We investigated glucose metabolism in patients who underwent pancreatoduodenectomy(PD), distal pancreatectomy (DP), and partial resection(PR). Fifteen patients(36%)were diabetic(HbA1c≥6.5%)before PD, 16(38%)were diabetic after PD, and 6(60%)were diabetic both before and after DP. The level of HbA1c was not significantly different preoperatively( PD: 7.5±2.7%, DP: 7.5±1.3%)vs postoperatively(PD: 6.7±1.1%, DP: 6.3±0.7%). These results suggest that pancreatic endocrine function was fairly preserved in patients who underwent pancreatic surgery...

The recent epidemics of metabolic diseases, obesity, type 2 diabetes(T2D), liver lipid disorders and metabolic syndrome have largely been attributed to genetic background and changes in diet, exercise and aging. However, there is now considerable evidence that other environmental factors may contribute to the rapid increase in the incidence of these metabolic diseases. This review will examine changes to the incidence of obesity, T2D and non-alcoholic fatty liver disease (NAFLD), the contribution of genetics to these disorders and describe the role of the endocrine system in these metabolic disorders...

BACKGROUND: Autoimmune polyglandular syndrome type 2 (APS-2), also known as Schmidt's syndrome, is an uncommon disorder characterized by the coexistence of Addison's disease with thyroid autoimmune disease and/or type 1 diabetes mellitus. Addison's disease as the obligatory component is potentially life-threatening. Unfortunately, the delayed diagnosis of Addison's disease is common owing to its rarity and the nonspecific clinical manifestation. METHODS: Here we reported a case of 38-year-old female patient who presented with 2 years' history of Hashimoto's thyroiditis and received levothyroxine replacement...

The ability to yield glucose-responsive pancreatic beta-cells from human pluripotent stem cells in vitro will facilitate the development of the cell replacement therapies for the treatment of Type 1 Diabetes. Here, through the sequential in vitro targeting of selected signaling pathways, we have developed an abbreviated five-stage protocol (25-30 days) to generate human Embryonic Stem Cell-Derived Beta-like Cells (ES-DBCs). We showed that Geltrex, as an extracellular matrix, could support the generation of ES-DBCs more efficiently than that of the previously described culture systems...

Treatment-resistant hypertension (TRH) is defined as the failure to achieve an office BP target of <140/90 mmHg (<130/80 mmHg in patients with chronic kidney disease (CKD) or diabetes) in patients with hypertension (HT), despite adherence to at least 3 antihypertensive medications at optimal tolerated doses, ideally including a diuretic (Calhoun et al., Circulation 2008). TRH identifies patients with hard-to-treat HT, who might benefit from specialist investigation and treatment. Although some studies put the prevalence of TRH as >10%, these levels may be inflated by white-coat hypertension and poor adherence...

Type 2 diabetes mellitus (T2DM) is a complex endocrine and metabolic disorder and is a major global public health problem with a rapidly increasing prevalence. Although a wide range of pharmacotherapy for glycemic control in T2DM is now available, management of T2DM remains complex and challenging. The kidneys contribute to glucose homeostasis primarily by the glucose reabsorption from the glomerular filtrate. The sodium-glucose co-transporter 2 (SGLT2) inhibitors, a new class of antidiabetes agents that inhibit glucose absorption from the kidney tubule independent of insulin, offer a unique opportunity to improve outcomes for patient with T2DM...

BACKGROUND: Persistent organic pollutants (POPs) are a group of diverse substances, including polychlorinated biphenyls (PCBs) and organochlorine pesticides that are resistant to biodegradation and ubiquitously present in our environment. Exposure to endocrine disrupting chemicals such as POPs has been linked to type 2 diabetes and metabolic disturbances in epidemiological and animal studies, but little is known about POPs exposure during pregnancy and the development of gestational diabetes mellitus (GDM)...

Adipose tissue is a key endocrine organ that governs systemic homeostasis. PPARγ is a master regulator of adipose tissue signaling that plays an essential role in insulin sensitivity, making it an important therapeutic target. The selective PPARγ agonist rosiglitazone (RSG) has been used to treat diabetes. However, adverse cardiovascular effects have seriously hindered its clinical application. Experimental models have revealed that PPARγ activation increases cardiac hypertrophy. RSG stimulates cardiac hypertrophy and oxidative stress in cardiomyocyte-specific PPARγ knockout mice, implying that RSG might stimulate cardiac hypertrophy independently of cardiomyocyte PPARγ...

Excess visceral adipose tissue is associated with increased risk of high blood pressure, lipid disorders, type 2 diabetes, and cardiovascular disease. Adipose tissue is an endocrine organ with multiple humoral and metabolic roles in regulating whole-body physiology. However, perivascular adipose tissue (PVAT) also plays a functional role in regulating the contractile state of the underlying smooth muscle cell layer. Work during the past decade has shown that this adipose-vascular coupling is achieved by production of numerous substances released from PVAT...

Regulatory peptides produced in islet and gut endocrine cells, including glucagon, GLP-1, GLP-2, and GIP exert actions with considerable metabolic importance and translational relevance. Although the clinical development of GLP-1 receptor (GLP-1R) agonists and dipeptidyl peptidase-4(DPP4) inhibitors has fostered research into how these hormones act on the normal and diseased heart, less is known about the actions of these peptides on blood vessels. Here we review the effects of these peptide hormones on normal blood vessels, and highlight their vascular actions in the setting of experimental and clinical vascular injury...

Insulin secretion is elaborately modulated in pancreatic ß cells within islets of three-dimensional (3D) structures. Using human pluripotent stem cells (hPSCs) to develop islet-like structures with insulin-producing ß cells for the treatment of diabetes is challenging. Here, we report that pancreatic islet-like clusters derived from hESCs are functionally capable of glucose-responsive insulin secretion as well as therapeutic effects. Pancreatic hormone-expressing endocrine cells (ECs) were differentiated from hESCs using a step-wise protocol...

The islets of Langerhans are endocrine tissue clusters that secrete hormones that regulate the body's glucose, carbohydrate and fat metabolism, the most important of which is insulin, a hormone secreted by β cells within the islets. In certain instances, a person's own immune system attacks and destroys them leading to the development of Type 1 diabetes (T1D), a lifelong condition that needs daily insulin administration to maintain health and prolong survival. Islet transplantation is a surgical procedure that has demonstrated the ability to normalize blood sugar levels for up to a few years, but the need for chronic immunosuppression relegates it to a last resort that is often only used sparingly, and in seriously-ill patients...

Transplantation of islet allografts into type 1 diabetic recipients usually requires multiple pancreas donors to achieve insulin independence. This adds to the challenges of immunological monitoring of islet transplantation currently relying on surrogate immune markers in peripheral blood. We investigated donor origin and infiltration of islets transplanted in the liver of a T1D patient who died of hemorrhagic stroke four months after successful transplantation with two intraportal islet grafts combining six donors...
