Evaluate Safety of Adipose Derived Mesenchymal Stem Cell Transplantation for Type 1 Diabetes Treatment

Adipose derived mesenchymal stem cells (AD-MSCs) has many advantages, i.e. the greater ease of access and harvesting by means such as subcutaneous lipoaspiration, a much less painful procedure than harvesting bone marrow stem cells, and a much less ethical concern because they are harvested from autologous fat. The purpose of this study is to evaluate the safety of intravenously (IV) administered adipose-derived mesenchymal stem cell (AD-MSC) in treatment 10 patients with type 1 diabetes mellitus (T1D) at Vinmec International Hospital, Hanoi, Vietnam.

Inclusion criteria

• Patient diagnosed T1D (according to the instructions of the Ministry of Health No: 5481/QD-BYT dated December 30, 2020)
• Aged from 5 years and over.
• The time from the diagnosis of type 1 diabetes to enrollment ≤ 12 months.
• Blood testing conducted at the time of diagnosis:

• Fasting blood glucose ≥ 7 mmol / L,
• HbA1C ≥ 6.5%.
• Have at least one antibodies associated with T1D such as ICA; GAD; ZnT8 or IAA.
• At the time of screening at Vinmec for study enrollment, patients are actively managing their blood glucose levels with insulin.
• The patient does not have other serious acute illness requiring treatment
• The patient agrees to use stem cell transplant for treatment
• The patient's parent (parent or legal guardian) can read, write, understand the ICF form and agree to sign a consent to participate in the study.
