Neonatal alloimmune thrombocytopenia
Neonatal Alloimmune Thrombocytopenia (NAT) (pronunciation: nee-oh-nay-tal al-oh-im-yoon throm-bo-sigh-toe-pee-nee-uh) is a rare but potentially serious condition that can affect newborns.
Etymology
The term "Neonatal Alloimmune Thrombocytopenia" is derived from several roots. "Neonatal" comes from the Latin neo meaning "new", and natal meaning "birth". "Alloimmune" is derived from the Greek allos meaning "other", and immune referring to the immune system. "Thrombocytopenia" comes from the Greek thrombos meaning "clot", kytos meaning "cell", and penia meaning "deficiency".
Definition
Neonatal Alloimmune Thrombocytopenia is a condition where the pregnant mother's immune system produces antibodies that attack the baby's platelets, leading to a low platelet count (thrombocytopenia) in the baby. This can cause bleeding problems in the baby, both before and after birth.
