Improved glycemic control with once-weekly dulaglutide in addition to insulin therapy in type 2 diabetes mellitus patients on hemodialysis evaluated by continuous glucose monitoring

Aims

To evaluate the efficacy and safety of adding once-weekly dulaglutide to insulin therapy in type 2 diabetes mellitus (T2DM) patients on hemodialysis.

Methods

Fifteen insulin-treated T2DM patients on hemodialysis were enrolled. Continuous glucose monitoring was performed before (1st hospitalization) and after the fifth dulaglutide administration (2nd hospitalization). The insulin dose was reduced after the first administration of dulaglutide (1st hospitalization day 6). Parameters of glycemic control were compared on 1st hospitalization days 4–5, 2nd hospitalization days 3–4, and days 6–7.

Results

The median total daily insulin dose was reduced significantly from 12 (12–25) to 0 (0?12) U (p?P?=?0.006 and 8.2 to 6.9?mmol/L, P?=?0.053, respectively). %CV of glucose levels decreased significantly after dulaglutide administration (28.1 to 19.8, P?=?0.003 and 28.1 to 21.0, P?=?0.019). However, the incidence of hypoglycemia remained unchanged.

Conclusions

Dulaglutide may improve glycemic control and excursion and allow total daily insulin to be reduced without increasing the risk of hypoglycemia in T2DM patients on hemodialysis.
