Abstract

Fetal ventral mesencephalon (VM) transplantation has been reported to improve Parkinsonian symptoms. Animal studies show that cografting of striatal tissue increases the survival of dopamine neurons. Whether or not VM and striatum cografting could ameliorate motor dysfunction in a Parkinson's disease (PD) patient was explored in this study. The patient was a 53-year-old male who had presented with symptoms of tremor, rigidity and bradykinesia for 11 years. He had been treated with L-dopa and had progressive deterioration of symptoms even with the daily dosage of L-dopa increased to 900 mg per day. Before transplantation, his PD symptoms were scored with Unified Parkinson's Disease Rating Scale (UPDRS) and video recordings. The influx constant (ki) of the [18F] 6-fluoro-L-dopa uptake in the striatum was measured by positron emission tomography (PET) imaging. The fetal VM and the lateral part of the lateral ganglionic eminence (LGE) were cografted into the right putamen and, one week later, fetal VM alone was transplanted into the left putamen. After the transplantation, the patient's UPDRS score improved from 128 to 62 at 6 months and to 24 at 22 months during the "off" phase. The score of daily living disability improved from 35 to 18 at 6 months and to 10 at 22 months post transplantation. Twenty-two months after grafting, "off" phases were almost absent, and the freezing had totally disappeared. The [18F] 6-fluoro-L-dopa PET studies were performed 1 month before and 21 months after transplantation. The ki for [18F] 6-fluoro-L-dopa was decreased by 15% in the right caudate and 5% in the left caudate, both of which did not have any ventral mesencephalic grafts. However, the ki was increased by 35% in the left non-cografted putamen, and by 58% in the right cografted putamen. In conclusion, cografting the fetal VM and the LGE in the putamen may improve the motor function of PD patients.
