    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.

    ABSTRACT: Corticosteroid and the combination of corticosteroid and antihelminthic drug are safe and beneficial in relieving headaches in patients with eosinophilic meningitis. However, clinical trials comparing the efficacies of these regimens have never been reported. We conducted a prospective, open, randomized, controlled study to compare the efficacy of the combination of prednisolone plus albendazole and prednisolone alone for the treatment of eosinophilic meningitis. Our study had 53 patients in the combined treatment group and 51 patients in the prednisolone alone group. There were no significant differences between the two groups with regard to the number of patients who still had headaches after 14 days (0 versus 1, respectively; P = 0.49) and the median length of time until complete disappearance of headache (3 versus 3 days, respectively; P = 0.32. Prednisolone plus albendazole is no better than prednisolone alone for treatment of patients with eosinophilic meningitis.

    ABSTRACT: The levels of interleukin 5 (IL5), IL10, and IL13 in the cerebrospinal fluid (CSF) were markedly higher in 30 patients with eosinophilic meningitis associated with angiostrongyliasis (EOMA) than in the controls (P<0.001). IL2, IL4, interferon gamma (IFNgamma), and tumor necrosis factor alpha (TNFalpha) levels were not significantly different (P>0.05). IL5, IL10, and TNFalpha levels correlated with eosinophil levels (P=0.023, P=0.018, and P=0.005, respectively) while IL2, IL4, IL13, and IFNgamma did not (P>0.05). Our data suggest that local T-helper-2 (TH2) cytokine responses are predominant in the CSF of patients with EOMA. Data on T lymphocyte-parasite interactions are important for the design of effective vaccines and immunotherapies. The measurement of T-helper-1 (TH1)/TH2 cytokines in the CSF may also have some potential for the diagnosis of parasite associated meningitis.

    ABSTRACT: Eosinophilic meningitis associated angiostrongyliasis (EOMA) is a harmful disease of the brain and spinal cord caused by a parasitic helminth, Angiostrongylus cantonensis, presenting with severe headaches and cerebrospinal fluid (CSF) eosinophilia. However, the immunologic pathophysiology especially in relation to the eosinophilic inflammation is still unknown. We measured the CSF concentrations of eotaxin and eotaxin-2 of 30 patients and 10 controls. The CSF eotaxin and eotaxin-2 levels of the EOMA patients were significantly higher than those of the controls (p<0.001). The positive detection values were 83.3% (25/30) and 93.3% (28/30) for eotaxin and eotaxin-2, respectively. CSF eotaxin-2 levels also correlated with CSF eosinophilia (p=0.002). These results might indicate that the recruitment of eosinophils to the brain and spinal cord in EOMA patients could be related to elevated eotaxin-2 levels.
