Introduction: Vitamin D deficiency is very common in the population, including pregnant women. There are few studies in Spain to explain their causes, so we started one in the city of Burgos, Spain (latitude 42.2° N) in April 2009 to study vitamin D status, factors that can influence and their relationship with gestational diabetes. We present preliminary data from the study on vitamin D levels.Aims: Study in pregnancy: i) vitamin levels, and ii) it...

Anamnesis: We report the case of a 54-year-old man who consulted for weight loss. He had been diagnosed with diabetes more than 20 years ago with good glycemic control (currently HbA1c 6.9%), no obesity, hypertension, or dyslipidaemia. A history of chronic pancreatitis and retinitis pigmentosa with eyelid ptosis. He maintains regular treatment with metformin, sitagliptin, repaglinide, ASA, Kreon and Pregabalin.Complementary testIn reference to the chief complaint, there had no...

Introduction and objective: Treatment with integrated continuous subcutaneous insulin infusion (CSII) and continuous glucose monitoring systems (CGM) helps to improve glycaemic control in people with type 1 diabetes mellitus (DM1). There is increasing use in pregnant women, but there are no protocols for its continuation during delivery. The aim of this work is to analyse glycaemic control during pregnancy, in addition to studying obstetric and neonatal outcomes.<p class="...

Objective: Analysis of referrals from Primary Care to the Endocrinology Department for analytical findings of elevated prolactin levels and their subsequent management after initial assessment.Material and methods: Retrospective descriptive study of 118 patients who were referred to the Endocrinology and Nutrition department of the Dos Hermanas Peripheral Specialities Centre between October 2020 and December 2022. Patients already diagnosed with hyperpro...

Objective: Evaluate the utility of analytical determination of parathyroid hormone assay in fine-needle aspirate as a diagnostic test for parathyroid adenoma in patients with primary hyperparathyroidism.Material and Methods: retrospective observational study of 58 patients diagnosed with primary hyperparathyroidism in our hospital who underwent ultrasound-guided FNA of lesions compatible with parathyroid adenoma with determination of PTH in fine-needle a...

Objective: To investigate vitamin D status in patients with autoimmune hypothyroidism.Methods: The study group consisted of 100 patients with newly diagnosed Hashimato’s thyroiditis and 100 subjects as the control group. Parameters of calcium metabolism, thyroid function tests and 25(OH) vitamin D levels were measured.Results or case presentation: Mean age of the study groups was 33.4±4.8 years with female:male, 72:28. Vi...

Vitamin D is commonly used in the treatment of hypoparathyroidism after thyroid surgery. It is well recognised that excess vitamin D therapy leads to hypercalcaemia, and that this effect may be prolonged, lasting upto several weeks with some vitamin D preparations. We describe a case of severe, life threatening hypercalcaemia from vitamin D therapy, in which the duration of action of vitamin D was exceptionally long. A 51 year old lady presented with acute, severe haemorrhagic...

Background: Vitamin D deficiency is very common in older persons. It is not clear how serum 25-hydroxyvitamin D (25(OH)D) levels change during aging.Objective: To examine longitudinal changes in serum 25(OH)D levels in two representative cohorts of Dutch older persons during 6 and 13 years of follow-up, respectively.Methods: Data of the Longitudinal Aging Study Amsterdam (LASA) were used, an ongoing cohort study in older persons. T...

Vitamin D is essential to the control of calcium homeostasis and is mainly provided by exposure to sunlight. In the UK circulating Vitamin D is subject to seasonal variation with peak values occurring in early Autumn and trough values in late Spring. Requests for Vitamin D assays are increasing but few laboratories quote seasonal reference ranges and many commercial suppliers quote reference ranges for populations living in warmer, sunnier climates. This study established seas...
