title: Protein restriction, blood pressure and the progression of diabetic nephropathy.
abstract: Diabetic nephropathy is the long-term complication of diabetes responsible for the greatest increased mortality. Clinical nephropathy is characterised by a triad consisting of persistent proteinuria (total urinary protein greater than 0.5 g/24 h), rising arterial pressure and declining renal function. The role of treatment of raised blood pressure and the influence of dietary protein restriction on the established progressive phase of the disease are discussed. Subclinical elevations of urinary albumin excretion rates (greater than 30 micrograms/min; microalbuminuria), glomerular hyperfiltration and marginal elevations of arterial pressure are early markers of later clinical nephropathy which appear to respond to strict blood glucose control, blood pressure treatment and lowered dietary protein intake. Recent evidence to suggest that an inherited predisposition to raised arterial pressure may confer the susceptibility to diabetic nephropathy is presented.
