简要总结
In noncritically hospitalized patients, hyperglycemia (defined as blood glucose [BG] levels >140 mg/dL) is a common, serious, and costly healthcare problem. On the other hand, the treatment of hyperglycemia is associated with decreased mortality and morbidity. Therefore, clinical guidelines from professional organizations recommend using subcutaneous insulin as the preferred therapy in hospitalized patients in a non-intensive care unit setting (target glucose range 100 - 180 mg/dl). The most recommended regimen is basal-bolus insulin therapy, although this regimen requires multiple daily insulin injections and is associated with a significant risk of hypoglycemia (reported in up to 32%). Thus, a more straightforward regimen that results in similar glycemic efficacy to basal-bolus insulin with less risk of hypoglycemia could improve care for this group of patients.
The basal-plus insulin regimen consists of a daily dose of basal insulin with supplemental (corrective) doses of rapid-acting insulin analogue before meals. This has similar efficacy and safety as the basal-bolus regimen. However, the basal-plus scheme does not provide prandial coverage of insulin.
In another vein, dipeptidyl peptidase-4 (DPP-4) inhibitors are a class of oral glucose-lowering agents that reduce the breakdown of endogenous glucagon-like peptide-1 (GLP-1), stimulating insulin secretion in a glucose-dependent manner. Some clinical trials have demonstrated that DPP-4 inhibitors, in combination with insulin, result in similar improvement in glycemic control and lower rates of hypoglycemia compared to basal-bolus insulin regimens.
For the above, using a long-acting insulin analogue with a DPP-4 inhibitor could provide better glycemic control basal and prandial, and this scheme could represent an alternative to using a basal-plus regimen alone.
In the present study, the investigators will conduct a prospective randomized clinical trial (RCT) to compare the DPP-4 inhibitor, sitagliptin, combined with basal-plus insulin therapy and basal-plus insulin scheme alone in non-critical hospitalized patients.
详细描述
Patients with a known history of diabetes will be randomized to receive sitagliptin plus basal (glargine) insulin or a basal-plus regimen with glargine. Both groups will receive correction doses of rapid-acting insulin lispro in the presence of hyperglycemia (BG >180 mg/dL) per sliding scale. The overall hypothesis is that treatment with sitagliptin in combination with basal insulin will result in better glycemic control and a lower frequency of hypoglycemic events than treatment with a basal-plus insulin regimen in patients with type 2 diabetes in the hospital setting.
68 subjects with type 2 diabetes will be recruited for this study.
