ABSTRACT
Background. COVID-19 is caused by SARS-CoV-2 virus and in many cases lead to a pneumonia. However a number of neumuscular manifestations have been associated to SARS-CoV-2 infection. Furthermore, multiorgan symptoms after COVID-19 are being reported by increasing numbers of patients, ranging from cough to fatigue and muscle pain. However, the long-term health consequences of COVID-19 remain largely unclear. Methods: We evaluated 124 patients hospitalized between march and May 2020 for SARS-COV-2 associated pneumonia at 6 and 12 months. We retrospectively collected clinical, laboratory and radiological information available. for each patient, cognitive tests, scales for depression and anxiety and a specific Fatigue Severity Scale (FSS) were performed. Results. Twenty-five patients died during hospitalization. At 12 months follow up 85 patient were evaluated. Eighty-seven (70%) patiens were male and mean age was 67.3 years. During hospitalization 43 (36.5%) of patients complain of myalgia. This patients had higher CK levels than patients who did not (534 U/L vs 93 U/l, p < 0.001). At 12 months 42% of patients complain about myalgia while 34% about fatigue. Mean FSS value were 32.93, and were significatively higher in patiets who complain about fatigue (41.52 vs 27.08 p < 0.001) and Muscle pain (40.84 vs 26.80, p < 0.001) compared to who did not. Conclusions. During hospitalization for COVID-19 myalgia was associated with an higher level of CK, suggesting a possible muscle involvement. At 12 month myalgia and fatigue were present in a more than a third of patient suggesting that this manifestation could be one of the main COVID-19 sequelae.
ABSTRACT
Background and aims: Objective: Several preclinical and clinical investigations have argued for nervous system involvement in SARS-CoV-2 infection. No data about clinical, imaging and biomarkers presentations as well as long-term outcomes are available for SARS-CoV-2 encephalitis in comparison with infectious and autoimmune encephalitis. Methods: The ENCOVID European registry included patients with probable or definite diagnosis of encephalitis with and without SARS-CoV-2 infection admitted for hospitalization in the European recruiting centers between February 1st 2020 and March 30th, 2021. Each patient underwent a standardized assessment including full infectious screening, CSF, EEG, MRI data. Clinical presentation and laboratory markers, severity of COVID-19 disease, response to treatment and outcomes were recorded. Results: Results – Out of 155 cases screened, forty-five cases of encephalitis positive for SARS-CoV-2 infection and 63 without COVID-19 with full available data were included. SARS-CoV-2 encephalitis exhibited common presentation with aphasia and dysarthria compared to non-COVID- encephalitis and exhibited higher prevalence of patients with normal MRI but mild hyperproteinorracchia/pleocytosis. Most SARS-CoV-2 cases appeared during the onset of COVID-19 and exhibited different response to treatment and long-term outcomes compared to non COVID encephalitis. Conclusions: Conclusions –The registry identified a wide spectrum of encephalitis associated with COVID19 infection, with clinical characteristics and course different from classical infectious and autoimmune encephalitis. Biomarkers studies are warranted in order to evaluate the specific inflammatory pathways associated with SARS-Cov-2 encephalitis.
