A 15-Year Retrospective Study of Supportive Extracorporeal Therapies Including Plasma Exchange and Continuous Venovenous Hemodiafiltration of 114 Adults with Acute Liver Failure Awaiting Liver Transplantation

Abstract

Background Recently, there has been a recommendation to utilize a combination of supportive extracorporeal therapies, specifically plasma exchange and continuous venovenous hemodiafiltration, in patients with acute liver failure. This 15-year retrospective study aimed to evaluate supportive extracorporeal therapy, including plasma exchange and continuous venovenous hemodiafiltration, for 114 adults with acute liver failure awaiting liver transplant. Material/Methods In this retrospective study, the medical records of 1288 adult patients who underwent liver transplantation and 161 adult patients who received alternative therapy were analyzed; 114 patients who received combined supportive extracorporeal therapy for acute liver failure were included in the study. Biochemical laboratory data were compared before and after therapy. Results The study included 50 male and 64 female patients. The first group (34 patients) recovered with liver transplantation, and 4 patients died in the first year after liver transplantation. In the second group (80 patients), 66 patients recovered without liver transplantation, while 14 patients died within the first 2 weeks after therapy. All patients showed significant reductions in serum hepatic function tests (alanine transaminase, aspartate transaminase, and total bilirubin), ammonia, and prothrombin time/international normalized ratio after discontinuation of combined supportive extracorporeal therapy ( P <0.01). There was also a significant improvement in the hemodynamic parameter. Conclusions This combined extracorporeal therapy can be used as a supportive treatment for both recovery and bridge to liver transplantation in patients with acute liver failure. In addition, treatment can be continued until liver regeneration and until a usable donor is found.

“…[ 13 ] Additionally, there are studies comparing the use of TPE alone versus the combination of TPE with CRRT in adult patients. [ 14 ] Our aim is to investigate the efficacy of these treatments in children with acute liver failure and those with AOCLF, and to demonstrate the treatment outcomes of TPE alone versus the combination of TPE with continuous venovenous hemodiafiltration (CVVHDF).…”
