Infants are at platelets (consider addition of IvIg) should be given. Neonatal alloimmune thrombocytopenia (NAIT) is a common but significant challenge for neonatologists and a potentially devastating disease that may lead to intracranial bleeding. Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a severe, but rare disorder that affects about 1 in 1000 newborns [].It is characterized by the destruction of fetal platelets by maternal antibodies directed against paternally inherited platelet antigens [].The major causative antigen in Caucasians is the human platelet antigen 1a (HPA-1a), but more than 30 … Epub 2013 Feb 6. Fetal and neonatal alloimmune thrombocytopenia (FNAIT) may result in severe bleeding, particularly fetal and neonatal intracranial haemorrhage (ICH). doi: 10.1136/bcr-2014-204393. Fetal and neonatal alloimmune thrombocytopenia (FNAIT) may result in severe bleeding, particularly fetal and neonatal intracranial haemorrhage. Diagnostic testing for NAT involves genotyping of maternal, paternal, and sometimes fetal DNA; platelet antigen phenotyping; and maternal platelet antibody investigations using specialized platelet glycoprotein specific assays. Clipboard, Search History, and several other advanced features are temporarily unavailable. thrombocytopaenia. Epub 2019 Apr 9. 2014;54:640�5. Although many cases are mild, NAIT is a significant cause of morbidity and mortality in newborns and is the most common cause of … E. A. Letsky. Blood. Orphanet J Rare Dis. Evidence-based information on Neonatal alloimmune thrombocytopenia from hundreds of trustworthy sources for health and social care. Management of infants born with severe neonatal Jerónimo M, Azenha C, Mesquita J, Pereira DF. A history of Neonatal Alloimmune Thrombocytopenia or NAIT is not common, but can have devastating complications. Infants are at significant risk of ICH in the first days of life. Healthy infants born to healthy mothers can unexpectedly develop bleeding within the first 72 hours of life. If platelet transfusion is needed, ring haematologist on call to Improvements in our understanding of the pathophysiology of NAT, and of clinical and laboratory predictors of severity, may help develop better treatments and improve our ability to identify mothers at risk. This is the most important cause of thrombocytopenia … Am J Perinatol. Maori, for HPA -4b among Asians, and for HPA-6b among Polynesians. As a result, FNAIT requires prompt identification and treatment; subsequent pregnancies need close surveillance and management. 2013 Apr;161(1):3-14. doi: 10.1111/bjh.12235. 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. NLM These antibodies can cause intracranial hemorrhage (ICH) or other major bleeding resulting in lifelong handicaps or death. Other postnatal complications have been reported such as thrombocytopenia, iron overload and cholestasis requiring specific management. Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a disease in pregnancy characterized by maternal alloantibodies directed against the human platelet antigen (HPA). Antenatal management in fetal and neonatal alloimmune thrombocytopenia: a systematic review. Opti … We report severe recurrent NAIT related to human platelet antigen … FBC: normal platelet count during pregnancy. Guidelines on the investigation and management of thrombocytopenia in pregnancy and also on the management of neonatal alloimmune thrombocytopenia have recently been prepared on behalf on the Maternal and Neonatal Haemostasis Working Party and the Haemostasis and Thrombosis … Incompatibilities between maternal and fetal platelets for the human platelet antigen 1a (previously called PL(A1)) account for most of the patients with NAT, but other antigens are commonly implicated.

A French working group comprising 50 members from 3 countries recently developed a set of practice guidelines for managing neonatal thrombocytopenia (NNT) in the context of suspected or confirmed fetal and neonatal alloimmune thrombocytopenia (FNAIT). The underlying mechanism of thrombocytopenia is expected to be mediated by accelerated clearance of antibody-opsonized fetal platelets. significant risk for ICH in the first days of life. petechiae, but the spectrum of disease ranges from sub-clinical moderate The commonest mode of presentation is the well neonate with bruises or If transfusion is needed, discuss the case with a clinical At the time, the need for further review was acknowledged by Source: Winkelhorst D, Murphy MF, Greinacher A, et al.
