Brief Summary

High blood glucose levels in hospitalized patients with diabetes are associated with increased risk of medical complications and death. Improved glucose control with insulin injections may improve clinical outcome and prevent some of the hospital complications. Glargine (Lantus®) insulin injection is the most common treatment of diabetes in the hospital. Sitagliptin (Januvia®)is effective in lowering blood glucose. In a recent pilot study aiming to determine differences in glycemic control between treatment with sitagliptin (Januvia®) alone or in combination with basal insulin and basal bolus regimen in general medicine and surgery patients with type 2 diabetes (T2D). The investigators found that treatment with sitagliptin alone or in combination with basal insulin resulted in similar glycemic control compared to basal bolus regimen.

The investigators will conduct a prospective RCT aimed to determine the safety and efficacy of sitagliptin therapy for in-hospital and post-discharge management of general medicine and surgical patients with T2D. A total of 280 patients with known history of diabetes will be randomized to receive sitagliptin plus basal (glargine) insulin once daily (group 1), or basal bolus regimen with glargine once daily and aspart or lispro insulin before meals (group 2). If needed, patients in the treatment groups will receive correction doses of rapid-acting insulin in the presence of hyperglycemia (BG > 140 mg/dl). The overall hypothesis is that treatment with sitagliptin in combination with basal insulin in patients with type 2 diabetes will result in a similar improvement in hospital and post-discharge glycemic control and in a lower frequency of hypoglycemic events than treatment with basal bolus insulin regimen with glargine once daily and lispro insulin before meals.

Patients will be recruited at Grady Memorial Hospital, Emory University Hospital, University of Michigan, Ohio State University and Temple University

Detailed Description

Specific Aim 1: To determine whether in-hospital glycemic control, as measured by mean daily blood glucose concentration and frequency of hypoglycemic events, is different between treatment with sitagliptin (Januvia®) in combination with basal insulin (glargine) and basal bolus regimen (glargine and rapid-acting insulin analog) in general medicine and surgery patients with T2D. Patients with T2D treated with diet and/or OAD or with low total daily dose insulin therapy (≤0.6 unit/kg/day) will be randomized to receive sitagliptin plus glargine insulin (group 1) or basal bolus regimen with glargine once daily and rapid-acting insulin (lispro or aspart) before meals (group 2). If needed, patients in the 2 treatment groups will receive supplemental (correction) doses of rapid-acting insulin before meals for BG > 140 mg/dl.

Specific Aim 2: To determine the efficacy and safety of an A1C based discharge algorithm in controlling BG after discharge in patients with T2D. Patients who participate in the in-hospital (Aim 1) arm will be invited to enroll in this open label prospective outpatient study. The total duration of the study is 6 months. Patients with HbA1c ≤ 7% will be discharged on the combination of metformin and sitagliptin (Janumet ®) twice daily. Those with HbA1c between 7% and 9% will be discharged on metformin and sitagliptin (Janumet ®) twice daily plus glargine insulin at 50% of the inpatient glargine dose. Those with HbA1c > 9% will be discharged on metformin and sitagliptin (Janumet ®) twice-daily plus glargine insulin at 80% of the inpatient dose.
