T1D & COMPLICATIONS

Chronic complications versus glycaemic variability, time in range and HbA1c in people with type 1 diabetes: substudy of the RESCUE-trial

Presented by:

Anass El Malahi, MD


  • In T1D, HbA1c and duration of diabetes are important risk factors for the development of chronic complications.
  • A shorter TIR is associated with several microvascular complications, and especially retinopathy.
  • TIR is also associated with hospitalization for hypoglycaemia or ketoacidosis.

What do we already know about this topic?

  • Self-monitoring of blood glucose provides an incomplete picture of glucose control.1
  • Continuous glucose monitoring (CGM) can give a more comprehensive picture of glycaemic variability (GV) and time spent in range (TIR).2
  • There are few studies examining the relationship between GV or TIR and chronic complications.

How was this study conducted?

  • Parameters that could have a link with diabetes complications were analysed in 515 adults with type 1 diabetes (T1D) who entered the Belgian reimbursement system in terms of real-time CGM, HbA1c, standard deviation (SD), coefficient of variation, TIR (70-180 mg/dL), age, duration of diabetes, BMI and gender.
  • Association between glucometrics from the first 2 weeks of CGM use and presence of diabetes complications were investigated with multiple logistic regression.

What does this study add?

  • Higher TIR was associated with fewer microvascular complications, with no association with macrovascular complications.
  • Diabetes duration (OR = 1.12, p <0.001) and TIR (OR = 0.97, p = 0.005) were independently correlated with composite microvascular complications.
  • For nephropathy, diabetes duration (OR = 0.97, p <0.001) and HbA1c (OR = 1.65, p = 0.12) were independently associated.
  • For retinopathy, diabetes duration (OR = 0.14, p <0.001) and TIR (OR = 0.96, p <0.001) were independently associated.
  • Age (OR = 1.08, p = 0.003) and HbA1c (OR = 1.80, p = 0.44) were independently associated with macrovascular complications.
  • Only TIR (OR = 0.97, p = 0.021) was independently associated with hospitalization for hypoglycaemia or ketoacidosis.

Perspectives

How does this study impact clinical practice?

  • HbA1c and duration of diabetes remain important independent risk factors for chronic complications in T1D.
  • A shorter TIR was associated with the presence of composite microvascular complications, and with retinopathy in particular.
  • A high SD was linked to peripheral and autonomic neuropathy.
  • For hospitalization for hypoglycaemia or ketoacidosis, TIR was the most important factor.
