This information comes from a database called the Human Phenotype Ontology We want to hear from you. There is a long list of possible reasons for thrombocytopenia in a newborn. Neonatal alloimmune thrombocytopenia (NAITP, NAIT, NATP or NAT) is a disease that affects babies in which the platelet count is decreased. Infants with very low platelet counts are screened for ICH with cranial ultrasounds. In more severely affected infants, the goal of treatment is to prevent or stop active bleeding, particularly in the brain. You can help advance (HPO). Blood is sent to a special lab to assess whether the mother and father have mismatching platelet antigens and whether the mother is making antibodies to platelet antigens found in the father. Neonatal Alloimmune Thrombocytopenia or NAIT is not common, but can have devastating complications.

These antibodies transfer from the mother to the fetus via the placenta, where they attach to platelets, marking them for destruction. Our platelets are coated with antigens, substances that induce an immune response. In these circumstances usually, the baby is quite ill. NAIT should be considered in a well-appearing infant with severe thrombocytopenia (platelet count less than 50,000 cells per microliter). The mother will have a normal platelet count, since the antibodies do not attack her platelets.
