IntroductionThe GREENFIELD observational study assessed the effect of levodopa/carbidopa intestinal gel (LCIG) on motor and non-motor symptoms, and the related impact on patient quality of life and caregiver burden up to 8 years.MethodsFinal results of a large Italian cohort of patients who started LCIG in routine care between 2007 and 2014 are presented. Comparison between baseline (before LCIG) and follow-up visits on yearly basis (visit 2/3) is reported. Primary endpoint was Unified Parkinson's Disease Rating Scale (UPDRS-IV) Item 39; secondary endpoints were UPDRS I and II, dyskinesia items, PD Quality of Life Questionnaire-39, Parkinson's Disease Sleep Scale-2, Gait and Falls Questionnaire, Questionnaire on Impulsive Disorders, and Relative Stress Scale.ResultsOverall, 145 patients from 14 centers were assessed with a mean time since LCIG start of 2.8 ± 1.7 years at visit 2. The mean UPDRS-IV item 39 score showed significant reductions compared to baseline (mean score 2.0 ± 0.81) at visit 2 (mean score 0.9 ± 0.69; - 55%; p ConclusionsThe results of this study support the long-term efficacy of LCIG on PD symptoms as well as on activities of daily living. The adverse events were consistent with the established LCIG safety profile.
