Leukocyte transforming agent (Epstein-Barr virus) in newborn infants and older individuals
Insights
Epstein-Barr virus (EBV) associated lymphocyte transforming agent (LTA) was detected in one newborn and a 16-day-old infant. LTA was absent in other infants and pregnant women but present in ill children and adults.
Area of Science:
- Virology
- Immunology
- Pediatrics
Background:
- Epstein-Barr virus (EBV) is a common human herpesvirus.
- The lymphocyte transforming agent (LTA) is a key component associated with EBV.
- Understanding EBV transmission and infection patterns is crucial, especially in vulnerable populations.
Purpose of the Study:
- To investigate the presence and prevalence of EBV-associated LTA in various demographic and clinical groups.
- To identify potential transmission routes and clinical manifestations of EBV infection in neonates, infants, children, and adults.
Main Methods:
- A cross-sectional study involving 443 individuals across different age groups and clinical conditions.
- Samples were collected from oropharyngeal and other clinical sites.
- Detection of LTA was performed using specific assays.
Main Results:
- Evidence of intrauterine EBV infection was found in one newborn.
- LTA was detected in a 16-day-old infant with transient hepatosplenomegaly.
- LTA was not detected in 96 other neonates and 57 infants with anomalies or illnesses.
- LTA was absent in cervical samples from 125 pregnant or postpartum women.
- LTA was detected with varying frequency in ill children, healthy adults, and patients with infectious mononucleosis.
Conclusions:
- EBV infection can occur in early infancy, with potential for intrauterine transmission.
- The prevalence of LTA varies significantly across different age groups and clinical statuses.
- Prospective studies are recommended to fully elucidate the clinicoepidemiologic patterns of EBV infection in infants and children.
Abstract:
The lymphocyte transforming agent, associated with Epstein-Barr virus, was sought in the oropharynx and other clinical sites of 443 individuals in the following groups: premature and term neonates; infants with congenital malformations or with suspected TORCH syndrome; children with various illnesses; pregnant and postpartum women; healthy adults; and patients with infectious mononucleosis. Evidence of intrauterine infection was found in one newborn infant and LTA was demonstrated in a 16-day-old infant who developed transient hepatosplenomegaly. LTA was not detected in 96 other newborn infants and 57 infants with various anomalies or illnesses; nor was it found in the cervix of 125 pregnant or postpartum women. LTA was demonstrated in varying frequency in ill children, healthy adults, and those with infectious mononucleosis. It is suggested that the clinicoepidemiologic patterns of EBV infection in newborn infants and children will best be established by prospective studies.
