Serum levels of some cytokines and soluble adhesion molecules in normal and patients with malignant malaria in Zambia.
The present study revealed no changes in the serum levels of IL-8 in malaria patients compared with controls. Such result however, does not exclude a role for IL-8 in falciparum malaria, as it is produced by activated endothelial cells that may be captured by receptors on the endothelial surface. This would allow local concentrations of IL-8 to be generated at the vessel wall without being shed into the circulation. The marked elevation of ICAM-1 and VCAM-1 in serum of falciparum malaria patients may support the concept that dysfunction of the endothelium is important in the pathophysiology of the disease. Increased level of IL-6 in serum of patients may contribute to endothelial damage and dysfunction by expression of endothelial adhesion molecules that in turn result in infected erythrocytes attraction to the endothelium and pathologic endothelial dysfunction.
