism, showing a reduced immunopositivity for gonadotropin relasing hormone (GnRH) in the hypothalamus. In this study, we investigated the pathogenetic link between Mets components and the ...

The FXR agonist obeticholic acid normalizes lipid droplet and triglyceride handling in visceral adipose tissue preadipocytes from a non-genomic rabbit model of metabolic syndrome

Maneschi Elena , Vignozzi Linda , Morelli Annamaria , Mello Tommaso , Filippi Sandra , Cellai Ilaria , Comeglio Paolo , Sarchielli Erica , Calcagno Alessandra , Vettor Roberto , Vannelli Gabriella Barbara , Adorini Luciano , Maggi Mario

Liver and visceral ectopic fatty tissue disposition is a major metabolic derangement leading to type 2 diabetes, hypertension, dyslipidaemia, recapitulated in the metabolic syndrome (MetS). We have demonstrated that the selective FXR agonist obeticholic acid (OCA, INT-747) ameliorates the metabolic profile and reduces visceral adipose tissue (VAT) in a high-fat diet (HFD)-induced rabbit model of MetS. We now report the effects of OCA treatment in HFD (0.5% cholesterol and 4% p...
