Immunomodulation, Acute Renal Failure, and Complications of Basiliximab Use After Liver Transplantation: Analysis of 114 Patients and Literature Review.

Basiliximab is considered to be effective in preventing cellular rejection (CR) in solid organ transplantation and is commonly used for renal transplants. The aim of this study was describe the population of patients undergoing orthotopic liver transplantation (LT) receiving basiliximab in the period 2012-2016 in the liver transplant service at the State University of Campinas, São Paulo, Brazil. We analyzed 114 patients who underwent LT and received basiliximab; 83 (72.8%) were male and 31 (27.2%) female, with an overall mean age of 54.3 years. Immunosuppression was performed with corticosteroids during anesthetic induction, and postoperatively with tacrolimus in 85.5%, sodium mycophenolate in 81.7%, cyclosporine in 12.7%, and everolimus in 15.5% of patients. CR was observed in 25.43% of patients, confirmed by biopsy in 15 patients: 50% acute CR, 21.42% late acute CR, and 28.57% chronic CR. Thus, the data are consistent with the literature regarding the benefit of using basiliximab as induction therapy while reducing the incidence of CR after LT, but on univariate analysis to evaluate factors associated with the occurrence of CR, the analyzed variables did not present statistical significance. There was acute renal failure (ARF) in 46.84% of patients and hemodialysis was performed in 20% of cases. In a previous series in our service, there was an ARF rate of 50%, so the incidence reduction of ARF after basiliximab use was 3.16%. Moreover, there was 6.95% hepatic artery thrombosis, 2.6% portal vein thrombosis, 2.6% biliary fistulas, 17.4% pneumonia, and 3.4% sepsis, which did not differ from the literature or from our earlier study without the use of basiliximab, suggesting the safety of this medication. In conclusion, in this series, basiliximab influenced the decrease of the CR incidence with no proven benefit on improvement in the ARF.
