The Spanish acromegaly registry (REA) is an online epidemiological database created in 1997 to collect clinical and biochemical data of patients with acromegaly followed in Spain.Aim: To study trends in acromegaly treatment over time in Spain.Methods: REA is an online database in which registered endocrinologists collect data from all acromegalic patients seen at their practices in Spain. In the last year the neuroendocrine group o...

Prediction of the biological behavior in non-functioning pituitary adenomas (NFPA) according to morphological criteria is highly inaccurate. Reliable prognostic molecular markers could be useful in providing guidance in NFPA post-surgical follow-up.Aim: To identify differentially expressed genes between aggressive and non-aggressive NFPAs and to assess their prognostic value.Methods: Samples analyzed were selected from a series of ...

Introduction: Previous results of our group, presented in the ECE last year, showed a lower gene expression of proconvertase PC1/3, involved in the processing of POMC, in silent corticotroph tumors (sCT) than in functioning ones (fCT), overall and in microadenomas. The aim of the present study was to quantify the protein expression of convertases involved in the processing of POMC (PC1/3) and in the degradation of ACTH (PC2, CPE and PAM) in a series of CT.</p...

Introduction: Silent corticotroph tumours (SCT) are a pituitary tumours (PT) subtype of corticotroph lineage that do not clinically express Cushing disease. Inmunohistochemical (IHC) studies reveal no differences between SCT and functioning corticotroph tumours with Cushing Syndrome (FCT). However, the silencing mechanisms of this type of tumours are not fully understood.Aim: In an important series of SCT, to sequence the POMC gene and quantify ...

Introduction: Pituitary abscess (PA) is a rare condition, representing less than 1% of pituitary lessions. Only around 200 cases have been reported in the scientific literature. Preoperative diagnosis is often challenging due to nonspecific clinical and radiological manifestations.Materials and methods: Retrospective descriptive cohort study. We analyze demographic and clinical variables, hormonal involvement, recurrence, type of surgery and antibiotic t...

Methods: Descriptive retrospective study among patients who underwent ETPS for ACTH-secreting pituitary adenomas performed by the same surgical team from January/2013 to January/2017.Results: 27 ACTH-secreting pituitary adenomas operated via ETPS. 20 (74.1%) were women, median age at surgery was 43.25 [29.65–61.59] years and median follow-up was 3.13 [1.6–6.69] years. Presurgically, 25 (92.59%) patients recieved drugs for control cortisol hyper...

Methods: We conducted a retrospective descriptive study including 67 patients with non-functioning pituitary adenomas surgicaly removed via ETPS beetwen January/2013 to January/2017.Results: Among 67 patients with non-functioning pituitary adenomas surgicaly removed via ETPS 44 (65.67%) were men. 52 (77.61%) patients recieved their first surgery, 14 (20.9%) had been operated one time before and 1 (1.49%) had been operated two times. Every patient reopera...

Background: Conventional therapy for chronic hypoparathyroidism (cHP) is often unable to maintain stable normal serum calcium (Ca) levels for a full 24 h, to control symptoms, to prevent the detrimental long-term effects on the kidney and to preserve normal bone architecture. Eneboparatide (AZP-3601) is a novel 36-amino-acid peptide specifically designed to activate the R0 conformation of the PTH receptor 1, that results in a prolonged calcemic response and a sustai...

Background: Conventional therapy with oral calcium (Ca) and active vitamin D (vitD) supplementation for chronic hypoparathyroidism (cHP) can induce or aggravate hypercalciuria and may lead to detrimental long-term renal complications. Eneboparatide (AZP-3601) is a novel 36-amino-acid peptide with a short half-life designed to activate the R0 conformation of the PTH 1 receptor which produces a prolonged calcemic response. This phase 2a study examined the effects of e...

Objectives: The transition from the paediatric age to the adult is a particularly vulnerable period in patients with metabolic congenital diseases (mcd). In andalusia two adults’ units exist (seville and malaga) for the follow-up of these patients. Our aim in this study was to evaluate the current series of attended patients.Material and methods: We evaluated all patients transferred to the adult units since 2008. The clinical records were analyzed ...
