- Subcutaneous apomorphine infusion (Apo) and intrajejunal levodopa infusion (IJLI) are two treatment options for patients with advanced Parkinson's disease (PD) and refractory motor complications, with varying cost of treatment. There are no multicenter studies comparing the effects of the two strategies. This open-label, prospective, observational, 6-month, multicenter study compared 43 patients on Apo (48.8% males, age 62.3 +/- 10.6 years; disease duration: 14 +/- 4.4 years; median H & Y stage 3; interquartile range [IQR]: 3-4) and 44 on IJLI (56.8% males, age 62.7 +/- 9.1 years; disease duration: 16.1 +/- 6.7 years; median H & Y stage 4; IQR, 3-4). Cohen's effect sizes (0.8 considered as large) were large with both therapies with respect to total motor, nonmotor, and quality-of-life scores. The Non-Motor Symptoms Scale (NMSS) with Apo showed moderate improvement, whereas sleep/fatigue, gastrointestinal, urinary, and sexual dimensions of the NMSS showed significantly higher improvement with IJLI. Seventy-five percent on IJLI improved in their quality-of-life and nonmotor symptoms (NMS), whereas in the Apo group, a similar proportion improved in quality of life, but 40% in NMS. Adverse effects included peritonitis with IJLI and skin nodules on Apo. Based on this open-label, nonrandomized, comparative study, we report that, in advanced Parkinson's patients, both IJLI and Apo infusion therapy appear to provide a robust improvement in motor symptoms, motor complications, quality-of-life, and some NMS. Controlled, randomized studies are required. (c) 2014 International Parkinson and Movement Disorder Society

- Introduction: The clinical diagnosis of Parkinson’s disease (PD) is based on the identification of bradykinesia and at least one additional feature among rigidity, resting tremor and postural instability. These clinical features have been estimated to appear when at least 50% of the nigral dopamine neurons and 70% of putaminal dopamine tissue contents are lost [1]. Dopaminergic imaging suggests that at least 30% of the dopamine storage capacity (measured by 18 F-DOPA uptake) and 50% of putamen dopamine transporters have been lost by the onset of contralateral limb bradykinesia and rigidity [2]. In addition to the above motor symptoms, a number of nonmotor symptoms are associated with PD. These include gastrointestinal, cardiovascular, urological and psychiatric symptoms, as well as problems with vision, pain and sleep [3]. There is general agreement that the typical motor features of PD depend on putaminal dopamine depletion. Indeed, these features respond well to dopaminergic treatments, the most effective being levodopa (l-DOPA), a dopamine precursor that can cross the blood-brain barrier. Treatment with levodopa contributes significantly to improvements in the quality of life of people with PD and increases their expected life length (reviewed in [4]). Moreover, treatment with peroral levodopa is relatively well tolerated and inexpensive [5]. Many of nonmotor symptoms may also respond to levodopa treatment [3]. Because of the above reasons, levodopa is currently considered the “gold standard” for the symptomatic treatment of PD [4, 5]. However, the response to levodopa changes with disease progression, becoming complicated by motor fluctuations and dyskinesias in a majority of patients within a few years. As will be discussed below, these motor complications can become disabling, calling for a reduction in oral levodopa dosage and/or for its replacement with advanced invasive treatments. Moreover, levodopa is poorly effective against clinical features that mainly depend on the degeneration of nondopaminergic systems. These include some nonmotor symptoms as well as motor features that occur in advanced disease stages, such as freezing of gait and falls [6]. In this chapter, we will review the history of levodopa pharmacotherapy in PD, the complications of this therapy, the options currently available to optimize oral treatment with levodopa, and recent advances in developing methods for a more continuous levodopa delivery.

