Importance of TORCH Profile in Hearing Impaired Paediatric Population Planned for Cochlear Implant: A Study From an Eastern India Tertiary Care Centre.

The Importance of TORCH Profile in Hearing Impaired Children

In the field of pediatric audiology, diagnosing the root cause of hearing loss is crucial for effective intervention. This study focuses on the TORCH group of infections, a common culprit behind bilateral profound hearing loss, especially in developing countries like India. The authors investigated the seroprevalence of TORCH infections in children who were prospective candidates for cochlear implants at AIIMS, Patna, a tertiary care center in eastern India. They employed a retrospective study design, analyzing data from 2017 to 2018 on 50 children diagnosed with bilateral profound hearing loss. The study utilized various audiological tests such as OAE (otoacoustic emission), ABR (auditory brainstem response), BOA (behavioural audiometry), and PTA (puretone audiometry) to comprehensively assess the children's hearing abilities. Blood samples were collected and analyzed using ELISA for detecting antibodies against Toxoplasma, Rubella, Cytomegalovirus (CMV), and Herpes Simplex Virus (HSV) (TORCH). The study found that all patients tested negative for IgM, indicating no recent infection. However, the IgG seroprevalence was significant, with 16.3% for Toxoplasma, 74.4% for Rubella, 69.8% for CMV, and 20.9% for HSV. This finding underscores the prevalence of TORCH infections in India and their potential impact on hearing development. All children exhibited bilateral severe to profound hearing loss based on ABR results and bilateral REFER (refer to equipment) on OAE, highlighting the severity of their hearing impairment.

Screening for TORCH Infections is Crucial for Early Intervention

The high prevalence of TORCH infections in India signifies their importance as a risk factor for sensorineural hearing loss. The authors emphasize the need for early identification and intervention in children with hearing loss, as this can significantly improve their prognosis and guide decision-making regarding cochlear implantation. The study highlights the need for comprehensive screening for TORCH infections in children with profound hearing loss in India. Early identification of these infections can facilitate timely intervention, potentially improving outcomes and promoting better hearing health.

Understanding the Impact of TORCH Infections on Hearing Development

TORCH infections are a significant threat to hearing development, especially in children. The study's findings serve as a wake-up call for healthcare professionals and policymakers in India to prioritize screening for these infections. The study's findings underscore the importance of early identification and treatment of TORCH infections in children with hearing loss. Implementing effective screening programs and prompt interventions can pave the way for improved hearing outcomes and a brighter future for these children.

Dr.Camel's Conclusion

Just like a camel navigating a vast desert, understanding the causes of hearing loss in children requires a comprehensive approach. The authors of this study used a camel train of tests – OAE, ABR, BOA, and PTA – to map the terrain of hearing impairment. Their findings are like an oasis in the desert, offering valuable insights into the role of TORCH infections in hearing loss. This study is a valuable resource for healthcare professionals in India and highlights the importance of early intervention in improving the lives of children with hearing loss.
