    ABSTRACT: OBJECTIVE: This study was performed to investigate the association of red cell distribution width (RDW) with 28-day mortality in patients with severe sepsis and septic shock. METHODS: We performed a retrospective analysis of patients with severe sepsis and septic shock. Patients' demographic data, comorbidities, the blood test results including RDW at admission to the emergency department, and Acute Physiologic and Chronic Health Evaluation II score were compared between 28-day survivors and nonsurvivors. Red cell distribution width was categorized into tertiles as 14% or less, 14.1% to 15.7%, and 15.8% or greater. Multivariate Cox proportional hazards regression analysis was performed to determine the risk factors for mortality. RESULTS: A total of 566 patients were included, and overall mortality was 29%. Red cell distribution width was significantly higher in nonsurvivors than in survivors, and the corresponding mortality of patients with an RDW of 14% or less, 14.1% to 15.7%, and 15.8% or greater was 13.1%, 30.1%, and 44.9%, respectively (P < .001). In Cox proportional hazards analysis, groups with higher RDW are independently associated with 28-day mortality compared with groups with an RDW of 14.0% or less: RDW 14.1% to 15.7% (hazard ratio, 1.66; 95% confidence interval [CI], 1.00-2.76) and RDW of 15.8% or greater (hazard ratio, 2.57; 95% CI, 1.53-4.34). The area under the receiver operating curve of RDW was 0.68 (95% CI, 0.63-0.72). CONCLUSION: Red cell distribution width is associated with 28-day mortality in patients with severe sepsis and septic shock.

    ABSTRACT: OBJECTIVE: This study was performed to evaluate whether heart-type fatty acid-binding protein (H-FABP) could predict 28-day mortality in patients with severe sepsis and septic shock. METHODS: We performed a prospective observational study and included consecutive patients with severe sepsis and septic shock. Patients' demographic data, Acute Physiology and Chronic Health Evaluation (APACHE) II score, and the blood test results including H-FABP concentrations were compared between the 28-day survivors and nonsurvivors. The association between the concentration of H-FABP and survival was analyzed with multivariate logistic regression and Cox proportional hazards regression analyses. The prognostic performance of H-FABP was compared with those of the APACHE II score and albumin using the area under the receiver operating characteristic curve. RESULTS: Of the 99 patients, 38 (38%) died. The mortality rate increased with increasing H-FABP concentration. In multivariate logistic regression analyses, H-FABP greater than 40 ng/mL was an independent predictor of mortality compared with H-FABP less than 7 ng/mL (odds ratios, 9.23; 95% confidence interval, 1.29-65.86). By Cox proportional hazards analysis, H-FABP greater than 40 ng/mL was associated with a 5.57-fold increased risk for death during the 28-day follow-up period (hazard ratio, 5.57; 95% confidence interval, 1.20-25.80). The area under the receiver operating characteristic curve of H-FABP was 0.739 (95% confidence interval, 0.640-0.839), which was comparable with those of the APACHE II score and albumin. CONCLUSION: The H-FABP was an independent prognostic factor and could be a useful biomarker for 28-day mortality in patients with severe sepsis and septic shock.
