NOTE: High White Blood Cell (WBC) count in the cerebrospinal fluid (CSF) (especially neutrophils), high protein level, and low glucose level should suggest the diagnosis of bacterial meningitis, though some viral pathogens may present with similar CSF profiles. Specific Risk Factors. Treatment Treatment for viral meningitis is mostly supportive. CSF protein, glucose, gram stain, cultures, wbc, leukocytes. (Meningococcal meningitis) Introduction. However, normal CSF analysis with viral meningitis -despite being rare- has been reported especially with bacterial causes. In the absence of a lumbar puncture, viral and bacterial meningitis cannot be differentiated with certainty, and all suspected cases should therefore be referred. Viral meningitis characteristically has a CSF mononuclear pleocytosis, although there may initially be a neutrophilic predominance. Adjunctive tests such as CSF lactate measurement, latex agglutination, and polymerase chain reaction testing can help differentiate between bacterial and viral causes of meningitis. As for the findings of viral meningitis. 5, 19. Prospective investigation of a large outbreak of meningitis due to Echovirus 30 during summer 2000 in Marseilles, France. [32] Bernit BE, de Lamballerie X, Zandotti C, et al. CSF testing is performed to evaluate the level or concentration of different substances and cells in CSF in order to diagnose conditions affecting the brain and spinal cord (central nervous system). A CSF analysis is a group of tests that evaluate substances in CSF in order to diagnose conditions affecting the brain and spinal cord (central nervous system). The gold standard for diagnosing meningitis is a cerebrospinal fluid (CSF) test. Antimicrobial guidelines. Analysis of cerebrospinal fluid obtained via lumbar puncture provides a definitive diagnosis. Cerebrospinal fluid (CSF) analysis, including cell count and differential, glucose, protein, culture, and molecular diagnostics as available, should be performed. At our institution, this panel tests for E coli, Haemophilus influenza, L monocytogenes, N . 24 In addition, 10% of cases have a lymphocytic predominance. 13 A CSF-PCR panel identifies common pathogens associated with meningitis from 1 mL of CSF and is useful in identifying the etiologic agent within hours. Herpes virus simplex viral meningitis - usually caused by HSV-2 >> HSV-1 8. Meningitis can be community acquired or hospital acquired and caused by various micro organisms ranging from bacteria, virus, fungus, protozoa, etc. CSF analysis should include a gram stain, acid-fast stain, and culture to further aid in diagnosis. In patients with bacterial meningitis, CSF culture and sensitivity is the most Aims and objectives reliable method, which is positive in 30 - 60% cases only 1. Value of repeat lumbar puncture in the differential diagnosis of meningitis. . Plus..just to complicate matters..prolonged high pressure can eventually cause a spinal leak as the body tries to protect the brain from permanent damage. ME panel is an aid for the diagnosis of specific agents of meningitis and/or encephalitis and results are . Keywords: antibiotics, cerebrospinal fluid, children, meningitis, PCR Background Globally, preventableinfectious diseasesareacommon cause of [1] The diagnosis of viral meningitis is made by clinical history, physical exam, and several diagnostic tests. The gold standard tool for diagnosis of viral meningitis is the polymerase chain reaction (PCR), which detects and quantifies viral DNA or RNA in the patient's CSF . For viral infection of the brain parenchyma, please refer to the . Negrini B, Kelleher KJ, Wald ER. Rotbart HA. The classic symptoms of viral meningitis—sudden onset of fever, stiff neck, and altered mental status—are indistinguishable from those of bacterial meningitis. The meningitis. Cerebrospinal Fluid Analysis. Diagnosis . However, anyone with symptoms of meningitis should see a doctor right away because any type of meningitis can be serious. Tuberculous meningitis is difficult to differentiate from meningitis caused by other pathogens. Although the glucose concentration is typically normal, it can be below normal in meningitis from . A meta-analysis of 25 studies found that, as a single marker, CSF lactate concentration had better diagnostic accuracy in distinguishing bacterial from aseptic meningitis when compared to CSF glucose, CSF/plasma glucose quotient, CSF protein, and CSF total number of leukocytes. What is it used for? Patients and methods A cross-sectional study was carried out in . This guideline aims to help with the interpretation of CSF results for the purpose of diagnosing or excluding meningitis. The patient's specific factors (which are beyond the scope . Definition. H Influenzae: (3%) - Head trauma with CSF leak, otitis . Cerebrospinal fluid pleocytosis (>5 lymphocytes/mm 3) is present in >95% cases of acute viral encephalitis. The need for rapid and accurate diagnosis is mandatory for improving the outcome. Cerebrospinal fluid (CSF) analysis is a known and popular standard for diagnosing bacterial meningitis, along with biomarkers like Creactive protein and white blood cell count. Viral meningitis. The CSF findings are more suggestive of viral meningitis given the clear appearance of the CSF, the mildly raised WCC (consisting mainly of lymphocytes), raised protein level and normal glucose. It usually lists the blood cells and determines which cells in the white blood cell line dominate. Meningococcal disease. Background Meningitis is one of the most dangerous infection affecting children. In the early stages of acute bacterial and viral meningitis, the signs and symptoms are often nonspecific and it is not always possible to make a differential diagnosis. Findings include headache, fever, and nuchal rigidity. Here, the authors combine metagenomics-based pathogen detection in cerebrospinal fluid with a host . 13 In very early presentations of viral meningitis, there may be a neutrophilic predominance, which typically becomes . Bacterial meningitis can present with counts significantly lower than 1000 cells/μL, and rare cases with normal counts on initial CSF analysis have been described. infection (bacterial, viral, and fungal) autoimmune disease. Cerebrospinal fluid (CSF) analysis - Meningitis. diagnosis and appropriate medica l and/or surgical management strategies to optimize the outcome (Raman Sharma, 2010). CSF analysis in Viral meningitis usually reveals lymphocytic pleocytosis. Gram stain is negative. Viral meningitis is inflammation of the layers of tissue that cover the brain and spinal cord (meninges) and of the fluid-filled space between the meninges (subarachnoid space) when it is caused by viruses.
