Are there relationship otosclerosis with serum HE4 and CA125 level? A pilot study.

BACKGROUND

HE4 and CA 125 are identified as a potential biomarker for the detection of some diseases with fibrosis.

OBJECTIVES

The purpose of this pilot study was to evaluate the value of human epididymis protein 4 (HE4) and cancer antigen-125 (CA-125) in otosclerosis patients.

MATERIAL AND

METHODS

The study population consisted of 60 people (30 otosclerosis patients, 30 control group). We collected blood samples for HE4 and CA-125 levels. Serum HE4 and CA-125 levels were measured by enzyme-linked immunosorbent assay (ELISA). We compared the results between otosclerosis patients and the normal subject. The area under the curve (AUC) of the receiver operating characteristic (ROC) curve was performed to evaluate the diagnostic value.

RESULTS

There was no differences in CA-125 level between the otosclerosis (20.3 U/mL [10.4-42.1] and control group (19.3 U/mL [15.3-49.8]) (p > 0.05). HE4 level was significantly higher in the otosclerosis group (60.9 pmol/L [32.1-101.8])] than the control group (25.3 pmol/L [12.4-91.9]) (p < 0.001). The AUC in ROC analysis of HE4 was 0.768 (p < 0.001).

CONCLUSIONS AND SIGNIFICANCE: Serum HE4 level may be a useful biomarker in otosclerosis. Further studies with a larger number of patients are required to confirm our pilot results.
