BACKGROUND Severe deficiency of ADAMTS13 activity leads to von Willebrand factor (VWF) ultralarge multimers with high affinity for platelets, causing thrombotic thrombocytopenic purpura. Other pathological conditions with moderate ADAMTS13 activity exhibit a thrombotic risk. We examined the ADAMTS13 activity in systemic lupus erythematosus (SLE) and its value as a thrombotic biomarker. METHOD...

Thrombotic adverse events (AEs) after clotting factor concentrate administration are rare but the actual rate is unknown. A systematic review of prospective studies (1990-2011) reporting safety data of factor concentrates in patients with haemophilia A (HA), haemophilia B (HB) and von Willebrand disease (VWD) was conducted to identify the incidence and type of thrombotic AEs. In 71 studies (45 ...

PURPOSE OF REVIEW The aim of this article is to assess the current understanding and uncertainties about the evaluation and management of thrombotic microangiopathy that occurs following allogeneic hematopoietic stem cell transplantation. RECENT FINDINGS Current data may not be sufficient to establish posttransplantation thrombotic microangiopathy as a discrete clinical or pathologic entity, ...

Thrombotic thrombocytopenic purpura (TTP) is a rare variant of thrombotic microangiopathy. We report case TTP in Nigerian chronic kidney disease (CKD) patient who was previously on clopidogrel. The features resolved soon after clopidogrel withdrawn. Clopidogrel cardio-protective anti-platelet drug used CKD patients at risk dyspepsia. However, its potential to cause should be recognized and cons...

Thrombotic microangiopathy, particularly the type affecting adults and usually known as thrombotic thrombocytopenic purpura, has until recently been regarded as an almost invariably fatal disease. In infancy and early childhood it is generally described as the haemolytic-uraemic syndrome. However, the latter syndrome may result from more than one pathological process, and certainly it is unknow...

INTRODUCTION Differential diagnosis of thrombotic microangiopathies can be difficult. Atypical hemolytic uremic syndrome is a rare, life-threatening disease caused by uncontrolled chronic activation of alternative complement pathway, resulting in microvascular thrombosis, organ ischemia and damage. Prognosis is poor: up to 65 percent of patients require dialysis or have kidney damage of varying...

STUDY OBJECTIVES We investigated the effects of the direct thrombin inhibitor argatroban, patient demographics, and the platelet count on thrombotic risks in heparin-induced thrombocytopenia (HIT), a serious thrombotic condition, to determine if argatroban provides effective antithrombotic therapy in patients with HIT without increasing bleeding. DESIGN We retrospectively analyzed thrombotic ...

BACKGROUND Exercise training may have the potential to improve post-thrombotic syndrome, a frequent, chronic complication of deep venous thrombosis. We conducted a randomized controlled two-centre pilot trial to assess the feasibility of a multicentre-based evaluation of a six-month exercise training program to treat post-thrombotic syndrome and to obtain preliminary data on the effectiveness o...
