We previously reported clinical improvement, increase in putamen [(18)F]-dopa uptake on PET imaging, and neuropathologic evidence of sprouting of dopaminergic fibers following chronic intraputaminal delivery of glial cell line-derived neurotrophic factor (GDNF) in idiopathic Parkinson disease (PD).(1-3) We now provide clinical and PET evidence of persistent efficacy lasting for at least 3 years following cessation of GDNF infusion in a patient with PD. This is a single-case observational study, providing Class IV evidence.
我们之前曾报道过一例临床改善的病例,该患者患有特发性帕金森病(PD),在接受胶质细胞源性神经营养因子(GDNF)慢性脑内给药后,纹状体[(18)F]-多巴摄取增加,且 PET 成像显示多巴胺能纤维有发芽现象。(1-3)我们现在提供了一名 PD 患者停止 GDNF 输注后至少 3 年持续有效的临床和 PET 证据。这是一项单病例观察研究,提供了 IV 级证据。
