[Acute renal failure in the course of occupational lead intoxication. Chelation therapy responsability (author's transl)].

In a patient with occupational plumbism and a normal kidney function, EDTA therapy (1 g/24 h) resulted in a massive lead excretion (15 000 microgram/24 h) together with acute renal failure. A direct nephrotoxic effect of EDTA was excluded: after renal function returned to normal, EDTA could be subsequently readministered at progressively increasing doses (250 mg to 1 g/24 h) without any renal dysfunction. These findings strongly suggest a close relationship between the burden of lead mobilized by EDTA and the acute renal failure.

[Goodpasture's syndrome. A new case].

The authors report a new observation of Goodpasture's syndrome in a 21 years old patient. Diagnosis was made by renal biopsy after discovering, by immunofluorescence techniques, linear deposits of IgG and C3 on the renal basal lamina. Anti-basal lamina antibodies of the plasma were not found.
