[Platelet aggregation and the fibronectin level of the blood in children with chronic glomerulonephritis].

We compared platelet aggregation with changes in fibronectin (FN) plasma levels in children with various forms of primary CGN. We found that a rise in platelet aggregation and plasma FN level depends on CGN clinical form, extent of inflammation and sclerotic changes in nephric tissue. The greatest changes occurred in patients with nephrotic CGN and with segmentary glomerulosclerosis.
