Type 2 diabetes carries a risk for hypoglycemia, particularly in patients on an intensive glucose control plan as a glucose-lowering strategy, where hypoglycemia may be a limitation for the therapy and also a factor underlying clinical inertia. Glucose-lowering medications that increase circulating insulin in a glucose-independent manner, such as insulin and sulfonylurea therapy, are the most c...

Hypoglycemia-associated autonomic failure (HAAF) occurs commonly in patients with longstanding diabetes, placing affected patients at increased risk for severe hypoglycemia. Previous studies have suggested that hypoglycemia-induced hypercortisolemia may be responsible for blunting subsequent sympathoadrenal responses to hypoglycemia; however, this view remains highly controversial. In this work...

To evaluate the roles of iatrogenic hypoglycemia and diabetes per se in the pathogenesis of defective hormonal counterregulation against hypoglycemia in insulin-dependent diabetes mellitus (IDDM), nondiabetic, and spontaneously diabetic BB/Wor rats were studied using a euglycemic/hypoglycemic clamp. In nondiabetic rats, recurrent (4 wk) insulin-induced hypoglycemia (mean daily glucose, MDG, 59 ...

Diminished responsiveness to hypoglycemia contributes to defective counterregulation in diabetes. Pancreatic and/or circulating somatostatin are elevated in diabetes, which may inhibit counterregulatory hormone release during hypoglycemia. Thus, a selective somatostatin receptor type 2 antagonist (SSTR2a) should improve hormone counterregulation to hypoglycemia. Nondiabetic (N) and streptozotoc...

Hypoglycemia in a neonate is defined as blood sugar value below 40 mg/dL. It is commonly associated with a variety of neonatal conditions like prematurity, intrauterine growth restriction and maternal diabetes. Screening for hypoglycemia in high-risk situations is recommended. Supervised breast-feeding may be an initial treatment option in asymptomatic hypoglycemia. However, symptomatic hypogly...

Acute hypoglycemia in children is not an uncommon disease that can be encountered in the Emergency Department. Most cases of childhood hypoglycemia are caused by ketotic hypoglycemia due to missed meals. Often, hypoketotic hypoglycemia can also occur, which suggests hyperinsulinemia or a defect in fatty acid oxidation. Carnitine is essential for long chain fatty acids transfer into mitochondria...

A patient with acute lymphoblastic leukemia repeatedly developed hypoglycemia during chemotherapy. Comparison of serum glucose trends between chemotherapy with and without L-asparaginase (L-Asp) demonstrated a strong association between L-Asp and hypoglycemia. Critical blood sampling during hypoglycemia indicated hyperinsulinism, suggesting that L-Asp induced hypoglycemia in the patient through...

Idiopathic Ketotic Hypoglycemia is the most common non-iatrogenic cause of hypoglycemia in children beyond infancy. It improves with age and is rare after puberty. Early morning hypoglycemia, responding promptly to glucose, is a typical presentation. Etiology of hypoglycemia is unclear; deficiency of gluconeogenic substrate (hypoalaninemia) has been widely proposed. Idiopathic Ketotic Hypoglyce...

Hypoglycemia is a condition of reduced blood glucose level below 70 mg/dl (3.9 mmol/l). Hypoglycemic coma is a medical emergency which usually associated with glycemia around 20 mg/dl (1.1 mmol/l). Prolonged severe hypoglycemia may result in permanent neurological disorders. Hypoglycemia also has a negative impact on the cardiovascular system. Severe hypoglycemia may induce ventricular arrhythm...

background: parenteral nutrition (pn) is a valuable life saving intervention, which can improve the nutritional status of hospitalized malnourished patients. pn is associated with complications including hyperglycemia. this study was conducted to compare two methods of blood glucose control in traumatic brain injury patients on pn. materials and methods: a randomized, open-label, controlled tri...
