Background: Meningitis is one of the serious and dangerous infections in the infancy and childhood and rapid diagnosis of meningococcal disease is important, especially in infants. C-reactive protein (CRP) is a protein found in blood and is an acute phase protein. CRP sensitive reactive that used for diagnosis of infection. This study conducted to assessment of the relationship between cerebrospinal fluid C-reactive protein, and neonatal meningitis, as well as diagnostic value of test.
Methods: Forty nine hospitalized infant that suspected to meningitis were enrolled in this analytic cross sectional research via non probable accessible sampling. 28 patients (52.7%) of all the patients were male and 21 patients (42.8%) were female. The average age of the patients was 22.6±11.88 days. Data from clinical examinations and laboratory tests entered in a questionnaire and all of samples divided in two bacterial (septic) and non-bactria (aseptic) meningitis group. All data including cerebrospinal fluid CRP of newborns were statistically analyzed.
Results: In total, the mean and standard deviation of age was 22.6±11.88 days. 57.2% of infants were male and 42.8% were female. In total, 40.82% of infants were diagnosed with septic meningitis. There was no significant difference between septic and aseptic groups in terms of sex (P= 1.00) also in terms of age (P= 0.1). The mean and standard deviation of CRP level in septic meningitis group was 0.95±0.68 mg/L and in aseptic group was 0.16±0.36 mg/L. The CRP level difference in septic meningitis group compare with aseptic group was statistically significant (P<0.000). The finding showed that cut off point for CRP level as a diagnostic test was 0.17 mg/L, sensitivity was 95% and specificity was 86%.
Conclusion: In the present study, newborns with septic meningitis had higher cerebrospinal fluid CRP level than newborns with aseptic meningitis, and CSF-CRP can be used in rapid diagnosis of septic and aseptic meningitis. Although this result has been seen in many studies, but more research is needed.
