Plasma glicentin in diabetic and gastrectomized patients

Add time:08/15/2019    Source:sciencedirect.com

Recent successful synthesis of human glicentin prompted us to establish an immunoassay method for determination of human glicentin in plasma. Human glicentin in plasma was measured using a newly developed sandwich ELISA. The mean fasting levels of human glicentin were 18.6±2.4 and 19.7±2.1 pM in normal subjects and diabetic patients, respectively. In diabetic patients with renal failure, plasma glicentin was elevated, exceeding 100 pM. In normal subjects, plasma glicentin increased to a peak level of about 130 pM at 60 min after an oral glucose load, and then decreased. In patients who underwent gastrectomy, plasma glicentin rapidly increased to a peak of about 300 pM at 30 min after oral glucose load. In a patient with short bowel syndrome plasma glicentin did not change following an oral glucose load. These results correspond with previous findings for gut glucagon-like immunoreactive materials (GLI) or enteroglucagon. We conclude that glicentin is secreted from the small intestine in response to intraluminal glucose stimulation in humans.
