Abstract:
Objective To investigate the diversify and clinical significance of tumour necrosis factor-alpha (TNF-α), immune globulin (Ig), adenosine deaminase (ADA) in cercbrospinal fluid (CSF) of patients with intracranial infection. Method The levels of TNF-α,Ig and ADA in CSF of 25 cases of purulent meningitis ,30 eases of cerebral tuberculosis ,28 cases of virus meningitis and 24 cases of controls were detected by ELISA, immunity velocity scattering nepbelometry and enzyme coupling method respectively. Results The levels of IgA, IgM, IgG, ADA, TNF-α were (41.72±11.31) mg/L(18.11± 2.62)mg/L, (181.60±41.19)mg/L, (13.41±3.42)U/L, (418.62±43.16)ng/L in cerebral tuberculosis patients. The levels of IgA, IgM, IgG, ADA and TNF-αwere (20.65±8.85)mg/L, (93.20±4.30)mg/L, (92.77±35.09)mg/L, (3.32±2.41) U/L, (476.93±45.16) ng/L in purulent meningitis patients, and those were (7.11±2.23)rag/L,(5.81±1.19)mg/L,(20.71±10. 54)mg/L,(2. 36±0. 44)U/L,(375.06±45.21) ng/L in virus meningitis patients. The levels of IgM,IgG and IgA in cerebral tuberculosis patients and purulent meningitis patients were significantly higher than those in virus meningitis patients and controls (P< 0.01). The levels of IgG,IgA heightened most markedly in cerebral tuberculosis patients. The activity of ADA in cerebra] tuberculosis patients was higher markedly than that in controls and the other patients(P< 0.01). The levels of TNF-α in purulent meningitis patients were higher than those in controls and virus meningitis patients(P< 0.05). The levels of TNF-α in purulent meningitis patients were the highest, and the next was in cerebral tuberculosis patients. But there was no significant difference of each index between viral meningitis patients and controls. Conclusions Detecting the activity of ADA in CSF is the most valuable in diagnosing cerebral tuberculosis. Synchronized detection of TNF-α,Ig, ADA may be have better clinical application in diagnosing intracranial infection.
