title: Non-insulin-dependent diabetes and renal replacement therapy.
abstract: Reports of renal replacement therapy in diabetes usually refer to patients with insulin-dependent diabetes mellitus (IDDM) only, and little is known about renal failure in non-insulin-dependent diabetics (NIDDM). A high proportion, 46/141 (32%), of the diabetics treated at our unit since 1974 had NIDDM. They were older at treatment (56 +/- 9 years, mean +/- SD) compared to the IDDM patients (39 +/- 10 years, p less than 0.001), and had a shorter duration of diabetes (13 +/- 8 years versus 23 +/- 8 years, p less than 0.001). Asians and Afro-Caribbeans accounted for 48% of the NIDDM patients (22/46) compared to only 7% of those having IDDM (6/95, p less than 0.0001). Non-diabetic renal disease accounted for the renal failure in 32% (15/46) of the NIDDM patients but only in 10.5% (10/95) of the IDDMs (p less than 0.001). Despite these differences the prevalence of other diabetic complications (retinopathy, neuropathy, and cardiovascular disease) was similar. Patient survival after transplantation was poorer in NIDDM than IDDM (23% and 57%, respectively, at 2 years). Survival on dialysis was equally poor in NIDDM and IDDM. Thus, NIDDM patients treated for renal failure are more commonly non-European and more often have non-diabetic renal disease. Yet other diabetic complications occur to the same extent in both IDDM and NIDDM patients with diabetic nephropathy.
