There are 2 clinical trials
The primary objective of this protocol is to access the utility of 18F-DTBZ PET imaging as an in vivo biomarker to monitor neurodegeneration of both PD mouse models and PD patients. Secondary, the investigators will analyze progression rate of genetic-proving PARK8 and PARK6 patients who have homogeneous phenotype and genotype by 18F-DTBZ PET imaging.
The annual decline rate of striatal 18F-DTBZ SUVRs (specific uptake value ratios) in PD patients carrying LRRK2 G2385R mutation, PARK6 patients, and patients with idiopathic PD, respectively.. To analyze the correlation between decline rate of 18F-FP-(+)-DTBZ uptake and clinical severity, and access the feasibility of 18F-DTBZ PET imaging as an in vivo biomarker to monitor neurodegeneration in PD. --- G2385R ---
3. Twenty PD patients were proved carrying LRRK2 G2385R mutation by our genetic laboratory. --- G2385R ---
Parkinson's Disease Parkinson Disease Parkinsonian Disorders Nerve Degeneration Total of 60 patients, 20 LRRK2 G2385R, 20 PARK6, and 20 idiopathic PD, will be recruited. --- G2385R ---
Description: The annual decline rate of striatal 18F-DTBZ SUVRs (specific uptake value ratios) in PD patients carrying LRRK2 G2385R mutation, PARK6 patients, and patients with idiopathic PD, respectively.
Measure: To calculate the decline rate of striatal 18F-FP-(+)-DTBZ binding and to evaluate whether the degenerative rate differs between idiopathic PD patients and genetic-proving PARK6/PARK8 patients Time: 2 yearsDescription: To analyze the correlation between 18F-FP-(+)-DTBZ annual decline rate and the progression rate of clinical motor scores/non-motor scores/ neuropsychiatric tests in each group. Furthermore, to access the utility of 18F-DTBZ PET imaging as an in vivo biomarker to monitor neurodegeneration in PD patients.
Measure: To analyze the correlation between decline rate of 18F-FP-(+)-DTBZ uptake and clinical severity, and access the feasibility of 18F-DTBZ PET imaging as an in vivo biomarker to monitor neurodegeneration in PD Time: 1 yearThe purpose of the Chinese PD-LRRK2 Registry(CPD-LRRK2R) is to develop a database of patients of Parkinson's disease with leucine-rich repeat kinase 2 (LRRK2) gene variants in mainland China.
However, some polymorphisms of LRRK2 such as G2385R and R1628P can also affect the risk of developing PD. --- G2385R ---
Description: Establish the database of Parkinson's disease with LRRK2 variants in mainland China.
Measure: Database of Parkinson's disease with LRRK2 variants Time: 10 yearsDescription: Characterize the clinical feature in patients of Parkinson's disease with LRRK2 variants
Measure: Clinical feature Time: 10 years
