Impact of the COVID-19 pandemic on clinical autonomic practice in Europe A survey of the European Academy of Neurology (EAN) and the European Federation of Autonomic Societies (EFAS).

OBJECTIVE: To investigate the impact of the coronavirus-disease-2019 (COVID-19) pandemic on European clinical autonomic practice. METHODS: Eighty-four neurology-driven or interdisciplinary autonomic centers in 22 European countries were invited to fill in a web-based survey between September and November 2021. RESULTS: Forty-six centers completed the survey (55%). During the first pandemic year, the number of performed tilt-table tests, autonomic outpatient and inpatient visits decreased respectively by 50%, 45% and 53%, and every-third center reported major adverse events due to postponed examinations or visits. The most frequent newly-diagnosed or worsened cardiovascular autonomic disorders after COVID-19 infection included postural orthostatic tachycardia syndrome (POTS), orthostatic hypotension, and recurrent vasovagal syncope, deemed likely related to the infection by ≥50% of the responders. Forty-seven percent of the responders also reported about people with new-onset of orthostatic intolerance, but negative tilt-table findings, and 16% about people with psychogenic pseudosyncope after COVID-19. Most patients were treated non-pharmacologically and symptomatic recovery at follow-up was observed in ≥45% of cases. By contrast, low frequencies of newly-diagnosed cardiovascular autonomic disorders following COVID-19 vaccination were reported, most frequently POTS and recurrent vasovagal syncope, and most of the responders judged a causal association unlikely. Non-pharmacological measures were the preferred treatment choice, with 50-100% recovery rates at follow-up. CONCLUSIONS: Cardiovascular autonomic disorders may develop or worsen following a COVID-19 infection, while the association with COVID-19 vaccines remains controversial. Despite the severe pandemic impact on European clinical autonomic practice, a specialized diagnostic work-up was pivotal to identify non-autonomic disorders in people with post-COVID-19 orthostatic complaints.

Risk of SARS-CoV-2 infection, hospitalization and death for COVID-19 in people with Parkinson's disease or parkinsonism over a 15-month period: a cohort study.

BACKGROUND: The patterns of long term risk of SARS-CoV-2 infection, hospitalization for COVID-19 and related death are uncertain in people with Parkinson's disease (PD) or parkinsonism (PS). The aim of the study was to quantify these risks compared to a control population cohort, during the period March 2020-May 2021, in Bologna, northern Italy. METHOD: ParkLink Bologna cohort (759 PD; 192 PS) and controls (9,226) anonymously matched (ratio 1:10) for sex, age, district, comorbidity were included. Data were analysed in the whole period and in the two different pandemic waves (March-May 2020 and October 2020-May 2021). RESULTS: Adjusted hazard ratio of SARS-CoV-2 infection was 1.3 (95% CI 1.04-1.7) in PD and 1.9 (1.3-2.8) in PS compared to the controls. The trend was detected in both the pandemic waves. Adjusted hazard ratio of hospitalization for COVID-19 was 1.1 (95% CI 0.8-1.7) in PD and 1.8 (95% CI 0.97-3.1) in PS. A higher risk of hospital admission was detected in PS only in the first wave. The 30-day mortality risk after hospitalization was higher (p=0.048) in PS (58%) than in PD (19%) and controls (26%). CONCLUSIONS: Compared with controls, after adjustment for key covariates, people with PD and PS showed a higher risk of SARS-CoV-2 infection throughout the first 15 months of the pandemic. COVID-19 hospitalization risk was increased only in people with PS and only during the first wave. This group of patients was burdened by a very high risk of death after infection and hospitalization.

The Indirect Impact of COVID-19 on Major Clinical Outcomes of People With Parkinson's Disease or Parkinsonism: A Cohort Study.

