The study was performed in a group of 25 patients with acute necrotizing pancreatitis (mean age 46.2 ± 6.74 years). Gender differences of the hemostasis postagressive early response in the early stages of the disease were identified by comparing the procoagulant , anticoagulant and fibrinolytic blood activity of men and women suffering from pancreatitis. Compared to men, women showed higher concentrations of fibrinogen, D-dimer and VWF and smaller values marked trombokrit , antithrombin III, inhibitor of plasmin and protein C (p < 0.05). These results suggest a greater tendency to thrombi formation in women with acute pancreatitis; We believe that gender differences should be the subject of further research.
