Development of Immunocompetence01:22

Development of Immunocompetence

298
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...

Teratogenicity01:07

Teratogenicity

2.4K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Blood Transfusion and Agglutination

10.8K
Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Transcytosis of IgG01:15

Transcytosis of IgG

2.7K
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...

Summary

Hemolytic disease of the fetus and newborn (HDFN) caused by Kell alloimmunization can lead to severe fetal anemia and hydrops fetalis. This case demonstrates successful management of recurrent K-HDFN, preventing further pregnancy loss.

Area of Science:

  • Immunology
  • Obstetrics
  • Hematology

Background:

  • Hemolytic disease of the fetus and newborn (HDFN) arises from maternal antibodies targeting fetal red blood cell antigens.
  • Kell alloimmunization, specifically anti-K (KEL1), is a significant cause of severe fetal anemia and hydrops fetalis.
  • Previous pregnancies complicated by K-HDFN carry a high risk for recurrence.

Observation:

  • A pregnant woman experienced three prior pregnancy losses due to hydrops fetalis attributed to Kell alloimmunization.
  • K-HDFN was confirmed postnatally in her most recent pregnancy.

Findings:

  • Successful management of Kell alloimmunization was achieved in this high-risk pregnancy.
  • This case highlights the potential for positive outcomes despite a history of severe, recurrent K-HDFN.

Implications:

  • Effective management strategies for Kell alloimmunization can prevent fetal anemia and hydrops fetalis.
  • This case underscores the importance of early detection and intervention for Kell alloimmunization in pregnancy.
  • Successful management offers hope for women with a history of recurrent K-HDFN.
