In recent years there has been a dramatic increase of almost epidemic
proportions in the incidence of patients with type II diabetes mellitu
s who reach end-stage renal failure and enter renal replacement progra
mmes. This is mainly due to the greater prevalence and better survival
of patients with type II diabetes and diabetic nephropathy. Against t
his background measures to prevent the appearance and progression of d
iabetic nephropathy are of immense interest. Apart from the undoubted
role of hyperglycaemia, the importance of genetic determinants of neph
ropathy has recently been recognized. Factors of proven or suspected e
fficacy in attenuating progression include: hypertension, hyperglycaem
ia, smoking and proteinuria. The role of dietary protein intake is les
s well documented. Nephropathy in type II diabetes has become the sing
le most common cause of end-stage renal failure in Germany and is toda
y a major challenge to clinical nephrology.
