TTP was initially described by Eli Moschcowitz at the Beth Israel Hospital in New York City in 1924. [53] [62] Moschcowitz ascribed the disease (incorrectly, as now known) to a toxic cause. Moschcowitz noted his patient, a 16-year-old girl, had anemia, small and large bruises, microscopic hematuria, and, at autopsy, disseminated microvascular ...

Some women may have heavier or longer periods or breakthrough bleeding. Bruising, particularly purpura in the forearms and petechiae in the feet, legs, and mucous membranes, may be caused by spontaneous bleeding under the skin. [8] [9] Eliciting a full medical history is vital to ensure the low platelet count is not secondary to another disorder.
Upshaw–Schulman syndrome (USS) is the recessively inherited form of thrombotic thrombocytopenic purpura (TTP), a rare and complex blood coagulation disease. USS is caused by the absence of the ADAMTS13 protease resulting in the persistence of ultra large von Willebrand factor multimers (ULvWF), causing episodes of acute thrombotic microangiopathy with disseminated multiple small vessel ...
When women experience recurrent pregnancy loss secondary to thrombophilia, some studies have suggested that low molecular weight heparin reduces the risk of miscarriage. When the results of all studies are analysed together, no statistically significant benefit could be demonstrated.
Some women with autoimmune diseases may have problems getting pregnant. This can happen for many reasons such as medication types or even disease types. [59] Tests can tell if fertility problems are caused by an autoimmune disease or an unrelated reason. Fertility treatments are able to help some women with autoimmune disease become pregnant. [2]
Older terminology distinguishes between two forms of heparin-induced thrombocytopenia: type 1 (mild, nonimmune mediated and self-limiting fall in platelet count) and type 2, the form described above. Currently, the term HIT is used without a modifier to describe the immune-mediated severe form. [4]
PTP is rare, but usually occurs in women who have had multiple pregnancies or in people who have undergone previous transfusions. The precise mechanism leading to PTP is unknown, but it most commonly occurs in individuals whose platelets lack the HPA-1a antigen (old name: PL A1). The patient develops antibodies to the HPA-1a antigen leading to ...
