Introduction:
The aim of our study was a 30-day follow-up of the use of early detection of endotoxin by the endotoxin activity assay (EAA) for patients with acute liver failure superimposed on chronic liver disease (AoCLF) and treated with polymyxin-B hemoperfusion-based (PMX-DHP) treatment and albumin dialysis in the molecular adsorbent recirculating system (MARS).
Materials And Methods:
From February 2008 to July 2010, we evaluated 10 AoCLF patients experiencing systemic inflammatory response syndrome (SIRS) in association with suspected infection and an EAA-positive test (>0.60). These patients awaiting liver transplantation (OLT) showed similar Model End-Stage Liver Disease (MELD) scores (range, 19-25) and encephalopathy grade ≤ 2. Five patients received therapy to remove endotoxins with PMX-DHP with MARS treatment for liver failure (group A); the other 5 patients received MARS treatment only (group B).
Results:
Two PMX-DHP treatments were performed in 4 group A patients (average EA=0.66 [range, 0.61-0.70]) and 3 treatments for 1 patient (EA=0.92). All 5 subjects underwent an average of 4 MARS treatments (range, 3-5). At the end of therapy, the median EA level was 0.42 (range, 0.37-0.48). As reported in the literature, we achieved a significant improvement in liver and kidney functions using MARS. Measurements of lactate, interleukin (IL)-6, and tumor necrosis factor (TNF)-α were significantly improved among patients treated with the extracorporeal therapies. At 30 days of observation, all 5 patients treated with MARS plus PMX-DHP are alive. In group B, a mean of 7.5 MRAS treatments were performed. We observed an improvement in hemodynamic and liver functions with reduced levels of proinflammatory cytokines and lactates in 4 patients. One patient showed no improvement in clinical status with the development of sepsis and subsequent multiorgan failure after 24 days.
Conclusion:
The possibility of an early diagnosis using the EAA in AoCLF patients could prevent the progression of the sepsis cascade. The use of PMX-DHP and MARS in these patients, could lead to resolution of clinical status in a short time.
Insights
Early endotoxin detection using EAA in acute liver failure patients treated with polymyxin-B hemoperfusion (PMX-DHP) and MARS dialysis improved outcomes. All patients receiving PMX-DHP and MARS survived 30 days, showing reduced inflammatory markers.
Area of Science:
- Hepatology
- Critical Care Medicine
- Immunology
Background:
- Acute liver failure superimposed on chronic liver disease (AoCLF) presents significant challenges.
- Systemic inflammatory response syndrome (SIRS) and suspected infection are common complications.
- Early endotoxin detection is crucial for timely intervention.
Purpose of the Study:
- To evaluate the 30-day outcomes of early endotoxin detection using the endotoxin activity assay (EAA).
- To assess the efficacy of polymyxin-B hemoperfusion (PMX-DHP) combined with albumin dialysis (MARS) in AoCLF patients.
- To investigate the impact of combined therapy on inflammatory markers and clinical status.
Main Methods:
- 10 AoCLF patients with SIRS and positive EAA (>0.60) were studied.
- Patients were divided into two groups: Group A (PMX-DHP + MARS) and Group B (MARS only).
- EAA, MELD scores, and encephalopathy grades were assessed; inflammatory markers (lactate, IL-6, TNF-α) were monitored.
Main Results:
- The combined PMX-DHP and MARS therapy (Group A) resulted in a median EAA reduction to 0.42.
- Significant improvements in liver and kidney function, lactate, IL-6, and TNF-α were observed in Group A.
- All 5 patients in Group A survived the 30-day follow-up, while one patient in Group B developed sepsis and multiorgan failure.
Conclusions:
- Early EAA diagnosis in AoCLF patients can help prevent sepsis progression.
- Combined PMX-DHP and MARS treatment shows promise for rapid clinical improvement in AoCLF patients.
- Extracorporeal therapies effectively reduce endotoxin levels and inflammatory cytokines.
