Objective: The major diagnostic problem in primary aldosteronism is the differentiation between bilateral hyperplasia and aldosterone producing adenoma which is essential for further treatment. Adrenal vein sampling is regarded as the current gold standard, however it is an invasive, highly examiner-dependent method. Molecular imaging targeting the aldosterone synthase (CYP11B2) which is expressed specifically in aldosterone producing adrenal tissue may be an useful alternativ...

In patients with primary aldosteronism (PA), adrenal vein sampling (AVS) is considered the gold standard to distinguish between unilateral and bilateral disease, while diagnostic imaging tests (CT/MRI) are often inconclusive for the diagnosis of PA. To date agreement is lacking on the best criteria indicating successful cannulation and lateralization. Aim of the study was to evaluate the impact of different diagnostic criteria for the successful cannulation and lateralization ...

Adrenocortical tumors (ACT) include benign and malignant tumors. Adrenocortical carcinomas (ACC) are highly malignant neoplasms with a poor prognosis, but their genetic alterations to date identified are limited. Laboratory studies on ACT have revealed a wide variety of signaling pathways involved in these tumors, among these Wnt/β-catenin signaling pathway and Ras/Raf/MEK/ERK pathway resulted often disregulated. Another important factor in many signaling pathways is the ...

Hypertygiceridemia is responsible from the 1–4% of acute pancreatitis cases. When serum triglyceride level rises above 1000–2000 mg/dl, risk of having acute pancreatitis also increases. Medical therapy is usually inadequate for treatment of hypertryglyceridemia cases which cause severe and recurrent pancreatitis attacks. In our case we have reported a patient having recurrent attacks under medical therapy and underwent plasmapheresis.Case: 45 y...

Introduction: Isolated IgA deficiency (SIgAD) is the most common form of primary immunodeficiency. Patients with SIgAD have an increased risk of both systemic and organ-specific autoimmune diseases. Autoimmune thyroid diseases (AITD) and type 1 diabetes mellitus (T1DM) are the most common autoimmune endocrine disorders. They occur frequently together, and this combination is nominated as autoimmune polyglandular syndrome type 3 (APS 3). Primary hyperparathyroidism (PHPT) is th...

Introduction: Measles virus infections generally occur in childhood, but infections in adolescence and adulthood can lead to complications.Case report: A previously well 28-year-old woman had suffered from nausea, vomiting and generalized fatique for one day before being transferred to our emergency department in a confused state. A diagnosis of type 1 diabetes mellitus (T1D) complicated by ketoacidosis was made based on markedly decreased serum C-peptid...

Background and aims: The distribution of arterial occlusive disease is not fully explained in diabetes. The aim of this study was to examine the prevalence of CHD and PAD in diabetic patients complicated by abnormal test of distal autonomic function (Neuropad®) and large fibre neuropathy.Materials and Methods: 237 patients were analysed, M/F 111/126, age (mean±SD) 61.3±9.5years (ys), diabetes duration 16.4±10.6ys., type 1 n=22 (9.3%),...

Neuroendocrine tumors are rare in young patients and usually have favorable course. We present a case of young, 13-year-old girl diagnosed with insulinoma. The diagnosis was stated on the basis of the presence of neuroglycopenic symptoms. An abdominal CT scan demonstrated a tumor localized in the head of pancreas. The patient received diazoxide as a preparation to surgery. Therapy was effective, but discontinued due to side effects. Patient underwent the Whipple operation. Dur...

Background: Ketoconazole is a synthetic antifungal drug, and powerful inhibitor of steroidogenesis. Oral ketoconazole blocks both ovarian and adrenal androgen biosynthesis, and glucocorticoid synthesis, leading to a reduction in circulating testosterone and cortisol levels. In subjects with an intact HPA axis, ketoconazole by decreasing cortisol levels leads to compensatory rise an ACTH level.Objectives: To assess influence ketoconasole induced changes i...

Introduction: GDF-15 and TGF-β1 are growth factors involved in immune modulation and development of arteriosclerosis. Aim of this study was to assess whether GDF-15 and TGF-β1 concentrations are higher in adipose vs non-adipose individuals and whether this indicates early immune modulation with higher risk of arteriosclerosis.Description of methods: We examined 84 healthy individuals: 38 non-obese (average age 24.9 years) with mean BMI of 20.5+...
