In hypoparathyroidism, inadequate levels of parathyroid hormone (PTH) result in hypocalcemia and often hyperphosphatemia. Large doses of calcium (Ca) and active vitamin D are typically used to manage symptoms, although these are often associated with complications and do not address the underlying PTH deficiency. In the phase III REPLACE trial, 24 weeks of treatment with rhPTH(1–84) was associated with maintained serum Ca without urine Ca excretion increases despite clini...

Objective: According to recent studies, impaired secretion of GH is a frequent finding after ischaemic stroke. The aim of our study was to compare various available GH stimulation tests in post-stroke patients.Design: Seventeen patients were included in the study (12 males; mean age: 60.5 years; mean BMI, 27.7 kg/m2) with a mean 19.6 (±7.3) months after stroke. For screening, glucagon and small dose (0.15 μg/kg) GHRH-arginine (sdGHRH...

Introduction: Beside remnant ablation and treatment of known metastases, radioiodine treatment of differentiated thyroid cancer is suitable for the discovery of unknown or suspected metastatic disease. In this study, the clinical utility of SPECT/CT, a hybrid imaging method was evaluated after radioiodine therapy.Patients and methods: Between July 2007 and March 2012, 260 investigations were performed at 188 patients. Male:female ratio was 47:141. Every ...

The optimal treatment of hyperthyroidism in Graves’ disease is still an unresolved question. Hyperthyroidism recurs in 50% of patients after discontinuation of antithyroid therapy. In this retrospective study, Graves’ patients investigated in the endocrine unit of Pecs University between December 2004 and October 2006 were enrolled (68 women, 22 men, age 47 (15–79) years). Antithyroid drug therapy was applied for a minimum of one year and the treatment was withd...

Introduction: The autoimmune polyglandular syndrome is a complex, heterogeneous disease in which autoimmune diseases of endocrine and non-endocrine organs can occur. There are 4 subgroups: the early-onset APS I develops due to the mutation of the gene AIRE and characterized by the presence of Addison’s disease (AD), mucocutan candidiasis and hypoparathyroidism; the APS II is defined by the appearance of AD and autoimmune thyroid diseases (AITDs) and/or diabetes mellitus; ...

Introduction: Both cortisol and vasopressin are stress hormones. Earlier, our group demonstrated that serum concentrations of free cortisol at admissions to the Intensive Care Unit (ICU) were independent predictors of survival in critically ill patients. Other investigators have demonstrated that serum copeptin, a surrogate marker of vasopressin may also be a predictive factor in this patient population. The aim of our present study was to compare the prognostic roles of serum...

Introduction: The autoimmune polyglandular syndrome (APS) is a complex, heterogeneous condition in which autoimmune diseases (AIs) of endocrine and non-endocrine organs can occur. There are four subgroups. The majority of patients are categorized as having APS II or APS III. In APS II, patients have Addison’s disease (AD) and autoimmune thyroid diseases (AITDs) or type I. diabetes mellitus (T1DM), while in the APS III, AITDs are combined with other autoimmune illnesses ex...

Papillary thyroid cancer (PTC) cells and immune cells can kill each other by death ligands. Death ligands induce apoptosis only in sensitive cells. The sensitivity to apoptosis is regulated in a complex and poorly understood manner. The aim of this study was to investigate the Fas ligand (FasL) and Tumor Necrosis Factor-Related Apoptosis Inducing Ligand (TRAIL) expression in PTC cells and tumor infiltrating immune cells. Twenty-six PTCs without and fifteen PTCs with cervical l...

Traumatic brain injury (TBI) often results in long-term pituitary insufficiency. Regular endocrine screening of TBI patients is advised after the acute phase of the treatment period. We monitored pituitary functions in 32 TBI patients (28 men, 4 women). Endocrine tests were performed from 3 to 36 months after the brain injury. Thyroid functions, cortisol and ACTH levels, prolactin, sex hormone concentrations, GH/IGF1 axis and posterior pituitary function were evaluated. Additi...

Introduction: Significant hyponatremia may evolve in hypothyroidism, when however, elevated ADH levels have not been consistently demonstrated. On the other hand, it was shown that thyroid hormone substitution suppresses ADH, and its surrogate marker copeptin secretion. The aim of our present study was to investigate the possible humoral changes in a special model of resolution of short term severe hypothyroidism in differentiated thyroid cancer (DTC) patients.<p class="ab...
