Objective To investigate the potential role of maternal serum concentrations of placental growth hormone variant (GH‐V), insulin‐like growth factor (IGF) 1 and 2, and IGF‐binding proteins (IGFBP) 1 and 3 in pregnancies complicated by otosclerosis. Method Otosclerosis cases (n = 22) and age, ethnicity‐matched controls (n = 22) were selected in a nested case‐control study. Maternal serum hormone concentrations at 26 and 34 weeks of gestation were determined by enzyme‐linked immunosorbent assay (ELISA). Results Concentrations of all measured hormones except IGFBP‐1 were increased as gestation progressed. Maternal serum GH‐V concentrations at 26 and 34 weeks of gestation were significantly increased in the otosclerosis group, when compared to the control group (2.53 ± 0.17 ng/ml vs. 1.78 ± 0.19 ng/ml, P = 0.036; 4.34 ± 0.31 ng/ml vs. 3.12 ± 0.18 ng/ml, P < 0.001, respectively). Maternal serum IGF‐1 concentrations at 34 weeks in otosclerotic patients were significantly higher than in the controls (589.1 ± 21.4 ng/ml vs. 499.7 ± 17.8 ng/ml, P < 0.001). The increase of IGF‐1 was not observed at 26 weeks of gestation. Serum IGF‐2, IGFBP‐1 and IGFBP‐3 at either 26 or 34 weeks were unaltered between the two groups. Conclusion Maternal serum concentrations of GH‐V and IGF‐1 were altered in pregnancy complicated by otosclerosis, suggesting that the GH‐IGF axis may contribute to the development of this condition during pregnancy.
