About
With this study, the investigators hoped to learn if the rate at which food empties from the stomach affects blood sugar values. Using data from this study, we hope to improve our ability to control blood sugars in individuals with type 1 diabetes mellitus.
Full description
The study comprised 3 outpatient visits over a period of 11 days. Safety lab test were performed at the screening visit. At each visit, GE was evaluated by 13C-spirulina breath tests.
Phase 1:
After the baseline assessment (GE1), the second and third GE tests were performed during treatment with intravenous (GE2) and oral erythromycin (GE3) or placebo. Subject arrived fasting at each study visit. Prior to gastric emptying study, there was placement of an intravenous line. Subject continued to take insulin and other medications as usual. Subjects were required to do finger-stick glucose readings 4 times a day or as instructed by their physician. Subjects were provided with a log sheet to keep track of meal times, insulin dosing and times, glucose readings, and activities. Continuous glucose monitoring (CGM) and gastric emptying were evaluated for the duration of the study (11 days) and thrice respectively. GE was evaluated at baseline (GE1) and after randomized to intravenous saline, erythromycin (2 mg/kg) or erythromycin (3 mg/kg).
Phase 2:
Thereafter, patients were randomized to erythromycin ethyl succinate suspension (250 mg tid) or placebo for a total period of 7 days. GE3 was preferably performed on day 7, after oral erythromycin or placebo was started.
An EKG was performed at baseline to identify (and exclude) patients who have contraindications to erythromycin. An EKG was also repeated at the end of the study, i.e., on GE3 for safety. No change to insulin (apart from those that patients do with their self management skills) or other medications was made during this research study.
