Abstract

Acute renal failure (ARF) after liver transplantation is associated with high mortality and morbidity. Early therapeutic or preventive intervention is hampered by the lack of early effective prognostic factors. Recent studies indicated that serum levels of cystatin C and beta2-microglobulin (beta2 MG) as well as urinary beta2 MG and N-acetyl-beta-D-glucosaminidase (NAG) would increase in patients with early and mild renal impairment. In this study, these factors were detected during the different stages in patients who accepted orthotopic liver transplantation (OLT), and their feasibilities to predict early ARF after OLT were also analyzed. Sixty patients with normal blood urea nitrogen (BUN) and serum creatinine (SCr) who received modified piggyback liver transplantation without veno-venous bypass were prospectively studied. Blood samples were drawn from patients for the determination of serum beta2 MG (n = 60), SCr (n = 60) and serum Cystatin C (n = 39) at following 5 intervals: before operation (T0), 20 minutes before anhepatic phase (T1), 25 minutes in anhepatic (T2), 60 minutes after reperfusion (T3) and at the end of operation (T4). Urinary beta2 MG (n = 60) and NAG (n = 60) were also examined at following 3 intervals: be...Continue Reading
