Post-Transplant Glucocorticoid Induced Diabetes | Insulin Therapy for Post-transplant Glucocorticoid Induced Hyperglycemia

Post-Transplant Glucocorticoid Induced Diabetes research study

What is the primary objective of this study?

No consensus guidelines exist for management of post-transplant glucocorticoid induced hyperglycemia, but most published reviews recommend insulin as first line therapy. A variety of insulin regimens have been proposed, including mealtime short-acting regular or analog insulin, once daily neutral protamine hagedorn (NPH) insulin, pre-mixed insulin, or basal insulin alone such as glargine or detemir. However, no randomized trial has ever examined different insulin regimens to determine which most effectively controls post-transplant steroid-induced hyperglycemia. Consequently, the proposed study intends to examine three commonly used insulin regimens used for managing post-transplant once-daily glucocorticoid-induced hyperglycemia to determine which is most effective: - Group 1: Intermediate-acting (NPH) insulin at breakfast - Group 2: Short-acting insulin (regular or aspart) before meals - Group 3: Insulin glargine at breakfast Question/Hypothesis: Among three commonly used insulin regimens, which is most effective for managing post-transplant once-daily glucocorticoid-induced hyperglycemia?

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

Regular or Aspart insulinDrug: Regular human insulin or Insulin Aspart Other Names: Humulin R, Novolin R, Novolog, NovoRapid Route: Subcutaneous; Dosage: No fixed dose, varies between subjects; Frequency: daily before meals; Duration: 2 hours (Aspart) or 6 hours (Regular); for duration subjects are concurrently administered once-daily glucocorticoid.

Insulin glargineDrug: Insulin glargine Other Names: Lantus Route: Subcutaneous; Dosage: No fixed dose, varies between subjects; Frequency: daily before breakfast; Duration: 24 hours; for duration subjects are concurrently administered once-daily glucocorticoid.
