| Abstract |
| We report a case of capillary leak syndrome in a 37-year-old female PBPC donor who received G-CSF 900  g/day for 4 days and underwent leukapheresis. This lady had remained well and stable despite marked leukocytosis during G-CSF treatment, but developed hypotension during leukapheresis, quickly followed by hypoxemia, ascites, pericardial and pleural effusion, shock, edema, neurologic changes and hepatocellular injury. Upon G-CSF withdrawal, dopamine and crystalloid infusion, methylprednisolone treatment and suspension of apheresis, the clinical situation fully reversed. We hypothesize that leukapheresis, in the presence of marked leukocytosis and high doses of G-CSF, may have triggered neutrophil activation and the release of inflammatory mediators, resulting in tissue damage and systemic manifestations of increased capillary permeability.
