Blood glucose profiles in East Asian and Caucasian injection‐naive patients with type 2 diabetes inadequately controlled on oral medication: a pooled analysis

摘要

Abstract Aim The primary objective of this study was to compare blood glucose (BG) excursions between East Asian and Caucasian patients with type 2 diabetes mellitus (T2DM) who were injection‐naive, had inadequate glycemic control with oral antihyperglycemic medications, and who required initiation with injectable therapy. Methods This retrospective pooled analysis included individual patient data from completed clinical trials (Insulin lispro injection/dulaglutide development programs, first patient visit ≥1997). All included patients were?≥18?years, were East Asian or Caucasian, and had data for self‐monitored BG at baseline. The primary outcome, BG excursion at baseline (least‐squares mean, standard error), was compared between patient groups using an analysis of covariance with race as the fixed effect. Independent covariates included baseline body weight, baseline HbA1c, age, and duration of T2DM. Results Caucasian ( n ?=?6779) and East Asian ( n ?=?1638) patients from 21 trials were included. BG excursions were significantly higher for East Asian than Caucasian patients at breakfast (4.03 [0.075] vs 2.59 [0.045] mmol/L), lunch (3.37 [0.080] vs 1.43 [0.049] mmol/L), and dinner (3.16 [0.080] vs 1.74 [0.047] mmol/L) ( P ??0.001 adjusted analyses). Similar findings were observed for the unadjusted analyses. At each time point, postprandial BG was significantly higher for East Asian than Caucasian patients (with adjusted and unadjusted analyses). Conclusion These findings suggest that BG excursion and postprandial BG are higher among East Asian patients with T2DM than Caucasian patients. In addition, these findings may help clinicians select appropriate treatments for East Asian patients with T2DM who require injection therapy.
