Insights

Weekly human normal immunoglobulin injections reduced infection episodes in premature infants. While not preventing initial infections, it lowered overall severity and mortality, suggesting potential benefits for vulnerable newborns.

Area of Science:

  • Neonatal Medicine
  • Immunology
  • Pediatric Infectious Diseases

Background:

  • Premature infants, especially those with gestational age of 32 weeks or less, are highly susceptible to infections.
  • Immune system immaturity in preterm neonates increases the risk of severe infections and related complications.
  • Human normal immunoglobulin (HNIG) is explored as a potential prophylactic or therapeutic agent in vulnerable populations.

Purpose of the Study:

  • To evaluate the efficacy of weekly intramuscular human normal immunoglobulin (HNIG) in preventing and reducing the severity of infections in premature infants.
  • To assess the impact of HNIG administration on infection rates, mortality, and specific neonatal morbidities like necrotising enterocolitis.

Main Methods:

  • An open study involving 120 premature infants (≤32 weeks gestation) randomized to receive weekly intramuscular injections of HNIG (50 mg/kg) or no treatment.
  • Monitoring of infection episodes, mortality, necrotising enterocolitis, and serum IgG concentrations throughout the study period.

Main Results:

  • No significant difference in the incidence of at least one infection episode between treated (n=22) and untreated groups.
  • A substantial reduction in the total number of infective episodes in the HNIG-treated group (22) compared to the untreated group (40).
  • Fewer deaths from overwhelming infection and cases of necrotising enterocolitis were observed in the HNIG-treated group.

Conclusions:

  • Administration of human normal immunoglobulin may decrease the severity of infections in premature infants.
  • While HNIG did not significantly prevent the occurrence of infections, it appeared to reduce their frequency and impact.
  • Alternative immunoglobulin regimens might be more successful in improving outcomes for premature neonates.

Overview
Transcytosis of IgG01:15

Transcytosis of IgG

Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
Development of Immunocompetence01:22

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency disorders...
Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Respiratory Syncytial Virus Disease01:29

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
