The association between the levels of autoimmune related indicators and clinical condition in sudden deafness patients

Abstract

This study aimed to analyze the abnormal rates of immune related factors in serum of sudden deafness (SD) patients, and to discuss the correlation between these indicators and the degree of pathological changes of SD patients. From March 2018 to January 2021, 90 patients with SD who were hospitalized in Beijing Tsinghua Changgeng Hospital were enrolled as participants, and 60 healthy examinees served as the control group. Antinuclear antibody (ANA), anticardiolipin antibody immunoglobulin G (ACA-IgG), anticardiolipin antibody immunoglobulin M (ACA-IgM), and anti-β-glucoprotein (anti-β-GP) antibody were detected by enzyme-linked immunosorbent assay (ELISA). In the SD group, 43 participants were positive for ANA, while in the control group, only 9 participants were positive for ANA. The titer of antibodies was significantly higher in the SD group than in the control group. The differences in abnormal rates of ACA-IgG, ACA-IgM, and anti-β-GP antibodies between the SD group and control group were not statistically significant (P>0.05). The pathogenesis of SD is correlated with autoimmune factors to a certain extent. In the course of clinical treatment, in addition to vasodilation, neurotrophic therapy, and thrombolytic therapy, patients can also be approached from the perspective of autoimmunity, which may achieve more ideal treatment effects.
