RESUMEN
OBJECTIVE: To assess whether a restrictive strategy of RBC transfusion reduces 28-day mortality when compared with a liberal strategy in cancer patients with septic shock. DESIGN: Single center, randomized, double-blind controlled trial. SETTING: Teaching hospital. PATIENTS: Adult cancer patients with septic shock in the first 6 hours of ICU admission. INTERVENTIONS: Patients were randomized to the liberal (hemoglobin threshold, < 9 g/dL) or to the restrictive strategy (hemoglobin threshold, < 7 g/dL) of RBC transfusion during ICU stay. MEASUREMENTS AND MAIN RESULTS: Patients were randomized to the liberal (n = 149) or to the restrictive transfusion strategy (n = 151) group. Patients in the liberal group received more RBC units than patients in the restrictive group (1 [0-3] vs 0 [0-2] unit; p < 0.001). At 28 days after randomization, mortality rate in the liberal group (primary endpoint of the study) was 45% (67 patients) versus 56% (84 patients) in the restrictive group (hazard ratio, 0.74; 95% CI, 0.53-1.04; p = 0.08) with no differences in ICU and hospital length of stay. At 90 days after randomization, mortality rate in the liberal group was lower (59% vs 70%) than in the restrictive group (hazard ratio, 0.72; 95% CI, 0.53-0.97; p = 0.03). CONCLUSIONS: We observed a survival trend favoring a liberal transfusion strategy in patients with septic shock when compared with the restrictive strategy. These results went in the opposite direction of the a priori hypothesis and of other trials in the field and need to be confirmed.

BACKGROUND: Several studies have indicated that a restrictive erythrocyte transfusion strategy is as safe as a liberal one in critically ill patients, but there is no clear evidence to support the superiority of any perioperative transfusion strategy in patients with cancer. METHODS: In a randomized, controlled, parallel-group, double-blind (patients and outcome assessors) superiority trial in the intensive care unit of a tertiary oncology hospital, the authors evaluated whether a restrictive strategy of erythrocyte transfusion (transfusion when hemoglobin concentration <7 g/dl) was superior to a liberal one (transfusion when hemoglobin concentration <9 g/dl) for reducing mortality and severe clinical complications among patients having major cancer surgery. All adult patients with cancer having major abdominal surgery who required postoperative intensive care were included and randomly allocated to treatment with the liberal or the restrictive erythrocyte transfusion strategy. The primary outcome was a composite endpoint of mortality and morbidity. RESULTS: A total of 198 patients were included as follows: 101 in the restrictive group and 97 in the liberal group. The primary composite endpoint occurred in 19.6% (95% CI, 12.9 to 28.6%) of patients in the liberal-strategy group and in 35.6% (27.0 to 45.4%) of patients in the restrictive-strategy group (P = 0.012). Compared with the restrictive strategy, the liberal transfusion strategy was associated with an absolute risk reduction for the composite outcome of 16% (3.8 to 28.2%) and a number needed to treat of 6.2 (3.5 to 26.5). CONCLUSION: A liberal erythrocyte transfusion strategy with a hemoglobin trigger of 9 g/dl was associated with fewer major postoperative complications in patients having major cancer surgery compared with a restrictive strategy.

Systemic Lupus Erythematosus (SLE) is the most common systemic autoimmune disease, occurring more frequently in women, usually aged between 16 and 55 years 1, 2. Although classically the kidneys are the organs most affected in SLE, cardiopulmonary circulation and the heart may also be affected significantly 3. In this context, the occurrence of acute pulmonary edema associated with lupus myocarditis is rare and specific immunosuppressive therapy remains unclear.

O lupus eritematoso sistêmico (LES) é a mais comum das doenças auto-imunes sistêmicas, ocorrendo com maior freqüência no sexo feminino, usualmente na faixa etária entre 16 e 55 anos1,2. Embora os rins classicamente sejam os órgãos mais acometidos no LES, o coração e a circulação cardiopulmonar também podem ser afetados de forma significativa3. Nesse contexto, a ocorrência de edema agudo de pulmão associado à miocardite lúpica é rara e de tratamento imunossupressor específico ainda incerto.

O lupus eritematoso sistêmico (LES) é a mais comum das doenças auto-imunes sistêmicas. Embora os rins classicamente sejam os órgãos mais acometidos no LES, o coração também pode ser afetado de forma significativa. Entretanto, a ocorrência de edema agudo de pulmão associado à miocardite lúpica é rara e de tratamento imunossupressor específico ainda incerto. O presente relato de caso revisa a literatura quanto a manifestações lúpicas do sistema cardiopulmonar, seu diagnóstico e tratamento, e descreve uma paciente lúpica jovem que evoluiu com edema agudo de pulmão decorrente de uma miopericardite lúpica aguda. O rápido diagnóstico pôde permitir o emprego da terapêutica imunossupressora adequada com reversão completa da disfunção miocárdica. Em pacientes jovens com quadro sugestivo de edema agudo de pulmão, o diagnóstico de LES deve ser considerado. O uso de pulsoterapia com corticóide endovenoso mostrou-se eficaz e seguro para o tratamento da manifestação cardíaca extrema.
Systemic lupus erythematosus is the most common systemic autoimmune disease. Although kidneys are the mainorgans affected, heart may suffer injury too. However, acute pulmonary edema associated to lupic myocarditis is rare and its specific immunosuppressive treatment is still undefined. The present case report reviews literature about lupic manifestations in heart and lungs, their diagnosis and treatment, and describes an young lupic patient that had pulmonary edema due toacute lupic myopericarditis. Prompt diagnosis enabled correct immunosuppressive therapy that resulted in a complete reversion of myocardial disfunction. Lupus is a possible diagnosis in young patients with pulmonary edema. The use of intravenous pulse therapy with corticosteroids was safe and efficient to healing of this severe myocardial manifestation.
