Study design: Observational Study
Abstract: Background Continuous subcutaneous apomorphine infusion (CSAI) is a standard of care treatment in advanced Parkinson's disease (PD) to treat motor fluctuations. However, literature about its long-term data is scarce. Objective The aim of this study was to report about CSAI tolerance and discontinuation predictors in a large monocentric cohort. Methods Consecutive PD patients who had CSAI were included. CSAI duration, discontinuation rates at 3, 12, 24, 36, 48, and 60 months, demographic data, MDS-UPDRS motor score, adverse events (AEs), discontinuation reasons and predictive factors were analyzed with logistic regression. Results A total of 208 patients were included from 1999 to 2023 (51% male; age: 67.4 ± 8.3 years; PD duration: 11.2 ± 5.0 years). In the overall group, CSAI duration was 25.0 ± 32.9 months (median: 13.0, range: 0.1–260.0). Ninety-five patients (45.7%) discontinued CSAI after 12.7 ± 15.3 months (median: 8.0). Main discontinuation causes were switching to deep brain stimulation (44.2%) and low efficacy (15.8%). Sixty% of discontinuations occurred within the first year. CSAI duration was the only significant difference between ongoing CSAI (116) and discontinued patients (35.4 ± 39.7 vs. 11.1 ± 18.4 months; p < 0.001), after excluding 42 CSAI-to-DBS. About 79.8% patients had AEs, mainly hallucinations (41.3%) and nodules (24.0%). The best discontinuation predictors were CSAI duration and baseline off medication MDS-UPDRS motor score. Conclusions These results may help clinicians better select patients, anticipate and manage AEs, and predict CSAI discontinuation.
