Lipid metabolism and oxidative stress in children after liver transplantation treated with sirolimus

Pediatr Transplant. 2012 Dec;16(8):901-6. doi: 10.1111/petr.12007.

Abstract

Lipid disturbances are one of the most frequent side effects of SRL; however, clinical consequences are not known. The aim of the study was to evaluate the risk of AS in children after LTx treated with SRL. In 17 children with median age 13.2 yr (1.9-17.9) who received SRL on average for 4.1 yr (s.d. ± 2.9) we measured and compared with age-matched healthy control group (n = 45) lipid parameters and markers of AS: ADMA, oxyLDL, GSH, GPx, TC, TG, HDL cholesterol, LDL cholesterol, VLDL cholesterol, ApoAI, ApoB, ApoE, lipoprotein (a) (Lp(a)). We found no major differences in cholesterol, cholesterol in lipoprotein fractions and TG concentrations between patients receiving SRL and the control group. ApoE was markedly increased in the study group (19.1 g/L [±1.8]) when compared to controls (9.8 [±3.9]). ApoA1 was decreased in the study group: 1.30 g/L (±0.2) vs. 1.45 (±0.25), p = 0.04. ApoB and Lpa concentrations were similar in both groups. There were differences in oxidative stress markers: GSH 743 (±66.2) mol/mL vs. 780 (±48.2), p = 0.02 and GPx 32.8 (±5.5) U/gHb vs. 34.3(±2.6), p = 0.01. Markers of AS: ADMA did not differ between groups and oxidized LDLc was significantly lower in SRL group: 190 mU/mL (±113) vs. 237 (±107) in control, p < 0.05. SRL does not significantly disturb lipid metabolism and oxidative status in children after LTx.
