RESUMO
BACKGROUND: Levodopa-carbidopa intestinal gel (LCIG) therapy has been shown to be a safe and effective treatment for advanced Parkinson's disease (PD). Limited data are available regarding long-term benefits and complications in Canada. Objective of the study was to review long-term experience and clinical outcomes in PD patients with LCIG therapy over 11 years in a multidisciplinary University clinic setting. METHODS: Chart review was done on PD patients with LCIG from 2011 to 2022. Data collected: dosing, UPDRS-III motor scores, OFF times, hours with dyskinesias, MoCA, complications, discontinuation reasons, and nursing time requirements. RESULTS: Thirty-three patients received LCIG therapy with a mean follow-up of 3.25±2.09 years. UPDRS-III scores showed reduction of 15% from baseline (mean 35.9) up to 4 years (mean 30.4). Daily OFF time improved from baseline (mean 7.1 ± 3.13 hours) up to 5 years (mean 3.3 ± 2.31 hours; -53.5%; p < 0.048), and dyskinesias remained stable. Nursing time averaged 22 hours per patient per year after PEG-J insertion and titration. Most common complications were PEG-J tube dislodgement and stoma site infection (0-3zero to three events/patient/year). Serious side effects were seen in four (12%) patients resulting in hospitalization and/or death. Nine patients (27.2%) discontinued the treatment due to lack of improved efficacy over oral therapy or development of dementia and 10 (30%) died of causes unrelated to LCIG infusion. CONCLUSION: Patients on LCIG showed improved motor function over 5-year follow-up. Serious complications were uncommon. Dedicated nursing time is required by LCIG-trained nurses in a multidisciplinary setting for optimum management.
