Immunoglobulin abnormalities in relatives of IgA deficient epileptics.

Abstract

Serum levels of IgA were found to be reduced in some patients with epilepsy. Further studies revealed that only epileptics with constitutional factors for seizures showed, if ever, IgA deficiency, particularly those treated with hydantoins (up to 25%). In order further to substantiate the association of immunoglobulin alterations with epilepsy nine families in whom the disease was clustered were investigated. An IgA deficiency was detected in 16 of the 19 epileptics (three without hydantoin medication), but in none of their 45 non-epileptic relatives. However, four of the relatives had a low IgM. Seven other families were tested in each of which only one IgA deficient epileptic was known. No other family members were found with a low IgA, but 24 of 58 such relatives had increased IgM serum concentrations. The association of IgA deficiency and epilepsy with IgM imbalances in relatives of IgA deficient epileptics gives additional support for the hypothesis that immune imbalances and certain forms of epilepsy might be linked.
