ABSTRACT
Abstract Objective: To describe the clinical characteristics of children and adolescents admitted to intensive care with confirmed COVID-19. Method: Prospective, multicenter, observational study, in 19 pediatric intensive care units. Patients aged 1 month to 19 years admitted consecutively (March-May 2020) were included. Demographic, clinical-epidemiological features, treatment, and outcomes were collected. Subgroups were compared according to comorbidities, age < 1 year, and need for invasive mechanical ventilation. A multivariable logistic regression model was used for predictors of severity. Results: Seventy-nine patients were included (ten with multisystemic inflammatory syndrome). Median age 4 years; 54% male (multisystemic inflammatory syndrome, 80%); 41% had comorbidities (multisystemic inflammatory syndrome, 20%). Fever (76%), cough (51%), and tachypnea (50%) were common in both groups. Severe symptoms, gastrointestinal symptoms, and higher inflammatory markers were more frequent in multisystemic inflammatory syndrome. Interstitial lung infiltrates were common in both groups, but pleural effusion was more prevalent in the multisystemic inflammatory syndrome group (43% vs. 14%). Invasive mechanical ventilation was used in 18% (median 7.5 days); antibiotics, oseltamivir, and corticosteroids were used in 76%, 43%, and 23%, respectively, but not hydroxychloroquine. The median pediatric intensive care unit length-of-stay was five days; there were two deaths (3%) in the non- multisystemic inflammatory syndrome group. Patients with comorbidities were older and comorbidities were independently associated with the need for invasive mechanical ventilation (OR 5.5; 95% CI, 1.43-21.12; p = 0.01). Conclusions: In Brazilian pediatric intensive care units, COVID-19 had low mortality, age less than 1 year was not associated with a worse prognosis, and patients with multisystemic inflammatory syndrome had more severe symptoms, higher inflammatory biomarkers, and a greater predominance of males, but only comorbidities and chronic diseases were independent predictors of severity.
Resumo Objetivo: Descrever as características clínicas de crianças e adolescentes internados em unidade de terapia intensiva com COVID-19 confirmada. Método: Estudo prospectivo, multicêntrico, observacional, em 19 unidades de terapia intensiva pediátrica. Foram incluídos pacientes entre um mês e 19 anos, admitidos consecutivamente (março a maio de 2020). As características demográficas, clínico-epidemiológicas, o tratamento e os resultados foram coletados. Os subgrupos foram comparados de acordo com as comorbidades, idade < 1 ano e necessidade de ventilação mecânica invasiva. Um modelo de regressão logística multivariável foi utilizado para preditores de gravidade. Resultados: Setenta e nove pacientes foram incluídos (10 com síndrome inflamatória multi-ssistêmica). Mediana de idade, quatro anos; 54% eram do sexo masculino (síndrome inflamatória multissistêmica, 80%); 41% tinham comorbidades (síndrome inflamatória multissistêmica, 20%). Febre (76%), tosse (51%) e taquipneia (50%) foram comuns nos dois grupos. Sintomas graves egastrointestinais e marcadores inflamatórios mais elevados foram mais frequentes na presença de síndrome inflamatória multissistêmica. Infiltrados intersticiais pulmonares foram comuns em ambos os grupos, mas o derrame pleural foi mais prevalente no grupo com síndrome inflamatória multissistêmica (43% vs. 14%). A ventilação mecânica invasiva foi utilizada em 18% (mediana 7,5 dias); antibióticos, oseltamivir e corticosteroides foram utilizados em 76%, 43% e 23%, respectivamente, mas não a hidroxicloroquina. A mediana do tempo de permanência na unidade de terapia intensiva pediátrica foi de 5 dias; duas mortes ocorreram (3%) no grupo não- síndrome inflamatória multissistêmica. Os pacientes com comorbidades eram mais velhos, e as comorbidades foram independentemente associadas à necessidade de ventilação mecânica invasiva(OR 5,5; IC95%, 1,43-21,12; P 0,01). Conclusões: Nas unidades de terapia intensiva pediátrica brasileiras, a COVID-19 apresentou baixa mortalidade, a idade inferior a um ano não foi associada a um pior prognóstico, os pacientes com síndrome inflamatória multissistêmica apresentaram sintomas mais graves, biomarcadores inflamatórios mais elevados e uma grande predominância no sexo masculino, mas apenas a presença de comorbidades e doenças crônicas foi um preditor independente de gravidade.

