Background
Multiple organ dysfunction syndrome is not uncommon in critically ill children. While many of these children receive CRRT for management of AKI, there is no standard approach available for managing liver failure in which several metabolites that are highly protein bound accumulate, and thus are not cleared with conventional CRRT. Molecular Adsorbent Recycling System (MARS) has been successfully used in these situations, but is unavailable in most centers. Modification of CRRT with Single-Pass Albumin Dialysis (SPAD) has been reported previously.
Methods
We report our experience in four children who were treated with SPAD-CRRT. All patients received CRRT (CVVHDF) with a clearance of 2 L/hr/1.73m2. For SPAD, 400 mL of 25% albumin was added to the 5 L dialysate (PrismaSol®) bag to give final albumin concentration of 1.85%. Serum bilirubin was used as a surrogate marker of efficacy of SPAD. Serum and dialysate bilirubin concentrations were monitored to calculate the mass bilirubin removal.
Results
The findings are briefly summarized in the Table.
Conclusion
Our experience shows >10-fold increase in bilirubin clearance with SPAD-CRRT. While SPAD-CRRT is effective in decreasing serum bilirubin and other toxins, its impact on removal of nutrients and medications is currently unknown, Further studies are needed to see if SPAD-CRRT can improve patient outcomes.
Case | Age (yrs) | Sex | Diagnosis | Max. Bilirubin (mg/dL) | SPAD duration (hrs) | % reduction in bilirubin with SPAD | Outcome |
1 | 0.6 | M | Hemophagocytic histiolymphocytosis with liver failure. | 52 | 35 | 56% | Expired |
2 | 7 | M | Cystic fibrosis, sepsis, acute on chronic liver failure. | 33 | 96 | 42% | Recovered, expired 3 weeks later |
3 | 5 | M | Fulminant acute liver failure. | 24 | 26 | 21% | Received liver transplant |
4 | 3 | M | Neuroblastoma, post-HCT, VOD, and liver failure. | 32 | 240 | 73% | Recovered, expired 1.5 yrs later |
While severe hyperbilirubinemia was the main reason for using SPAD in patients 1, 2, and 4, it was used as a bridge to liver transplant in patient #3.
