This study evaluates the effectiveness of autologous non-myeloablative hematopoietic stem cell transplantation (AHSCT) for adolescents with type 1 diabetes experiencing diabetic ketoacidosis (DKA) at diagnosis. Enrolling 28 patients aged 14–30, the trial measured changes in insulin requirements and levels of HbA1c, C-peptide, and anti-glutamic acid decarboxylase antibody before and after AHSCT. Results indicate that AHSCT may offer significant benefits, particularly in patients without DKA at diagnosis, leading to long-term insulin independence.

Study Objectives • To determine whether autologous nonmyeloablative hematopoietic stem cell transplantation (AHSCT) was beneficial for type 1 diabetic adolescents with diabetic ketoacidosis (DKA) at diagnosis Gu W et al. Diabetes Care 2012;35:1413-1419
Study Design • Enrolled 28 patients with type 1 diabetes, aged 14–30 years, in a prospective AHSCT phase II clinical trial • HSCs harvested from peripheral blood after pretreatment consisting of cyclophosphamide and antithymocyte globulin • Changes in the exogenous insulin requirement and serum levels of HbA1c, C-peptide, and anti-glutamic acid decarboxylase antibody measured before and after the AHSCT Gu W et al. Diabetes Care 2012;35:1413-1419
Conclusions • AHSCT appears to be an effective long-term treatment for insulin dependence that achieved a greater efficacy in patients without DKA at diagnosis Gu W et al. Diabetes Care 2012;35:1413-1419
