Neonatal Alloimmune Thrombocytopenia (NAIT) results from maternal human platelet antibodies (HPA) against fetal platelet antigens inherited from the father. Authors E F van Leeuwen, A E von dem Borne, A M Oudesluijs-Murphy, G J Ras-Zeijlmans. Fetal and neonatal alloimmune thrombocytopenia (NAIT) is a blood disorder that affects pregnant women and their babies. Neonatal alloimmune thrombocytopenia (NAIT) is a rare (1 of 1200 pregnancies) but potentially serious condition. Fetal and neonatal alloimmune thrombocytopenia is an uncommon but potentially serious complication of pregnancy caused by immune-mediated destruction of fetal platelets by maternal alloantibodies. The most serious potential consequence of FNAIT is intracranial hemorrhage. Several strategies can be used to manage fetal or neonatal alloimmune thrombocytopenia (FNAIT) in subsequent pregnancies.

Neonatal Alloimmune Thrombocytopenia Case Report. Neonatal alloimmune thrombocytopenia (NAIT) is a fetomaternal incompatibility most commonly induced by maternal anti-HPA-1a, IgG alloantibodies against a polymorphic epitope of the glycoprotein IIb/IIIa complex in approximately 97.5% of white patients. Neonatal Thrombocytopenia. Feto-maternal incompatibility in the human platelet anti-gen 1 (HPA 1) system is the most common cause of NAIT. Small case studies only; insufficient data (Category 4a).

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. 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. The disorder results from placental transfer of maternal alloantibodies directed against paternally inherited antigens carried on Maternal IVIG in neonatal alloimmune thrombocytopenia. It is the leading cause of thrombocytopenia in healthy term-born neonates. 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. In contrast to rhesus haemolytic disease, platelet allo-immunization can occur during the first pregnancy. Neonatal alloimmune thrombocytopenia (NAIT) is a result of platelet destruction by maternal antibodies directed against paternally-inherited antigens on fetal platelets. 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. Requisition Form: Requisition Form. Immunohematology 2009;25: 125-135. 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 ALLO-IMMUNE THROMBOCYTOPENIA (NAIT) • This is analogous to Rhesus haemolytic disease and is caused by transplacental passage of maternal alloantibodies directed against fetal platelet antigens, inherited from father but absent in mother. Neonatal Thrombocytopenia General Presentation 1 Causes and Mechanisms 1 Classification 2 Clinical Presentation and Diagnosis 3 a. 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. Clinical recognition of neonatal alloimmune thrombocytopenia (NAIT) can be more difficult and masked by other presenting clinical signs in the neonate such as weakness or inability to nurse as a result of neonatal encephalopathy or sepsis (Buechner‐Maxwell et al. During pregnancy, the mother produces antibodies that attack and destroy platelets, resulting in severe thrombocytopenia (low platelet count) and bleeding in the fetus. Neonatal Alloimmune Thrombocytopenia: Antenatal and Postnatal Imaging Findings in the Pediatric Brain Sonia T. Dale and Lee T. Coleman BACKGROUND AND PURPOSE: Neonatal alloimmune thrombocytopenia (NAIT) is a ma-ternal-fetal platelet antigen incompatibility disorder estimated to occur in one of 2000 to 5000 neonates. Br J Haematol. Platelet function remains relatively normal. Serial fetal blood sampling (FBS) and intrauterine platelet transfusions (IUPT), as well as weekly maternal IV immunoglobulin infusion (IVIG), with or without additional corticosteroid therapy, are common options, but optimal management has not been determined. These antibodies can cause intracranial hemorrhage (ICH) or other major bleeding resulting in lifelong handicaps or death. … [Article in French] Muller JY, Patereau C, Reznikoff-Etievant MF, Kaplan C, Simonney N. 88 families in which 84 cases of neonatal alloimmune thrombocytopenia (NAT) occurred, were studied. NAIT was first reported in the literature in 1953 and is estimated to occur in as many as 1 in 1200 live births.
