Introduction: Adult-onset autoimmune diabetes (AID) has two different phenotypes: classic type 1 diabetes mellitus (T1DM), with insulin requirement just after diagnosis, and latent autoimmune diabetes in adults (LADA). According to the Immunology of Diabetes Society, LADA diagnostic criteria are: age of onset of 30 years or more, any islet autoantibody, absence of insulin requirement for at least 6 months. The purpose of this study is to characterize patients with AID followed...

DNA methylation is an epigenetic mechanism of gene regulation that can be modified during intrauterine and postnatal life. Pregnant women with polycystic ovary syndrome (PCOS) present elevated androgen and insulin levels, which can affect the DNA methylation pattern of their offspring. Then, we studied the global DNA methylation pattern (GDNAm) in daughters and sons born to PCOS women compared to controls. Daughters (99 born to PCOS and 87 born to control women) and sons (74 b...

Introduction: The European Society of Endocrinology Clinical Practice Guideline defines follow-up recommendations for AI based on the 1 mg overnight dexamethasone suppression test and the presence of associated comorbidities. Follow-up is not recommended for AI presenting serum cortisol levels post dexamethasone ≤1.8 μg/dl neither those presenting serum cortisol levels post dexamethasone between 1.9–5 μg/dl (defined as ‘possible autonomous cortisol se...

Introduction: Primary aldosteronism (PA) is the principal cause of arterial hypertension potentially treatable. The diagnosis is dependent of tests to identify patients who will benefit most with surgical treatment. ACTH stimulation test (AST) has been described as a useful confirmatory test, potentially identifying bilateral disease in patients without adrenal tumors.Aim: Evaluate the AST in patients with hypertension and positive screening test for PA,...

Introduction: Pheochromocytomas are catecholamine-producing tumors originated from the chromaffin cells of the adrenal medulla. Although usually sporadic, this tumors could be associated with germline mutations in about 40% of cases. TMEM127 has recently been identified as a novel gene conferring increased susceptibility to pheochromocytoma.Case report: A 42-year-old woman was referred to our Hospital to perform a right adrenalectomy for pheochromocytoma...

Introduction: Performance-enhancing drug (PED) use is currently a common practice both inside and outside the sports competition scenario, and its adverse health effects remain underappreciated.Case report: We report the case of a 26-year-old man, bodybuilding practitioner, no relevant medical history, family history of autoimmune disorders. Referred to the emergency room with polydipsia, polyuria, blurred vision associated with a post-prandial capillary...

Introduction: A two-step approach is usually used to diagnose GDM. At 24–28 weeks of pregnancy, a 50 g 1-hour glucose or O’Sullivan test is performed. If it is positive (≥140 mg/dl), it is followed by a 100 g-3 hours-Oral Glucose Tolerance Test (OGTT) which is considered positive if at least two or more values are ≥ of reference values (105-190-165-145 mg/dl). Despite it is not include in any clinical practice guideline, sometimes the 100 g OGTT is obviat...

Methods: Retrospective and descriptive study in a sample of 36 patients with suspected hypoglycemia who were admitted to our Service to perform a 72-hour fasting test. Demographic, clinical data and results of fasting test were analyzed. Endogenous hyperinsulinism criteria were considered to be the combination of plasma glucose <55 mg dl, insulin >3 mcrU / ml and C peptide > 0.6 ng/ml, in the absence of detection of sulfonylureas.Results: The...

Introduction and aims: Autophagy is an essential process for cell homeostasis that implies recycling and degradation of damaged organelles and long-lived proteins. It is induced during caloric restriction (in order to obtain energy) or other stress-inducing conditions. Autophagy is initiated by autophagosome formation, a double-membrane vesicle which engulfs cellular components and delivers them for degradation by fusing with lysosomes. Thus, proper autophagy regulation favour...

Introduction: Somatostatin analogs (SS-analogs) are the treatment option when there is a persistent disease despite surgical intervention. They can be also recommended as a first line treatment if surgery is not appropriate (non-curative or contraindicated surgery).Objetive: To evaluate the effect of first-generation SS-analogs (lanreotide and octreotide) on tumour shrinkage and biochemical control in naive patients.Methods: We per...
