Abstract
The level of autoantibodies (aAB) to main structural component of glutamate NMDA-receptors--phencyclidin-binding protein--was measured in blood serum of 70 patients during first 3, 6, 9, 12, 24 hours, and 3, 5 days after ischemic stroke development. 200 healthy individuals formed the control group. The elevation of titers of aAB to glutamate receptors was observed in all patients with severe or moderate disease from the very first hours of stroke. It was especially pronounced by 9-12 hours after stroke. The highest increase of aAB titers was found in severe cases. The tendency to normalization of aAB titers was observed by the end of the first twenty four hours. The degree of aAB elevation had the prognostic importance. The most favourable course of stroke with good restoration of damaged functions was predicted when stable normalization of the aAB level was observed by the third day of the disease development. Patients in stupor-coma condition did not show the phenomenon of aAB level's elevation during the first days of stroke, that reflected, probably, the development of immuno-deficient state. The decrease of aAB level down to subnormal values was extremely unfavourable prognostic sign proceeding patient's death as a rule.
