ABSTRACT
Objetivo: Criar um escore preditivo de mortalidade hospitalar em pacientes submetidos à cirurgia carddíaca e admitidos em duas Unidades de Terapia Intensiva Cirúrgica, analisando variáveis pré, per e de primeiro dia de pós-operatório.Métodos: Coorte clássica de 1458 pacientes internados consecutivamente no período de junho 2000 até março de 2003, com 46 variáveis previamente definidas. a análise estatística consistiu em análise univariada, seguida de regressão logística (RL), com teste de tendência linear e curva ROC.Resultados:Após, as variáveis selecionadas com os respectivos OR foram: idade entre 65 e 75 anos (2,05);idade maior ou igual 75 anos (4,79); diâmetro do átrio esquerdo maior 45mm (2,58)...

This prospective consecutive observational study describes the blood levels of macrophage migration inhibitory factor (MIF), other cytokines, and markers of acute-phase response in 49 consecutive patients who developed the clinical syndrome of sepsis after cardiac surgery. Before starting antimicrobial treatment, all patients underwent microbiologic screening, and blood samples were collected. These samples subsequently were assayed for MIF, macrophage chemoattractant protein-1 (MCP-1), tumor necrosis factor-alpha (TNF-alpha), interleukin (IL)-6 and -10, procalcitonin (PCT), and C-reactive protein (CRP). Patients with positive cultures (n = 25) had a higher mortality (P = 0.046) and higher levels of MIF (P < 0.001) than those with negative cultures (n = 24). We could not detect significant difference between the groups concerning the levels of CRP, PCT, IL6, IL10, MCP-1, or TNF-alpha. MIF levels showed an area under receiver operator curve of 0.823 for the prediction of culture-proven bacterial infection, with the best cut-off value at 988.5 pg/mL. In conclusion, circulating levels of MIF could be indicated as a valuable marker of microbiologically documented sepsis in patients after cardiac surgery, which suggests that MIF may be prospectively explored as a useful diagnostic tool in this setting.
