Biochemical parameters of cerebrospinal fluid in patients with acute viralmeningitis and meningoencephalitis

Abstract

The aim. Determination of the diagnostic value of lactate, lactate dehydrogenase, cholinesterase, acid phosphatase and cholinesterase in CSF for early diagnosis and prognosis of acute viral meningitis and meningoencephalitis. Materials and methods. 92 patients with a confirmed viral etiology of the disease were examined. Among them – 20 patients with HSV 1,2 neuroinfection, 19 patients with EBV, 15 with VZV, 14 with HHV-6 and 24 patients with enterovirus neuroinfection. Patients were divided into groups depending on the etiology and severity of the disease. In addition to analyzing the clinical course of the disease, we conducted a CSF study to determine the level of lactate, lactate dehydrogenase, creatinine kinase, cholinesterase and acid phosphatase on admission to hospital and after 10-12 days of treatment. Results of the study. The highest mean age was observed in patients with VZV meningitis – 38.27±18.24 years, the youngest were patients with enterovirus infection – 24.05±5.72 (р˂0.001). The number of women and men was the same in almost all groups, but among patients with HSV 1, 2 neuroinfection women were significantly prevalent – 16 (80 %) out of 20 cases. The most severe course was observed in groups of EBV and HHV-6 neuroinfections. Neuroinfections of enterovirus etiology had the most favorable course. The obtained data indicate the dependence of the levels of indicators, which were determined primarily from the severity of the disease. So the level of creatinine kinase and acid phosphatase in patients with moderate severity was significantly higher in comparison with severe patients (p<0.05). The lactate level was higher in patients with severe neuroinfection (p<0.05). The highest levels of lactate were detected in patients with HHV-6 meningoencephalitis (p<0.05). The level of cholinesterase was significantly lower in severe patients. Conclusions. The obtained data confirm the presence of deep metabolic disturbances in the brain tissues in all patients with acute viral neuroinfections both at the onset of the disease and in the dynamics of treatment. Determination of levels of creatinine kinase, acid phosphatase, lactate and cholinesterase in CSF of patients with acute viral neuroinfection has a high diagnostic value, but cannot be used to predict an unfavorable course of the disease
