N2 - We studied 82 patients with different types of epilepsy and 49 neurologically intact non-epileptic controls, and identified three different subpopulations of epilepsy patients bearing significantly elevated levels of autoantibodies to either GluR3B-peptide of glutamate/AMPA receptor subtype 3 (17/82; 21% of patients), or to a peptide of NR2A subunit of glutamate/NMDA receptors (15/82; 18%), or to double-stranded (ds) DNA, the hallmark of systemic lupus erythematosus (13/80; 16%). Most patients had only one antibody type, arguing against cross-reactivity. Nearly all anti-dsDNA Ab-positive patients did not harbor anti-nuclear autoantibodies. Most patients had no history of brain damage, febrile convulsions, early onset epilepsy, acute epilepsy or intractable seizures. We suggest to measure the 'autoimmune-fingerprints' of epilepsy patients for diagnostic and therapeutic purposes.
