Renal dysfunction frequently occurs during the periods preceding and following
orthotopic liver transplantation (OLT), and in many cases, renal replacement
therapy (RRT) is required. Information regarding the duration of RRT and the rate
of kidney function recovery after OLT is crucial for transplant program
management. We evaluated a sample of 155 stable patients undergoing
post-intensive care hemodialysis (HD) from a patient population of 908 adults who
underwent OLT. We investigated the average time to renal function recovery
(duration of RRT required) and determined the risk factors for remaining on
dialysis > 90 days after OLT. Log-rank tests were used for univariate analysis,
and Cox proportional hazards models were used to identify factors associated with
the risk of remaining on HD. The results of our analysis showed that of the 155
patients, 28% had pre-OLT diabetes mellitus, 21% had pre-OLT hypertension, and
40% had viral hepatitis. Among the patients, the median MELD (Model for End-Stage
Liver Disease) score was 27 (interquartile range [IQR] 22-35). When they were
listed for liver transplantation, 32% of the patients had serum creatinine (Scr)
levels > 1.5 mg/dL or were on HD, and 50% had serum creatinine (Scr) levels > 1.5
mg/dL or were on HD at the time of OLT. Of the transplanted patients, 25%
underwent pre-OLT intermittent HD, and 14% and 41% underwent continuous renal
replacement therapy (CRRT) pre-OLT and post-OLT, respectively. At 90 days
post-OLT, 118 (76%) patients had been taken off dialysis, and 16 (10%) patients
had died while undergoing HD. The median recovery time of these post-OLT patients
was 33 (IQR 27-39) days. In the multivariate analysis, fulminant hepatic failure
as the cause of liver disease (p<0.001), the absence of pre-OLT hypertension (p =
0.016), a lower intraoperative fresh-frozen plasma (FFP) transfusion volume (p =
0.019) and not undergoing pre-OLT intermittent HD (p = 0.032) were associated
with performing RRT for less than 90 days. Therefore, a high proportion of OLT
patients showed improved renal function after OLT, and those who were diagnosed
with fulminant hepatic failure, had no pre-OLT hypertension, received a lower
transfused volume of intraoperative FFP and did not undergo pre-OLT intermittent
HD had a higher probability of recovery.
