Aminoterminal pro-C type natriuretic peptide (NT-proCNP) as an active form of CNP, has been recently proven to be a potential marker of sepsis and to be linked to inflammatory diseases. So far, there are no studies describing the level of NT-proCNP in meningitis. The purpose of this study was to evaluate the diagnostic value of NT-proCNP in cerebrospinal fluid (CSF) in patients with meningitis and to compare it with the serum level of CRP and procalcitonin (PCT) in this group of patients. The results were compared to serum levels of CRP, PCT and CSF levels of cytosis, protein and lactate. NT-proCNP levels were statistically significant between the control group and the meningitis groups (p = 0.02; R = 0.3). We also noted a correlation between the level of NT-proCNP in the CSF of all of the study groups (controls and meningitis patients) and the CSF levels of cytosis (p < 0.5; R = 0.43), protein (p < 0.05; R = 0.39) and lactate (p < 0.05; R = 0.34), and also the serum level of CRP (p < 0.05; R = 0.30), but not serum PCT (p > 0.05; R = 0.11). These results suggest that NT-proCNP could be a potential marker of meningitis, but it cannot be used to distinguish between the types of meningitis.
