[Microalbuminuria--a risk indicator for the development of nephropathy in insulin-dependent diabetics].

The authors submit preliminary results of a prospective study in 65 insulin-dependent diabetics with a varying duration of the disease where they followed up the development of microangiopathic organ changes in relation to the compensation of diabetes and the development of clinically manifest proteinuria or albumin excretion (microalbuminuria). From the results ensues that in recent and postrecent patients the increased albumin excretion is as a rule only a manifestation of metabolically conditioned and treatable changes of renal function and is of minor importance for the prediction of the risk of development of diabetic nephropathy. In patients with prolonged duration of diabetes the position is not unequivocal and if the albumin excretion persists or increases despite intensive insulin treatment it is most probably an indicator of a high risk of development of diabetic nephropathy.
