Abstract

Background: Many studies have found that viral infections affect different tissues, including the inner ear. Coronavirus disease 2019 (COVID-19), a viral infection, is a significant health problem worldwide. Prestin is a motor protein with important functions both in the outer hair cells of the inner ear and in cardiac tissue. In addition, prestin is promising as an early biomarker in the detection of ototoxicity. To determine the severity of infection in COVID-19 patients and to determine whether other tissues are affected by the infection, lactate dehydrogenase (LDH), C-reactive protein (CRP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase MB (CK-MB), biochemical markers such as ferritin and D-dimer are used. This study aimed to compare prestin levels in patients with COVID-19 and healthy volunteers.

Methods: In blood samples taken from 45 patients diagnosed with COVID-19 and 40 healthy volunteers, prestin levels were determined with the kit that used an enzyme-linked immunosorbent assay method and was commercially available. At the same time, LDH, CRP, ALT, AST, CK-MB, ferritin, and D-dimer levels were also detected in both patients and healthy control groups and correlations with prestin levels were examined.

Results: The main result of our study is that serum prestin levels in COVID-19 patients are significantly higher than in healthy controls ( p < 0.001). In addition, a statistically significant strong positive correlation was found between prestin-LDL ( r = 0.537, p = 0.001), prestin-CRP ( r = 0.654, p = 0.001), and prestin-D-dimer ( r = 0.659, p = 0.001).

Conclusion: The levels of prestin, a motor protein in inner ear outer hair cells and cardiac myocytes, were found to be higher in COVID-19 patients than in healthy volunteers. It also showed a positive correlation with CRP and D-dimer. This may be associated with systemic dysfunction.
