ABSTRACT

ABSTRACT COVID-19 is a disease whose knowledge is still under construction, high transmissibility, with no consensual treatment available to everyone. Therefore, the identification of patients at higher risk of evolving to the critical form of the disease is fundamental. The study aimed to determine risk factors associated with the severity of COVID-19 in adults patients. This is an observational, retrospective study from a cohort of adult patients with COVID-19 admitted to a public hospital from March to August 2020, whose medical records were evaluated. For the association of possible severity predictors, a Poisson regression was used. The primary outcome was the critical form of the disease (need for admission to the Intensive Care Unit and/or invasive mechanical ventilation). We included 565 patients: mostly men; 55.5% of those who progressed to the critical form of the disease were over sixty years old. Hypertension, diabetes mellitus and obesity were the most frequent comorbidities. There were 39.8% of patients who progressed to the critical form of the disease. The hospital mortality rate was 22.1%, and that of critical patients was 46.7%. The independent factors associated with the severity of the disease were obesity [RR = 1.33 (95% CI 1.07 to 1.66; p = 0.011)], SpO2/FiO2 ratio ≤ 315 [RR = 2.20 (95% CI 1.79 to 2.71; p = 0.000)], C-reactive protein > 100 mg/L [RR = 1.65 (95% CI 1.33 to 2.06; p = 0.000)], and lymphocytes < 1,000/µL [RR = 1.44 (95% CI 1.18 to 1.75; p = 0.000)]. Advanced age and comorbidities were dependent factors strongly associated with the critical form of the disease.

ABSTRACT

ABSTRACT Objective: To evaluate the association between obesity and levels of high-sensitivity C-reactive protein (hs-CRP) in patients with heart failure admitted to a tertiary hospital. Methods: Cross-sectional study with a consecutive sampling of hospitalized patients with heart failure. Sociodemographic and clinical data were collected, and the nutritional status was assessed through indicators such as body mass index (in kg/m2), waist circumference (in cm), waist-hip ratio, triceps skinfold (in mm) and subscapularis skinfold (in mm). Neck circumference (in cm) was measured as well as serum levels of hs-CRP, in mg/L. Results: Among 123 patients, the mean age was 61.9±12.3 years and 60.2% were male. The median of hs-CRP was 8.87mg/L (3.34 to 20.01). A tendency to an inverse correlation between neck circumference and hs-CRP was detected (r=-0.167; p=0.069). In the multiple linear regression analysis, after adjustment for age, disease severity (NYHA classification III and IV, low ejection fraction, left ventricular dysfunction during diastole), and infectious conditions there was an inverse association between hs-CRP and neck circumference (ß=-0.196; p=0.03) and subscapularis skinfold (ß=-0.005; p=0.01) in the total sample, which was not maintained after the stratification by sex. Conclusion: Increased levels of hs-CRP in patients hospitalized for heart failure were not associated with obesity.


RESUMO Objetivo: Avaliar a associação entre obesidade e níveis de proteína c-reativa ultrassensível (PCR-us) em pacientes com insuficiência cardiac admitidos em um hospital terciário. Métodos: Estudo transversal com amostragem consecutiva de pacientes com insuficiência cardíaca hospitalizados. Foram coletados dados sociodemográficos e clínicos, e o estado nutricional foi avaliado por meio de indicadores como índice de massa corporal (em kg/m2), circunferência da cintura (em cm), razão cintura-quadril, dobra cutânea tricipital (em mm) e dobra cutânea subescapular (em mm). Circunferência do pescoço (em cm) foi aferida bem como níveis séricos de PCR-us, em mg/L. Resultados: Em 123 pacientes, a média da idade foi 61,9±12,3 anos, e 60,2% eram do sexo masculino. A mediana de PCR-us foi de 8,87mg/L (3,34 a 20,01). Detectou-se tendência à correlação inversa entre circunferência do pescoço e PCR-us (r=-0,167; p=0,069). Na análise por regressão linear múltipla, após ajustes para idade, gravidade da doença (classificação NYHA III e IV, fração de ejeção baixa, disfunção ventricular esquerda durante a diástole) e quadros infecciosos, houve associação inversa entre PCR-us e circunferência do pescoço (ß=-0,196; p=0,03) e dobra cutânea subescapular (ß=-0,005; p=0,01) na amostra total, que não se manteve após estratificação para sexo. Conclusão: O aumento dos níveis de PCR-us em pacientes hospitalizados por insuficiência cardíaca não se associou à obesidade.

ABSTRACT

As doenças ateroscleróticas constituem a principal causa de mortalidade em todo o mundo. Na prevenção das doenças cardiovasculares, o manejo da hipertensão, diabetes mellitus e dislipidemia é fundamental. A doença arterial periférica é uma importante manifestação de aterosclerose sistêmica e poderosa preditora de futuros eventos cerebrovasculares e cardiovasculares, como infarto do miocárdio e acidente vascular cerebral. Vários estudos sugerem que o índice tornozelo-braquial, uma medida não-invasiva da doença arterial periférica, é altamente preditivo de subseqüente mortalidade e morbidade cardiovasculares em pacientes hipertensos. Um simples marcador de risco cardiovascular pode permitir screening populacional e estratificar pacientes que necessitam de tratamento mais intensivo. O índice tornozelo-braquial é de fácil obtenção, útil para melhorar a estratificação de risco cardiovascular e parece ter um lugar na rotina de avaliação clínica em pacientes hipertensos.
