Abstract
OBJECTIVE Parkinson's disease (PD) is a common neurodegenerative disease, but its nutritional problems have not received enough attention. This study aims to identify the prevalence and associated factors of malnutrition in PD patients using two simple nutritional tools. METHODS We conducted a large-scale cross-sectional study with 1478 PD patients and equal healthy controls (HC). The controlling nutritional status score (CONUT) and geriatric nutritional risk index (GNRI) were used for malnutrition stratification. RESULTS By CONUT or GNRI, the prevalence of malnutrition in PD patients was higher than that in HC (40.7% vs. 25.3% and 11.1% vs. 2.1%, respectively). The binary logistic regression model showed that malnutrition in PD was associated with male sex (OR = 0.600, P < 0.001), older age (OR = 1.015, P = 0.003), lower body mass index (BMI) (OR = 0.942, P < 0.001), higher levodopa equivalent daily doses (LEDD) (OR = 1.001, P < 0.001), worse motor symptoms (OR = 1.012, P = 0.004), more serious perceptual problems/hallucinations (OR = 1.067, P = 0.019) by CONUT. In comparison, older age (OR = 1.045, P < 0.001), lower blood lymphocyte count (OR = 0.607, P = 0.006), lower serum total cholesterol levels (OR = 0.991, P < 0.001), dyskinesia (OR = 2.231, P = 0.002), worse motor symptoms (OR = 1.016, P = 0.015), more severe depression (OR = 1.028, P = 0.008) and perceptual problems/hallucinations (OR = 1.061, P = 0.033) were associated with malnutrition in PD by GNRI. CONCLUSIONS Our study indicated that malnutrition is more prevalent in PD patients than HC. Multidimensional risk factors for malnutrition in PD should be taken seriously.

Zheng J, Zang Q, Hu F, Wei H, Ma J, Xu Y. Alpha-synuclein gene polymorphism affects risk of dementia in Han Chinese with Parkinson's disease. Neurosci Lett 2019; 706:146-150. [PMID: 31102707 DOI: 10.1016/j.neulet.2019.05.026] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2018] [Revised: 04/30/2019] [Accepted: 05/14/2019] [Indexed: 02/05/2023]
Abstract
BACKGROUND Single-nucleotide polymorphisms (SNPs) in the SNCA gene encoding alpha-synuclein have been shown to affect the PD phenotype. However, whether such polymorphisms can influence risk of dementia in PD remains unclear. OBJECTIVES To investigate possible associations between SNCA gene polymorphisms and dementia in patients with PD. MATERIALS AND METHODS A consecutive series of 291 PD patients with dementia (n = 45, 15.5%) or without it (n = 246, 84.5%) were genotyped at four SNPs in the SNCA gene. As controls, 615 healthy Han Chinese were also genotyped. RESULTS Three SNPs (rs11931074, rs7684318 and rs356219) were in strong linkage disequilibrium. The GG genotype at rs11931074 significantly reduced risk of PD (p = 0.023), but it significantly increased risk of dementia after PD onset (p = 0.015) based on the recessive genetic model. Logistic regression identified the following risk factors for dementia among patients with PD: age ≥65 years (odds ratio [OR] 2.69, 95% confidence interval [CI] 1.25-5.77, p = 0.011), education ≤6 years (OR 4.66, 95% CI 2.21-9.83, p < 0.001), part III score on the Unified Parkinson's Disease Rating Scale ≥40 (OR 5.01, 95% CI 2.40-10.45, p < 0.001), and GG genotype at rs11931074 (OR 2.81, 95% CI 1.16-6.83, p = 0.022). CONCLUSIONS PD patients carrying the protective GG genotype at SNCA rs11931074 may be at significantly higher risk of dementia than patients with other genotypes. Our results support the view that SNCA polymorphisms can have opposite effects on preclinical and clinical PD.

Festination Correlates with SNCA Polymorphism in Chinese Patients with Parkinson's Disease. PARKINSONS DISEASE 2017; 2017:3176805. [PMID: 28357149 PMCID: PMC5357534 DOI: 10.1155/2017/3176805] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/27/2016] [Revised: 02/17/2017] [Accepted: 02/20/2017] [Indexed: 02/05/2023]
Abstract
The genetic basis of festination, a common motor symptom in Parkinson's disease (PD), remains unclear. Since polymorphism in the alpha-synuclein (SNCA) gene is associated with PD phenotype, we examined whether such polymorphism is also associated with festination. SNCA polymorphisms rs11931074 and rs894278 were genotyped in a consecutive series of 258 patients with PD, of whom 122 (47.3%) suffered festination. Univariate analysis revealed significant differences in genotype and minor allele frequencies at rs11931074 or rs894278 between patients with festination and those without it (all p < 0.05). Based on logistic regression, a GG or GT genotype at rs11931074 was associated with higher risk of festination among patients with PD (OR 2.077, 95% CI 1.111–3.883, p = 0.022), as was the TT genotype at rs894278 (OR 2.271, 95% CI 1.246–4.139, p = 0.007). Therefore, we conclude that festination is associated with polymorphism at rs11931074 or rs894278 among patients with PD.
