Abstract

Objective: The current study aimed to investigate possible association of maternal SARS-CoV-2 with newborn hearing loss. We compared hearing screening outcomes in neonates born to women with positive SARS-CoV-2 PCR test results during pregnancy with healthy controls.

Methods: Neonates born between April and December 2020 in our hospital to mothers with positive SARS-CoV-2 PCR test results during pregnancy were included in this study. Neonates with risk factors for universal newborn hearing screening (NHS) were excluded. Neonates born to mothers with positive SARS-CoV-2 PCR test results during pregnancy were compared with healthy controls in terms of newborn hearing screening results and independent variables.

Results: Neonates in the COVID-19 group were more likely to have a "refer" result in auditory brainstem responses (ABR) compared with the control group (53/118 and 28/118, respectively; p = 0.001). The second ABR test results did not differ significantly between the groups (p = 0.618). Logistic regression revealed that birth week and type of birth were not associated with the "refer" result. PCR positivity in the second trimester was more likely to produce the "refer" result in the first ABR test (p = 0.014).

Conclusion: SARS-CoV-2 PCR positivity in pregnancy is significantly associated with an increased risk of abnormal NHS results. Also, the timing of PCR positivity in pregnancy (trimester) may be related to abnormal NHS results.
