[Capillary fragility and some hemostatic parameters in patients with rosacea]

The aim of the study was to investigate the association between capillary fragility and some hemostatic parameters, lipid profile in patients with rosacea. 50 patients (30 women and 20 men) aged 35 to 65 years were under observation. Control group consisted of 50 healthy persons, adequate to comparison group by sex and age. To determine the resistance of the capillary, Rumpel-Leede cuff (tourniquet test) was used which consists in determining the formation of petechial hemorrhages on the skin in the area of ​​short-term increase in venous pressure. The hemostatic system was evaluated in terms of prothrombin and thrombin time. Content of fibrinogen and fibrinolytic activity of blood were determined also. The serum lipid profile was studied by means of the following parameters: total cholesterol, triglycerides, HDL (high density lipoprotein), LDL (low density lipoproteins). The survey revealed that in 25 patients the arm cuff test was positive, whereas in the control group, only 2 cases it was weakly positive. Manifestations of hypercoagulation were found in half of patients with a positive cuff test, almost in half of the patients an increased level of fibrinogen and the reduced fibrinolytic activity in blood serum has been revealed. Significant correlation with lipid metabolism have not been identified. Phenomenon of hypercoagulation in rosacea patients on the one hand suggests the existence of processes of microcoagulation, on the other hand the connection with the results of a cuff test can be used to predict the severity of the dermatosis and the possible risk for developing of cardiovascular disease.
