BACKGROUND: Levodopa-carbidopa intestinal gel (LCIG) improves motor and non-motor symptoms in patients with advanced Parkinson's disease (aPD). OBJECTIVE: To present the final 36-month efficacy and safety results from DUOGLOBE (DUOdopa/Duopa in Patients with Advanced Parkinson's Disease - a GLobal OBservational Study Evaluating Long-Term Effectiveness; NCT02611713). METHODS: DUOGLOBE was an international, prospective, long-term, real-world, observational study of patients with aPD initiating LCIG in routine clinical care...

BACKGROUND: Tablet formulations of Parkinson's disease (PD) medications may become ineffective at managing motor fluctuations in advanced PD. The liquid formulation, levodopa carbidopa ascorbic acid solution, or LCAS, is an effective and inexpensive treatment for motor fluctuations however it remains underutilized. OBJECTIVE: We compared the efficacy of LCAS with tablet formulations and Duodopa jejunal infusion through routine inpatient management using hourly functional status measures, the Timed Up and Go Test (TUG)...

The aim of the study was to point out the contribution of new invasive therapeutic procedures in the treatment of advanced stages of Parkinson's disease (PD) in comparison with classical oral pharmacotherapy. Data originated from a group of 43 patients with PD, 39% (17) with classic treatment, 23% (10) with intestinal gel of methyl ester levodopa (Duodopa), 19% (8) of patients were using subcutaneous delivery of apomorphine (APO) and the same quantity of patients had undergone deep brain stimulation (DBS). Majority of patients had advanced stages of PD, stage 4, by standards of Hoehn and Yahr scale (Hoehn and Yahr, 1967)...

BACKGROUND: The role of the gut-brain axis has been recently highlighted as a major contributor to Parkinson's disease (PD) physiopathology, with numerous studies investigating bidirectional transmission of pathological protein aggregates, such as α-synuclein (αSyn). However, the extent and the characteristics of pathology in the enteric nervous system have not been fully investigated. OBJECTIVE: We characterized αSyn alterations and glial responses in duodenum biopsies of patients with PD by employing topography-specific sampling and conformation-specific αSyn antibodies...

INTRODUCTION: Carbidopa/levodopa enteral suspension (CLES) previously demonstrated reduction in total daily OFF from baseline by over 4 hours in advanced Parkinson's disease patients across 54 weeks. Evidence on CLES's long-term effectiveness on patterns of motor-symptom control throughout the day remains limited. METHODS: We present post-hoc analyses of a large, open-label study of CLES monotherapy (N = 289). Diary data recorded patients' motor states at 30-minute intervals over 3 days at baseline and weeks 4, 12, 24, 36, and 54...

The clinical impact of therapeutic interventions in Parkinson's disease is often measured as a reduction in OFF-time when the beneficial effects of the standard-of-care L-DOPA formulations wanes off. We investigated the pharmacodynamic interactions of augmentation therapy to standard-of-care using a quantitative systems pharmacology (QSP) model of the basal ganglia motor circuit, essentially a computer model of neuronal firing in the different subregions with anatomically informed connectivity, cell-specific expression of 17 different G-protein coupled receptors and corresponding coupling to voltage-gated ion channel effector proteins based on experimentally observed intracellular signaling...

We report a case of small bowel occlusion due to the formation of a bezoar around a knot at the distal end a gastro-jejunal catheter used for continuous levodopa/carbidopa intestinal gel (LCIG) in a patient with advanced Parkinson's disease. The patient presented with a history of abdominal pain and vomiting starting 24 h before admission and frequent failure of his LCIG device for the past week. Small bowel occlusion along with a knot formation on the distal catheter was confirmed by contrast enhanced CT scan...

BACKGROUND: Levodopa-carbidopa intestinal gel (LCIG) is an established treatment for improving motor and some non-motor symptoms (NMS) in patients with advanced Parkinson's disease (PD). Prospective long-term data in routine clinical practice are limited. OBJECTIVE: Assess LCIG effectiveness and safety in patients with advanced PD after 12 months during real-world routine clinical practice. METHODS: Duodopa/Duopa in patients with advanced Parkinson's disease-a global observational study evaluating long-term effectiveness (DUOGLOBE) (NCT02611713) is an ongoing, prospective, multinational, observational study of LCIG-naïve patients treated as part of routine clinical practice; 3 years of follow-up are planned...

