    Abstract Objective: It is difficult to distinguish patients with schizophrenia with neuroleptic-induced parkinsonism (NIP) from those with existing idiopathic Parkinson's disease when their striatal dopamine transporter uptake is reduced. There is a possibility of misdiagnosis of Parkinson's disease in patients with schizophrenia as schizophrenia with NIP, which leads to inappropriate treatment. This prospective study aimed at determining the underlying pathophysiology using detailed clinical and psychological assessments.
    Methods: We enrolled six patients with schizophrenia who had parkinsonism and were diagnosed with Parkinson's disease according to the Movement Disorder Society Clinical Diagnostic Criteria, except for the fifth absolute exclusion criteria.
    Results: Five patients had been treated with neuroleptics for 20 years. One patient refused treatment for schizophrenia. All patients had impaired cognitive function at enrolment, olfactory dysfunction, and constipation. All patients were treated with dopaminergic therapy, and their parkinsonism substantially improved; one woman in her 40s experienced a wearing-off effect and dyskinesia. The uptake of dopamine transporter in the striatum decreased by 13%/year during the study period.
    Conclusion: Some patients with schizophrenia and parkinsonism benefit from dopaminergic therapy. Some of these patients may also exhibit Lewy pathology.

    Abstract We previously assessed the prevalence and risks of motor/nonmotor symptoms in a large sample of Japanese patients with Parkinson's disease. In the present study, we longitudinally assessed the prevalence and risk of motor/nonmotor symptoms, changes in treatment, disease progression, and death in patients with Parkinson's disease. We enrolled 1,227 patients diagnosed and treated at our hospital in Tokyo at first evaluation. We were able to follow-up 445 patients until the second evaluation, 7.4 years later. Using Kaplan-Meier survival curves and the Cox proportional-hazards model in 1,227 patients, motor/nonmotor symptoms were analyzed in association with the following events: pain, wearing-off, camptocormia, psychosis, orthostatic hypotension, pneumonia, tube feeding, modified Hoehn and Yahr stages (H-Y) 3 and 4 of the on state, and death. The mean age (standard deviation) at the first evaluation was 67.2 (9.9) years, while the mean ages at onset and disease duration were 57.8 (11.7) years and 9.3 (6.6) years, respectively. The mean H-Y of the on state was 2.7 (1.1) at the first evaluation. Age at onset and duration of levodopa use decreased the hazard ratios (HRs) (0.968 and 0.910, respectively) for wearing-off. Female sex increased the HRs (1.414) for wearing-off and decreased the HRs for orthostatic hypotension (0.540) and pneumonia (0.510). Older age at onset increased the HR for psychosis (1.035), orthostatic hypotension (1.033), H-Y 3 (1.048) and 4 (1.071), pneumonia (1.123), tube feeding (1.140), and death (1.095). Early onset of orthostatic hypotension itself increased the HR for numerous events, especially for death (0.893). Our results indicated that age, sex, and some nonmotor symptoms may predict many Parkinson's disease-related events. In addition, these data may provide a useful reference for the clinical course of Parkinson's disease.

    Abstract Background: Camptocormia in Parkinson's disease (PD) is unresponsive to various therapies and induced difficulties in their day-to-day life.
    Objective: This study, an open trial, was aimed at assessing the efficacy of selegiline in the treatment of mild camptocormia in PD patients.
    Methods: Participants were administered 5 mg of selegiline for the first 8 weeks and 7.5 mg for the second 8 weeks.
    Results: As primary endpoints, the degree of thoracolumbar anteflexion decreased from 23.2° (mean) (11.8° (SD)) at baseline to 18.3° (7.1°) at 16 weeks, and the area of postural sway measured using a Gravicorder increased. However, the differences were not significant. Thoracolumbar anteflexion improved in 60% of the participants.
    Conclusions: In this study, 60% of the participants showed an improvement in anteflexion of the thoracolumbar spine with selegiline, but the change in the degree of anteflexion was 5°, which was not statistically significant. Participants with significant improvement in thoracolumbar anteflexion had an increased postural sway. This change was induced by a decrease in truncal muscle tonus or change in the center of gravity. This study combined the study of anteflexion and stability, and provides information on the treatment of short-term or mild camptocormia.

