Introduction: The results of publications investigating the relationship between low maternal serum 25-hydroxyvitamin D (25OHD) level and gestational diabetes mellitus (GDM) are controversial and none of these publications have investigated this relationship according to the severity of 25OHD deficiency. Therefore, this study was conducted to assess the relationship between low maternal serum 25OHD and GDM according to the severity of 25OHD deficiency.Me...

Introduction: PHPT is a common endocrine disease characterized by hypercalcemia and different degree of osteoporosis and nephrolithiasis. PHPT arises in the context of an inherited disease in 5% of cases. Multiple endocrine neoplasia type 1 (MEN1) is the commonest cause of inherited PHPT. The main therapeutic approach for PHPT is surgery, however many patients refuse or have contraindications for surgery while others, in particular those with MEN1 PHPT, have persistent/relapsi...

Rasmussen Anne Qvist , Jorgensen Niklas Rye , Tfelt-Hansen Jacob , Bevilacqua Maurizio , Schwarz Peter

The calcium receptor (CASR) serves as one of the main regulators of the calcium homeostasis. CASR is expressed in among other tissues parathyroid chief cells and kidney tubule cells. It has been hypothesized that CASR gene variations are responsible for low circulating calcium levels together with hypercalciuria and thereby increased risk of kidney stones. The CASR gene polymorphism A986S has been shown associated to elevated serum calcium levels in vivo<...

Primary hyperparathyroidism (PHPT) is defined by hypercalcemia and high PTH levels. In recent years a variant of PHPT has been described, namely normocalcemic PHPT (NPHPT), which is characterized by normal serum calcium and high PTH levels, in the absence of other causes of secondary hyperparathyroidism. The epidemiology of NPHPT is poorly understood. We performed a survey in the early fall in a small Southern Italian village, in which all adult residents (n=1811) wer...

Parathyroid hormone is involved in calcium homeostasis through interactions with vitamin D. Because intact and truncated forms of PTH vary in their biological activity, assays that can accurately quantify the ratio of intact hormone to its fragments are of increasing significance in the diagnosis of endocrine, renal and bone diseases. Vitamin D and its metabolites circulate tightly bound to vitamin D-binding protein (DBP). Because DBP concentrations are altered in pregnancy, l...

Structure and frequency of clinical manifestations of primary hyperparathyroidism

Brutskaya-Stempkovskaya Elena , Shepelkevich Alla , Bilodid Irina , Kliausova Ekaterina , Lobashova Veronika

Introduction: Primary hyperparathyroidism (PHPT) is a result of overproduction of parathyroid hormone with pathologically changed parathyroid glands (PTG) and calcium-phosphorus metabolism disorders. Until now, PHPT is often detected late (in countries where there is no screening for hypercalcemia), when there are irreversible complications it manifested.Materials and methods: One hundred and nine patients with PHPT (mean age: 52.2±8.7 year...

A case report: hypoparathyroidism, nephrocalcinosis, and replacement therapy

Boysan Serife Nur , Ozgen Zeren , Sahin Tuna

Introduction: There is a risk of hypercalcemia, nephrolithiasis, nephrocalsinosis, and renal failure in the treatment of hypoparathyroidism. We present a case who has an improvement of this complication after changing large doses of vitamin D to physiological doses of 1,25(OH)2D itself.Case report: A 50 years old man was admitted to hospital. He had idiopathic hypoparatyhroidism from the age of 24. He was using oral 1,25(OH)2D 0.25 ...

Postsurgical hypoparathyroidism with ‘normal’ PTH

Azevedo Teresa , Martins Teresa , Lemos Manuel , Cunha Nuno , Valido Frederico , Rodrigues Fernando

Introduction: Hypoparathyroidism is characterized by hypocalcemia and low or inappropriately normal levels of PTH. The most common cause of hypoparathyroidism is iatrogenic due to anterior neck surgery. In recent years it was documented that vitamin D insufficiency is widespread.Aim: To investigate the cause of hypocalcemia in thyroidectomized patients with PTH within the reference range.Methods: Retrospective review of clinical re...

Introduction: Vitamin D (Vit D) is known for its action on bone metabolism. But recently more ubiquitous actions have been discovered. Vit D deficit is now considered as a world health problem because of it frequency and its consequences. Vit D deficiency seems to be involved in diabetes mellitus, and in autoimmune, neoplastic and cardio-metabolic diseases. The aim of our study was to analyze the incidence of cardio-metabolic diseases in a group of patients with vitamin D defi...

We present the case of a 75-year-old woman with a 10-year history of nephrolithiasis, for which she endured several sessions of extracorporeal shockwave lithotripsy (ESWL). She was directed to the Endocrinology unit for further investigations, due to persistent albeit minor increased values of blood calcium (10.48 mg/dl, normal 8.410.2 mg/dl). Here, the clinical supposition of primary hyperparathyroidism was confirmed. The tests revealed a mild hypercalcemia with hypopho...

Primary hyperthyroidism (PHPT) is one of the diseases which are usually diagnosed in asymptomatic period nowadays. Even though considerable success was achieved, in some cases PHPT is not found out before complications were developed. A prospective study focuses on diagnostics and therapy of PHPT has been in progress at two tertiary centers of endocrinology in the Czech Republic since January 1st, 2007, with early diagnosis of PHPT being one of its aims. In a 6-year period, th...
