ABSTRACT
Introducción Nos proponemos analizar las complicaciones neurológicas de los pacientes con infección grave por SARS-CoV-2 que han requerido ingreso en unidad de cuidados intensivos (UCI). Pacientes y métodos Estudio descriptivo retrospectivo, observacional, de pacientes consecutivos ingresados en UCI por infección respiratoria grave por SARS-CoV-2 desde el 1 de abril hasta el 1 de junio de 2020. Resultados Registramos 30 pacientes con síntomas neurológicos, 21 hombres (72,40%), edad media: 57,41 años ± 11,61 desviación estándar (DE). Estancia media en UCI: 18,83 ± 14,33 DE. A nivel sindrómico: 28 pacientes (93,33%) con síndrome confusional agudo, 15 (50%) con patología neuromuscular, 5 (16,66%) con cefalea, 4 (13,33%) con patología cerebrovascular y 4 (13,33%) con encefalopatías/encefalitis. Punción lumbar normal en 6 pacientes (20%). La RMN craneal o TAC craneal mostró alteraciones en 20 casos (66,6%). Se realizó EEG en todos los pacientes (100%), alterado en 8 pacientes (26,66%). En 5 de los 15 pacientes con miopatía clínica se ha podido confirmar con ENMG. Hemos encontrado relación entre la mayor edad y los días de ingreso en UCI (p = 0,002;IC 95%: 4,032-6,022;OR: 3,594). Conclusiones La infección grave por COVID-19 afecta mayoritariamente a hombres, similar a lo descrito en otras series. La mitad de nuestros pacientes presenta una miopatía aguda, y casi la totalidad de los pacientes salen de la UCI con síndromes confusionales agudos que evolucionan a una resolución completa, sin correlacionarse con los resultados del EEG o de pruebas de neuroimagen. La mayor edad se asocia con un mayor número de días de estancia en UCI.
ABSTRACT
Background and importance Tocilizumab is an anti-human IL-6 receptor monoclonal antibody used in the treatment of cytokine release syndrome in patients with pneumonia associated with coronavirus disease. Despite the data from the COVACTA study, tocilizumab continues to be the gold standard for patients in our centre. Aim and objectives To describe the use of tocilizumab in the first peak versus the second peak of the SARS-CoV-2 pandemic, and to describe the results of the use of tocilizumab in both situations. Material and methods All patients treated with tocilizumab were included in the study periods: first peak (March to June 2020) and second peak (August to the present 2020). Demographic and clinical variables were collected. Data were obtained from the electronic medical records and prescription applications. Results 65 patients were included, 36 patients (55.38%) in the first peak versus 29 patients (44.62%) in the second peak. Conclusion and relevance In the first peak, tocilizumab was prescribed to more serious patients: those admitted to the ICU, with a higher FINE score and needing aggressive support therapy. In addition, it was prescribed in patients with a higher D-dimer. Doses and number of administrations were higher in the first peak. New scientific evidence led to the use of different concomitant treatments in the second peak: corticosteroids (second peak dexamethasone versus first peak methylprednisolone) and antiviral therapy (only remdesivir in the second peak). In the second peak, hospital and ICU stays were shorter, probably because tocilizumab was used in less serious patients. Despite this, no differences in mortality were observed. A study limitation was sample size (Table Presented).

INTRODUCTION: We analysed the neurological complications of patients with severe SARS-CoV-2 infection who required intensive care unit (ICU) admission. PATIENTS AND METHODS: We conducted a retrospective, observational, descriptive study of consecutive patients admitted to the ICU due to severe respiratory symptoms secondary to SARS-CoV-2 infection between 1 April and 1 June 2020. RESULTS: We included 30 patients with neurological symptoms; 21 were men (72.40%), and mean age (standard deviation [SD]) was 57.41 years (11.61). The mean duration of ICU stay was 18.83 days (14.33). The neurological conditions recorded were acute confusional syndrome in 28 patients (93.33%), neuromuscular disease in 15 (50%), headache in 5 (16.66%), cerebrovascular disease in 4 (13.33%), and encephalopathies/encephalitis in 4 (13.33%). CSF analysis results were normal in 6 patients (20%). Brain MRI or head CT showed alterations in 20 patients (66.6%). EEG was performed in all patients (100%), with 8 (26.66%) showing abnormal findings. In 5 of the 15 patients with clinical myopathy, diagnosis was confirmed with electroneuromyography. We found a correlation between older age and duration of ICU stay (P=.002; 95%CI: 4.032-6.022; OR: 3,594). CONCLUSIONS: Severe COVID-19 mainly affects men, as observed in other series. Half of our patients presented acute myopathy, and almost all patients left the ICU with acute confusional syndrome, which fully resolved; no correlation was found with EEG or neuroimaging findings. Older age is associated with longer ICU stay.
