          Abstract

          RESUMEN Objetivo: Evaluar las actuaciones nutricionales en pacientes con diagnóstico de neumonía COVID-19 en una Unidad de Cuidados Intensivos (UCI) y su ajuste a las guías de las sociedades Europea y Americana de Nutrición Clínica. Metodología: Estudio retrospectivo observacional de 2 meses de duración en pacientes con diagnóstico de neumonía COVID-19 con ingreso en UCI. Se utilizaron los programas ICCA®, OrionClinic® y Kabisoft® para obtener las variables de los pacientes. Resultados: Ingresaron 27 pacientes, de los cuales 20 precisaron soporte nutricional. Un 65% eran hombres y la media de edad fue 62±13,2 años. Los requerimientos energéticos teóricos fueron entre 1.535-1.800 Kcal/día. Permanecieron 2,5±4,5 días en planta previo a su estancia en UCI, que fue de 17±6,9 días. Al término del estudio, el 15% de pacientes fueron alta, el 35% seguían hospitalizados y el 50% fueron éxitus. La variación de los datos analíticos al ingreso y alta fue: proteínas +1,3 g/dl, albúmina +1,2 g/dl, linfocitos +0,5*103/mm3, PCR -114,5 mg/l y triglicéridos +19,4 mg/dl. Un 10% recibieron remdesivir y un 30% tocilizumab como tratamientos de segunda línea. Todos fueron intubados y tratados con propofol; el 75% requirió posición decúbito prono. Todos los pacientes requirieron nutrición enteral, siendo la fórmula hiperproteica-hipercalórica con fibra la más utilizada. Un 70% necesitó nutrición parenteral total, utilizándose formulaciones hiperproteicas-hipocalóricas de forma prioritaria y suplementadas con vitaminas y oligoelementos. Conclusión: Dentro del complicado manejo de este tipo de pacientes, las intervenciones nutricionales han sido necesarias en un 75% de ellos y la adherencia a las guías actuales se ha dado en todos los casos, con resultados favorables.

          SUMMARY Purpose: Evaluate nutritional performance in patients with COVID-19 pneumonia admitted to the Intensive Care Unit (ICU). Adjustment done following the guidelines of the European and American societies for Clinical Nutrition. Methodology: Retrospective observational during 2 months study of some patients with pneumonia by COVID-19 in ICU. Informatic programs ICCA®, OrionClinic® and Kabisoft® were used to obtain variables of patients. Results: 27 patients were admitted in ICU, while 20 of them required nutritional support. There were 65% of men with average age about 62±13.2. Their theoretical nutritional requirements were between 1,535-1,800 kcal/day. They stayed 2.5±4.5 days in the hospital before their ICU admission. They were 17±6.9 days on average in ICU. At the end of this study, 15% of patients were discharged, 35% were hospitalized, and 50% were dead. The variation of the analytical data at admission and discharge was: proteins +1.3 g/dl, albumin +1.2 g/dl, lymphocytes +0.5*103/mm3, PCR -114.5 mg/l and triglycerides +19.4 mg/dl. 10% took remdesivir and 30% tocilizumab. All of them were intubated and treated with propofol and 75% required prone position. All of patients required enteral nutrition being the hyperprotein-hypercaloric with fiber formula the most used. 70% required central total parenteral nutrition being mostly hyperprotein-hypocaloric and supplemented with vitamins and trace elements. Conclusion: Within the complicated management of this type of patients, nutritional interventions have been necessary in 75% of them and adherence to current guidelines has occurred in all cases, with favorable results.

