Abstract
Cerebrospinal fluid (CSF) urokinase-type plasminogen activator (uPA) and matrix metalloproteinase-9 (MMP-9) levels were measured in patients with eosinophilic meningitis associated with angiostrongyliasis (EOMA) by quantitative sandwich enzyme immunoassays. The CSF concentrations of uPA and MMP-9 were evaluated in 30 EOMA patients and 10 controls. The CSF uPA and MMP-9 levels of the EOMA patients were significantly higher than those of the controls (p<0.001). The positive detection values were 73% (22/30) and 86.7% (26/30) for uPA and MMP-9, respectively. The uPA detection was in correlation with headache duration (p=0.008) and stiff neck (p=0.048), while the MMP-9 was in correlation with CSF total protein (p=0.006), CSF leukocytosis (p=0.004) and CSF eosinophil numbers (p=0.02). CSF uPA and MMP-9 levels are potentially useful for the understanding of immunologic pathogenesis, for therapeutic targets, for the diagnosis of EOMA and for monitoring treatment efficacy.
