Intraarterial Autologous Implantation of Adult Stem Cells for Patients with Parkinson Disease

Purpose To evaluate the feasibility, safety, and effectiveness of intraarterial autologous implantation of adult stem cells for Parkinson disease (PD). Materials and Methods From June 2006 to August 2008, 36 men and 14 women (mean age, 62.5 years ± 10.4; range, 38–81 y) with PD (mean duration, 9.3 years; range, 1–28 y) underwent autologous implantation of stem cells with superselective arterial catheterization. Patients were evaluated with clinical and neurologic examinations; internationally recognized scales for the evaluation of PD, disability, activities of daily living, depression, and quality of life (QOL); as well as videos, magnetic resonance (MR) imaging, and MR spectroscopy. Stem cells were implanted in the posterior region of the circle of Willis. Patients were evaluated according to clinical measures. Comparison was made versus data collected from all scales before treatment, as well as videos and spectroscopy in eight patients. Results In a mean follow-up of 7.4 months ± 4.5 (range, 1–18 months), patients showed a median improvement of 51.1% and quartile deviation (QD) of 24.8% on the Unified PD Rating Scale. They showed significant improvement in disability, activities of daily living, depression, and QOL ( P P Conclusions Treatment of PD with intraarterial autologous implantation of adult stem cells is feasible and safe and results in improved severity of disease and QOL.
