Sitagliptin: Is It Effective in Routine Clinical Practice?

[摘要] Aim. The present study was conducted to determine the glycaemic effects of sitagliptin in type 2 diabetes patients.Methods. Data was collected from patient medical records of a major teaching hospital in Malaysia, from 2009 to 2012. Glycated hemoglobin (HbA1c) values prior to and up to 12 months after the initiation of sitagliptin were analysed. The change inHbA1cvalues was accounted for based on a generalized linear model generated using the Generalized Estimating Equations (GEE) method.Results and Discussion. Of the 457 patients, 53.6% were elderly and 81.4% were overweight. The meanHbA1c(standard deviation) before initiation of sitagliptin was 8.5 (1.4)%. This dropped to 7.7 (1.4)%, 3 to 6 months after initiation of sitagliptin, with a mean difference of 0.8% (95% confidence interval (CI): 0.7–1.0; P<0.001). However, this value increased to 8.0 (1.7)% after 7 to 12 months on sitagliptin (P=0.002) with a mean difference from baseline of 0.6% (95% CI: 0.4–0.7;P < 0.001).Conclusion. In routine clinical practice, sitagliptin produces a significant reduction in meanHbA1c(0.8%) within the first 6 months of use which corresponds to efficacy data obtained in controlled clinical trials. However, this reduction was lesser, 7 to 12 month later.
