Lipid and lipoprotein levels were measured in undialyzed uremic men and compared with levels of healthy control subjects. The patients had lower high-density lipoprotein (HDL) cholesterol (mean +/- SD, 46.3 +/- 14.8 vs 54.1 +/- 18.2 mg/dl) and increased serum triglycerides (197 +/- 151 vs 142 +/- 87.7 mg/dl). When compared with patients maintained on dialysis, the undialyzed patients had higher HDL cholesterol (46.3 +/- 14.8 vs 30.3 +/- 13.3 mg/dl), serum cholesterol (226 +/- 81 vs 151 +/- 42 mg/dl), and triglycerides (197 +/- 151 vs 146 +/- 105 mg/dl). ⋯ Within the undialyzed patient group, black patients had lower serum cholesterol and triglycerides and higher HDL and HDL3 cholesterol than white patients. Apoprotein A-I levels were higher and apoprotein B levels were lower in the black patients. There was a strong correlation (r = 0.9501) between apoprotein A-I and HDL levels in the black patients, but not in the white patients (r = -0.148).(ABSTRACT TRUNCATED AT 250 WORDS)
