Assessment of platelet function in endogenous hypercortisolism.

Introduction: It is commonly known that glucocorticoids exert a significant effect on haemostasis. Studies that have analysed the plasmatic coagulation system and fibrinolysis parameters in hypercortisolaemic patients are abundant. Platelet function, which plays a vital role in primary haemostasis, is much less clear in this context.

Activity of selected coagulation factors in overt and subclinical hypercortisolism.

It is universally acknowledged that glucocorticoids are hormones that exert a significant effect on hemostasis. The aim of this study was to analyze the activities of coagulation factors VIII, von Willebrand (vW), IX, X, and XI, in patients with overt and subclinical hypercortisolism, as well as to examine possible associations between activities of these factors and the degree of hypercortisolism. Thirty endogenous hypercortisolemic patients were included in the study.

The estimation of selected endogenous anticoagulation system parameters in patients with subclinical Cushing's syndrome.

Objective: An increased tendency towards thromboembolic events is observed in patients with Cushing's syndrome. There are much fewer publications available about thromboembolic complications in patients with subclinical Cushing's syndrome (SCS). Therefore, a question arises whether hemostatic disturbances appear in this particular disease phase.

Assessment of alpha1-antitrypsin and alpha2-macroglobulin levels in obese patients.

Introduction: Epidemiologic data show a higher frequency of thromboembolic incidents in obese individuals compared with normal weight subjects. Pro-inflammatory factors seem to play an important role in their development. It has not been fully explained so far how alpha1-antitrypsin (alpha1ATp) and alpha2-macroglobulin (alpha2MG) act in obese subjects.

[Assessment of selected haemostatic parameters in obese patients].

Background: Epidemiologic data show significantly higher frequency of thromboembolic incidents in obesity than in normal weight persons. Disorders of haemostasis seem to play a crucial role in their development. In the literature there are only few papers assessing coagulation and fibrynolitic parameters in obese subjects.

[Negative D-dimers and exclusion of venous thromboembolism--own experience].

The assessment of D-dimer concentration has become essential step during diagnostic algorithm of venous thromboembolism (VTE). This test characterizes high sensitivity but limited specificity. Negative D-dimer with high probability excludes VTE.
