Multivariate analysis of 9 disease-associated variables for outcome prediction in patients with sepsis.

OBJECTIVE: To assess the ability of 9 clinical or biological variables to predict outcome (survival or nonsurvival) using multiple regression and classification analyses. DESIGN: Prospective, descriptive cohort study with no interventions. SETTING: Surgical intensive care unit of a tertiary care hospital and a medical school research laboratory. PATIENTS: Eighteen patients with a documented source of infection who met currently accepted criteria for sepsis syndrome or septic shock. MAIN OUTCOME MEASURES: Prediction of survival or nonsurvival based on analysis of clinical (Multiple Organ Dysfunction score, Acute Physiology and Chronic Health Evaluation III scores) and biological (plasma levels of cortisol, interleukin 6, interleukin 10, phospholipase A2, soluble tumor necrosis factor receptor p75, and monocyte membrane tumor necrosis factor receptor levels) variables, with comparison of predicted and actual outcomes. RESULTS: Plasma interleukin 6, interleukin 10, and phospholipase A2 concentrations were not significantly (P>.05) different between survivors and nonsurvivors. By standard, forward stepwise, and backward stepwise multiple regression analyses, only monocyte membrane tumor necrosis factor receptor levels measured at the onset of sepsis significantly predicted outcome in all 3 analyses. However, by both standard and backward stepwise analyses, Multiple Organ Dysfunction scores based on evaluation at the onset of sepsis and 24 hours later were also significant predictors of outcome. Classification analysis showed that assignment to outcome group was statistically significant when based on monocyte membrane tumor necrosis factor receptor levels determined at the onset of sepsis or on Multiple Organ Dysfunction scores assessed 24 hours after sepsis was diagnosed. CONCLUSION: Although these findings were based on a relatively small cohort, both multiple regression and classification analyses indicated that only monocyte membrane tumor necrosis factor receptor levels are able to discriminate survivors from nonsurvivors at the onset of sepsis.

[Pulmonary lymph node in acute juvenile paracoccidioidomycosis (a case report)]. / Linfonodo pulmonar na paracoccidioidomicose aguda infantil (relato de um caso).

The primary complex like Ghon was observed in a child's clinical roentgenographic study. C.S., white, male, 6 years old, was born in Curitiba (PR), Brazil and living in Guaratingueta (SP), Brazil, developed "common cold", bimodal diary fever, chills, shake and sweats. Dyspnea, cough with general lymphadenopathy. Foot and right shoulder arthralgias. Six months ago visited a cave, equitation practice, dog and cat contacts and no transfusion, frontal sweats, fever (38.4 degrees C). T.A. was 8/6, tachycardia in generalized lymphadenopathy. Cardiopulmonary system was normal, mesogastric tumoral mass, hepatosplenomegaly and no ascites. Bone marrow with eosinophilia; nodule demonstrated presence of P. brasiliensis, hypoalbuminemia; hyperglobulinemia; anemia; leukocytosis with eosinophilia. Immunodiffusion with exoantigen 43 kd of P. brasiliensis was 1/32. Primary complex like Ghon was observed in interstitial pneumonia followed by mediastinal and mesogastric mass (35 to 40 days). Clavicular osteolytic lesions (45 to 60 days) appeared during paracoccidioidomycosis therapy. Recovery was observed 2 months after treatment of acute infantile paracoccidioidomycosis.
