[Renal involvement in convalescents after icterohemorrhagic leptospirosis]

Icterohemorrhagic spirochetosis convalescents develop slowly regressing renal dysfunctions most frequent of which are chronic renal failure, pyelonephritis and tubulointersticial nephritis, arterial hypertension. Renal disorders may be due to immunopathological reactions followed by activation of bacterial microflora. Damage from commissures at the sites of prior hemorrhage is also possible. In bovine leptospirosis renal damage is not so severe but it tends to progression. So, renal affection in leptospirosis is a specific pathology observed in any clinical form of the disease and demands surveillance in the regions of local focuses.
