Abstract:
Acute decompensation of maple syrup urine disease (MSUD) is usually treated by enteral feeding with an amino‐acid mixture without leucine (Leu), valine or isoleucine. However, its administration is ineffective in cases of gastric intolerance and some adult patients refuse enteral feeding via a nasogastric tube. We developed a new parenteral amino‐acid mixture for patients with MSUD. Methods Seventeen decompensation episodes in four adult patients with MSUD treated with a parenteral amino‐acid mixture (group P) were compared to 18 previous episodes in the same patients treated by enteral feeding (group E). Results The mean Leu concentration at presentation was similar in the groups P and E (1196.9 μmol/L and 1212.2 μmol/L, respectively). The mean decrease in the Leu concentration during the first 3 days of hospitalisation was significantly higher in group P than group E ( p = 0.0026); there were no side effects. The mean duration of hospitalisation was similar (4 vs. 4.5 days, p = NS). No patient in group P deteriorated whereas one patient in group E required dialysis. Conclusion This new parenteral amino‐acid mixture is safe and allows efficient Leu concentration decrease during acute MSUD decompensation episodes in adults. Its use avoids the need for nasogastric tube insertion.
