[Neonatal infection and high IgM at birth]

|July 1, 1978
Summary
High levels of immunoglobulin M (IgM) in newborns can indicate intrauterine infections, even without obvious symptoms. This IgM testing remains a valuable tool for early detection of congenital infections.
Area of Science:
- Neonatal immunology
- Infectious diseases
Background:
- Intrauterine infections pose significant risks to newborns.
- Clinical signs of congenital infections can be subtle or absent in early life.
Purpose of the Study:
- To evaluate the efficacy of immunoglobulin M (IgM) concentration as an indicator for intrauterine infections in neonates.
- To establish a reliable threshold for IgM as a diagnostic marker.
Main Methods:
- Analysis of sera from 2,906 newborns.
- Serological testing for evidence of infection in 199 paired sera.
- Identification of common infectious agents responsible for intrauterine infections.
Main Results:
- 19.4% of newborns exhibited high IgM concentrations.
- 21.1% of studied pair sera showed serological evidence of infection.
- 80.9% of infected neonates had no apparent clinical disturbances in the first two months.
Conclusions:
- Elevated IgM levels, detected by the used technique, are a reliable indicator of intrauterine infections.
- IgM testing is crucial for identifying infections that may present with minimal or unnoticed clinical manifestations.
- IgM testing complements, but does not replace, other clinical and laboratory investigations for diagnosing neonatal infections.
