[Evaluation of various renal function indices in a group of workers in the shoe industry]

The possible chronic nephrotoxicity of solvents has been investigated in a group of workers in the footwear industry. A number of indices of renal function were assessed in all subjects and a qualitative study of proteinuria carried out. The noted reduction in VFG would appear to be proportional to exposure doses. The other parameters, particularly the electrolytic balance, do not lend themselves to pathogenetic interpretations. The existence of a chronic nephrotoxicity of solvents cannot, however, be excluded.
