Levodopa-Carbidopa-Entacapone Intestinal Gel for Advanced Parkinson's Disease-Results from a Monocentric Study...

Background: Parkinson's disease (PD) in advanced stages becomes, over time, a significant challenge, as oral medication becomes ineffective, and it may become necessary to switch to device-assisted therapy (DAT). This should be personalized according to the stage of the disease, the cognitive status of the patients, the association of frailty syndrome or other comorbidities, the support in care from the family, etc. Levodopa-carbidopa-entacapone intestinal gel can significantly improve the status of patients, provided that they are correctly selected for this type of treatment. Materials and Methods: We conducted a single-center prospective study including 20 advanced PD patients, who received a levodopa-carbidopa-entacapone gel through an intestinal pump, within the Parkinson's Disease Multimodal Treatment Center of the Neurology Clinic of the "St. Ap. Andrew" County Emergency Clinical Hospital in Galați, Romania. The evaluations were performed at baseline (T0), after intestinal pump insertion (T1), and 6 months after the procedure (T2). Results: In the study group, the administration of the levodopa-carbidopa-entacapone intestinal gel, using the device for intestinal administration, had significant benefits, especially for motor symptoms. The periods of off, no-on, freezing, sudden-off, as well as dyskinesia and morning akinesia, were significantly reduced. Among the non-motor symptoms, depression and sleep disorders improved, with no changes in cognitive status and psychotic disorders. Conclusions: Adding new data for the use of device-assisted therapy in advanced PD, our study also highlights the need to further research this challenging patient profile.
