Abstract:
Objective To study long-term post-liver-transplantation hyperuricemia (HUA) and the influence of urate-lowering therapyon renal functions of adult patients.Methods Among 428 cases undergoing liver transplantations during March 2011 to December 2013,206 patients,whose followup periods were above 1 year,were selected as the objects of study.Those whose two-time serum uric acid (SUA) levels tested not in the same day one year after operation ＞420 μmol/L (male),or female ＞360 μmol/L (female) were divided into HUA group,and non-HUA group.The serum creatinine (SCr) concentrations and glomerular filtration rate (eGFR) were analyzedin the two groups at their peak SUA to find whether there was any difference between the two groups.Meanwhile,27 HUA patients with abnormal renal function were given urate-lowering therapy and the differences in SCr and eGFR after the therapy were observed.Results 49.5％ patients sufferedlong-term HUA after liver transplantations.As compared with non-HUA group,SCrconcentrations were increased statistically (P＜0.05),and eGFR was reduced statistically in HUA group (P＜0.05).After 8-week uratelowering therapy among 27 patients,SUA level in 24 cases (88.9％,24/27) returned to the normal standard and SCr concentrations in 21 cases (77.8％,21/27) decreased for a certain degree.SUA levels were decreased to (349.93 ± 22.85)μmol/L from (532.94 ± 93.91) μmol/L (P＜0.001).SCr concentrations were decreased to (129.52 ± 19.06)μmol/L from (144.95 ± 13.51) μmol/L (P =0.016).The eGFR increased to (56.30 ± 11.46) ml · min-1 · 1.73 m-2 from (46.46 ± 8.11) ml·min-1 ·1.73 m-2(P =0.012),which showed a certain degree of improvement in their renal functions.Conclusion HUA is a long-term common complication in liver transplanted adult patients,which has a negative influence on patients' renal functions,so we need to pay enough attention to this.Urate-lowing therapy has a positive influence on the improvement of renal function if other factors were excluded from the treatment.
