Objectivethe aim of the present study was to determine whether serum neopterin and soluble interleukin (IL)-2 receptor levels were related to the development of septic shock and whether polymyxin B-immobilized fibre (PMX-F) treatment affects these levels.Methodswe examined 24 patients admitted to our intensive care unit with Gram-negative septic shock. Serum neopterin and soluble IL-2 receptor levels were measured using commercially available test kits. Patients were treated with direct hemoperfusion using PMX-F columns.Resultsfifteen out of 24 patients (63%) survived and were discharged from our hospitals within 30 days after PMX-F treatment. Blood endotoxin levels decreased significantly from 49.2+/-8.6 pg/ml to 13.2+/-4.4 pg/ml after PMX-F treatment. The pretreatment serum concentrations of neopterin and IL-2 receptor were significantly higher in the nine non-surviving patients with septic shock than in the 15 surviving patients (P<0.01) and 20 control subjects (P<0.001). Serum concentrations of neopterin and IL-2 receptor in patients with septic shock decreased significantly after PMX-F treatment (P<0.01).Conclusionsthese data suggest that serum neopterin and IL-2 receptor concentrations may be prognostic indicators in patients with septic shock. PMX-F treatment may be effective for reducing serum neopterin and IL-2 receptor concentrations.
