[Antibodies to neuromediators in allergic diseases (pollinosis)]

Sera from 33 pollinosis patients aged 16-33 have been examined for autoantibodies to neuromediators serotonin and catecholamine, serum samples from 21 healthy subjects served controls. Antibodies to dopamine and norepinephrine (43.0 +/- 4.0, 35.0 +/- 0.0 rel. units) have been detected in 81.8% and 69.7% of the pollinosis patients, respectively. Serotonin antibodies (54.6 +/- 6.0 rel. units) occurred in the patients 3.8 times more frequently than in healthy subjects. Antibodies to neuromediators in quantities within 12.0 rel. units were recorded in 9.5-38.0% of the controls. It is suggested that induction of neuromediator antibodies synthesis may represent a compensatory mechanism of neuromediator metabolism control in pollinosis.
