Determinants Of The Growth Hormone Nadir During Oral Glucose Tolerance Test In Adults.

08:00 EDT 1st May 2019 | BioPortfolio

Summary of "Determinants Of The Growth Hormone Nadir During Oral Glucose Tolerance Test In Adults."

Growth hormone (GH) nadir (GHnadir) during oral glucose tolerance test (OGTT) is an important tool in diagnosing acromegaly, but data evaluating the need to adjust cut-offs to biological variables utilizing todays assay methods are scarce. We therefore investigated large cohorts of healthy subjects of both sexes to define normal GHnadir concentrations for a modern, sensitive, 22kD-GH specific assay.

Is GH nadir during OGTT a reliable test for diagnosis of acromegaly in patients with abnormal glucose metabolism?

The growth hormone (GH) nadir during oral glucose tolerance test (OGTT) is the gold standard diagnostic test for acromegaly. The utility of OGTT-GH suppression test in patients with abnormal glucose m...

Growth hormone response to oral glucose load: from normal to pathological conditions.

The exact physiological basis of acute GH suppression by oral glucose is not fully understood. Glucose-mediated increase in hypothalamic somatostatin seems to be the most plausible explanation. Attemp...

Effect of portal glucose sensing on incretin hormone secretion in a canine model.

It is unknown whether activation of hepato-portal vein (PV) glucose sensors plays a role in incretin hormone amplification of oral glucose stimulated insulin secretion (GSIS). In previous studies PV g...

Diagnosis of disorders of glucose tolerance in women with polycystic ovary syndrome (PCOS) at a tertiary care center: fasting plasma glucose or oral glucose tolerance test?

The risk of developing prediabetes and type 2 diabetes (dysglycemia) may be increased in women with PCOS. Whether an oral glucose tolerance test (OGTT) should be performed routinely in all PCOS women ...

Difference in the prevalence of gestational diabetes mellitus according to gestational age at 75-g oral glucose tolerance test, in Japan: The JAGS trial.

To evaluate the differences in the results of 75-g oral glucose tolerance tests (OGTTs) according to gestational age, in Japan.

Growth Hormone Feedback to Insulin-like Growth Factor-I (IGF-1) and Oral Glucose Tolerance Test (OGTT)

Growth hormone (GH) and Insulin-like growth factor-I (IGF-I) secretion are altered in acromegaly and type 2 Diabetes Mellitis (DM). The secretion of GH is mediated by central hypothalamic...

Glucose Tolerance in Children With Cystic Fibrosis

The aim is to describe the association of glucose tolerance measured with three different tools (continuous glucose measurement system - CGMS, oral glucose tolerance testing - OGTT and opt...

Effects of Short-term Growth Hormone in HIV-infected Patients

The purpose of this study is to examine the short-term effects of two different doses of growth hormone on the brain's secretion of growth hormone and the body's glucose metabolism. We hy...

Glycemic Fluctuations in Newly Diagnosed Growth Hormone-Secreting Pituitary Adenoma and Cushing Syndrome Subjects

Glucose fluctuations present not only in patients with diabetes mellitus but also in subjects with normal glucose tolerance or impaired glucose regulation. People with Growth Hormone-Secre...

Effects on Insulin Sensitivity and Body Composition of Combination Therapy With Growth Hormone (GH) and Insulin-like Growth Factor-I (IGF-I)in Growth Hormone Deficient(GHD) and Diabetes and Impaired Glucose Tolerance(IGT)

The aim of this study is to measure effects of the combined treatment with GH and IGF-I on glucose sensitivity and body composition in patients with GHD and IGT or diabetes.

Medical and Biotech [MESH] Definitions

A test to determine the ability of an individual to maintain HOMEOSTASIS of BLOOD GLUCOSE. It includes measuring blood glucose levels in a fasting state, and at prescribed intervals before and after oral glucose intake (75 or 100 g) or intravenous infusion (0.5 g/kg).

A 191-amino acid polypeptide hormone secreted by the human adenohypophysis (PITUITARY GLAND, ANTERIOR), also known as GH or somatotropin. Synthetic growth hormone, termed somatropin, has replaced the natural form in therapeutic usage such as treatment of dwarfism in children with growth hormone deficiency.

A pituitary tumor that secretes GROWTH HORMONE. In humans, excess HUMAN GROWTH HORMONE leads to ACROMEGALY.

A pathological state in which BLOOD GLUCOSE level is less than approximately 140 mg/100 ml of PLASMA at fasting, and above approximately 200 mg/100 ml plasma at 30-, 60-, or 90-minute during a GLUCOSE TOLERANCE TEST. This condition is seen frequently in DIABETES MELLITUS, but also occurs with other diseases and MALNUTRITION.

An autosomal recessive disorder characterized by short stature, defective GROWTH HORMONE RECEPTOR, and failure to generate INSULIN-LIKE GROWTH FACTOR I by GROWTH HORMONE. Laron syndrome is not a form of primary pituitary dwarfism (GROWTH HORMONE DEFICIENCY DWARFISM) but the result of mutation of the human GHR gene on chromosome 5.