OBJECTIVE: To describe the case-fatality rate (CFR) and risk factors of death in children with community-acquired acute pneumonia (CAP) in a pediatric university hospital. METHOD: A longitudinal study was developed with prospective data collected from 1996 to 2011. Patients aged 1 month to 12 years were included in the study. Those who left the hospital against medical orders and those transferred to ICU or other units were excluded. Demographic andclinical-etiological characteristics and the initial treatment were studied. Variables associated to death were determined by bivariate and multivariate analysis using logistic regression. RESULTS: A total of 871 patients were selected, of whom 11 were excluded; thus 860 children were included in the study. There were 26 deaths, with a CFR of 3%; in 58.7% of these, penicillin G was the initial treatment. Pneumococcus was the most common pathogen (50.4%). From 1996 to 2000, there were 24 deaths (93%), with a CFR of 5.8% (24/413). From 2001 to 2011, the age group of hospitalized patients was older (p = 0.03), and the number of deaths (p = 0.02) and the percentage of disease severity were lower (p = 0.06). Only disease severity remained associated to death in the multivariate analysis (OR = 3.2; 95%CI: 1.2-8.9; p = 0.02). CONCLUSION: When the 1996-2000 and 2001-2011 periods were compared, a significant reduction in CFR was observed in the latter, as well as a change in the clinical profile of the pediatric in patients at the institute. These findings may be related to the improvement in the socio-economical status of the population. Penicillin use did not influence CFR. .
OBJETIVO: Descrever a taxa de letalidade (TL) e os fatores de risco de óbito em crianças com pneumonia grave adquirida na comunidade (CAP) em um hospital universitário pediátrico. MÉTODO: Foi desenvolvido um estudo longitudinal com dados prospectivos coletados de 1996 a2011. Foram incluídos no estudo pacientes com idade entre 1 mês e 12 anos de idade. Foram excluídos aqueles que deixaram o hospital desconsiderando as recomendações médicas e aqueles transferidos para UTI ou outras unidades. Foram estudadas as características demográficas, clínicas e etiológicas e o tratamento inicial. As variáveis associadas a óbito foram determinadas por análise bivariada e multivariada utilizando regressão logística. RESULTADOS: Foi selecionado um total de 871 pacientes, dos quais 11 foram excluídos; assim, foram incluídas no estudo 860 crianças. Houve 26 óbitos, com uma TL de 3%; em 58,7% desses, penicilina G foi o tratamento inicial. Pneumococo foi o patógeno mais comum (50,4%). De 1996 a 2000, houve 24 óbitos (93%), com uma TL de 5,8% (24/413). De 2001 a 2011, a faixa etária de pacientes internados foi mais velha (p = 0,03) e o número de óbitos (p = 0,02) e o percentual de gravidade das doenças foram menores (p = 0,06). Apenas a gravidade das doenças continuou associada a óbito na análise multivariada (RC = 3,2; IC de 95%: 1,2-8,9; p = 0,02). CONCLUSÃO: Quando os períodos de 1996-2000 e 2001-2011 foram comparados, foi observada uma redução significativa na TL no último período, bem como uma alteração no perfil clínico dos pacientes hospitalizados no instituto. Esses achados podem estar relacionados à melhora na situação socioeconômica da população. O uso de penicilina não influenciou a TL. .

This study developed a predictive model to identify pleural tuberculosis. A consecutive cases study of patients investigating the cause of pleural effusion, in an area of high prevalence of tuberculosis (Rio de Janeiro, Brazil). Clinical and laboratory variables were compared among patients with tuberculosis (TB) and without tuberculosis (NTB), individually and using logistic regression. The performance was described as diagnostic accuracy, compared to a gold standard in a masked way. We have studied 104 TB patients, 41 with malignant, 29 transudates, 28 parapneumonic, 13 with miscellaneous diseases. After identification of individual discrimination power aided by clinical, radiological and laboratory variables, the following ones were included in a multivariate analysis: ADA, total leukocytes, percentile of lymphocytes, protein, lactate dehydrogenase, duration of disease, age and gender. A logistic regression model to predict pleural tuberculosis including the five first variables showed the best performance. A receiver operating characteristic curve identified the best cutoff at 0.7, resulting in a sensitivity and specificity of more then 95 percent. The predictive model improved the specificity of ADA alone, keeping its sensitivity. This model seems helpful when a microbiological or histological diagnosis of pleural tuberculosis could not be established. External validation of these results is necessary before recommendation for routine application.
