Increased risk of attention deficit/hyperactivity disorder (ADHD), anxiety, and depression. If they stray from the diet, they can experience muscle spasms, breathing failure, intellectual and developmental disabilities or even coma. Complications of maple syrup urine disease include: Brain damage, neurological problems, and developmental delays. They can eat some low-calorie foods but must be very careful. People with MSUD get most of their nutrients from a prescribed liquid formula. Infections, stress, surgeries and injuries can lead to neurological damage at any age. The disease can lead to a buildup of toxic substances that cause organ and brain damage.Īdolescents and adults with MSUD are also at risk for attention deficit disorder, anxiety and depression. Eugenia and Justino Hurtado have four.Īll four of the Hurtado children were born with Maple Syrup Urine Disease (MSUD) - a rare genetic metabolic disorder in which the body is unable to break down certain parts of proteins due to an enzyme deficiency. Having one child in need of a liver transplant can be tremendously challenging for a parent.
They hope researchers will use this information to help other families like theirs. doi:10.2147/TACG.The Hurtados enrolled their children in the Studies in Pediatric Liver Transplant (SPLIT) database which follows children who receive a liver transplant in the U.S. (2017) The application of clinical genetics. Maple syrup urine disease: mechanisms and management. Blackburn PR, Gass JM, Vairo FPE, Farnham KM, Atwal HK, Macklin S, Klee EW, Atwal PS. Neuroimaging Findings of Organic Acidemias and Aminoacidopathies. GARD recognizes coping with a rare disease. Navigating unexpected challenges, coordinating care, and handling financial concerns may feel overwhelming. Reddy N, Calloni SF, Vernon HJ, Boltshauser E, Huisman TAGM, Soares BP. As you and your caregivers adjust to a rare disease diagnosis, it is normal to be flooded with a wide range of emotions. Imaging in neonatal maple syrup urine disease. Imaging in classic form of maple syrup urine disease: a rare metabolic central nervous system. Diffusion-weighted magnetic resonance imaging in a case of severe classic maple syrup urine disease. Management involves dietary changes, such as life-long dietary intake restriction of foods with branched-chain amino acids (especially leucine), and early treatment of metabolic decompensation, with agents such as intravenous glucose 9. MR spectroscopy: single-voxel proton MR spectroscopy may show the presence of branched-chain amino acids and branched-chain alpha-keto acids resonating at 0.9-1.0 ppm, especially during a metabolic crisis 1,2.DWI: the posterior limbs of the internal capsules and optic radiations and the central corticospinal tracts within the cerebral hemispheres exhibit high diffusion signal.predominantly in the cerebellar white matter, cerebral peduncles, dorsal brainstem, posterior limb of the internal capsule, thalami, globe pallidi, and perirolandic cerebral white matter 8.vasogenic edema: usually due to disruption of the blood-brain barrier during an acute metabolic crisis or decompensation 8.intramyelinic edema: believed to be from myelin splitting due to accumulation of branched-chain key acids and water molecules between layers of myelin 8.It is caused by a deficiency of branched-chain alpha-ketoacid dehydrogenase complex (BCKDC), the second enzyme of the metabolic pathway of the three BCAAs, leucine, isoleucine, and.
MRI brain may show the characteristic pattern of edema present in MSUD. Maple syrup urine disease (MSUD, MIM 248600) also known as branched-chain ketoaciduria, is a disorder affecting the aliphatic or branched-chain amino acids (BCAAs). There is elevated plasma concentrations of branched-chain amino acids (leucine, isoleucine, and valine), allo-isoleucine, and alpha-ketoacids. It is inherited in an autosomal recessive pattern and various different genes have been implicated 1. Maple syrup urine disease is due to mutations in any aspect of the mitochondrial branched-chain alpha-keto acid dehydrogenase complex 8. Intermittent forms of the disease may present later (5 months to 2 years of age) and can be precipitated by concomitant infection or a high protein intake 8.
