Abstract In Coronavirus disease 2019 (COVID-19) subjects, recent evidence suggests the presence of unique coagulation abnormalities. this study, we performed clot waveform analyses to investigate whether specific modulations are observed in COVID-19 subjects. We analyzed second derivative absorbance routine APTT tests using an ACL-TOP system. high frequencies abnormal patterns second-derivative...

BACKGROUND In Fabry disease, storage of globotriaosylceramide (Gb3) in arterial walls is one of the main pathogenetic factors that are thought to underlie the clinical manifestations of the disease. Abnormalities of the vessel wall, haemodynamics and pro- and anticoagulant factors may play a role, though the exact pathophysiology is incompletely understood. In this study, we try to clarify inco...

OBJECTIVE To determine the coagulation abnormalities and relationship between abnormal clotting tests and the risk of gastrointestinal bleeding (GI) among chronic liver disease (CLD) patients admitted at a tertiary care hospital in Pakistan. METHODS Adult CLD patients admitted at Liaquat University Hospital Jamshoro, during Nov 2004-Oct 2005, were included in the study. The patients blood wer...

BACKGROUND Atrial thrombus formation in patients with atrial flutter raises concerns of stroke risk. We investigated patients with isthmus-dependent atrial flutter for coagulation abnormalities before and after cardioversion to sinus rhythm by catheter ablation, and evaluated the relationship of the abnormalities to the echocardiographic risk markers of stroke. METHODS AND RESULTS Plasma samp...

BACKGROUND AND PURPOSE Shifts of the balance between coagulation and fibrinolysis play a crucial role in pathogenesis and treatment of cerebral ischemia. In this study, we characterized the kinetics of hemostatic abnormalities induced by acute ischemic stroke and its thrombolytic (recombinant tissue plasminogen activator [rtPA]) or anticoagulant (heparin) treatment. METHODS Systemic generatio...

BACKGROUND Each year in the UK, ≈3000 children undergo major cardiac surgery requiring cardiopulmonary bypass. Approximately 40 % of these experience excessive bleeding necessitating red cell transfusion or treatment with other blood components. A further 40 % receive blood components because of the perception by clinicians that the risk of bleeding is high. Excessive bleeding and treatment wit...

BACKGROUND There are very few data on the prevalence of coagulation abnormalities in primary deep vein thrombosis of the upper limbs. OBJECTIVE To determine if coagulation abnormalities play a role in effort-related and/or idiopathic (non-effort-related) upper-extremity deep vein thrombosis (UEDVT). METHODS Fifty-one consecutive patients (21 men and 30 women) who had effort-related (n = 20)...

An asymptomatic woman (Ms. Williams) was found to have a severe abnormality in the surface-activated intrinsic coagulation, fibrinolytic, and kinin-generating pathways. Assays for known coagulation factors were nromal while Fletcher factor (pre-kallikrein) was 45%, insufficient to account for the observed markedly prolonged partial thromboplastin time. Plasminogen proactivator was present at 20...

OBJECTIVE Benign intracranial hypertension (BIH) may be caused by intracranial venous sinus thrombosis. Cerebral angiograms may, however, be normal in patients with BIH that are associated with conditions with an increased risk of venous thrombosis. This raises the possibility that unrecognised non-occlusive venous thrombus might impede CSF drainage. This study therefore examined the strength o...

The results of twenty-four ascitic reinfusions in twenty patients, using the Rhodiascit procedure, are reported. The procedure was of no value in the management of patients with spontaneous functional renal failure, but was of considerable value in accelerating hospital discharge of patients with tense ascites but good renal function. Complications of the procedure were few, but tests of blood ...
