Abstract:
Rhesus D haemolytic disease of the newborn (RH HDN) and neonatal PlA1 alloimmune thrombocytopenia (NAT) are the main immune cytopenias affecting fetal red blood cells or platelets through maternal antibodies. During RH HDN, fetal anaemia and neonatal hyperbilirubinaemia may progress, if untreated, towards fetal death and neonatal kernicterus. Likewise, during NAT, intracranial haemorrhage may occur antenally, at delivery or postnatally. Fetal and neonatal transfusion therapy, pre-term delivery, and intensive phototherapy avoid or greatly reduce the incidence of these complications. However, the best treatment of RH HDN is to prevent primary anti-D immunisation in Rh negative pregnant women through passive immunotherapy with Rh immune globulin.

Development of Immunocompetence
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.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
