Close relationships in Parkinson´s disease patients with device-aided therapy

OBJECTIVES

Deep brain stimulation, continuous subcutaneous apomorphine infusion, and levodopa-carbidopa intestinal gel infusion, together called device-aided therapies (DAT), are introduced when oral and transdermal pharmacotherapy are not enough for a satisfactory control of Parkinson's disease (PD) symptoms. Solid relationships are central to an individual's well-being, but the impact of close relationships in advanced PD remains underexplored. The aim of this study was to investigate the development of close relationships between PD patients and their partners following the initiation of DAT and to examine the relationship structures in these relationships.

MATERIALS AND METHODS

This was a retrospective quantitative multicenter pilot study wherein 41 couples, patients with advanced PD and their partners, retrospectively rated their relationship satisfaction before the start of DAT, after one year of DAT and at the time of the interview. The couples also answered the Experiences in Close Relationships-Questionnaire of Relational Structures (ECR-RS).

RESULTS

Partners more often report changes in relationship satisfaction than patients between baseline and both 1 year after start of DAT (p = .049) and last evaluation (p = .041). The ECR-RS data reported significantly higher avoidance score for partners (p = .005) and significantly higher anxiety score for patients (p = .024).

CONCLUSIONS

The close relationship wherein one part has PD and receives DAT has a high risk of being unequal. Prospective studies are needed for further clarification of the interplay between advanced PD, DAT, and close relationships, this in order to improve pre- and postinterventional support for PD patients receiving DAT, as well as their partners.

Levodopa-entacapone-carbidopa intestinal gel: Data from the Swedish national registry for Parkinson's disease

BACKGROUND

Levodopa-entacapone-carbidopa intestinal gel (LECIG) was introduced on the Swedish market in 2019. The therapy is aimed at patients with Parkinson's disease (PD) with fluctuations and dyskinesias. Long-term efficacy and safety data are lacking.

OBJECTIVE

To investigate the efficacy, tolerability, and safety of LECIG in regular clinical practice for Parkinson's disease in Sweden.

METHODS

Real-world data were collected from the Swedish registry for Parkinson's disease (ParkReg) for all patients reported to receive LECIG during the period from 2019 until 31 August 2022.

RESULTS

A total of 150 patients were identified. Sixty-one (41%) of 150 patients were females. At the start of treatment, the median age was 73 years (range: 43-86). The median duration since motor symptoms onset was 17 years (IQR: 9). Fifty (33%) of 150 patients switched from another device-assisted therapy, mostly LCIG (39 patients). Reported complications were mainly related to PEG-J tube and stoma (30%). Twenty (13.3%) of 150 patients discontinued LECIG and 11 (7.3%) patients died while on LECIG. The Parkinson KinetiGraph scores for bradykinesia, dyskinesia, fluctuations, tremor, and immobility for 53 patients during LECIG showed good therapy control. The median (IQR) p-Hcy during LECIG was 12 (4.6) μmol/L (n = 44). The median (IQR) PDQ-8 summary index during LECIG was 31 (17) (n = 52). The median (IQR) EQ5D during LECIG was 0.62 (0.32) (n = 41).

CONCLUSIONS

Data from ParkReg covering 150 patients over 3 years show LECIG to be an effective and safe device-aided therapy for advanced PD. However, the long-term efficacy and tolerability of LECIG need to be further investigated.
