Capillary permeability is a tightly regulated feature of microcirculation in all organ beds; however, in sepsis this feature is fundamentally altered. We previously reported elevated levels of vascular endothelial growth factor and its receptor ( fms ‐like tyrosine kinase‐1) in patients with septic shock, then investigated two kinds of angiopoietins in those patients. An enzyme‐linked immunoassay was used to measure serum angiopoietin‐1 and ‐2 levels in 12 patients with septic shock who were treated by direct hemoperfusion with a polymyxin B‐immobilized fiber column (DHP‐PMX). The angiopoietin‐1 level was lower in patients with septic shock (7.01 ± 10.08 ng/mL) than in controls (28.24 ± 11.61 ng/mL, P < 0.001), but the angiopoietin‐2 level was higher in septic shock patients (40.83 ± 30.13 ng/mL vs. 2.47 ± 1.78 ng/mL, P < 0.001). Between seven survivors and five non‐survivors there was no significant difference in angiopoietin‐1 levels before DHP‐PMX therapy. During DHP‐PMX therapy, however, the angiopoietin‐2 level was significantly decreased in survivors (31.52 ± 26.15 ng/mL vs. 17.32 ± 22.46 ng/mL, P = 0.035). Moreover, at the end of the therapy, the angiopoietin‐1 level was significantly lower in non‐survivors (1.14 ± 1.30 ng/mL vs. 10.43 ± 13.56 ng/mL, P = 0.042), but the angiopoietin‐2 level in non‐survivors was significantly higher (70.79 ± 40.47 ng/mL vs. 17.32 ± 22.46 ng/mL, P = 0.019). The angiopoietin‐2 level may be associated with vascular permeability in septic patients, and angiopoietins may be suitable markers of disease severity and mortality.
