[The effect of hemodialysis on endothelin-1 plasma levels in children with terminal renal insufficiency].
We analysed the effect of hemodialysis (HD) on endothelin (ET) plasma level in children with terminal renal failure. Twenty-five patients (pts) and 27 healthy children as controls were included in the study. There was no difference in ET plasma levels in pts before HD (1.97 +/- 1.45) and controls (2.08 +/- 1.47), but ET increased in plasma of pts after HD (4.10 +/- 3.66). To estimate the relationship of volume depletion or depuration on ET plasma level changes in pts during HD, ET was measured at three time points of HD (before ultrafiltration-UF, after UF, and after HD without fluid removal) in 10 pts. ET level was not significantly changed after UF (1.93 +/- 2.25 vs 1.71 +/- 1.50; ns), but was significantly increased after depuration (4.46 +/- 3.56; p < 0.05). There was no correlation between ET and blood pressure in controls and pts in either period of testing, neither with plasma renin activity, left ventricular mass index, and body weight changes during HD.
