NCT ID: NCT03406312 Recruiting - Clinical trials for Post Prandial Hypoglycemia

Validation of a Diagnostic Tool for Postprandial Hypoglycaemia in Patients After Roux en Y Gastric Bypass Surgery

Start date: June 1, 2017
Phase: N/A
Study type: Observational

Roux-en-Y gastric bypass (RYGB) leads to weight reduction but has also some unwanted side effects. A part of this population will develop postprandial reactive hypoglycemia (PPRH). At this moment no validated diagnostic tool exists for PPRH. The aim of this study is to prove an association between the Sigstad´s Score and the lowest postprandial glucose level in patients after RYGB surgery. This is investigated using a liquid mixed meal tolerance test (LMMTT). As a secondary hypothesis, associations between Edinburgh Hypoglycemia Scale (EHS) and postprandial glucose levels are investigated. Furthermore, changes of insulin and GLP-1 levels during the test are analysed. Patient characteristics including co-morbidities are studied as possible influencing parameters. Moreover, a healthy control group is included to validate the results. Finally, a flowchart/diagnostic method will be proposed for diagnosing patients who had a RYBG surgery with symptoms suggestive of PPRH. Besides the LMMTT, participants at the Ghent University Hospital will undergo additional tests such as a solid mixed meal tolerance test (SMMTT) and continuous glucose monitoring (CGM). Associations between Sigstad Score, EHS and the lowest glucose measured during CGM and SMMTT will be investigated and compared to the results of the LMMTT.

NCT ID: NCT03234491 Recruiting - Clinical trials for Post-Prandial Hypoglycemia

Improving Post-Prandial Blood Glucose Control With Afrezza During Closed-Loop Therapy

Start date: November 1, 2017
Phase: Phase 1
Study type: Interventional

The study will be conducted in two phases; an in-patient meal study phase (Phase I) and an outpatient home study (Phase II). The two phase study design is chosen to enhance safety by testing the Afrezza Closed-Loop (CL) system in controlled in-clinic setting under study staff supervision before it could be investigated at the outpatient home setting. Phase II will not begin without the establishment of safety in Phase I.
