Abstract

© 2015 Elsevier Ltd. Introduction: Continuous infusion of levodopa/carbidopa intestinal gel (LCIG) is an effective treatment for patients with advanced Parkinson Disease (PD) that cannot be further improved by oral therapy. Methods: We conducted an observational, prospective, and multicenter study to collect, in a large sample of PD treated with LCIG, long-term information about the outcome and safety of the treatment. The assessments were performed before LCIG, 1, 3, 6 months after, and ever since, every 6 months. Results: We studied 72 patients with a mean observation time of 22 months and a maximum of 48 months. During follow-up 28 patients discontinued the treatment, especially for lack of efficacy or adverse events related to the drug. We obtained a significant improvement of motor and non-motor fluctuations, mean off time and some non-motor symptoms. A significant increase in the percentage of time with dyskinesias was found in patients having less than 50% of the day with dyskinesias before LCIG. However, patients having already many dyskinesias before LCIG experienced a significant decrease of the troublesome dyskinesias, meaning that outcomes might be different depending on specific clinical characteristics. Adverse effects were in general minor but one case of intestinal perforation and one of abdominal cellulite were observed. Conclusions: We confirmed that LCIG is a very effective treatment option for advanced PD; however considering the findings that dyskinesia can increase and the potential for serious side effects, we suggest the necessity for development of guidelines that better define the profile of responders.