- Background: Lack of a global consensus on the definition of advanced Parkinson’s disease (APD) and considerations for timing of device-aided therapies may result in heterogeneity in care. Objectives: To reach consensus among movement disorder specialists regarding key patient characteristics indicating transition to APD and guiding appropriate use of device-aided therapies in the management of PD symptoms. Methods: A Delphi-panel approach was utilized to synthesize opinions of movement disorder specialists and build consensus. Results: A panel was comprised of movement disorder specialists from 10 European countries with extensive experience of treating PD patients (mean =24.8 ± 7.2 years). Consensus on indicators of suspected APD and eligibility for device-aided therapies were based on motor symptoms, non-motor symptoms, and functional impairments. Key indicators of APD included: (i) motor—moderate troublesome motor fluctuations, ≥1 h of troublesome dyskinesia/day, ≥2 h “off” symptoms/day, and ≥5-times oral levodopa doses/day; (ii) non-motor—mild dementia, and non-transitory troublesome hallucinations; (iii) functional impairment—repeated falls despite optimal treatment, and difficulty with activities of daily living. Patients with good levodopa response, good cognition, and <70 years of age were deemed as good candidates for all three device-aided therapies. Patients with troublesome dyskinesia were considered good candidates for both levodopa-carbidopa intestinal gel and Deep Brain Stimulation (DBS). PD patients with levodopa-resistant tremor were considered good candidates for DBS. Conclusion: Identifying patients progressing to APD and suitable for device-aided therapies will enable general neurologists to assess the need for referral to movement disorder specialists and improve the quality of care and patient outcomes.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: This registry evaluated the 24-month safety and efficacy of levodopa-carbidopa intestinal gel (LCIG) treatment in advanced Parkinson's disease (PD) patients under routine clinical care. Methods: Motor fluctuations, dyskinesia, non-motor symptoms, quality of life, and safety were evaluated. Observations were fully prospective for treatment-naïve patients (60% of patients) and partially retrospective for patients with ≤12 months of pre-treatment with LCIG (40% of patients). Hours of "On" and "Off" time were assessed with a modified version of the Unified Parkinson's Disease Rating Scale part IV items 32 and 39. Results: Overall, 375 patients were enrolled by 75 movement disorder centers in 18 countries and 258 patients completed the registry. At 24 months LCIG treatment led to significant reductions from baseline in "Off" time (hours/day) (mean ± SD = -4.1 ± 3.5, P < 0.001), "On" time with dyskinesia (hours/day) (-1.1 ± 4.8, P = 0.006), Non-Motor Symptom Scale total (-16.7 ± 43.2, P < 0.001) and individual domains scores, and Parkinson's Disease Questionnaire-8 item total score (-7.1 ± 21.0, P < 0.001). Adverse events deemed to have a possible/probable causal relationship to treatment drug/device were reported in 194 (54%) patients; the most frequently reported were decreased weight (6.7%), device related infections (5.9%), device dislocations (4.8%), device issues (4.8%), and polyneuropathy (4.5%). Conclusions: LCIG treatment led to sustained improvements in motor fluctuations, non-motor symptoms particularly sleep/fatigue, mood/cognition and gastrointestinal domains, as well as quality of life in advanced PD patients over 24 months. Safety events were consistent with the established safety profile of LCIG.

Tidskriftsartikel (refereegranskat)abstract
- Background: Parkinson's disease (PD) is a chronic progressive disorder leading to increasing disability. While the symptoms and needs of patients in the early stages of their disease are well characterized, little information is available on patients in the late stage of the disease. Methods/design: The Care of Late-Stage Parkinsonism (CLaSP) study is a longitudinal, multicenter, prospective cohort study to assess the needs and provision of care for patients with late stage Parkinsonism and their carers in six European countries (UK, France, Germany, Netherlands, Portugal, Sweden). In addition, it will compare the effectiveness of different health and social care systems. Patients with Parkinsonism with Hoehn and Yahr stage ≥IV in the "On"-state or Schwab and England stage 50% or less are evaluated at baseline and three follow-up time-points. Standardised questionnaires and tests are applied for detailed clinical, neuropsychological, behavioural and health-economic assessments. A qualitative study explores the health care needs and experiences of patients and carers, and an interventional sub-study evaluates the impact of specialist recommendations on their outcomes. Discussion: Through the combined assessment of a range of quantitative measures and qualitative assessments of patients with late stage parkinsonism, this study will provide for the first time comprehensive and in-depth information on the clinical presentation, needs and health care provision in this population in Europe, and lay the foundation for improved outcomes in these patients. Trial registration: The protocol was registered at ClinicalTrials.gov as NCT02333175 on 07/01/2015.

Forskningsöversikt (refereegranskat)abstract
- Advanced Parkinson's disease (APD) is characterized by increased functional disability, caused by motor complications, the presence of axial symptoms, and emergent disease- and drug-related non-motor symptoms. One of the advanced therapies available is intrajejunal infusion of levodopa/carbidopa intestinal gel (LCIG); however, patient selection for this treatment is sometimes difficult, particularly because of overlapping indications with other alternatives. In recent years, strong evidence has supported the use of LCIG in treating motor fluctuations associated with APD, and several clinical studies provide emerging evidence for additional benefits of LCIG treatment in certain patients. This article provides an overview of the published literature on the benefits, limitations, and drawbacks of LCIG in relation to PD symptoms, the psychosocial impact of the disease, and the quality of life of patients, with the aim of determining candidates for whom treatment with LCIG would be beneficial. According to current evidence, patients with APD (defined as inability to achieve optimal control of the disease with conventional oral treatment), a relatively well-preserved cognitive-behavioral status, and good family/caregiver would count as suitable candidates for LCIG treatment. Contraindications in the opinion of the authors are severe dementia and active psychosis.

