Mechanistic reasons for this need to be understood better to develop appropriate therapies. To investigate delayed gastric emptying effects on postprandial glucose turnover, insulin sensitivity, and \u03b2-cell responsivity and function, as a feasibility study prior to studying patients with type 1 diabetes, we used the triple tracer technique C-peptide and oral minimal model approach in healthy subjects. A single dose of 30 \u03bcg of pramlintide administered at the start of a mixed meal was used to delay gastric emptying rates. With delayed gastric emptying rates, peak rate of meal glucose appearance was delayed, and rate of endogenous glucose production (EGP) was lower. C-peptide and oral minimal models enabled the assessments of \u03b2-cell function, insulin sensitivity, and \u03b2-cell responsivity simultaneously. Delayed gastric emptying induced by pramlintide improved total insulin sensitivity and decreased total \u03b2-cell responsivity. However, \u03b2-cell function as measured by total disposition index did not change. The improved whole body insulin sensitivity coupled with lower rate of appearance of EGP with delayed gastric emptying provides experimental proof of the importance of evaluating pramlintide in artificial endocrine pancreas approaches to reduce postprandial blood glucose variability in patients with type 1 diabetes. <\/jats:p>","DOI":"10.1152\/ajpendo.00199.2014","type":"journal-article","created":{"date-parts":[[2014,7,30]],"date-time":"2014-07-30T05:29:45Z","timestamp":1406698185000},"page":"E494-E502","source":"Crossref","is-referenced-by-count":35,"title":["Effects of delayed gastric emptying on postprandial glucose kinetics, insulin sensitivity, and \u03b2-cell function"],"prefix":"10.1152","volume":"307","author":[{"given":"Ling","family":"Hinshaw","sequence":"first","affiliation":[{"name":"Division of Endocrinology and Metabolism, Mayo Clinic, Rochester, Minnesota;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michele","family":"Schiavon","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, University of Padua, Padua, Italy;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashwini","family":"Mallad","sequence":"additional","affiliation":[{"name":"Division of Endocrinology and Metabolism, Mayo Clinic, Rochester, Minnesota;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiara Dalla","family":"Man","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, University of Padua, Padua, Italy;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rita","family":"Basu","sequence":"additional","affiliation":[{"name":"Division of Endocrinology and Metabolism, Mayo Clinic, Rochester, Minnesota;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adil.
