MSUD CASE STUDY

MRI was obtained and showed restricted diffusion involving the corticospinal tracts, thalami, globus palladi, midbrain, dorsal brain stem, and cerebellar white matter [ Figure 1 ]. AU – Brown, Ronald T. Onset of clinical symptoms and protein levels in the blood and urine may vary depending on the amount of protein in the feeding regimen. The condition shows in five different clinical phenotypes as classic, intermediate, intermittent, thiamine-responsive and E3 deficiency type [ 3 ]. His physical examination during initial admission showed moderate dehydration and lethargy. If untreated, various neurological complications including seizures or coma may occur, as BCAAs, especially leucine, are cytotoxic to brain cells, leading to cytotoxic brain edema affecting the myelinated white matter as was seen in the diffusion-weighted imaging DWI of our patient.

AU – Brown, Ronald T. DWI top row and corresponding apparent diffusion coefficient bottom row demonstrate marked restricted diffusion because of cytotoxic edema involving the cerebellar white matter, dorsal brain stem, thalami, globus palladi, and internal capsules. In addition, diffuse white matter abnormalities may be seen on T2-weighted sequences [ Figure 2 ]. The parents of the infant were first-degree cousins. Chuang D, Shih V. He did not have any evidence of overt obtundation or emesis.

Following the path of these studies, new studies about using nitrogen scavenging agents in MSUD patients to reduce branched-chain amino acid levels are also in progress [ 6 ]. Financial support and sponsorship Nil.

However, elevation in plasma amino acid levels may not appear until after the first week of life. There must be ways to screen for this disease as well.

BCKCD is a 4-million Dalton macromolecule and consists of heterodimeric E1 decarboxylase component E1a and E1b subunitsE2 transacylase that consists of 24 subunits and 1 homodimer E3 component [ 2 ]. T1 – A case study of maple syrup urine disease, dietary caes and neuropsychological performance.

He was brought to the doctor who diagnosed him with MSUD. Despite this diet, he still suffered from chronic and severe metabolic crises.

During discharge of the patient, neurological examination showed spasticity of lower extremity so baclofen treatment was started. Phenylbutyrate does not accumulate in plasma and converted into phenylacetate which is its active form. Selected tests of neuropsychological and cognitive functioning, administered before dietary treatment and immediately following metabolic stabilization and at 5-week follow-up, indicated considerable clinical sttudy.

It is then conjugated with glutamine in liver and kidney to form phenylacetylglutamine which is excreted in shudy, replacing urea as a mean of eliminating excess nitrogen compounds [ 458 ]. I feel that the option of BCKD supplementation in conjunction with dietary regulation should be considered over a liver transplant. Time of onset may vary depending on the amount of protein in the feeding regimen. The patient was thereafter admitted to our hospital where he exhibited irritability, hypertonicity, high-pitched cry, and sleepiness.
