BACKGROUND: 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. STUDY
DESIGN: Retrospective, matched cohort analysis. SETTINGS & PARTICIPANTS: 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. PREDICTOR: TIPS placement compared to serial LVP. OUTCOME: Change in
eGFR over 90 days' follow-up. MEASUREMENTS: Multivariable regression stratified
by baseline eGFR<60 versus ?60mL/min/1.73m(2); analysis of effect modification
between TIPS placement and baseline eGFR. RESULTS: 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. LIMITATIONS: Outcomes restricted by clinically recorded data;
clinically important differences may still exist between the TIPS and LVP cohorts
despite good statistical matching. CONCLUSIONS: 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.
