---|---|
Experimental: Sitagliptin
Subjects undergoing cardiac surgery with type 2 diabetes (T2D) will be randomized to receive one tablet of sitagliptin once a day.Subjects with stress hyperglycemia (defined as a blood glucose (BG) greater than 180 mg/dL) in the intensive care unit (ICU) will continue to receive sitagliptin and will be started on continuous intravenous insulin (Regular Human Insulin) adjusted to achieve and maintain a BG target between 110 - 180 mg/dL following standard hospital protocol. Additionally, once moved to the regular floors and out of ICU, the subjects can receive insulin glargine, insulin lispro, and/or insulin aspart depending on the blood glucose level. Interventions: Drug: Sitagliptin Drug: Regular Human Insulin Drug: Insulin glargine Drug: Supplemental insulin (Insulin lispro) Drug: Supplemental insulin (Insulin aspart) |
Subjects will take one pill daily starting one day prior to surgery until discharge from the hospital.
Sitagliptin will be dispensed orally at 100 mg/day for patients with a glomeruler filtration rate (GFR) greater than or equal to 50.
Patients with a GFR between 30-49 will receive 50 mg/day.
Other Names:
Continuous intravenous insulin given to intensive care unit (ICU) patients with a blood glucose (BG) greater than 180 mg/DL and will be started on Regular Human Insulin adjusted to achieve and maintain a BG target between 110 - 180 mg/dL following standard hospital protocol.Intravenous insulin infusion will be continued until the patient is able to eat and/or is transferred to non-ICU service.
In previous studies, average length of insulin infusion in patients with stress hyperglycemia was 16.9±19 hours and the amount of IV insulin requirement was 18.6±24.3
U/day.
Other Names:
Patients that required continuous insulin infusion (CII) at a rate >1U/h will be transitioned to basal insulin (glargine/detemir). Calculate total daily dose (TDD) of insulin from the average CII rate during the last four hours of infusion (example, if the average rate is 2 U/hr., the TDD is 48 U/day) Give 50% of calculated dose as basal (glargine/detemir) insulin every day. Basal insulin will be given approx. 4 hours before discontinuation of CII. The total daily insulin dose will be adjusted as follow: Fasting and pre-meal BG between 100-180 mg/dl without hypoglycemia the previous day: no change Fasting and pre-meal BG between >180-240 mg/dl: increase basal dose by 10% every day Fasting and pre-meal BG >241 mg/dl: increase basal dose by 20% every day Fasting and pre-meal BG <100 mg/dl: stop basal
Other Names:
Insulin lispro will be administered before meals in addition to scheduled insulin dose following the supplemental insulin scale protocol. At bedtime, half of supplemental sliding scale insulin starting at blood glucose (BG) greater than 240 mg/dL will be given. For the subjects receiving supplemental insulin lispro with BG levels greater than 180 mg/dL, then supplemental insulin scale is as follows:
Other Names:
Insulin aspart will be administered before meals in addition to scheduled insulin dose following the supplemental insulin scale protocol. At bedtime, half of supplemental sliding scale insulin starting at blood glucose (BG) greater than 240 mg/dL will be given. For the subjects receiving supplemental insulin aspart with BG levels greater than 180 mg/dL, then supplemental insulin scale is as follows:

Placebo Comparator: Placebo
Subjects undergoing cardiac surgery with type 2 diabetes will be randomized to receive one tablet of placebo once a day.Subjects with stress hyperglycemia (defined as a blood glucose (BG) greater than 180 mg/dL) in the intensive care unit (ICU) will continue to receive a placebo and will be started on continuous intravenous insulin (Regular Human Insulin) adjusted to achieve and maintain a BG target between 110 - 180 mg/dL following standard hospital protocol. Additionally, once moved to the regular floors and out of ICU, the subjects can receive insulin glargine, insulin lispro, and/or insulin aspart depending on the blood glucose level.
