ABSTRACT
Meningitis caused by Angiostrongylus cantonensis has recently been reported in patients resulting from the first outbreaks in subtropical regions of Ecuador.

METHOD:

Eight young adult patients from the two outbreaks were studied. IgA, IgM, IgG and albumin in cerebrospinal fluid and serum were quantified and plotted in cerebrospinal fluid/serum quotient diagrams (Reibergrams). The anamnesis on the patients included asking about any consumption of raw snails, symptoms and harm caused.

RESULTS:

Mean eosinophilia of 7.5 percent and 26 percent in serum and cerebrospinal fluid respectively was observed, as well as a moderate increase in total proteins. The most frequent pattern of intrathecal synthesis was observed in three classes of immunoglobulins. Intrathecal synthesis of IgM was observed in all cases two weeks after the first symptoms appeared.

CONCLUSION:

The intrathecal synthesis patterns of eosinophilic meningitis due to Angiostrongylus cantonensis, facilitated by cerebrospinal fluid analysis, were similar to those of previous cases from abroad.
RESUMEN
La meningitis provocada por Angiostrongylus cantonensis ha sido reportada recientemente en pacientes procedentes de los primeros brotes reportados en regiones subtropicales de Ecuador.

MÉTODO:

Ocho adultos jóvenes procedentes de dos brotes fueron estudiados. Se cuantificó IgA, IgM, IgG y albúmina en suero y líquido cefalorraquídeo y fueron colocados en los gráficos de las razones líquido cefalorraquídeo/suero (reibergramas). La anamnesia incluía ingestión de caracoles crudos, los síntomas y los daños provocados.

RESULTADOS:

Una eosinofílica promedio de 7,5 y 26 por ciento en suero y líquido cefalorraquídeo fue observada al igual que un moderado incremento en las proteínas totales. El patrón de síntesis intratecal predominante fue de tres clases de inmunoglobulinas. La síntesis intratecal de IgM se observó en todos los casos a las dos semanas después del inicio de los síntomas.

CONCLUSIÓN:

El patrón de síntesis intratecal de la meningitis eosinofílica por Angiostrongylus cantonensis facilitado por el análisis del líquido cefalorraquídeo fue similar a los casos previos reportados fuera del país.
