thrombocytopenic purpura

Mohammad Abu-Hishmeh, Alamgir Sattar, Fnu Zarlasht, Mohamed Ramadan, Aisha Abdel-Rahman, Shante Hinson, Caroline Hwang
BACKGROUND Thrombotic thrombocytopenic purpura (TTP) is one of the thrombotic microangiopathic (TMA) syndromes, caused by severely reduced activity of the vWF-cleaving protease ADAMTS13. Systemic lupus erythematosus (SLE), on the other hand, is an autoimmune disease that affects various organs in the body, including the hematopoietic system. SLE can present with TMA, and differentiating between SLE and TTP in those cases can be very challenging, particularly in patients with no prior history of SLE. Furthermore, an association between these 2 diseases has been described in the literature, with most of the TTP cases occurring after the diagnosis of SLE...

BACKGROUND: The secondary forms of hemolytic uremic syndrome/thrombotic thrombocytopenic purpura (secondary TMA) emerge as complications of coexisting diseases. OBJECTIVES: We hypothesized that secondary TMA could be characterized by the presence of relative ADAMTS13 deficiency and complement activation, and this relationship may have a prognostic value for outcome. PATIENTS AND METHODS: Fifty-three patients with thrombotic microangiopathy (TMA) and coexisting disease (such as malignancies, sepsis, heart surgery with extracorporeal circulation, solid organ transplantation, systemic autoimmune disorders), 41 patient controls, and 34 healthy controls were enrolled in our case-control study with 30days follow-up...

BACKGROUND: Thrombotic thrombocytopenic purpura (TTP) is a microangiopathic hemolytic anemia that requires emergent treatment with plasma exchange and is one of the most important conditions for which apheresis service professionals are consulted. Careful interpretation of initial laboratory values and the peripheral blood smear is a critical first step to determining the need for plasma exchange because other conditions can show deceptively similar red cell morphology, and ADAMTS13 levels are often not rapidly available...

BACKGROUND: Acquired thrombotic thrombocytopenic purpura (TTP) is a rare, life-threatening thrombotic microangiopathy associated with the development of autoantibodies against the von Willebrand factor cleaving protease, ADAMTS13. Similarly to other autoimmune disorders, evidences of a genetic contribution have been reported, including the association of the human leukocyte antigen (HLA) class II complex with disease risk OBJECTIVE: To identify novel genetic risk factors in acquired TTP...

Accessory splenectomy should be considered in any patient with recurrence of immune thrombocytopenic purpura, if studies (scintigraphy using heat-damaged Tc99m-labeled red blood cells) are suggestive of residual functional splenic tissue. The most common benefit after removal of accessory spleen seems to be the reduction of dose in medical treatment.

We review the most characteristic clinical and histopathologic findings of the cutaneous manifestations of the occlusive nonvasculitic vasculopathic disorders. Clinically, most of these conditions are characterized by retiform purpura. Histopathologic findings consist of occlusion of the vessel lumina with no vasculitis. Different disorders may produce nonvasculitic occlusive vasculopathy in cutaneous blood and lymphatic vessels, including embolization due to cholesterol and oxalate emboli, cutaneous intravascular metastasis from visceral malignancies, atrial myxomas, intravascular angiosarcoma, intralymphatic histiocytosis, intravascular lymphomas, endocarditis, crystal globulin vasculopathy, hypereosinophilic syndrome, and foreign material...

The study aimed to investigate the long-term outcomes of laparoscopic splenectomy (LS) in Chinese patients with chronic idiopathic thrombocytopenic purpura (ITP). This was a retrospective analysis of 114 patients with ITP who underwent LS from 2001 to 2013. Patients were classified according to response at last contact: complete response (CR), partial response (PR), and no response (NR). Patients with CR had the highest platelet levels and patients with NR had the lowest. A correlation was observed between postoperative peak platelet count and platelet count on 2-month postoperative (r=0...

A 64 year-old woman with steroid-dependent immune thrombocytopenia developed anemia. Esophagogastroduodenoscopy revealed the presence of a tumor, which was diagnosed to be diffuse large B-cell lymphoma, in the second portion of the duodenum. (18)F-fluorodeoxy glucose positron emission tomography showed an increased uptake mass in the pelvic cavity as well as in the duodenum. Though the duodenal tumor disappeared after 4 cycles of chemotherapy, the pelvic mass did not shrink in size. As a result, laparoscopic resection of the pelvic tumor was performed and the tumor was histologically diagnosed to be a gastrointestinal stromal tumor...

Endothelial cells (EC) respond to injury by releasing numerous factors, including von Willebrand factor (VWF). High circulating levels of unusually large VWF multimers (UL-VWFM) have strong procoagulant activity and facilitate platelet adhesion and aggregation by interacting with platelets after an acute event superimposed on peripheral arterial disease and coronary artery disease. ADAMTS13-a disintegrin-like metalloproteinase with thrombospondin motif type 1 member 13-regulates a key physiological process of coagulation in the circulation by cleaving VWF multimers into small, inactive fragments...

INTRODUCTION: Corticosteroids are still the standard first-line treatment for immune thrombocytopenic purpura (ITP). As second-line therapy, splenectomy and Rituximab are both recommended. The aim of our study was to compare the efficacy of Rituximab to splenectomy in persistent or chronic ITP patients. METHODS: Between January 1999 and March 2015, we retrospectively selected all consecutive patients who underwent an ITP second-line treatment: Rituximab or splenectomy...

OBJECTIVE: To identify the hematological manifestations and its association with serum ferritin levels in SLE patients from Western India. METHODS: Ninety clinically diagnosed SLE patients fulfilling ACR criteria were included. Disease activity was assessed at the time of evaluation using Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). Sera were tested for serum ferritin levels by ELISA (Calbiotech, USA). Autoantibodies such as ANA, anti-dsDNA by indirect immunofluorescence test (IFA- Bio-Rad, USA) and anti-cardiolipin antibodies (ACA) to IgG and IgM isotypes and Anti-β2 GP antibodies to IgG and IgM isotypes were detected by ELISA using commercially available kits (Euroimmun, Lubeck, Germany)...

Thrombotic microangiopathy (TMA) syndromes represent a spectrum of illnesses that share common clinical and pathologic features of microangiopathic hemolytic anemia, thrombocytopenia, and organ injury from pathologic small-vessel thrombosis. At least nine primary TMA syndromes have been described and classified based on common probable etiologies, diagnostic criteria, and treatments. The most recognized of the TMA syndromes include thrombotic thrombocytopenic purpura (TTP) and hemolytic-uremic syndrome (HUS)...

BACKGROUND: The authors wished to develop a scoring system for evaluating patients presenting with febrile thrombocytopenia for risk stratification, predicting patient outcome and optimization of care especially in resource poor countries. OBJECTIVE: 1. To decide a protocol in the management of patients with fever and thrombocytopenia. 2. To develop screening or therapeutic guidelines (early warning score-EWS) in febrile thrombocytopenic patients and decide about therapeutic interventions...
