Hemorrhagic fever with renal syndrome in Korea (Korean hemorrhagic fever) is an acute viral disease characterized by fever, hemorrhage and renal failure. In Korean patients, the disease manifests more distinctive bleeding tendencies than those of hemorrhagic fever with renal syndrome found in western countries. To investigate the nature and role of the coagulation, fibrinolysis, kinin and immune system in the pathogenesis of such a hemorrhagic manifestation, alterations of these systems were assessed from the early phase of the disease. ⋯ Significant decrease of serum C3 was evident in the patients with disseminated intravascular coagulation. These findings of coagulopathy were normalized within ten days of the illness in most cases. Therefore, it can be concluded that disseminated intravascular coagulation and thrombocytopenia in the early phase, and azotemia developing later might play an important role in the pathogenesis of bleeding tendency in Korean hemorrhagic fever.
