BACKGROUND: Congenital thrombotic thrombocytopenic purpura (TTP) may not be recognized until organ failure related to the microvascular thrombosis occurs. Kidney failure may be the initial presenting clinical feature. Kidney transplantation has been contraindicated because of the assumption that the continuing microvascular thrombosis will cause inevitable graft failure. CASE REPORT: We report a 48-year-old nulliparous woman who presented with end-stage kidney disease that was attributed to hypertension...

Using the French Hemovigilance Network database from 2007 to 2013, we provide information on demographics, incidence, and risk factors of reported transfusion-related acute lung injury (TRALI) and possible TRALI, analyze TRALI mitigation efforts for fresh frozen plasma and platelet concentrates, and consider the impact of platelet additive solutions on TRALI incidence. We applied the Toronto consensus conference definitions for TRALI and possible TRALI. Two TRALI subgroups were considered: "antibody positive" when a donor has human leukocyte antigen (class I or II) and/or human neutrophil antigen antibodies and the recipient has cognate antigen, and "antibody negative" when immunological investigation is negative or not done...

CONTEXT: Thrombotic microangiopathy syndrome or thrombotic thrombocytopenic purpura-hemolytic uremic syndrome (TTP-HUS) describes distinct diseases sharing common pathological features: microangiopathic hemolytic anemia and thrombocytopenia, without any other apparent cause. CASE REPORT: An 18-year-old second-trimester primigravida presented with a history of fifteen days of intense weakness, followed by diarrhea over the past six days. She reported having had low platelets since childhood, but said that she had never had bleeding or menstrual abnormalities...

Recent studies suggest that platelet transfusions are harmful in patients with thrombotic thrombocytopenic purpura, an entity of thrombotic microangiopathies. As the typical or Shiga toxin-producing Escherichia coli-induced hemolytic uremic syndrome (STEC-HUS) is also classified as thrombotic microangiopathy, we complement these data with an analysis of 250 patients from the German O104:H4 STEC-HUS outbreak. The effect of platelet transfusion in 44 patients who received platelet transfusions vs 206 control patients was investigated...

We sought to determine the effects of exogenous administration of human coagulation factors following pig-to-baboon liver xenotransplantation (LXT) using GalT-KO swine donors. After LXT, baboons received no coagulation factors (historical control, n = 1), bolus administration of a human prothrombin concentrate complex (hPCC; 2.5 mL/kg, n = 2), continuous infusion of hPCC (1.0 mL/h, n = 1) or continuous infusion of human recombinant factor VIIa (1 µg/kg per hour, n = 3). The historical control recipient demonstrated persistent thrombocytopenia despite platelet administration after transplant, along with widespread thrombotic microangiopathy (TMA)...

Thrombocytopenia is a common problem in cancer patients. Aside from bleeding risk, thrombocytopenia limits chemotherapy dose and frequency. In evaluating thrombocytopenic cancer patients, it is important to assess for other causes of thrombocytopenia, including immune thrombocytopenia, coagulopathy, infection, drug reaction, post-transfusion purpura, and thrombotic microangiopathy. The incidence of chemotherapy-induced thrombocytopenia varies greatly depending on the treatment used; the highest rates of this condition are associated with gemcitabine- and platinum-based regimens...

Hyaluronan is a major component of the extracellular matrix and glycocalyx. Its main somatic degrading enzymes are hyaluronidases 1 and 2, neither of which is active in the bloodstream. We generated hyaluronidase 2-deficient mice. These animals suffer from chronic, mild anemia and thrombocytopenia, in parallel with a 10-fold increase in plasma hyaluronan concentration. In this study we explored the mechanism of these hematologic anomalies. The decreased erythrocyte and platelet counts were attributed to peripheral consumption...

The complex relation between thrombotic thrombocytopenic purpura (TTP) and pregnancy is concisely reviewed. Pregnancy is a very strong trigger for acute disease manifestation in patients with hereditary TTP caused by double heterozygous or homozygous mutations of ADAMTS13 (ADisintegrin And Metalloprotease with ThromboSpondin type 1 domains, no. 13). In several affected women disease onset during their first pregnancy leads to the diagnosis of hereditary TTP. Without plasma treatment mother and especially fetus are at high risk of dying...

Antiphospholipid syndrome (APS) is an autoimmune disease characterized clinically by the occurrence of venous or arterial thrombosis, and/or pregnancy morbidity. The detection of persistently elevated levels of antiphospholipid antibodies (aPL) is a requisite laboratory feature for the diagnosis of APS. The positivity for at least one aPL test: lupus anticoagulant and/or IgG/IgM anticardiolipin and/ or IgG/IgM anti-β2 glycoprotein I antibodies must be detected. Sometimes aPL coagulopathy may start with a hemorrhagic syndrome when a severe thrombocytopenia, or an acquired thrombocytopathy, or an acquired factor VIII inhibitor, or an acquired prothrombin deficiency is present...

We present the case of a 62-year-old man with a history of Wegener granulomatosis who developed chronic thrombotic microangiopathy attributed to gemcitabine chemotherapy. Wegener granulomatosis had been diagnosed 15 years earlier, and the patient was treated using cyclophosphamide and prednisone, then maintained on mycophenolate mofetil and prednisone. Four years previously, he had been treated with mitomycin C for urothelial carcinoma and at the time of presentation had developed significant anemia and thrombocytopenia after a course of gemcitabine and carboplatin due to metastasis of the carcinoma...

Disseminated intravascular coagulopathy (DIC) is characterized as activation of the clotting system resulting in fibrin thrombi, gradually diminishing levels of clotting factors with increased risk of bleeding. Basically two types of DIC are distinguished: (1) chronic (compensated) - with alteration of laboratory values and (2) acute (non-compensated) - with severe clinical manifestations: bleeding, shock, acute renal failure (ARF), transient focal neurologic deficit, delirium or coma. Chronic DIC related to metastatic neoplasia is caused by pancreatic, gastric or prostatic carcinoma in most of the cases...

Thrombotic microangiopathies are disorders resulting from platelet thromboses forming in the microvasculature with resultant schistocyte forms. Hemolytic uremic syndrome (HUS) is a microangiopathic hemolytic anemia often complicated by acute renal failure in children. HUS is typically caused by bacterial infection, most commonly enterohemorrhagic Escherichia coli. Neuraminidase-producing organisms, such as Streptococcus pneumoniae have also been reported as potential etiologies. The pathogenesis in these cases involves cleavage of sialic acid residues from the surfaces of erythrocytes, platelets, and glomerular capillary endothelial cells, exposing the Thomsen-Friedenreich antigen, a process known as T-activation...
