Introduction: Hypoaldosteronism can be induced by a deficit of aldosterone production (AldDef) or a mineralocorticoid resistance (MinRes). Experts have proposed to use hyperkalemia-based aldosterone values for this purpose. However, there is no a range of aldosterone values indicating one of this type of hypoaldosteronism. In 2008, Adam W. R.1 hypothesized that the factored aldosterone (FAldo) could be useful differentiating hypoaldosteronism secondary to MinRes fro...

Introduction: Hereditary phaeochromocytoma (PCC) and paraganglioma (PGL) account for 30–35% of cases and have some clinically relevant peculiarities.Material and methods: Retrospective, unicentric cohort study that included all genotyped patients (n=36, 27 with PCC and 9 with PGL) diagnosed at Hospital Clínico San Carlos (Madrid) between 1984 and 2013; 33% were germline mutation carriers (25% pseudohypoxic [PH] phenotype, 75% MAP-kinas...

Acquired Hypoaldosteronism may be caused by low circulating aldosterone levels (AD), resistance to mineralocorticoid action (MR), or a combination of both (CB). We describe the clinical/biochemical characteristics of these three types of hypoaldosteronism. Methods Retrospective review of a series of 177 patients with acquired hypoaldosteronism assessed by the Endocrinology Department of a tertiary teaching hospital from 2012 to 201...

Background: Parathyroidectomy is the only definitive treatment for primary hyperparathyroidism (PHPT). Identifying parathyroid adenomas (PA) before surgery is essential to perform minimally invasive surgery and to achieve higher cure rates.Methods: Retrospective study of patients with PHTP who underwent 18F-Fluorocholine Positron Emission Tomography- Computed Tomography (18FCH-PET-CT) between 2019 and 2021 at our center due to non-localization of PA or d...

Introduction: Clinically non-functioning pituitary adenomas (NFPA) are heterogeneous group. Some previous research has found that this type of pituitary adenomas may be smaller and have better prognostic in men. The aim of this study is to analyze if there are gender-related differences in NFPA.Material and methods: Retrospective study of patients with NFPA followed up in regional hospitals (Community of Madrid, Spain). All NFPA had molecular analysis. T...

Context: Primary hyperparathyroidism (PHPT) is a common endocrine disease, characterized by the chronic elevation of serum calcium (Ca) levels induced by a long-standing increase of PTH concentrations. PHPT includes mild-asymptomatic and symptomatic forms. Cinacalcet is effective in lowering serum Ca levels in PHPT, but is indicated solely in mild-asymptomatic PHPT meeting surgery criteria. Management of non-surgical mild-asymptomatic PHPT is still a debated issue.<p class...

Introduction: This study aimed to determine the timeframe to achieve hormonal normalization considering dosing patterns of Somatuline Autogel (SOM, lanreotide) used in clinical practice.Methods: From March 2013 to October 2013 clinical data from 62 patients with active acromegaly treated with SOM for &gE;4 months who achieved hormonal control (GH levels <2.5 ng/ml and/or normalised IGF1 on &gE;two evaluations) at 17 Spanish hospitals were collected i...

Medical treatment of acromegaly is currently performed through a trial-error manner using somatostatin receptor ligands (SRLs) as first-line drugs. Average SRLs response is seen in 50% of cases; subsequent drugs are indicated following clinical judgement. Some biomarkers either before or after surgical failure have been reported to predict SRLs response, including intensity in T2 weighted MRI, short acute octreotide test (sAOT), and different molecules such as SST2 and E-cadhe...

We previously described a short version of the acute octreotide test (sAOT) for predicting somatostatin receptor ligands (SRLs) response in patients with acromegaly1. In the present work, we prospectively reassess the sAOT ability to identify SRLs response in patients from the ACROFAST study using the current GH standards and control criteria and we also correlate sAOT values with E-cadherin tumor expression. Methods: Patients from the ACROFAS...
