Hemoperfusion in Leptospirosis
Abstract
Leptospirosis is the most common zoonosis frequently seen in the tropics and subtropics especially during the rainy season when humans wade in floods contaminated by the urine of infected rats in urban areas. Aside from direct toxicity of the leptospires, the role of an exuberant immune response to the pathogen leading to secondary organ damage has been recognized. Thus, our treatment protocol for patients with severe leptospirosis characterized by renal failure, acute liver injury, and lung hemorrhage now includes a short course of methylprednisolone and intravenous cyclophosphamide. In some patients, however, hemodynamic collapse and acute respiratory distress syndrome ensue, which may be due to the release of cytokines resulting from the dysregulated immune response. Blood purification in the form of hemoperfusion (HP) with neutral macroporous resin-adsorbing beads adsorbs cytokines and other inflammatory mediators leading to cardiovascular stability and stabilization of endothelial membranes. HP may be considered part of a multiorgan system therapeutic approach in diseases with reversible multiorgan failure that can lead to an improvement in patient survival.
