OBJECTIVE To evaluate whether activated partial thromboplastin time (APTT) could be used in the laboratory diagnosis of hereditary or acquired angioedema (HAE or AAE) with and without C1 inhibitor (C1-INH) deficiency. METHODS In a prospective investigation, APTT and other coagulation parameters were determined in 149 adult patients with various types of angioedema and in 26 healthy participan...

Introduction: The goal of our study was to develop a risk-oriented algorithm for the combined use hemostatics and anticoagulants in patients after total arthroplasty knee or hip joints reduce risk thrombohemorrhagic complications.
 Materials methods: We performed retrospective (n=253). In group (Gr.) 1, time interval (TI) between administration hemostatic anticoagulant prophylaxis ≤17 hour...

A wide variety of animal models on thrombosis and hemostasis are used in research for the preclinical assessment hemostatic agents. While vertebrate coagulome is highly conserved, human plasmas differ considerably when evaluated coagulation assays such as prothrombin time (PT), activated partial thromboplastin (APTT), calibrated automated thrombography (CAT). Here, we have aimed to provide a re...

BACKGROUND Argatroban or lepirudin anticoagulation therapy in patients with heparin induced thrombocytopenia (HIT) or HIT suspect is typically monitored using the activated partial thromboplastin time (aPTT). Although aPTT correlates well with plasma levels of argatroban and lepirudin in healthy volunteers, it might not be the method of choice in critically ill patients. However, in-vivo data i...

Dabigatran is an oral direct thrombin inhibitor (DTI) licensed for stroke prevention in atrial fibrillation and likely to be soon approved in Europe for treatment of venous thrombosis. Predictable pharmacokinetics and a reduced risk of intracranial haemorrhage do not negate the potential risk of haemorrhage. Unlike warfarin, there is no reversal agent and measurement of the anticoagulant effect...

Acquired hemophilia is a rare disorder caused by autoantibodies to factor VIII (FVIII) (also referred to as factor VIII inhibitors or anti-FVIII) and may be associated with pregnancy, underlying malignancy, or autoimmune disorders. A 33-month-old girl who presented with hematochezia and ecchymotic skin lesions was diagnosed with Mycoplasma pneumoniae pneumonia by serology and polymerase chain r...

INTRODUCTION The most commonly used test for monitoring heparin therapy is the activated partial thromboplastin time (aPTT). The response of available aPTT reagents to heparin varies significantly. The aim of this study was to highlight the differences between aPTT reagents stored in a dried format to select the most suitable formulations to be used for the development of point-of-care diagnost...

Objectives—To investigate the hemostatic status of critically ill, nonbleeding trauma patients. We hypothesized that a hypercoagulable state exists in patients early after severe injury and that the pattern of clotting and fibrinolysis are similar between burned and nonburn trauma patients. Materials and Methods—Patients admitted to the surgical or burn intensive care unit within 24 hours after...