Background: The indirect impact of the COVID-19 epidemic on major clinical outcomes of people with Parkinson's disease (PD) or other parkinsonism is unknown. Objectives: The study aimed to (1) describe changes in healthcare services during the first epidemic bout in people with PD or parkinsonism; (2) compare the occurrence of hospitalization for any PD-related major clinical outcomes in 2020 with 2019; (3) investigate the factors, including changes in healthcare services, associated with major clinical outcomes and death. Methods: All healthcare services of the province of Bologna and major clinical outcomes were assessed through a record linkage study (ParkLink Bologna) using clinical data and health databases. Same analyses were performed in a random cohort of controls matched for age, sex, district of residence, and comorbidities with the ParkLink cohort (ratio of 1:10). Results: A cohort of subjects with PD (759) or other parkinsonism (192) was included together with a cohort of controls (9,226). All indicators of healthcare services dropped at least below 50% during the lockdown period in all cohorts, mostly impacting physiotherapy in people with PD (-93%, 95% CI 88-96%). In 2020, compared to 2019, a three-fold risk of major injuries (RR 3.0, 95% CI 1.5-6.2) and infections (RR 3.3, 95% CI 1.5-7.2), excluding COVID-19, was observed only in people with PD, and neither in people with parkinsonism nor in controls. Decreased physiotherapy was associated with the occurrence of at least one major clinical outcome (OR 3.3, 95% CI 1.1-9.8) in people with PD. Experiencing at least one major clinical outcome was the strongest risk factor for death (OR 30.4, 95% CI 11.1-83.4) in people with PD. Conclusions: During the first COVID-19 epidemic peak, healthcare services were drastically reduced in a province of northern Italy, regardless of the disease condition. However, compared to 2019, in 2020, only people with PD had a higher risk of major clinical outcomes, that were associated with higher mortality. Strategies to maintain physical activity in people with PD should be implemented in possible future health emergencies.

Risk of Hospitalization and Death for COVID-19 in People with Parkinson's Disease or Parkinsonism.

BACKGROUND: The risk of COVID-19 and related death in people with Parkinson's disease or parkinsonism is uncertain. The aim of the study was to assess the risk of hospitalization for COVID-19 and death in a cohort of patients with Parkinson's disease or parkinsonism compared with a control population cohort, during the epidemic bout (March-May 2020) in Bologna, northern Italy. METHODS: Participants of the ParkLink study with the clinical diagnosis of Parkinson's disease or parkinsonism and people anonymously matched (ratio 1:10) for sex, age, district, and Charlson Index were included. The hospital admission rate for COVID-19 (February 26-May 31, 2020) and the death rate for any cause were the outcomes of interest. RESULTS: The ParkLink cohort included 696 subjects with Parkinson's disease and 184 with parkinsonism, and the control cohort had 8590 subjects. The 3-month hospitalization rate for COVID-19 was 0.6% in Parkinson's disease, 3.3% in parkinsonism, and 0.7% in controls. The adjusted hazard ratio (age, sex, district, Charlson Index) was 0.8 (95% CI, 0.3-2.3, P = 0.74) in Parkinson's disease and 3.3 (1.4-7.6, P = 0.006) in parkinsonism compared with controls. Twenty-nine of the infected subjects died; 30-day fatality rate was 35.1%, without difference among the 3 groups. Six of 10 Parkinson's disease/parkinsonism patients had the infection during hospitalization or in a nursing home. CONCLUSIONS: Parkinson's disease per se probably is not a risk factor for COVID-19 hospitalization. Conversely, parkinsonism is an independent risk factor probably because of a more severe health status, entailing higher care dependence and placement in high-infection-risk accommodations. © 2020 The Authors.

Performing sleep studies after the COVID-19 outbreak: practical suggestions from Bologna's sleep unit.

The Coronavirus Disease 2019 (COVID-19) pandemic required a thorough re-organization of every sector of the healthcare system. Sleep laboratories need to renew protocols in order to guarantee the safety of patients and healthcare staff while providing exams. Polysomnography (PSG) examinations are essential for the diagnosis and treatment management of several sleep disorders, which may constitute a public or personal safety issue such as obstructive sleep apnea syndrome. Here we provide some practical advice on how to perform sleep studies after the COVID-19 outbreak based on our experience, the review of the existing literature and current national and international recommendations by Health Authorities. We believe that with appropriate precautions it is possible to guarantee a safe restart of PSG and other sleep studies.

Testing cardiovascular autonomic function in the COVID-19 era: lessons from Bologna's Autonomic Unit.

The coronavirus disease 2019 (COVID-19) pandemic has changed the way most medical procedures are performed. Autonomic units, as well as other healthcare sectors, are required to undergo a thorough reorganization of the protocols in order to guarantee the safety of patients and healthcare staff. Cardiovascular autonomic function testing (CAFT) is necessary in certain situations; however, it poses several concerns which need to be addressed. Here, we provide some practical advice based on current national and international health authorities' recommendations and our experience about how to perform CAFT during the COVID-19 emergency. We examine aspects regarding patients, healthcare staff, laboratory preparation, and test performance.
