Changes in Kidney Function After Transjugular Intrahepatic Portosystemic Shunts Versus Large-Volume Paracentesis in Cirrhosis: A Matched Cohort Analysis.

ABSTRACT: Patients with cirrhosis and refractory ascites have physiologic and hormonal dysregulation that contributes to decreased kidney function. Placement of a transjugular intrahepatic portosystemic shunt (TIPS) can reverse these changes and potentially improve kidney function. We sought to evaluate change in estimated glomerular filtration rate (eGFR) following TIPS placement.Retrospective, matched cohort analysis.Patients who underwent first-time TIPS placement for refractory ascites in 1995 to 2014. Frequency matching was used to generate a comparator group of patients with cirrhosis and ascites treated with serial large-volume paracentesis (LVP) in a 1:1 fashion.TIPS placement compared to serial LVP.Change in eGFR over 90 days' follow-up.Multivariable regression stratified by baseline eGFR<60 versus ?60mL/min/1.73m(2); analysis of effect modification between TIPS placement and baseline eGFR.276 participants (TIPS, n=138; serial LVP, n=138) were analyzed. After 90 days, eGFRs increased significantly after TIPS placement in participants with baseline eGFRs<60mL/min/1.73m(2) compared to treatment with serial LVP (21 [95% CI, 13-29] mL/min/1.73m(2); P<0.001) and was no different in those with eGFRs?60mL/min/1.73m(2) (1 [95% CI, -9 to 12] mL/min/1.73m(2); P=0.8). There was significant effect modification between TIPS status and baseline eGFR (P=0.001) in a model that included all participants.Outcomes restricted by clinically recorded data; clinically important differences may still exist between the TIPS and LVP cohorts despite good statistical matching.TIPS placement was associated with significant improvement in kidney function. This was most prominent in participants with baseline eGFRs<60mL/min/1.73m(2). Prospective studies of TIPS use in populations with eGFRs<60mL/min/1.73m(2) are needed to evaluate these findings.

Project description:BackgroundTreatment of refractory ascites in liver cirrhosis is challenging. Transjugular intrahepatic portosystemic shunt and alfapump® have been proposed for the management, but few data comparing both exist.AimsThe aim of this study was to evaluate the characteristics and outcomes of patients treated with transjugular intrahepatic portosystemic shunt and alfapump® for refractory ascites at our centre.MethodsAll consecutive patients were retrospectively reviewed for baseline characteristics, efficacy of treatment, complications and survival.ResultsIn total, 19 patients with transjugular intrahepatic portosystemic shunt and 40 patients with alfapump® were included. Patients with transjugular intrahepatic portosystemic shunt had better liver function and less hepatic encephalopathy at baseline. Fifty-eight per cent of patients developed hepatic encephalopathy in the first six months after transjugular intrahepatic portosystemic shunt. In patients with alfapump®, renal function decreased and 58% developed prerenal impairment and 43% hepatorenal syndrome in the first six months. Alfapump® patients with new catheters required less reinterventions (26% versus 57% with old catheters, p = 0.049). Transplant-free survival at 1 year was 25% in alfapump® and 65% in transjugular intrahepatic portosystemic shunt. Hepatic encephalopathy predicted transplant-free survival in patients with alfapump® (hazard ratio 2.00, 95% confidence interval 0.99-4.02, p = 0.05). In a sensitivity analysis comparing patients with similar liver function, the rate of hepatorenal syndrome and prerenal impairment was higher in patients with alfapump® and these patients were hospitalised more frequently, whereas the rate of hepatic encephalopathy was similar in both treatment groups.ConclusionsBoth transjugular intrahepatic portosystemic shunt and alfapump® were effective treatments for refractory ascites in cirrhosis. Patients treated with transjugular intrahepatic portosystemic shunt had a better one-year transplant-free survival but had less negative prognostic factors at baseline. Selecting patients without hepatic encephalopathy prior to implantation of an alfapump® might improve transplant-free survival.
