Gelsolin level for evaluating severity and prognosis in patients at critically ill / 中华全科医师杂志

ABSTRACT

Objective To investigate clinical value of gelsoin level for evaluating severity and prognosis in patients with critical illness. Methods Forty-eight patients with critical illness admitted to the Emergency Intensive Care Unit of Beijing Hospital during February to December 2008 were enrolled in this study, with 23 survivors and 25 deaths. Serum level of gelsolin was measured for 31 of them at least twice during their hospital stay, and for other 17 only once at their admission. They all were evaluated with acute physiology and chronic health evaluation Ⅱ ( APACHE Ⅱ ) scores within 24 hours after admission. In addition, serum level of gelsolin was measured for another 307 healthy adults as controls. Results Initial level of gelsolin was significantly lower in 48 patients at critically ill than that in controls [(24 ± 11) mg/L vs. (192 ±39) mg/L, P < 0. 01]. There was significant difference in initial level of gelsolin between surviving group (23 cases) and death group (25 cases) [(28 ± 10) mg/L vs. (21 ±12) mg/L, P = 0. 033]. Fatality of patients at critically ill increased as their level of gelsolin at 22 mg/L or less, with a predicting accuracy of 74. 19% , as well as decreasing trend of their gelsolin levels in continuously minitoring, with a predicting accuracy of 70. 97%. Predicting accuracy of APACHE Ⅱ scores of 30 or more was 67.74%. However, predicting accuracy would reach 93.55% as final level of gelsolin and its decreasing trend combined with APACHE Ⅱ scores in prognostic assessment for critically ill patients. Conclusions Severity of patients at critically ill can be predicted by their gelsolin level, especially in continuously monitoring, which is an indicator better than APACHE Ⅱ scores. Combination of gelsolin level with APACHE Ⅱ scores shows a more accurate prognostic assessment for critically ill patients.
