title: Lipoprotein(a) levels in chronic renal disease states, dialysis and transplantation.
abstract: Lipoprotein(a) is an independent risk factor for cardiovascular disease. Lipoprotein(a) levels were measured in 196 patients (103 Male [M]: 93 Female [F]) with chronic renal diseases and in 116 controls. Median levels of Lipoprotein(a) [Lp(a)] were found to be significantly elevated in patients with untreated chronic renal disease (285,285 mg/L; M,F; range 30-1675 mg/L) and in those treated with continuous ambulatory peritoneal dialysis (320, 603; M,F; range 50-1450) compared with controls (70,51; M,F; range 1-750; p less than 0.01 Males, p less than 0.001 Females). Lp(a) levels in patients treated by haemodialysis (133,35; M,F; range 5-685) and renal transplantation (100,95; M,F; range 10-1700) were not significantly different from controls. Lipoprotein(a) levels correlated inversely with serum albumin in the combined dialysis group (r = -0.34, p less than 0.001), and with urinary protein loss in the combined transplant and chronic renal diseases groups (r = 0.29, p less than 0.01). This correlation of Lp(a) with protein metabolism suggests a similarity with changes in other apolipoprotein-B containing lipoproteins in nephrosis. These findings may be relevant to the increased risk of atherosclerosis in patients with chronic renal disease and to their optimum mode of renal replacement therapy.
