Family history of end-stage renal disease among incident dialysis patients.
As part of a larger study of genetic risk factors for the occurrence of renal failure, the prevalence of a family history of end-stage renal disease (ESRD) in first- and second-degree relatives of all incident dialysis patients treated in Georgia, North Carolina, and South Carolina (ESRD Network 6) in 1994 was ascertained. Family histories were obtained from 4365 dialysis patients (83% of those eligible), and 856 (20%) reported having a family history of ESRD. Among race-sex groups, 14.1% of Caucasian men, 14.6% of Caucasian women, 22.9% of African-American men, and 23.9% of African-American women reported a first- or second-degree relative with ESRD (P = 0.001). The prevalence of relatives with ESRD varied by the reported etiology: 22.2% in diabetes mellitus; 18.9% in hypertension, 22.7% in glomerulonephritis; and 13.0% of other etiologies (P = 0.001). Patient characteristics independently associated with family history of ESRD included race, younger age, higher levels of education, and etiology of ESRD. In this report, it is concluded that a large proportion of incident ESRD cases have close relatives with ESRD in whom preventive actions might be directed. Genetic analyses in multiply affected families may identify the inherited factors contributing to progressive renal failure.
