Hemoadsorption as part of a multimodal therapy concept to treat Capnocytophaga sepsis with thrombocytopenia and multiple organ failure.

This article focuses on a severe case of Capnocytophaga canimorsus infection, a bacterium commonly found in the oral flora of dogs, which led to septic shock, multiple organ failure, and coagulopathy in a 68-year-old immunocompetent male following a minor dog bite. The patient was treated successfully with a multimodal approach including broad-spectrum antibiotics, mass transfusions, continuous renal replacement therapy (CRRT), and CytoSorb hemoadsorption therapy—an extracorporeal blood purification method aimed at controlling hyperinflammation. The combined treatment resulted in rapid clinical stabilization, improved neurological status, and control of the hyperinflammatory response without complications. This case highlights the potential severity of Capnocytophaga infections even in patients without typical risk factors and suggests that adjunctive hemoadsorption therapy may be beneficial, though further research is needed to clarify its role.
