Chinese Medicine Theory

Nonmotor symptoms (NMS) of Parkinson’s disease (PD) have devastating impacts on both patients and their caregivers. Jiawei-Liujunzi Tang (JLT) has been used to treat some NMS of PD based on the Chinese medicine theory since Qing dynasty. Here we report a double-blind, randomized, placebo-controlled, add-on clinical trial aiming at evaluating the efficacy and safety of the JLT in treating NMS in PD patients. We randomly assigned 111 patients with idiopathic PD to receive either JLT or placebo for 32 weeks. Outcome measures were baseline to week 32 changes in Movement Disorder Society-Sponsored Revision of Unified PD Rating Scale (MDS-UPDRS) Parts I–IV and in NMS assessment scale for PD (NMSS). We observed improvements in the NMSS total score (p=0.019), mood/cognition (p=0.005), and reduction in hallucinations (p=0.024). In addition, post hoc analysis showed a significant reduction in constipation (p<0.001). However, there was no evidence of improvement in MDS-UPDRS Part I total score (p=0.216) at week 32. Adverse events (AEs) were mild and comparable between the two groups. In conclusion, long-term administration of JLT is well tolerated and shows significant benefits in improving NMS including mood, cognition, and constipation.

Abstract BackgroundParkinson’s Disease (PD) patients have lower niacin levels compared to their spouses. The main objective was to study low-dose daily niacin supplementation versus placebo on motor symptoms in Parkinson’s disease subjects.MethodsA randomized, placebo-controlled, double-blind, single-center clinical trial in Parkinson’s disease patients was performed in Augusta, GA, between September 2016 to September 2019. Randomized participants were 47 PD patients who received either low-dose niacin (N = 21 ) or placebo (N = 26) for the first six months (mean age 68.4 SD, 8.7; mean duration of disease 5.8 SD 4.9; H&Y scores between 0.5 to 4; 64% subjects were Veterans). The Veterans Affairs Pharmacy generated the randomized sequence. After the double-blind phase, all participants received open-label niacin for the next six months. All patients were evaluated at baseline, six months, and one year of treatment. The main outcome measure was the Unified Parkinson’s Disease Rating Scale III (UPDRS III) scores. Secondary outcome measures were depression, sleep quality, mental flexibility and cognition, and physical fatigue.Results39 subjects were analyzed with low-dose niacin (N = 18) and placebo (N = 21) for the completion of the first six months (randomized, double-blind), and 31 subjects were analyzed for the completion of the next six months (open-label) with low-dose niacin (N = 14) and placebo (N = 17). Niacin treatment was not tolerated by two subjects. The baseline mean UPDRS III score was 21.3 ± 15.8 for the niacin group and 22.4 ± 11.8 for placebo. The change with six months of placebo was 0.05 [95% CI, -2.4 to 2.32], and niacin was 1.06 [95% CI, -3.68 to 1.57]. From six to twelve months, the average UPDRS III score decreased for the placebo group by 4.58 [95% CI, -0.85 to 8.30] and the niacin group by 4.63 [95% CI, 1.42 to 7.83]. Eight subjects withdrew from the study before the 6-month time point and eight more before the one-year time point due to voluntary discontinuation, flushing, or inability to continue (SARS-CoV-2 shut-down).ConclusionLow-dose niacin supplementation may be helpful as an adjunct therapy in improving motor function in PD.Trial registrationClinicaltrials.gov, NCT03462680.

Dyskinesia refers to any involuntary movement, such as chorea, dystonia, ballism that affect any part of the body. Levodopa-induced dyskinesia is a neurological disorder that afflicts many patients with Parkinson disease usually 5 years after the onset of levodopa therapy and can cause severe disability. The pathophysiology of this dyskinesia is complex and not fully understood. However, the association between vitamin D and Parkinson disease is interesting. The present study was conducted to evaluate the effect of vitamin D on levodopa induced dyskinesia in patients with Parkinson’s disease .In this Double blind clinical trial, 120 patients with PD divided into two groups randomly, vitamin D and placebo group. A dose of 1000 IU/d was selected, Demographic information is registered. In the first visit, three variables have been measured which were the duration, severity of dyskinesia and unified Parkinson’s disease rating scale (UPDRS). These variables were measured again after 3 months and the data was analyzed using SPSS 22. There are no differences between two groups after 3 months. This study revealed, vitamin D has no effects on improvement of levodopa induced dyskinesia.

