Abstract

Insights

Human cytomegalovirus (HCMV) hepatitis is uncommon in infants with prolonged neonatal jaundice. While widespread HCMV infection occurs in infants, it rarely causes liver disease in this context.

Area of Science:

  • Pediatrics
  • Virology
  • Hepatology

Background:

  • Prolonged neonatal jaundice can stem from diverse causes.
  • Human cytomegalovirus (HCMV) infection is a potential, though unclear, contributor to infant liver disease.

Purpose of the Study:

  • To investigate the role of HCMV in infants experiencing prolonged cholestatic neonatal jaundice.
  • To inform diagnostic and therapeutic strategies for HCMV-related neonatal conditions.

Main Methods:

  • Liver biopsy specimens from 85 infants with prolonged jaundice were analyzed using HCMV immunohistochemical staining.
  • HCMV serology (IgG and IgM) was conducted on a subset of infants.

Main Results:

  • Only one infant showed histological evidence of HCMV hepatitis confirmed by immunohistochemistry.
  • HCMV IgG antibodies were prevalent (92.3%), and IgM antibodies were detected in 39.7% of infants.

Conclusions:

  • HCMV infection is widespread in infants, with many primary infections occurring in the first year of life.
  • HCMV-induced hepatitis appears to be an infrequent cause of prolonged neonatal jaundice in this cohort.

Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Jaundice01:25

Jaundice

Jaundice, or icterus, is the yellow discoloration of the skin, sclerae, and mucous membranes. It happens when plasma bilirubin levels rise above 2.5-3 mg/dL, leading to bilirubin deposition in tissue.Bilirubin is a byproduct of hemoglobin degradation. In macrophages, hemoglobin breaks down into globin and heme. Globin is converted into amino acids, while heme is turned into biliverdin by heme oxygenase, which is then reduced to unconjugated bilirubin by biliverdin reductase.Unconjugated...
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...
Cryptococcal Meningitis01:27

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
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...
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...
