Background: Analysis of cerebrospinal fluid is gold standard for diagnosis of meningitis. There is considerable difficulty in interpreting laboratory finding after prior antibiotic therapy. This study was conducted to evaluate the effect of intravenous antibiotic administration before lumbar puncture on cerebrospinal fluid profiles in children with bacterial meningitis. Methods: A hospital based retrospective study carried out using the data retrieved from the medical record department of Manipal Teaching Hospital Pokhara, Nepal; from 1st July 2006 to 31st July 2011. Clinical findings and relevant investigations were entered in a predesigned proforma. Patients were divided in two different groups as bacterial meningitis with and without prior intravenous antibiotic therapy. Various laboratory parameters including CSF were compared between these two groups using the statistical software, SPSS version 18.0. Results: A total of 114 children were included in this study among which 49(43%) children had received intravenous antibiotics before lumbar puncture. Mean CSF WBC count was(267.6± 211 vs. 208.1±125.3.3) and protein level (114.1±65.9 vs. 98.3±37.7mg/dl) in untreated vs. pretreated groups respectively. Neutrophil percentage was decreased (57.1±28.1vs.72.9±18.9) with higher CSF sugar level (43.3±11.8 vs. 51.2±13.2) after prior antibiotics therapy (p<0.001). Conclusion: Antibiotic pretreatment was associated with higher cerebrospinal fluid glucose levels with decreased neutrophils and increased lymphocytes. Pretreatment did not modify total cerebrospinal fluid white blood cell count and cerebrospinal fluid protein levels.

INTRODUCTION: Brain herniation is a known complication of acute bacterial meningitis. Brain CT is requested before the lumbar puncture to rule out increased intracranial pressure. Delay antibiotic administration, secondary to brain CT leads to a poor clinical outcome.CASE PROFILE: 10 year old boy had previous history of skull fracture and pneumococcal meningitis, presented to ER with history of fever, headache and vomiting for 2 days. Clinically, he was fully conscious and vitally stables with positive meningeal signs and normal other examinations. Brain CT was normal before the lumbar puncture. The lumbar puncture came suggestive of meningitis in the form of leukocytosis with low glucose and high protein. Antibiotics were given after the lumbar puncture. Two hours after the lumbar puncture, the patient had deteriorations in the level of consciousness and respiratory arrest followed by a coma. Brain CT was repeated which showed cerebellar herniation and subarachnoid hemorrhage. Neuroprotective strategy was performed without improvements. Blood and CSF cultures showed pneumococcal growth. After onne week, brain death was confirmed.CONCLUSION: Brain herniation is a severe complication of bacterial meningitis. Clinical findings are the best indicators to delay the LP and to predict the risk of herniation. Normal brain CT doesn’t necessarily mean LP is safe. Early antibiotics administrations improve the mortality and morbidity. Unnecessary CT before the LP lead to a delay of antibiotic administration and poor outcome.

The Limulus amoebocyte lysate endotoxin assay was evaluated as a method for rapid diagnosis of acute bacterial meningitis in a series of 305 patients. The results of Limulus assays on cerebrospinal fluid (CSF) samples from these patients were compared with the results for each patient of routine bacterial cultures and Gram stains. Positive Limulus tests were obtained on initial CSF specimens from 84% of patients with culture-proven bacterial meningitis, including all patients with meningitis due to gram-negative organisms. Initial Gram-stained smears revealed the presence of organisms in 68% of the patients. One patient with pneumococcal meningitis had a weakly positive Limulus assay, whereas patients with meningitis due to other gram-positive organisms, those with aseptic meningitis, or patients without meningitis had negative CSF Limulus tests. The Limulus assay also demonstrated the persistence of endotoxin in the CSF of certain patients during antibiotic therapy, especially patients with Haemophilus influenzae meningitis. The Limulus test proved to be a rapid, reliable indicator of the presence of gram-negative organisms in the CSF of patients suspected of acute bacterial meningitis.

