Additional tests: CSF Gram stain and cultures, blood cultures, CSF bacterial antigens, CSF polymerase chain reaction (PCR) for common viruses . Assessment and Diagnostic Findings. These findings are outlined in Table 10.1 below. Bacterial meningitis has a high mortality rate and characteristic effects on CSF white blood cell counts, CSF protein levels, and the CSF:serum glucose ratio. 02 months. Nonetheless, no combination of findings in CSF cells, 95% of patients with bacterial meningitis will have at least two of the following four cardinal Throbbing headache. CSF Findings in Meningitis. Condition. Consistent By analyzing a sample of cerebrospinal fluid, the lab can sometimes definitively diagnose meningitis based on CSF glucose (sugar), white blood cells, and protein levels. CSF findings: Differential: Usually neutrophilic. Viral meningitis can present similarly to bacterial meningitis but usually has a low mortality rate. CSF- culture was positive only 10 cases of bacterial meningitis while all other cases of all groups were culture negative. Cerebrospinal fluid (CSF) is an ultrafiltrate of plasma contained within the ventricles of the brain and the subarachnoid spaces of the cranium and spine. Laboratory examination of the CSF is usually the first step to confirm the presence of bacterial meningitis. Table 10-1 Typical CSF Findings in Bacterial Meningitis. Normal levels are about 2/3 the concentration of the blood glucose concentration. Report a case, suspected case, and/or positive laboratory result to the local public health department in which the patient None. The antimicrobial susceptibility tests (e.g., determinations of minimal inhibitory concentrations Serum PCT levels were significantly higher in bacter-ial meningitis group (median=2.04 (1.23.18) ng/ml) compared to non-bacterial meningitis (median=0.35 Typically, CSF findings include lymphocytic pleocytosis. Bacterial meningitis may cause a lymphocytic predominance in <10% of patients. Normal CSF may contain up to 5 WBCs per mm 3 in adults and 20 WBCs per mm 3 in newborns. In bacterial meningitis, opening pressure generally is between 200 and 500 mm H 2 O (lower in children); white blood cell count and protein concentration are The median WBC count in the CSF was 50 (IQR 18.5, 122.5) 10 6 /L, The median CSF glucose concentration was 1.66 (IQR 0.80, 2.85) mmol/L. These findings add credence to the limited body of evidence demonstrating that data from early CSF analyses prior to microbiologic workup in a cohort of adult patients with Describe expected CSF findings in normal, bacterial meningitis, and viral meningitis. Acute disseminated encephalomyelitis associated with bacterial meningitis, Confirmation of the diagnosis of bacterial meningitis comes mainly from examination and culture of CSF obtained from a lumbar puncture. Reporting Information Class B. Polk and Steele reported that seven of 261 pediatric meningitis patients had a positive CSF culture without any abnormalities on initial CSF tests. 1 While awaiting bacterial culture results, which can take up to 48 hours to return, clinicians need to make treatment decisions on the basis of the infants CSF profile. Packed cell volume. Typically, the CSF shows significant neutrophilic pleocytosis [], a decreased glucose concentration, and an elevated protein level.The absence of pleocytosis in the CSF has occasionally been described in cases of pediatric meningitis [2, 3], especially in Various diseases of the central nervous system can be diagnosed by examining CSF. specificity of 10%, positive predictive value of 81%, and negative predictive value of 3%. In our study, 47 (88.67%) cases out of 53 had quantitative level of CSF-CRP > 1000 ng/ml in bacterial meningitis patients and only 6 (11.32%) cases had <1000ng/ml. To enhance the detection of bacterial meningitis in an East Asian surveillance study, we employed cerebrospinal fluid (CSF) bacterial culture, latex agglutination (LA) and polymerase chain reactionenzyme immunoassay (PCREIA) testing for Haemophilus influenzae type b (Hib) and Streptococcus pneumoniae (Sp). Acute disseminated encephalomyelitis in adulthood occurs in most cases after a viral infection. Pediatrics. Non specific findings include CBC, biochemical profile, coagulation profile and blood culture. Although not definitive, certain CSF findings are suggestive of bacterial, viral, fungal, or tuberculous meningitis. Bacterial meningitis. 44, 50 Cell counts 2 standard deviations from the mean were generally less than 20 cells/mm 3. Typically, the CSF shows an elevated neutrophil count, elevated protein, depressed glucose, positive Gram stain, and growth of the bacteria on appropriate culture m According to Seupaul, the following 3 findings on CSF analysis have clinically useful likelihood ratios for the diagnosis of bacterial meningitis in adults [ 28] : CSF CSF glucose levels :-very low in bacterial infections Viral meningitis 1. CSF glucose. This International journal, Journal of Clinical Neuroscience publishes articles on clinical neurosurgery and neurology and the related neurosciences such as neuro-pathology, neuro-radiology, neuro-ophthalmology and neuro-physiology. 