ABSTRACT
RESUMEN Introducción: muchos casos de covid-19 son asintomáticos al ingresar. El desarrollo de síntomas pudiera tener relación con la terapéutica empleada. Objetivo: caracterizar clínicamente los pacientes infectados con SARS-CoV-2 y la evolución de los síntomas en relación con el ingreso, en el Hospital Militar Docente Dr. Mario Muñoz Monroy, de Matanzas. Materiales y métodos: estudio retrospectivo de las historias clínicas de pacientes ingresados confirmados con SARS-CoV-2 hasta el 26 de junio de 2020. Se estudiaron 145 pacientes, divididos en dos grupos: sintomáticos y asintomáticos al ingresar. Se recabaron datos demográficos, antecedentes patológicos personales, síntomas y evolución, parámetros humorales, tratamiento, estadía hospitalaria y complicaciones. Se utilizaron las pruebas de Chi cuadrado y de U de Mann-Whitney, según el tipo de variable. Resultados: la mayoría de los pacientes ingresó sintomático. Solo hasta 19 años predominaron los asintomáticos. Los hipertensos, diabéticos y con insuficiencia renal tuvieron mayor proporción de sintomáticos al momento del ingreso. Un pequeño grupo (n= 38) nunca desarrollo síntomas. En los sintomáticos predominaron tos, malestar general, fiebre, dolor faríngeo, congestión nasal, anosmia y falta de aire. Posterior al ingreso prevalecieron diarreas, dispepsia y vómitos. Los sintomáticos tuvieron mayores valores de enzimas hepáticas, más infección respiratoria baja y distress respiratorio, así como estadía hospitalaria extensa, ingreso en cuidados intensivos y fallecidos. Conclusiones: más de la mitad de los pacientes ingresaron con predominio de síntomas generales y respiratorios. Después del ingreso predominó la sintomatología digestiva, posiblemente relacionada con la terapéutica empleada. Los pacientes sintomáticos al ingresar, tuvieron peores parámetros humorales, más complicaciones y estadía hospitalaria más prolongada (AU).
ABSTRACT Introduction: many cases of covid-19 are asymptomatic when admitted to the hospital. The development of symptoms may be related to the therapies used. Objective: to characterize clinically the patients infected with SARS-CoV-2 and the evolution of symptoms in relation to admission, in the Military Hospital Dr. Mario Muñoz Monroy, of Matanzas. Materials and methods: retrospective study of clinical records of SARS-CoV-2-confirmed patients admitted up to June 26, 2020. 145 patients were studied, divided into two groups: symptomatic and asymptomatic ones at admission. Demographic data, personal pathological history, symptoms and evolution, humoral parameters, treatment, hospital stay and complications were collected. The Chi square and Mann-Whire U tests were used, depending on the type of variable. Results: most patients were symptomatic at admission. Asymptomatic ones predominated only up to 19 years. Hypertensive, diabetic and renal impaired patients had a higher proportion of symptoms at admission. A small group (n = 38) never developed symptoms. Cough, general discomfort, fever, pharyngeal pain, nasal congestion, anosmia and shortness of breath were the predominated symptoms. Diarrhea, dyspepsia and vomiting prevailed after admission. The symptomatic patients showed higher liver enzyme values, more low respiratory infection and respiratory distress, and also had more extended hospital stay, admission to intensive care and deceases. Conclusions: more than half of the patients were admitted with predominance of general and respiratory symptoms. After admission, digestive symptoms predominated, possibly related to the therapies used. Symptomatic patients on admission had worse humoral parameters, more complications and longer hospital stay (AU).

El SARS-CoV 2 es un RNA virus, que desde el punto de vista clínico puede manifestarse con neumonía, compromiso neurológico, miocárdico, renal, coagulopatía, disfunción orgánica múltiple o la muerte. Se presenta el caso de un varón que ingresó a la unidad de cuidados intensivos (UCI) por síndrome de distress respiratorio agudo severo secundario a infección por SARS-CoV 2, quien requirió ventilación mecánica invasiva con ciclos de pronación, noradrenalina. En la evolución cursó con injuria renal aguda oligúrica, con orina oscura rojiza y con niveles de creatinfosfoquinasa (CPK) séricas en 17 179 UI/ml, considerando rabdomiolisis secundaria a infección por SARS- CoV 2 como una de las causas de la misma, el paciente fue sometido a hemodiálisis, con mejoría progresiva, sobrevivencia y alta de UCI.
