Background: Interleukin 8 increases in various types of meningitis, specifically acute bacterial meningitis inflammation, and it is important in the distinction between types of meningitis. The present paper aims at evaluation of the level of interleukin 8 in cerebrospinal fluid in acute adult bacterial meningitis. Methods: All adult patients’ with diagnosis of suspected meningitis with symptoms of fever, headache, neck stiffness, and consciousness disorder. Lumbar puncture was taken in between the third and fourth vertebra by a specialist physician for all patients suspected with meningitis. To determine the level of consciousness, the GCS of the patients was determined and the cerebrospinal fluid was cultured and sent to the laboratory for the analyses of cell count, diffraction, CSF fluid glucose, CSF fluid protein, LDH, or lactate dehydrogenase, and the level of interleukin 8. Results: The mean of IL-8 protein was 296.17±48.57Pg/ml in patients with aseptic meningitis and 1088.96±526.55Pg/ml in the group of patients with septic meningitis. There was a significant difference between the two groups in terms of the amount of interleukin 8 (p = 0.009). Cutoff was 297.6 Pg/ml for the detection of positive bacterial meningitis with a sensitivity of 92% and the specificity of 83.1% was 297.6 pg/ml. Conclusion: Interleukin 8 has a high sensitivity and specificity in the diagnosis of bacterial meningitis from aseptic meningitis, and along with the measurement of cerebrospinal fluid protein, it can be a good criterion for differentiation of bacterial from aseptic 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.

Abstract Cerebrospinal fluid (CSF) neopterin been previously reported in various diseases. In this study CSF neopterin, biopterin, and nitrite/nitrate (NOx) Contents were measured and the correlation between them in child patients with various kinds of neurological diseases were investigated. Changes in the CSF neopterin levels in patients with bacterial meningitis were similar to those previously reported for those with bacterial meningitis; on the 2th hospital day they were significantly higher than on admission, and on the 6th hospital day they were tapered. The CSF biopterin levels and CSF NOx content in patients with bacterial meningitis on admission were significantly higher than those with other categories and were decreased gradually. Although patients with high levels of CSF neopterin tended to have high CSF biopterin levels in any categories, there was no significant correlation between CSF neopterin and biopterin levels. The CSF biopterin and NOx levels in patients with convulsions were higher than those with aseptic meningitis. Since the neuro-protective or anticonvulsant role for NO was previously reported, high CSF biopterin and NOx levels in patients having epilepsy or febrile convulsions may be regarded as one of the endogenous mechanisms for recovery from an overexcitatory brain in patients with convulsive diseases.

Abstract Background The timely diagnosis of bacterial meningitis is of utmost importance due to the need to institute antibiotic treatment as early as possible. Moreover, the differentiation from other causes of meningitis/encephalitis is critical because of differences in management such as the need for antiviral or immunosuppressive treatments. Considering our previously reported association between free membrane phospholipids in cerebrospinal fluid (CSF) and CNS involvement in neuroinfections we evaluated phosphatidylcholine PC ae C44:6, an integral constituent of cell membranes, as diagnostic biomarker for bacterial meningitis. Methods We used tandem mass spectrometry to measure concentrations of PC ae C44:6 in cell-free CSF samples (n = 221) from patients with acute bacterial meningitis, neuroborreliosis, viral meningitis/encephalitis (herpes simplex virus, varicella zoster virus, enteroviruses), autoimmune neuroinflammation (anti-NMDA-receptor autoimmune encephalitis, multiple sclerosis), facial nerve and segmental herpes zoster (shingles), and noninflammatory CNS disorders (Bell’s palsy, Tourette syndrome, normal pressure hydrocephalus). Results PC ae C44:6 concentrations were significantly higher in bacterial meningitis than in all other diagnostic groups, and were higher in patients with a classic bacterial meningitis pathogen (e.g. Streptococcus pneumoniae, Neisseria meningitidis, Staphylococcus aureus) than in those with less virulent or opportunistic pathogens as causative agents (P = 0.026). PC ae C44:6 concentrations were only moderately associated with CSF cell count (Spearman’s ρ = 0.45; P = 0.009), indicating that they do not merely reflect neuroinflammation. In receiver operating characteristic curve analysis, PC ae C44:6 equaled CSF cell count in the ability to distinguish bacterial meningitis from viral meningitis/encephalitis and autoimmune CNS disorders (AUC 0.93 both), but had higher sensitivity (91% vs. 41%) and negative predictive value (98% vs. 89%). A diagnostic algorithm comprising cell count, lactate and PC ae C44:6 had a sensitivity of 97% (specificity 87%) and negative predictive value of 99% (positive predictive value 61%) and correctly diagnosed three of four bacterial meningitis samples that were misclassified by cell count and lactate due to low values not suggestive of bacterial meningitis. Conclusions Increased CSF PC ae C44:6 concentrations in bacterial meningitis likely reflect ongoing CNS cell membrane stress or damage and have potential as additional, sensitive biomarker to diagnose bacterial meningitis in patients with less pronounced neuroinflammation.

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.

Background Meningitis is a serious infection. Little is known about the bacterial agents and their antibacterial sensitivity in Nepalese children. Objectives To study bacteriological agents, clinical profile and immediate outcome in patients admitted to children’s ward of Patan Hospital with meningitis. Methods Prospective observational study conducted in paediatric ward of Patan Hospital. All the children admitted to the ward, with the diagnosis of culture proven bacterial meningitis’ on discharge were eligible. Results Out of 7,751 children, 296 (3.8%) had meningitis. This was a group ranging from neonates to adolescents aged 18 years. Only 13 (4.4%) of cerebrospinal fluid samples taken from them yielded positive culture reports. The organisms were pneumococcus (6), Haemophilus influenza ‘b’ (3), ?-hemolytic Streptococcus (1), ?-hemolytic Streptococcus (1), N. meningitides (1) and Pseudomonas (1). Whereas Haemophilus influenza ‘b’ was isolated from young infants, pneumococci were found in the young as well as the old. Fever, vomiting, high leukocyte count with left shift were all commonly present. All but one had cerebrospinal fluid pleocytosis. Low sugar and high protein was found in most specimens. Neuroimaging was done in six children of which three were abnormal (all young infants and pneumococci cases). Ceftriaxone was given to all but one child. Everybody recovered but three had complications – profound hearing loss and cortical atrophy with subdural collection in pneumococcal and septic arthritis with persistence of fever in Haemophilus influenzae ‘b’ meningitis. Conclusion The present study corroborates most of the epidemiological and clinical features of acute bacterial meningitis and sheds light on the causative agents of bacterial meningitis in Nepalese children. http://dx.doi.org/10.3126/kumj.v9i1.6260 Kathmandu Univ Med J 2011;9(1):36-40
