Birth characteristics and growth pattern in children with congenital cytomegalovirus infection

Area of Science:

• Pediatrics
• Infectious Diseases
• Developmental Biology

Background:

• Congenital cytomegalovirus (CMV) infection is a common cause of non-genetic sensorineural hearing loss and developmental disabilities.
• The long-term impact of congenital CMV infection on growth patterns, particularly height and weight, requires further investigation.

Purpose of the Study:

• To compare the birth characteristics and growth patterns of children with congenital CMV infection against Swedish reference data.
• To investigate potential differences in growth based on infection type (primary vs. reactivated congenital CMV).

Main Methods:

• Retrospective analysis of 76 children diagnosed with congenital CMV infection.
• Classification of infection into primary, reactivated, or undetermined based on maternal serology.
• Comparison of height, weight, and growth trajectories with Swedish reference data up to a median follow-up of 10 years.

Main Results:

• No significant overall differences in height and weight were observed between children with congenital CMV infection and the reference standard.
• Children with primary congenital CMV infection showed borderline shorter stature at 1-2 years.
• Children with reactivated congenital CMV infection were taller than the reference standard from 4 years of age onwards.

Conclusions:

• Congenital CMV infection, in general, does not lead to short stature.
• Growth patterns can vary, with some subgroups potentially exhibiting accelerated growth later in childhood.
