[Cell mediated immunity in a mercury nephrotic syndrome (author's transl)].

A case of extramembranous glomerulonephritis seen in a patient in contact with mercury diodide is reported. The responsibility of mercury in this occurrence of this nephropathy is confirmed by positive tests exploring cell mediated immunity. The other possible actions of mercury are described: modifications in renal tubular antigen, or in a tissue or serum protein, with antibody production and secondary apparition of immune complexes which deposit in the glomerules.
