OBJECTIVES: The aim of this paper is to analyze and assess the usefulness of heat shock protein 70 (Hsp70) and circulating immune complexes (CIC) in patients with sudden sensorineural hearing loss (SSHL) in a tertiary care hospital in a research university (2014-2017).


MATERIALS and METHODS: Patients were interviewed about the history of diseases; underwent an ear, nose, and throat (ENT) examination; a hearing test; and were analyzed for the presence of CIC and Hsp70 protein. A simple dot blot method was designed for the purpose of identification of Hsp70 bound to CIC and free Hsp70.


RESULTS: In 59.4% of patients with idiopathic SSHL, elevated levels of immune complexes were observed. Compared with healthy subjects, a significant difference was noted (p=0.00016). Positive reactions to the presence of free Hsp70 protein were noted in the sera of 48.4% of patients. In the control group, free Hsp70 was observed in 8% of patients (p=0.0000034). Hsp70 bound to CIC was detected in the sera of 62.5% of patients; and in healthy cases, in 12% (p<0.0001).


CONCLUSION: In the sera of persons with SSHL, there are elevated levels of CIC and Hsp70. After the application of the innovative method for determining the occurrence of Hsp70 bound to CIC, it was stated that its presence is greater than that of free Hsp70, commonly detected by means of the Western-blot method. The dot blot method applied in the present study increases the Hsp70 identification and by the same token increases the probability of detection of autoimmunological background of SSHL.
