      Brojer, Eva; Husebekk, Anne; Debska, Marzena; Uhrynowska, Malgorozata; Guz, Katarzyna; Orzinska, Agnieszka; Debski, Romuald; Maslanka, Krystyna (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-12)
      Fetal/neonatal alloimmune thrombocytopenia (FNAIT) is a relatively rare condition (1/1000–1/2000) that was granted orphan status by the European Medicines Agency in 2011. Clinical consequences of FNAIT, however, may be severe. A thrombocytopenic fetus or new-born is at risk of intracranial hemorrhage that may result in lifelong disability or death. Preventing such bleeding is thus vital and requires ...
