[IgG subclasses intrathecal synthesis patterns in eosinophilic meningoencephalitis due to Angiostrongylus cantonensis].
Rev Neurol. 2003 Mar 16-31; 36(6):506-9.RN

Abstract

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.
