[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. In spite of therapy by steroids, a rapid worsening of renal functions accompanied a nephrotic syndrome. Supplementing hemodialysis helped patients to survive without recurrence of hemoptysis. Heparinotherapy prescribed on the creation of an arteriovenous fistula seemed to have brought a temporary improvement of the renal function.
