结核性脑膜炎不同时期脑脊液细胞学的特点观察及意义 总被引:4,自引:0,他引:4
结核性脑膜炎近年来有增多趋势,由于该疾病临床表现的变异,往往难以确诊。据文献报导,脑脊液(CSF)抗酸染色镜检查到结核菌仅为15%~30%1。动用酶链聚合反应(PCR)2方法检测,虽检出率较高,但由于受该方法学条件限制,目前一般实验室还不能普遍应用。本文参照候氏微型沉淀室法对45例结脑患者CSF作细胞学检查,发现结脑在不同时期其白细胞出现率呈现一定的特征,可协助对结脑作出早期诊断,观察病情及判断预后,现将有关资料报道如下。 1 材料和方法 1.1 病例和标本 为近三年来我院神经科就诊患者,计45例,经临床确诊… 相似文献

Objectives: To determine whether ancillary tests of cerebrospinal fluid (CSF), specifically, the total protein concentration, glucose concentration, and percent neutrophils, provide information for diagnosing acute bacterial meningitis among children with low white blood cell (WBC) count in CSF. Methods: The authors retrospectively reviewed CSF from children aged 1 month to 18 years undergoing lumbar puncture at Children's Hospital in Boston from 1993 to 1999. Data were supplemented with CSF test results obtained from children with 0–30 WBCs/mm3 in CSF diagnosed with acute bacterial meningitis at the same institution from 1984 to 1992. For each test, the incremental value of ancillary tests was estimated by calculating indices of performance such as the area under receiver operator characteristic curves (AUC) and interval likelihood ratios that are relatively insensitive to disease prevalence. Results: Among children with 0–30 WBCs/mm3 in CSF who met study criteria, acute bacterial meningitis was identified in ten of 7,701 (0.1%) for the period from 1993 to 1999 and supplemented with 11 additional cases for the period from 1984 to 1992. AUC values for ancillary tests were 0.61 for total protein concentration, 0.69 for glucose concentration, and 0.90 for percent neutrophils. Interval likelihood ratios were unremarkable for mildly abnormal test results. In contrast, interval likelihood ratios for markedly abnormal test results were higher: 22 for total protein concentration >120 mg/dL, 57 for neutrophils >75%, 15 for glucose concentration <20 mg/dL, and 20 for glucose concentration >120 mg/dL. Conclusions: When markedly abnormal, results of CSF total protein concentration, glucose concentration, and percent neutrophils have value for diagnosing acute bacterial meningitis, even among children with a low WBC count in CSF. 相似文献

A Decision Rule for Predicting Bacterial Meningitis in Children with Cerebrospinal Fluid Pleocytosis When Gram Stain Is Negative or Unavailable 总被引:1,自引:0,他引:1
Bema K. Bonsu MBChB Henry W. Ortega MD Mario J. Marcon PhD Marvin B. Harper MD 《Academic emergency medicine》2008,15(5):437-444
Objectives: Among children with cerebrospinal fluid (CSF) pleocytosis, the task of separating aseptic from bacterial meningitis is hampered when the CSF Gram stain result is unavailable, delayed, or negative. In this study, the authors derive and validate a clinical decision rule for use in this setting.
Methods: This was a review of peripheral blood and CSF test results from 78 children (<19 years) presenting to Children's Hospital Columbus from 1998 to 2002. For those with a CSF leukocyte count of >7/μL, a rule was created for separating bacterial from viral meningitis that was based on routine laboratory tests, but excluded Gram stain. The rule was validated in 158 subjects seen at the same site (Columbus, 2002–2004) and in 871 subjects selected from a separate site (Boston, 1993–1999).
Results: One point each (maximum, 6 points) was assigned for leukocytes >597/μL, neutrophils >74%, glucose <38 mg/dL, and protein >97 mg/dL in CSF and for leukocytes >17,000/mL and bands to neutrophils >11% in peripheral blood. Areas under receiver-operator-characteristic curves (AROCs) for the resultant score were 0.98 for the derivation set and 0.90 and 0.97, respectively, for validation sets from Columbus and Boston. Sensitivity and specificity pairs for the Boston data set were 100 and 44%, respectively, at a score of 0 and 97 and 81% at a score of 1. Likelihood ratios (LRs) increased from 0 at a score of 0 to 40 at a score of ≥4.
Conclusions: Among children with CSF pleocytosis, a prediction score based on common tests of CSF and peripheral blood and intended for children with unavailable, negative, or delayed CSF Gram stain results has value for diagnosing bacterial meningitis. 相似文献
