-
Inborn errors of metabolism
- rare genetic disorder in which the body cannot properly turn food into energy
- usually caused by defects in specific proteins that helps body break down food
-
side effects
- food product that is not metabolized can build up and cause problems.
- can cause developmental delays
- diet change can help
- type and extent of change depends on specific error
-
newborn screening
- detection is complicated
- symptoms are nonspecific
- most infants look normal at birth
-
nonselective neonatal screening
- screening of all newborns
- goal is early identification and treatment before signs and symptoms show up
-
selective neonatal screening
- known to be at risk
- siblings
- confirmatory testing of a positive neonatal screening test
-
-
tandem mass spectroscopy
allows for the screening for over 30 disorders by analyzing metabolites in a blood spot collected on a filter paper
-
most common
- fructose intolerance
- galactosemia
- maple sugar urine disease
- phenylketonuria
-
fructose intolerance
- person lacks protein needed to break down fructose
- if consumed, chemical changes occur in the body
- body cannot change its energy storage material into glucose
- blood sugar falls and substances build up in the liver
-
symptoms for fructose intolerance
- can be seen after baby starts formula or food
- convulsions
- excessive sleepiness
- irritability
- jaundice
- poor feeding as baby
- problems after eating fruits
- vomiting
- removing fructose and sucrose in diet -treatment
-
Glactosemia
- body is unable to use simple sugar galactose

- cannot tolerate any form of milk
-
treatment of galactosemia
- avoid all milk-containing products
- infants can be fed with soy formula, meat-based formula, lactose-free formula
- calcium supplements
-
Maple Sugar Urine Disease
- metabolism disorder passed down through families
- body cannot break down certain parts of proteins
- smells like maple syrup
- gene defect
-
treatment of MSUD
- diet free of branched-chain amino acids is started when amino acid levels are normal
- man-made infant formula with low levels of amino acids leucine, isoleucine and valine
- follow diet to prevent nervous system damage
- requires frequent blood tests
- life threatening
-
Phenylketonuria
- genetic disorder
- cannot process part of phenylaline- in almost all foods
- damage brain and cause mental retardation
-
treatment for pku
- diet of low-protein foods
- includes many fruits and vegetables
- some low-protein breads, pastas, cereals
- special formula, made without Phe to help with vitamins and minerals
- for life
-
symptoms of pku
- normal at birth
- 3-6 months begin to lose interest in surroundings
- age 1 developmentally delayed and skin has less pigmentation
- IDDs
-
eating disorders
- serious emotional and physical problems that can have life-threatening consequences for females and males
