Thrombocytopenia affects approximately 7–10% of pregnant women and of the 7–10%, within that population; approximately 70–80% have gestational thrombocytopenia [3] Gestational thrombocytopenia is a disorder similar to immune thrombocytopenia (ITP) and is difficult to differentiate between the two disorders.

Unlike hemolytic disease of the fetus and newborn, NAIT occurs during the first pregnancy in up to 50% of cases, [1] and the affected fetuses may develop severe thrombocytopenia (<50,000 μL −1) very early during pregnancy (as early as 20 weeks gestation, consistent with the development of platelet antigens, [1] and the majority of the time ...
Generally, diseases outlined within the ICD-10 codes O00-O99 within Chapter XV: Pregnancy, childbirth and the puerperium should be included in this category. v t
The incidence of ITP in pregnancy is not well known. It may occur during any trimester of pregnancy. It is the most common cause of significant thrombocytopenia (platelets less than 100,000) in the second trimester, and it is a common cause of significant thrombocytopenia in the first and third trimesters.

Acquired thrombocytopenia may be associated with the use of certain drugs. Inspection typically reveals evidence of bleeding (petechiae or ecchymoses), along with slow, continuous bleeding from any injuries or wounds. Adults may have large, blood-filled bullae in the mouth. [10]
Consequently, differential diagnosis of these TMA diseases is essential. Both TTP and HUS are characterized by fever, anemia, thrombocytopenia, renal failure, and neurological symptoms. Generally, TTP has higher rates of neurological symptoms (≤80%) and lower rates of renal symptoms (9%) than HUS (10–20% and 90%, respectively). [38]
Another bleeding risk factor is thrombocytopenia, or decreased platelet levels, which is the most common hematological change associated with pregnancy induced hypertension. If platelet counts drop less than 100,000 per microliter the patient will be at a severe risk for inability to clot during and after delivery. [15]
Hypercoagulability in pregnancy is the propensity of pregnant women to develop thrombosis (blood clots). Pregnancy itself is a factor of hypercoagulability (pregnancy-induced hypercoagulability), as a physiologically adaptive mechanism to prevent post partum bleeding . [ 1 ]
