A well infant who presents unexpectedly on the first day of life with extensive bruising and/or a petechial rash and who is found to have isolated thrombocytopenia (platelet count <100 x 109/L) without an obvious cause must be presumed to have neonatal alloimmune thrombocytopenia until proven otherwise.

Bussel JB, Berkowitz RL, McFarland JG. Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a disorder in which maternal-fetal platelet incompatibility leads to formation of maternal antibodies that result in fetal and neonatal thrombocytopenia.

Neonatal alloimmune thrombocytopenia (NAIT) is a disorder caused by feto-maternal platelet incompatibility analogous to that in Rhesus Haemolytic Disease, with maternal anti-platelet antibodies crossing the placenta and destroying fetal platelets. Detection and identification of platelet antibodies and antigens in the clinical laboratory. The diagnosis is made serologically by showing parental platelet … During pregnancy, the mother produces antibodies that attack and destroy platelets, resulting in severe thrombocytopenia (low platelet count) and bleeding in the fetus. Feto-maternal incompatibility in the human platelet anti-gen 1 (HPA 1) system is the most common cause of NAIT. Also Known as. FNAIT, NAIT, NATP. NAIT results in the destruction of platelets in the fetus or infant due to a mismatch between the mother’s platelets and those of the baby. Neonatal Alloimmune Thrombocytopenia: Antenatal and Postnatal Imaging Findings in the Pediatric Brain Sonia T. Dale and Lee T.

Ahmed El Melhat Registrar NICURegistrar NICU Under Supervision of Dr. Mohamed El Sunni Consultant NICU 2. Thrombocytopenia presenting in the first 72 hours of life is usually secondary to placental insufficiency and caused by reduced platelet production; fortunately most episodes are mild or moderate and resolve spontaneously.

Neonatal alloimmune thrombocytopenia (NAITP, NAIT, NATP or NAT) is a disease that affects babies in which the platelet count is decreased because the mother's immune system attacks her fetus' or newborn's platelets.A low platelet count increases the risk of bleeding in the fetus and newborn.

Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a relatively rare but potentially lethal disease, leading to severe bleeding complications in 1 in 11.000 newborns. Platelet function remains relatively normal. Neonatal alloimmune thrombocytopenia (NAIT) In NAIT, the platelet equivalent of haemolytic dis-ease of the newborn, thrombocytopenia results from transplacental passage of maternal antibodies to fetal platelets expressing paternal human plate-let antigens (HPA) that the mother lacks.