Advanced Parkinson's disease is inconsistently defined, and evidence is lacking in relation to device-aided therapies. To update existing reviews of intrajejunal infusion of levodopa/carbidopa (LCIG), we performed a literature search for relevant articles (to November 3, 2020) using PubMed supplemented by hand searching. Retrieved articles were categorized by relevance to identified research questions, including motor complications and symptoms; nonmotor symptoms; functioning, quality of life, and caregiver burden; optimal timing of treatment initiation and administration duration; discontinuation; and complications...

INTRODUCTION: A significant proportion of patients with Parkinson's disease (PD) display a set of impulsive-compulsive behaviors at some point during the course of illness. These behaviors range from the so-called behavioral addictions to dopamine dysregulation syndrome, punding and hoarding disorders. These behaviors have been consistently linked to the use of dopaminergic medications used to treat PD motor symptoms (dopamine agonists, levodopa, and other agents) and less consistently to neuromodulation techniques such as deep brain stimulation (DBS)...

BACKGROUND AND PURPOSE: Recent data suggest that imbalances in the composition of the gut microbiota (GM) could exacerbate the progression of Parkinson disease (PD). The effects of levodopa (LD) have been poorly assessed, and those of LD-carbidopa intestinal gel (LCIG) have not been evaluated so far. The aim of this study was to identify the effect of LD and LCIG, in particular, on the GM and metabolome. METHODS: Fecal DNA samples from 107 patients with a clinical diagnosis of PD were analyzed by next-generation sequencing of the V3 and V4 regions of the 16S rRNA gene...

Aim: A Delphi expert consensus panel proposed that fulfilling ≥1 of the '5-2-1 criteria' (≥five-times daily oral levodopa use, ≥two daily hours with 'Off' symptoms or ≥one daily hour with troublesome dyskinesia) suggests advanced Parkinson's disease (PD). Patients & methods: DUOdopa/Duopa in Patients with Advanced PD - a GLobal OBservational Study Evaluating Long-Term Effectiveness (DUOGLOBE) - is a single-arm, postmarketing, observational, long-term effectiveness study of levodopa-carbidopa intestinal gel (LCIG) for advanced PD...

An enteral suspension (ES)/intestinal gel formulation of levodopa/carbidopa (hereafter referred to as levodopa/carbidopa ES) [Duodopa® (EU); Duopa™ (USA)] has been developed to overcome the fluctuating plasma levodopa concentrations associated with oral levodopa/carbidopa formulations. In various countries, including those of the EU (under the Mutual Recognition Procedure), it is approved for the treatment of advanced levodopa-responsive Parkinson's disease (PD) with severe motor fluctuations and hyperkinesia or dyskinesia when available combinations of Parkinson medicinal products have not given satisfactory results...

AIMS: To carry out a cost-utility analysis comparing the cost-effectiveness of levodopa carbidopa intestinal gel (LCIG) with standard of care (SOC) in patients with advanced Parkinson's Disease (aPD) unsuitable for apomorphine or deep brain stimulation (DBS). LCIG is the only treatment option in this small, but clinically important, population. METHODS: A Markov model with 25 disease states based on disease stage and off-time status plus death. Patients enter the model with aPD spending >50% of their waking day in the off-state...

Continuous duodenal infusion of levodopa/carbidopa intestinal gel (LCIG) is an established treatment to control motor fluctuations in Parkinson's disease. Duodenal infusion allows a steady absorption of the drug in the small bowel, reducing plasmatic fluctuations of levodopa. Some complications may occur during the treatment, often related to intrajejunal percutaneous endoscopic gastrostomy (PEG-J). We report a case of duodenal ulcer associated with a phytobezoar involving the end of jejunal probe, in a patient who underwent PEG-J for LCIG infusion...

The gold standard of treatment in Parkinson's disease (PD) is levodopa/carbidopa whose long-term use induces motor and non-motor fluctuations and dyskinesias. Continuous infusion of intrajejunal levodopa/carbidopa intestinal gel (Duodopa® ) reduces motor and non-motor symptoms and dyskinesias, and improves the quality of life of patients. The aim of this open observational prospective study was to evaluate the impact of Duodopa® on conditions of PD patients and caregivers, and their quality of life...
