The catabolic stress of labor, involutional changes of the uterus, and internal sequestration of blood are potential sources of metabolic decompensation of the affected mother. Fetal growth should be monitored to detect any signs of essential amino acid deficiency. Pregnancy management: For women with MSUD, metabolic control should be rigorously maintained before and throughout pregnancy by frequent monitoring of plasma amino acid concentrations and dietary adjustments to avoid the likely teratogenic effects of elevated maternal leucine plasma concentration.

Before confirmatory molecular testing is complete, at-risk neonates can be managed with an MSUD prescription diet if serial plasma amino acid profiles provide evidence of MSUD.

Early diagnosis may allow management of asymptomatic infants out of hospital by experienced providers. Surveillance: Weekly or twice-weekly assessment of amino acid profile for rapidly growing infants weekly amino acid profile assessment in children, adolescents, and adults routine monitoring of calcium, magnesium, zinc, folate, selenium, and omega-3 essential fatty acid levels at least monthly visit with a metabolic specialist in infancy assessment of developmental milestones at each visit or as needed.Įvaluation of relatives at risk: It can be determined if newborn sibs of an affected individual (who have not been tested prenatally) are affected (1) by plasma amino acid analysis at approximately 24 hours of life or (2) by molecular genetic testing of umbilical cord blood if the family-specific pathogenic variants have been identified. Prevention of secondary complications: Any trauma care or surgical procedures should be approached in consultation with a metabolic specialist.

Consider a trial of enteral thiamine to determine if an affected individual may have thiamine-responsive disease.

In those who have not undergone liver transplantation, strict and consistent metabolic control can decrease the risk of developing neuropsychiatric morbidities. Prevention of primary manifestations: Transplantation of allogeneic liver tissue affords affected individuals an unrestricted diet and protects them from metabolic crises, but does not reverse preexisting psychomotor disability or mental illness. Adolescents and adults with MSUD are at increased risk for attention-deficit/hyperactivity disorder, depression, and anxiety disorders and can be treated successfully with standard psychostimulant and antidepressant medications. Brain edema is a common complication of metabolic encephalopathy and requires careful management in an intensive care setting. Some centers use hemodialysis/hemofiltration to remove BCAAs from the extracellular compartment, but this intervention does not alone establish net protein accretion.

Acute metabolic decompensation is corrected by treating the precipitating stress while delivering sufficient calories, insulin, free amino acids, isoleucine, and valine to achieve sustained net protein synthesis in tissues.

Use of a 'sick-day' formula recipe (devoid of leucine and enriched with calories, isoleucine, valine, and BCAA-free amino acids) combined with rapid and frequent amino acid monitoring allows many catabolic illnesses to be managed in the outpatient setting. A BCAA-restricted diet fortified with prescription medical foods can maintain average plasma BCAA concentrations within standard reference intervals and preserves the ratios among them. Treatment of manifestations: Treatment consists of dietary leucine restriction, BCAA-free medical foods, judicious supplementation with isoleucine and valine, and frequent clinical and biochemical monitoring.
