Session: SAT 834-867-Islet Biology
Bench to Bedside
Poster Board SAT-866
Methods: Eighteen patients with type 1 diabetes aged 6-40 years were included in the study. Each patient intravenously received fetal liver derived hematopoietic stem cells from human legally aborted early fetus aged 6 -12 weeks. The patients had been followed up for 2 years and their plasma glucose as well as HbA1C levels were monitored over this period. This study was approved by the ethical committee of Tehran University of Medical Sciences and Iranian Registry of Clinical Trials
Results: Blood glucose levels gradually decreased within the first day after the treatment in 5/18 patients. Daily insulin requirement of these 5 patients was (0.35-0.70 u/kg/day) before the intervention. 2/5 patients stayed constantly insulin free for 16 and 24 months. In other patients, there were no significant changes in their condition.
Conclusion: In this study, it was observed that fetal hematopoietic stem cell transplantation in patients with type 1 diabetes was successful in diabetes treatment to some extent. Moreover, using no immunosuppressive agents before and after the transplantation according to the low immunogenicity of fetal hematopoietic stem cells can be considered as an advantage to this new therapeutic modality However, further clinical trials with larger number of patients and long term follow- ups would be useful to confirm our results.