    Abstract Hyposmia is one of the earliest and the most common symptoms in Parkinson's disease (PD). The benefits of hydrogen water on motor deficits have been reported in animal PD models and PD patients, but the effects of hydrogen gas on PD patients have not been studied. We evaluated the effect of inhalation of hydrogen gas on olfactory function, non-motor symptoms, activities of daily living, and urinary 8-hydroxy-2'-deoxyguanine (8-OHdG) levels by a randomized, double-blinded, placebo-controlled, crossover trial with an 8-week washout period in 20 patients with PD. Patients inhaled either ~1.2-1.4% hydrogen-air mixture or placebo for 10 minutes twice a day for 4 weeks. Inhalation of low dose hydrogen did not significantly influence the PD clinical parameters, but it did increase urinary 8-OHdG levels by 16%. This increase in 8-OHdG is markedly less than the over 300% increase in diabetes, and is more comparable to the increase after a bout of strenuous exercise. Although increased reactive oxygen species is often associated with toxicity and disease, they also play essential roles in mediating cytoprotective cellular adaptations in a process known as hormesis. Increases of oxidative stress by hydrogen have been previously reported, along with its ability to activate the Nrf2, NF-κB pathways, and heat shock responses. Although we did not observe any beneficial effect of hydrogen in our short trial, we propose that the increased 8-OHdG and other reported stress responses from hydrogen may indicate that its beneficial effects are partly or largely mediated by hormetic mechanisms. The study was approved by the ethics review committee of Nagoya University Graduate School of Medicine (approval number 2015-0295). The clinical trial was registered at the University Hospital Medical Information Network (identifier UMIN000019082).

    Abstract Objective Many studies on the cost of Parkinson disease (PD) have been published; however, there are limited studies pertaining to this issue in Asia. This study looks to assess the direct medical costs of patients with PD at a university hospital in Japan by calculating the average monthly direct medical costs of PD patients from July to December 2008. Methods We enrolled 724 consecutive patients (411 women and 313 men) with PD who were registered in Japan's "Specified Disease Treatment Research Program" and obtained data on the total direct medical costs of all patients. Results Values are reported as the mean (standard deviation). The major finding of the direct medical cost analysis was that the outpatient clinic cost per subject (n=715) was USD 485.74 (376.31) per month. A multivariate analysis revealed that a younger age, the presence of wearing-off, hallucination, and longer disease duration increased the direct medical cost significantly. Disease severity had no influence on the direct medical costs. A longer disease duration was significantly correlated with higher hospitalization costs. Conclusion The direct medical cost of PD in Japan was found to be similar to that in Western countries. Costs due to productivity loss exceeded the direct costs, and they may be reduced through the better integration of PD patients in the work environment.

    Abstract To investigate the prevalence and genotype-phenotype correlations of parkin RBR E3 ubiquitin protein ligase (PRKN) variants in Parkinson's disease (PD), we first included 2,527 patients with PD. Through the defined selection, we enrolled 2,322 patients, including 1,204 with familial and 1,118 with sporadic PD. We identified 242 patients harboring PRKN variants, which were thought to be susceptibility factors, comprising 137 patients with familial and 105 with sporadic PD; among the 26 identified variants, 13 were novel. We divided our cohort into 2 groups: heterozygote (hereafter called one-allele) and homozygote or compound heterozygote (hereafter called two-allele). The patients with two-allele were significantly younger at onset than those with one-allele. Six families harbored the complex forms of one- and two-allele in different individuals of the same family. The presence of two-allele reflected more frequent normal values of [

    Abstract Introduction: A higher levodopa dose is a risk factor for motor complications in Parkinson's disease (PD). Istradefylline (IST) is used as adjunctive treatment to levodopa in PD patients with off episodes, but its impact on levodopa dose titration remains unclear. The objective of this study was to investigate the effect of IST on levodopa dose escalation in PD patients with wearing-off.
    Methods: This was a multicenter, open-label, randomized, parallel-group controlled study (ISTRA ADJUST PD) in which PD patients experiencing wearing-off (n = 114) who were receiving levodopa 300-400 mg/day were randomized to receive IST or no IST (control). Levodopa dose was escalated according to clinical severity. The primary endpoint was cumulative additional levodopa dose, and secondary endpoints were changes in symptom rating scales, motor activity determined by a wearable device, and safety outcomes.
    Results: The cumulative additional levodopa dose throughout 37 weeks and dose increase over 36 weeks were significantly lower in the IST group than in the control group (both p < 0.0001). The Movement Disorder Society Unified Parkinson's Disease Rating Scale Part I and device-evaluated motor activities improved significantly from baseline to 36 weeks in the IST group only (all p < 0.05). Other secondary endpoints were comparable between the groups. Adverse drug reactions (ADRs) occurred in 28.8% and 13.2% of patients in the IST and control groups, respectively, with no serious ADRs in either group.
    Conclusion: IST treatment reduced levodopa dose escalation in PD patients, resulting in less cumulative levodopa use. Adjunctive IST may improve motor function more objectively than increased levodopa dose in patients with PD.
