Human T-cell lymphotropic virus type I infection in neonates

Summary
Neonatal transfusions can transmit human T-cell lymphotropic virus type I (HTLV-I). Three infants receiving blood transfusions tested positive for HTLV-I antibodies, indicating a transfusion-associated risk in newborns.
Area of Science:
- Virology
- Neonatal Medicine
- Infectious Diseases
Background:
- Neonatal intensive care units (NICUs) perform transfusions for various medical reasons.
- Blood transfusions carry a risk of transmitting infectious agents.
- Human T-cell lymphotropic virus type I (HTLV-I) is a retrovirus with potential health implications.
Purpose of the Study:
- To investigate the incidence of human T-cell lymphotropic virus type I (HTLV-I) infection in neonates who received blood transfusions.
- To determine if HTLV-I transmission occurred via transfusion in a neonatal population.
Main Methods:
- Serum samples from 128 transfused infants were collected.
- Enzyme-linked immunosorbent assay (ELISA) and indirect immunofluorescence test (IIFT) were used to detect anti-HTLV-I antibodies.
- Sera from mothers and siblings of seropositive infants were also tested.
Main Results:
- Three out of 128 infants (2.3%) tested positive for anti-HTLV-I antibodies.
- The seropositive infants had received varying volumes of transfused blood (62 mL, 82 mL, 1160 mL).
- No anti-HTLV-I antibodies were detected in the mothers or siblings of the infected infants, suggesting transfusion as the source.
Conclusions:
- Blood transfusions represent a potential route for HTLV-I transmission to neonates.
- Neonatal transfusion-associated HTLV-I infection is a significant concern.
- Screening of blood products for HTLV-I is crucial for preventing neonatal infections.

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.

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.

Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
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...
