Rationale: The Aldosterone:Renin ratio (ARR) is commonly used for patients fulfilling screening criteria for primary hyperaldosteronism (PA), followed by confirmatory testing. Reference intervals for interpretation of the ARR vary in accordance with local population and assay 1. While ARR provides high sensitivity for PA, this is compromised by low specificity, further compounded by medication interference. However, additional variables may improve the specificity of ARR as a ...

Objective Vitamin D (VD) plays a role in immune response. Recent data shows that low levels of VD could worsen COVID-19 outcomes. This study aimed to establish an association between VD levels among COVID-19 patients with clinical outcomes and inflammatory markers.Methods Prospective multicentric cohort study. Consecutively recruitment. Patients were grouped according admission status and level of VD [sufficient >30 ng/ml (VDS), insufficient 20–...

Introduction: Metastatic disease into the thyroid is a rare event, despite the gland’s rich vascular supply. Renal cell carcinoma (RCC) is an unusual neoplasm that not only has the potential to recur after a latent disease-free interval, but also has the potential to metastasize to rare sites like the thyroid. However, of the clinically significant secondary neoplasms of the thyroid, metastatic RCC is the culprit in most cases. Case report: We prese...

Introduction: Zinc transporter 8 (ZnT8) autoimmunity has been established as one of the markers for the diagnosis of type 1 diabetes (T1D) along with glutamate decarboxylase (GAD) and tyrosine phosphatase IA-2 (IA-2) antibodies. The aim of this study is to understand the status of pancreatic autoimmunity in the diagnosis of T1D, with special attention to the usefulness of ZnT8. In addition, as a second objective, we study the proposal to perform the assessment of pancreatic au...

Introduction: The best timing for PRRT (peptide receptor radionuclide therapy) in the case of pancreatic neuroendocrine tumors (panNETs) is still to define, as randomized prospective trials are lacking. Recent studies suggest that some systemic therapies can affect response to PRRT, favoring an earlier use of the latter.Objective: To determine the efficacy and toxicity of PRRT, comparing its results when used as a second line systemic therapy (a...

Background: Muscle weakness may persist in patients with Cushing’s syndrome (CS) long-term after resolution of hypercortisolism, but mechanisms determining this sustained impairment are not known. We hypothesized that alteration of muscle structure, due to fatty infiltration, is associated with muscle dysfunctions in these patients.Patients & methods: Twenty-six CS women [mean(±S.D.) age 49±12 years; mean(±S....

Introduction: Type 1 Gastric neuroendocrine tumors account for 70 to 80 percent of all gastric neuroendocrine tumors (G-NETs) and they are found more commonly in older adults, particularly women. They are associated with autoimmune metaplastic atrophic gastritis (AMAG) with or without pernicious anemia. Endoscopically, they are usually smaller than 1 cm and often multiple. These tumors usually present a non-aggressive evolution. Our goal is to approach the presence of risk fac...

Introduction: Type 1 Gastric neuroendocrine tumors account for 70 to 80 percent of all gastric neuroendocrine tumors (G-NETs) and they are found more commonly in older adults, particularly women. They are associated with autoimmune metaplastic atrophic gastritis (AMAG) with or without pernicious anemia. They are usually smaller than 1 cm and often multiple. Our goal is to describe different characteristics of type 1 G-NETs and to study possible prognostic factors related to th...

Introduction: While iatrogenic Cushing’s syndrome is common, acquired isolated ACTH deficiency is a rare condition. Hypophysitis is the most common cause, and while most recently published cases are associated with immunotherapy, it may also be idiopathic. Hereby we present a case of cortical adrenal atrophy secondary to idiopathic acquired ACTH deficiency, in order to raise awareness about this condition.Material and Methods: Review of the patient&...

Aim: Comparing the effect of Faster Aspart insulin (Fiasp®) with previous insulin analogues (aspart, lispro) in type I diabetic patients with sensor-augmented pump therapy.Methods: Patients with Minimed Paradigm® insulin pumps, Enlite® sensors and Guardian® software (able to automatically stop the pump infusion to prevent hypoglycemia) were switched from previous insulin to Faster Aspart.
