The study purpose was to report the first case of
granulocyte colony-stimulating factor (
G-CSF)-induced
capillary leak syndrome (CLS) in which serial extravascular lung water (EVLW) measurements were performed and to compare this case with previously reported cases. To identify previously reported cases, we performed a literature search, using PubMed with the following search terms: CLS, EVLW,
G-CSF,
granulocyte-macrophage colony-stimulating factor (
GM-CSF) and
stem cell transplantation and the references in the bibliographies of the papers retrieved. To obtain additional information about these cases, we contacted the authors by e-mail. We describe the case of a 68-year-old woman who developed severe CLS during
G-CSF treatment after autologous haematological
stem cell transplantation. CLS is caused by damage to the endothelial cells, resulting in extravasation of
plasma proteins and fluid from the capillaries into the extravascular space. This is illustrated by high values of EVLW and pulmonary vascular permeability, necessitating
mechanical ventilation. We found five other case reports in the literature. The white blood cell count at the onset of the CLS varied from very low (zero) to very high (90,500/mul). The symptoms began on day 5-9 of the
G-CSF treatment. All patients had
fever. Three patients were mechanically ventilated and four received
renal replacement therapy. Two patients died. Treatment with
G-CSF can induce fatal CLS. Monitoring of EVLW in patients with severe CLS may be useful to guide
fluid therapy and improve oxygenation.
