Objective  To systematically review the effectiveness and safety of autologous implantation of stem cells for diabetic peripheral neuropathy (DPN).
Methods  Randomized controlled trials on relevant studies were retrieved in databases including CBM (1978-2011.6), CNKI (1979-2011.6), MEDLINE (1950-2011.6), PubMed (1950-2011.6), EMbase (1970-2011.6) and The Cochrane Library (Issue 3, 2011). References of the included studies were also retrieved. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assess the methodological quality of the included studies. Then, meta-analysis was performed using RevMan 5.0 software.
Results  Four RCTs involving 68 patients (136 limbs) were included, most of which were low in methodological quality. The results of meta-analysis indicated that, autologous stem cell therapy improved or even eliminated DPN symptoms including pain, numbness, and cold sensation in the limbs, intermittent limping, and rest pain. Compared with the routine therapy, autologous stem cell therapy improved tibial sensory nerve conduction velocity (MD=5.75, 95%CI 3.86 to 7.64, P lt;0.000 01), tibial motor nerve conduction velocity (MD=4.04, 95%CI 0.90 to 7.18, P=0.001), sural sensory nerve conduction velocity (MD=7.47, 95%CI 4.00 to 10.94, P lt;0.000 1), and sural motor nerve conduction velocity (MD=3.38, 95%CI 0.07 to 7.58, P=0.05), with no adverse reaction reported.
Conclusion  Current evidence shows that, autologous stem cell therapy is effective in treating DPN. Due to the lack of high quality studies, more high quality RCTs are needed to verify the above conclusion.
