High dose and long-term glucocorticoid (GC) therapy reduce bone mass and negatively affect the metabolic profile. Patients in remission after successful treatment of Cushing’s syndrome (CS) often present hypoadrenalism and require long-term GC replacement.Objective: To evaluate the effect of GC therapy on bone and metabolic parameters in women after long-term remission of CS. Materials and methods: Thirty-two women (mean age: 50±14 years) with ...

Introduction: Type 1 diabetes mellitus (T1DM) is considered, in general, a disease of children and young adults with normal body mass index (BMI), linked to a genetic susceptibility based on autoimmunity. However, we know that it can be diagnosed at any age and we must differentiate it from type 2 diabetes mellitus.Objetives: To investigate the phenotypic characteristics and the presence of specific autoimmunity in T1DM patients diagnosed in our hospital...

Introduction: Graves’ orbitopathy (GO) is the most common extrathyroidal manifestation of Graves’ disease. The first-line treatment are intravenous corticoids in active moderate-severe GO. Tocilizumab is a humanized monoclonal antibody against the IL-6 receptor which has been approved for the treatment of rheumatoid arthritis and is in its research stage for patients with corticosteroid-refractory GO.Objectives: To assess the experience with to...

Introduction: Thyroid cancer is the most frequent malignant endocrine neoplasia. Its incidence has significantly risen worldwide in the last decades.Objective: To estimate the incidence of thyroid cancer in Valladolid’s east area population, Spain, over the period 2002–2016.Methods: A retrospective descriptive research was performed in the Clinical Universitary Hospital of Valladolid (HCUVa). Clinical data was obtained fr...

Behavior of thyroid function tests in a Brazilian elderly population using Big DataIntroduction: Interpretation of thyroid function data has changed over the last decades with several groups demonstrating changing in the thyroid axis with aging, particularly with a progressive increase in age-related TSH. With the proliferation of studies with large datasets, termed Big Data, sample sizes are no longer a challenge, and the possibility of using clinical l...

Correlation of three thyroglobulin assays in the management of differentiated thyroid cancer (DTC) patientsIntroduction: Thyroglobulin(Tg) is the main biochemical marker of DTC. Usual immunometric assays(IMA) are prone to interference by autoantibodies which can lead to erroneous results. LC-MS/MS has been described as an assay that may provide accurate results, however the literature reported up to 40% of undetectable rates in patients with positive thy...

Hypophosphatasia (HPP) is an inherited skeletal disease characterized by defective bone mineralization due to a deficiency in tissue-nonspecific alkaline phosphatase (TNALP). Patients with the severe infantile form of HPP have a poor prognosis that often results in high mortality by one year. Asfotase alfa is an approved therapy for HPP, while requires chronic injections to maintain efficacy. To develop a one-time gene therapy for HPP, we examined the safety and efficacy of AA...

Introduction: Angiosarcomas account for < 1% of all sarcomas, and are highly agressive neoplasms whose clinical course is striking: local recurrence, metastasis, and a high mortality rate. Primary angiosarcoma of the adrenal gland was first described in 1988 by Kareti et al. and is very rare with, so far, only 51 reported cases. Case report: A 49-year-old male, without prior malignancy, presented with a 4.9x5.9 cm right adrenal nodule and a 2.4 cm le...

Introduction: The bidirectional relationship of risk between breast cancer (BC) and thyroid cancer (TC) has been debated. Estrogens are proposed as agents implicated in the risk of developing TC promoting thyroid tumorigenesis. Therapies that reduce the effect of estrogens on their receptors in cancer cells are widely used.Objective: To correlate the use of hormonal therapy in BC with the prevalence of TC.Material and Methods: We p...

Introduction: The endocrine complications of COVID-19 remain largely unknown. Cases of central diabetes insipidus (CDI) have been reported after COVID-19, with hypophysitis being the most likely cause. COVID-19 vaccines potential adverse effects may mimetize some of these complications. We present a case of a woman who developed CDI one week after the 2 nd dose of BNT162b2 mRNA COVID-19 vaccine.Case Report: Female patient, 37 years old, with rheumatoid a...
