To investigate the role of lipidperoxidation and infection during acute sepsis we measured antoantibodies against oxidated LDL (oLAb) and procalcitonin (PCT) comparing the neopterin as a marker of macrophages activation and CRP as marker of inflammation.
A prospective, descriptive cohort study.
23 patients admitted to the ICU with verified sepsis (n=12, s=6) or SIRS (n=11, s = 6).
Measurements and results
The clinical severity of the disease was asessed using the APACHE II score over a period of 24 h after admission. Determination of serum levels of all parameters under study was performed on daily drawn serum samples. Surviving septic patients produced significantly increasing oLAbs (P < 0.001) as significantly decreasing PCT levels (P < 0.001). In contrast, in non-survivors oLAbs were decreasing (P < 0.05) and PCT levels were increasing (P < 0.05).
The identical effect was found for the SIRS group with the exception, that the significance of PCT in survivors was slightly lower (P < 0.05).
Despite both patient groups were rather small, we consider that the measurement of oLAb as well as PCT to be a useful prognostic marker concerning the outcome of sepsis as well as of SIRS patients.
