title: [Abnormalities of coagulation, fibrinolysis and kallikrein-kinin system in 2 cases with remarkable eosinophilia].
abstract: We evaluated an initial activation of hemostasis (coagulation, fibrinolysis and kallikrein-kinin system) in two remarkable eosinophilia cases. The first case was a 29-year-old male who complained of a high fever, general exanthema and numbness of the limbs. He had peripheral blood eosinophilia (61.075/microliters) unknown etiology, and hypereosinophilic syndrome (HES) was diagnosed. The second case was a 60-year-old female who complained of numbness in her lower limbs. She also presented eosinophilia (10,379/microliters), and had clinical features of allergic granulomatous angitis (AGA). The administration of prednisolone led to clinical remission in both cases, including rapid improvement of eosinophilia, normalization of hypercoagulability and correction of platelet dysfunction. In hemostatic parameters, the titer of the soluble fibrin monomer complex (SFMC) became negative, and each value of FDP D-dimer, fpB beta 15-42, thrombin-antithrombin III complex (TAT) decreased, whereas the value of prekallikrein increased. A decrease in platelet aggregation with ADP, collagen and epinephrine was normalized by prednisolone administration. Hemostatic data in both cases indicate a possible relationship between the initial activation of hemostasis and the eosinophils, as well as the possibility of general and/or organic inflammations and intravascular thrombi formations in eosinophilia such as HES and AGA.
