Observations in 5 patients dying with leptospirosis (at 6-30 days after the onset) caused by leptospira of the Hebdomadis serogroup are described. Bright jaundice developed due to severe serous liver centrilobular edema with pronounced dissociation of the liver cell bands, cholestasis, and cloudy swelling of hepatocytes. Albuminuria, oliguria, and uraemia were caused by acute tubular and interstitial nephritis. Hemorrhagic diathesis with small bleedings in the skin, mucous and serous membranes was associated with the impairment of permeability of microcirculatory vessels. Focal necroses of skeletal muscles, myocardiodystrophy, and focal myocarditis, serous leptomeningitis were also seen. Few leptospirae could be detected extracellularly (often attached to the outer host cell membranes) by Warthin-Starry's method of silver impregnation of paraffin sections and by indirect immunofluorescence, much more rarely could they be demonstrated by Levaditi's method of silver impregnation of pieces of the viscera. Most leptospirae were present in the liver in the case of death on the 6th day when no antibodies were yet present in the blood. Since the 9th day when the antibodies did appear, leptospirae gradually disappeared from the liver and were found in the kidneys. It is suggested that some leptospiral cytotoxic products play a role in the pathogenesis of leptospirosis.

Chronic Renal Failure is a generalized functional impairment, due to Kidneys inability to maintain volume and composition of body fluids and solutes within normal conditions. In the attempt to point out the pathophysiology of Bright's syndrome, the Authors review the "intact nephron hypothesis" and his functional reserve. The uraemic clinical appearance is a very wide field of investigations and beside their own experience, the Authors present some datas and theories to explain the coming out and the evolution of poliuria and oliguria, hypertension, heart pathology, anemia and bleedings, hormonal and metabolic pathways alterations, calcium and bone diseases and central and peripheral uraemic neuropathy.
