ABSTRACT
Background: Recent studies suggest that baricitinib added to dexamethasone may reduce mortality in hospitalized COVID-19 patients requiring supplemental oxygen Methods: In a multicenter open-label, pragmatic, randomized clinical trial in 25 hospitals in Spain we included symptomatic participants with SARS-CoV-2 detected by PCR or antigenic test, with a creatinine clearance >60 mL/min, > 60 years or younger if they had at least two comorbidities (hypertension, obesity, diabetes, cirrhosis, chronic neurologic disease, active cancer, heart failure, coronary heart disease or COPD). Participants were initially randomized to receive or not tenofovir disoproxil fumarate/emtricitabine (TDF/FTC). At any moment during the trial participants with room air 02 saturation < 95% and at least one increased inflammatory biomarker could be randomized to dexamethasone (D) or dexamethasone plus baricitinib (DB). Primary outcome was 28 days mortality. Secondary outcomes were disease progression (increase of O2 requirements, mechanical ventilation or increase in medical therapy: steroid dose, need for starting tocilizumab) Results: Out of the 355 participants included in the trial 287 (80.8%) were randomized to D (n=142) or DB (n=145), 264 (91.9%) simultaneously with the TDF/FTC randomization and 23 (8.1%) later on. Median age 67 years (IQR 62, 73), male (65.5%), with median 8 days of symptoms (IQR 5-10), 28.6% with ≤ 5 days of symptoms, 100% hospitalized, 31.6% with one and 38.7% with ≥ 2 comorbidities (most common: 35.9% hypertension, 9.4% diabetes, 1.7 % obesity), 14.3% receiving remdesivir and 49.1% TDF/FTC. Endpoints in participants treated with D vs. those treated with DB favored DB without achieving statistical significance: mortality 4.9%/2.1%, disease progression 27.5%/24.8%, mechanical ventilation (invasive or noninvasive) 25.4%/23.4%, days since randomization until discharge (median [IQR]) 7 [5, 12]/7 [5, 13.5], discharge before 28 days 89%/94.2%. By Cox regression Hazard Ratio (95% CI) of 28-day mortality was 0.51 (0.13-2.06) for participants treated with DB. Serious adverse events occurred in 9.9%/9.7% of participants treated with D or DB respectively. Adverse events leading to B discontinuation occurred in 3.45% of participants. Conclusion: In this clinical trial of high-risk patients with COVID-19 all disease outcomes favored baricitinb added to dexamethasone but differences did not reach statistical significance. Overall mortality was unexpectedly low.
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
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.
