cArdiopulmonary exerCise Test Assessing Multiple bIOmarkers iN Type 1 Diabetes

15 de octubre de 2021 actualizado por: Christophe De Block, University Hospital, Antwerp
Collection of venous blood samples in male T1D patients to evaluate the behavior of different biomarkers (beta-hydroxybutyrate, lactate, glucose) during and after morning Aerobic (60% of VO2 max) and Symptom Limited Maximal Exercise Test.

Descripción detallada

Compare values and trends of different biomarkers (glucose, lactate and beta-hydroxybutyrate) before, during and after morning aerobic and symptom limited maximal exercise (cycling) to predict glycemic fluctuations (hypo- and hyperglycemic events) during and after exercise in order to create treatment algorithms to prevent these events.

Endpoint:

• Evaluate values and trends of glucose, lactate and beta-hydroxybutyrate before, during and after morning exercise in venous blood.

Descripción

Inclusion Criteria:

  • Male adults (18-40 years old) with T1D, diagnosed since > 1 year

Exclusion Criteria:

  • Recently diagnosed T1D (< 12mo)
  • Participants not on MDI or CSII
  • Musculoskeletal disorder that affects cycling or is a contra-indication for vigorous physical activity
  • Cardiorespiratory disease or ECG abnormality that is a contra-indication for vigorous physical activity
  • Having an acute illness (e.g. influenza) that interferes with glucose metabolism
  • Having a metabolic disorder (different from diabetes) or takes drugs known to have significant interference with glucose metabolism, such as systemic corticoids as judged by the investigator
  • Current treatment with drugs known to have significant interference with glucose metabolism, such as systemic corticoids as judged by the investigator
  • Presence of concomitant pathology such as heart failure, liver failure, kidney failure defined as eGFR <45mL/min
  • Patient not able or willing to sign the patient informed consent

Blood sampling was done before the exercise, every 3 minutes for CPET and every 5 minutes for AEX during the exercise and every 15 minutes during the first hour of recovery and every 20 minutes during the rest of the 6-hour follow-up.
Change in lactate concentration during and after morning Aerobic and Symptom Limited Maximal Exercise Test
Periodo de tiempo: Blood sampling was done before the exercise, every 3 minutes for CPET and every 5 minutes for AEX during the exercise and every 15 minutes during the first hour of recovery and every 20 minutes during the rest of the 6-hour follow-up.
Lactate levels in mmol/mol during and after morning Aerobic (60 minutes at 60% of VO2 max) and Symptom Limited Maximal Exercise Test (AEX & CPET), measured in 21 patients through YSI (YSI Life Sciences, Yellow Springs, OH)
