Acute renal failure of leptospirosis: nonoliguric and hypokalemic forms.
Acute renal failure induced by leptospirosis was studied in 56 patients. A higher frequency of nonoliguric renal failure was observed with lower morbidity and mortality rates than in oliguric forms. In addition, 45% of the patients in this series were hypokalemic, and no hyperkalemic patients were seen. A prospective study in 11 patients showed an initially elevated urinary fractional potassium excretion that fell simultaneously with the high urinary fractional sodium excretion and the urinary K/Na ratio, suggesting an increased distal potassium secretion due to an increased distal sodium delivery consequent to functional impairment of the proximal reabsorption of sodium.
