ABSTRACTBackground: To evaluate the effect of autologous hematopoietic CD34+ cell transplantation (HCT) on diabetic neuropathy in patients with type 2 diabetes mellitus.
Materials and Methods: We recruited ambulatory patients with type 2 diabetes and diabetic neuropathy as defined by the consensus of San Antonio without other active comorbidities. After s.c. filgrastim administration for 4 days, patients were randomized to a treatment group (intervened with autologous intramuscular HCT on the gastrocnemius region) or to a placebo group (intervened with autologous intramuscular plasma on the same region). Patients were evaluated by blinded personnel at the beginning and 3 months later by nerve conduction velocities (NCV) of lower extremities. Successful outcomes were defined as an improvement in NCV.
Results: Twenty patients were included, 15 in the treatment group and 5 in the placebo group. Both groups had successful outcomes in the left peroneal NCV, independent of the number of CD34+ cells transplanted. The differences between groups were not statistically significant.
Conclusions: Although we found improvement in NCV with autologous HCT, we propose further studies to determine the effect of transplantation on diabetic neuropathy.
