High-dose ulinastatin to prevent late-onset acute renal failure after orthotopic liver transplantation.
RENAL FAILURE(2020)
Abstract
Purpose: To compare the efficacy and safety of two distinct doses of ulinastatin on late-onset acute renal failure (LARF) following orthotopic liver transplantation (OLT). Methods: The high-risk recipients that underwent OLT were divided into two groups according to ulinastatin dose: low-dose (LD) ulinastatin group, 0.8 million U/d; high-dose (HD) ulinastatin group, 1.6 million U/d. The primary outcome was the incidence of LARF, which was defined the newly onset acute kidney injury (AKI) stage III (KDIGO, 2012) within 7-28 post-transplant days. The second outcomes were early multiple organ retrieval assessments, length of hospital stay and safety events. Results: A total of 174 recipients were included (LD ulinastatin group, n = 55; HD ulinastatin group, n = 119). There was no significant difference in the incidence of LARF between LD (8/55, 14.50%) and HD (9/119, 7.56%) ulinastatin groups (HD vs. LD, HR, 0.49; 95%CI, 0.17-1.37; p = .1295). Multivariate Cox proportion risk regression model revealed HD ulinastatin (HR, 0.57; 95%CI, 0.38-0.98; p = .0464) was an independent protective factor for LARF. Early lactate level, oxygenation, AKI stage, graft function, and sequential organ failure assessment [SOFA] score were significantly improved in HD ulinastatin group versus LD ulinastatin group. No significant adverse events were observed in either group. Conclusions: Higher dose of ulinastatin (1.6 million U/d) might be preferable to prevent LARF after OLT, and it may contribute to the enhancement of early multiple organ recovery and thus attenuate the incidence of LARF.
