[Histomorphologic analysis of kidney lesions in hemorrhagic fever with renal syndrome]

Data on morphology of the kidneys in hemorrhagic fever with the renal syndrome (HFRS) are discussed. In the kidneys of 10 decreased patients (with time period from the onset of the disease till death 4--13 days), in whom the disease proceeded with azotemia and oligo-anuria, there were observed oligemia of the glomeruli with secondary changes in the cellular elements, dystrophic changes in the tubules, these changes being particularly pronounced in the proximal segment, and being accompanied by nephrohydrosis; beginning with the 4--6th day signs of regeneration, edema in the walls of vessels and swelling of a hypoxic character were noted. A distinguishing feature of HFRS was a drastic plethora of the jextamedullar zone with hemorrhages due to venous congestion. The changes in the kidneys observed in HFRS were similar to morphological changes in acute renal insufficiency (ARI) of the type of "shock kidney". A characteristic feature of API in HFRS was a high degree of sequestration of the blood flow in the medullar layer.
