[Preliminary study on erythrocyte immunity during sensorineural hearing loss of unknown etiology]

Red cell immune function was determined in 50 patients with sensorineural deafness and 30 healthy persons as control. The results showed that in patients with sensorineural deafness, the red cell C3b receptor (RBC-C3bR) rosette formation rate (15.10 +/- 1.66) was lowered markedly than controls (18.95 +/- 1.16, P < 0.001) and the red cell surface immune complex (RBC-IC 9.94 +/- 1.68) was elevated markedly than controls (7.44 +/- 1.17, P < 0.001). The results indicate that the red cell immunity in the patients with sensorineural deafness of unknown etiology is lowered.
