How common is maple syrup urine disease (MSUD)?
Thiamine-responsive: This type of MSUD responds to treatment using high doses of vitamin B1 (thiamine) along with a restricted diet. With treatment, people with thiamine-responsive MSUD have higher tolerance for the three amino acids. How common is maple syrup urine disease (MSUD)? MSUD is very rare.
Can thiamine be used to treat maple syrup urine disease?
Some doctors have recommended thiamine therapy as a way of checking whether a patient's maple syrup urine disease is the thiamine-responsive type. However, regardless of the circumstances, thiamine alone cannot be used as a sole treatment for this condition.
What is the second tier test for maple syrup urine disease?
Second-tier test for quantification of alloisoleucine and branched-chain amino acids in dried blood spots to improve newborn screening for maple syrup urine disease (MSUD) Clin Chem. 2008;54(3):542–549. [PubMed] [Google Scholar] 31.
How long can you live with maple syrup urine disease?
If untreated, life-threatening coma or respiratory failure can occur within 7 to 10 days and death can occur within the first two months. Upon any lapse of treatment, classic MSUD can cause brain damage.
Can you live with maple syrup urine disease?
However, treatment for MSUD must be continued for life. Without treatment, severe, life-threatening symptoms can develop, including seizures (fits) or falling into a coma. Some children with untreated MSUD are also at risk of brain damage and developmental delay.
What is maple syrup urine disease symptoms?
The condition gets its name from the distinctive sweet odor of affected infants' urine. It is also characterized by poor feeding, vomiting, lack of energy (lethargy), abnormal movements, and delayed development. If untreated, maple syrup urine disease can lead to seizures, coma, and death.
What causes maple syrup urine disease in adults?
MSUD is caused by mutations or changes in some of your genes. Those changes prevent your body from making enzymes that break down three amino acids in proteins—leucine, isoleucine, and valine. MSUD is recessive, so you must have inherited two copies of the mutated genes to have symptoms.
Is genetic counseling an option for MSUD?
MSUD follows an autosomal recessive inheritance pattern and genetic counseling is possible.
What tests are done for MSUD?
The test is performed within 24-48 hours following birth. Newborn screening for maple syrup urine disease is performed with tandem mass spectrometry (MS/MS) using concentrations of leucine and isoleucine and the Fisher ratio (branch-chain amino acids/phenylalanine and tyrosine) as diagnostic measures.
What is maple syrup urine disease?
Maple syrup urine disease (MSUD) is a rarely occurring disorder passed down through families. It is characterized by the body having a deficient supply of certain enzymes used to break down amino acids. Because of this, the amino acids valine, isoleucine, and leucine build up throughout the body in abnormal amounts.
How to cure maple urine disease?
One treatment option a doctor may recommend is a liver transplant. Usually, this is done when the patient is still a child. There have been some reported cases where, following a transplant, previously afflicted children had their maple urine disease cured. Their metabolism corrected itself and began to break down the amino acids as it was meant to. A transplant is successful when it cures the disease and allows the child to eat an unrestricted diet. This is the only known cure for maple syrup urine disease.
What happens when you have maple syrup in your urine?
CBS News. A patient with maple syrup urine disease is constantly at risk of a metabolic crisis , even if they follow a strict diet. A metabolic crisis occurs when the amino acid levels in the blood get too high. Patients must be treated with emergency medical intervention to lower their amino acid levels, particularly their levels of leucine.
Is maple syrup a good cure for urine disease?
A transplant is successful when it cures the disease and allows the child to eat an unrestricted diet. This is the only known cure for maple syrup urine disease. Transplants can sometimes be risky, so it's important for everyone involved to weigh the benefits and the risks. The biggest long-term concern for patients tends to be immunosuppression.
Can thiamine be used for maple syrup?
However, regardless of the circumstances, thiamine alone cannot be used as a sole treatment for this condition. It is always used alongside a restrictive diet, and sometimes with other therapies as well. It can treat a variety of conditions, including metabolic disorders like maple syrup urine disease, though this disease does not always respond ...
Can maple syrup cause brain damage?
If not appropriately treated, this disease can lead to neurological problems. If not treated at all, brain damage will occur, followed by death. There are a number of treatment methods available for maple syrup urine disease.
Does maple syrup cause pain?
Maple syrup urine disease will sometimes have complications requiring management with pain medication. The basic symptoms don't cause pain, but a buildup of amino acids will cause other symptoms. With classic cases, individuals are not able to metabolize protein, so they experience bone loss, making them susceptible to fractures.
What is the treatment for maple syrup?
Treatment for maple syrup urine disease (MSUD) involves a protein -restricted diet and supplements. With early treatment, people with MSUD avoid many of the more severe symptoms. Guidelines exist for medical and diet management of people with MSUD. [1] [4] [5]
What is the cause of maple syrup urine disease?
Maple syrup urine disease (MSUD) occurs when the body is unable to breakdown certain parts of proteins. This leads to the build-up of toxic substances that can cause organ and brain damage. There are several forms of MSUD.
What is MedlinePlus Genetics?
MedlinePlus Genetics contains information on Maple syrup urine disease. This website is maintained by the National Library of Medicine.
How is MSUD diagnosed?
In some cases, especially in adolescents and adults, MSUD is diagnosed based on the symptoms, clinical exam, and the results of urine and blood testing. The results of genetic testing may help confirm the diagnosis. [1] [3] Last updated: 12/28/2020.
What does MSUD smell like?
If untreated, respiratory failure (lack of oxygen getting to the blood) may occur. The earwax and urine of infants with MSUD smells like maple syrup. The symptoms of other forms of MSUD start in adolescence or adulthood. MSUD is caused by genetic variants in the BCKDHA, BCKDHB, or DBT genes. It is inherited in an autosomal recessive pattern.
How is maple syrup inherited?
Maple syrup urine disease is inherited in an autosomal recessive pattern. [1] All individuals inherit two copies of each gene. Autosomal means the gene is found on one of the numbered chromosomes found in both sexes. Recessive means that both copies of the responsible gene must be changed to have the condition.#N#People with autosomal recessive conditions inherit one variant from each of their parents. The parents, who each have one gene variant, are known as carriers. Carriers of an autosomal recessive condition typically do not have any signs or symptoms (they are unaffected). When two carriers of an autosomal recessive condition have children, there is a 25% (1 in 4) chance to have a child with the condition.
How many people are born with maple syrup?
It has been estimated that about one in 150,000 to one in 185,000 people is born with maple syrup urine disease. The prevalence may be higher in specific ethnic groups. The exact number of people living with MSUD is unknown. [1] [4]
