Autoantibodies to glutamate receptors and products of nitric oxide metabolism in serum in children in the acute phase of craniocerebral trauma.

Levels of serum autoantibodies (aAb) to glutamate receptors and products of nitric oxide (NO) metabolism, i.e., nitrates and nitrites, were assayed in children with recent craniocerebral trauma (CCT) of different levels of severity.

Glutamate receptor autoantibody concentrations in children with chronic post-traumatic headache.

We report here studies on the levels of autoantibodies (aAb) to AMPA glutamate receptors (GluR1 subunit) and NMDA glutamate receptors (NR2A subunit) in serum from 60 children aged 7-16 years with chronic posttraumatic headache (CPTHA) following mild craniocerebral trauma (CCT). The first group consisted of 48 children who had sustained cerebral concussion (CC), of which 34 had single-episode CC (subgroup 1a) and 14 had repeated CC (subgroup 1). The second group included 12 children with mild cerebral contusions (MCC).
