This syndrome was first reported back in 1973... |
Vascular leak syndrome(VLS) is characterized by endothelial damage, which causes extravasation of plasma proteins and fluid from capillaries into the extravascular space. It has been suggested that the increased vascular permeability is the result of an IL-2-induced suppression of endothelin- 1 secretion by endothelial cells, an IL-2-induced activation of the complement cascade or TNF-αrelease from IL-2-activated T-cells. A 13-year-old male patient visited our hospital... |
