Pathologic and immunopathologic studies were done in four patients with the hemolytic uremic syndrome. The principal lesions involved the endothelial and subendothelial regions of the renal arterioles and of the glomerular capillaries. The endothelial cells were swollen and, in the case of the glomerular capillary loops, separated from the basement membrane by an accumulation of material in the subendothelial space. In contrast to the glomerular capillaries, the endothelial changes in the renal arterioles were associated with a striking deposition of fibrinogen or its derivatives. No evidence for the operation of immune mechanisms of the type known to be associated with the development of vascular pathology was found to account for the microangiopathy.
