Diaphragm dysfunction with congenital cytomegalovirus infection

Area of Science:

• Neonatology
• Pediatric Infectious Diseases
• Respiratory Medicine

Background:

• Congenital cytomegalovirus (CMV) infection is a common viral infection in newborns.
• CMV infection can manifest with a diverse range of clinical symptoms.
• Diaphragmatic dysfunction is a recognized but less common cause of neonatal respiratory distress.

Observation:

• This report details three cases of infants diagnosed with congenital CMV infection.
• All three infants presented with significant respiratory insufficiency.
• A common clinical feature observed was persistent diaphragmatic dysfunction.

Findings:

• Congenital CMV infection was identified as the underlying cause of respiratory insufficiency in these infants.
• Persistent diaphragmatic dysfunction was a consistent finding in infants with congenital CMV.
• This association suggests a specific pathophysiological link between congenital CMV and diaphragmatic function.

Implications:

• Congenital CMV infection should be included in the differential diagnosis for neonatal respiratory insufficiency.
• Recognition of diaphragmatic dysfunction as a potential manifestation of congenital CMV can aid in timely diagnosis and management.
• Further research is warranted to elucidate the mechanisms by which CMV affects diaphragmatic function in neonates.
