Introduction: Congenital deafness is a hearing loss that occurs at birth. Congenital deafness in neonates can be caused by risk factors during pregnancy and during the birth process. The tests carried out for hearing screening for neonates in hospital up to 1 month old are Otoaccoustic Emission (OAE) and Auditory Brainstem Response (ABR) examinations. Objective: Determining the relationship between family history of deafness, syndromes associated with sensorineural hearing loss, TORCH infection and prenatal syphilis, use of ototoxic drugs during pregnancy, prematurity, low birth weight, asphyxia, and hyperbilirubinemia with the incidence of congenital deafness in children Methods: This cross-sectional study was conducted based on medical record datas from children who underwent OAE and ABR examinations at Dr. Mohammad Hoesin Palembang hospital from January 2019 to February 2021. Results: From the 349 children, 180 (51.6%) had bilateral OAE and ABR pass results, 161 (46.1%) had bilateral referrals and 8 (2.3%) children received unilateral refer results. From 122 children with risk factors, 38 (31.1%) children with bilateral passes, 81 (66.4%) children with bilateral referrals and 3 (2.5 %) children with unilateral refer. From 227 children without risk factors, 142 (62.6 %) children with a bilateral pass, 80 (35.2 %) children with bilateral referrals and 5 (2.2%) children with unilateral refer. The most common risk factor was LBW of 41 (11.7%) children. Chi square test and logistic regression analysis results showed a significant relationship between ototoxic drugs during pregnancy and congenital deafness (p = 0.001) with referral results, the value of Odd Ratio (OR) 9.651. Conclusions: There is a significant relationship between risk factors for ototoxic drugs during pregnancy, TORCH and syphilis infection during pregnancy, asphyxia, congenital syndrome, LBWand hyperbilirubinemia with congenital deafness.

Ototoxic Drug

Sensorineural hearing loss due to ototoxic drugs remains as a conflict as the treatment option with aminoglycosides. Ototoxic mouse model was produced with the administration of ototoxic drugs aminoglycoside kanamycin and loop-diuretic furosemide, thus validation of auditory function of the mouse model is needed to determine the efficacy of the drugs. Kanamycin sulfate 550 mg/kg (VWR life sciences, PA, USA) and furosemide 130 mg/kg (Lasix, Handok, Korea) were administered through subcutaneous and intraperitoneal injection respectively. Auditory brainstem response and distortion otoacoustic emission tests were performed on days 3,5,7,10,14 post administration of the ototoxic drug. Thresholds in response to the stimulus given in the auditory brainstem recordings and distortion otoacoustic emission tests were obtained. The hearing threshold shift to high stimulus intensity was observed post administration of the ototoxic drug. Latency of the ABR peak waves were recorded and analyzed, latency delay was observed as hearing threshold increases. These findings will further support in the application of this animal model in various studies regarding ototoxic hearing loss.

Abstract Background Aging, noise, infection, and ototoxic drugs are the major causes of human acquired sensorineural hearing loss, but treatment options are limited. CRISPR/Cas9 technology has tremendous potential to become a new therapeutic modality for acquired non-inherited sensorineural hearing loss. Here, we develop CRISPR/Cas9 strategies to prevent aminoglycoside-induced deafness, a common type of acquired non-inherited sensorineural hearing loss, via disrupting the Htra2 gene in the inner ear which is involved in apoptosis but has not been investigated in cochlear hair cell protection. Results The results indicate that adeno-associated virus (AAV)-mediated delivery of CRISPR/SpCas9 system ameliorates neomycin-induced apoptosis, promotes hair cell survival, and significantly improves hearing function in neomycin-treated mice. The protective effect of the AAV–CRISPR/Cas9 system in vivo is sustained up to 8 weeks after neomycin exposure. For more efficient delivery of the whole CRISPR/Cas9 system, we also explore the AAV–CRISPR/SaCas9 system to prevent neomycin-induced deafness. The in vivo editing efficiency of the SaCas9 system is 1.73% on average. We observed significant improvement in auditory brainstem response thresholds in the injected ears compared with the non-injected ears. At 4 weeks after neomycin exposure, the protective effect of the AAV–CRISPR/SaCas9 system is still obvious, with the improvement in auditory brainstem response threshold up to 50 dB at 8 kHz. Conclusions These findings demonstrate the safe and effective prevention of aminoglycoside-induced deafness via Htra2 gene editing and support further development of the CRISPR/Cas9 technology in the treatment of non-inherited hearing loss as well as other non-inherited diseases.
