- Several findings obtained recently indicate that inflammation may contribute to the pathogenesis in Parkinson's disease (PD). Genetic variants of genes coding for components involved in immune reactions in the brain might therefore influence the risk of developing PD or the age of disease onset. Five single nucleotide polymorphisms (SNPs) in the genes coding for interferon-gamma (IFN-gamma; T874A in intron 1), interferon-gamma receptor 2 (IFN-gamma R2; Gln64Arg), interleukin-10 (IL-10; G1082A in the promoter region), platelet-activating factor acetylhydrolase (PAF-AH; Val379Ala), and intercellular adhesion molecule 1 (ICAM-1; Lys469Glu) were genotyped, using pyrosequencing, in 265 patients with PD and 308 controls. None of the investigated SNPs was found to be associated with PD; however, the G1082A polymorphism in the IL-10 gene promoter was found to be related to the age of disease onset. Linear regression showed a significantly earlier onset with more A-alleles (P = 0.0095; after Bonferroni correction, P = 0.048), resulting in a 5-year delayed age of onset of the disease for individuals having two G-alleles compared with individuals having two A-alleles. The results indicate that the IL-10 G1082A SNP could possibly be related to the age of onset of PD.

Mass spectrometric identification of aldonolactones as trimethylsilyl derivatives

- Trimethylsilyl ethers of aldonolactones are useful for the identification of aldonic acids by mass spectrometry. Peaks recorded for the molecular ion (M) and for mass M-15 give a reliable determination of the molecular weight. Significant differences exist between 1,4- and 1,5-lactones. All diastereomers studied can be well distinguished from each other.

- Background: Continuous infusion of levodopa-carbidopa intestinal gel (LCIG) can effectively manage motor and non-motor complications in advanced Parkinsons disease (PD). Healthcare costs, quality of life (QoL), effectiveness, and tolerability were assessed in routine care treatment with LCIG. Methods: The seventy-seven patients enrolled in this prospective, open-label, 3-year study in routine medical care were LCIG-naive (N = 37), or had previous LCIG treatment for amp;lt;2 (N = 22), or amp;gt;= 2 (N = 18) years. Healthcare costs were collected monthly. PD symptoms and QoL were assessed with the Unified Parkinsons Disease Rating Scale (UPDRS), 39-item Parkinsons Disease Questionnaire (PDQ-39), and EuroQoL 5-Dimension Visual Analog Scale (EQ-5D VAS); LCIG dose, safety, and tolerability were monitored. Results: Mean monthly costs per patient ( 8226 5952) were similar across cohorts, remained steady during 3-year follow-up, and increased with PD severity and QoL impairment. In LCIG-naive patients, significant improvements compared to baseline were observed on the UPDRS total score and PDQ-39 summary index score through 18 months (n = 24; UPDRS, p = 0.033; PDQ-39, p = 0.049). Symptom control was maintained during 3-year follow-up in LCIG-experienced cohorts. Small changes in mean daily LCIG dose were observed. Adverse events were common and generally related to the device, procedure, levodopa, or laboratory evaluations. Conclusions: Costs in LCIG-treated patients were stable over 3 years. LCIG treatment led to significant improvements in motor function and QoL over 18 months in LCIG-naive patients and no worsening was observed in LCIG-experienced patients over 3 years despite natural PD progression over time. The longterm safety was consistent with the established LCIG profile. (C) 2016 AbbVie Inc. Published by Elsevier Ltd.

- INTRODUCTION: Genetic variants in the Beta-glucocerebrosidase gene (GBA1) is a known risk factor for Parkinson's disease. The GBA1 mutations L444P, N370S and many other have been shown to associate with the disease in populations with diverse background. Some GBA1 polymorphisms have a less pronounced effect, and their pathogenicity has been debated. We have previously found associations with L444P, N370S and E326K and Parkinson's disease in Sweden.METHOD: In this study we used pyrosequencing to genotype the T369M variant in a large Swedish cohort consisting of 1,131 patients with idiopathic Parkinson's disease, and 1,594 control subjects to evaluate the possibility of this variant conferring an increased risk for Parkinson's disease.RESULTS: The minor allele frequency was 2.15% in patients and 1.76% in controls. Statistical analysis showed that there was no significant difference in allele frequency between patients and control subjects, p-value 0.37, Odds Ratio 1.23 with a 95% confidence interval of 0.82-1.83.CONCLUSION: Our results suggest that T369M is not a risk factor for Parkinson's disease in the Swedish population.

- The serine-protease OMI/HTRA2, required for several cellular processes, including mitochondrial function, autophagy, chaperone activity, and apoptosis, has been implicated in the pathogenesis of both Alzheimer's disease (AD) and Parkinson's disease (PD). Western blot quantification of OMI/HTRA2 in frontal cortex of patients with AD (n=10) and control subjects (n=10) in two separate materials indicated reduced processed (active, 35 kDa) OMI/HTRA2 levels, whereas unprocessed (50 kDa) enzyme levels were not significantly different between the groups. Interestingly, the specific protease activity of OMI/HTRA2 was found to be significantly increased in patients with AD (n=10) compared to matched control subjects (n=10) in frontal cortex in two separate materials. Comparison of OMI/HTRA2 mRNA levels in frontal cortex and hippocampus, two brain areas particularly affected by AD, indicated similar levels in patients with AD (n=10) and matched control subjects (n=10). In addition, we analyzed the occurrence of the OMI/HTRA2 variants A141S and G399S in Swedish case-control materials for AD and PD and found a weak association of A141S with AD, but not with PD. In conclusion, our genetic, histological, and biochemical findings give further support to an involvement of OMI/HTRA2 in the pathology of AD; however, further studies are needed to clarify the role of this gene in neurodegeneration.
