Are [ Immunological disorders in epileptic patients associated to the epileptogenic focus localization ]? Context: Clinical and experimental data support the role of immune mechanisms in the pathogeny of epilepsy. The purpose of this work was to study the immunological aspects in 30 epileptic patients with complex partial crisis resistant to antiepileptic drugs. The patients were evaluated by EEG-Video and they were grouped attending to epileptogenic focus localization in: temporals (n = 16), lateralized (n = 6) and extratemporals (n = 4). We also studied a group with psychogenic epilepsy (n = 4), this group was diagnosed after EEG-video evaluation. The following immunological evaluations has been carried out: levels of serum immunoglobulins (IgG, IgM e IgA) by radial immunodiffusion test and lymphocytic subpopulations using immunocytochemical methods. We measured the percent of T and B lymphocytes (CD3 and CD20), helper/inductor lymphocyte T (CD4), suppressor/cytotoxic (CD8), interleukine-2 receptor (CD25) and human leukocyte antigen (HLA-DR). The results show a significant increase of CD8+ lymphocytes (p < 0.05) and in the activation markers (CD25+ and HLA-DR+ cells). The evaluation of immunological parameters applied to different group of epileptogenic focus localization shown that the increase of CD8+ lymphocytes is limited to temporal and lateralized patients (p < 0.01). The patients with extratemporal localization of focus and the psychogenic cases shown normal values for the evaluated immunological lymphocyte markers. We did not find a deficit in the humoral immunological aspects.

Taking into account that patients diagnosed as psychogenic received an antiepileptic drug treatment identical to that of the other group, the observed immunological changes might be related with the patogeny of certain epilepsy variants associated with the focus localization and not with the medication. Final Decision: yes
