Decrease in lipoprotein(a) after renal transplantation is related to the glucocorticoid dose.
Serum lipoprotein(a) [Lp(a)] concentrations and apolipoprotein(a) phenotypes were determined in 46 patients with end-stage renal disease both before as well as 1 week and 1, 3 and 6 months after renal transplantation. Immunosuppressive therapy consisted of cyclosporin A, prednisone and azathioprine. Before transplantation median Lp(a) levels did not differ between the patients and a healthy control group. ⋯ As steroid doses were gradually tapered, Lp(a) concentrations subsequently increased, although at 6 months levels were still significantly reduced (P < 0.01) in women. No significant correlation was observed between Lp(a) and whole-blood cyclosporin levels, nor was there any correlation with the azathioprine dose. The reduction in Lp(a) concentrations was seen for all apo(a) phenotypes observed in the study.
