As many of you may know, September is Newborn Screening awareness month!
Many people do know what newborn screening is or what it does until there child is diagnosed with something. Many people just know it as the heal poke test. it is my goal for September to educate as many friends and followers as I can in what it is, what it does, and why it is important. It saddens me to hear how many parents wish they could denies newborn screening to save their baby from the “pain” or “torture” or just from being “poked and prodded” so much after birth. specially if the birth is traumatic. As a nurse and a women with PKU I feel that education is so important and should be apart of birthing and pregnancy education. I wish all nurses, doulas and mid wife’s would include it in the education and support for new mom’s.
With out newborn screening, and with out being able to detect many of these genetic and metabolic diseases, my life and many life’s would be effected to so negatively. People with PKU would not have the quality of life that we do now, we would be mentally retarded , and or institutionalized. to think that mental retardation is one of the best outcomes in a child not screened at birth is scary. Because there are diseases that are screened for at birth that if treated can lead to a healthy baby but if not diagnosed and not treated , could lead to infant death!!
Here is some important information about new born screening, please feel to pass this blog post on to your friends and family to help spread awareness and education.
What is newborn screening?
A: Newborn screening is a public health program designed to screen infants shortly after birth for a list of conditions that are treatable, but not clinically evident in the newborn period. Some of the conditions included in newborn screening programs are only detectable after irreversible damage has been done, in some cases sudden death is the first manifestation of the disease.
Is newborn screening free or do I have to pay for it?
A; Newborn screening is covered in Canada by the government and is no cost to the family. It is covered by medical. Screening programs are often run by state or national governing bodies with the goal of screening all infants born in the jurisdiction. The number of diseases screened for is set by each jurisdiction, and can vary greatly
How is newborn screening done?
A: Most newborn screening tests are done by measuring metabolites and enzyme activity in whole blood samples collected on specialized filter paper, however many areas are starting to screen infants for hearing loss using automated auditory brainstem response and congenital heart defects using pulse oximetry. Infants who screen positive undergo further testing to determine if they are truly affected with a disease or if the test result was a false positive. Follow-up testing is typically coordinated between geneticists and the infant’s pediatrician orprimary care physician.
When did Newborn screening start?
A; Newborn screening debuted as a public health program in the United States in the early 1960s, and has expanded to countries around the world, with different testing menus in each country. ( fact: Babies born with PKU before newborn screening are mentally retarded and some live in group homes. After newborn screening was started doctors and scientists went back and re tested some of the mentally retarded patients and discovered they to had PKU)
What was the first disease screened for by newborn screening?
A : The first disorder detected by modern newborn screening programs was phenylketonuria
Who discovered newborn screening?
A: Robert Guthrie developed a simple method using a bacterial inhibition assay that could detect high levels of phenylalanine in blood shortly after a baby was born. Guthrie also pioneered the collection of blood on filter paper which could be easily transported, recognizing the need for a simple system if the screening was going to be done on a large scale. Newborn screening around the world is still done using similar filter paper.
What was the second disease screened for with newborn screening?
A; Congenital hypothyroidism was the second disease widely added in the 1970s. Robert Guthrie and colleagues also developed bacterial inhibition assays for the detection of maple syrup urine disease andclassic galactosemia.
How many diseases does newborn screening sceen for?
A: The number of diseases screened for at birth varies from country to country. Here in Canada we screen for many of the detectable diseases, however not all of them!
The common diseases screened for are :
Amino Acid disorders such as :
phenylketonuria
Fatty Acid oxidation disorders such as :
Medium chain acyl-CoA dehydrogenase deficiency (MCADD)
Endocrinopathies disorders such as :
congenital hypothyroidism
congenital adrenal hyperplasia (CAH)
Hemoglobinopathies disorders such as :
sickle cell disease.
Organic acidemias disorders are screened for 3 weeks after birth through the urine and include :
propionic acidemia
methylmalonic acidemia
isovaleric acidemia.
Newborn screening also screens for Cystic Fibrosis. Cystic fibrosis (CF), also known as mucoviscidosis, is an autosomal recessive genetic disorder that affects most critically the lungs, and also the pancreas, liver, and intestine. It is characterized by abnormal transport of chloride and sodium across an epithelium, leading to thick, viscous secretions.
Note : While I was admitted to BC Children’s hospital as a youth for my high levels, I was on the floor with some of the CF patients and made many good friends, including my friend Sara who was so dear to me and we bonded , she was my inspiration to get better and to look after myself. Sara passed away at age 20 in 2006. It broke my heart to loose her and I will miss her forever. RIP Sara.
Urea cycle disorders that include :
citrullinemia,
argininosuccinic aciduria
argininemi
a select few pilot programs are being done in some american states for new born screening of Lysosomal storage disorders.
Hearing loss is also screened for at birth,
Newborn hearing testing is done at the bedside using transiently evoked otoacoustic emissions, automated auditory brain stem responses or a combination of both techniques.
Congenital heart defects are not included in newborn screening by using a pulse oximiter at the bed side.
Severe combined immunodeficiency are also screened in some states , screening started in wisconsin in 2008 but has not yet been adapted world wide.
Other diseases screened for are :
Duchenne muscular dystrophy (DMD)
Adrenoleukodystrophy (ALD)
These are just some if the diseases and disorders that are screened for at birth, there are many more and not all states and provinces screen for the same disorders. I hope that one day that all the diseases and disorders that can be detected with new born screening will be mandatory and screened for at birth internationally.
Newborn screening saves lives and saves babies. it is so nice to see the efforts by others who are campaigning for newborn screening and working hard at spreading awareness. I am so grateful to them all and wish to recognize there hard work by giving thanks and showing my appreciation and by dedicating this blog post to all those who work with newborn screening. With out them and with out Robert Guthrie I would not be the person that I am today. with our with out PKU my life would not be the same.
I also must take note, I do not take credit for the information in this post. much of the information and facts are taken from various websites, and wikapedia.
For more information on new born screening please speak to your doctor or if you a British Columbia resident please visit the following site : http://www.bcwomens.ca/Services/PregnancyBirthNewborns/NewbornCare/NewbornScreeningProgram/default.htm
you can also search newborn screening in google or facebook and come up with many wonderful and informative sources, groups and fan pages.
I apologize if any of the above information is incorrect and if so , please feel free to message me and I will be happy to correct it.
So in conclusion, please educate yourself, your spouse, your children and your friends and family on the importance of newborn screening and always remember newborn screening saves lives! and saves babies!
