Predictive value of cholinesterase in the prognosis of gerontal patients with systemic inflammatory response syndrome

Objective To explore the predictive value of cholinesterase (ChE) in the prognosis of gerontal patients with systemic inflammatory response syndrome. Methods The clinical data of 124 elderly patients with systemic inflammatory response syndrome collected from September 2009 through September 2010 were retrospectively analyzed. All patients were divided into death group and survival group according to the outcome of patients. The cholinesterase ( ChE), albumin, D-Dime, lactic acid and C-reactive protein (CRP) were detected, and the APACHE Ⅱ and GCS scores were documented in the first 24 hours in the ICU. Results There were no significant differences in age, gender, APACHE Ⅱ score and GCS score of patients between death group and survival group ( all P ＞ 0. 05 ), but there were significant differences in lactic acid, D-Dime, albumin, CRP and ChE between two groups ( theP values were 0.011,0.011, 0. 007,0. 008, 0. 000, respectively) . The results of multiple factors regression analysis showed that age, gender,lactic acid, D-Dime, albumin, CRP, APACHE Ⅱ score, and GCS score were not the independent risk factors of prognosis of gerontal patients with SIRS ( the P = 0. 401, 0. 165, 0. 446, 0. 841,0. 615, 0. 120,0. 502, 0. 184, respectively) except ChE ( P = 0. 000) . The receiver operating characteristic curve (ROC) of ChE in the gerontal patients with SIRS showed the area under curve (AUC) = 0.797, SE =0.04, P=0. 000, and the ChE = 103.00 U/L could be a diagnosis point with sensitivity = 0.793, 1-specificity = 0. 258. The correlation analysis showed that the APACHE Ⅱ score, CRP, and albumin were poorly correlated with ChE ( Kendall coefficients were 0. 061, 0. 231, and -0. 090, and theP = 0. 161,0. 000, and 0. 069, respectively ) . Conclusions ChE maybe played a important role in the gerontal patients with SIRS, and could be a predictive index for the prognosis of gerontal patients with systemic inflammatory response syndrome.
