Inborn errors of metabolism (IEM) are a group of inherited metabolic disorders leading to enzymatic defects in the human metabolism. As its name implies, inborn errors means birth defects in newborn infants which passed down from family and affecting metabolism.

What are some examples of inborn error of metabolism?

Inborn errors of metabolism are rare genetic (inherited) disorders in which the body cannot properly turn food into energy….A few of them are:

  • Fructose intolerance.
  • Galactosemia.
  • Maple sugar urine disease (MSUD)
  • Phenylketonuria (PKU)

Galactose. Galactosemia, the inability to metabolize galactose in liver cells, is the most common monogenic disorder of carbohydrate metabolism, affecting 1 in every 55,000 newborns.

What are the disorders diseases related to carbohydrates metabolism?

Disorders of carbohydrate metabolism occur in many forms. The most common disorders are acquired. Acquired or secondary derangements in carbohydrate metabolism, such as diabetic ketoacidosis, hyperosmolar coma, and hypoglycemia, all affect the central nervous system.

What is the most common inborn error of metabolism worldwide?

Phenylketonuria Clinic The most common form of PKU results from the absence of a single enzyme, phenylalanine hydroxylase and is the most common known inborn error of metabolism.

How do you treat inborn errors of metabolism?

The management of inborn errors of metabolism has traditionally consisted in diet therapy and supportive therapy, but recently other treatment options have become available, including enzyme and coenzyme replacement, removal of harmful substances, cell and organ transplantation, and gene therapy.

What are the deficiency diseases of carbohydrate?

When you don’t get enough carbohydrates, the level of sugar in your blood may drop to below the normal range (70-99 mg/dL), causing hypoglycemia. Your body then starts to burn fat for energy, leading to ketosis. Symptoms of hypoglycemia include: Hunger.

What are disorders of carbohydrate metabolism explain in brief diabetes mellitus?

Diabetes mellitus is a group of metabolic disorders of carbohydrate metabolism characterized by high blood glucose levels (hyperglycemia) and usually resulting from insufficient production of the hormone insulin (type 1 diabetes) or an ineffective response of cells to insulin (type 2 diabetes).

What is the deficiency of carbohydrates?

When you don’t get enough carbohydrates, the level of sugar in your blood may drop to below the normal range (70-99 mg/dL), causing hypoglycemia. Your body then starts to burn fat for energy, leading to ketosis.

Some findings in patients with IEM may include elevated acid levels in the blood, low blood sugar, high blood ammonia, abnormal liver function tests, and blood cell abnormalities. Certain patients may also have neurologic abnormalities such as seizures and developmental delays. Growth may also be affected.
