INTRODUCTION: There is a growing interest to know the characteristics of meningoencephalitis due to Angiostrongylus cantonensis because of it is an emergent disease. OBJECTIVE: To describe the intrathecal synthesis pattern of IgG subclasses in pediatric patients suffering from eosinophilic meningoencephalitis due to Angiostrongylus cantonensis. PATIENTS AND METHODS: Ten pediatric patients with the disease were studied. During the firs diagnostic lumbar puncture an eosinophilic pleocitosis was found. Simultaneously a serum sample was taken. Eight days later, a second lumbar and venous puncture was performed. To every serum and cerebrospinal fluid sample IgA, IgM, IgG, albumin and the four subclasses of IgG were quantified by immunodiffusion and a differential cell count. RESULTS: During the first diagnostic lumbar puncture, all the cases had blood cerebrospinal fluid barrier dysfunction with absence of immunoglobulins intrathecal synthesis with a mean of 450 106cells/L and 48% of eosinophils average. In the second lumbar punction there was a 40% patients with dysfunction of the blood cerebrospinal fluid barrier and with a synthesis pattern IgA+IgM+IgG in the 50% o patients and with IgA+IgG in four patients. The synthesis pattern of IgG subclasses was IgG1+IgG2 in six patients, IgG1+IgG2+IgG3 in one patient, IgG1+IgG2+IgG4 in one more patient and two patients without intrathecal synthesis. CONCLUSION: The intrathecal synthesis pattern of IgG subclasses can contribute to eosinophilic meningoencephalitis diagnosis due to Angiostrongylus cantonensis.
