Nocturnal continuous subcutaneous infusion of apomorphine in advanced Parkinson’s disease: a series of 37 cases
Aim. Multiple factors can cause sleep disturbances in Parkinson’s disease. The quality of sleep and therefore of life is usually improved with continuous dopaminergic stimulation therapies, such as continuous subcutaneous infusion of apomorphine.
Patients and methods. We present an observational retrospective study of patients at our centre with advanced Parkinson’s disease, treated with continuous infusion of apomorphine, with treatment extended to nights, between 2011 and 2022. We collected data from 37 patients, and evaluated the indication for nocturnal treatment, efficacy, safety and reasons for withdrawal.
Results. Fifty percent of patients began nocturnal treatment for motor complications, 19% for non-motor complications and 31% for both. The most common non-motor symptoms were sleep fragmentation and disturbances, neuropathic pain, psychiatric symptoms and intense nocturia. Twenty of the 37 patients (54%) were continuing treatment at the end of the study follow-up, 16 (43%) discontinued the infusion, and one (3%) was lost to follow-up. The adverse reactions that led to termination of the infusion were severe nodules (two), dopaminergic psychosis (one) and a positive Coombs test with/without anaemia (one). Four patients terminated the nocturnal infusions while continuing the daytime infusions due to suboptimal adaptation to the device. Patients whose symptoms improved without any significant adverse effects continued the treatment.
Conclusions. Continuous infusion of apomorphine during the night was an effective and safe treatment in our series.
