Intermediate have the maple syrup odor to their urine and may also present with developmental delay and feeding problems in infancy. Oftentimes they are diagnosed with MSUD between 5 months and 7 years old, presenting with intellectual disability. [thinkgenetic.com]

The clinical presentation is very similar to that of intermediate maple syrup urine disease, with the exception of early-onset lactic acidosis. [emedicine.medscape.com]

• Decerebrate Posturing

  Neurological signs will alternate from hypo- to hypertonia and extension of the arms resembling decerebrate posturing. At this time the characteristic burnt sugar or maple syrup odor to the urine is apparent. [themedicalbiochemistrypage.org]

A new metabolic workup was ordered, showing similar results. [pediatrics.aappublications.org]

Only samples with both increased total leucine and increased alloisoleucine would lead to further metabolic workup. This approach appears promising for further reducing false-positive rates. [clinchem.aaccjnls.org]

ACER-001 was granted orphan drug designation as a potential treatment for MSUD in 2014. [acertx.com]

TREATMENT When the condition is diagnosed and during episodes, treatment involves eating a protein-free diet and correction of the metabolic consequences of the elevated amino acid levels. [secure.ssa.gov]

Treatment: Treatment involves dietary restriction of the amino acids leucine, isoleucine, and valine. This treatment must begin very early to prevent brain damage. [medigoo.com]

Prognosis Prognosis is good for those who are diagnosed early, treated promptly and who follow a strict lifelong diet. The documents contained in this web site are presented for information purposes only. [orpha.net]

Diagnosis - Maple syrup urine disease Prognosis - Maple syrup urine disease This disease can be life threatening if untreated. Even with dietary treatment, stressful situations and illness can still cause high levels of certain amino acids. [checkorphan.org]

What is the prognosis? With treatment before any crises occur, lifetime adherence to the diet, and prompt treatment of illnesses, prognosis is good, and normal development and IQ are expected. [medicalhomeportal.org]
