Effects of Immunosuppressive Drugs on Serum Fatty Acids of Phospholipids Fraction in Renal Transplant Recipients

Abstract Background Immunosuppressive medications often cause posttransplant hyperlipidemia. The effects of cyclosporine (CsA) and tacrolimus (Tac) on lipid profile is well-known; however, there are very few studies related to the effect of these immunosuppressants on fatty acids (FA) of phosholipids fraction (PL) in renal transplant recipients (RTR). We sought to analyze the FA profile in PL fraction of RTR treated with Tac or CsA. Methods The study included 65 renal transplant patients on CsA (n = 24, group I) or Tac (n = 41, group II), and 14 healthy controls. Individual serum FA concentrations were measured by gas chromatography. Chemstation software was used to analyze the data. Results No differences between studied groups and controls were noted for monounsaturated FA, polyunsaturated n-3 FA (PUFA n-3), PUFA n-6, or the ratio of PUFA n-6 to PUFA n-3. The following mean values of FA were significantly higher in the CsA-RTR and Tac-RTR as compared with controls: total FA ( P < .01 in both cases), saturated FA (SFA; P < .02 in both cases), C12 ( P < .003 in both cases), C18 ( P < .003 in both cases), and C18:2 ( P < .01 for CsA RTR; P < .02 for Tac RTR). No differences between the measurements in patients on CsA and in patients on Tac were noticed. Significant correlation between SFA and eGFR was observed only in the CsA RTR group ( P
