Insights

Postnatal cytomegalovirus infection in preterm infants did not lead to sensorineural hearing loss. This study monitored hearing in 64 infants during their first year and 18 during their second year.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Audiology

Background:

  • Cytomegalovirus (CMV) is a significant cause of sensorineural hearing loss in children.
  • Congenital CMV infection's impact on hearing is well-documented, but less is known about postnatal CMV in preterm infants.

Purpose of the Study:

  • To investigate the hearing outcomes of preterm infants with postnatal cytomegalovirus infection.
  • To determine if postnatal CMV infection poses a risk for sensorineural hearing loss in this vulnerable population.

Main Methods:

  • Prospective study of 64 preterm infants with postnatal CMV infection during their first year of life.
  • Follow-up hearing assessment for 18 of these infants during their second year of life.

Main Results:

  • No cases of sensorineural hearing loss were observed in any of the studied preterm infants.
  • The findings suggest a lack of association between postnatal CMV infection and hearing impairment in this cohort.

Conclusions:

  • Postnatal cytomegalovirus infection in preterm infants may not be a significant risk factor for developing sensorineural hearing loss.
  • Further research is warranted to confirm these findings in larger, diverse populations.

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