SUMMARY SARS-CoV-2 is an RNA virus that can manifest clinically with pneumonia, neurologic, myocardial and renal involvement as well as with hematologic and multiple organ failure and death. We report the case of a male patient admitted to the ICU severe acute respiratory distress associated to SARS-CoV-2 infection who required mechanical ventilation with pronation and vasopressors. He developed acute kidney injury with reddish urine and serum levels of CK in 17,179 UI/ml consistent with SARS-CoV-2 associated rhabdomyolysis. The patient underwent hemodialysis with complete recovery and subsequent discharge from the ICU.
ABSTRACT
Social distancing was planned as a preventive measure to control the extensive spread of COVID-19. COVID-19-related deaths in Brazil were analyzed during the period of social distancing measures. Mortality data for COVID-19 was obtained from the Worldometer website (www.worldometer.info). Deaths were estimated up to the 31st day after the occurrence of the 5th COVID-19-related death in Brazil. Social distance was measured using Google's community mobility reports (https://www.google.com/covid19/mobility/). The Brazilian epidemic curves were interconnected, and mathematical models were evaluated to fit the mortality estimation curves. The optimistic model was defined in the opening period of social distancing and, therefore, in the lower mobility (40-60%). The realistic model was calculated according to relaxed social distance measures (<40%) and the pessimistic model was calculated based on the transmission rate between 2-3. Thus, the equations of the mathematical models provided the outcomes for the date of June 9, 2020, as follows: realistic model with 40,623 deaths, pessimistic model with 64,310 deaths and the optimistic model with a projection of 31,384 deaths. As a result of these analyzes, on May 24, 2020, there were a total of 22,965 deaths related to COVID-19, and those deaths included within the proposed mathematical models were 17,452 for the optimistic model, 22,623 for the realistic model and 32,825 for the pessimistic model. Thus, it is concluded that social distancing measures promoted by the Brazilian public managers contributes to the reduction in approximately ten thousand deaths related to COVID-19 in the current pandemic scenario.
INTRODUÇÃO: O distanciamento social foi planejado como uma medida preventiva para controlar a disseminação extensiva da COVID-19. Nós analisamos as mortes relacionadas à COVID-19 no Brasil durante o período de medidas de distanciamento social. Os dados de mortalidade do COVID-19 foram obtidos no site da Worldometer (www.worldometer.info). As mortes foram estimadas até o 31º dia após a 5ª morte. O distanciamento social foi medido por meio dos relatórios de mobilidade comunitária COVID-19; Google (https://www.google.com/covid19/mobility/). As curvas epidêmicas brasileiras foram interligadas e os modelos matemáticos foram avaliados para se ajustarem às curvas de estimativa de mortalidade. O modelo otimista foi fundado no período de abertura da distância social e, portanto, na menor mobilidade (40-60%). O modelo realista foi calculado de acordo com medidas de distanciamento social relaxado (<40%) e o modelo pessimista foi calculado com base em R0 entre 2-3. Sob essa situação, o modelo matemático realista estimou 40.623 mortes em 9 de junho de 2020, enquanto o modelo pessimista antecipou 64.310 mortes e o modelo otimista projetou 31.384. Até hoje (24 de maio de 2020), um total de 22.965 foram relatadas, enquanto nosso modelo projetou 17.452 para o modelo otimista, 22.623 para o modelo realista e 32.825 para o modelo pessimista. Observamos movimento reduzido ao longo deste período. Em resumo, o modelo matemático sugere que a mobilidade reduzida da comunidade diminuiu o total estimado de mortes relacionadas à COVID-19 no Brasil. Enfatizamos que mais procedimentos metodológicos serão necessários para confirmar esta teoria
