New study tracks diabetes progression in younger vs older patients
NCT ID NCT07574138
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 296 Vietnamese adults with type 2 diabetes for one year to compare how insulin-producing beta cells change in people diagnosed before age 40 versus those diagnosed at 40 or older. Researchers will measure blood markers like C-peptide and HbA1C at 3, 6, 9, and 12 months. The goal is to understand if early-onset diabetes leads to faster loss of beta cell function, which could guide future treatment approaches.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * The patient is diagnosed with Type 2 Diabetes Mellitus according to the ADA 2024 criteria (Fasting Glucose ≥ 126 mg/dl, or Glucose after 2 hours of an Oral Glucose Tolerance Test ≥ 200 mg/dl, or HbA1C ≥ 6.5%, or with typical symptoms accompanied by any Glucose ≥ 200 mg/dl). * The duration of Type 2 Diabetes Mellitus does not exceed 10 years. * Classification by age of onset: Early onset group (\< 40 years) and typical onset group (≥ 40 years). * At least 6 months without the need for insulin and no recorded episodes of diabetic ketoacidosis since the time of diagnosis. * For the early-onset group: Autoantibodies (Anti-GAD, ICA) are negative and fasting C-peptide levels are \> 0.6 nmol/L. * The patient consents to participate in the study and signs the informed consent document. Exclusion Criteria: * Pregnant women or patients with acute illnesses at the time of assessment. * The patient has been diagnosed with or exhibits characteristics suggestive of Type 1 Diabetes Mellitus (such as a history of ketoacidosis, C-peptide \< 0.2 nmol/L). * Secondary diabetes mellitus due to pancreatic disorders (pancreatitis, pancreatic tumors, pancreatic resection), due to medications (glucocorticoids), or due to other endocrine disorders (Cushing's syndrome, hyperthyroidism, acromegaly). * Severe renal failure with an estimated glomerular filtration rate (eGFR) \< 30 mL/min/1.73 m². * Use of medications that affect beta cell function or complications such as prolonged high-dose corticosteroids, immunosuppressive agents, or chemotherapy. * Not of Vietnamese ethnicity. * Non-compliance with treatment guidelines or failure to attend scheduled follow-up appointments.
