Pathophysiology of a severe case of Puumala hantavirus infection successfully treated with bradykinin receptor antagonist icatibant

Abstract

We recently described a patient with very severe Puumala hantavirus infection manifested by capillary leakage syndrome and shock. He was successfully treated with the bradykinin receptor antagonist, icatibant (Antonen et al., 2013). Here we report analysis of the pathophysiology which indicated pronounced complement activation, prolonged leukocytosis, extensive fibrinolysis, circulating histones, and defects in liver function. The patient had an uncommon HLA-phenotype, which may have contributed to the severe course of the disease.

Keywords: Bradykinin; Capillary leakage; Complement activation; Hantavirus; Icatibant; Pathophysiology.