A six-month double-blind, placebo-controlled randomized study was conducted to ascertain whether low-dose daily niacin supplementation would improve motor symptoms in Parkinson’s disease (PD) patients. A total of 47 PD patients were assigned to receive low-dose niacin or a placebo. At the end of the double-blind phase, all participants received open-label niacin for the next six months. All patients were evaluated at baseline, after six months, and after one year of treatment. The primary outcome measure was the Unified Parkinson’s Disease Rating Scale III (UPDRS III) scores. Secondary outcome measures were depression, sleep quality, mental flexibility and cognition, and physical fatigue. Niacin treatment was well-tolerated by forty-five subjects. The mean [95% CI] change in UPDRS III scores at six months of placebo was −0.05 [95% CI, −2.4 to 2.32], and niacin was −1.06 [95% CI, −3.68 to 1.57]. From six to twelve months when both groups received open-label niacin supplementation, the average UPDRS III scores significantly decreased for the placebo group by 4.58 [95% CI, −0.85 to 8.30] and the niacin group by 4.63 [95% CI, 1.42 to 7.83] points. Low-dose niacin supplementation is a well-tolerated adjunct therapy and may improve motor function in PD when taken over a longer period.

Immunosuppressant Medication

IntroductionThe immune system is implicated in the aetiology and progression of Parkinson’s disease (PD). Inflammation and immune activation occur both in the brain and in the periphery, and a proinflammatory cytokine profile is associated with more rapid clinical progression. Furthermore, the risk of developing PD is related to genetic variation in immune-related genes and reduced by the use of immunosuppressant medication. We are therefore conducting a ‘proof of concept’ trial of azathioprine, an immunosuppressant medication, to investigate whether suppressing the peripheral immune system has a disease-modifying effect in PD.Methods and analysisAZA-PD is a phase II randomised placebo-controlled double-blind trial in early PD. Sixty participants, with clinical markers indicating an elevated risk of disease progression and no inflammatory or immune comorbidity, will be treated (azathioprine:placebo, 1:1) for 12 months, with a further 6-month follow-up. The primary outcome is the change in the Movement Disorder Society-Unified Parkinson’s Disease Rating Scale gait/axial score in the OFF state over the 12-month treatment period. Exploratory outcomes include additional measures of motor and cognitive function, non-motor symptoms and quality of life. In addition, peripheral and central immune markers will be investigated through analysis of blood, cerebrospinal fluid and PK-11195 positron emission tomography imaging.Ethics and disseminationThe study was approved by the London-Westminster research ethics committee (reference 19/LO/1705) and has been accepted by the Medicines and Healthcare products Regulatory Agency (MHRA) for a clinical trials authorisation (reference CTA 12854/0248/001–0001). In addition, approval has been granted from the Administration of Radioactive Substances Advisory Committee. The results of this trial will be disseminated through publication in scientific journals and presentation at national and international conferences, and a lay summary will be available on our website.Trial registration numbersISRCTN14616801 and EudraCT- 2018-003089-14.

Background. Exercise is increasingly becoming recognized as an important adjunct to medications in the clinical management of Parkinson’s disease (PD). Boxing and sensory exercise have shown immediate benefits, but whether they continue beyond program completion is unknown. This study aimed to investigate the effects of boxing and sensory training on motor symptoms of PD, and whether these benefits remain upon completion of the intervention. Methods. In this 20-week double-blinded randomized controlled trial, 40 participants with idiopathic PD were randomized into 2 treatment groups, (n = 20) boxing or (n = 20) sensory exercise. Participants completed 10 weeks of intervention. Motor symptoms were assessed at (week 0, 10, and 20) using the Unified Parkinson’s Disease Rating Scale (UPDRS-III). Data were analyzed using SPSS, and repeated-measures ANOVA was conducted. Results. A significant interaction effect between groups and time were observed F(1, 39) = 4.566, P = .036, where the sensory group improved in comparison to the boxing group. Post hoc analysis revealed that in comparison to boxing, the effects of exercise did not wear off at washout (week 20) P < .006. Conclusion. Future rehabilitation research should incorporate similar measures to explore whether effects of exercise wear off post intervention.
