Description for medicine or protocol of treatment in detail:

 

纳入标准:

1. 符合中枢神经系统感染的症状或体征(一项或多项):发热、头痛、呕吐、痫性发作、局灶性神经功能损害、精神行为异常、意识障碍、脑膜刺激征等; 2. 年龄>=18岁; 3. 完善腰椎穿刺且成功获取足量的脑脊液; 4. 至少满足以下条件之一:a.颅内压增高(>200mmH2O);b.脑脊液白细胞计数增加(>5×106/L);c.脑脊液蛋白增高(>0.45g/L);d.脑脊液葡萄糖水平降低(<2.25mmol/L或同步血糖的1/2);e.脑脊液氯化物含量降低(<120mmol/L);f.全血细胞计数显示白细胞>10×109/L,中性粒细胞比例>80%;g.脑影像学检查提示感染可能;h.不满足上述7项条件中的任意一项,但经验性抗感染治疗有效。

Inclusion criteria

1. Presence of symptoms or signs consistent with central nervous system infection (one or more): fever, headache, vomiting, seizures, focal neurological deficits, behavioral abnormalities, impaired consciousness, meningeal irritation signs, etc.; 2. Age>=18 years; 3. Completion of lumbar puncture with successful collection of sufficient cerebrospinal fluid (CSF); 4. Fulfillment of at least one of the following criteria: a. Elevated intracranial pressure (>200 mmH?O); b. Increased CSF white blood cell count (>5 × 10?/L); c. Elevated CSF protein level (>0.45 g/L); d. Decreased CSF glucose level (<2.25 mmol/L or less than half of the simultaneous blood glucose level); e. Decreased CSF chloride level (<120 mmol/L); f. Complete blood count showing white blood cells >10 × 10?/L with neutrophil proportion >80%; g. Neuroimaging suggestive of possible infection; h. Failure to meet any of the above seven criteria, but effective response to empirical anti-infection therapy.

排除标准:

1. 患者拒绝腰椎穿刺或存在腰椎穿刺禁忌证或获取的脑脊液过少; 2. 确诊其他系统感染性疾病或中枢神经系统非感染性疾病(自身免疫性脑炎、肿瘤、中枢神经系统血管性疾病等); 3. 临床信息严重缺失; 4.最终诊断未明确且经验性抗感染治疗效果欠佳。

Exclusion criteria:

1. Patient refusal of lumbar puncture, presence of contraindications to lumbar puncture, or insufficient cerebrospinal fluid (CSF) obtained; 2. Confirmed diagnosis of infectious diseases in other systems or non-infectious central nervous system diseases (e.g., autoimmune encephalitis, tumors, cerebrovascular disorders, etc.); 3. Severely incomplete clinical information; 4. Final diagnosis not confirmed with poor response to empirical anti-infection therapy.
