Introduction: Parkinson's disease (PD) is more frequent in the elderly and increases the risk of respiratory infections. Previous data on PD and SARS-CoV-2 are scarce, suggesting a poor prognosis in advanced disease and second-line therapies. Methods: A retrospective case–control study comparing patients with PD and COVID-19 and patients with PD without COVID-19 was conducted during the pandemic period in Spain (March 1st–July 31st 2020) in a tertiary university hospital. Results: Thirty-nine (COVID-19 +) and 172 (COVID-19-) PD patients were included. Fifty-nine percent were males in both groups, with similar age (75.9 ± 9.0 COVID-19 + , 73.9 ± 10.0 COVID-19-), disease duration (8.9 ± 6.2 COVID-19 + , 8.5 ± 5.6 COVID-19-) and PD treatments. COVID-19 was mild in 10 (26%), required admission in 21 (54%) and caused death in 8 (21%) patients. Dementia was the only comorbidity more frequent in COVID-19 + patients (36% vs. 14%, p = 0.0013). However, in a multivariate analysis, institutionalization was the only variable associated with COVID-19 + (OR 17.0, 95% CI 5.0–60.0, p < 0.001). When considering severe COVID-19 (admission or death) vs. mild or absent COVID-19, institutionalization, neoplasm, dementia and a lower frequency of dopamine agonists were associated with severe COVID-19. In multivariate analysis, only institutionalization [OR 5.17, 95% CI 1.57–17, p = 0.004] and neoplasm [OR 8.0, 95%CI 1.27–49.8, p = 0.027] remained significantly associated. Conclusion: In our experience, institutionalization and oncologic comorbidity, rather than PD-related variables, increased the risk of developing COVID-19, and impacted on its severity. These findings suggest that epidemiologic factors and frailty are key factors for COVID-19 morbidity/mortality in PD. Appropriate preventive strategies should be implemented in institutionalized patients to prevent infection and improve prognosis. [ABSTRACT FROM AUTHOR]

The role of immunosuppression among coronavirus disease 2019 (COVID-19) patients has not been elucidated and management may be challenging. This observational study included confirmed COVID-19 patients. The primary endpoint was the development of moderate-severe acute respiratory distress syndrome (ARDS). Time to moderate-severe ARDS, the need for mechanical or noninvasive ventilation (MV/NIV), death, and a composite of death or MV/NIV were secondary endpoints. Of 138 patients included, 27 (19.6%) were immunosuppressed (IS) and 95 (68.8%) were male, with a median (IQR) age of 68 (54-78) years. A significantly lower proportion of IS patients (25.9%) compared to non-IS patients (52.3%) developed moderate-severe ARDS, in both unadjusted (0.32; 95% CI, 0.13-0.83; p = .017) and adjusted (aOR, 0.25; 95% CI, 0.08-0.80; p = .019) analyses. After stratifying by pathologies, only IS patients with autoimmune diseases remained significant (aOR 0.25; 95% CI, 0.07-0.98; p = .046). Nonsignificant trends toward a longer time to moderate or severe ARDS, a lower need for MV/NIV, and a lower risk of death or MV/NIV were detected among IS. In our cohort of COVID-19 patients, nonsevere immunosuppression was associated with a lower risk of moderate-severe ARDS, especially among AD. This suggests a potential protective effect from a hypothesized hyper-inflammatory response., (© 2020 Wiley Periodicals LLC.)

Introduction: An increased incidence of stroke in HIV-infected patients has already been reported, suggesting that HIV infection may be a cerebrovascular risk factor. The objective of this study was to assess temporal trends in the proportion of HIV infection among patients with stroke in Spain., Methods: Data were obtained from the minimum basic dataset (MBDS) of all patients hospitalized in Spain between 1997 and 2012 with a primary or secondary diagnosis of stroke. The annual proportion of HIV infection and time trends (stratifying by type of stroke and HIV stage) were calculated, and predictors of HIV infection and the social and economic impact of HIV-infected (HIV+) and non-infected (HIV-) patients were analyzed., Results: Of 857,371 patients hospitalized with an incident stroke, 2134 (0.25%) had HIV infection. A 2.5% year-on-year increase (OR 1.025, 95% CI 1.015-1.036, p<0.0001) of the proportion of HIV-infected patients was observed due to an increase in the asymptomatic stage of the infection (per year OR 1.077, 95% CI 1.057-1.097, p<0.0001), as the proportion of patients with AIDS remained stable. Factors independently associated with HIV infection and stroke were active smoking, stimulating drugs and hepatitis C virus (HCV) infection. A higher mortality rate, longer hospital stay and a higher cost per hospitalized patient was observed among HIV+ patients., Conclusions: From 1997 to 2012, there was an increase in the proportion of HIV infection among patients hospitalized with stroke irrespective of the classical vascular risk factors, reinforcing the role of HIV infection as a cerebrovascular risk factor., (Copyright © 2019 Elsevier España, S.L.U. and Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.
