Abstract:
Objective To compare the differences in the levels of lactate dehydrogenase(LDH),creatine kinase(CK),and neuron-specific enolase(NSE)in the cerebrospinal fluid(CSF)between the patients with purulent meningitis(PM)and those with tuberculous meningitis(TBM)and evaluate the utility of the three biomarkers in the differentiation of PM and TBM.Methods Thirty-five PM patients and 45 TBM patients who attended the Department of Neurology from December 2019 to December 2021 were enrolled in this study.The CSF samples were collected from the patients before treatment.The levels of LDH,CK,NSE,and glucose,protein,and chloride in CSF were measured and compared between PM and TBM patients.The correlation between the biomarkers in CSF was analyzed by Pearson correlation coefficient.Linear regression analysis was performed to analyze the risk factors for the occurrence of TBM.Receiver operating characteristic(ROC)curves were plotted to evaluate the discriminative value of CSF LDH,CK,NSE alone or in combination in differential diagnosis of PM and TBM.Results Patient age,gender,clinical features such as fever,pathological signs,vomiting,limb twitching,and CSF levels of glucose and protein did not show significant difference between TBM patients and PM patients(P＞0.05).TBM was associated with significantly higher LDH and NSE levels in CSF and significantly lower CK level and chloride in CSF compared to PM(P＜0.05).Pearson correlation analysis showed that LDH level in CSF was negatively correlated with CK and chloride(r＜0,P＜0.05),and positively correlated with NSE(r＞0,P＜0.05).CK was negatively correlated with NSE(r＜0,P＜0.05),and positively correlated with chloride(r＞0,P＜0.05).NSE was negatively correlated with chloride(r＜0,P＜0.05).Linear regression analysis showed that LDH,CK,NSE,and chloride levels in CSF were all associated with the occurrence of TBM(P＜0.05).ROC curves demonstrated that the AUCs of CSF levels of LDH,CK,NSE alone and in combination for differentiation between PM and TBM were 0.849(95％CI:0.768-0.930),0.858(95％CI:0.779-0.937),0.851(95％CI:0.771-0.931),and 0.954(95％CI:0.911-0.996),respectively.Conclusions The clinical features are similar for PM and TBM patients.However,the levels of LDH,CK,and NSE in CSF are different between PM and TBM.LDH,CK,NSE in combination may improve the differential diagnosis between PM and TBM.
