Glycemic variability and iatrogenic hypoglycemia: how to resolve

Diabetes Res Clin PractPublished Analysis of randomised controlled trials

Authors' conclusion

As such thresholds are the upper limit or the averaged value of %CV glucose, respectively, in non-diabetic people, the ultimate goal to prevent hypoglycemia in people with type 1 diabetes on intensive insulin therapy should be to achieve a near normal glycemic variability. Achieving such a goal needs further improvements in insulin delivery systems.

Study context

Population
People with T1D treated with SAP (Sensor Augmented Pump) or AID38 RCTs
Primary endpoint
%CV glucose threshold below which hypoglycaemia risk is minimised or eliminated

Primary result

As reported in the abstract

Mean reduction in %CV glucose (percentage points) associated with a mean decrease in TBR <70 mg/dL of ≈0.50 % (percentage points)

2.0 %

%CV glucose below which hypoglycaemia risk becomes negligible

27 %

%CV glucose below which hypoglycaemia risk is eventually eliminated

19 %