3. Condition. The ratio of glucose in CSF to that in blood is normally 0.6 (if the blood glucose is between 70 and 120 mg/dl). CSF analysis findings in different types of meningitis. Prognosis varies according to the causative organism. A predominance of neutrophils (usually >90% PMN), a markedly low CSF glucose (also termed hypoglycorrhachia), and an elevated CSF protein are seen almost Glucose levels in CSF normally reflect the levels seen in the blood. blood glucose . The clouding of the CSF ( Fig. Ihekwaba et al 2 found that enteroviruses are the leading cause of viral meningitis in the immunocompetent adult population and observed that the CSF WCC was lower than in meningitis of other viral aetiologies. Chemical properties: i. Albumin ii. BAS/CSC 7/25/02 Meningitis PLUS Key Points: The differential diagnosis for hypoglycorrhachia (low CSF glucose) is infectious (bacteria, TB, fungal), sarcoid, carcinomatous meningitis. Consistent with the findings are decreased glucose and elevated protein levels in the fluid. Normal cerebrospinal fluid (CSF) may not exclude bacterial meningitis in the early stage Grade B. IDCM Section 3: Meningitis, Bacterial. A cerebrospinalfluid (CSF) glucose level less than 1.9 mmol/L, a CSF No evidence of bacterial or fungal meningitis (i.e., no bacteria identified on Gram stain of CSF, no bacteria grown on culture of CSF) and CSF findings (cell count, protein levels, and glucose Acute disseminated encephalomyelitis in adulthood occurs in most cases after a viral infection. Summary of CSF findings In Various Diseases Cerebrospinal fluid analysis is a diagnostic of various diseases. The CSF glucose concentration is <40 mg/dL in approximately 50%-60% of patients; a ratio of CSF to serum glucose of 40.4 was 80% sensitive and 98% specific for the diagnosis of bacterial meningitis in children >2 months of age. Cerebrospinal fluid findings in aseptic versus bacterial meningitis. Meningitis Bacterial and viral encephalitis; Definitions of Orchitis, Epididymitis, Balanoposthitis. A lumbar puncture to obtain CSF is the most important investigation when a diagnosis of bacterial meningitis is suspected. There may be a 24 hour lag in the CSF level when compared to the blood level. Cerebrospinal fluid findings in patients with aseptic meningitis classically are described as elevated white blood cell counts with a predominance of. Glucose iv. The mean CSF glucose value using the conventional laboratory technique was 98.97 61.10 mg/dL, and with glucometer was 109.59 67.85 mg/dL. Logistic regression analysis was performed to understand the relationship between culture-proven bacterial meningitis with established independent variables. The analysis can also determine the type of meningitis, which can be viral, bacterial, fungal, or aseptic (unrelated to infection). CSF is a sterile fluid: Intracranial Pressure: 174 mm/H20 and a moderate to high elevation of the number and type of cells in the spinal fluid clearly indicate a bacterial meningitis. Assessment and Diagnostic Findings If the Clients with bacterial meningitis demonstrate the following: Moderately elevated CSF pressures. xanthochromic index with spectrophotometry (in SAH) extended culture (Listeria, Cryptococcus) Lumbar puncture and examination of the cerebrospinal fluid (CSF) are essential steps in the diagnosis of meningitis. In many of the infections that cause chronic meningitis, CSF contains only a few of the organisms, making identification of the cause difficult. Dexamethasone. An 82-year-old Japanese woman presented with a fever and somnolence. Meningitis can be infectious or it can be caused by injury, cancer, and other noninfectious causes. Some patients with bacterial meningitis (e.g., group BACTERIAL MENINGITIS SC(NHS)FT Implemented November 2015 Review Aug 2017 (do not use after this date) Page 200 of 511 CSF FINDINGS: Meningitis can occur in children with Objective To determine if, in the era after Haemophilus influenzae type b, the cerebrospinal fluid (CSF) white blood cell (WBC) count can be safely used to stratify children suspected of having Leukocytes (usually Bacterial meningitis. serum glucose, renal and liver function, and testing for HIV. Thus, diagnosis of subacute or chronic meningitis based on CSF findings may require multiple large samples over time, particularly for cultures. One hallmark of bacterial meningitis is reduced glucose levels in the cerebrospinal fluid (CSF) of patients, which allows a physician to quickly begin appropriate Report a case, suspected case, and/or positive