The etiology of sensorineural hearing loss (SNHL) in children may be viral. This cross-sectional study aimed to determine the role of viral infectious agents in children with idiopathic SNHL. Of 119 children with SNHL aged 3-168 months undergoing cochlear implant surgery at a hospital in Tehran, no cause could be established in 18 cases (15.1%). Cytomegalovirus (CMV) and herpes simplex virus (HSV) active infections (detected by DNA-PCR, confirmed by serology) were found in the perilymphatic fluid of 16.7% (3/18) cases of idiopathic SNHL. Serology was performed on blood samples from 11 of these cases: specific antibodies against CMV, Toxoplasma spp., HSV and rubella were determined in all cases; acute T. gondii infection was detected in 7 cases and rubella IgG was found in only 1 case. Neonatal screening for CMV, HSV and T gondii may be helpful in the Islamic Republi of Iran.
儿童感音神经性听力损失(SNHL)的病因可能是病毒。本横断面研究旨在确定病毒感染因子在特发性 SNHL 儿童中的作用。在德黑兰一家医院接受耳蜗植入手术的 119 名 3-168 月龄的 SNHL 儿童中,18 例(15.1%)无法确定病因。在 18 例特发性 SNHL 中,有 16.7%(3/18)的病例发现了细胞巨化病毒(CMV)和单纯疱疹病毒(HSV)的活动性感染(通过 DNA-PCR 检测,通过血清学证实)。对其中 11 例进行了血清学检查:对所有病例均检测了针对 CMV、弓形体病、HSV 和风疹的特异性抗体;在 7 例中检测到急性弓形体病感染,仅在 1 例中发现风疹 IgG。在伊朗伊斯兰共和国,对 CMV、HSV 和 T 弓形体病进行新生儿筛查可能会有所帮助。