Objective. Despite the lack of evidence defining a time interval during which cerebrospinal fluid (CSF) culture yield will not be affected by previous antibiotic therapy, recent publications cite a “minimum window” of 2 to 3 hours for recovery of bacterial pathogens after parenteral antibiotic administration. We conducted a retrospective review of children with bacterial meningitis to describe the rate at which parenteral antibiotic pretreatment sterilizes CSF cultures. Methods. The medical records of pediatric patients who were discharged from a tertiary children's hospital during a 5-year period with the final diagnosis of bacterial meningitis or suspected bacterial meningitis were reviewed. The decay in yield of CSF cultures over time was evaluated in patients with lumbar punctures (LP) delayed until after initiation of parenteral antibiotics and in patients with serial LPs before and after initiation of parenteral antibiotics. Results. The pathogens that infected the 128 study patients were Streptococcus pneumoniae (49),Neisseria meningitidis (37), group BStreptococcus (21), Haemophilus influenzae (8), other organisms (11), and undetermined (3). Thirty-nine patients (30%) had first LPs after initiation of parenteral antibiotics, and 55 (43%) had serial LPs before and after initiation of parenteral antibiotics. After ≥50 mg/kg of a third-generation cephalosporin, 3 of 9 LPs in meningococcal meningitis were sterile within 1 hour, occurring as early as 15 minutes, and all were sterile by 2 hours. With pneumococcal disease, the first negative CSF culture occurred at 4.3 hours, with 5 of 7 cultures negative from 4 to 10 hours after initiation of parenteral antibiotics. Reduced susceptibility to β-lactam antibiotics occurred in 11 of 46 pneumococcal isolates. Group B streptococcal cultures were positive through the first 8 hours after parenteral antibiotics. Blood cultures were positive in 74% of cases without pretreatment and in 57% to 68% of cases with negative CSF cultures. Conclusions. The temptation to initiate antimicrobial therapy may override the principle of obtaining adequate pretreatment culture material. The present study demonstrates that CSF sterilization may occur more rapidly after initiation of parenteral antibiotics than previously suggested, with complete sterilization of meningococcus within 2 hours and the beginning of sterilization of pneumococcus by 4 hours into therapy. Lack of adequate culture material may result in inability to tailor therapy to antimicrobial susceptibility or in unnecessarily prolonged treatment if the clinical presentation and laboratory data cannot exclude the possibility of bacterial meningitis.

ABSTRACT In vitro levofloxacin exhibits both potent or intermediate activity against most of the pathogens frequently responsible for acute bacterial meningitis and synergistic activity with some beta-lactams. Since levofloxacin was shown to penetrate the cerebrospinal fluid (CSF) during meningeal inflammation both in animals and in humans, the disposition of levofloxacin in CSF was studied in 10 inpatients with external ventriculostomy because of communicating hydrocephalus related to subarachnoid occlusion due to cerebral accidents who were treated with 500 mg of levofloxacin intravenously twice a day because of extracerebral infections. Plasma and CSF concentration-time profiles and pharmacokinetics were assessed at steady state. Plasma and CSF levofloxacin concentrations were analyzed by high-pressure liquid chromatography. The peak concentration of levofloxacin at steady state (C max ss)was 10.45 mg/liter in plasma and 4.06 mg/liter in CSF, respectively, with the ratio of the C max ss in CSF to the C max ss in plasma being 0.47. The areas under the concentration-time curves during the 12-h dosing interval (AUC0-τs) were 47.69 mg · h/liter for plasma and 33.42 mg · h/liter for CSF, with the ratio of the AUC0-τ for CSF to the AUC0-τ for plasma being 0.71. The terminal-phase half-life of levofloxacin in CSF was longer than that in plasma (7.02 ± 1.57 and 5.51 ± 1.36 h, respectively; P = 0.034). The ratio of the levofloxacin concentration in CSF to the concentration in plasma progressively increased with time, from 0.30 immediately after dosing to 0.99 at the end of the dosing interval. In the ventricular CSF of patients with uninflamed meninges, levofloxacin was shown to provide optimal exposure, which approximately corresponded to the level of exposure of the unbound drug in plasma. The findings provide support for trials of levofloxacin with twice-daily dosing in combination with a reference beta-lactam for the treatment of bacterial meningitis in adults. This cotreatment could be useful both for overcoming Streptococcus pneumoniae resistance and for enabling optimal exposure of the CSF to at least one antibacterial agent for the overall treatment period.

