Abstrakt: Research background and aim: There is not any routine serum biomarker for diagnosing hearing loss (HL). An inner ear-specific protein, prestin can be measured as a serum biochemical marker for HL diagnosis. The present study investigates, for the first time, the relationship between prestin serum levels and sensorineural HL (SNHL) in an Iranian population. Materials and methods: In this case–control study, 176 samples were examined in four groups including two control and two SNHL groups of 20–50 and ≥ 50 years with different severities of SNHL. Plasma prestin concentration was measured using Human Prestin (SLC26A5) ELISA Kit. Data analysis was conducted using SPSS v.23 with level of significance as 0.05. Results: Groups with SNHL had higher prestin levels (Mean = 182.29, SD = 71.24) compared to the control groups (Mean = 122.50, SD = 57.1) (P < 0.001). Results of the multinomial logistic regression of relationship between prestin level and SNHL remained significant after controlling intervening variables (P < 0.001 and odds ratio = 1.017 and 95% CI OR: 1.01–1.024). Results of the ordinal logistic regression model revealed that prestin level was significantly associated with the degree of HL (P < 0.001 and Odds ratio = 1.009 and 95% CI and OR: 1.005–1.013), so that the likelihood of HL increased with the rise in prestin levels. The best cutoff point for the 20–50 group was the prestin content of 132.5 pg/ml (sensitivity: 75%, specificity: 70.05%), while for the group of ≥ 50 was as 130 pg/ml (sensitivity: 84.1%, specificity: 68.2%). Conclusions: Results of the present study revealed that prestin acts as a valuable biomarker for SNHL. [ABSTRACT FROM AUTHOR]
