OBJECTIVE: Netazepide (YF476) is a recently developed, orally active gastrin receptor antagonist that, in short trials in patients with type 1 gastric enterochromaffin-like cell neuroendocrine tumours, has been shown to induce a significant reduction in the number and size of tumours as well as serum chromogranin A (CgA). The aim of this review is to evaluate the long-term effect and safety of netazepide. PATIENTS AND METHODS: Five patients previously treated with netazepide in an open-label trial were offered continuous treatment with netazepide 25 mg once daily...

Phaeochromocytoma is a tumor of the catecholamine-producing cells of the adrenal gland. Extraadrenal phaeochromocytomas are frequently called paragangliomas. The majority of phaeochromocytomas are sporadic, however, about 25-30% are caused by genetic mutation. These tumor are frequently referred as hereditary phaeochromocytomas/paragangliomas. Their incidence increases continuously which can be attributed to availability of genetic examination and to the discovery of novel genes. The 47-year-old female patient underwent abdominal computed tomography which revealed bilateral adrenal gland enlargement...

BACKGROUND: The stress reaction induced by surgery and associated pain may be detrimental for patient recovery and should be minimized. The neuropeptide chromogranin A (CGA) has shown promise as a sensitive biomarker for stress in humans. Little is known about CGA and its derived peptides, catestatin (CST) and vasostatin (VS), in dogs undergoing surgery. The objectives of this study were to investigate and compare concentrations of CGA epitopes CST and VS, cortisol, body temperature, heart rate, respiratory rate, scores of the short form of the Glasgow composite measure pain scale (CMPS-SF) and visual analog scales (VAS) for stress and pain behavior in dogs before and after ovariohysterectomy...

Neuroendocrine tumor (NET) of the appendix is the most common gastrointestinal epithelial tumor in children. The utility of serum markers or the indication for hemicolectomy has not been established in children. In 45 children diagnosed with appendiceal NET, 89% NETs were incidentally found following appendectomy performed for suspected acute appendicitis. The median age was 12 years, and 56% patients were female. Postoperative somatostatin scan (n=5), serum chromogranin A (n=4), and urine 5-HIAA (n=9) were all within normal limits...

BACKGROUND: Repeated freezing and thawing of plasma (or serum) may influence the stability of plasma (or serum) constituents. Despite the alarming warnings from commercial manuals that freeze-thaw cycles affect the stability of hormones in plasma (or serum), surprisingly little, consistent information about this concept is available in literature. METHODS: We studied the stability of 15 endocrine parameters (ACTH, osteocalcin, plasma renin activity, α-subunits, CBG, glucagon, inhibin B, fT4, TT4, TT3, rT3, TBG, TSH, chromogranin A and thyroglobulin upon repeated freeze-thaw cycles in plasma (or serum) samples from 10 volunteers...

OBJECTIVES: Autoimmune gastritis may be associated with other organ-specific autoimmune disorders, but the prevalence of this association is not entirely quantified. The aims of this study were to investigate the prevalence of autoimmune disorders and evaluate the factors that might affect this association in patients with autoimmune gastritis. METHODS: A total of 320 patients with autoimmune gastritis were retrospectively studied and data on concomitant autoimmune diseases, serum gastrin and chromogranin A levels, anti-Hp IgG, antiparietal cell antibodies, presence of enterochromaffin-like cell hyperplasia and gastric atrophy were gathered for each patient and associations between autoimmune gastritis and studied parameters were explored through descriptive statistics and logistic regression analysis...

Histologically confirmed small cell lung cancer associated with Cushing's syndrome and elevated amylase is rarely described in the literature. We present a case of a 63-year-old patient admitted to cardiology department due to shortness of breath, exhaustion, palpitations and nausea. Elevated values of troponin and electrocardiography suggested that he could have acute coronary syndrome. According to the radiologist's opinion, plane lung radiography was normal. Elevated level of amylase was found in both serum (3802 U/L, normal range 28-100) and urine (12012 U/L, normal range 0-450 U/L), as well as elevated sodium (156 mmol/L, normal range 137-147 mmol/L), hyperglycemia (12 mmol/L, normal range 3...

Autoimmune polyglandular syndrome by definition consists of two or more endocrinological insufficiencies or two organ specific autoimmune diseases. There are no stringent criteria for endocrinological evaluation of patients with one endocrine insufficiency. However, detailed endocrinological evaluation should be undertaken in patients with two autoimmune diseases. Additionally, follow up thereafter should be a must in these patients in order to avoid the possibility of not diagnosing subsequent autoimmune diseases that can occur...

INTRODUCTION: In patients with severe illness, such as aneurysmal subarachnoid hemorrhage (SAH), a physiologic stress response is triggered. This includes activation of the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system. The aim of this study was to investigate the very early responses of these systems. METHODS: A porcine animal model of aneurysmal SAH was used. In this model, blood is injected slowly to the basal cisterns above the anterior skull base until the cerebral perfusion pressure is 0 mm Hg...

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are highly vascularized neoplasms, capable of synthethisizing VEGF-A, a key mediator of angiogenesis. In pancreatic neuroendocrine tumors (pNETs) VEGF expression is higher in benign and low-grade tumors and associated with good prognosis (neuroendocrine paradox) while the VEGF role in gastrointestinal NETs (GI-NETs) is still unclear. In this study, we examined the VEGF-1154A/G polymorphism in 145 GEP-NET patients and 150 controls. Next, we measured VEGF serum levels and VEGF tumor protein expression, comparing it with Ki67 and tumor grade...

A 67-year-old man had a gastric polyp diagnosed on screening. Atrophic changes in the upper gastric mucosa were seen on upper gastrointestinal endoscopy. In addition, endoscopy revealed in the middle area of the stomach wall a 10 mm polyp that was diagnosed as a carcinoid tumor through biopsy. Blood serum gastrin was elevated at 2,800 pg/mL.We diagnosed a Rindi Type 1 gastric carcinoid. The patient was planned to be treated with surgical laparoscopy assisted distal gastrectomy (LADG); however, the procedure was changed to intraoperative laparoscopy assisted total gastrectomy (LATG)...

BACKGROUND: Abiraterone Acetate (AA) represents a highly effective androgen-receptor (AR) axis targeted agent. Treatment with AA in castration-resistant prostate cancer (CRPC) may partly mediate neuroendocrine differentiation (NED) as an escape mechanism, which may have implications for the choice of sequential therapy in CRPC. We evaluated how treatment with AA influences circulating neuromediators chromogranin A (CGA), neuron-specific enolase (NSE), and pro-gastrin-releasing peptide (Pro-GRP) in chemotherapy-naïve CRPC patients...
