title: Changes in plasma erythropoietin and interleukin-6 concentrations in patients with septic shock after hemoperfusion with polymyxin B-immobilized fiber.
abstract: OBJECTIVE
  To find out whether polymyxin B-immobilized fiber (PMX-F) treatment affects the clinical parameters and plasma concentrations of erythropoietin (EPO) and interleukin (IL)-6.
  
  
  METHODS
  A prospective case series study.
  
  
  METHODS
  Intensive care unit of the Department of Internal Medicine, Misato Junshin Hospital, Saitama, and Koto Hospital, Tokyo, Japan.
  
  
  METHODS
  17 consecutive patients (10 men, 7 women; mean age 54.6 years) with clinically defined septic shock and 20 healthy volunteers (12 men, 8 women; mean age 52.2 years).
  
  
  RESULTS
  Of the 17 patients with septic shock, 9 (53 %) survived. The systolic blood pressure increased significantly from 78+/-6 to 106+/-8 mm Hg 2 h after PMX-F treatment in patients with septic shock. Plasma endotoxin levels decreased significantly after treatment, from 40+/-6 to 12+/-4 pg/ml. The pretreatment plasma concentrations of EPO and IL-6 were significantly higher in the 8 nonsurviving patients with septic shock (EPO: 400+/-36 mlU/ml; IL-6: 6260+/-1180 pg/ml) than in the 9 surviving patients (EPO: 120+/-22 mlU/ml; IL-6: 680+/-138 pg/ml) and the 20 control subjects (EPO, 12+/-6 mlU/ml; IL-6, 8+/-2 pg/ml). Plasma concentrations of EPO and IL-6 in patients with septic shock decreased significantly after PMX-F treatment (EPO, nonsurviving: 320+/-28 mlU/ml, p < 0.05; survivors: 26+/-8 mlU/ ml, p < 0.001; IL-6, nonsurviving: 3860+/-840 pg/ml, p < 0.01; survivors: 84+/-20 pg/ml, p < 0.001).
  
  
  CONCLUSIONS
  Plasma concentrations of EPO and IL-6 may be prognostic indicators in patients with septic shock: PMX-F treatment may be effective in reducing the plasma concentrations of EPO and IL-6 in patients with septic shock.
