[Clinico-morphologic characteristics of leptospirosis with hemorrhagic syndrome].

Infectious toxic shock, acute renal and acute hepatorenal insufficiency are the principal morphoclinical syndromes in malignant forms of icterohemorrhagic leptospirosis. The major complications of acute renal and hepatorenal failure are pyoseptic involvements of the lungs, heart, and pancreas. Direct or indirect signs of the DIC syndrome and intravascular platelet aggregation are characteristic of all the principal clinical syndromes of malignant forms of leptospirosis.
