Abstract
The COVID-19 outbreak has had a dramatic impact on the healthcare system due to the rapid, worldwide spread of the virus, highlighting several considerations on the best management of infected patients and also potential risks and prognostic factors in patients with pre-existing chronic diseases exposed to the virus. Neurodegenerative disorders are known to be chronic, disabling diseases that imply a higher vulnerability to infections, and for this reason, it has been suggested that SARS-CoV-2 infection may have a worse course in these patients. In the present study, we report our experience with 12 patients affected by Parkinson's disease (PD) who became infected with SARS-Cov-2 due to a COVID-19 outbreak in a care residency, and thus hospitalised in our COVID hospital. Most of the PD patients had a long disease duration and multiple comorbidities even though SARS-CoV-2 manifestations were mild, and none required intensive care. Despite lung conditions, most of our PD patients had mild symptoms: 7 patients were clinically asymptomatic (58.3%); 3 patients had fever, cough, and myalgia (25%) and 2 patients had dyspnoea (16%) that needed high-flow oxygen therapy. Few complications related to PD were seen. All patients were discharged after a mean hospitalisation period of 30 days. Mortality rate during hospitalisation was zero. Our findings suggest that SARS-CoV-2 infection does not have a poor prognosis in patients with PD. More extensive data and evaluations, however, are needed to confirm our data, and caution is warranted.
