β¦ Synopsis
Three patients with maple syrup urine disease were treated during the acute neonatal stage. Multiple exchange transfusions proved to be a satisfactory means of achieving rapid clinical and biochemical improvement during this phase. On the other hand, evidence is provided suggesting that in addition to exchange transfusions, a high calorie intake above 150 Cal/kg body weight/day is necessary to lower the plasma concentration of the branched chain amino acids to near-normal levels. As long as this calorie intake was not provided, further exchange transfusions failed to lower the plasma leucine concentration to below 17 mg/100 ml in one patient. It is assumed that this high calorie intake is necessary to prevent the breakdown of endogenous protein. Treatment of acute episodes in maple syrup urine disease should therefore not only eliminate the elevated alpha-keto acids and branched chain amino acids quickly (i.e. by multiple exchange transfusions or peritoneal dialysis), but in addition should provide a high calorie intake.

Two neonates with maple syrup urine disease were treated by exchange transfusion. Within 15 h blood leucine and K/CA concentrations were lowered from 2.6raM to 1.1raM using 570 to 620ml blood per kg body weight. The other branched-chain amino acid/keto acid pairs fell to normal. During exchange tran
Selenium (Se) status was studied in a patient with classical maple syrup urine disease (MSUD) receiving Se supplement. The basal plasma Se concentration was 0.06 pmol/l increasing to 2.1 pmol/1 after 40 days of supplementation. When the plasma Se distribution was analysed by gel filtration, a major