- Pain is a key unmet need and a major aspect of non-motor symptoms of Parkinson's disease (PD). No specific validated scales exist to identify and grade the various types of pain in PD. We report an international, cross-sectional, open, multicenter, one-point-in-time evaluation with retest study of the first PD-specific pain scale, the King's PD Pain Scale. Its seven domains include 14 items, each item scored by severity (0-3) multiplied by frequency (0-4), resulting in a subscore of 0 to 12, with a total possible score range from 0 to 168. One hundred seventy-eight PD patients with otherwise unexplained pain (age [mean ± SD], 64.38 ± 11.38 y [range, 29-85]; 62.92% male; duration of disease, 5.40 ± 4.93 y) and 83 nonspousal non-PD controls, matched by age (64.25 ± 11.10 y) and sex (61.45% males) were studied. No missing data were noted, and floor effect was observed in all domains. The difference between mean and median King's PD Pain Scale total score was less than 10% of the maximum observed value. Skewness was marginally high (1.48 for patients). Factor analysis showed four factors in the King's PD Pain Scale, explaining 57% of the variance (Kaiser-Mayer-Olkin, 0.73; sphericity test). Cronbach's alpha was 0.78, item-total correlation mean value 0.40, and item homogeneity 0.22. Correlation coefficients of the King's PD Pain Scale domains and total score with other pain measures were high. Correlation with the Scale for Outcomes in PD-Motor, Non-Motor Symptoms Scale total score, and quality of life measures was high. The King's PD Pain Scale seems to be a reliable and valid scale for grade rating of various types of pain in PD. © 2015 International Parkinson and Movement Disorder Society.

- Objective: Real-life observational report of clinical efficacy of bilateral subthalamic stimulation (STN-DBS), apomorphine (APO), and intrajejunal levodopa infusion (IJLI) on quality of life, motor, and nonmotor symptoms (NMS) in Parkinson's disease (PD). Methods: In this prospective, multicenter, international, real-life cohort observation study of 173 PD patients undergoing STN-DBS (n = 101), IJLI (n = 33), or APO (n = 39) were followed-up using PDQuestionnaire-8, NMSScale (NMSS), Unified PD Rating Scale (UPDRS)-III, UPDRS-IV, and levodopa equivalent daily dose (LEDD) before and 6 months after intervention. Outcome changes were analyzed with Wilcoxon signed-rank or paired t test when parametric tests were applicable. Multiple comparisons were corrected (multiple treatments/scales). Effect strengths were quantified with relative changes, effect size, and number needed to treat. Analyses were computed before and after propensity score matching, balancing demographic and clinical characteristics. Results: In all groups, PDQuestionnaire-8, UPDRS-IV, and NMSS total scores improved significantly at follow-up. Levodopa equivalent daily dose was significantly reduced after STN-DBS. Explorative NMSS domain analyses resulted in distinct profiles: STN-DBS improved urinary/sexual functions, mood/cognition, sleep/fatigue, and the miscellaneous domain. IJLI improved the 3 latter domains and gastrointestinal symptoms. APO improved mood/cognition, perceptual problems/hallucinations, attention/memory, and the miscellaneous domain. Overall, STN-DBS and IJLI seemed favorable for NMSS total score, and APO favorable for neuropsychological/neuropsychiatric NMS and PDQuestionnaire-8 outcome. Conclusions: This is the first comparison of quality of life, nonmotor. and motor outcomes in PD patients undergoing STN-DBS, IJLI, and APO in a real-life cohort. Distinct effect profiles were identified for each treatment option. Our results highlight the importance of holistic nonmotor and motor symptoms assessments to personalize treatment choices.

- BACKGROUND: Parkinson's disease (PD) is a progressive neurodegenerative condition that is expected to double in prevalence due to demographic shifts. Value-based healthcare is a proposed strategy to improve outcomes and decrease costs. To move towards an actual value-based health care system, condition-specific outcomes that are meaningful to patients are essential.OBJECTIVE: Propose a global consensus standard set of outcome measures for PD.METHODS: Established methods for outcome measure development were applied, as outlined and used previously by the International Consortium for Health Outcomes Measurement (ICHOM). An international group, representing both patients and experts from the fields of neurology, psychiatry, nursing, and existing outcome measurement efforts, was convened. The group participated in six teleconferences over a six-month period, reviewed existing data and practices, and ultimately proposed a standard set of measures by which patients should be tracked, and how often data should be collected.RESULTS: The standard set applies to all cases of idiopathic PD, and includes assessments of motor and non-motor symptoms, ability to work, PD-related health status, and hospital admissions. Baseline demographic and clinical variables are included to enable case mix adjustment.CONCLUSIONS: The Standard Set is now ready for use and pilot testing in the clinical setting. Ultimately, we believe that using the set of outcomes proposed here will allow clinicians and scientists across the world to document, report, and compare PD-related outcomes in a standardized fashion. Such international benchmarks will improve our understanding of the disease course and allow for identification of 'best practices', ultimately leading to better informed treatment decisions.
