Abstract.
Objective: The authors assessed the efficiency, tolerance and outcome of neonates and children with maple syrup urine disease (MSUD) in acute decompensation managed by endogenous and extracorporeal removal of accumulated MSUD metabolites. Design: Single center cohort study. Setting: Pediatric and neonatal intensive care unit in a tertiary care hospital. Patients: Between January, 1991, and June, 1999, six neonates and six children in acute decompensation of MSUD were included in the study. Each of them had two of the three following criteria: comatose state, gastrointestinal intolerance, leucine plasma levels over 1700 µmol/l. Interventions: Patients were treated by combined nutrition manipulation and continuous venovenous extracorporeal removal therapies (CECRT) including hemofiltration, hemodialysis or hemodiafiltration. A clinical and biological evaluation was performed before, during and following the treatment. Results: Eleven out of the 12 patients survived. One child had two acute episodes at 6.5 and 9 years old. Eight patients recovered a normal cerebral performance category score. In all cases, plasma leucine level decreased according to a logarithmic mode within 11–24 h hemodiafiltration combined with nutritional support whereas, with nutrition alone after stopping CECRT, the decrease in leucine plasma levels was slower, following a linear mode. Eight patients were supplemented with valine and isoleucine for mean plasma values of 177±92 and 68±66, respectively. Conclusion: In severe acute decompensation of MSUD, CECRT combined with nutritional support limit central nervous system damage, by dramatically decreasing branched chain amino and keto acid levels.
