N/A


N/A


1 yr (1.4 mg/dL vs 1.5 mg/dL)


2% vs 0% (at 12 mo)

N/A


1 yr survival for pts with ≥ 3 mo RRT: (70.8% LTA vs 84.5% SLKT)

Even after matched-control analysis, there was no benefit in SLKT cohort vs LTA cohort outside of aforementioned RRT

Cumulative 5 yr SLKT survival of both organs (60.9%)


Cumulative 5 yr survival 42.6%

It is concluded that there is no definitive evidence of better graft/patient survival in SKLT vs LTA

5 yr SLKT survival (liver: 73.7% and kidney: 70%)


73.7% SLKT patient survival at 5 yr

5 yr survival (62.9% LTA vs 67.4% SLKT, P < 0.001)


0% with severe renal dysfunction


N/A


Liver graft survival and patient survival was better in SLKT vs LTA group


Martin et al[88] 2012

2327


15% decreased risk of graft loss with SLKT vs LTA (P = 0.02)


N/A


N/A


N/A


SLKT had higher graft survival rates than both KALT and LAKT


Sharma et al[86]


2112 (received RRT within 90 d before LT)


N/A


N/A


78% LTA survival at 6 mo (not associated with RRT duration)

N/A


Acute rejection episodes involving the liver were less in SLKT vs LTA
