Somatostatin analogues-induced diabetes mellitus in acromegalic patients reverts after drug withdrawal: a long-term study

Cappellani Daniele , Urbani Claudio , Sardella Chiara , Marconcini Giulia , Marcocci Claudio , Rossi Giuseppe , Bogazzi Fausto

Context: Therapy with somatostatin analogues (SSAs) may have deleterious effects on glucose metabolism in patients with acromegaly, often leading to development of diabetes mellitus (DM).Aim of the study: To evaluate whether DM, which developed during therapy with SSAs, may revert after drug withdrawal and cure of acromegaly with pituitary adenomectomy.Design: Retrospective cohort study, in a tertiary referral center.<p class="...

Estradiol reverts the impairment of the natriuretic peptide system in a menopause-associated obesity model

Belo Najara , Reis Adelina , Sairam Malur

The follicle-stimulating hormone receptor knockout (FORKO) female mouse provides a useful model to examine the role that lack of estrogen plays in the development of obesity and hypertension in postmenopausal women. Estrogen increases circulating levels of atrial natriuretic peptide (ANP), a hormone with renal and cardiovascular effects. It has been shown that atrial natriuretic peptide (ANP) is a potent stimulator of fat cell lipolysis in addition of its well established effe...

Body weight loss reverts obesity-associated hypogonadotropic hypogonadism: a meta-analytic study

Corona Giovanni , Rastrelli Giulia , Monami Matteo , Saad Farid , Luconi Michaela , Lucchese Marcello , Sforza Alessandra , Forti Gianni , Mannucci Edoardo , Maggi Mario

Introduction: Few randomised clinical studies have evaluated the impact of diet and physical activity on testosterone levels in obese men with conflicting results. Conversely, studies on bariatric surgery in men generally showed an increase in testosterone levels. The aim of the present study is to perform a systematic review and meta-analysis of available trials on the effect of body weight loss on sex hormones levels.Methods: An extensive Medline searc...

Potential role of vitamin D in restoring sensitivity to mTOR inhibitors in hepatocellular carcinoma (HCC): 1,25(OH)vitamin D (VitD) reverts everolimus (EVE) resistance in a hcc cell line

Pivonello Claudia , Provvisiero Donatella Paola , Negri Mariarosaria , Gennaro Gilda Di , de Angelis Cristina , Simeoli Chiara , Galdiero Giacomo , Martino Maria Cristina De , Colao Annamaria , Pivonello Rosario

HCC is a difficult-to-treat- cancer with poor prognosis. Despite EVOLVE-1 trial demonstrated that EVE did not improve overall survival in molecularly and clinically unselected patients with advanced sorafenib resistant HCC, in selected patients, the established antitumor effect of EVE could make this drug a potential adjuvant therapy. Unfortunately, the acquired EVE resistance due to the tumour adaptation to chronic drug use is a current challenge. VitD has been deemed as pote...

Potential role of vitamin D in restoring sensitivity to mTOR inhibitors in hepatocellular carcinoma (HCC): 1,25(OH)vitamin D (VITD) reverts everolimus (EVE) resistance in a HCC cell line

HCC is a difficult-to-treat- cancer with poor prognosis. The recent EVOLVE-1 trial demonstrated that EVE did not improve overall survival in molecularly and clinically unselected patients with advanced HCC resistant to sorafenib treatment. In selected patients, the well-established antitumor effect of EVE could make this drug a potential adjuvant therapy. Unfortunately, the acquired resistance to this molecule due to the tumor adaptation to chronic drug use is a current challe...

Characteristics and management of hospitalized patients with hyponatremia in an endocrinology department

Sanz Revert Pablo , Carlos Ferrer Garcia Juan , Sanchez Juan Carlos , Garcia Blasco Lourdes

Hyponatremia is the electrolyte disorder most commonly encountered in hospitalized patients. The prevalence and characteristics of patients admitted with hyponatremia are analyzed in this study.Description of methods/design: cross sectional study is carried out at the University General Hospital of Valencia, comprising a population of 350,000. 681 of the 30676 patients admitted during the period from January 2014 to December 2015 had hyponatremia include...

Effect of pegvisomant on glucose metabolism

Aznar S , Boix E , Revert P , Moreno O , López-Maciá A , Picó A

Aim: To quantify the effect of pegvisomant on glucose homeostasis, lipid profile and disease activity in acromegaly.Methods: 5 Patients with active acromegaly after surgery, radiotherapy and somatostatin analogs were included. Somatostatin analogs were withdrawn 6 weeks before starting pegvisomant and it was initially administered subcutaneously at doses of 10 mg daily. Doses were progressively increased every 3 to 4 weeks until IGF1 normalization. Gluco...

Selective Cyclo-oxygenase 2 inhibitors revert chemoresistance In Medullary thyroid carcinoma by a mechanism mediated by P-gp and PGH2

Zatelli MC , Luchin A , pICCIN D , Tagliati F , Bottoni A , Vignali C , Bondanelli M , degli Uberti EC

Medullary thyroid carcinoma (MTC) is a malignant tumour deriving from parafollicular C cells, with a highly chemoresistant phenotype. Failure of medical therapy has been ascribed, at least in part, to multi drug resistance (MDR1) gene over-expression. MDR1 encodes for a transmembrane glycoprotein, P-gp, which hampers intracellular accumulation of cytotoxic drugs. It has been demonstrated that P-gp expression and function depend on cyclo-oxygenase 2 (COX-2) expression, which is...

Hyperparathyroidism healing in patients treated for hyperaldosteronism: three cases

Blasco Lourdes Garcia , Garcia Juan Carlos Ferrer , Torrens Mercedes Tolosa , Revert Pablo Sanz , Alacid Cristian Marco , Juan Carlos Sanchez

Introduction: Hyperaldosteronism usually presents with hypertension and hypokalemia; however, there is recent evidence of a relationship with the parathyroid hormone. There are different theories to try to explain this relationship. Hyperaldosteronism treatment is medical or surgical depending upon etiology. We present three cases in which treatment solely for hyperaldosteronism also cured hyperparathyroidism.Materials and methods: We report three patien...

Gonadotropin releasing hormone analogue in cyclophosphamide-induced premature gonadal failure prevention

Revert Paula , Moreno Oscar , Lopez-Gomez Juan Miguel , Sivera Francisca , Martinez Sandra , Perdiguero Miguel , Pascual Eliseo , Pico Antonio

Background: Premature ovarian failure (POF) due to cyclophosphamide (Cyc) therapy is well documented in systemic lupus erythematosus (SLE) patients. Studies show that the use of gonadotropin releasing hormone (GnRH) analogues appears to protect women from POF. We present our experience in SLE patients treated with triptorelin.Methods: Observational study of 15 women diagnosed of SLE who have received concomitant treatment with Cyc and GnRH analogues (tri...
