ABSTRACT
We studied the incidence of decreased red blood cell deformability (RBCD) in sepsis and the association between decreased RBCD and oxygen free radical generation (as measured by malonyldialdehyde) and the occurrence of multiple-system organ failure (MSOF). Patients were divided into three groups septic (n = 28), nonseptic (n = 15), and control (n = 5). Serial measurements of deformability index, malonyldialdehyde, and MSOF were made. The deformability index for the septic group (0.23 +/- 0.17) was significantly less than that for the nonseptic (1.12 +/- 0.48) and control (1.11 +/- 0.25) groups. The malonyldialdehyde levels for the septic group (4.5 +/- 1.0 nmol/mL) were significantly greater than those for the nonseptic (2.7 +/- 0.9 nmol/mL) and control (2.6 +/- 0.8 nmol/mL) groups. The MSOF index for the septic group (10.1 +/- 2.5) was significantly greater than that for the nonseptic (7.6 +/- 1.7) and control (6.0 +/- 0.0) groups. An inverse correlation existed between malonyldialdehyde and deformability index ( = .501, less than .001, n = 40) and between deformability index and MSOF index (= .350, less than .05, n = 61). We conclude that RBCD is decreased during human sepsis; free radicals generated during sepsis may play a role in the decrease in RBCD. Decreased RBCD may contribute to the MSOF that occurs during sepsis.
