Hemostatic changes in vasculitides.

The systemic vasculitides are an heterogeneous group of rare diseases characterized by inflammation and fibrinoid necrosis of blood vessel walls. Today it is well known that the inflammatory process characterizing vasculitides activates coagulation factors, inhibits anticoagulant factors, inhibits fibrinolytic processes, increases platelet activity and production and determines endothelial dysfunction. So far the mortality in vasculitides, even if falling, remains substantially high.

Haemostatic effects of phytoestrogen genistein in postmenopausal women.

Introduction: Genistein is an isoflavone phytoestrogen derived from the soybean which acts as natural selective estrogen receptor modulator. Various studies have pointed out its cardioprotective role. The aim of the study was to evaluate the haemostatic effects of genistein in postmenopausal women.

Long-term hemostatic effects of cholesterol-lowering therapy with atorvastatin.

This study assessed hemostatic effects of an HMC-CoA reductase inhibitor, atorvastatin, on different parameters in 32 hypercholesterolemic patients of both sexes. In the patients and in 25 control subjects, plasma levels of tissue-type plasminogen activator, plasminogen activator inhibitor (PAI-1), D-dimer, prothrombin fragment 1 + 2 (F1 + 2), total cholesterol, triglycerides and fibrinogen had been measured. All these parameters were evaluated in patients after 6 and 12 months of treatment with atorvastatin at a dosage of 20 mg/day.

Hemostasis and fibrinolysis factors in first-degree relatives of patients with Type 2 diabetes without hypertension.

First-degree relatives of type 2 diabetic patients with or without a family history of hypertension are at increased risk for cardiovascular diseases. The aim of this study was to verify some possible hemostatic alterations in first-degree relatives of type 2 diabetic, normotensive and hypertensive patients. In 78 non-diabetic, normotensive first-degree relatives of type 2 diabetic patients (47 without a family history of hypertension and 31 with a family history of hypertension) and in 36 normoglycemic, normotensive subjects with no family history of hypertension, we evaluated plasma levels of fasting glucose and insulin, tissue-type plasminogen activator (t-PA), plasminogen activator-inhibitor (PAI-1), D-dimer (DD) and prothrombin fragment 1 + 2 (F1+2).
