Abstract

Background: Continuous hemodiafiltration is potentially more efficient than hemofiltration for removing low molecular metabolites.

Case report: A newborn (2100 g) was admitted suffering from acute distress with statuts epilepticus, liver failure with generalized hyperaminoacidemia, hypoglycemia and oligo-anuria. Peritoneal dialysis, performed on the 17th day of life, was ineffective and the patient was treated by continuous hemofiltration alternating with hemodiafiltration. Clearance of amino-acids was studied for 15 minutes under each technique. The amino-acid concentrations were measured in the infused fluid and in the ultrafiltrate. The baby died on the 20th day despite this treatment.

Results: Amino acid clearance by hemodiafiltration was 181 +/- 176% greater than by hemofiltration. The mean improvement for all amino acids was 148%, with extremes of +43% for citrulline and 941% for glutamic acid.

Conclusion: Continuous hemodiafiltration is an efficient method of removing amino acids; it could be used to treat severe inborn errors of metabolism such as leucinosis.
