Introduction: The main indications for the somatostatin analogues (SST-A) are acromegalies and/or neuroendocrine tumors. They can increase fecal fats, which could lead to the loss of fat soluble vitamins. There are few published studies showing the effects of the long-term use.Methods: Retrospective study of patients with SST-A indicated from our endocrinology department in the last 10 years. We analysed indications and different epidemiological, clinica...

Introduction: Vasoactive intestinal peptide-producing tumours (VIPomas) represent a rare type of neuroendocrine tumour whose incidence is 1 in 10 million per year. Most are located in the pancreas. They cause diffuse watery (secretory) diarrhoea, hypokalaemia and achlorhydria and also appear as an uncommon cause of hypercalcaemia.Case report A 69-year-old female with previous diagnosis of a ‘non-functioning’ neuroendocrine pancreatic tumour (20...

Objectives: To evaluate the prevalence of blood pressure alterations by ABPM and its association with clinical factors in normotensive and normoalbuminuric patients with type 1 diabetes (TDM1).Methods: Cross-sectional study including normotensive and normoalbuminuric patients with TDM1. Altered ABPM was considered when: i) Mean systolic pressure (sBP) was ≥130 mmHg in the 24 h and daytime periods and ≥120 mmHg in the night-time period and/or ...

Objectives: To evaluate the validity as diagnostic test of isolated blood pressure measurement compared to 24 h ambulatory blood pressure monitoring (ABPM) in a group of clinically normotensive patients with type 1 diabetes (TDM1).Methods: Cross-sectional study including 85 normotensive and normoalbuminuric patients with TDM1. Media of two blood pressure measures by conventional technique and results of the 24 h blood pressure monitoring (SPACELABS 90217...

Objectives: To evaluate the prevalence of blood pressure alterations with ambulatory blood pressure monitoring (ABPM) and its association with proinflammatory cytokines (IL-6 and VEGFα) in normotensive and normoalbuminuric patients with type 1 diabetes (TDM1).Patients and methods: Cross-sectional study including normotensive and normoalbuminuric patients with TDM1. Altered ABPM was considered when: 1) Mean systolic pressure (sBP) was greater than 13...

Objective: To evaluate changes of ambulatory blood pressure monitoring (ABPM) parameters in normotensive and normoalbuminuric patients with type 1 diabetes (TDM1) after 7 years.Methods: A longitudinal study conducted in normotensive and normoalbuminuric patients with TDM1. ABPM (Spacelabs 90217) basal was performed. Altered ABPM was considered when: i) Mean systolic pressure (sBP) was ≥130 mmHg in the 24 h and daytime periods and ≥120 mmHg in...

Transforming growth factor beta (TGFβ), which plays a key role in cancer and fibrotic disorders, mediates its actions mainly through activation of Smad transcription factors, which bind to Smad Binding Elements (SBEs) in target genes. We have previously observed that the thyroid hormone T3 blocks transactivation of SBE-containing reporter plasmids by TGFβ, and represses transcription of endogenous TGFβ target genes. We have now analysed the thyroid ho...

Introduction: Overt hypothyroidism is associated with diastolic hypertension, but in subclinical hypothyroidism, data are inconclusive. HS tiroxina is a double-blind trial evaluating the effect of levothyroxine on blood pressure in patients with mild SH (TSH 5.0–9.9 mU/l and normal free T4) and moderate-to-high cardiovascular risk.Methods: We analized baseline data of the first 46 patients screened. Confirmatory thyroid function tests wer...

Introduction: Graves’ and Hashimoto’s diseases are considered two extremes of the same autoimmune thyroid disease. Spontaneous conversion from hypothyroidism to hyperthyroidism is uncommon. On the other hand, Graves’ disease typically improves during pregnancy and worsens after delivery. We describe a patient with an unusual course of thyroid disease during pregnancy.Case report: An 33-year-old woman, with a two-year history of hypothyroid...

Introduction: The introduction of immunotherapy with checkpoint inhibitors for oncologic diseases has improved the survival and quality of life of our patients; however, these therapies are frequently associated with autoimmune endocrine disease.Methods: Revision of the patient’s clinical record and the related literature.Results: Clinical Case : An 88-year old woman was referred to our Endocrinology Clinic because of a PET i...
