Objective: To report the use of levodopa-carbidopa intestinal gel (LCIG) as an additional therapy for the treatment of motor fluctuations in a patient with advanced idiopathic Parkinson’s disease (PD) on deep brain stimulation (DBS).
Background: LCIG and DBS have been established treatment modalities with proven efficacy for advanced PD (1). However, there is a paucity of data in the literature regarding their use in combination (2). While clinical deterioration had been reported as the main reason for using both in a case report (3), we highlight technical barriers during the COVID-19 era as a substantial drive.
Method: Our patient was a 66-year-old gentleman with idiopathic PD for nine years. That was successfully treated with unilateral DBS of the subthalamic nucleus. Due to the imposed COVID-19 travel restriction, routine replacements of impulse generators were not accessible in due time. Besides, with re-emerging of motor fluctuations and gait difficulties, the need had been identified for another more accessible add-on therapy at our center. After proper assessment, a PEG-J tube was inserted, LCIG infusion started, and the clinical response was measured pre and post LCIG.
Results: By combining both therapies, the patient instantly regained control of his motor fluctuations and a recorded sustained improvement in his gait and balance after eight months of follow-up. This was achieved by less than expected inputs of both devices.
Conclusion: Combining two different device-assisted therapies for advanced PD could be considered a promising choice. Large-scale-controlled studies are needed to fill the gaps in knowledge.
