Strict glycaemic control has been associated with an increased mortality rate in subjects with type 2 diabetes (T2DM). Here we examined platelet function immediately and 24 hours following induced hypoglycaemia in people with type 2 diabetes compared to healthy age-matched controls.

Hyperinsulinaemic clamps reduced blood glucose to 2.8 mmol/L (50 mg/dl) for 1 hour. Sampling at baseline; euglycaemia 5mmol/L (90 mg/dl); hypoglycaemia; and at 24 post clamp were undertaken. Platelet function was measured by whole blood flow cytometry.

10 subjects with T2DM and 8 controls were recruited. Platelets from people with T2DM showed reduced sensitivity to prostacyclin (PGI2, 1 nM) following hypoglycaemia. The ability of PGI2 to inhibit platelet activation was significantly impaired at 24 hours compared to baseline in the T2DM group. Here, inhibition of fibrinogen binding was 29.5% (10.3 – 43.8) compared to 50.8% (36.8 – 61.1), (P < 0.05), while inhibition of P-selectin expression was 32% (16.1 – 47.6) vs. 54.4% (42.5 – 67.5) (P < 0.05). No significant changes in platelet function were noted in controls.

Induced hypoglycaemia in T2DM enhances platelet hyperactivity through impaired sensitivity to prostacyclin at 24 hours.