          Compassionate Use of Remdesivir for Patients with Severe Covid-19

          Abstract Background Remdesivir, a nucleotide analogue prodrug that inhibits viral RNA polymerases, has shown in vitro activity against SARS-CoV-2. Methods We provided remdesivir on a compassionate-use basis to patients hospitalized with Covid-19, the illness caused by infection with SARS-CoV-2. Patients were those with confirmed SARS-CoV-2 infection who had an oxygen saturation of 94% or less while they were breathing ambient air or who were receiving oxygen support. Patients received a 10-day course of remdesivir, consisting of 200 mg administered intravenously on day 1, followed by 100 mg daily for the remaining 9 days of treatment. This report is based on data from patients who received remdesivir during the period from January 25, 2020, through March 7, 2020, and have clinical data for at least 1 subsequent day. Results Of the 61 patients who received at least one dose of remdesivir, data from 8 could not be analyzed (including 7 patients with no post-treatment data and 1 with a dosing error). Of the 53 patients whose data were analyzed, 22 were in the United States, 22 in Europe or Canada, and 9 in Japan. At baseline, 30 patients (57%) were receiving mechanical ventilation and 4 (8%) were receiving extracorporeal membrane oxygenation. During a median follow-up of 18 days, 36 patients (68%) had an improvement in oxygen-support class, including 17 of 30 patients (57%) receiving mechanical ventilation who were extubated. A total of 25 patients (47%) were discharged, and 7 patients (13%) died; mortality was 18% (6 of 34) among patients receiving invasive ventilation and 5% (1 of 19) among those not receiving invasive ventilation. Conclusions In this cohort of patients hospitalized for severe Covid-19 who were treated with compassionate-use remdesivir, clinical improvement was observed in 36 of 53 patients (68%). Measurement of efficacy will require ongoing randomized, placebo-controlled trials of remdesivir therapy. (Funded by Gilead Sciences.)

            Effective treatment of severe COVID-19 patients with tocilizumab

            Significance In patients with coronavirus disease 2019, a large number of T lymphocytes and mononuclear macrophages are activated, producing cytokines such as interleukin-6 (IL-6), which bind to the IL-6 receptor on the target cells, causing the cytokine storm and severe inflammatory responses in lungs and other tissues and organs. Tocilizumab, as a recombinant humanized anti-human IL-6 receptor monoclonal antibody, can bind to the IL-6 receptor with high affinity, thus preventing IL-6 itself from binding to its receptor, rendering it incapable of immune damage to target cells, and alleviating the inflammatory responses.

              In Vitro Antiviral Activity and Projection of Optimized Dosing Design of Hydroxychloroquine for the Treatment of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)

              Abstract Background The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) first broke out in Wuhan (China) and subsequently spread worldwide. Chloroquine has been sporadically used in treating SARS-CoV-2 infection. Hydroxychloroquine shares the same mechanism of action as chloroquine, but its more tolerable safety profile makes it the preferred drug to treat malaria and autoimmune conditions. We propose that the immunomodulatory effect of hydroxychloroquine also may be useful in controlling the cytokine storm that occurs late-phase in critically ill SARS-CoV-2 infected patients. Currently, there is no evidence to support the use of hydroxychloroquine in SARS-CoV-2 infection. Methods The pharmacological activity of chloroquine and hydroxychloroquine was tested using SARS-CoV-2 infected Vero cells. Physiologically-based pharmacokinetic models (PBPK) were implemented for both drugs separately by integrating their in vitro data. Using the PBPK models, hydroxychloroquine concentrations in lung fluid were simulated under 5 different dosing regimens to explore the most effective regimen whilst considering the drug’s safety profile. Results Hydroxychloroquine (EC50=0.72 μM) was found to be more potent than chloroquine (EC50=5.47 μM) in vitro. Based on PBPK models results, a loading dose of 400 mg twice daily of hydroxychloroquine sulfate given orally, followed by a maintenance dose of 200 mg given twice daily for 4 days is recommended for SARS-CoV-2 infection, as it reached three times the potency of chloroquine phosphate when given 500 mg twice daily 5 days in advance. Conclusions Hydroxychloroquine was found to be more potent than chloroquine to inhibit SARS-CoV-2 in vitro.
