[Use of warfarin and low range INR in the prevention of recurrent venous thrombosis].

The object of this work was to determine the efficacy of a low range International Normalized Ratio (INR) between 1.5 and 1.9, in preventing recurrent venous thrombosis and the hemorrhagic manifestations that can complicate anticoagulation with warfarin.

Coagulation and inflammation markers during atypical or typical antipsychotic treatment in schizophrenia patients and drug-free first-degree relatives.

Background: Clinical studies suggest that the second generation antipsychotics (APs) clozapine and olanzapine and to a lesser extent the typical antipsychotics may be associated with a procoagulant and proinflammatory state that promotes venous thromboembolism. We evaluated here several blood factors associated with coagulation and inflammation in AP-treated schizophrenia patients and their first-degree relatives.

Methods: Procoagulant factors (fibrinogen and plasminogen activator inhibitor [PAI-1]), the anticoagulant factor antithrombin III [AT-III], and inflammation-related factors (C-reactive protein [CRP] and leptin) were assessed in patients chronically treated with clozapine (n=29), olanzapine (n=29), typical APs (n=30) and first degree relatives of clozapine (n=23) and olanzapine subjects (n=11).

[Frequency and clinical implications of lupus anticoagulant in patients with terminal chronic renal failure in hemodialysis].

The objective of the present study was to determine the frequency of lupus anticoagulant (LA), in patients with terminal chronic renal failure (TCRF), and its association with thrombotic events. Sixty three patients were separated into two groups: Group A, consisted of 32 patients under treatment with hemodialysis, and Group B was formed of 31 patients who were treated in a conservative manner. Presence of LA was found in 4 patients from Group A and none from Group B.
