Summary

Junin virus, an arenaviridae, is the etiological agent of Argentine hemorrhagic fever. In addition to thrombocytopenia, patients present several alterations in both the blood coagulation and the fibrinolytic system, but diffuse intravascular coagulation could not be demonstrated. To investigate further the activation status of the two systems, levels of thrombin-antithrombin complexes (TAT), prothrombin fragment 1+2, protein C, total and free protein S, C4bBP, antithrombin III, t-PA, PAI-1 and D-dimer were measured. Fourteen patients with a confirmed diagnosis of Argentine hemorrhagic fever were included in the study, 2 were severe, 3 moderate and 9 mild clinical cases, but hemorrhages were slight throughout. Blood samples were collected for 6 consecutive days on admission and on remission. At admission TAT and F1+2 levels were increased in 13/14 patients, reaching 0.33 nM (0.06-0.87) and 2.16 nM (0.96-6.5), respectively. PC was low in 4 cases, fPS in 6 and tPS in 2, whereas C4bBP and ATIII values were within normal range. t-PA and D-dimer levels were high in 11/14 patients, reaching 20 ng/ml (2.7-106) and 1660 ng/ml (877-3780) respectively, while PAI-1 was considerably increased in the 2 severe cases and normal in the remainder. These results suggest low level though persistent process of blood coagulation and fibrinolysis activation in this viral hemorrhagic disease. We believe these abnormalities may lead to the well described bleeding manifestations in these patients.
