Liraglutide increases surfactant proteins (SPA & SPB) and angiotensin-converting enzymes (ACE & ACE2) expression in a rat model of acute lung injury by bleomycin

Fandino Juan , Toba Laura , Gonzalez-Nunez Maria , Diz-Chaves Yolanda , Gonzalez-Matias Lucas , Mallo Federico

Acute lung injury (ALI) is characterized by endothelial and epithelial damage, followed by inflammatory. Glucagon-like peptide-1 (GLP-1) is a gut-produced hormone with insulinotropic effects. GLP-1 receptor is expressed in the lung, and there implicated in the synthesis of surfactant proteins. We have previously shown that liraglutide (LIR), a GLP-1 receptor agonist, restores surfactant protein-B (SPB) levels, a limiting factor for survival, and also angiotensin converting enz...

Emotional behavior is modulated by liragutide in an age and gender manner in rats from food restriction mothers

Toba Laura , Fandino Juan , Gonzalez-Nunez Maria , Gonzalez-Matias Lucas , Diz-Chaves Yolanda , Mallo Federico

Food restriction (FR) of mothers during the perinatal period, can lead to disorders in emotional behaviors at offspring. GLP-1 may play a role in the regulation of anxiety-like behavior in rodents. The aim of this study was to asses if Liraglutide (a GLP-1 receptor agonist; LIR) given to pregnant rats may prevent the deleterious effects of FR in the anxiety-like behavior in pups at 21 days and two months of age males.Twenty-five pregnant Sprague-Dawley r...

Impact of the GH-receptor antagonist pegvisomant on mammographic breast density in postmenopausal acromegalic women

Muhammad Ammar , Ficarra Gianluca , Franck Sanne , Nazarri Elena , Tagliafico Alberto , Neggers Sebastian , Ferone Diego , Gatto Federico

Background: Acromegaly is a severe systemic condition characterized by elevated circulating levels of growth hormone (GH) and insulin-like growth factor I (IGF-I) and increased mortality and morbidity. The role of GH and IGF-I in mammary hyperplasia is well established and GH/IGF-I elevation has been hypothesized to favor neoplastic development. We recently demonstrated that premenopausal females with active acromegaly may display an increased mammographic breast density (MBD)...

Recalcitrant hypocalcaemia in a patient with post-thyroidectomy hypoparathyroidism and roux-en-y gastric bypass

Miguel Gonzalo Allo , Fernandez Elena Garcia , Librizzi Soledad , Diaz-Guerra Guillermo Martinez , Carranza Federico Hawkins

Introduction: Roux-en-Y gastric bypass (RYGB) places patients at an increased risk of hypocalcemia due to the reduction in calcium absorption (because the procedure bypasses the duodenum and jejunum) and vitamin D deficiency. Subsequent thyroid surgery increases the risk of severe hypocalcemia due to potential post-operative hypoparathyroidism. Only a few cases have been published before of this kind of treatment-challenging hypocalcaemia.Case report: We...

Association between peripheral vascular disease and other macrovascular and microvascular complications in diabetic patients

Miguel Gonzalo Allo , Fernandez Elena Garcia , Bracamonte Milagros Sierra , Diaz-Guerra Guillermo Martinez , Carranza Federico Hawkins

Introduction: Diabetes mellitus is a condition on the increase, carrying a high risk of macro and microvascular disease. Previous studies suggest a link between microvascular and macrovascular complications in diabetes. However, just a few studies have investigated whether the presence of peripheral vascular disease (PVD) is associated with other macrovascular and microvascular complications in diabetes patients. So, this was the aim of our study.Patient...

Diabetic kidney disease and its association with macrovascular disease in diabetic patients

Fernandez Elena Garcia , Miguel Gonzalo Allo , Villa Lucas Arroyave , Diaz-Guerra Guillermo Martinez , Carranza Federico Hawkins

Introduction: It is well known that diabetes confers a substantial burden of macrovascular disease. However, just a few studies have investigated the association between diabetic kidney disease (DKD) and cardiovascular disease. The purpose of this study is to investigate whether the presence of DKD is associated with macrovascular disease in diabetic patients.Patients and methods: 98 diabetic patients (48 males/50 females) were included in the study. DKD...

GH induces chemoresistance in human endometrial cancer cell lines involving ERK 1/2 and PKCdelta

Zuolo Giulia , Minoia Mariella , Gentilin Erica , Gagliano Teresa , Tagliati Federico , Zatelli Maria Chiara , Uberti Ettore degli

Background: Surgery is the main therapeutic option for advanced endometrial cancer; however, when disease relapses, chemotherapy is the only option. Chemoresistance is a very common phenomenon in these tumors. We previously demonstrated that GH protects breast cancer cells towards the cytotoxic effects of doxorubicin, inducing chemoresistance. Recent evidences show that endometrial cancer cells secrete GH, stimulating their own growth in an autocrine fashion.<p class="abst...

Obesity and metabolic syndrome in patients with primary acquired hypothyroidism undergoing chronic LT4 replacement therapy

Manzoni Giuseppina , Martucci Federico , Oltolini Alice , Villa Simona , Zimbalatti Dario , Lattuada Guido , Orsi Emanuela , Perseghin Gianluca

Hypothyroidism is a risk factor for obesity, central adiposity and ectopic fat accumulation. To assess whether this risk could be detected also in stable patients taking regularly the LT4 replacement therapy we assessed retrospectively the prevalence of metabolic syndrome (ATP III definition) and calculated the fatty liver index (FLI) and the visceral adiposity index (VAI) in patients attending our Outpatient Endocrinology Clinic because of known primary acquired hy...

Deletion of chromosome 1q24-1q32 and combined pituitary hormone deficiency type 4: Insight into the challenges of genotype-phenotype correlation

Giavoli Claudia , Ubertini Graziamaria , Giacchetti Federico , Rodari Giulia , Profka Eriselda , Cianfarani Stefano , Arosio Maura , Cappa Marco

Background: Interstitial deletions of the long arm of chromosome 1 are rare and classified as proximal or intermediate, the intermediate spanning bands 1q24–1q32. This region contains several genes, including LHX4, a LIM-homeodomain transcription factor essential in the early steps of pituitary ontogenesis. Indeed, mutations in the LHX4 gene are related to combined pituitary hormone deficiency type 4 (CPHD4, OMIM 602146).Aim: outline the impact of ...

Baseline IGF-I values influence the effect of rhGH therapy on fat mass: Short, medium and long term study on adults with GH deficiency

Profka Eriselda , Rodari Giulia , Giacchetti Federico , Draghi Alessandro , Arosio Maura , Giavoli Claudia

Background: One of the main effects of growth hormone therapy (rhGH) in the adult GH deficient patient (AGHD) is to positively modify body composition, with a reduction in fat mass (BF) and an increase in total lean mass (LM). However, the response to replacement therapy is highly variable and, contrary to what described in children, the potential predictive factors are not yet known.Aim of the study: To assess the impact of basal IGF-I levels on variati...
