To explore the possibility that hereditary factors increase the risk for end-stage renal disease (ESRD), 669 patients with ESRD in the province of Newfoundland, Canada from 1987 to 1993 were studied.
Detailed family histories were obtained from 584 (87%) consecutive probands and 499 spousal control subjects.
Diseases with a Mendelian pattern of inheritance accounted for 8.4% of the cases ; 4.5% of the cases were caused by autosomal dominant polycystic kidney disease (ADPKD).
Glomerulonephritis was the original cause of renal failure in 25% of the probands, diabetes mellitus (DM) in 20%, unknown in 14%, interstitial kidney disease in 11%, other disease in 12%, multifactorial in 4%, and hypertension in 5%. In the group without a Mendelian pattern of inheritance, 28% of the probands had a first-second-or third-degree relative with renal failure associated with death or dialysis versus 15% of the controls.
Compared with 0.4% of the control group, 1.2% of the first-degree relatives of probands developed renal failure (odds ratio [OR]=3.0 ; 95% confidence interval [Cl], 1.7 to 5.2).
No difference was observed when risks were compared for second-degree relatives, but a highly significant increased risk was observed for third-degree relatives (OR=2.1 ; 95% Cl, 1.2 to 3.4).
The highest rates of affected first-degree relatives occurred in probands with hypertensive renal failure (2.3%), DM (1.6%), and interstitial kidney disease (1.6%). (...)