laboratory result to the local public health department in which the patient resides by the close of the next business day.If patient residence is unknown, report to the local public health department in which the reporting healthcare provider or laboratory is located. They were grouped as bacterial meningitis on the basis of other clinical features and CSF findings like leukocytosis with neutrophilic predominance, decreased glucose and/or elevated protein. Viral meningitis. Note that cytological examination should precede centrifugation and heating of the Bile pigments v. Bile salts. Abstract. Opening pressure 48 mmHg. Decreased CSF glucose level (normal, 60 to 80 mg/dl, or two thirds of the serum glucose value) Bacterial meningitis alters intracranial 237 A lack of CSF pleocytosis can also be seen in 22% of patients with documented neurosyphilis. CSF 3 shows viral meningitis. Here, I summarise three key papers looking at this very question do antibiotics affect cerebrospinal fluid (CSF) results in bacterial meningitis? 6 Eighty-seven percent of patients with bacterial meningitis will have a WBC count higher than -Typical CSF findings in bacterial meningitis: WBC count >1000 with predominance of neutrophils; high protein (ranges from 100-500 mg/dL), low glucose (often <40 mg/dL), high opening One hallmark of bacterial meningitis is reduced glucose levels in the cerebrospinal fluid (CSF) of patients, which allows a physician to quickly begin appropriate antibiotic The CSF findings expected in bacterial, viral, and fungal meningitis are listed in the chart: Expected CSF findings in bacterial versus viral versus fungal meningitis. Consecutive infusion of G-CSF for 5 days increased the MNC concentration in peripheral blood up to 9 confirming the diagnosis of bacterial meningitis Inspection may reveal frank bleeding or dura leak of CSF (will test glucose-positive), requiring prompt intervention SC046319) promoting awareness of cerebrospinal fluid (CSF) leaks, with a particular focus on spinal CSF leaks Fix CSF glucose values are normally 50-70% of blood glucose values, therefore, use of a CSF/serum glucose ratio can correct for a decreased CSF glucose value masked by hyperglycemia. CT findings that prohibit LP: Midline shift CSF glucose levels increase and protein levels decrease. In viral meningitis there is a normal or mildly lowered ratio of CSF:blood glucose. Regardless of the CRP and white blood cell count, if no CSF is available for examination or if the CSF findings are uninterpretable, manage as if the diagnosis of meningitis is confirmed. BAS/CSC 7/25/02 Meningitis PLUS Key Points: The differential diagnosis for hypoglycorrhachia (low CSF glucose) is infectious (bacteria, TB, fungal), sarcoid, carcinomatous meningitis. New neuroimaging findings suggestive of encephalitis. CSF WBC, protein and glucose values significantly differed between subjects with culture proven bacterial meningitis vs. the remainder of CSF glucose. Current physical findings. The following findings on analysis of cerebrospinal fluid (CSF) predict a bacterial rather than a viral cause of meningitis with at least 99% certainty: a leukocyte count of at least Viral and bacterial meningitis have similar symptoms, including a fever, headache, neck stiffness, Viral meningitis is most common type, accounting for 54.6% of cases. The Gram stain is positive in >60% of cases, and culture in >80%. Infectious meningitis can be caused by a bacterial, viral, or fungal infection. Meningitis can be caused by a bacterial, fungal or viral infection. Not all cases of bacterial meningitis have typical CSF findings, and some values, particularly glucose concentration, need to be interpreted within the clinical context. Clear CSF, decreased WBC, elevated protein and elevated glucose. Levels of glucose in the cerebrospinal fluid (CSF) are used to discriminate bacterial meningitis from viral meningitis. 3 ) is caused by an increase in protein content. 0.5 to 3 g/L. specificity of 10%, The CSF contained 2976 cells/L (94% granulocytes, no malignant cells), the protein level was 1.07 g/L, and the CSF glucose level was less than 40% of the serum glucose level. Findings include a mononuclear pleocytosis (>10 cells/mm 3 in most patients), elevated CSF protein concentrations (78% of patients), and mild decreases in CSF glucose concentrations (<50 mg/dL in 55% of patients). Negrini B, Kelleher KJ, Wald ER. In general, CSF glucose levels ( half the serum glucose levels are consistent with bacterial meningitis, due to a general disturbance of the blood brain barrier (NOT BACTERIAL CONSUMPTION OF GLUCOSE). Classic findings in the CSF indicating bacterial meningitis are a pleocytosis of mostly polymorphonuclear leukocytes > 1000/l, a low CSF-serum glucose index < 0,3 or an increase in CSF lactate, and an elevated protein concentration (> 100 mg/dl) .
