The effect of change of renal replacement therapy on plasma lipoprotein (a) [Lp(a)] concentration

There is a suspicion that atherogenesis is enhanced in PD patients vs. HD patients. Lipoprotein a (Lpa) is an atherogenic lipid, the levels of which are elevated in both PD and HD. Rather than a cross-sectional view of Lpa levels, in this paper the patients' Lpa levels were followed as a function of modality change.

In 21 patients on HD or CAPD who were transplanted, Lpa levels fell in 8 CAPD patients but remained similar in 13 HD patients. In 11 patients whose transplants failed and who went on either HD or CAPD, Lpa levels increased in those put on CAPD but not those who started HD. In 16 patients who were changed from CAPD to HD, Lpa levels fell significantly.

Comment: The data show that modality affects Lpa levels, being higher on CAPD than on HD or in transplant patients. The implication is that CAPD patients may run an increased atherogenic risk. (John T. Daugirdas, M.D., University of Illinois at Chicago)