Rule Out

Elevation of cerebrospinal fluid (CSF) cell count is a key sign in the diagnosis of bacterial meningitis. However, there have been reports of bacterial meningitis with no abnormalities in initial CSF testing. This type of presentation is extremely rare in adult patients. Here, a case involving an 83-year-old woman who was later diagnosed with bacterial meningitis caused byNeisseria meningitidisis described, in whom CSF at initial and second lumbar puncture did not show elevation of cell counts. Twenty-six non-neutropenic adult cases of bacterial meningitis in the absence of CSF pleocytosis were reviewed. The frequent causative organisms wereStreptococcus pneumoniaeandN meningitidis. Nineteen cases had bacteremia and seven died. The authors conclude that normal CSF at lumbar puncture at an early stage cannot rule out bacterial meningitis. Therefore, repeat CSF analysis should be considered, and antimicrobial therapy must be started immediately if there are any signs of sepsis or meningitis.

Meningitis In Children

The sequelae of acute bacterial meningitis in children who were treated with ampicillin or chloramphenicol for seven days during the period January 1979 to June 1983 were assessed prospectively. The 235 patients (117 boys and 118 girls) ranged in age from four days to 18 years (mean 26.4 months). Haemophilus influenzae type b was isolated in 70% of patients, Streptococcus pneumoniae in 20%, and Neisseria meningitidis in 10%. The mortality rate was 6.4%. No relapses occurred. Of the 220 survivors, 171 had neurologic psychometric, audiologic, and ophthalmologic assessments performed for a minimum of 1 year following their illness. One hundred thirty-six (80%) children had no detectable sequelae; 20% had mild to severe handicaps. The frequency of sequelae was greatest among children with S pneumoniae meningitis (57%) and least among children with N meningitidis (0%). The sequelae observed included: sensorineural hearing loss (12.9%), developmental delay (5.3%), speech defect (4.7%), motor defect (3.0%), hydrocephalus (1.7%), and seizure disorder (1%). The frequency of observed sequelae among these patients is similar to that previously reported in children treated for ten to 14 days. Our findings indicate that seven days of intravenous antibiotic therapy is adequate for the treatment of bacterial meningitis in children.

Acute bacterial meningitis is a life-threatening infection. By definition, meningitis is an infection of the meninges and the subarachnoid space. Bacterial meningitis is associated with an inflammatory response that involves the meninges, the subarachnoid space, the brain parenchyma, and the cerebral arteries and veins. As such, bacterial meningoencephalitis is the more accurate descriptive term. This chapter discusses the epidemiology, etiology, pathophysiology and pathogenesis, diagnosis, differential diagnosis, treatment, complications, and prognosis of the disease. The discussion of diagnosis covers clinical manifestations, physical examination findings, laboratory tests, and imaging studies. The discussion of treatment covers empirical therapy, specific antimicrobial therapy, and dexamethasone therapy. Graphs compare causative organisms and clinical manifestations of community-acquired meningitis. Illustrations depict proper patient positioning for detecting nuchal rigidity, Kernig sign, Brudzinski sign, and lumbar puncture, as well as a sagittal view of a lumbar puncture needle as it is advanced into the subarachnoid space. An algorithm delineates the approach to the patient with symptoms and signs of bacterial meningitis. Tables outline bacterial pathogens based on predisposing and associated conditions, cerebrospinal fluid diagnostic studies for meningitis, the appearance of the organism on a Gram stain, empirical antimicrobial therapy based on predisposing and associated conditions, recommendations for specific antibiotic therapy in bacterial meningitis, and recommended doses for antibiotics commonly used in the treatment of bacterial meningitis.   This review contains 8 highly rendered figures, 6 tables, and 75 references.
