About this trial
The GLUREDIA study investigates the counter-regulatory response (CRR) during hypoglycemia in children with type 1 diabetes (T1D). Hypoglycemia can lead to severe symptoms, but is normally counteracted by CRR, corresponding to the secretion of hormones to maintain normoglycemia. Hypoglycemia is common in T1DM but some patients develop severe hypoglycemia as a result of CRR dysfunction. Despite several studies in adults, the presence of CRR dysfunction remains unpredictable and not well understood. The objective of GLUREDIA is therefore to describe and predict the evolution of CRR in children with T1DM.
Eligibility criteria
Qualifiers
De novo type 1 diabetic patient, as per ISPAD criteria;
Symptoms of hyperglycemia: polyuria-polydipsia-amaigrin +/- Acido ketosis.
Fasting blood glucose ≥126 mg/dL AND/OR blood glucose ≥200 mg/dL at 120 minutes of an OGTT AND/OR HbA1c ≥6.5% AND/OR a patient with symptoms of hyperglycemia/hyperglycemic crisis (see 8. a. 2.) with random blood glucose ≥200 mg/dL.
Patients aged between 2 and 30 years
Disqualifiers
Child under 2 years of age.
